摘要
制革中性盐的排放是一个难以解决的问题。反映在废水的污染指标为TDS和Cl-,近40%源于生皮的防腐。食盐的价廉和防腐操作的简便自然是制革工业最佳的选择,然而少盐和无盐的防腐研究也从未停止过。本文再一次综述一些原料皮防腐方法同时编译介绍了一种硼酸-食盐防腐的研究方法与结果。
It is inevitable for leather processes to exclude neutral salts, about 40% of TDS and Cl^- in waste water derived from the raw hide preservation. Although common salt in cheap and process in convenient is the best of preservation techniques, the work reducing or removing common salt in raw hide preservation are never stopped. Here some raw hide preservation techniques were summarized once more, and at the same time a kind of preservation work using boracic acid-NaCl were introduced.
