Cleaning steps and solvent selection of small roller are mainly used in construction industry of construction machinery parts such as roller etc. mainly formed by non-saponification oil dust impurities etc. Non-saponification oil cannot play with strong alkali, such as mineral oil, lubricating oil, can not dissolve in water, but soluble organic solvent.

Organic solvents. Common features include kerosene light diesel gasoline acetone alcohol and trichloroethylene etc. Using this dissolution method degreasing can dissolve various fats. Advantages are not heating, simple use, metal no damage, cleaning effect is good. Disadvantages are mostly flammable high cost suitable parts suitable for precision parts and unsuitable hot alkali solution cleaning parts such as plastic nylon leather felt parts etc. However, it should be noted that rubber parts cannot be cleaned with organic solvents.

Alkaline solution. Alkaline solution is aqueous solution of alkali or alkaline salt. It uses emulsifier to remove oil from saponification oil. It is widely used in cleaning fluid.

Emulsification is a liquid formed tiny particles after evenly distributed in another liquid. Adding emulsifier into alkali solution forms emulsion can reduce surface tension and adhesion of oil film so oil film break into tiny oil drops no longer return to metal surface so as to remove oil pollution. Commonly used emulsifiers include soap sodium silicate (sodium silicate) bone glue gum Triethanolamine synthetic detergent etc. . Alkaline solution has different corrosion effects on metals especially aluminum corrosion resistance.

. Rinse with hot water after degreasing remove residual lye on surface prevent parts from being corroded.
