How to acidify vermiculite? Vermiculite is a natural, non-toxic mineral that expands when exposed to high temperatures. It is a relatively rare mineral and is a silicate. Its crystal structure is monoclinic, and it looks like mica in appearance. Because vermiculite has ion exchange capabilities, it has a great effect on soil nutrition. Acidified vermiculite has the characteristics of good adsorption, thixotropy, thermal stability, plasticity and adhesion.
The ingredients for vermiculite acidification treatment consist of expanded vermiculite, attapulgite clay, magnesium oxide, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium carbonate. Vermiculite acidification treatment method: Input the acidified vermiculite ingredients into the vermiculite vertical grinding mill for grinding. The particle fineness of the grinding powder is ≤0.074 mm. The powder after grinding is acidified vermiculite.
The production method of acidified vermiculite adopts acidification first and then compound ingredients, which can avoid the chemical reaction of sulfuric acid with instant sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium carbonate; after acidification of vermiculite, Controlling the pH value between 5.0 and 7.0 can improve the utilization of expanded vermiculite. Acidified vermiculite is suitable for the production of environmentally friendly materials, garden materials, building materials, foaming agents and fire-fighting products.
How to acidify vermiculite? Vermiculite vertical grinding mill is the main equipment used for acidification treatment of vermiculite. As a manufacturer of vermiculite mills, Guilin Hongcheng's vertical mills can process 80-2500 mesh vermiculite powder and have good adaptability to expanded vermiculite, attapulgite clay, magnesium oxide and other materials and mixtures. It can be adapted to the grinding production of vermiculite acidified materials. If you have relevant needs, please leave us a message for details.
