What is activated bleaching earth

Sunrise (Hong Kong) Group Limited | Updated: Apr 24, 2017

Activated Bleaching Earth refers to any fine, natural, high adsorption rate of soil-like material, with fat, grease or oil from the adsorption of impurities or the ability of the material. It is also called activated clay, active clay, adsorption clay, decolorization soil, adsorbent, bleaching clay and so on.


Characteristics of bleaching earth

Activated Bleaching Earth was made of high-quality natural non-metallic mineral - calcium bentonite as the main raw material, supplemented by scientific formula, refined by a special processing technology, apparent gray or light pink powder, is the ideal alternative to activated carbon.

Bleaching Earth has a wide range of bleaching performance, bleaching force is great, have a strong adsorption and purification on the pigment, impurities.

Activated Bleaching Earth in the application has a strong stability, and the application is very convenient and safe, without changing the production of the original production process.

Activated Bleaching Earth filter cake can be recycled, do not cause pollution to the environment.

The decolorization rate is high, with low oil rate, filtration speed, low free acid content.


The performance of bleaching earth

1, strong adsorption capacity, high decolorization rate, low oil consumption rate, fast filtration rate, less added amount;

2, can effectively remove the total phospholipids, soap and trace metal ions, can be used as a natural antioxidant;

3, can remove oil in the aflatoxin, pesticide residues and other toxins and odor substances;

4, after decolorization of the oil acid value does not rise, do not return color, clear and transparent, stable quality, long shelf life.

5, especially for mineral oil, vegetable oil, animal oil refining production.


The scope of application of bleaching earth


Can make vegetable oil, mineral oil, animal oil, enzymes, monosodium glutamate, polyether, sugar, wine and other adsorption decolorization. In the chemical industry, environmental protection and other industries as filter, catalyst, adsorbent, desiccant, deodorant odor, water purification agent, sewage treatment agent, bleaching agent.
