二乙二醇—水混合液能满足高比重液压系统全天候使用。为摸拟实际液压系统中多金属接触腐蚀,采用钢—铝青铜接触腐蚀、高温回流腐蚀试验、测定腐蚀电位等方法,选定了液压防锈液的最佳配方。该缓蚀剂群对钢、铜、黄铜、铝青铜、锌、铝、镀铬件等都有良好的缓蚀作用。经23个月的实际使用。证明对上述金属的保护作用令人满意。
Diethylene glycol - water mixture to meet the high proportion of hydraulic system all-weather use. In order to simulate the contact corrosion of multimetal in the actual hydraulic system, the optimum formula of hydraulic anti-rust solution was selected by the methods of contact corrosion of steel-aluminum bronze, high-temperature reflow corrosion test and determination of corrosion potential. The corrosion inhibitor group of steel, copper, brass, aluminum bronze, zinc, aluminum, chrome-plated pieces have a good corrosion inhibition. After 23 months of actual use. Proof of the above metal protective effect is satisfactory.
