Sodium resin material:
The sodium resin material was filled into water softer. The water softer can use Na+ change the metel ion , to make the water soften. Mixed bed (Na ion resin) let the anion and cation exchange resin to filling in the same ion exchanger according to a certain proportion, due to H ion and OH ion was generated low ionization degree water molecules immediatel after mixing ion exchanged and go into the water. So it is important part of water treatment.
