铬革

The results have indicated that acid bating fits to bating of sheepskins especially for sheepskin's loose structure because of more alleviate action of acid enzymes, and acid bating has little loss of hide substance.

结果表明，酸性酶软化作用温和、深透，对胶原损害小，特别适合于组织结构疏松的绵羊皮生产。酶制剂用于绵羊服装革鞣前准备其它关键工序，可减少硫化物、表面活性剂等有害物质的用量，提高铬结合，减少作用时间，提高面积得率和成革质量。

In this paper,the various methods of reclaiming chrome and collagen from chrome effluent and chrome-tanned leather sc...
