Diatomite       

Diatomaceous earth is deposited from the remains of single-celled aquatic algae. A diatomaceous earth deposit formed under certain geological conditions. Diatomaceous earth has the characteristics of porosity, large specific surface area, low density, good adsorption, acid resistance, and heat resistance, and its main component is amorphous SiO2. After the original diatomaceous earth ore is excavated from the mine, it is generally divided into three categories through processes such as casting, drying, and production: natural diatomaceous earth, calcined diatomaceous earth, and fused calcined diatomaceous earth.

Natural diatomaceous earth:

Natural diatomaceous earth, due to its preservation of its original structure, clear pore structure, high porosity, large specific surface area, and strong adsorption ability, is widely used as an adsorbent and filter aid in the food industry, petroleum industry, and chemical industry.

Calcined diatomaceous earth:

Calcined diatomaceous earth is a material that is carefully selected and then roasted at a high temperature of 700-900 ° C. It is then crushed and sieved, and roasted in an orange yellow, pink to reddish brown color. Mainly used as functional filler.

Assisted melting and calcination of diatomaceous earth：

Assisted melting and calcination of diatomaceous earth involves adding selected raw materials to an appropriate amount of solvent, roasting at high temperatures ranging from 900 to 1200 ° C, followed by crushing and screening, resulting in a powder white roasted product.

Product advantages:

     Diatomaceous earth has a series of excellent characteristics, such as light weight, soft texture, porosity, sound insulation, heat resistance, acid resistance, neutral pH value, non-toxic, good suspension performance, strong adsorption performance, obvious pore structure, high porosity, strong adsorption ability, large specific surface area, and stable chemical properties. It is a widely used functional filler in many industrial fields.

Application field:

    Diatomaceous earth is widely used in industries such as pesticides, fertilizers, coatings, plastics, rubber, papermaking, toothpaste, abrasives, cosmetics, ceramics, and centrifugal casting pipe release agents.

Rubber field:

Fillers in various rubber products, such as vehicle tires, rubber pipes, V-belts, rubber rolling, conveyor belts, car mats, etc., can significantly enhance the rigidity and strength of products, and can improve the performance of products with heat resistance, wear resistance, heat preservation, anti-aging and other chemical actions.

Plastic field:

      Household plastic products, building plastic products, agricultural plastic, window and door plastic, various plastic pipes, and other light and heavy industrial plastic products.

Paper industry:

Various types of paper such as office paper and industrial paper; The body is light and soft, and the addition of diatomaceous earth can make the paper smooth, lightweight, and strong, reducing the expansion and contraction caused by humidity changes.

Paint and coating field:

Furniture, office paint, architectural paint, machinery, home appliance paint, oil printing ink, asphalt, automotive paint, and other paint fillers.

Polishing and friction field:

Polishing of brake pads, mechanical steel plates, wood furniture, glass, etc. in vehicles; Strong lubrication performance.

Building insulation field:

Roof insulation layer, insulation bricks, calcium silicate insulation material, porous coal cake furnace, sound insulation and fireproof decorative board, wall sound insulation and decorative board, floor tiles, ceramic products, etc.

Other fields:

High quality fillers with strong sun protection, soft and light physique, and ability to eliminate leather pollution for balloon products: light capacity, neutral pH value, non-toxic, light and smooth powder, good strength performance, sun protection and high temperature resistance. Diatomaceous earth is applied in industries such as coatings, paints, and sewage treatment.
