Chemical corrosion resistance test of thermal fuse: a key step to ensure quality

In the application scenarios of thermal fuses, its chemical corrosion resistance is a crucial performance indicator. Whether it is used in industrial manufacturing, automobile production or electronic and electrical fields, thermal fuses may be corroded by various chemical substances. For enterprises engaged in the foreign trade of thermal fuses, clearly showing the chemical corrosion resistance test process and results of products to international wholesale buyers will help enhance customer confidence in the products and improve the market competitiveness of products. This article will explore the relevant content of chemical corrosion resistance test of thermal fuses in depth.

1. The importance of chemical corrosion resistance test of thermal fuses
(I) Dealing with diversified application scenarios
The scope of use of thermal fuses is extremely wide, and there are various chemical substances in different application scenarios. For example, in the automobile manufacturing industry, thermal fuses may come into contact with various liquids inside the car, such as brake fluid, coolant, etc., which have certain chemical corrosion. In the field of electronic and electrical appliances, thermal fuses may be corroded by various electronic chemical reagents, cleaning agents, etc. If the chemical corrosion resistance of the thermal fuse is insufficient, it may lead to its performance degradation or even breakage, affecting the normal use and safety of the product. By conducting chemical corrosion resistance tests, we can understand the performance of thermal fuses in different chemical environments in advance, thereby ensuring their reliability and stability in practical applications.
(II) Meeting quality standards
International quality standards for thermal fuses are becoming increasingly stringent. As a key quality indicator, chemical corrosion resistance needs to comply with corresponding standards and specifications. Many countries and regions have formulated relevant standards and put forward clear requirements for the corrosion resistance of thermal fuses in different chemical media. For example, some standards stipulate indicators such as corrosion resistance time and corrosion depth of thermal fuses in acidic, alkaline and specific solvent environments. Only by passing strict chemical corrosion resistance tests can thermal fuse products obtain relevant certifications, enter the international market, and meet the quality supervision requirements of different countries and regions.
(III) Improving product competitiveness
In the global market competition, thermal fuse products with good chemical corrosion resistance can stand out and attract more international wholesale buyers. When buyers choose thermal fuse suppliers, product quality and performance are one of the primary factors they consider. By showing a detailed chemical corrosion resistance test process and excellent test results, buyers can intuitively feel the advantages of the product and enhance their willingness to cooperate with the company. This will not only help expand the market share of the product, but also improve the brand awareness and reputation of the company, laying a solid foundation for the long-term development of the company.

2. Common methods for testing the chemical corrosion resistance of thermal fuses

(I) Immersion method

The immersion method is one of the most commonly used, simple and intuitive methods for testing chemical corrosion resistance. The specific operation steps are as follows:

Prepare the test solution: According to the actual use environment of the thermal fuse or the requirements of relevant standards, prepare chemical solutions of specific concentrations and types, such as sulfuric acid, hydrochloric acid, sodium hydroxide, ethanol, etc. These solutions can simulate the chemicals that the thermal fuse may be exposed to in different application scenarios.

Sample preparation: Cut the thermal fuse into samples of a certain length and shape to ensure that the surface of the sample is clean, free of oil and impurities. It is usually necessary to weigh the sample accurately and record the initial mass.

