What is diatomaceous?

Diatomaceous earth is a biochemical sedimentary rock. It is deposited from the cell walls of diatoms. Its color is light yellow or light gray, its texture is soft and light, and it can be easily ground into powder. It has low density, is porous, rough, and highly absorbent. The typical chemical composition of oven-dried diatomaceous earth is 80 to 90% silica, 2 to 4% alumina (mostly due to clay minerals), and 0.5 to 2% iron oxides.

Diatomaceous earth is a poor conductor of heat, sound and electricity, so it can be used as a lightweight, insulating and soundproofing material. It is also used as a filter material for swimming pools, as a polishing material, and as an adsorbent for liquids, such as the adsorbent of nitroglycerin in the nitroglycerin explosive invented by Alfred Nobel, as well as insecticidal substances and so on. Diatomaceous earth can also be used as an insulating material.

Diatomite coating additive products have the characteristics of large porosity, strong absorption, stable chemical properties, wear resistance, and heat resistance. It provides excellent surface properties to coatings, compatibilizing, thickening and improving adhesion. Because it has a larger pore volume, it can shorten the drying time of the coating film. It can also reduce the amount of resin used and reduce costs. This product is considered to be a highly cost-effective matting powder product for coatings. It is used as a designated product by many large paint manufacturers in the world and is widely used in water-based diatom mud.
