摘　　要：提出了钠法漂粉精工艺的分类方法。从氯化钠与目标晶体水合次氢酸钙间的关系、母液循环等角度分析了钠法漂粉精工艺的反应结晶原理。综述了国内外主要钠法漂粉精工艺,指出了各工艺的优缺点。最后分析了国内钠法漂粉精工艺发展中存在的问题,提出了发展和改进的建议。The sodium - process bleaching power classification was brought forward. Through the relationship between sodium chloride and target crystal： calcium hypochlorite hydrate, the recycle of mother liquid, the principle of reactive crystallization of sodium - process bleaching power was analyzed. The main processes of sodiumprocess bleaching power at home and abroad were summarized, and the advantages and disadvantages of these processes were pointed out. The problems of sodium - process bleaching power for home were analyzed, and the suggestions on sodium - process bleaching power were put forward.
