Diatomite filter aid is a chemical raw material that is produced through various processing steps such as expansion, grinding, classification, and mixing of the natural mineral diatomite. It has functions such as filtration, adsorption, and precipitation. In fact, diatomaceous earth is a type of material; when used in paints, it has the ability to absorb toxic gases in the air. It is very environmentally friendly, and its price is also low, around 30 per kilogram. Diatomite is a rock with a biological structure. It is mainly composed of 80–90% diatom frustules, with some reaching over 90%. The main consumers of silica in seawater and lake water are diatoms, which form diatomaceous mud. Diatomite is formed during the petrifaction stage in the diagenetic process. Diatom frustules are composed of opal; as diatoms grow and reproduce, they absorb colloidal silica from water, which gradually transforms into opal. The higher the content of diatoms in diatomite, and the fewer the impurities, the whiter its color and the lighter its weight. Its specific gravity is generally between 0.4 and 0.9. Due to the numerous pores in the diatom frustules, diatomite has a porous structure; its porosity ranges from 90% to 92%, giving it strong water absorption properties and a sticky texture. The small size of the diatom particles makes diatomite fine and smooth. Diatomite does not dissolve in acids such as HCl, H2SO4, and HNO3, but it does dissolve in HF and KO. The above is all the information shared by Jilin Yuantong Diatomite Manufacturer.
