UPVC Steel Epoxy Coated Pressure Water Supply Fittings Leak Repairing Coupling
PVC is completely non-toxic and tasteless. It does not cause any irritation to human skin or respiratory system. For those who are allergic to wood and paint, furniture or kitchen utensils packed with PVC film are very suitable. By using a PVC film as a decorative film, one can largely avoid the use of medium-density boards, particle boards, plywood and fiberboards, reducing the amount of wood used, thereby reducing damage to forests and the environment.
The softening point of the polyvinyl chloride resin is low, about 75-80 ° C, and the embrittlement temperature is lower than -50 ~ -60 ° C. The long-term use temperature of most products should not exceed 55 ° C, and the special formula can reach 90 ° C. If the polyvinyl chloride resin is purely a head-like junction, it is afraid of a linear structure, and there is no branching or unsaturated bond inside. Although the C-Cl bond energy is relatively small, the stability of the polyvinyl chloride resin should be relatively high. . However, even if the polyvinyl chloride resin has a high purity, hydrogen chloride gas will start to escape at a temperature of 100 ° C or higher or ultraviolet radiation. It indicates that there are sharp groups or unstable structures in its molecular structure. The longer the time, the more degradation, the higher the temperature, the faster the degradation rate, and the faster the degradation in the presence of oxygen or air.
