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. Honeycomb zeolite molecular sieve major 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. Honeycomb zeolite molecular sieve Direct selling 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.

High silica zeolite type molecular sieves, this kind of zeolite has a series, and ZSM-5 is widely used, with ZSM-8 and ZSM-11 having the same structure; The other group is ZSM-21, ZSM-35 and ZSM-38. ZSM-5 is often called high silica zeolite, with the Si/Al ratio up to 50 and ZSM-8 up to 100. This group of molecular sieves also shows hydrophobic characteristics. Honeycomb zeolite molecular sieve Direct selling Their structural units are similar to those of mordenite, consisting of pairs of five membered rings, with no cage like cavities and only channels. ZSM-5 has two sets of cross channels, one is straight through, the other is zigzag perpendicular to each other, both formed by ten yuan rings. The channel is oval and its window diameter is (0.55-0.60) nm. Honeycomb zeolite molecular sieve major Zeolites belonging to the high silicon group also have silicalite-1 of all silicon type, which has the same structure as ZSM-5, and silicalite-2 is the same as ZSM-11.

High honeycomb zeolite molecular sieve content The zeolite content of the zeolite runner is proportional to the adsorption concentration efficiency, Honeycomb zeolite molecular sieve major 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 Honeycomb zeolite molecular sieve 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.

Zeolite molecular sieves have the following potential applications. Honeycomb zeolite molecular sieve Direct selling (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. Honeycomb zeolite molecular sieve major (6) 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.

Honeycomb zeolite molecular sieve major Technical performance and characteristics: simple structure, convenient maintenance and long service life; High absorption and desorption efficiency, so that VOCss waste gas with high air volume and low concentration can be converted into low air volume and high concentration waste gas, reducing the cost of back-end final treatment equipment; The pressure drop generated by the adsorption of VOCs by the zeolite runner is extremely low, which can greatly reduce the power consumption; The overall system adopts pre assembly and modular design, which has a small space requirement and provides a continuous and unmanned control mode; The waste gas concentrated by the runner can meet the national emission standards; The adsorbent uses non combustible hydrophobic zeolite, which is safer to use; The disadvantage is that the one-time investment is high. The zeolite runner is essentially a concentrator, Honeycomb zeolite molecular sieve Direct selling The waste gas containing organic solvent after runner treatment is divided into two parts: clean air that can be discharged directly and regeneration air containing high concentration organic solvent. The clean air that can be directly discharged can enter the spray paint air conditioning ventilation system for recycling; The concentration of high concentration VOCs is about 10 times that of the VOCs before entering the system. The concentrated gas is then incinerated at high temperature through the TNV recovery thermal incineration system (or other equipment). The heat generated by incineration is respectively used to heat the drying room and the zeolite wheel desorption. The heat is fully used to achieve the effect of energy conservation and emission reduction.
