In chapter three, various theories and experience on the dispersion of nano-powders proposed by former researchers were generalized and reviewed. Technical standards and experimental process for determining technological parameters were suggested for the dispersion of nano-scaled metal oxides in aqueous medium according to their surface wettability, surface charge, the dependence of surface charge on pH and the compatibility of surfactants with pH and pH adjusting agents. Based on these suggested standards and experimental method, highly stable and dispersive aqueous suspensoid of nm-ZnO, nm-TiO〓, nm-Co〓O〓 and nm-MnO powders were prepared successfully and surface modification on these nano-powders was also achieved.

The results of research on the factors affecting titanium tannage show that high concentration NaCl medium has larger negative effect on titanium tannage. When the NaCl concentration exceeds 5%, the titanium tanning action is reduced rapiddly. Traditional NaCl pickling is unsuitable for titanium tannage, tanning in water medium directly, the best tanning effect can be obtained, so titanium tanning can not only eliminate chrome pollution, but also diminish salt pollution. The optimum tanning conditions for HPZ-Ti tan liquor are pH3. 5, TiO〓 offer of 7. 5%(based on the weight of 65% moisture pelt), the best Bascity of tan liquor is between 30% and 50%.

以HPZ—Ti鞣液为基础，研究了不同鞣制介质，鞣制pH值，鞣剂用量和浓度，鞣液的碱度，不同提碱剂，不同的预处理和后处理等因素对钛鞣的影响，结果表明：高浓度的NaCl溶液介质对钛鞣有很大的负面作用，当介质NaCl浓度超过5%，革内钛的结合量和革的Ts明显降低，传统的高浓度NaCl浸酸工艺不适合于钛鞣，在水介质中直接鞣制效果最好，所以钛鞣不仅消除了铬污染而且大大降低了盐的污染。
