Automobile Desiccation Molecular Sieve

structure characteristics of zeolite Automobile Desiccation Molecular Sieve 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. Due to the crystallization properties of cavity, 3a zeolite molecular sieve pore size distribution is very uniform. Molecular sieve on the basis of 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, so vividly called "molecular sieve".

The role of the double glazing desiccant

Strong ability of double glazing desiccant hygroscopic, used for gas purification processing, preservation should avoid direct exposure to the air. Stored for a long time and has moisture absorption of the molecular sieve before use should be recycled. double glazing window glass desiccant avoid oil and liquid water. When using, should try to avoid contact with oil and water. Industrial production in the drying process of gas, air, hydrogen, oxygen, nitrogen, argon, etc. With two adsorption dryer in parallel, a job, while the other can be regenerated. Alternating work and regeneration, to ensure the equipment run continuously. Dryer work at room temperature, air flushing regeneration under heated to 350 ℃.

The role of the molecular sieve drying

molecular sieve drying is a cubic lattice silicon aluminate compound, mainly composed of silicon aluminium by oxygen bridge connecting the empty skeleton structure, uniform in structure, there are a lot of aperture of concreted complete order, inner hole surface area is very big. In addition also contains electricity price lower metal ions and ionic radius is larger and combining state of water. Because the water molecules in the heated continuously losing, but crystal skeleton structure remains the same, has formed many of the same size of the cavity, the cavity has many of the same diameter pores is linked together, these small cavity diameter size uniform, can channel diameter smaller than the drying molecular sieve to the interior of the cavity, and the hole bigger than molecular excluded, so the molecules of different diameter size shape, the degree of different polarity molecules, the boiling point of different molecules, degree of saturation of different molecular separation, which have the function of the "screening" molecules, known as molecular sieve. Current molecular sieves in chemical industry, electronics, petrochemical, natural gas and other widely used in industry.

molecular sieve xh-5

molecular sieve xh-5 with a lot of white pellets capillary channel, there are many pores channel surface of these channels
Have a higher activity, to gas, vapor, liquid water has a selective adsorption ability. Dried under certain conditions
Depth of up to -70 ℃ below the dew point, in addition to water saturation can be heated at 175 ℃ -400 ℃ and resurrection, can many times,
Lubricants and other oils can also adsorb vapors from the contaminated oxygen, hydrogen, sulfur dioxide, and may make the catalyst or carrier.
Widely used in the drying device petrochemical, refining, electronics, ethylene, propylene, air, etc., the country has many hydrogen peroxide plant,
Fertilizer plant, oxygen plant and petrochemical refining units to use, and molecular sieve separation have achieved good results
.

Molecular sieve

Molecular Sieve High Voltage (typically 0.3~2.0 Nm) system of pores and cavities, which has the characteristics of screening molecules.However with molecular screen synthesis and application research of in-depth, researchers found has p aluminum acid salts molecular sieve dehydration process screen, and molecular screen of skeleton elements (Silicon or aluminum or p) also can by b, and Ga, and Fe, and Cr, and Ge, and Ti, and v, and Mn, and Co, and Zn, and Be and Cu, replaced, its channel and empty cavity of size also can reached 2 nm above, so molecular screen by skeleton elements composition can is divided into Silicon aluminum class molecular screen, and p aluminum class molecular screen and skeleton miscellaneous Atomic molecular screen;Divided by the pore size, pore size less than 2 NM, 2~50 nm and greater than 50 nm of molecular sieves are called micro-porous, mesoporous molecular sieves.Due to its large aperture, become good carriers for large molecular reactions, but wall thickness of mesoporous material is amorphous, its thermal stability and thermal stability are not meet the demanding conditions required petrochemical applications.

The advantage of Molecular sieve absorption

molecular sieve manufacturers ability is very strong, for gas purification, save should avoid direct exposure to the air.Stored for a long time and has moisture-molecular sieve regeneration should be carried out before use.Molecular sieve avoiding oil and liquid water.Should be used as far as possible avoid contact with oils and liquid water.Drying in mole sieve dehydration of industrial gases, air, hydrogen, oxygen, nitrogen, argon and so on.Adsorption dryer with two parallel, a job, while the other can be regenerated.Alternating work and regeneration, to ensure a continuous operation.Dryer working at room temperature, impact regeneration in a heated to 350 degrees.

Molecular sieve

Molecular Sieve High Voltage is a kind of cubic lattice Silicon aluminate compounds, mainly composed of silica-alumina by oxygen bridges to connect empty skeletal structure, there are many uniform pore size in the structure of pores and neat, and a large internal surface area of the cavity.Also contains the price lower and larger Ionic radius of metal ions and combined state of the water.Due to water molecular in heating Hou continuous to lost, but Crystal skeleton structure not variable, formed has many size same of empty cavity, empty cavity and has many diameter same of micro-hole connected, these tiny of cavities diameter size uniform,activating molecular sieves can put than channel diameter small of molecular adsorption to cavities of internal in the to, and put than channel big have molecular exclusion out, thus can put shape diameter size different of molecular, polar degree different of molecular, boiling point different of molecular, saturated degree different of molecular separation from, that has "screening" molecular of role, Known as molecular sieves.Current molecular sieve in chemical, electronics, petrochemicals, natural gas is widely used in the industry.
