摘　　要：将目前机械化蜡染厂采用的气浮回收蜡和我们实验室使用的热水脱蜡法、有机溶剂萃取回收法、水基表面活性剂乳液回收法及干法除蜡等方法比较,结果表明:热水脱蜡法是最适合机械化蜡染厂进行蜡的回收.回收成本低、回收率高达95%以上、回收蜡可直接用于蜡染,并且脱蜡废水大幅减少,可为污染严重的蜡染生产企业解决环保问题.The air flotation method of wax recovery commonly used in the actual mechanized wax printing mills was compared with the methods we used in our labs, such as hot water dewaxing, org. solvent extn., aq. surfactant recovery and dry dewaxing. The results showed that the hot water dewaxing was the most suitable method for wax recovery in mechanized mills because of low cost, high recovery of over 95%, direct reuse of the recovered wax, and substantial reduction of wastewater, which helps the gravely pollutant mills with finding the resolution of environment problems.
