Activated carbon filter screen Shandong There are cavities and channels in the crystal structure of zeolite with large adsorption capacity, whose volume accounts for more than 50% of the total volume of zeolite crystals. Moreover, the micropores of zeolite are evenly distributed, and the pore size is small, which is equivalent to the molecular size of general substances. The internal surface area of zeolite crystals can reach more than 1000 square meters. Therefore, the adsorption capacity of zeolite is particularly large. The holes and channels inside the highly selective zeolite crystal are uniform and fixed in size, and the diameter of the holes is generally 6~15A. Activated carbon filter screen Direct selling 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.

High honeycomb zeolite molecular sieve content The zeolite content of the zeolite runner is proportional to the adsorption concentration efficiency, Activated carbon filter screen purchase Therefore, when choosing to purchase zeolite runner, the matching zeolite content should be selected in combination with the emission concentration of enterprise exhaust gas pollutants. 2、 With good hydrophobicity, choose to purchase zeolite with large specific surface area. 2) Select inspection equipment to test the hydrophobicity of equipment Activated carbon filter screen Direct selling 。 When the air humidity is greater than 60%, calibrate the equipment. If the equipment is blocked and the machine works abnormally, it indicates that the equipment has poor hydrophobicity, and you should carefully consider whether to purchase the equipment.
Activated carbon filter screen purchase 1. From the composition of both, carbon molecular sieve is an excellent non-polar carbon material, while zeolite molecular sieve is a hydrate of crystalline aluminosilicate metal salt. The two are completely different in the periodic table of chemical elements! 2. With different pore sizes, the pore composition of zeolite molecular sieves is obviously registered, which can be generally divided into macropores, mesopores and micropores, and there are interconnections between the pores, while carbon molecular sieves are generally micropores! 3. The adsorption principle is different. Zeolite molecular sieves absorb molecules of certain size and repel molecules of larger substances. Activated carbon filter screen Shandong Carbon molecular sieve contains a large number of micropores, which can effectively separate the components of gas mixture. 4. The uses are also different. Carbon molecular sieves are widely used in coal fields, petroleum, chemicals, metal heat treatment, electronic manufacturing, food preservation and other industries, while zeolite molecular sieves can be used in addition to petroleum, chemicals, natural gas, electronic production, industrial gas separation, pharmaceutical industry, refrigeration industry, and hollow glass manufacturing.
Activated carbon filter screen Shandong Since the adsorption does not change chemically, Activated carbon filter screen purchase As long as we try to drive away the molecules concentrated on the surface, zeolite molecular sieves will have adsorption capacity again. This process is the reverse process of adsorption, which is called the process of desorption or regeneration. Honeycomb zeolite molecular sieve is a kind of aluminosilicate material containing alkali metal or alkaline earth metal oxide with open framework and regular pore cage structure. It has been widely used since it was discovered by Swedish scientists in 1956, and then it has been widely used in petrochemical industry, environmental protection, bioengineering and other fields due to its special physical characteristics. And with the gradual expansion of the demand for zeolite molecular sieves, researchers began to expand a variety of synthetic methods of zeolite molecular sieves to meet the needs of various fields. Zeolite molecular sieve has super strong adsorption performance, which is due to a "surface force" generated by molecular gravity on the solid surface. When the fluid flows, some molecules in the fluid collide with the adsorbent surface due to irregular movement, resulting in molecular concentration on the surface, reducing the number of such molecules in the fluid to separation Purposes of clearing
