Coating knowledge: do you really know the application of diatomite?

Core tips: 1 Introduction to diatomite The common English names of diatomite are "diatomite, diatomaceaeus earth, kieselguhr, infraral earth, Tripoli, and fossil mean" Diatomite is formed by the deposition of the remains of the ancient single-cell aquatic plant diatom The unique properties of this diatom form its skeleton with the free silicon that can absorb water, and then deposit after its end of life Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Home of coatings news: first, the English name of diatomite is commonly used, such as "diatomite, diatomaceous earth, kieselguhr, infrastructural earth, Tripoli, fossil mean" Diatomite is formed by the deposition of the remains of ancient single-cell aquatic plant diatoms The unique properties of this diatom form its skeleton with the free silicon that can absorb water After the end of its life, the diatomite deposit is formed under certain geological conditions According to the metallogenic conditions, there is a distinction between the light water lake diatomite and the salt water sea diatomite Diatomite is a kind of non-metallic clay mineral Its main chemical composition is amorphous silica (or amorphous silica), with a small amount of clay impurities and organic matter such as montmorillonite, kaolinite and quartz Under the microscope, diatomite presents different shapes of various algae, the size of a single algae varies from several microns to dozens of microns, and there are many nano pores on the inner and outer surfaces of the algae, which is the basic physical characteristics of diatomite different from other non-metallic clay minerals Diatomite has the characteristics of micro porous structure, small bulk density, large specific surface area, strong adsorption performance, good dispersion and suspension performance, stable physical and chemical properties, relatively incompressibility, sound insulation, extinction, heat insulation, insulation, non-toxic and tasteless and other excellent properties Diatomite can not be used in industry without the above characteristics of diatomite 2、 Application of diatomite A diatomite functional mineral filler: the product obtained by crushing, drying, air separation, calcining (or melting and calcining), then crushing, classifying, removing impurities, changing its particle size and surface properties, which can be added to some industrial products or used as one of the raw materials of industrial products, can improve and improve some properties of these products We call this diatomite the functional mineral filler B Diatomite filter aid: diatomite has porous structure, lower density, larger specific surface area, relative incompressibility and chemical stability Therefore, it is called the natural molecular name, which takes diatomite as the main raw material, after crushing, drying, separation, calcination, classification and slag removal, and changes its particle size distribution and surface properties to meet the requirements of filtration process We call this kind of filter media which can improve the quality and efficiency of filtration diatomite filter aid C Diatomite heat insulation brick is the best hard heat insulation product under medium and high temperature conditions, so it is widely used in various industrial kilns in iron and steel, non-ferrous metals, non-metallic minerals, electric power, coking, cement and glass industries Under this working condition, it has superior performance that other heat insulation materials can't match D Diatomite particle adsorbent: it has the properties of irregular particle shape, large adsorption capacity, good strength, fire protection, non-toxic and tasteless, no dust, no dispersion after water absorption (oil) and easy recovery after use Therefore, (1) it is used as anti caking agent (or anti caking agent) in deoxidizer for food preservation; (2) it is used as desiccant in electronic instruments, precision instruments, medicine, food and clothing; (3) it is used in environmental protection In the project, it is used as absorbent of harmful infiltration liquid on the ground; (4) in golf course, baseball field and lawn, it is used as soil conditioner or improver to improve the applicability of athletes to the site due to climate change and improve the survival rate and pruning rate of turf; (5) in pet breeding industry, it is used as bedding for cats, dogs and other pets, commonly known as "cat sand" E Diatomite catalyst carrier: vanadium catalyst carrier, nickel catalyst carrier, etc Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
