Abstract Having refered to a great deal of preference on foreign popular less chrome pollution tannage methods, the authors determined the technology of feasible less chrome pollution tannage through several experiments. 本文作者查阅了国外常见的低铬污染鞣制法的文献,在此基础上,通过试验确定了切实可行的使用FK-Ⅱ柔软型聚合物鞣剂预鞣的低铬污染鞣制工艺。
Chrome tannage that can make excellent leather products is the most important tanning system in the leather industry so that there have not other tanning agents better than chrome agent for more than 100 years. 100多年来,Cr鞣法在制革工业中一直是最重要的鞣法之因是Cr鞣剂鞣革的性能是其它鞣剂鞣革无法比拟的。
A new kind of chrome tanning agent, C-2000 tanning agent, was specially made for the chrome tannage without pickling. 本文所试验的C-2000铬鞣剂是一种专为浸酸鞣制而研制的新型铬鞣剂,它适合于各种鞋面革在软化后直接进行鞣制。

To understand the tanning mechanism of no-pickling chrome tannage, the variation of pH value and ultraviolet spectra of tanning liquor during the chrome tanning without pickling were studied. Also, the pH value and phase transition temperature in different layer of leather were measured in the experiment. 研究了在不浸酸鞣制过程中,鞣液的pH值、紫外吸收以及皮内各层的pH值和相变温度的变化规律,以进一步认识不浸酸铬鞣剂的鞣制机理。
