Applications of zeolite in various fields
For many years, zeolite has been mainly used for blood purification in the medical field. In developed countries such as Europe and the United States, micronized zeolite has been hailed as a “natural medical device” in the medical field.
Because zeolite itself has a regular porous structure and small particle size, it can filter molecules, exchange cations, and adsorb heavy metal substances. Therefore, after zeolite enters the human body, it can adsorb and remove a variety of toxins, radioactive elements and other harmful metabolites in the human body.
In recent years, natural zeolite has been widely used in green building materials, petrochemical industry, soil improvement, sewage treatment, metallurgy, medicine, atomic energy industry and light industry, becoming an important new natural and environmentally friendly material in the national economy. Therefore, the development of natural zeolite and applications are attracting more and more attention.
1. In the petroleum and chemical industries: used as catalytic cracking, hydrocracking in petroleum refining and chemical alienation, reforming, alkylation and disproportionation of petroleum; gas and liquid purification, separation and storage agents; hard water softening and seawater desalination. Agent; special desiccant (dry air, nitrogen, hydrocarbons, etc.).
2. In the light industry: used in papermaking, synthetic rubber, plastics, resins, paint fillers and quality colors, etc. It is used as adsorption separation agent and desiccant in national defense, space technology, ultra-vacuum technology, energy development, electronic industry, etc.
3. In the field of green building materials: This is the largest application field of zeolite. According to statistics, two-fifths of the world’s zeolites are used in the building materials industry, which can effectively improve the performance of concrete; or used in wall decoration materials. Zeolites have strong adsorption capabilities and can absorb polar molecules such as H2O, NH3, H2S, CO2, etc. have high affinity and can still be effectively adsorbed even under conditions of low relative humidity, low concentration, and high temperature. 4. In agriculture: Zeolite can be used as a soil conditioner to maintain moisture, fertility, and adjust pH. In the production of chemical fertilizers and pesticides, zeolite can be used as filler and solidification dispersion medium.
5. In terms of environmental protection: Zeolite can be used to treat waste gas and waste water, remove or recover metal ions from waste water and liquid, and remove radioactive pollutants from waste water.
6. In medicine: Zeolite is used to measure the amount of nitrogen in blood and urine. Zeolite has also been developed as a health product for anti-aging and removing heavy metals accumulated in the body.
7. In supply: Zeolite is often used in the refining of sugar.
8. Raw materials for new wall materials (aerated concrete blocks): As solid clay bricks gradually withdraw from the stage, the application proportion of new wall materials has now reached 80%. Wall material supply companies use coal gangue, fly ash, ceramsite, Slag, light industrial waste, heavy construction waste, zeolite, etc. are used as main materials to actively develop new wall materials.
9. In chemical distillation or heating experiments: often used to prevent bumping. There are a large number of small pores in the structure of zeolite, which can be used as condensation nuclei of bubbles to make the reaction liquid boil smoothly. Bisque-fired porcelain pieces broken to the size of rice grains can be used instead.
10. It can be used as a fish and shrimp feed additive in aquaculture, and can also be used as fish pond construction materials to purify water quality. Ammonia filtration for fish hatcheries; biological filter media.
