How to prevent static electricity problems during the production of polyester hot melt yarn?
In the production process of polyester hot melt yarn, static electricity is an issue that needs special attention, because it not only affects production efficiency, but also may threaten product quality and operator safety. The following are some effective measures that can help prevent the occurrence of static electricity problems: c

1. Control environmental humidity
Maintaining appropriate environmental humidity is an effective way to reduce static electricity problems. In a dry environment, static electricity is easy to accumulate and discharge. By increasing indoor humidity, static electricity problems can be effectively alleviated

2. Use antistatic materials
During the production process, the use of antistatic materials can reduce the generation of static electricity. For example, antistatic agents can be added to the surface of polyester hot melt yarn. These antistatic agents can be conductive carbon powder, antistatic agents, etc., to reduce the resistivity of the material, thereby reducing static electricity accumulation

3. Grounding measures
Proper grounding of equipment, tools and personnel is a key step in preventing static electricity accumulation and discharge. Use grounding wires to safely guide static electricity to the ground and ensure a good grounding connection. Using anti-static equipment and materials can reduce the generation and accumulation of static electricity

4. Use anti-static hot melt adhesive
In the production process of polyester hot melt wire, anti-static hot melt adhesive can be used. This hot melt adhesive contains hot melt adhesive and conductive powder, which can form a conductive coating on the insulating substrate, reduce surface resistance, and play an anti-static role

5. Use EMI paint
Spray EMI paint on the inside of the device shell. This paint is conductive and can be regarded as a metal shielding layer, which guides static electricity on the shell, and then connects the shell to the ground of the PCB to guide static electricity away from the ground, effectively preventing static electricity

6. Increase material thickness or air gap distance
By increasing the distance between the shell and the circuit board, or by increasing the distance of the shell air gap through some equivalent methods, the energy intensity of ESD can be avoided or greatly reduced

7. Avoid metal decorations
Avoid using metal decorations on the equipment, because they may cause unexpected static electricity problems and require special attention

8. Human body static protection
People working in static hazardous places should wear anti-static clothing, shoes, and anti-static gloves when necessary. In addition, safe and effective local electrostatic protection measures, such as wrist straps, can be used to prevent the occurrence of electrostatic hazards

9. Process equipment design
In the design of process equipment, electrostatic conductors or electrostatic subconductors should be used, and electrostatic non-conductors should be avoided. For highly charged materials, it is advisable to install an electrostatic buffer at an appropriate position close to the discharge port

10. Regular inspection and maintenance
Regularly inspect the effectiveness of the electrostatic grounding system and anti-static measures of the equipment to ensure that they can work properly. Any problems found should be maintained and repaired in a timely manner.

Through the above measures, static electricity problems can be effectively prevented during the production process of polyester hot melt yarn, ensuring the smooth progress of production and the safety of operators.

What are the common electrostatic hazards in the production process of polyester hot-melt wire?

The electrostatic hazards that may be encountered in the production process of polyester hot-melt wire mainly include the following aspects:

1. Fire and explosion risks
Static electricity may cause fires and explosions in some cases. Especially in equipment and pipelines carrying flammable gases or liquids, sparks generated by static electricity may cause explosions. In the production process of polyester hot-melt wire, due to the involvement of chemical substances and high-speed machinery, the accumulation of static electricity may reach the level of causing fire or explosion, so special vigilance is required.

2. Electric shock risk
When the human body carries static electricity, touching a charged object may cause an electric shock. Although it is usually a mild electric shock, it may even cause life-threatening danger to certain specific groups of people, such as heart patients. In a production environment, workers may suffer electric shocks due to electrostatic discharge, affecting work safety.

3. Risk of damaging electronic equipment
Electrostatic charge can cause damage to electronic components, such as semiconductor devices or integrated circuit chips. This may cause equipment failure and cause production line interruptions and quality problems. In the production line of polyester hot-melt wire, static electricity may cause damage to sensitive electronic control equipment, affecting production efficiency and product quality.

4. Risk of harming the human body
The release of static electricity can cause harm to the human body. For example, when rapidly moving static electricity impacts the human body, it may cause burns or skin irritation. During the production process, operators may suffer personal injury due to static electricity discharge.

5. Hindering production and reducing product quality
The harm of static electricity to industrial production is mainly manifested in hindering production or reducing product quality. In the textile industry and fiber processing industries, especially in the production and processing of synthetic fibers such as polyester and acrylic, the problem of static electricity is more prominent. For example, during the spinning process, each strand of silk must be squeezed out of a small hole with a diameter of tens of microns, which will generate strong static electricity. Due to the effect of static electricity, the silk will float, stick, tangle, etc., which will hinder normal production.

6. Affecting winding and adsorbing dust
During the process of weaving, printing and dyeing, due to the adsorption of static electricity, dust may be adsorbed, reducing product quality, and even affecting winding, making the winding loose. This not only affects the appearance quality of the product, but also may affect the performance of the product.

7. Material flying and environmental pollution
When powder is bagged, the powder flies everywhere due to the electrostatic repulsion, which not only causes powder loss but also pollutes the environment. In the production process of polyester hot-melt yarn, if the material is not handled properly, it may cause the material to fly, affecting the working environment and personnel health.

In summary, the electrostatic hazards in the production process of polyester hot-melt yarn involve many aspects, from safe production to product quality, to the environment and human health. Therefore, it is crucial to take effective anti-static measures.
