Zeolite was first discovered in 1756. Swedish mineralogist Kronsti discovered that a class of natural aluminosilicate ores would boil when burned, hence the name "zeolite". There are more than 30 kinds of zeolites found in nature, the more common ones are analcite, chabazite, calcium zeolite, heuenite, sodium zeolite, mordenite, pyroxene, etc., all of which contain calcium and sodium.

Zeolite composition

Zeolite is a hydrous alkali metal or alkaline earth metal aluminosilicate mineral formed by volcanic eruptions over hundreds of millions of years.

Zeolite Properties

Its interior is full of tiny pores and channels, which is much more complex than a honeycomb. One cubic micron has 1 million nano-scale pores! Zeolite has a huge specific surface area, and the surface area of one gram of modified zeolite powder is equivalent to the area of a football field.

Zeolite use

Natural zeolite is an emerging material, which is widely used in environmental protection, green building materials, daily light industry, agricultural breeding, national defense and military industry, medical care and other industries, and its uses are constantly being developed.

What substances can zeolite adsorb?

The pore size of zeolite is about 1 nm or less, and the minimum diameter of the molecule is about 0.28 nm. Therefore, zeolite can adsorb all molecules between 0.28nm-1nm, including organic and inorganic molecules. However, because the pore size of each zeolite is different, the adsorption peaks are different. The smaller molecules that can be adsorbed in water, such as methanol and ammonia, are in the adsorption range. Most of these substances are substances outside the processing range of protein and activated carbon.

What are the application areas of zeolite?

Application of zeolite in household

▶ In terms of green building materials, the wall materials produced by zeolite are pure natural and zero pollution, which can also purify indoor air pollution problems and release negative ions for a long time.

▶ In terms of air purification, zeolite can convert automobile exhaust into NOx. It can also be used to purify harmful gases such as formaldehyde and VOC in home decoration, and can also remove industrial waste gas and reduce odor and odor in livestock farms.

Application of Zeolite in Light Industry

▶ In the light industry, zeolite can be used in papermaking, synthetic rubber, plastics, resins, coatings, toothpaste fillers and quality colors. It can also be used in refrigerator production to improve refrigeration efficiency. Used in plastics, it can improve the antistatic properties and light resistance of plastics. It can be used in ceramic production to improve the covering power of the glaze and reduce the firing temperature of ceramics. In addition, zeolite can also be used as a bleaching agent and a powder carrier, and can also be used in the refining of sugar.

Application of Zeolite in Cosmetics

▶ In beauty cosmetics, zeolite can be used in handmade soaps, facial masks, face creams, hand soaps, body washes and other daily cosmetics. It can not only effectively clean the skin, but also absorb the heavy metals left by other cosmetics, and also provide the skin with the rare mineral nutrients needed by the skin.

Application of Zeolite in Petrochemical Industry

▶ Natural zeolite is an emerging material, which is widely used in industry, agriculture, national defense and other sectors, and its use is in the petroleum and chemical industries, zeolite is used for catalytic cracking, hydrocracking and chemical isomerization of petroleum refining reforming, alkylation, disproportionation. Gas, liquid purification, separation and storage agent. Hard water softener, seawater desalination agent. Special desiccants (dry air, nitrogen, hydrocarbons, etc.). Preparation and synthesis of styrene, ethylbenzene and cumene, linear alkyl benzene, caprolactam, propylene oxide, etc. Still developing.

Application of Zeolite in Military Aviation

▶ In national defense, space technology, ultra-vacuum technology, energy development, electronic industry, etc., zeolite can be used as CO2 adsorbent, gas desiccant, rocket ignition agent, storage of atomic energy reactor fission reaction and nuclear reaction in spacecraft and submarines Carbon dioxide and water are removed from the device.

Application of Zeolite in Agriculture

▶ In the livestock industry, it can be used as a feed (pig, chicken) additive and deodorant, etc., which can promote the growth of livestock and improve the survival rate of chickens. In aquaculture, zeolite can be used as a feed additive for fish, shrimp and crab. Zeolite contains a variety of macro and trace elements necessary for the growth and development of fish, shrimp and crab. These elements are mostly in the form of exchangeable ions and soluble bases. It is easy to be absorbed and utilized, and it also has a variety of catalytic functions of biological enzymes. Therefore, the application of zeolite in fish, shrimp and crab feeds has the functions of promoting metabolism, promoting growth, enhancing disease resistance, improving survival rate, regulating animal body fluids and osmotic pressure, maintaining acid-base balance, and purifying water quality. Anti-mildew effect.

Processing process

Zeolite powder is widely used. In the zeolite processing process, the most important part is the grinding process. Different grinding equipment can be selected according to the fineness requirements of the final powder. CLIRIK provides you with Raymond mills, ultra-fine mills, vertical mills, etc., which can meet the configuration requirements of zeolite powder processing production lines under different production conditions.
