摘要
基于锆-铝-钛配合鞣剂的少铬鞣制全封闭式循环技术,是将鞣制系统形成一个全封闭式的循环体系,在减少铬鞣剂用量的前提下,实现废鞣液的循环利用,消除重金属铬的污染;该技术不增加新的化学材料,不会带来2次污染,投资少,操作简单;锆-铝-钛配合鞣剂和铬盐的用量较少,2种鞣剂的总用量低于8%。将该系统用于黄牛鞋面革的鞣制,鞣得的坯革革身颜色浅淡,耐水洗性能良好,染色性能良好;生产的成革收缩温度超过90℃,成革物理-机械性能基本符合鞋面革的要求。
This totally enclosed circulation technique was a kind of less-chrome tanning system based on Zr-Al-Ti tanning agent. The recycling of waste tanning liquid as well as heavy metal chromium pollution eliminated could be came true, on the premise that reduced chrome complex was usad. New chemical materials would be not added without secondary pollution when the new technology was employed. It is a good method with less investment and simple operation. The dosage of Zr-Al-Ti tanning agent and the chromic salt was less and total amount of two kinds tanning agent was lower than 8%. The system was used for cattle shoe upper leather tanning, lightness color and good performance of washable and dyeing of the crust is obtained. The shrinkage temperature of finished leather is up to 90℃, and of which physical and mechanical properties is basically in agreement with the requirements of the shoe upper leather.
