铬鞣革

The drying process of chrome liquor was studied. The structure and property of chrome complex reducing by alcohol were analysed and tokened by many present well-rounded separation and analysis methods such as IR, UV-Vis Spectrum, IEC and pH potentiometry. Application tests of chrome tanning agents were conducted and tanning methods of tanning at high pH were studied. A systematic study was conducted on high alkalinity chrome tanning agents application in leather making process and possibility of clean chrome tanning was discussed.

According to the practical needs of chrome-free tannage, titanium is abundant in nature, easily obtainable and ecologically friendly, titanium tannage can produce a leather with similar performance to chrome-tanned leather, so the research of titanium tannage to alternative chrome tannage was established as the research direction of this thesis. The preparation of novel titanium tanning agent, factors affecting titanium tannage, titannium tannage mechanism and titanium combining tannage were studied.

本文从对非铬鞣体系的实用性要求出发，在对几种常用金属盐鞣剂的鞣性和鞣革综合性能的分析基础上，并结合它们的资源和毒性等方面的因素，提出了钛鞣是理想的铬鞣的替代鞣法的观点，确定了以资源丰富、无毒和鞣革综合性能好的钛盐代替铬盐的研究方向，研究了新型钛鞣剂的制备方法、影响钛鞣的因素，并对钛鞣机理和钛结合鞣法等方面进行了深入的研究。

The result showed that some of properties of the leather made by this new technique are better than the ones made by normal process. The new technique without pickling not only leave pickling and basifying out of consideration, but also reduce chrome and clears up the pollution of salt brought from pickling to the environment.
