【摘要】 本论文研究了一种新的兔毛皮铬鞣工艺—采用有机溶剂代替水作为铬鞣介质,探索了浸酸兔皮皮板中水分含量,铬粉用量及溶剂介质中水的比例对鞣制效果的影响,并与常规铬鞣工艺进行了分析。结果表明:在兔皮皮板水分含量约为40%,有机溶剂比例为三氯乙烯:异丙醇:水=95:1:4或90:1:9,铬粉用量为5g/L的条件下,获得了良好的鞣制效果,皮板收缩温度可达95℃。更多还原

【Abstract】 This paper studied the novel tanning process that chrome tanning in the medium of organic solvent trichloroethylene,and explored the effect of the moisture content in the picked rabbit skin,the dosage of chrome and the solvents ratio on the tanning results.And the chrome-tanned pelt within organic solvent were compared with the pelt tanned within water medium.The result showed that the moisture content of about 40%,the ratio of trichloroethylene,isopropyl alcohol and water 95:1:0 or 90:1:9 and the chromium powder 5g/L gave the optimum tanning effect.更多还原
