Molecular sieve is a kind of material with uniform pore size, and its pore size is similar to that of general molecule. The application of molecular sieve is very wide, can be used as an efficient desiccant, selective adsorbent, catalyst, ion exchange, etc., but the use of chemical raw material synthesis of molecular sieve cost is high. The commonly used molecular sieve as crystalline silicate or aluminosilicate, is made of silicon oxygen tetrahedron or tetrahedral bond connected by oxygen bridge and the formation of molecular size (usually 0.3~2 nm) pore and cavity system, and has the ability of fluid molecular sieving different sizes due to adsorption of molecules of different size and shape.
Molecular sieve powder crystal, with metallic luster, hardness is 3 ~ 5, the relative density is 2 ~ 2.8, the color of natural zeolite, zeolite is white, insoluble in water, thermal stability and acid resistance increased with the increase of SiO2/Al2O3 composition ratio. Molecular sieve has large surface area, up to 300 ~ 1000m2/g, within the crystal surface height of polarization, as a kind of efficient adsorbent, is also a kind of solid acid, acid concentration and acid strength of surface is very high, can cause the catalytic reaction of carbonium ion type. When the composition of the metal ions and other ions in the solution can be adjusted, the pore size can be adjusted to change the adsorption properties and catalytic properties, thus making different performance of the molecular sieve catalyst.25kg/ package.Unit price: 20 yuan /kgSpecifications:3A4A 5A 10X 13X Wholesale telephone: 15838227230【腾龙3A分子筛主要应用】符合中空玻璃所有性能指标以及不对其物理和化学性质有任何影响的分子筛，才够资格称为中空玻璃专用分子筛。达到这一要求的只有3A分子筛。