Immersion process: The thermal fuse sample is completely immersed in the test solution and placed in a constant temperature water bath or incubator to maintain a certain temperature and time. The immersion time can be set according to different test requirements, generally ranging from several hours to several days. During the immersion period, it is necessary to regularly observe the changes on the sample surface, such as whether there is discoloration, swelling, dissolution, etc.
Testing and analysis: After the immersion is completed, the sample is taken out of the solution and rinsed with distilled water to remove the residual chemicals on the surface. Then the sample is dried, weighed again, and its mass loss rate is calculated. At the same time, the microscopic morphological changes on the sample surface can be observed with the help of instruments such as microscopes and scanning electron microscopes (SEMs), and the morphology and degree of corrosion, such as the depth and distribution of corrosion pits, can be analyzed.
The advantages of the immersion method are simple operation, low cost, and can intuitively reflect the corrosion resistance of the thermal fuse in different chemical media. However, this method also has certain limitations, such as the inability to accurately control the chemical reaction kinetics in the solution, and the corrosion behavior in some complex chemical environments may not be fully and accurately evaluated.
(II) Electrochemical test method
The electrochemical test method is a more advanced chemical corrosion resistance test method, which evaluates the corrosion resistance of the thermal fuse by measuring the electrochemical parameters of the thermal fuse in the electrolyte solution. Commonly used electrochemical testing techniques include potential-time curve method, polarization curve method and electrochemical impedance spectroscopy (EIS).
Potential-time curve method: The thermal fuse sample is used as the working electrode, together with the reference electrode and the auxiliary electrode to form an electrochemical test system, and immersed in the electrolyte solution. Under constant current or potential conditions, the potential change curve of the working electrode is recorded over time. The change in potential can reflect the progress of the corrosion reaction on the surface of the thermal fuse. For example, a rapid drop in potential may indicate the acceleration of the corrosion reaction.
Polarization curve method: By changing the potential of the working electrode and measuring the corresponding current density change, a polarization curve is drawn. The polarization curve can provide important information such as the corrosion current density and corrosion potential of the thermal fuse at different potentials, so as to calculate the relevant parameters of its corrosion rate and corrosion resistance. Generally speaking, the smaller the corrosion current density, the better the corrosion resistance of the thermal fuse.
Electrochemical impedance spectroscopy (EIS): Under the action of AC voltage, the impedance of the thermal fuse electrode is measured as a function of frequency to obtain an impedance spectrum. By analyzing the various characteristic parameters in the impedance spectrum, such as charge transfer resistance, double layer capacitance, etc., we can gain an in-depth understanding of the corrosion reaction mechanism and process on the surface of the thermal fuse. For example, a larger charge transfer resistance usually means that the thermal fuse has better corrosion resistance, because this indicates that the corrosion reaction is greatly hindered.
The advantage of the electrochemical test method is that it can provide rich electrochemical information, in-depth understanding of the corrosion behavior and mechanism of the thermal fuse, and the test results have high accuracy and repeatability. However, this method requires professional electrochemical testing equipment and experimental operation skills, the test cost is relatively high, and the requirements for the test environment and solution conditions are relatively strict.
(III) Weight loss method
The weight loss method is a traditional method to evaluate the chemical corrosion resistance of the thermal fuse by measuring the mass loss before and after chemical corrosion. The specific steps are as follows:
Sample preparation: Cut the thermal fuse sample into a regular shape, such as a circle or square, and accurately measure its initial mass to the milligram level. At the same time, record the sample size, surface area and other parameters for subsequent calculation of the corrosion rate.
Corrosion test: expose the sample to a specific chemical corrosion environment, such as acid mist, alkali mist or chemical reagent vapor, or immerse it in a specific corrosion solution. According to different test requirements, control the time, temperature and humidity of the corrosion test.
Mass measurement: After the corrosion test, take out the sample and carefully clean it to remove the corrosion products and impurities on the surface. After drying, accurately measure the mass of the sample again and calculate its mass loss.
Result calculation and analysis: According to the mass loss and the surface area, time and other parameters of the sample, calculate the corrosion rate of the thermal fuse, usually expressed in units such as mg/(dm²・h) or g/(m²・h). The smaller the corrosion rate, the better the chemical corrosion resistance of the thermal fuse. At the same time, the surface morphology observation and microstructure analysis of the sample can be combined to further understand the cause and mechanism of corrosion.
The advantage of the weight loss method is that the concept is simple, easy to understand and operate, and can directly reflect the mass loss of the thermal fuse. But its disadvantage is that the test cycle is long, especially in the case of slow corrosion rate, it may take days or even weeks to obtain obvious results. In addition, the cleaning and drying process of corrosion products on the sample surface may affect the accuracy of the test results.

