What is acidizing treatment with a vermiculite grinding mill?

Vermiculite is a natural, non-toxic mineral, which will expand under high temperature. It is a rare mineral, belonging to silicate. Its crystal structure is monoclinic system, which looks like mica in appearance. Because vermiculite has the ability of ion exchange, it has a great role in soil nutrition. The acidified vermiculite has the characteristics of good adsorption, thixotropy, thermal stability, plasticity and cohesiveness. Therefore, how is vermiculite acidified? The manufacturer of vermiculite grinding mill, will introduce the vermiculite acidification treatment method below:

The ingredients for vermiculite acidification treatment are composed of expanded vermiculite, attapulgite clay, magnesium oxide, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate. Vermiculite acidification treatment method: put the acidified vermiculite ingredients into the vermiculite grinding mill for grinding, and the particle fineness of the powder is ≤ 0.074mm. The powder after grinding is vermiculite after acidification. The production method of acidified vermiculite adopts acidification first and then composite batching, which can avoid chemical reaction between sulfuric acid and instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate; After the vermiculite is acidified, the pH value is controlled at 5.0~7.0, which can improve the utilization rate of expanded vermiculite. The acidified vermiculite is suitable for the production of environmental protection materials, garden materials, building materials, foaming agents and fire protection products.

Vermiculite grinding mill is the main equipment used for vermiculite acidification treatment. GUIKUANG is the manufacturer of vermiculite grinding mill. The vermiculite grinding mill produced has been widely used in the market. Our vermiculite grinding equipment includes vermiculite Raymond mill, vermiculite vertical roller mill, vermiculite ultra-fine mill and other types. They can process 80-2500 mesh vermiculite powder, and have good adaptability to expanded vermiculite, attapulgite clay, magnesium oxide and other materials and mixtures, and can adapt to the grinding production of vermiculite acidified materials.
