Origin of Diatomite

Origin of Diatomite

The previous life of diatomite is a plankton called diatom. It is a single-cell algae that lived in water hundreds of thousands of years ago. Diatoms are widely distributed and can be found in the sea, fresh water, soda water, soil and wet surfaces. Most of them live in open ocean waters. Of course, some live on seabed gravel like a membrane, which can survive only in a humid atmosphere. Diatoms forming diatomite minerals mainly come from the ocean. After several years of growth, diatoms will form porous walls in the earth's crust, but they will not form solid diatoms after their life cycle is over.


Diatomite characteristics

Diatomite is a kind of siliceous rock. Because it is formed by the accumulation and evolution of ancient diatom remains, it also belongs to a biogenic siliceous sedimentary rock. Its chemical composition is mainly SiO2, and its chemical and physical properties are stable, which is also the main reason why the service life of diatomite made into diatom mud can be up to 20 years. At the same time, diatomite is also porous, with a porosity of more than 90%, and the number of micropores is thousands of times that of activated carbon. This unique structure is called "molecular sieve" and has strong adsorption performance. When diatomite is refined into diatom mud, this unique structure is perfectly preserved, and harmful gas molecules such as formaldehyde and benzene series free in the air are difficult to escape the pursuit of this big net.


Diatomite applicable industry

In China's industrial manufacturing industry, there is no lack of diatomite. The selected and processed diatomite products are widely used as filter aids and adsorbent materials, and have made outstanding contributions in many fields such as food, medicine, daily chemicals, nuclear waste and sewage treatment. For example: beer production filtration, drinking water purification, plasma and medical injection filtration, and even now diatomite products can be seen in the beauty and skin care products manufacturing industry. Of course, it also includes our diatom mud industry.


Present situation of diatomite reserves in China

China's Diatomite reserves are 320 million tons, with prospective reserves of more than 2 billion tons. It is mainly concentrated in East China and Northeast China, of which Jilin has a large scale and more reserves (54.8%, of which the proved reserves in Linjiang City, Jilin Province account for the first in Asia) Although Zhejiang, Yunnan, Shandong, Sichuan and other provinces are widely distributed, the high-quality soil is mainly concentrated in the Changbai Mountain Area of Jilin, so Jilin is also the largest province of diatom mud industry in China.

Tracing back to the source, when we understand diatomite, we also fundamentally understand diatom mud, and have more trust and love for the powerful environmental protection performance of diatom mud. Before diatom mud was used as wall material, scientists conducted long-term research and development on the characteristics and functions of diatomite. It was not put into production by enterprises until it was fully confirmed that it was safe and harmless and conducive to purifying indoor air. Finally, it was accepted by consumers and the market in the process of continuous development
