摘　　要：磷石膏微粉经过表面改性后,可以代替碳酸钙作为聚氯乙烯(PVC)产品的填料,但加工稳定性差、不能连续化生产是限制PVC/磷石膏微粉产品产业化、规模化的核心关键问题之一。概述磷石膏微粉制备工艺、PVC加工热稳定体系及其作用机制。After surface modification, phosphogypsum micro-powder can be used as filler for PVC products instead of calcium carbonate. However, poor processing stability and non continuous production is one of the key issues limiting the industrialization and scale of PVC/phosphogypsum micro-powder products. The preparing process of phosphogypsum micro-powder, the thermal stability system of PVC processing and its mechanism of action are summarized.
