由北京内燃机总厂、北京东城区粘合剂厂与我所组成的三结合小组,对“合成淬火剂”进行了试验研究,在生产鉴定的基础上,曾于1973年制成了如下表成份的定型产品。其后,根据使用中不断提出的新要求,为进一步完善“合成淬火介质”的性能,进一步提高其防诱和防腐能力,对其原有成份调整补充如下: 聚乙烯醇(聚合度1750,醇解度88%) 10% 防锈剂三乙醇胺 1%
By the Beijing Internal Combustion Engine Plant, Beijing Dongcheng District Adhesive Factory and I composed of three combined groups, “synthetic quencher ” conducted a pilot study, based on the identification of production, was made in 1973 as follows Table ingredients stereotypes products. Subsequently, according to the new requirements put forward constantly in use, in order to further improve the performance of “synthetic quenching medium” and further enhance its anti-seizing and anticorrosive capability, the original composition adjustment is supplemented as follows: polyvinyl alcohol (degree of polymerization 1750 , Alcoholysis 88%) 10% rust inhibitor triethanolamine 1%