3. Standard Specifications for Chemical Corrosion Resistance Test of Thermal Fuses
Globally, multiple organizations and institutions have formulated relevant standard specifications for chemical corrosion resistance tests of thermal fuses. These standards provide a basis for enterprises to conduct product quality control and market access.
(I) International Organization for Standardization (ISO)
ISO has formulated a series of corrosion test standards related to plastics, chemical products, etc., some of which can also be applied to chemical corrosion resistance tests of thermal fuses. For example, ISO 4628 specifies the corrosion degree assessment method for coatings and plastic coatings, including the appearance evaluation of corrosion products and the measurement of corrosion depth. ISO 9227 describes in detail the conditions and methods of salt spray corrosion tests. Although it is mainly used for testing metal materials, it also has certain reference value for studying the corrosion resistance of thermal fuses in salt spray environments. These standards are widely recognized and universal internationally, and quality inspection agencies in many countries and regions conduct testing and certification based on ISO standards.
(II) American Society for Testing and Materials (ASTM)
ASTM has developed a series of test standards for different materials and products, some of which involve the chemical corrosion resistance test of thermal fuses. For example, the ASTM D543 standard specifies the test methods for the corrosion resistance of plastic materials under the action of chemical reagents, including immersion method, drip method, etc. The standard describes in detail the preparation of the test solution, the control of the test conditions, and the evaluation method of the results, providing detailed guidance for enterprises and testing institutions. In addition, the ASTM G31 standard regulates the immersion corrosion test of metal materials. Although it is mainly applicable to metals, some of the test principles and methods can provide reference for the chemical corrosion resistance test of thermal fuses. In the North American market, ASTM standards are widely used in product quality testing and evaluation. If thermal fuse products want to enter this market, they usually need to meet the relevant ASTM standard requirements.
(III) European standards (EN)
European standards also have corresponding specifications for the chemical corrosion resistance test of thermal fuses. For example, the EN ISO 9227 standard corresponds to ISO 9227 and provides detailed regulations for salt spray corrosion tests. In addition, the EN 1670 standard specifies the test methods for the chemical corrosion resistance of building materials and components. Some of the test conditions and evaluation indicators can also be applied to the chemical corrosion resistance evaluation of thermal fuses when they are used in the construction field. European standards emphasize the rigor and scientific nature of the test, and their test results have high authority and credibility in the European market. For foreign trade companies of thermal fuses, understanding and following European standards will help expand the European market.

