Activated Carbon major 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. Activated Carbon major 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. Activated Carbon 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. Activated Carbon 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.

Zeolite molecular sieves have the following potential applications. Activated Carbon 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. Activated Carbon 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.

Molecular sieve is a crystalline silicate or aluminosilicate, which is a pore and cavity system with molecular size (usually 0.3nm to 2.0nm) formed by connecting silicon oxygen tetrahedron or aluminum oxide tetrahedron through oxygen bridge bond, Activated Carbon Fuzhou Therefore, it has the characteristics of screening molecules. However, with the deepening of molecular sieve synthesis and application research, researchers have found phosphoaluminate molecular sieves, and the skeleton elements (silicon or aluminum or phosphorus) of molecular sieves can also be replaced by B, Ga, Fe, Cr, Ge, Ti, V, Mn, Co, Zn, Be and Cu, and the size of its pores and cavities can also reach more than 2 nm, Activated Carbon major Therefore, molecular sieves can be divided into silicon aluminum molecular sieves, phosphorus aluminum molecular sieves and skeleton heteroatom molecular sieves according to the composition of skeleton elements;
