There are three ways to deal with oil pollution in Jinan ground leveling. They are organic solvent cleaning, alkali cleaning and hydrochloric acid washing. Now Jinan ground leveling manufacturer will talk about these three ways for you.
Organic solvent cleaning method:
Stopping deoiling with organic solvents is a general deoiling method with high efficiency. It is suitable for all kinds of oils and fats without affecting the physical properties of the substrates. But inorganic salts and alkaline substances can not be removed at the same time, and oil removal is not complete. Solvent volatilization is dangerous to fire and poisoning. Therefore, the use of organic solvents requires strong solubility, unsuitable for fire, high toxicity and slow volatilization. The commonly used cleaning solvents are dilute solvents, gasoline solvents, petroleum solvents, turpentine solvents, toluene solvents, diphenyl solvents and chlorine solvents.

Alkali cleaning air:
It is one of the simplest and oldest methods and is widely used because of its low cost. Mix one kilogram of caustic soda with 20 kilograms of water and stop scraping in the air to neutralize hydrochloric acid in the air.
Flushing with hydrochloric acid:
Cleaning with hydrochloric acid is mainly degreasing. The concentration of hydrochloric acid should not be too high, reaching 4-5%. For some oil products, it can be several times more serious than that at the central level. The application of this method must pay attention to safety, do a good job of ventilation, if accidentally spilled by hydrochloric acid, need to be immediately washed with a large amount of clean water.
