摘要： A composition of antiseptic metal working fluids is provided to prevent decomposition of the working fluid by excluding non-biodegradable formaldehyde and using environment-friendly materials. A composition of antiseptic metal working fluids consists of minerals of 50~70wt.% having kinematic viscosity of 8~31cst at 40°C, polyoxyethylene alkyl ester(3~6 mol.) of 5~10wt.%, polyethylene glycol mono-oleate of 5~10wt.% having molecular weight of 400~600, chloroparaffin of 10~20wt.% having the content weight of 42%, sulfol 465 of 5~10wt.%, potassium hydroxide below 2wt.%, ion exchanged water of 2~7wt.%, sodium gluconate of 1~5wt.%, and an additive of 0.1~0.5wt.% such as a silicone antifoaming agent. The mineral reduces friction resistance and facilitates machining work by increasing lubricating ability between a workpiece and a tool in cutting and winding ferrous and nonferrous metals.

摘要： An engine oil composition for a compressed natural gas engine is provided to protect an engine due to a good wear preventing function and a valve train and a piston due to a good oxidation preventing function and to extend the exchange period of engine oil. An engine oil composition for a compressed natural gas engine consists of base oil of 78~90wt.%, an anti-oxidation agent of 0.05~3wt.%, a purifying agent of 1~7wt.%, a viscosity index improving agent of 0.1~5.0wt.%, an anti-foaming agent of 0.0005~2wt.%, and a wear resistant agent of 0.5~5wt.%. The wear resistant agent is produced by mixing primary zinc-dialkyl dithiophosphate and secondary zinc-dialkyl dithiophosphate at the weight rate of 2:1. The base oil has a coefficient of kinematic viscosity of 3~10cSt at 100deg.C. Mineral oil and synthetic oil of a fixing agent with a viscosity index over 100 are individually used or mixed.
