In order to reduce using amount of caustic soda,synthesis conditions should be controlled to ensure Shore hardness (A) of product 56～58,elongation rate 650%～750%,tensile strength 10.
影响氯化聚乙烯生产中烧碱耗量的因素包括 :产品的表观密度、筛余物、邵氏硬度、伸长率、抗拉强度和原料聚乙烯的颗粒形态。
Results show absolute alkali consumption increases while temperature goes up and solid/ liquid ratio decreases.
监测了反应前后碱液浓度的变化 ,计算了各个条件下的绝对碱耗量。
