Welcome to inquire! Contact: Zhao Shuang. PVC (full name Polyvinylchlorid), the main ingredients of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table uppermost layer mask is painted PVC pipe fittings prices, the main ingredient in the middle of polyvinyl chloride, the lowest layer is coated with an adhesive backing. the nature of the application of PVC pipe pvc pipe is a vacuum plastic film PVC pipe fittings manufacturers, packaging for all types of panel surface, it is also known decorative film, with film, used building materials, packaging, pharmaceuticals, and many other industries. Building materials industry accounted for the largest proportion, 60 percent, followed by the packaging industry, PVC pipe fittings, as well as a number of other small-scale industry applications. PVC pipe is divided into two kinds of PVC water supply and drainage, water supply and drainage for municipal and industrial water supply and drainage, civil drainage, irrigation, watering and other vegetation. PVC heat stability and lightfastness is poor. At 140 ℃ decomposition of hydrogen chloride at the beginning, with the number of plasticizer content of the occurrence of adverse reactions. In addition, the pigment affect the supply of PVC pipe fittings for PVC, reflected in the reaction of the pigment and the pigment itself whether migration resistance, heat resistance occurs with other components of the composition of PVC and PVC products. Therefore, the colored PVC, considering the resin used and the characteristics of the relevant additive combination pigment characteristics. When selecting a colorant should be noted that the following questions. Stability of the coloring agent may induce the degradation of some of the ingredients of the resin. Such as iron ions and zinc ions are PVC resin catalyst degradation reactions. Therefore, iron oxide (red, yellow, brown and black), or zinc oxide pigment, zinc sulfide, and lithopone, white pigments can reduce the thermal stability of the PVC resin. Some colorants may effect the occurrence of degradation products of PVC resin. Based pigments such as ultramarine poor acid resistance, so in PVC coloring process, will be produced by the decomposition of hydrogen chloride and PVC lose their color and interact.
