Fine chemical industry is an important new field of the modern chemical industry, involving the field is very wide, along with economic development, the development of fine chemical industry design field also constantly explore, ultrapure water equipment is fine chemical industry one of the indispensable equipment. This equipment can be applied to chemical materials used in the production and processing process of solvent and the cleaning process, and other solid state electronics, thick film and thin film circuit, etc. Production preparation of ion exchange resin, to remove the water electrolyte almost entirely, and simple regeneration, regeneration rate is high, further improve the filtering effect, ensure the purity of ultrapure water.
