Perlite after the acidification

The present invention discloses a perlite of an acidified, elements of the technical proposal is acidified after the perlite formulations expanded perlite, attapulgite clay, magnesium sulfate, sodium silicate instant, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate composition; perlite formulations after acidification the input mill grinding, milling the powder is acidified perlite. Perlite production process after acidification was acidified and then take the first composite ingredients, can be avoided with instant sulfate sodium, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate chemical reaction; expanded perlite elapsed after acidification , pH value was controlled at 5.0 to 6.5, you can improve the utilization of perlite. Acidified perlite having good adsorption properties, thixotropy, thermal stability, moldability and adhesion characteristics. Perlite after the acidification is suitable for production of environmentally friendly materials, building materials, blowing agents and fire protection products.
