Because of its nonpoisonous, DMC can substitute phosgene , dimethyl sulfate or methylating used as methyl pharmaceutical to improve the security of production and reduce the environmental pollution; As the solvent, DMC can substitute fluorine lyons , methyl chloroform , trichloroethylene , benzene , dimethylbenzene, etc.. And it can be used as the paint dope, clean solvent. As gasoline additive, DMC can raise hard octane value and oxygen content and improve its antiknock possibility.

由于DMC无毒，可替代剧毒的光气、硫酸二甲酯等作为甲基化剂或羰基化剂使用，提高生产操作的安全性，降低环境污染；作为溶剂，DMC可替代氟里昂、三氯乙烷、三氯乙烯、苯、二甲苯等用于油漆涂料、清洁溶剂等；作为汽油添加剂，DMC可提高其辛烷值和含氧量，进而提高其抗爆性。

After looking up a large amount of native and foreign information, the materials used in the experiment were as follows: PTFE base, graphite filler, molybdenum disulfide filler, copper powder filler, carbon fiber and so on. The experimental method is that the formula was designed according to uniform experimental method, the relationship between formula and frictional property was found with spline function and then the representative test points were chosen from fitting curve to make verification test for optimization.

经过查阅大量国内外文献资料后确定原料为：聚四氟乙烯树脂为基体，加入石墨、二硫化钼、铜粉、碳纤维等填料；试验方法为：根据均匀试验方法设计配方，用样条函数找出配方与摩擦性能的关系，然后在拟合曲线上选取具有代表性的试验点进行验证试验，达到优化的目的；制备工艺：冷压烧结法制备固体润滑剂。
