Many people don’t know about diatomaceous earth or what kind of product it is. What is its nature? So where can diatomaceous earth be used? Next, the editor of the diatomite filter disc will give you a detailed explanation!

   Silica thin soil is made by pulverizing, grading, and calcining the soil formed by piling up the remains of organisms called diatoms.

   Its main component is amorphous silicon dioxide ice, with a small amount of clay impurities, and it is white, yellow, gray, or pink. Because of its good thermal insulation properties, it is used as a thermal insulation material.

   Diatomaceous earth is a white to light gray or beige porous powder. It is light in weight and has strong water absorption. It can absorb water 1.5 to 4 times its own mass. Diatomaceous earth is insoluble in water, acids (except hydrofluoric acid) and dilute alkali, but soluble in strong alkali.

   Diatomite Toxicity: ADI is not specified. The product is not digested and absorbed, and the refined product of diatomaceous earth is very low in permeability.

If the silica in diatomaceous earth is inhaled, it will harm the human lungs and may cause silicosis. The silica in diatomaceous earth is considered to have low toxicity, so when the concentration of silica exceeds At the allowable level, respiratory protection measures are required.

  So what are the applications of diatomaceous earth?

   1. Diatomaceous earth is an excellent filter aid and adsorbent material, which is widely used in food, medicine, sewage treatment and other fields, such as beer filtration, plasma filtration, and drinking water purification.

  2, make cosmetics, facial masks, etc. The diatomaceous earth mask uses the adsorption function of diatomaceous earth to absorb impurities in the skin, and has the effect of deep maintenance and whitening. People in some countries often use it to cover the whole body for body beauty, which has the effect of nourishing skin and skin care.

   3. Processing nuclear waste.
