Silica gel bleaching sand refers to the production of coarse silica gel processing as raw material, is also a commonly used in the market. 1. Silica gel decolorizing sand uses the principle that silica gel itself contains a large number of nanoscale molecular structures to absorb pigments and impurities in waste oil or waste diesel.

2, low cost, wide application. Less slag is produced, so the cost is reduced accordingly. Silica gel decolorizing sand can not only wash small oil refining with crude oil, but also deal with lubricating oil, reduce first line, reduce second line oil, waste oil and other refined diesel and oil that can not be washed out with the old way, and the application is quite wide.

3, to solve the problem of waste treatment, the waste residue washed out with silica gel decolorizing sand is not bonded, not caked, not solidified, and can be reused as waste. If it is sold, it is also more expensive than the waste washed out by the old way, which solves the problem of environmental protection.
