What is the quality of diatomaceous earth

Release time:2021-04-29 14:51:28  Number of views:

Diatomaceous earth has a quality grade, and among the existing diatomaceous earth minerals, only the Rombok deposit in California, USA and the Ma'anshan deposit in the Baishan area of Jilin Province, China are world-class diatomaceous earth deposits. It is a high-quality, abundant, and high-quality mineral deposit in diatomaceous earth minerals. In response to the needs of consumers, China has formed various styles of decorative effects such as yin and yang carving, silk screen printing, and artistic hand painting. The wall material of diatomaceous earth and diatomaceous mud in China are consistent in terms of environmental protection and health functions, but it can be said that the production and quality of diatomaceous earth in many regions of China are better than those of foreign countries.

The natural diatomite is not a good filter aid. It must undergo chemical treatment, high temperature burning, crushing, water washing, drying, grinding and screening to remove organic matter and other impurities, improve Granularity, porosity and surface characteristics, and obtain good filtration performance.

Diatomite is a kind of biochemical sedimentary rock composed of cell walls of Aquatic plant called diatoms thousands of years ago. It has numerous pores and multiple pores. Its powder particle size is very small. About 90% of its diameter is 2-100 microns, which is permeable pores. Its main component is silicon dioxide, which accounts for 85% -90%. It has chemical stability, high temperature resistance, insolubility, and non-toxic properties. This porous particle provides great filtration function, which can remove particles below 1-0.1 micrometers (including microorganisms and bacteria) and contain the fission products.