4. Factors Affecting the Test Results of Chemical Corrosion Resistance of Thermal Fuse
(I) Test Environment Conditions
Test environment conditions have a significant impact on the test results of chemical corrosion resistance of thermal fuse. Changes in factors such as temperature, humidity, solution concentration, and solution pH value will change the reaction rate and reaction mechanism between the thermal fuse and the chemical medium.
Temperature: Generally speaking, an increase in temperature will accelerate the chemical reaction and speed up the corrosion rate of the thermal fuse. For example, under high temperature conditions, the molecular motion of the thermal fuse intensifies, the collision frequency with the chemical medium increases, and it is more likely to cause chemical bond breakage and corrosion reaction. Therefore, when conducting chemical corrosion resistance tests, it is necessary to strictly control the test temperature and select a suitable test temperature range according to the requirements of the actual use environment.
Humidity: In some corrosion tests, such as salt spray corrosion tests, humidity plays an important role in the corrosion behavior of thermal fuses. In a high humidity environment, a water film is easily formed on the surface of the thermal fuse, which promotes the adsorption and diffusion of the corrosive medium, thereby intensifying the corrosion reaction. In a dry environment, the corrosion reaction may be relatively slow. Therefore, accurately controlling the humidity of the test environment is one of the key factors to ensure the accuracy and reliability of the test results.
Solution concentration: The concentration of the chemical solution directly affects the amount of chemical medium that the thermal fuse contacts. A high concentration of acidic or alkaline solutions is usually more corrosive and can produce obvious corrosion effects on the thermal fuse in a short time. In low concentration solutions, the corrosion reaction may be slow, and a longer test time is required to observe significant corrosion phenomena. Therefore, when selecting the test solution concentration, the actual use environment of the thermal fuse and the concentration range of chemical substances that may be exposed should be fully considered.
Solution pH: The pH value of the solution is a key factor in determining its acidity and alkalinity, and has an important impact on the test results of the chemical corrosion resistance of the thermal fuse. Different thermal fuse materials have different corrosion resistance in different pH environments. For example, some thermal fuses may show good corrosion resistance in acidic environments, but are prone to corrosion in alkaline environments; while other thermal fuses are the opposite. Therefore, before testing, it is necessary to clarify the actual use pH environment of the thermal fuse and select the corresponding test solution pH value for simulation.
(II) Preparation of test samples
The preparation process of test samples will also affect the test results of chemical corrosion resistance. The size, shape, surface treatment method and other factors of the sample may affect its contact area and reaction degree with the chemical medium.
Size and shape: The contact area of ​​hot-melt samples of different sizes and shapes with the chemical medium during the test process is different, which may lead to differences in the rate and degree of corrosion reaction. Generally speaking, samples with larger surface areas are relatively more susceptible to corrosion because they have more opportunities to contact with chemical media. Therefore, when preparing test samples, the consistency of sample size and shape should be ensured as much as possible to reduce the dispersion of test results.
Surface treatment: The surface treatment method of hot-melt, such as cleaning, grinding, coating, etc., will significantly affect its surface state and corrosion resistance. For example, incomplete surface cleaning may cause residual oil, impurities, etc. on the surface of the sample. These substances may react with the chemical medium during the test and interfere with the test results. Different degrees of surface grinding will result in different surface roughness of the sample. Surfaces with larger roughness may be more likely to absorb corrosive media and accelerate corrosion reactions. In addition, some surface coatings can play a certain protective role and improve the chemical corrosion resistance of the thermal fuse, but the composition and thickness of the coating need to be clarified during the test process in order to accurately evaluate the corrosion resistance of the thermal fuse itself.
(III) Selection of test methods
Different test methods focus on different corrosion behaviors and performance indicators, so choosing a suitable test method is crucial to accurately evaluate the chemical corrosion resistance of the thermal fuse.
Immersion method: As mentioned above, the immersion method mainly evaluates the corrosion resistance of the thermal fuse by observing the macroscopic changes and mass loss of the thermal fuse in the chemical solution. This method is suitable for preliminary screening of thermal fuse materials or qualitative analysis of corrosion resistance. However, since the immersion method cannot accurately control the kinetic conditions of the chemical reaction and has low detection sensitivity for some local corrosion phenomena, it may be necessary to combine other test methods when the corrosion resistance of the thermal fuse needs to be studied in depth and accurately quantified.
Electrochemical test method: The electrochemical test method can provide electrochemical information of the thermal fuse in the chemical medium, such as corrosion potential, corrosion current density, impedance, etc., so as to gain a deep understanding of the mechanism and kinetic process of the corrosion reaction. This method has high sensitivity and accuracy, and can detect early signs of corrosion and minor corrosion changes in thermal fuses. However, the electrochemical test method has high requirements for test equipment and experimental operation, and the analysis and interpretation of test results require professional electrochemical knowledge. In addition, electrochemical testing is usually carried out in a specific electrolyte solution, and its test results may not fully represent the corrosion resistance of thermal fuses in actual complex chemical environments.
Weight loss method: The weight loss method is a traditional and direct test method that reflects the chemical corrosion resistance of thermal fuses by measuring the mass loss of thermal fuses. The advantage of this method is that the results are intuitive, easy to understand and calculate. However, its test cycle is long, especially for thermal fuse materials with good corrosion resistance, it may take a long time to obtain significant mass loss data. Moreover, during the mass loss measurement process, the cleaning and drying of corrosion products on the sample surface may affect the accuracy of the test results.
(IV) Selection of chemical medium
The selection of chemical medium should be determined according to the actual use environment of the thermal fuse and the chemicals that may be exposed to it. Different chemical media have different corrosion mechanisms on thermal fuses, so choosing a suitable chemical medium for testing is the key to simulating actual use and accurately evaluating chemical corrosion resistance.
Acidic media: Common acidic media include sulfuric acid, hydrochloric acid, nitric acid, etc., which may exist in various industrial wastewaters, acidic detergents or chemical reaction environments in the actual application of thermal fuses. Different acids have different corrosion behaviors on thermal fuses. For example, hydrochloric acid is a strong acid with high reactivity. It can quickly react chemically with the thermal fuse to generate corresponding chlorides and water, and release a large amount of heat. In addition to being highly acidic, nitric acid is also highly oxidizing, which can cause oxidation reactions on the surface of the thermal fuse to form an oxide layer, thereby affecting the corrosion behavior of the thermal fuse. Therefore, when selecting an acidic medium for testing, it is necessary to make a reasonable choice based on the specific application scenarios of the thermal fuse and the types and concentrations of acids that may be exposed.
Alkaline media: Alkaline media such as sodium hydroxide and potassium hydroxide are also common in some application scenarios of thermal fuses, such as alkaline detergents and alkaline reaction systems in chemical production. The corrosion behavior of thermal fuse in alkaline medium is different from that in acidic medium. Alkaline medium may cause saponification or hydrolysis reaction with certain components in thermal fuse, resulting in the degradation of thermal fuse performance. For example, some thermal fuses containing ester or amide groups are prone to hydrolysis in alkaline environment, causing the molecular chain to break, thereby reducing the strength and toughness of the thermal fuse. Therefore, it is necessary to select suitable alkaline medium for chemical corrosion resistance test for different thermal fuse materials and use environments.
Organic solvent medium: Organic solvents such as ethanol, acetone, toluene, etc. are widely used in electronic appliances, chemical coatings and other fields. Thermal fuses may be exposed to various organic solvents when used in these fields. The corrosion effect of organic solvents on thermal fuses is mainly through dissolving and swelling certain components in the thermal fuse, destroying its molecular structure and physical properties. For example, some thermal fuse materials may dissolve to a certain extent in ethanol, causing their surface to become rough and their strength to decrease. Polar organic solvents such as acetone may have a strong extraction effect on additives, plasticizers and other components in the thermal fuse, affecting the overall performance of the thermal fuse. Therefore, when evaluating the chemical corrosion resistance of thermal fuses in an organic solvent environment, it is necessary to comprehensively consider factors such as the type, polarity, and molecular weight of the solvent, and select an organic solvent that is representative and in line with actual usage as the test medium.

