【摘要】 将二羟基二苯砜-萘磺酸类合成单宁与铬鞣剂、锆鞣剂、钛鞣剂和硫酸铝复合，得到各种含单金属的合成鞣剂和含多种金属的合成鞣剂。分别将其复鞣猪蓝湿皮，采用正交试验法研究铝、锆和钛对多金属合成鞣剂性能的影响。试验结果表明获得一种性能优于含铬合成鞣剂的多金属合成鞣剂是可能的。更多还原

【Abstract】 DDSNSA Syntan was complexed with the chrometan, the zirconiumtan, the titaniumtan and aluminum sulfate, the monometal - syntans and polymetal syntans were obtained. Pig wet blue skins were retanned with them respectively. The results Showed that it is possible to get a syntan containing the polymetals on the behavior of which will outstrip that of the syntan only containing the chrome更多还原
