用五种封存材料作了对比性试验(包括:石油型防锈剂——743号防锈脂和工业凡土林,稀释性防锈油、挥发性缓蚀剂,甘油—亚硝酸纳缓蚀剂等),试验结果表明:甘油—亚硝酸钠缓蚀剂优于其它四种防锈材料,可以在生产中使用,首先可用于冲压保持架的成品防锈。根据在保持架车间试用和多次抽检的桔果,从未发现锈蚀痕迹,产品锈蚀率由过去的60—80％(工业凡土林热涂防锈)下降为零。 本文介绍了试样处理与试验结果。
Five types of sealers were used for comparative tests (including: oil type rust inhibitor - No. 743 anti-rust grease and industrial soil, dilute anti-rust oil, volatile corrosion inhibitor, glycerol - nitrite corrosion inhibition Etc.), the test results show that: glycerin - sodium nitrite corrosion inhibitor is better than the other four anti-rust materials, can be used in the production, first of all can be used for the finished product stamping cage rust. According to the trial in the cage workshop and multiple sampling of the orange fruit, never found traces of corrosion, corrosion rate of products from the past 60-80% (industrial soil thermal anti-rust coating) dropped to zero. This article describes the sample handling and test results.