5. Actual case analysis of the chemical corrosion resistance test of thermal fuses
(I) Case background
A thermal fuse manufacturer mainly produces thermal fuse products for the assembly of automotive interior parts. Since automotive interior parts may be exposed to various cleaners, disinfectants, and chemicals that passengers may bring in during use, high requirements are placed on the chemical corrosion resistance of thermal fuses. In order to meet the quality standards and market needs of international automobile manufacturers, the company decided to conduct chemical corrosion resistance tests on the thermal fuses it produced and improve the product formula to improve its corrosion resistance.
(II) Test plan
Based on the actual use environment of thermal fuses and relevant standard requirements, the following test plan was formulated:
Test samples: 10 batches of thermal fuse samples were randomly selected from the production line, and 5 samples were selected from each batch for testing to ensure the representativeness and reliability of the test results.
Test solution: Several common automotive interior cleaners and disinfectants were selected, including alkaline cleaner A with a pH value of 12.5, acidic cleaner B with a pH value of 1.5, and disinfectant C containing 75% ethanol. These solutions represent the alkaline, acidic and organic solvent environments that the thermal fuse may be exposed to in actual use.
Test method: The test is carried out by immersion method combined with weight loss method. The thermal fuse samples are immersed in the above three test solutions respectively, and 3 parallel samples are set for each solution. The immersion temperature is 25℃±2℃, and the immersion time is 24 hours, 72 hours and 168 hours respectively. At each immersion time point, the sample is taken out, rinsed with distilled water, weighed after drying, and the mass loss rate is calculated. At the same time, the microscopic morphology changes of the sample surface are observed by scanning electron microscopy (SEM) to analyze the morphology and degree of corrosion.
Evaluation index: The mass loss rate and surface microscopic morphology changes of the thermal fuse in different test solutions are used as the main evaluation indicators. The smaller the mass loss rate and the smaller the surface microscopic morphology changes, the better the chemical corrosion resistance of the thermal fuse.
(III) Test results and analysis
Mass loss rate: After testing, it was found that in alkaline cleaner A, the mass loss rate of the hot fuse sample gradually increased with time, but at 168 hours, the mass loss rate was only 0.32%, indicating that the hot fuse has good corrosion resistance in alkaline environment. In acidic cleaner B, the mass loss rate of the hot fuse was significantly higher, reaching 1.85% at 24 hours, and continued to rise with time, reaching 4.78% at 168 hours, indicating that the hot fuse is susceptible to corrosion in an acidic environment. In disinfectant C containing ethanol, the mass loss rate was relatively low, at 0.78% at 168 hours, indicating that the hot fuse has a certain tolerance to organic solvents.
Surface micromorphology: SEM observation showed that the surface of the hot fuse after soaking in alkaline cleaner A was relatively smooth, with only a few microscopic scratches and corrosion marks, which is consistent with the lower mass loss rate. After being immersed in acidic cleaner B, obvious corrosion pits and grooves appeared on the surface of the sample, and as the immersion time increased, the depth and distribution range of the corrosion pits continued to expand, indicating that the acidic environment caused serious corrosion damage to the surface of the thermal fuse. Although there were some subtle rough areas on the surface of the sample after being immersed in disinfectant C, the overall surface structure remained basically intact, and no obvious corrosion phenomenon occurred.
(IV) Improvement measures and effect verification
Improvement measures: According to the test results, the company improved its product formula to address the problem of insufficient corrosion resistance of the thermal fuse in an acidic environment. An acid-resistant additive was added to the raw materials of the thermal fuse, and the production process parameters were optimized to improve the density and chemical stability of the thermal fuse.
Effect verification: The improved thermal fuse was tested for chemical corrosion resistance again according to the same test scheme. The results showed that in acidic cleaner B, the mass loss rate of the improved thermal fuse sample was reduced to 1.23% at 168 hours, and the number and depth of surface corrosion pits were also significantly reduced. This shows that through the improvement of the formula, the chemical corrosion resistance of the thermal fuse has been effectively improved, which can better meet the actual use requirements of the assembly of automotive interior parts. At the same time, in alkaline cleaner A and disinfectant C, the corrosion resistance of the improved thermal fuse also maintained the original good level.

