本文分析了减压轴氮化前用汽油清洗产生花斑的原因,通过去污机理的研究,比较了几种表面活性剂的渗透、分散能力,选择辛烷基苯酚聚氧乙烯醚-10为清洗剂的必要成分。由于硅酸钠有防止污垢再沉积,软化水、悬浮污垢等优良特性。因此,选择硅酸钠为助洗剂研制成的D-1清洗剂,经热处理分厂两年多使用,清洗后零件表面光洁,达到了白亮层深度和扩散层深度的技术指标,解决了长期产生花斑的质量问题,节约了的汽油,取得了较大的经济效益。
In this paper, the reasons for the speckle generation of gas before the nitriding of the decompression shaft were analyzed. The mechanism of decontamination was studied. The penetration and dispersion ability of several surfactants were compared. The octylphenol polyoxyethylene ether-10 Cleaner essential ingredients. As sodium silicate to prevent the redeposition of dirt, softened water, suspended dirt and other fine features. Therefore, the choice of sodium silicate as a builder developed D-1 cleaning agent, the heat treatment plant more than two years to use, after cleaning the surface smooth parts, reaching the depth of white and diffusion layer depth of technical indicators to solve the long-term Produce the quality problem of the piebald, economize on the gasoline, have obtained greater economic benefits.
