【摘要】 研究了制碱盐泥用于聚氯乙烯（ＰＶＣ）填料的可行性，讨论了盐泥填充ＰＶＣ制品的多种性能。实验结果表明：盐泥填充ＰＶＣ材料的加工性能良好，力学及物理性能与碳酸钙填充ＰＶＣ相近，可以用做ＰＶＣ的填料。更多还原

【Abstract】 Feasibility was carried out of salt sludge of sodium production as filler for PVC.A variety of properties of PVC rigid products were discussed.The experiment results showed that processability and heat resisting of the PVC products filled with salt sludge were good.Its mechanical properties was close to that of calcium carbonate filled PVC.Salt sludge can be used as PVC filler to substitute for calcium carbonate.更多还原
