White oil is a colorless, translucent oily liquid with no or almost no fluorescence. , odorless and tasteless when cold, with a slight petroleum-like odor when heated. Insoluble in water and ethanol, soluble in volatile oils, miscible in most non-volatile oils, stable to light, heat, acid, etc., but long-term exposure to light and Heat will slowly oxidize.
Commonly used are industrial grade white oil, cosmetic grade white oil, medical grade white oil, food grade white oil, etc. Different types of white oil also have different uses. Among them, industrial grade white oil is made from base oil produced by hydrocracking as raw material. It is obtained after deep dewaxing, chemical refining and other processes. It can be used in chemistry, textile, chemical fiber, petrochemical industry, electric power, agriculture, etc., and can be used in PE , PS, PU and other production.
According to Bitehua, which supplies white oil, industrial grade white oil can play a lubrication and anti-rust role in powder metallurgy products:
White oil can be used as Industrial lubricants are substances that can lubricate, cool and seal the friction parts of machinery. As food machinery lubricants, they do not corrode machinery.
Industrial grade white oil (No. 5 white oil) has a certain anti-rust effect. When the air humidity is high, it may rust in a day or two. No. 5 white oil is a low-viscosity mineral oil and is mainly used as a raw material for low-viscosity lubricants, such as spindle oil, spindle oil, etc.
Powder metallurgy products are generally made into porous, semi-dense or fully dense types. Due to the characteristics of the material, electrochemical corrosion, that is, rust, is very easy to occur in an environment with high humidity. Therefore, the prevention of powder metallurgy products Rust requirements are higher, and the anti-rust oil used for porous and semi-dense products requires good permeability, lubricity and sagging properties. For example, oil-containing bearings can directly use this type of anti-rust oil to ensure their lubricity. Gears, cams, guide rods, cutting tools, etc. made of powder metallurgy can all use this type of anti-rust protection.
