CAS No.: 61790-53-2 Diatomaceous earth is a type of siliceous rock, composed of amorphous SiO2 and containing small amounts of Fe2O3, CaO, MgO, Al2O3, and organic impurities. Diatomaceous earth is usually light yellow or light gray, soft, porous, and lightweight. It is commonly used in industry as insulation materials, filtering materials, fillers, grinding materials, water glass raw materials, decolorizing agents, diatomaceous earth filter aids, catalyst carriers, etc.

Diatomaceous earth is generally formed from the silicate remains after the death of single-celled algae, commonly known as diatoms, and its essence is aqueous amorphous SiO2. Diatoms can survive in both freshwater and saltwater, with many types. They can generally be divided into “central order” diatoms and “feathered order” diatoms, and each order has many “genera” that are quite complex.

The main component of natural diatomaceous earth is SiO2, with high-quality ones having a white color and a SiO2 content often exceeding 70%. The single diatom is colorless and transparent. The color of diatomite depends on clay minerals and organic matter. The composition of diatomite from different mineral sources is different.

Diatomaceous earth, also known as diatom, is a fossilized diatom deposit formed after the death of a single celled plant and a deposition period of about 10000 to 20000 years. Diatoms were one of the earliest native organisms to appear on Earth, living in seawater or lake water.

This diatomite is formed by the remains of single celled aquatic plant diatoms. The unique feature of this diatom is that it can absorb free silicon in water to form its bones. When its life is over, it will deposit and form diatomite deposits under certain geological conditions. It has some unique properties, such as porosity, low concentration, large specific surface area, relative non compressibility and chemical stability. It can be applied to various industrial requirements such as coating and paint additives after changing the particle size distribution and surface properties of the original soil through crushing, sorting, calcining, air classification, impurity removal and other processing procedures.

The application scope of industrial fillers for algal soil in agriculture and pharmaceuticals: wettable powder, dry land herbicide, paddy field herbicide, and various biopesticides.

Advantages of using diatomaceous earth: pH neutral, non-toxic, good suspension performance, strong adsorption performance, light bulk density, oil absorption rate of 115%, fineness ranging from 325 mesh to 500 mesh, good mixing uniformity, no blockage of agricultural machinery pipelines during use, can play a moisturizing role in the soil, loosen the soil quality, extend the effective fertilizer time, and promote crop growth. Compound fertilizer industry: Compound fertilizer for various crops such as fruits, vegetables, flowers and plants. Advantages of using diatomaceous earth: strong adsorption performance, light bulk density, uniform fineness, neutral and non-toxic pH value, and good mixing uniformity. Diatomaceous earth can become an efficient fertilizer, promoting crop growth and improving soil quality. Rubber industry: fillers used in various rubber products such as vehicle tires, rubber pipes, V-belts, rubber rolling, conveyor belts, and car foot mats. The advantages of diatomite application: it can significantly enhance the rigidity and strength of the product, with the sedimentation volume up to 95%, and can improve the performance of the product in terms of heat resistance, wear resistance, heat preservation, aging resistance and other chemical actions. Building insulation industry: roof insulation layer, insulation brick, calcium silicate insulation material, porous coal cake furnace, sound insulation and fireproof decorative board, wall sound insulation and decorative board, floor tile, ceramic products, etc;

Advantages of using diatomaceous earth: diatomaceous earth should be used as an additive in cement. Adding 5% diatomaceous earth to cement production can improve the strength of ZMP, and SiO2 in cement can become active, which can serve as a rescue cement. Plastic industry: Household plastic products, building plastic products, agricultural plastic, window and door plastic, various plastic pipes, and other light and heavy industrial plastic products.

Advantages of using diatomaceous earth: 3. It has excellent extensibility, high impact strength, tensile strength, tear strength, light and soft texture, good internal wear resistance, and good compressive strength. Paper industry: various types of paper such as office paper and industrial paper; Advantages of using diatomaceous earth: The body is light and soft, with a fineness range of 120 to 1200 mesh. The addition of diatomaceous earth can make the paper smooth, light in weight, strong, and reduce stretching caused by humidity changes. In cigarette paper, the combustion rate can be adjusted without any toxic side effects. In filter paper, it can improve the clarity of the filtrate and accelerate the filtration rate. Paint and coating industry: various paint and coating fillers such as furniture, office paint, architectural paint, machinery, home appliance paint, oil printing ink, asphalt, automotive paint, etc;

Advantages of using diatomaceous earth: neutral pH value, non-toxic, with a fineness of 120 to 1200 mesh, light and soft constitution, making it a high-quality filler in paint. Feed industry: Additives for various feed sources such as pigs, chickens, ducks, geese, fish, birds, and aquatic products. Advantages of using diatomaceous earth: pH value is neutral and non-toxic, diatomaceous earth mineral powder has a unique pore structure, light and soft weight, large porosity, strong adsorption performance, and forms a light and soft color. It can be evenly dispersed in the feed and mixed with feed particles, making it difficult to separate and separate. After livestock and poultry eat, it promotes digestion and can adsorb bacteria in the gastrointestinal tract of livestock and poultry and excrete them, enhancing physical fitness and playing a role in strengthening muscles and bones, Aquatic products placed in fish ponds have improved water quality, good breathability, and increased survival rate of aquatic products. Polishing and friction industry: polishing brake pads in vehicles, mechanical steel plates, wood furniture, glass, etc; Advantages of using diatomaceous earth: strong lubrication performance. Leather and artificial leather industry: various types of leather such as artificial leather products.

Advantages of using diatomaceous earth 5: Strong sun protection, soft and light constitution, and high-quality filling material that can eliminate leather pollution in balloon products: light capacity, neutral pH value, non-toxic, light, soft 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.

The main advantages of folding and editing this paragraph

Diatomaceous earth coating additive products have the characteristics of high porosity, strong absorption, stable chemical properties, wear resistance, heat resistance, etc. They can provide excellent surface performance, compatibilization, thickening, and improved adhesion for coatings. Due to its large pore volume, it can shorten the drying time of the coating. It can also reduce the amount of resin used and reduce costs. This product is considered to be an efficient coating matte product with good cost-effectiveness, and has been designated as a product by many large international coating manufacturers, widely used in water-based diatomaceous mud.
