PVC膜加工稳定剂的选择研究与应用

Selection and application of stabilizer for PVC film processing

PVC树脂因为其自身构型的问题,键位不稳定且耐热不足,在受热的环境下极易发生分解从而降解,造成其存在晶点、变质等情形。因此采用加入稳定剂,通过阻隔分子间的反应、形成稳定的分子结构、减少不饱和键的增长等原理有效防止PVC树脂发生降解,提升耐温性,保证产品质量。

Due to the problems of its own configuration,unstable key position and insufficient heat resistance,PVC resin is easy to decompose and degrade under the heated environment,resulting in the existence of crystal points and deterioration. Therefore,stabilizer is often added to effectively prevent the degradation of PVC resin,improve the temperature resistance and ensure the product quality by blocking the reaction between molecules,forming a stable molecular structure,reducing the growth of unsaturated bonds and other principles.
