Diatomaceous earth is the remains of ancient single-celled diatoms. Its characteristics: light weight, porous, high strength, wear resistance, insulation, heat insulation, adsorption and filling and other excellent properties. Has good chemical stability. It is an important industrial material for heat insulation, grinding, filtration, adsorption, anticoagulation, demoulding, filling, carrier, etc. It can be widely used in metallurgy, chemical industry, electric power, agriculture, fertilizer, building materials and insulation products and other industries. It can also be used as industrial functional filler in plastics, rubber, ceramics, papermaking and other industries.
Product application introduction:
Diatomaceous earth filler:
1. Special diatomite energy-carrying filler for centrifugal casting (tube) coating
Centrifugal casting (tube) coatings formulated with appropriately processed diatomaceous earth, binders, suspending agents and additives can adjust the thermal resistance of the casting system and control the cooling rate of the casting (tube), thereby achieving Extend the life of the mold used in centrifugal casting by hot mold method and ensure that the metallographic structure and mechanical properties of the castings meet the requirements
2. Diatomaceous earth functional filler for building exterior (interior) wall coatings
In coatings, the unique porous particle structure of diatomite can make the smooth coating highly rough and produce a matte effect. Not only that, diatomite can also adjust and balance the adhesion between the coating and the base surface. Additionally, sticky paints dry quickly due to the porosity of diatomaceous earth.
3. Diatomite functional filler for rubber industry
The unique particle structure of diatomite can make it act as a semi-reinforcement material in products such as polysilicone rubber and mechanical rubber. Partially replaces carbon black.
4. Pesticide industry:
The advantages of using diatomite as pesticide powder filler: neutral pH value, non-toxic, good suspension performance, strong adsorption performance, light bulk density, oil absorption rate 135, the fineness is between 325 mesh and 500 mesh, and the mixing uniformity is good. It will not block when farmers use it. It can insulate the soil, loosen the soil, extend the efficacy of medicine and fertilizer, improve the soil, and promote the growth of crops.
5. Compound fertilizer industry:
Compound fertilizer for fruit trees, vegetables, flowers and various crops. Advantages of applying diatomite: strong adsorption performance, light bulk density, uniform fineness, neutral PH value, non-toxic, good mixing uniformity. The application of diatomite in compound fertilizer can become a high-efficiency fertilizer, promote crop growth, improve soil, etc. .
6. Plastic industry:
Living plastic products, construction plastic products, agricultural plastics, window and door plastics, various plastic pipes, and other light and heavy industrial plastic products.
Advantages of using diatomite: excellent extensibility, strong impact strength, c-tear strength, light weight, softness, good wear resistance, and excellent compressive strength.
7. Paper industry:
Cigarette paper, filter paper and various packaging papers, printing papers, household paper, office paper and other paper-making papers are used as fillers.
Advantages of applying diatomite: light and soft, with fineness ranging from 120 mesh to 1200 mesh. Adding diatomite can make the paper smooth, light in weight, good in strength, and reduce stretching caused by changes in humidity. Swelling, the burning rate can be adjusted in cigarette paper without any toxic side effects, and the clarity of filtrate can be improved in filter paper and the filtration speed can be accelerated.
8. Paint industry:
Fillers for various paints and coatings such as furniture, office paints, architectural coatings, machinery, home appliance paints, mimeograph inks, asphalt, automobile paints, etc.
9. Feed industry:
Pigs, chickens, ducks, geese, pigeons, various fish, birds, and fillers for various feeds.
Advantages of applying diatomite: neutral PH value, non-toxic, diatomite mineral powder has unique pore structure, light and soft body, large porosity, strong adsorption performance, light and soft color, easy to mix It can be evenly dispersed in the feed and mixed with the feed particles. It is not easy to separate and precipitate. It promotes digestion after being eaten by livestock and poultry. It can also absorb and excrete bacteria in the gastrointestinal tract of livestock and poultry, enhance health, and strengthen muscles and bones. The effect is that when aquatic products are placed in fish ponds, the water quality becomes clearer, the air permeability is good, and the survival rate of aquatic products is improved.
10. Daily chemical industry: can be used as filler in toothpaste and cosmetics.
11 Building materials industry: It can be used as lightweight high-strength diatomite insulation bricks, microporous calcium silicate, raw materials for calcium silicate boards, asphalt pavement modifiers, additives for drilling cement, and cement mixers. material filler.

13. Application technology on roof surfaces: Diatomite is the best raw material for non-metallic heat insulation, sound insulation and thermal insulation. Its fire resistance can reach 1380 degrees Celsius. With the improvement of people's living standards, the problem of heat insulation on the roofs of high-rise buildings has not yet been well solved. After successful experiments in several high-rise buildings in Hangzhou and Shanghai, diatomaceous earth was used on the roofs as insulation layers, reducing the It reduces the temperature of direct irradiation and reduces the temperature difference between the roof and the ground floor. The operation is simple and convenient, the price is low, and the effect is good. The ex-factory price of 100 mesh diatomite raw materials is 260 yuan per ton. Can be 6-8 square meters, no need to add any other raw materials. Today, as new types of thermal insulation are constantly emerging, other new raw materials for thermal insulation products are also constantly being developed. However, the many special properties of diatomite itself cannot easily be replaced by other raw materials. Its production process and equipment are relatively simple. Our country is rich in diatomite resources, widely distributed, cheap, and widely used. Therefore, diatomite should be developed and utilized as a roof insulation material.
14. Flower industry: Diatomaceous earth can be used as a soil conditioner for flower cultivation to regulate the moisture and air in the soil, prevent root mold, root rot and death from exposure, and promote the effective growth of flowers. .
