工业副产石膏晶须研究进展

STUDY ON THE PROGRESS OF THE INDUSTRIAL BY-PRODUCT GYPSUM WHISKER

工业副产石膏是石膏可再生资源,推广高附加值石膏晶须的利用是循环利用工业副产石膏有效途径之一。主要介绍了石膏晶须的制备方法,利用添加剂改善石膏晶须的结晶速度、晶体形貌和在水中的稳定状况。同时综述了石膏晶须在高分子材料、建筑材料和造纸领域应用状况,展望今后的研究方向。

Industrial by-product gypsum was a renewable resourse of gypsum; promotion of using high value-added gypsum whisker was one of the effective ways to recycle industrial by-product gypsum.This paper mainly discussed the preparation of industrial by-product gypsum whisker,and the use of additives to improve the crystallization rate of gypsum whisker,crystal morphology and stability in water.At last it was introduced its application status in the fields of polymer material,building material and papermaking,and the researching direction in the future was given.
