The use of acid clay

- Jan 05, 2018 -

 If you talk about a product, then it is necessary to understand the characteristics of this product, it is a goal to study it. Especially for chemical products, they have their own physical and chemical properties, and these are the important information and value of the researchers. In this article we take a look at the relevant knowledge of acid clay.


Acid white clay, also known as natural bleaching earth (Al2O3 · 4Si02 · nH2O), that is naturally produced bleaching properties of white clay itself is based on montmorillonite, albite, quartz as the main component of white, gray-white clay, Is a bentonite. It is mainly vitreous volcanic rocks after the decomposition of the product, after the water does not swell, the pH of the suspension is weakly acidic and bentonite phase difference, the bleaching performance worse than the activated clay. The color is generally yellow, green and white, gray and so on. Density 2.7-2.9g / cm, apparent density is often low due to porosity. Chemical composition and ordinary clay, the main chemical composition is aluminum oxide, silicon dioxide, water and a small amount of iron, magnesium, calcium and so on. No plasticity, high adsorption. Due to the large amount of hydrous silicic acid, the litmus is acidic; the water is easily cracked and the water content is very large. Mainly used as foundry sand accessories, glass raw materials, solvent recovery of net sink agent, mineral oil, animal oil, vegetable oil and other oil purification agent. The use of its adsorption properties, but also processed into machinery shop floors and other trees used to prevent oil seepage, non-slip and so on.
