At present, in the finishing process, professional institutions have conducted research on hot melt. The test is used to obtain the best automatic processing effect, so the effect is good heat resistance and stability, the mechanical application associated with the passage, and the relationship between the fatigue resistance and the node of the hot melt wire, by the study of the heat-resistant finishing process of impregnated molten sulfur, so that ordinary hook belt contains the temperature hot melt wire in floor fabrics and braids.
After multiple attachment points and weft yarn interweaving, when the hot melt wire is subjected to multiple fatigue tests, it is proved by practice that as the number of connection points, the fatigue strength of the hot melt wire first decreases and then increases. The regression equation can predict the rate of fatigue resistance of hot melt wires with different welding temperatures, which has important guiding significance in the study of fatigue resistance of hot melt wires. The establishment of the mechanical model is through all the heat, the theoretical calculation formula of the resistance of the hot melt wire separation, and the density of the connection and hook of the integrated hot melt wire is obtained.
Through actual measurement, users can use the calculation formula to predict and calculate the application strength of the temperature hot fuse, the application strength of the hot fuse and the percentage deviation correction factor when it is less than 3%, according to the point coil model, the mechanical resistance model, the thermal cutting is first used with the formula to calculate the shear strength of the hot fuse of a single hook, and the joining speed and the density of the hook are combined, and the resistance is obtained by cutting the hot fuse to complete the theoretical calculation. The formula is used to calculate the shear strength of the hot fuse final temperature obtained by actual measurement and correction coefficient, and can be used to predict and calculate the shear strength of the hot fuse at temperature, composite non-corrugated flexible, currently through the following method involving flexibility composite non-corrugated, after the material of the structure is treated by dipping, the PVC sheet is double-sided welded, and then the surface is cooled.
