Coconut shell activated carbon purchase Zeolite molecular sieve is a kind of excellent adsorbent, which is widely used in the production of basic organic chemical industry and petrochemical industry, as well as in the treatment of harmful gases nox、co、co2，nh3，ccl4、 Purification of water vapor and gaseous hydrocarbon waste gas; As well as air purification and deodorization in biochemical industry, paint industry, underground places, leather factories and animal breeding places; Adsorption of flue gas odor, removal of mercury vapor, etc. The main material of honeycomb zeolite adsorbent is natural zeolite, Coconut shell activated carbon Beijing The zeolite manufacturer 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.
The zeolite wheel adsorption purification device is a gas purification device that can continuously perform adsorption and desorption operations. Coconut shell activated carbon purchase The two sides of the zeolite runner are divided into three areas by special sealing devices: adsorption area, desorption (regeneration) area and cooling area. The working process of the system is as follows: the zeolite runner rotates continuously at a low speed and circulates through the adsorption area, desorption (regeneration) area and cooling area; When the exhaust gas with low concentration and large air volume continuously passes through the adsorption area of the runner, VOCs in the exhaust gas are adsorbed by the zeolite of the runner, and the gas purified by adsorption is directly discharged; The organic solvent adsorbed by the wheel is sent to the desorption (regeneration) area along with the rotation of the wheel, and then continuously passes through the desorption area with small amount of hot air, purchase Beijing VOCs adsorbed on the runner are thermally desorbed in the desorption area to achieve regeneration, and VOCs waste gas is discharged with hot air; After the runner is transferred to the cooling area for cooling, it can be re adsorbed. With the continuous rotation of the runner, adsorption, desorption and cooling cycles are carried out to ensure the continuous and stable operation of waste gas treatment
Coconut shell activated carbon purchase The addition of retention aids in the wet end of paper making is an important way to improve filler retention, which has been widely used in industrial production. Some studies reported that clinoptilolite (particle size 0.5-2 μ m) was used as a microparticle retention aid to compare the retention effect with silica and bentonite microparticle retention aid systems. The retention effect of clinoptilolite retention aid is equivalent to that of the silica microparticle retention aid system with the same dosage, which is far better than that of the bentonite microparticle retention aid system. And the use of zeolite as paper filler eliminates the need for additional microparticle retention aids. It is also reported that the retention rate of TiO2 nanoparticles can be significantly improved by using zeolite molecular sieves as retention aids in the preparation of photocatalytic paper. Compared with starch and cationic polymer, zeolite molecular sieve microparticle retention aids have better effects on improving the retention and drainage properties of paper stock and improving the uniformity of paper. Coconut shell activated carbon purchase The use of zeolite particle retention aids can effectively avoid flocculation between fibers, and help to form fiber particle fiber flocculating particles. In addition, it can also support titanium dioxide nanoparticles.
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. Coconut shell activated carbon purchase 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. Coconut shell activated carbon production Since the adsorption does not undergo chemical changes, as long as the molecules concentrated on the surface are managed to drive away, the zeolite molecular sieve will have the adsorption capacity again. This process is the reverse process of adsorption, which is called the resolution or regeneration process.
Coconut shell activated carbon purchase (1) Due to the high whiteness of molecular sieves, the optical properties of paper can be improved. (2) It can improve the loose thickness and printability of the paper. (3) Molecular sieves can be used to prepare special papers such as gas filter paper, rust proof paper and photocatalysis paper due to their open structure. (4) It can be used for low weight newsprint and book paper, and can effectively avoid ink penetration. (5) Its ion exchange performance can avoid resin and filler deposition. （6） Coconut shell activated carbon Beijing It can be used for phenolic paper laminate to improve its corrosion resistance in humid environment. Phenolic paper laminates used as insulators in printed circuit boards and integrated circuits will be affected by electrolytic corrosion when exposed to high humidity. (7) It is mixed with titanium dioxide (TiO2) filler to produce high-quality white paper. Zeolite molecular sieve is a kind of excellent adsorbent, which is widely used in the production of basic organic chemical industry and petrochemical industry, as well as in the treatment of harmful gases nox、co、co2，nh3，ccl4、 Purification of water vapor and gaseous hydrocarbon waste gas; As well as air purification and deodorization in biochemical industry, paint industry, underground places, leather factories and animal breeding places; Adsorption of flue gas odor, removal of mercury vapor, etc.
