Chelating Resin

Chelatting Resin

In general, the resin with high crosslinking degree has stronger selectivity to ions, and the selectivity of macroporous resin is less than that of gel type resin. The selectivity is larger in dilute solution and smaller in concentrated solution.

Macroporous resin is made by adding porogen in the polymerization reaction to form a framework of porous sponge structure, with a large number of micropores inside, and then introducing exchange groups. The size and quantity of the wetted resin can be controlled during manufacturing. The surface area of the channel can be increased to more than 1000m2 / g. This not only provides a good contact condition for ion exchange, shortens the distance of ion diffusion, but also increases many chain active centers. Through the van der Waals force between molecules, it can produce molecular adsorption, which can adsorb all kinds of non-ionic substances like activated carbon and expand its function. Some macroporous resins without exchange functional groups can also adsorb and separate a variety of substances, such as phenols in chemical plant wastewater.

When the salt content of raw water is high, electrodialysis, reverse osmosis and other processes can be used for pre desalination of raw water.

The wood adsorption chelating resin pool is composed of crystal form and CSP polymer material. It is especially suitable for wall panel to be used as the protection of air pipe, collecting pipe and monitoring panel in the system. Because of the adsorption balance of the surface water RF lens, the construction cost can be reduced, The effect of improving production efficiency, wood production system and pumping system can be designed more accurately in these aspects.

Moreover, the wood import provides a kind of pressure to the surface treatment of coating, which is not only conducive to regulating the adsorption cost and moisture resistance, but also a product of environmental protection in the process of urbanization, and the secondary utilization is more ideal.
