对低温法生产HPVC树脂的生产工艺进行了改进，解决了釜内外温差小，传热困难，反应温度难以控制，反应时间长，生产成本高等问题。改进后反应时间缩短为7～8h，产品质量稳定。
對低溫法生產HPVC樹脂的生產工藝進行瞭改進，解決瞭釜內外溫差小，傳熱睏難，反應溫度難以控製，反應時間長，生產成本高等問題。改進後反應時間縮短為7～8h，產品質量穩定。
대저온법생산HPVC수지적생산공예진행료개진，해결료부내외온차소，전열곤난，반응온도난이공제，반응시간장，생산성본고등문제。개진후반응시간축단위7～8h，산품질량은정。
The production process of HPVC resins by low temperature method was improved, and the problems of small temperaturc diffcrcnce between the inside and outside of polymerizers, difficult hcat transfer, uncontrollable reaction tempcraturc, long rcaction time and high production cost were solved. Aftcr improvement, the reaction time could be shortened to 7-8 hours, and the product quality was stable.
