Diatomite

Classification：Sedimentary Rock

A light colored sedimentary rock consisting mainly of siliceous crust of diatoms. The diatomite is a soft, fragile rock. Most diatomaceous earth forms under Yu Hai, and some of them are formed in lakes.

Diatomite is a siliceous rock, mainly distributed in China, the United States, Denmark, France, Romania and other countries. It is a biogenic siliceous sedimentary rock, which is mainly composed of the remains of ancient diatoms. Its chemical composition is mainly SiO2. It can be expressed by SiO2. NH2O, and its mineral composition is Opal and its variety. China's Diatomite reserves are 3.2 million tons, with a long-range reserve of about 2000000000 tons, mainly in East China and Northeast China, with large scale and more reserves in Jilin (54.8%, of which Jilin province is the first in Asia in Linjiang city). Zhejiang, Yunnan, Shandong, Sichuan and other provinces are widely distributed, but the high quality soil is only concentrated in the Changbai Mountain area in Jilin. Most of the other deposits are 3~4 grade soil. Because of the high impurity content, they can not be directly and deeply processed.

Diatomite is a fossil diatom accumulation soil deposit formed by the single cell plant called diatom after 1 to 20 thousand years' accumulation. Diatom is one of the protists that first appeared on the earth. They live in seawater or lake water. It is this diatom that provides oxygen to the earth through photosynthesis, and promotes the birth of human beings and animals and plants.
The Diatomite is formed by the deposition of the remains of the single cell diatom diatom, which is unique in its ability to absorb free silicon from the water to form its bones. When its life ends, the Diatomite deposit is formed under certain geological conditions.
It has some unique properties, such as porosity, low concentration, larger specific surface area, relative incompressibility and chemical stability. It can be applied to paint and paint after grinding, sorting, calcining, airflow grading, and removing impurity in the processing procedure of the original soil. Additives and other industrial requirements.
Diatomite is a very important nonmetallic mineral. Because Diatomite has special physical and chemical properties, it is widely used in chemical production of catalyst carrier, paint, rubber, paper filling material, filter and bleaching agent in food industry, heat insulation, sound insulation material, and oil refining, ceramics, glass, steel, metallurgy heat treatment, etc.

Chemical composition:
The chemical composition of Diatomite is mainly SiO2, which contains a small amount of Al2O3, Fe2O3, CaO, MgO and organic matter.

Physical properties:
The density of Diatomite is 1.9 - 2.3g/cm3, the bulk density is 0.34 - 0.65g/cm3, the specific surface area is 40 - 65m/g and the pore volume is 0.45 - 0.98M. The water absorption rate is 2 to 4 times of its own volume, and the melting point is 1650C - 1750 C. The special porous structure can be observed under the electron microscope.

Application scope:
Diatomite's application range of industrial fillers: agricultural and pharmaceutical industry: wettable powder, dry land herbicide, paddy field herbicide and various biological pesticides.
The application of Diatomite has the advantages of 1: pH neutral, non-toxic, good suspension performance, strong adsorption performance, light bulk density, oil absorption rate of 115%, fineness in 325 mesh ---500 mesh, good mixing uniformity, no blockage of agricultural machinery pipeline when used, which can moisturize, loose soil, prolong the effect of fertilizer effect and prolong the effect of crop growth. Compound fertilizer industry: fruit, vegetables, flowers and compound fertilizer and other crops. The advantages of Diatomite are: strong adsorption capacity, light bulk density, uniform fineness, pH neutral, non-toxic and good mixing uniformity. Diatomite can be used as an efficient fertilizer to promote crop growth and soil improvement. Rubber industry: vehicle tire, rubber tube, triangle belt, rubber rolling, conveyor belt, automobile foot pad and other rubber products filler. Application of Diatomite advantages: it can obviously enhance the rigidity and strength of the product, the settlement volume is 95%, and it can improve the chemical properties of the products, such as heat resistance, wear resistance, heat preservation, aging resistance and so on. Building insulation industry: roof insulation, insulation bricks, calcium silicate insulation material, porous coal stove, sound insulation and fireproof decoration board and other insulation, insulation, sound insulation building materials, wall sound insulation decorative board, floor tiles, ceramic products and so on;
With the advantage of Diatomite, 2:Diatomite should be used as additive in cement, adding 5%Diatomite in the cement production can improve the strength of ZMP, and the activity of SiO2 in cement can be used as a dangerous cement. Plastics industry: life plastic products, building plastic products, agricultural plastics, windows and doors plastics, all kinds of plastic pipes, and other heavy and light industrial plastic products.
The advantages of Diatomite are 3: excellent extensibility, high impact strength, tensile strength, tearing strength, good quality in soft soft and soft, good press strength and so on. Paper industry: all kinds of paper, such as office paper, industrial paper, and so on.
The advantages of algal soil: soft and soft in the range of 120 to 1200 orders, Diatomite can make paper smooth, light weight, good strength, reduce the change of humidity, adjust the burning rate in cigarette paper, without any toxic side effects, and improve the clarity of filtrate in filter paper, and speed up the filtration speed. Paint and coatings industry: all kinds of paint and paint filler for furniture, office paint, building coating, machinery, home appliance paint, oil print ink, lehr, automobile paint and so on.
The application advantages of Diatomite 4: pH value neutral, non-toxic, fineness of 120 mesh to 1200 mesh, the body soft, belongs to the quality of paint filler. Feed industry: pig, chicken, duck, goose, fish, bird, aquatic product and other feed additives. Diatomite advantages: pH neutral, non-toxic, Diatomite mineral powder has a unique pore structure, weight light and soft, large porosity, strong adsorption performance, formation of light and soft color, block into feed can be evenly dispersed, and mixed with feed particles, not easy to separate precipitation, livestock and poultry food to promote digestion, and can be livestock and poultry intestines The bacteria of the gastric tract were discharged after the absorption of the bacteria in vitro, strengthening the physique, strengthening the strengthening of the bone and strengthening the bone. The water quality of the aquatic products became clear in the pond and the air permeability was good, and the survival rate of the aquatic product was improved. Polishing and friction industry: brake pad polishing, mechanical steel plate, wood furniture, glass and so on. The advantage of applying Diatomite is that the lubrication performance is strong. Leather, artificial leather, leather and so on.
Application of Diatomite 5: strong sunscreen, soft and soft, can eliminate the quality fillers of leather contaminated steam ball products: light capacity, pH value neutral, non-toxic, light soft, smooth, good strength, sun protection against high temperature. Diatomite is applied in coatings, paint, sewage treatment and other industries.

The main advantages:
Diatomite coating additive products, with high porosity, strong absorbability, stable chemical properties, wear-resistant and heat-resistant, can provide excellent surface properties, compatibilization, thickening and adhesion for the coatings. Because of its large pore volume, the coating can shorten the drying time. It can also reduce the amount of resin and reduce the cost. The product is considered to be a kind of high efficiency and cost-effective coating for high efficiency coatings. It has been widely used in water based diatom mud as a designated product by many large paint producers in the world.
