两步法铬鞣的鞣革性能研究
Application of Anion and Cation Chrome Tanning Agent in the Pickling Without Salt Process
摘要
Abstract
The bated skins were pre-treated by chrome tanning without pickling and pickled by acid liquor,then,tanned by normol AB chrome tanning agents.The changes of thermal decomposition properties,fiber dispersion state,distribution of chromium in the skin were explored by DSC-TG and SEM-EDS during the together tanning of anion and cation tanning agent.The results shows that tanning agent without pickling has penetrated to the cross section of leather sample face about 200 um for 10 min,and tanning agent without pickling can penetrated into the skin piece section center when the time of pre-tanned continued to 4h,but leather sample is thin.when treated by cationic tanning agent for 30min,the chromium element distribution density of skin section significantly increased and uniform,the thickness and Ts of the blue leather significantly improved,the thermal decomposition temperature and leather fiber woven get tighten.This process removes salts in pickling,which greatly decreased the salt pollution.关键词
