Zeolite Molecular Sieves have the structure and characteristics of crystals, the surface is a solid skeleton, and the internal holes have the function of adsorbing molecules. There are pores connected to each other, and molecules pass through the pores channels. Due to the crystalline nature of the pores, the pore size distribution of molecular sieves is very uniform.
Molecular sieves selectively adsorb molecules according to the size of the holes in their crystal, that is, they adsorb molecules of a certain size and repel molecules of larger substances, so they are figuratively called "molecular sieves."
5A Molecular Sieve is commonly known as Ca molecular sieve, can adsorb any molecule with diameter less than 5 angstroms. Mainly used in n-isomeric hydrocarbon separation, PSA separation, and co-adsorption of water and carbon dioxide. With high selective adsorption and fast adsorption speed, Chemequip 5A molecular sieve is especially suitable for pressure swing adsorption (PSA) industry, which can adapt to any size of oxygen, hydrogen, carbon dioxide and other gas production PSA devices.

Zeolite is the general term of zeolite mineral, which is a kind of aqueous alkali metal or alkaline earth metal aluminum silicate mineral. The mineral characteristics of zeolite are divided into frame, flaky, fibrous and unclassified four types. The characteristics of the pore system are divided into one-dimensional, two-dimensional and three-dimensional systems. Any zeolite is made up of silica tetrahedron and aluminum oxide tetrahedron.

Zeolite has the properties of adsorption, ion exchange, catalysis, acid and heat resistance, so it is widely used as adsorbents, ion exchangers and catalysts, and can also be used for gas drying, purification and sewage treatment. Used as a soil conditioner in agriculture, it can protect fertilizer, water, and prevent pests and diseases. Zeolite also has "nutritional" value. Adding 5% of zeolite powder to the feed can speed up the growth of poultry and livestock, have a strong body and have fresh meat and a high egg production rate. In terms of environmental protection, it is used to treat waste gas and wastewater, remove or recover metal ions from wastewater and waste liquid, and remove radioactive pollutants in wastewater.
Due to the porous silicate nature of zeolite, there is a certain amount of air in the pores. It is often used as an anti-riot boiling agent. It is widely used in the petroleum and chemical industries, and in the light industry for papermaking, synthetic rubber, plastics, and resins. , Paint filler and quality color, etc. In national defense, space technology, ultra-vacuum technology, development of energy, electronic industry, etc., it is used as an adsorption separator and desiccant. In the building materials industry, it is used as a cement hydraulically active admixture to burn artificial lightweight aggregates to make lightweight and high-strength plates and bricks. In medicine, zeolite is used for the determination 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.
