摘　　要：采用盐法脱水并结合使用低碱度 KMC蒙囿铬鞣剂在高 p H值条件下对皮粉及猪皮进行鞣制。考察了铬鞣剂的渗透及革的收缩温度。结果表明 ,此法能使铬在革内的分布与常规铬鞣法相当 ,并使铬的吸收率达到 90 %。在鞣制中 ,盐和 KMC的合适用量分别是 6 %～ 9%和 7% ,革的收缩温度是The experiments on hide powder and pigskins tanned with high pH chrome tanning method were made and the permeation of chrome and the shrinkage temperature of leather were studied. When pelts are pretreated with salt and tanned with KMC masking chrome tanning agent at lower basicity, the Cr 2O 3 percentage distribution in leather tanned with high pHchrome tanning method, equated with that treated with ordinary chrome tanning method, and the rate of chrome absorption reaches 90%.
