Ion exchange resin prices

Full name of ion exchange resins by the class name, skeleton (or genes) name, consisting of the base name. Pore ??Structure gel type and macroporous two, who said macroporous resin has physical pore structure, in front of the full name with the "big hole." Classification is acidic should be added "yang" in front of the name, is classified as alkaline, add before the name "Yin." Such as: styrene macroporous strong acid cation exchange resin. First, the ion exchange resin application areas: 1, Water 2, 3 food industry, the pharmaceutical industry 4, synthetic chemical and petrochemical industry 5, 6 environmental protection, hydrometallurgy and the other two, the ion exchange resin Note: 1, Ion exchange resin contains some water, not open storage, storage and transportation process should be kept moist in order to avoid dehydration dried, crushed resin, such as resin dehydrated during storage, should be (10%) with concentrated salt water soak, and then gradually diluted may not be directly into the water, in order to avoid a sharp expansion of the broken resin. 2, winter storage and use, should be kept at a temperature of 5-40 ℃ environment, avoiding hot or cold, affecting the quality, if there is no insulation in winter equipment, resin can be stored in salt water, salt water concentration can be according to the temperature be. 3, ion exchange resins for industrial products, often contain a small amount of low polymer and unreacted monomer, also contains iron, lead, copper and other inorganic impurities, when the resin in contact with water, acids, alkalis or other solution, said Substances will be transferred to the solution, affect water quality, so the new resin must be pretreated prior to use, generally with water so that the resin fully inflated, then, on which the inorganic impurities (mainly iron compounds) can be 4-5 % diluted hydrochloric acid to remove organic impurities available 2-4% dilute sodium hydroxide solution was removed, washed to near-neutral can be. As used in the pharmaceutical preparation, must use ethanol soaking. 4, the resin in use, to prevent contact with the metal (such as iron, copper, etc.) oil, organic molecular microbiology, strong oxidants, free ion exchange capacity reduced, or even loss of function, and therefore, the resin is required from time to time depending on the circumstances activation process, the activation method according to the pollution situation and conditions, are generally susceptible to contamination Hydrochloric acid cation resin Fe soaked in a softening, and then gradually diluted organic anion resin susceptible to contamination, can be 10% NaC1 + 2-5% NaOH soak or rinse the mixed solution, 1% of hydrogen peroxide solution soak a few minutes, if necessary, other may also be used alternately acid treatment, bleaching treatment, alcohol treatment and a variety of sterilization and the like. 5, the pre-new resin: Ion exchange resins for industrial products, often contain a small amount of oligomers and unreacted monomer, also contains iron, lead, copper and other inorganic impurities. When the resin in contact with water, acids, alkalis or other solution, these substances will be transferred to the solution, and affect water quality. Therefore, the new resin must be pretreated prior to use. Generally the resin swell with water, then, on which the inorganic impurities (mainly iron compounds) removing Available 4-5% diluted hydrochloric acid, organic impurities can be used 2-4% dilute sodium hydroxide solution to a near neutral wash that is removed can. Third, the ion exchange resin preservation methods: ion exchange resins can not open storage, storage at a temperature of 0-40 ℃, when stored at temperatures slightly below 0 ℃, should be added to clarify the packaging bag saturated brine, soak resin . In addition, when stored at high temperature, not only the resin easy to dehydration, but also accelerate the degradation of anion resin. Once the resin water loss, not increase the use of direct water available to clarify the saturated salt water soak, and then gradually diluted with water, wash away the salt, should be to keep it moist during storage.
