摘　　要：介绍了用离心沉降对紫胶脱蜡和四氯化碳萃取精制紫胶蜡的研究过程和结果 .在大量试验的基础上 ,证明经过脱蜡后的紫胶含蜡低 ,符合GB81 39～ 81 47- 1 987标准 ,其耐热性和附着力增强 ,耐腐蚀性提高 ,颜色得到改善 .另外 ,用四氯化碳回收紫胶蜡 .因此 。The research is made on dewaxing shellac by centrifugal subside and refining shellac-wax by Carbon tetrachloride extraction. The result shows that shellac contains low wax after dewaxing according to ISO standard, the heat resistance and adhesive force of shellac are enhanced; the corrosion resistance is increased; and the color is improved. In addition, the Carbon tetrachloride extraction is used to retrieve and refine shellac-wax. So an economical and speedy way to dewax shellac and refine shellac-wax is found.
