  • Preparation of ultrapure water for electronic industry
    • 2021-06-08

    In the electronic industry, from the cleaning of various electronic components to the preparation of a series of process solutions, high-quality pure water is needed, especially in the production of semiconductor devices and large-scale integrated circuits. Almost every process needs to be cleaned with ultrapure water. Ultra pure water plays an increasingly important role in the electronic industr...

  • Desalination by ion exchange resins
    • 2021-07-16

    In industries such as thermal power plants, petroleum and chemical industries, microelectronics, nuclear, food and pharmaceutical industries, all require water close to the quality of distilled water. With the rapid development of industrial technology, not only the amount of water is increasing rapidly, but also the requirements for water quality are constantly increasing. So far, the ion exchang...

  • Principle of equipment setting in chemical demineralization system
    • 2021-10-11

    (1) The cation exchanger is located in front of the anion exchanger. The reasons are as follows: a. the exchange capacity of strong base anion exchange resin is low, and the ion exchange reaction efficiency of strong base anion resin in acidic water (H-type cation resin exchange water) is high, and the working exchange capacity can be fully utilized. b. After the raw water is exchanged by H-type c...

  • Synthesis of styrene ion exchange resin(3)
    • 2022-06-21

    In addition to conventional ion exchange resins, micron fine-grained ion exchange resins are also developing rapidly. This kind of resin is mainly used for chromatographic separation. Therefore, a sufficiently small particle size (100~400 mesh) and a relatively narrow particle size distribution are key technical indicators. Suspension polymerization can prepare spheres with diameters ranging from ...

  • Preparation of Macroporous Crosslinked Copolymer Spheres (Macroporous Ion Exchange Resin) (III)
    • 2022-10-14

    When the macroporous ion exchange resins is used as a porogen in a bad solvent, the properties, dosage and crosslinking degree of the porogen have significant effects on the pore structure of the copolymer. With the increase of the amount of divinylbenzene and pore forming agent, the phase separation appeared earlier and the gel point also appeared earlier. The separated macromolecular chains are ...

  • Basic types of ion exchange resins
    • 2022-11-10

    (1) Strong acid cation resin This kind of resin contains a large number of strong acidic groups, such as sulfo SO3H, which is easy to dissociate H+in solution, so it is strongly acidic. After the resin is dissociated, the negative group contained in the body, such as SO3 -, can adsorb other cations in the bound solution. These two reactions make the H+in the resin exchange with the cation in the s...

  • Filling and Pretreatment of Anion and Cation Resins in Mixed Bed
    • 2022-12-05

    The specific operations are as follows: Clean the bed and put water 1-2 meters deep (ensure that the water surface is higher than the resin layer): 1. The design height shall be filled with resin (the final height of resin shall be subject to re ecology). 2. After installing the cation exchange resin, backwash to make the resin surface smooth, and then install the anion exchange resin; Two steps h...
