皮革真空鞣制技术的试验研究

Application of Vacuum Technology in Leather Cleansing and Tanning

为了解决皮革鞣制污染严重、工作时间长等技术问题,利用真空机制的脱气、膨松、浸渍、脱水等作用,实施与真空状态相适应的工艺条件进行皮革鞣制处理。论述了真空鞣制的机理和特点,研制了皮革真空转鼓,进行了真空鞣制清洁加工技术的试验研究,分析了真空鞣制过程中的主要影响因素。结果表明:在全面提高皮革鞣制质量的前提下,工作时间大大缩短,废液排放量减少50%以上,为制革业污染问题提供了解决途径。

Vacuum technology has been successfully applied to cleansing and tanning of leather.A dedicated vacuum system was designed and constructed.The vacuum system design considerations and the operating conditions of the cleansing and tanning in various procedures,including degassing,bulking,impregnating,dehydrating of leather,were discussed.The influence of major factors,such as the pressure,leather temperature,rotation of the vacuum drum,and chemical compositions,on leather quality was studied.The results show ...
