摘　　要：将用常规工艺浸水、酶脱毛的小牛皮,分别用不同用量的氢氧化钙、氢氧化钠、NA-N膨胀剂进行碱膨胀,测定碱膨胀不同时间碱皮和蓝皮Ts、膨胀液中羟脯氨酸的含量、脱碱后裸皮进行组织切片后的显微镜观察图、成革的物理力学性能。结果表明:NA-N膨胀剂处理后的效果比用氢氧化钙处理后的效果还要好,因此NA-N膨胀剂一种可以代替氢氧化钙作为小牛皮革的清洁生产材料。The calf skin,treated with traditional soaking,dehairing with enzyme was swelled with different amount of calcium hydroxide,sodium hydroxide and NA-N swelling agent.According to the time of swelling,Ts of liming hide and wet blue,hydroxyproline content in swelling liquids,some physical mechanics of leather samples after chrome tanned were determined.And pelt histological microstructure was observed after dealkalization.It shows that the effect of NA-N swelling agent was better than calcium hydroxide in this...
