本文论及修订栲胶标准意义,阐述了栲胶质量、栲胶标准方面的问题。根据国内生产现状和使用要求,在充分考虑和研究有关栲胶标准的政策性、技术性和经济性前提下,提出修订栲胶标准的建议。 附录有修订后正式颁行的同家标准——栲胶标准(GB2616-2623-81)的各项技术质量指标。

For diminishing chrome pollution and increasing utilization of vegetable tannins in light leather manufacturing, the properties of six commercial vegetable tannin extracts (i. e. extracts from Quercus acu-tissima I , Larix gmelini Ⅱ, Albizzia kalkora Ⅲ, Casuarina equisetifolia Ⅳ, Myrica rubra V, Phyllanthus sp.

For diminishing chrome pollution and increasing utilization of vegetable tannins in light leather manufacturing, the properties of six commercial vegetable tannin extracts (i. e. extracts from Quercus acu-tissima I , Larix gmelini Ⅱ, Albizzia kalkora Ⅲ, Casuarina equisetifolia Ⅳ, Myrica rubra V, Phyllanthus sp. Ⅵ) in Vegetable-Aluminum combination tannage were studied. Goat skins were pretanned with each tannin extract and then retanned with A12(SO4)3. The results obtained show that experiment with extract I gives the highest shrinkage temperature and the lowest tensil strength, and the result with extract I is just on the contrary. The best one is extract Ⅳ, which gives considerable high shrinkage temperature and better tensil strength, extract is also quite good. Both extracts Ⅳ and Ⅵ could be used in Vegetable-Aluminum combination tannage and extracts I , Ⅱ can also be used when mixed in a proper ratio. Pretreatment of the pelt with 1% HCHO before vegetable pretan causes great increase in shrinkage temperature of the leather and the tensil strength of leather formed could be improved by fatliquoring.

研究的目的,为了进一步发展国产栲胶在制革工业上的应用,以代替部分或全部铬鞣剂而减少制革工业中铬盐对环境的污染。本文研究了橡椀(水解类),山槐、木麻黄、落叶松(缩合类),杨梅、抽柑(混合类)等常用的6种国产栲胶,在植—铝结合鞣法中所表现的性质。结果表明:①橡椀的结合鞣革,收缩温度最高,但抗张强度最低。落叶松的结合鞣革,收缩温度最低,但抗张强度最高。收缩温度和抗张强度都比较好的为木麻黄,其次为柚柑。杨梅和山槐的结合鞣革,虽然收缩温度较高,但强度低,故实施植—铝结合鞣法,可以选用水麻黄或柚柑,也可采取将落叶松及橡椀,按一定比例混合使用的办法;②植鞣前进行甲醛预处理,可提高结合鞣革的收缩温度;③加脂可提高成革的抗张强度。

A new type of axle sealing pump used in tannin extracts industry was described in detail.

本文从我国栲胶生产的实际出发,较详细地叙述了栲胶泵轴密封的研究情况,并研制了一种新颖的停车密封——飞球离心式机械停车密封装置。该装置结构简单,计算容易,控制灵活,密封可靠,寿命长,维修简便,已成功地解决了栲胶泵的轴封问题。该装置也适用于别的工业部门用来输送其他介质,具有优良的密封性能,其用途广泛。
