News Detail
The oil stains of rubber paver machine parts are mainly formed by non-saponifiable oil,dust, impurities, etc. Non-saponifiable oils cannot work with strong alkalis, such as various mineral oils and lubricating oils, which are not soluble in water, but soluble in organic solvents. There are two methods to remove this kind of oil, chemical and electrochemical; common cleaning liquids are organic solvents, alkaline solutions and chemical cleaning liquids, etc.; cleaning methods include manual cleaning and mechanical cleaning. There are three main methods for cleaning liquids:
1. Alkaline solution. Alkaline solution is an aqueous solution of alkali or alkaline salt. It uses the emulsification effect of emulsifiers on non-saponifiable oil to remove oil. It is one of the most widely used decontamination cleaning solutions. When cleaning with alkaline solution. After degreasing, rinse with hot water to remove residual lye on the surface to prevent corrosion of rubber paver machine parts. It is also very practical for rubber paver machine.
2. Organic solvents. Common ones are kerosene, light diesel, gasoline, acetone, alcohol and trichloroethylene. Using this dissolving method to remove oil, it can dissolve all kinds of grease. The advantages are that it does not need to be heated, is easy to use, does not damage the metal, and has a good cleaning effect.
3. Chemical cleaning fluid. It is a chemically synthesized aqueous solution of water-based metal cleaning agent with strong decontamination ability.
