Zeolite molecular sieve basic traits of fold

And structure characteristics of molecular sieves 4a has a crystal surface as the solid skeleton, the internal cavity can have the effect of adsorbed molecules. Cavity between a channel are connected, molecules by the channel. As a result of the cavity clean properties, molecular sieve pore size distribution is very uniform. zeolite adsorbent according to the crystal to selective adsorption of molecules, the size of the internal cavity is adsorbed molecules of a given size and reject material larger molecules.

Zeolite molecular sieve according to its hole or channel system can be divided into the hole, the hole (mesoporous) and double Kong Feishi three categories.

Can be used for the pressure swing adsorption of oxygen enriched air separation.

The basic definition of zeolite molecular sieves

3a molecular sieves is crystallization of aluminum silicate metal salt hydrate, its chemical general formula is: Mx/m [(AlO2), x (SiO2), y] zH2O. M on behalf of the cation, M said its valence number, z said water hydration, x and y are integer. molecular sieve siliporite is activated, the water molecules are removed, the rest of the atoms form cage structure, aperture is 3 ~ 10 & Aring; . Crystals have many size of zeolites hole, hole there are many between the diameter of the hole (also called "window"). Because of the molecular sieve can be smaller than the aperture molecular adsorption into the hole, and to exclude is larger than the aperture of the molecules in the hole, have the effect of molecular sieving, so named molecular sieve. Zeolite molecular sieve can exist in the nature, artificial synthesis from the 1970 s.

natural gas separation is crystallization of aluminum silicate metal salt hydrate, its chemical general formula is: Mx/m [(AlO2), x (SiO2), y] zH2O. M on behalf of the cation, M said its valence number, z said water hydration, x and y are integer. molecular sieve 13x is activated, the water molecules are removed, the rest of the atoms form cage structure, aperture is 3 ~ 10 & Aring; . Crystals have many size of zeolites hole, hole there are many between the diameter of the hole (also called "window"). Because of the molecular sieve can be smaller than the aperture molecular adsorption into the hole, and to exclude is larger than the aperture of the molecules in the hole, have the effect of molecular sieving, so named molecular sieve.

molecular sieve 13x apg

Cylinder with supporting the use of fluoride home is ideal for family drinking fluoride removal device.zeolite molecular sieves The fluoride removal filter also can be used with water plant fluoride device or devices supporting the use of fluoride for  molecular sieve 13x apg industrial use. Household fluoride fluoride filter device activation: Configure aluminum sulfate solution (3 liters of water, 0.3kg solid aluminum sulfate), alumina (AL2P3) fluoride removal filter into the solution, soak 5-10 hours discard dip solution (soaking appropriate mixing),  regeneration of molecular sieves  then washed with water 3-5 times, each about 2 liters of water, or adjust PH regeneration method, PH value control at 7.5. Activated alumina fluoride removal filter can be used continuously for 6-8 years, when the surface appears brown when the effect of fluoride removal significantly reduced, due to impurities in the water pollution in this series, so it's best to use three percent every six months once dilute hydrochloric acid, which methods of operation and regeneration same way.

the "molecular sieve powder" refers to the zeolite

In general, the "molecular sieve powder" refers to the zeolite synthesis After washing, the product after drying (sodium or potassium type, etc.), no activity; also some of the active zeolite component of the catalyst before forming a "molecular sieve powder ", is hydrogen, synthetic zeolite powder suppliers  there is the activity. Now zeolite powder original sub 3A4A5A and other industrial raw powder, and clay bowls direct participation after drying, burning can be made ​​of the appropriate molecular  zeolite molecular sieve sieve. General granular zeolite molecular sieve is made ​​from raw powder and binder forming system, molecular  activated molecular sieve zeolite powder is true, there is no relationship with the activity. A water content of 40% is called the original powder, dried to 20% moisture content, also known as raw powder. Strictly speaking, the moisture content of 2% or less of the original powder is activated powder.
