Product Description

Product Description

Diatomite is a fossil diatomite deposit formed after the death of a single celled plant called diatom and a accumulation period of about 10000 to 20000 years. Diatoms are one of the earliest protozoa on the earth. They live in seawater or lake water. They create 70% of the oxygen on the earth. During the growth process, it continuously absorbs the free silicon in the water to form a solid and porous cell wall. After the end of the diatom life cycle, the cell wall will not decompose and deposit to the underwater bottom. Diatomite is formed through crustal changes.

This diatomite is formed by the deposition of the remains of single celled aquatic chemical Book Plant diatom. The unique performance 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 deposit under certain geological conditions. It has some unique properties, such as porosity, low concentration, large specific surface area, relative incompressibility and chemical stability. After changing its particle size distribution and surface properties through processing processes such as crushing, sorting, calcination, air flow classification and impurity removal, it can be applied to a variety of industrial requirements such as coatings and paint additives.
It has the characteristics of non-combustion, sound insulation, waterproof, light weight, and heat insulation.

Product Application

1.Food filter aid. Diatomite has strong adsorption capacity, so it is used as filter aid in food industry to remove bacteria, impurities and peculiar smell.
2.In environmental protection industry, diatomite is used for sewage treatment.
3.In the construction industry, diatomite is used to make insulating bricks.
4.Coating Industry.The interior wall coating made of diatomite is non reflective and the indoor light is soft. This kind of wallpaper coated with diatomite is called "breathable wall".
5.Rubber Industry. Diatomite is used as filler in various rubber products such as vehicle tyres, rubber tubes, triangular belts, rubber rolling, conveyor belts, automobile foot pads and so on. It can obviously enhance the rigidity and strength of products, and improve the heat resistance, wear resistance, thermal insulation and anti-aging properties of products.
6.Agriculture. Diatomite as an insecticide has many advantages, such as non-toxic, tasteless, good insecticidal effect, no environmental pollution, ensuring grain storage quality and so on; Diatomite particles are used as soil improvers. They are a good carrier of fertilizer and water required by plants. They can effectively adjust the absorption and release of water according to soil humidity. They can also have the functions of moisture retention, air permeability and drying. They play a great role in plant root growth and water and soil conservation; Diatomite is widely used as adsorbent grain and seed storage.
7.In chemical industry, diatomite is used as catalyst carrier.
