If possible, there is no non-degradable material. PVC material is a kind of plastic decorative material, which is the abbreviation of PVC material. PVC (polyvinyl chloride) resin is a thermoplastic polymer polymerized from vinyl chloride monomer (VCM).
Pvc paste resin is a special kind of pvc with fine white powder, which is mainly used to make artificial leather, screen window, automobile glue, wallpaper, floor coil and toys. In the production process, the moisture content in pvc paste resin is an important measurement index, which has important guiding significance for production.
The national standard GB-T29 14-20008 "Determination of volatiles (including water) of plastic vinyl chloride homopolymer copolymer resin" mainly determines the moisture and volatile organic impurities contained in the resin itself. These components will become bubbles in the product during processing, which will affect the strength, appearance and other properties of the product. It is an important index to measure the quality of paste resin products. However, because the national standard analysis method adopts the oven method, and the paste resin has the characteristics of small particles, light weight and static electricity, environmental conditions and equipment conditions have great influence on the analysis results, and the accuracy and reliability of the analysis results are not high.
