以热氧化聚乙烯为基础的含蜡高分子固体润滑膜经我厂多年来大生产的检验,认为该膜具有附着力强、摩擦系数低、磨损小、耐腐蚀性好等优点,是当前较好的一种润滑膜。但成膜液中热氧化聚乙烯的含量是影响膜层质量的重要因素之一,必须加以控制。 由于聚乙烯通过热氧化降解后,在同一批产品中存在着不同链节的热氧化聚乙烯,给色谱等仪器分析造成困难,虽经分离后可用重量法测得热氧化聚乙烯的含量,但该法的操作步
Thermal oxidized polyethylene-based waxy polymer solid lubricant film has been tested by our factory over the years and found that the film has the advantages of strong adhesion, low friction coefficient, low wear and corrosion resistance, A good kind of lubricating film. However, the content of thermal oxidized polyethylene in the film forming fluid is one of the important factors that affect the quality of the film and must be controlled. Due to degradation of polyethylene by thermal oxidation, the same batch of products exist in different sections of the thermal oxidation of polyethylene, chromatography and other equipment caused by the difficulties, though after separation can be measured by gravimetric method of thermal oxidation of polyethylene, but The method of operation
