Guide The diatom mud, diatom coating, inner wall material and other building functional materials with diatomaceous earth as a functional component flourished and flourished, showing extremely high application value in terms of thermal insulation, humidity regulation and formaldehyde removal. What is the difference between diatom mud processed by different processes of diatomaceous earth by calcination, calcination and non-calcination? In recent years, with the improvement of living standards of urban and rural populations, diatomite, diatom coatings, interior wall materials and other building functional materials with diatomite as functional components flourished and are in the ascendant, in thermal insulation, humidity regulation, formaldehyde Removal and other aspects show extremely high application value. In diatom mud as the current environmentally friendly home improvement material in the country, few people know that the origin of diatom mud is not China, but Japan. Japan is a country with a strong chemical industry, and their home improvement materials are basically environmentally friendly materials. For diatom mud, every household is basically used, and their diatom mud is basically developed with natural non-calcined diatomite, natural environmental protection, breathing and humidity control, rarely heard of formaldehyde pollution. What is the difference between diatomite roasting, calcination, and non-calcination, and what is the difference between diatom mud processed by different processes? Is non-calcined diatom mud really the best? The so-called roasting means that the temperature is strictly controlled at about 500 degrees Celsius, the diatomaceous earth is slowly heated, and calcined at a constant speed for more than 2 hours, which can retain the integrity of most pores of diatomaceous earth and good adsorption, and is slowly warmed up. Heating at a constant temperature, the removal of organic impurities is relatively thorough, and the whiteness is high and the particles are uniform. The functional main body of diatomite is diatom frustule, whose main chemical component is amorphous SiO2, and also contains a small amount of Al2O3, Fe2O3, CaO, MgO and organic matter. The roasting treatment can reduce or even eliminate impurities such as organic matter and carbonate, improve the purity and whiteness of the product, and also help to improve the chemical reactivity of the diatomaceous earth and improve the mechanical strength of the building materials. On the other hand, different roasting systems may also change the pore structure of diatomaceous earth to a certain extent, which will have a greater impact on the adsorption performance of diatomite. Calcination means that diatomaceous earth is added to a co-solvent and heated in a furnace at a high temperature of 900 to 1150 degrees for 10 minutes to 30 minutes, and the co-solvent is rapidly melted and bonded to the diatomaceous earth. Calcination can achieve less time and low cost. However, because the temperature is too high, it is difficult to control, and the diatomite is easily sintered and formed into balls. It needs to be ground again to break into the required fineness, causing secondary damage to the pores on the surface of the diatomaceous earth. Since the co-solvent melts and adheres to the surface of the diatomaceous earth to block the pores of the diatomaceous earth, the specific surface area of ​​the diatomaceous earth is lowered. And the high temperature of up to 1100 easily melts and disappears the micropores of the diatomaceous earth, the microporous structure of the diatom body is completely destroyed, part of the pore walls are crystallized and melted, and the polyporous structure of the diatomaceous earth is broken through to cause the adsorption property to be lowered. Non-calcined diatom mud refers to those minerals that are relatively natural and well maintain the natural characteristics of diatom mud. Non-calcined diatom mud is not subjected to high temperature calcination, and is distinguished from calcined diatomaceous earth by water washing, dispersing and sieving. The diatomite obtained by the multi-gravity field laminar centrifugal beneficiation and dry grading process can effectively separate the quartz , feldspar minerals and clays and some organic matter in the diatomite ore, and can be wet in the wet state. The diatomaceous earth is precisely graded to retain the natural functional properties of diatomite to a maximum extent, with larger specific surface area, higher porosity, larger pore volume, smaller pore size, and stronger adsorption and humidity control capabilities. Non-calcined diatom mud has a stronger environmental function than the same amount of calcined diatom mud because of its higher diatomaceous earth content. summary Non-calcined diatom mud is indeed more functional. But diatomaceous earth is divided into many types, including surface and underground mines. The general underground mines are all brown and must be mined and calcined to become diatom mud. At present, in view of the diatom mud industry, the diatom mud of most manufacturers is limited by the geographical gap of domestic diatomaceous earth. The mined minerals are mostly underground minerals, many magazines, and the color is not good. After the intervention, artificial intervention is also required. Calcination The diatomaceous earth purifies the whiteness, etc., so that the diatom mud that comes out is less functional. we can supply hydraulic/steering/transfer/piston/gear/ram pump for Terex 3305,Terex 3307,Terex TR50,Terex TR60,Terex TR100.The Terex Steering Pump plays a big role in the Terex steering system.Steering conforms to ISO 5010,SAE J53.
