001x7 cationic resin softening resins Purolite resin imported resin wholesale price

(1) strong acid cation resin containing a large amount of such resins strongly acidic groups such as sulfonic acid group -SO3H, readily dissociate in solution, H +, and therefore is strongly acidic. After the resin dissociation, the body contains negatively charged groups, such as SO3-, can adsorb other cationic binding solution. Both reacting the resin H + exchange cations in solution. Strong Acid dissociation strong, can produce dissociation and ion exchange acidic or alkaline solution. Resin in use for some time, to be regenerated, which uses chemicals to make ion exchange reaction in the opposite direction, so that the resin functional groups regain its original state and ready to use again. As described above with a strong acid cation resin is regenerated, when the adsorbed cation resin discharged, then combined with H + and to restore the original composition. (2) weak acid cation resin such resins containing weakly acidic groups, such as carboxyl -COOH, can dissociate the H + in water and acidic. The resin was dissociated remaining negatively charged group such as R-COO- (R is a hydrocarbon group) can be combined with the adsorption of other cations in solution, resulting in a cation-exchange effect. Such acidic resins i.e. dissociation weak, it is difficult to exchange and ion dissociation at low pH, only (e.g. pH5 ~ 14) acts in an alkaline, neutral or slightly acidic solution. Such resins are also used acid regeneration (easier than the strongly acidic resin regeneration). (3) strong base anion resins such resin containing strongly basic groups such as quaternary amine (also known as four amino) -NR3OH (R is a hydrocarbon group), to dissociation of OH- in the water and showed strongly basic. This resin can absorb the positively charged groups bind anions in solution, resulting in an anion exchange effect. This resin dissociation strong, can work at different pH. It is regenerated with a strong base (e.g. NaOH). (4) Weak base anion resins such resin containing weakly basic groups, such as primary amine groups (also known as an amine) -NH2, secondary amine (secondary amino groups) -NHR, or a tertiary amine group ( three amino) -NR2, they can dissociate in water and weakly alkaline OH-. This resin can absorb the positively charged groups bind anions in solution, resulting in an anion exchange effect. This resin solution in most cases is the whole other acid molecule adsorption. It can only work under neutral or acidic conditions (eg pH1 ~ 9). It can be used Na2CO3, NH4OH reproduction. (5) transition ion resin of the above are the four basic types of resins. In actual use, often these resins into other ion type run to suit every need. For example, often the strong acid cation resin and NaCl effect, into a sodium-type resin used again. Work release sodium resin solution Na + and Ca2 +, Mg2 + and other cation exchange adsorption, removal of these ions. No release reaction H +, can be avoided and the resulting solution pH decreased side effects (such as invertase and equipment corrosion etc.). This resin after sodium operational use, available brine regeneration (without acid). Another example is the anion resin can be converted to a chlorine-type re-use, release Cl- work and other anion exchange adsorption, its regeneration only with saline solution. Chlorine type resins can also be converted to bicarbonate type (HCO3-) running. Strongly acidic resin and a strongly basic resin into sodium and chlorine type after it is no longer strongly acidic and strongly basic, but they still have other typical properties of these resins, such as dissociation of strong and broad working pH range and so on. 001 × 7 strong acidic styrene cation exchange resin technical standards: GB / T13659-92, DL519-93, SH 2605.01-1997 The product is a sulfonic acid group (-SO3H on styrene or two benzene copolymer matrix ) ion exchange resin, which has a high switching capacity, switching speed, good mechanical strength and other characteristics.