6. Future development direction of thermal fuse chemical corrosion resistance test
(I) Multi-factor coupling test
With the continuous expansion and complexity of the application field of thermal fuses, the single-factor chemical corrosion resistance test can no longer fully meet the actual needs. Future testing research will pay more attention to multi-factor coupling testing, that is, considering the combined effects of multiple factors such as temperature, humidity, chemical medium type and concentration, and mechanical stress on the chemical corrosion resistance of thermal fuses. For example, in the test simulating the environment in the engine compartment of a car, the thermal fuse not only has to withstand high temperature, high humidity and erosion of various chemical media, but also mechanical stress such as vibration and stretching. By carrying out multi-factor coupling testing, the corrosion resistance of the thermal fuse under actual complex working conditions can be more realistically reflected, providing a more accurate basis for product design and application.
(II) Research and development of accelerated test methods
In order to shorten the test cycle and improve the test efficiency, the research and development of accelerated test methods will become an important development direction for the test of chemical corrosion resistance of thermal fuses. Accelerated test methods accelerate the corrosion reaction process of thermal fuses by adopting higher test temperatures, stronger chemical medium corrosiveness, more frequent medium replacement, etc., so that they can show corrosion behavior and performance changes similar to those in actual long-term use in a shorter period of time. However, when developing accelerated test methods, it is necessary to conduct in-depth research on the mechanism and kinetics of corrosion reactions to ensure that the accelerated test results have good correlation and comparability with actual use conditions. At the same time, a reasonable acceleration factor model is established to accurately predict the corrosion resistance life of thermal fuses in actual environments based on the accelerated test results.
(III) In-depth application of microscopic analysis technology
With the help of advanced microscopic analysis technologies such as atomic force microscopy (AFM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), etc., in-depth research on the microstructure and composition changes of thermal fuses during chemical corrosion is of great significance for revealing their chemical corrosion resistance mechanism and developing high-performance thermal fuse materials. In future research, the application of these microscopic analysis technologies will be further strengthened. By analyzing the atomic structure, chemical bonding state, element distribution and other microscopic information on the surface and interface of the thermal fuse, we can gain a deeper understanding of the initial stage, propagation process and failure mechanism of the corrosion reaction. This will help to propose more effective methods and strategies to improve the chemical corrosion resistance of the thermal fuse from the perspective of material design and modification.
(IV) Development of intelligent testing system
With the continuous advancement of science and technology, the development of intelligent testing systems will bring new changes to the chemical corrosion resistance test of thermal fuses. Intelligent testing systems can realize automatic control, real-time monitoring and data acquisition and analysis of the test process. For example, through sensor technology, parameters such as temperature, humidity, and chemical medium concentration in the test environment can be monitored in real time, and the test conditions can be automatically adjusted according to the preset test procedures to ensure the stability and accuracy of the test process. At the same time, the data processing software is used to quickly analyze and process the large amount of test data collected, generate intuitive test reports and charts, and provide researchers and technicians with timely and accurate test result feedback. In addition, the intelligent testing system can also realize remote monitoring and operation, improving the convenience and flexibility of testing work.
(V) Close integration with practical applications
In the future, the chemical corrosion resistance test of thermal fuses will be more closely integrated with the actual application needs, and targeted testing and research will be carried out to solve practical engineering problems. In the design process of the test plan, the specific working conditions, service life and expected performance requirements of thermal fuses in different application fields will be fully considered to formulate more scientific, reasonable and practical testing standards and methods. At the same time, strengthen cooperation with thermal fuse manufacturers, feedback the test results to the enterprises in a timely manner, guide the enterprises to improve products and control quality, promote the technological innovation and performance improvement of thermal fuse products, and finally meet the market demand for high-quality thermal fuse products.
