摘要
针对常规浸酸铬鞣方法中的一些缺陷 ,在常规铬鞣剂的合成基础上 ,对其作进一步改性而制备出不浸酸铬鞣剂 ,并对铬鞣剂的性能进行了表征。通过试验证明了用该铬鞣剂进行不浸酸铬鞣 ,可以明显提高铬鞣剂吸收率 ,使铬鞣剂在革内分布更均匀 ;蓝革厚度增加且面积增大 ;减少铬污染 ,杜绝铬鞣引起的氯离子的污染 ;有效改善革的松面情况 ;简化制革工艺 。
Chrome tanning agent without pickling is prepared, and its properties are studied. Through tanning experiments some characteristics of the chromitan such as high exhaustion of chrome, decrease of loose grain and increase of the thickness and area of leather are found. The tannage with the new chromitan can not only decrease the pollution of chrome and chloride in sewage, but also reduce the cost of leather manufacturing and simplify the tanning process.
