摘要
毛皮发泡技术是基于皮板胶原纤维在酸性溶液中产生充水膨胀作用 ,促使其纤维充分分离、松散 ,从而明显地提高鞣制质量的技术。本文从四个方面进行研究 :(1)发泡剂的筛选 ,在同样条件下比较硫酸、甲酸、醋酸、乳酸和酒石酸及它们的混合物对皮板的发泡效果 ;(2 )对工艺条件 ,即PH值 (2 .0 -4 .0 )、温度 (10 - 4 0℃ )、时间 (2 - 4 8h)进行筛选 ,得到安全生产范围和最佳范围 ;(3)通过在发泡过程中分别加入不同的中性盐和助剂进行比较 ,明确各物质对发泡系统的影响 ;(4)在前面研究的基础上 。
This paper is concerned with the technology of acid bating in fur making in these four files:(1)The selection of acid.A best acid for acid bating is to be selected form formic acid?acetic acid?lactic acid and so on.(2)The safe purview and the best purview of control bargain in the acid bating,such as the pH?temperature and time.(3)The influence to the acid bating if salt or other things are joined in.(4)The correlation technology to the acid bating technology.
