锆-铝-钛鞣山羊服装革工艺板块的组装与评价

Assembly and evaluation of technological plate of goat garment leather by Zr- Al- Ti complex tanning agent

研究对锆-铝-钛配合鞣剂鞣山羊服装革的工艺板块进行设计与组装,并运用功能性、生态性、经济性等指标,对其工艺板块的运行进行了评价。研究表明:采用1%改性戊二醛进行预处理,采用20%锆-铝-钛配合鞣剂进行鞣制,并采用2%丙烯酸树脂+3%醛类鞣剂+4%乙烯基共聚物树脂类鞣剂这一复鞣方案进行复鞣,所得的成革收缩温度大于90℃,鞣制废液的BOD5/COD为0.256,其它物理-机械性符合行业标准,感官性能与铬鞣革相当。

The technological plate of goat garment leather by Zr - Al - Ti complex tanning agent was designed and assembled. Then the plate was evaluated with functionality, ecology and economy as indexes. The studies show that the processes which using 1% modified glutaraldehyde for pretreatment, 20% Zr - Al - Ti complex tanning agent for tanning, and 2% acrylic resin, 3% al- dehyde tanning agent and 4% vinyl copolymer resin for retanning are adopted, the shrinkage temperature of tanned leather is over 90~C, the BODs/COD of tanning effluent is 0. 256. The physical and mechanical properties can meet the industrial standards, and the sensory properties are comparable to those of chrome tanned leather.
