为增加凡尔体的耐磨性,延长使用寿命,辽河石油勘探局机修厂修复车间“三结合”革新小组,发扬自力更生、艰苦奋斗的革命精神,试制尼龙凡尔体代替钢件凡尔体。于一九七三年七月一日试制成功。尼龙凡尔体原料:乙内酰胺、助催化剂为MDI(二苯基甲烷二异氰酸酯)尼龙凡尔体的配方:(1)一公斤乙内酰胺加烧碱1.4克;(2)一公斤乙内酰胺加入MDI4.43克,制作尼龙凡尔体每个需用乙内酰胺为1950克。尼龙凡尔体效果:尼龙凡尔体比钢材凡尔体既轻便又耐用,减轻工人劳动强
In order to increase the abrasion resistance of Versailles body and prolong the service life, Liaohe Petroleum Exploration Bureau Machinery Repair Factory repaired the workshop “three combination” innovation team, carried forward the revolutionary spirit of self-reliance and hard work, and tried the manufacture of nylon Verstel instead of steel. Trial production was successfully conducted on July 1, 1973. Nylon Versailles raw materials: lactone, cocatalyst MDI (diphenylmethane diisocyanate), the composition of the nylon Versailles: (1) one kilogram of lactam plus caustic soda 1.4 grams; (2) one kilogram of lactam Add MDI4.43 grams, making nylon pellets each need to use 1950 grams of lactam. Nylon Versailles effect: Versailles than the steel Versailles is both light and durable, reduce labor and labor
