【摘要】 通过分析采用近十种表面活性剂对鲜猪皮的脱脂效果,脱脂废液中还原糖含量和氮含量以及扫描电镜、光学显微镜对几种具代表性的表面活性剂脱脂前后生皮组织构造的观察,发现在碱性条件下非离子型和阴离子型表面活性剂除有润湿、去污、脱脂作用外对生皮的纤维间质有较强的溶出作用,对生皮表皮也有一定分离效果。在制革湿加工时使用适当的表面活性剂,有助于操作液的均匀渗透,松散胶原纤维束,提高化工材料的作用效果。

【Abstract】 Performaces of 10 kinds of surface active agents(SAA) on fresh pigskin in degreasing process were investigetecl, the quantities of reducing sugar and nitrogen in degreasing waste liquor Were determined. The changes of skin tissue structures after degreasing have been observed by SEM and LM. The results show that nonionic and anionic SAA in basic condition express strong abilityu to remove interfibrillar substance and have some action to separate epidermis tissue. Application of the optimum SAA formula in wet process is useful for loosing collagen fibril structures and for evenly permeating and mildly actting of chemical material.
