 Shenzhen professional honeycomb zeolite molecular sieve manufacturer

The holes and channels inside the zeolite crystal are uniform and fixed in size, and the diameter of the holes is generally 6~15A. Honeycomb zeolite molecular sieve Shenzhen Only molecules with smaller diameter can enter the cavity through the zeolite channel and be adsorbed, while large molecules cannot enter the cavity and be adsorbed. Zeolite is also called molecular sieve because of its selective adsorption performance. However, silica gel, activated carbon and other adsorbents have no selective adsorption and screening performance due to their non uniformly fixed pore sizes and large changes. Shunyi zeolite filter material price. Because the silicon (aluminum) oxygen tetrahedron of natural zeolite crystal has many holes and channels, which occupy cations and water molecules. When some other goods are completely dehydrated after baking, the crystal skeleton is not damaged, but forms large holes on the inner surface, which can absorb and store a large number of molecules, so it has the characteristics of large adsorption capacity and high selectivity. Honeycomb zeolite molecular sieve major In different zeolite minerals, the proportion of silicon and aluminum is different, and the different proportion will cause some characteristics of zeolite changes, such as ion exchange and acid resistance.

Shenzhen Honeycomb zeolite molecular sieve Zeolite is a porous aluminosilicate crystal (a1uminsi1ict) with a water bearing frame structure, which exists naturally in nature and is also artificially synthesized. The ideal chemical formula of zeolite can be expressed as Mx/yA1XSiyO2 (x y) P? H2O, Where, M is alkali metal (such as Na, K, Li) and alkaline earth metal (such as Ca, Mg, Ba, Sr). The chemical composition of zeolite is generally considered to be composed of A12O3, SiO2, H2O and metal cations, of which A12O3 and SiO2 account for about 80% of the total zeolite minerals. In different zeolite minerals, the proportion of silicon and aluminum is different, Honeycomb zeolite molecular sieve manufactor And the different proportion of zeolite will cause some changes in zeolite characteristics, such as ion exchange and acid resistance. Because the silicon (aluminum) oxygen tetrahedron of natural zeolite crystal has many holes and channels, which occupy cations and water molecules. When some other goods are completely dehydrated after baking, the crystal skeleton is not damaged, but forms large holes on the inner surface, which can absorb and store a large number of molecules, so it has the characteristics of large adsorption capacity and high selectivity.

Honeycomb zeolite molecular sieve Shenzhen Because the aluminum oxide tetrahedron of zeolite has a negative charge, and the skeleton hole contains cations, a strong electric field is formed around the cations. Therefore, the adsorption force of zeolite not only has a strong dispersion force, but also has a large electrostatic force. It is precisely because of this electrostatic relationship that zeolites have preferential selective adsorption on polar, unsaturated and polarizable molecules. It can strongly adsorb molecules containing polar groups such as hydroxyl ion, ammonium ion and other polarizable groups, especially water, which can form hydrogen bonds with aluminum silicon skeleton, so zeolite has strong water absorption. It can still adsorb even under low relative humidity and concentration, and its water absorption is higher than that of silica gel and activated alumina. The main material of honeycomb zeolite adsorbent is natural zeolite. The manufacturer of zeolite is composed of silica Inorganic microporous material composed of al_2o_3 and alkaline metal or alkaline earth metal, with inner pore volume accounting for 40-50% of the total volume and specific surface area of 100-500 m2/g, is characterized by high temperature resistance, non flammability, good thermal stability and hydrothermal stability. It is an efficient molecular sieve carrier with good adsorption performance, no secondary pollution, and can be regenerated at high temperature. Compared with honeycomb activated carbon, its performance is about 25% of its efficiency, However, it is widely used in the fields of adsorption, separation, catalysis and environment due to its high temperature resistance and difficult ignition. It is more suitable for the treatment of organic waste gas with large air volume and low concentration.

Honeycomb zeolite molecular sieve major The highly effective selective adsorption is due to the fact that the alumina tetrahedron of zeolite has a negative charge, while the skeleton hole contains cations, which forms a strong electric field around the cations. Therefore, the adsorption force of zeolite not only has a strong dispersion force, but also has a large electrostatic force. It is precisely because of this electrostatic relationship that zeolites have preferential selective adsorption on polar, unsaturated and polarizable molecules. It can strongly adsorb molecules containing polar groups such as hydroxyl ion, ammonium ion and other polarizable groups, especially water, which can form hydrogen bonds with aluminum silicon skeleton, so zeolite has strong water absorption. It can still adsorb even under low relative humidity and concentration, and its water absorption is higher than that of silica gel and activated alumina. The adsorption capacity of zeolite for organic pollutants mainly depends on the polar size and molecular diameter of organic molecules. Small molecules are easier to be adsorbed than large molecules, while polar molecules are easier to be adsorbed than non-polar ones. Different substances (such as organic molecules, metal ions and water molecules) exist in water, Honeycomb zeolite molecular sieve manufactor Their polarity and molecular size are different, and competition will occur during adsorption.

Honeycomb zeolite molecular sieve is an efficient molecular sieve carrier with good adsorption performance, no secondary pollution and high temperature regeneration. It is widely used in the fields of adsorption, separation, catalysis and environment, Honeycomb zeolite molecular sieve major It is more suitable for the treatment of organic waste gas with large air volume and low concentration. It is widely used in the production of basic organic chemical industry and petrochemical industry, as well as in the treatment of harmful gases, SO2 NOx、CO、CO2,NH3,CCl4、 Purification of water vapor and gaseous hydrocarbon waste gas. Strong adsorption selectivity: molecular sieve materials with different properties and pore sizes are configured for the product according to the different components of organic waste gas, so as to achieve targeted and selective treatment of organic waste gas, meet the design requirements and meet the emission standards. 2. Strong adsorption capacity: even if the gas composition concentration is very low at the mg level, it still has the adsorption capacity. The efficiency is 50% higher than that of similar activated carbon. 3. Wide adaptability of adsorption temperature: at a higher temperature, it still has a large adsorption capacity, while other adsorbents are greatly affected by temperature, so under the same temperature, the adsorption capacity of molecular sieve is large. 4. Good regeneration temperature resistance: the concentration ratio of pollutants after adsorption and concentration by molecular sieve can reach 15 to 20 times, and the concentrated waste gas can be condensed and recovered or burned at high temperature as required 5. High strength: Honeycomb zeolite molecular sieve manufactor Products coming to the company use special framework materials to make the positive pressure strength of honeycomb zeolite reach more than 3Mpa, which can reduce damage during transportation and installation.
