When using nylon tie, do you think it will become brittle under low temperature working conditions or after winter? This is normal. What the hell happened?
The main component of nylon tie is plastic, and plastic is a kind of polymer. Macromolecules are characterized by slower speed when moving at low temperature and faster speed when moving at high temperature. In winter or low temperature, the thermal motion of molecules is very slow. When the nylon tie is subjected to external force, the cushion block will deform. Because the molecular thermal movement is slow, the external force is not easy to transfer (average thermal stress) or consume (friction of molecular structure chain), so it is easy to cause internal stress. When the thermal stress reaches a certain level, the macromolecules will break and lead to cracks. Cracks will cause internal stress and diffusion, and nylon ties will break.
How to deal with such a problem?
The first method is to add small molecular water materials in the production of nylon ties. In motion, the force transfer effect of the molecular structure of elastomer material is practical, but this method is too high
Therefore, it is only used in some unique manufacturing industries, such as high-tech scientific research of high-tech materials and safety fire protection system software, which must work in a safe natural environment.
In the second way, when applied to nylon ties in people's daily life under low temperature conditions, people can first conduct simple heating, such as covering the heat by hand or short-term heating by air heater.
The third method is to apply the nylon connection process as smoothly as possible so that the force transfer between plastic molecular structures is symmetrical.
Conclusion: these three methods are the most mainstream products at this stage. They are the most reasonable way to reasonably reduce accidental wear in nylon tie applications. In fact, it is not only suitable for nylon ties, but also all plastic crafts are universal.
