Ion-exchange resin matrix, the main raw material for producing styrene and acrylic acid (ester) two categories, which are produced with the crosslinking agent divinylbenzene polymerization to form a network skeleton structure has long molecular backbone and cross-linking of cross-chain polymer. Styrene resin is first used an acrylic resin is used a little bit more later. Crosslinking of the resin, the resin matrix that is the percentage of polymerization of divinylbenzene with, have a great effect on the properties of the resin. Typically, the high degree of crosslinking polymerization of the resin was relatively close, fastness and durable, high density, low internal voids, strong selectivity for ion; and a low degree of crosslinking of the resin pores larger, stronger decolorization The reaction is faster, but the expansion of the work of a large, mechanical strength lower, more brittle and fragile. The degree of crosslinking of ion exchange resins for industrial applications is generally not less than 4%; degree of crosslinking resins used for bleaching is generally no higher than 8%; pure resin for the adsorption of inorganic ions, which may be a high degree of crosslinking. Resin filter weak acid cation exchange resin: This product is an acrylic copolymer with macroporous structure with a carboxylic acid ion cross (-COOH) on exchange-linked polymer matrix resin, the resin has excellent dynamic characteristics, and has high regeneration efficiency, low acid consumption, exchange capacity and other characteristics. The main purpose of the water treatment can be very obvious to remove alkalinity and hardness, especially the removal of bicarbonate, carbonate and other alkaline salts, mainly for the high salt content of the water; a large amount of water to soften off alkali treatment; waste acid and waste alkali; electroplating copper, nickel and wastewater treatment; and pharmaceutical, food and sugar, can also be used for waste recycling and disposal, separation and purification of biological drugs. Weakly basic anion exchange resin: This product is an ion with a styrene or two benzene copolymer with macroporous structure tertiary amine group [-N (CH3) 2] The exchange resin weak alkaline, can be acidic nearly neutral medium effective exchange inorganic acid and silicate, and can absorb impurities larger molecular size and the use of non-aqueous solution, the resin has a high regeneration efficiency, low alkali consumption, large switching capacity, resistance to organic pollution and antioxidant capacity, good mechanical strength and so on. Preparation for the main water and high water for the female re-bed system, a high salt content of the water is particularly appropriate, and to protect the strong base anion exchange resin from organic pollution and sugar bleaching wastewater containing chromium and recycling. Ion exchange resin filter is a polymer with appropriate functional groups. In general, a conventional sodium ion exchange resin with a large amount of sodium ions. When the high water content of calcium and magnesium ions, the ion exchange resins can release sodium ions, functional groups and the calcium and magnesium ions, calcium and magnesium ions so that the water content is reduced, water hardness decreases. Hard water becomes soft, which is the working process of water softening equipment. 1, the ion exchange resin prior to loading thoroughly cleaned and checked. Ensure that all accepted resin containers before loading the resin is cleaned and washed with deionized water washout. 2, the resin is charged with deionized water column regeneration, the column was added in the regeneration of deionized water to drain from the lower impact resin. It recommends the introduction of water will force the resin mixed water into a container. It can also "fall" into the containers, but should always be kept in the liquid resin layer. Do not filled with resin using a mechanical pump. The maximum rate of not more than 1m / s, water and resin mixing ratio> 2: 1. 3, convinced deionized water level above the resin bed has been loaded at least 0.5m above the. The resin was then soaked in deionized water for at least 2 hours. Soak longer, the resin harmless. (For weakly basic and the basic resin (Lewatit MP 62, MonoPlus MP 64, etc.) must be soaked overnight to make it through, to prevent loss of resin backwash. 4, after the soaking, carefully and thoroughly backwash resin about 30min. Remove All of the resin fine particles and the filling process into the foreign matter. There may be some fine resin may or may not. backwash should not have windows at the outlet, which would prevent the removal of the resin fine particles, all of fine particles must Backwash out of the container. Be careful not to good resin also backwash out of the container. backwash effluent start when the cation resin may be brown, do not worry, this is the common characteristic of sulfonic acid resin, continue backwash until Anti-free lotion to clarify the fine particles. Recommended backwash step, 50% of resin per backwash, backwash rate based on technical information provided by the resin. anion resin and cation resin is best to use two different backwash tower to prevent cross-contamination. 5, all the process, the need to use deionized water, if there is no de-ionized water, first with the raw water backwash cation resin, and a cationic resin softened raw water backwash and loaded anion resin. 6, para. Before first use the resin, times the amount of regenerant used, recycled resin note: only need to increase the amount of regeneration agent, do not increase the concentration of regenerant 7, since the resin expands during regeneration, it is recommended that the first 90% of the filling. resin, regenerated, rinsed, and then padding the remaining swelling degree of a resin according to the resin.
