铬鞣的

The high chrome tanned leather fibre and natural rubber content give it excellent strength, while the right percentage of vegetable tanned leather fibre aids the chamfering of edges.

高含量的铬鞣皮屑纤维和天然乳胶使它的强度增大，而适当比例的植鞣皮屑纤维更使它容易做多角度的切割。

Its synthesis and structure,its interaction with collagen and chromium complexes,as well as its effect on chrome tanning properties,have been studied.

There exist some unassailable problems in traditional chrome tanning, such as low exhaustion of chrome, salt pollution from pickling, and time-consuming process, etc.

传统浸酸铬鞣存在着一些不容忽视的问题，如：铬的吸收率低，浸酸时带来的盐污染，鞣制周期长等。

The grain size and Zeta potential of gelatin reacting with no-pickling chrome tanning solution on thebase of gelatin was investigated.

以明胶为基础，研究了明胶溶液与不浸酸铬鞣剂作用后明胶体系的粒径、Zeta电位变化规律。

Two main ways in industry traditionally were used to prepare chrome tanning agents: one is using sugar as reducing agent, another is using sulfur dioxide.

工业上制备铬鞣剂的传统方法有糖和二氧化硫两种还原方法。
