皮化生产中盐析酸水在制革浸酸中的应用工艺研究

STUDY ON THE TECHNOLOGY OF THE SALTING-OUT ACID LIQUID PRODUCED BY THE MANUFACTURE OF CHEMICAL MATERIALS TO THE PICKING PROCESS IN LEATHER MAKING

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.
