基于酶制剂的猪皮前处理技术(Ⅰ)-猪皮前处理工艺板块的设计与优化

采用制革工艺板块模式 ,将猪皮前处理划分为酶脱脂工艺板块、酶 -碱结合脱毛工艺板块以及酶软化等 3个工艺板块 ,并对其逐一进行了研究优化 ,最后将已优化的工艺板块组装、运行 ,构建出基于酶制剂的猪皮前处理定型工艺。经大生产验证结果表明 :成革手感好 ,质量、得革率也得到大幅度提高。制革综合废水中有害物质的量大大降低 ,减轻了猪皮制革的污染。

The technology of wet process of pig skin based on enzymes preperation-design and optimization for the process plates of wet process

With the application of the model of process plate of leather-making,the wet process was divided into three process plates,such as, the process plate of enzymatic degreasing, the process plate of enzymatic unhairing and enzymatic bating, and then each of these process plates is optimized, finally, the process plates optimized are assembled and run, the stereotyped technology of wet process of pig skin based on enzyme preparation was set up. The results through testing and verifying, by bath production showed that the resultant leather possess of better quality, good handle and higher yield of leather. The amount of hazardous materials in integrated waste water of leather-making were reduced greatly, so the pollution of leather-making with pig skin were cut down to great extent.
