Diatomaceous earth
25 kg/bag, in henan, leaching stage
Diatomaceous earth is a kind of product performance and advantages 】 【 biogenic siliceous sedimentary rocks. Mainly by the ancient diatoms and other tiny organisms such as radiolaria and sponge spicule bodies of siliceous parts, diatom content can reach 70% 90%. The main mineral composition is opal, followed by water mica, kaolin clay minerals and quartz, feldspar, organic matter, etc. Diatomite has strong adsorption ability, has the good filterability, bleaching, chemical stability and insulating isolation stays. Soluble in alkali, insoluble in acid except hydrofluoric acid.
Product scope of application 】 【 diatomite used as synthetic resin, chemical fiber, dye, paint, solvents, acids, electrolyte, glycerin filtering agent, such as carrier of fertilizers and pesticides, plastic, rubber, pesticide ideal filler, recovery of sodium thiocyanate filter aid, remove nylon decoloring with activated carbon in the solution, ammonium nitrate spheres of anticaking agent, etc. Also widely used in light industry, food, medicine, building materials, oil, paper making, environmental protection and other departments.
