总结了几年来的防銹工作经验。改进了工序间防銹,将平面、无心工序冷却液中的乳化油膏含量增加到2.5—3％,其它工序含量为1.5％。机台防銹采用含有2—3％的亚硝酸钠水溶液,中间仓库的防銹仍然采用亚硝酸钠热防銹的办法,加强了及时防銹。进入装配的产品根据要求不同采用1％的204—1汽油溶液及5％的204-1汽油溶液及901油进行防銹,军工产品仪表轴承采用时时序序浸泡的防銹办法。中间库入库前增加肥皂水,碱溶液及三乙醇胺水溶液清洗工序,中大型产品装前采用OH-10乳化剂清洗后用三乙醇胺水溶液及汽油清洗,再用置换性防銹油防銹后进入装配。成品油封包装改用冷涂油,中大型产品采用204-1及B型204—1防銹油防銹。包装材料采用聚乙烯及聚氯乙烯两种材料。仪表轴承采用101防锈油及三乙醇胺水溶液两种方法,用塑料管封存。还介绍了发动群众做好防銹工作的经验。
Summarizes the rust preventive work experience over the past few years. Improved rust prevention between processes, increased the emulsified grease content in the coolant for flat and uncentred processes to 2.5-3%, and the other process content was 1.5%. The rust-proofing machine used contained 2-3% of sodium nitrite solution, and the rust prevention in the intermediate warehouse still used the method of sodium nitrite heat rust prevention to strengthen the timely rust prevention. Into the assembly of the product according to the requirements of different 1% of the gasoline solution of 2-1, and 205 of the 204-1 gasoline solution and 901 oil for rust, military products, instrument bearings used when the time sequence of immersion rust. The intermediate library is filled with soapy water, alkali solution and triethanolamine aqueous solution before washing. The medium and large products are cleaned with OH-10 emulsifier before installation, cleaned with triethanolamine solution and gasoline, and then replaced with a rust preventive oil. assembly. The oil seal of the finished product was changed to cold oil, and the medium and large products were made of 204-1 and B type 204-1 antirust oil. Packaging materials are made of polyethylene and polyvinyl chloride. The instrument bearing uses 101 anti-rust oil and triethanolamine solution in two ways, sealed with plastic pipe. It also introduced the experience of mobilizing the masses to do rust-proof work.
