Zeolite

Zeolite is an ore that was first discovered in 1756. Swedish mineralogist Kronsti discovered a type of natural aluminosilicate ore that undergoes boiling when burned, hence the name "zeolite". In Greek, it means "boiling" or "stone".

The general chemical formula of zeolite is AmBpO2p · nH2O, with a structural formula of A (x/q) [(AlO2) x (SiO2) y] · n (H2O), where A is a cation such as Ca, Na, K, Ba, Sr, B is Al and Si, p is the cationic valence, m is the number of cations, n is the number of water molecules, x is the number of Al atoms, y is the number of Si atoms, (y/x) is usually between 1 and 5, and (x+y) is the number of tetrahedra per unit cell.

Zeolite is a general term for zeolite minerals, which are a type of hydrated alkali or alkaline earth metal aluminosilicate mineral. It is a microporous aluminosilicate mineral commonly used as a commercial adsorbent and catalyst.

Natural zeolite is an emerging material widely used in industries, agriculture, national defense, and other sectors, and its applications are constantly being explored. Zeolite is used as an ion exchange agent, adsorption and separation agent, desiccant, catalyst, and cement mixing material. In the petroleum and chemical industries, catalytic cracking, hydrocracking, and chemical isomerization, reforming, alkylation, and disproportionation of petroleum are used for petroleum refining; Gas and liquid purification, separation, and storage agents; Hard water softening and seawater desalination agents; Special desiccants (dry air, nitrogen, hydrocarbons, etc.). Used in the light industry for papermaking, synthetic rubber, plastics, resins, coating fillers, and quality colors. Used as an adsorbent and desiccant in areas such as national defense, space technology, ultra vacuum technology, energy development, and electronics industry. In the building materials industry, it is used as a cement hydraulic active admixture, fired with artificial lightweight aggregates, and made into lightweight high-strength boards and bricks. Used as a soil amendment in agriculture, it can maintain fertilizer, water, and prevent diseases and pests. In the poultry and livestock industry, additives and deodorants used as feed (pigs, chickens) can promote livestock growth and improve the survival rate of chicks. In terms of environmental protection,  it is used to treat exhaust gas and wastewater, remove or recover metal ions from wastewater and waste liquid, and remove radioactive pollutants from wastewater.

Zeolite is used in medicine for the determination of nitrogen in blood and urine. Zeolite has also been developed into health products for anti-aging and removal of accumulated heavy metals in the body.

Zeolite is commonly used for refining sugar in production.

New wall materials (aerated concrete blocks) raw materials

With the gradual withdrawal of solid clay bricks from the stage, the application proportion of new wall materials has reached 80%. Wall material production enterprises mainly use coal gangue, fly ash, ceramic particles, slag, light industrial waste, heavy construction waste, zeolite, etc., and actively develop new wall materials.

In chemical distillation or heating experiments, it is often used to prevent boiling, because the structure of zeolite has a large number of small pores that can act as condensation nuclei for bubbles, making the reaction liquid boil smoothly. You can replace it with plain fired porcelain pieces that are broken to the size of rice grains.

Zeolite, as a feed additive, has high safety and positive effects on improving pig growth performance and disease prevention. Zeolite also has the characteristics of large distribution and easy mining. Therefore, as an efficient and low-cost feed additive, it can be more widely used in pig production. At the same time, zeolite can also improve social issues such as food safety, environmental protection, and animal welfare in pig farming, making pig farming more in line with the requirements of the times. Existing problems: Further research is needed to investigate the relationship between the proportion of different types and purities of zeolites in feed and pig growth and disease prevention, as well as the specific physiological mechanisms by which zeolites hinder various toxins in disease prevention.

1. As a feed additive for fish, shrimp, and crabs.Zeolite contains various constant and trace elements necessary for the growth and development of fish, shrimp, and crabs. These elements mostly exist in exchangeable ion states and soluble salt forms, which are easily absorbed and utilized. At the same time, they also have various catalytic effects of biological enzymes. Therefore, the application of zeolite in fish, shrimp, and crab feed has the effects of promoting metabolism, promoting growth, enhancing disease resistance, improving survival rate, regulating animal body fluids and osmotic pressure, maintaining acid-base balance, purifying water quality, and having a certain degree of anti mold effect. The amount of zeolite powder used in fish, shrimp, and crab feed is generally between 3% and 5%.

2. As a water quality treatment agent.Zeolite has unique adsorption, screening, exchange of cations and anions, and catalytic performance due to its numerous pore sizes, uniform tubular pores, and large internal surface area pores. It can absorb ammonia nitrogen, organic matter, and heavy metal ions in water, effectively reduce the toxicity of hydrogen sulfide at the bottom of the pool, regulate pH value, increase dissolved oxygen in water, provide sufficient carbon for the growth of phytoplankton, improve the intensity of water photosynthesis, and is also a good trace element fertilizer. Each kilogram of zeolite applied to the fishing pond can bring in 200 milliliters of oxygen, which is slowly released in the form of microbubbles to prevent water quality deterioration and fish from floating. When using zeolite powder as a water quality improver, the dosage should be applied at a water depth of one meter per acre, plus about 13 kilograms, and sprinkled throughout the entire pool.

3. Use as materials for constructing fishing ponds.Zeolite has many pores inside and extremely strong adsorption capacity. When repairing fishing ponds, people abandon the traditional habit of using yellow sand to lay the bottom of the pond. Instead, yellow sand is laid on the bottom layer, and boiling stones with the ability to exchange anions and cations and adsorb harmful substances in the water are scattered on the top layer. This can keep the color of the fishing pond green or yellow green all year round, promote the rapid and healthy growth of fish, and improve the economic benefits of aquaculture.
