(1) Organic solvents.
(2) Alkaline solution.
When cleaning with alkaline solution, it is generally necessary to heat the solution to 80~90 degree . Rinse with hot water after degreasing to remove residual lye on the surface and prevent parts from being corroded.
(3) Chemical cleaning solution.
It is an aqueous solution prepared by a chemically synthesized water-based metal cleaning agent. The metal cleaning agent is mainly composed of surfactants and has a strong decontamination ability.
In addition, there are some auxiliary agents in the cleaning agent, which can improve or increase the comprehensive performance of the metal cleaning agent such as anti-corrosion, anti-rust, and carbon deposition.
The common cleaning agents configured with chemical cleaning fluids include LCX-52 water-based metal cleaning agent, CW metal cleaning agent, JSH high-efficiency metal cleaning agent, D-3 metal cleaning agent, DJ-04 metal cleaning agent, and NJ-841 cleaning agent , 817-C cleaning agent, CJC-8 liquid metal cleaning agent.
The preparation method, concentration, cleaning temperature and heating measures of the above-mentioned cleaning agents must strictly abide by the requirements of their instructions. When cleaning by hand, the temperature should be strictly controlled, and it can be cleaned with a brush or a cloth. If there is serious oil stain or carbon deposit, it can be scrubbed with a wire brush. It should be soaked for a certain period of time before cleaning to meet the needs of wetting and soaking. Cleaning can be divided into rough cleaning and fine cleaning. If the cleaning liquid after cleaning is not seriously oily, you can skim off the floating oil on the upper layer and use it again.
(1) Scrub.
Under normal circumstances, it is not suitable to use gasoline, because it has fat-dissolving properties, which will damage people's health and cause fire easily.
(2) Boil and wash. Put the prepared solution and the parts to be cleaned together into a cleaning pool of appropriate size welded with steel plates, heat it to 80~90 degree with a stove under the pool, and boil for 3-5 minutes.
(3) Spray washing.
(4) Vibration cleaning.
(5) Ultrasonic cleaning.
