摘要
本文利用皮革化工厂硫酸化生产中的盐析酸水进行制革浸酸,经过中试及工业化应用表明,盐析酸水用于漫酸可简化制革工艺,制得皮革成品质量稳定。盐析酸水的综合再用不仅具有一定的经济效益,更重要的是大大地减轻了因直接排放而造成的对环境的严重污染,从而体现出明显的社会效益。
In this article, the salting-out acid liquid, resulted from the sulfating process in leather chemical plant, is applied to the picklimg process in leather making. The experiment on a midium scale and industrial appliation show that this picking method can simplity leather making technology, and the quality of the finished product is consystent. The comprehensive reuse of salting-out acid liquid not only is economical. but also lightens the environmental pollution by salting -out effluent.
