4A Zeolite is a crystalline material prepared by calcination and hydrothermal synthesis using kaolin or other aluminosilicate minerals as raw materials. It has a unique crystal structure with a pore size of 4 angstroms (4A), which can effectively screen and adsorb molecules, making it of great application value in many fields.
Main properties
1. Adsorption: 4A zeolite has a strong adsorption capacity for water molecules and is often used as a desiccant.
2. Ion exchange capacity: It can replace phosphates in detergents and reduce environmental pollution.
3. Thermal stability: 4A zeolite has excellent thermal stability and is suitable for applications in high temperature environments.
Application areas
1. Detergent industry: As an environmentally friendly detergent, 4A zeolite performs well in removing hard water ions.
2. Gas separation and purification: Used to adsorb and separate specific gas molecules, such as oxygen and carbon dioxide.
3. Chemical catalyst: Used as a catalyst or catalyst carrier in certain chemical reactions.
Preparation method
4A zeolite is usually prepared by calcining kaolin, which is obtained by calcining kaolin raw materials at high temperature, treating them with alkali and hydrothermal crystallization.
4A zeolite powder is widely used in industry and daily life due to its excellent performance and environmental advantages, and is an important research direction in modern materials science.
