The strongly basic ion exchange resin is an anion exchange resin with quaternary ammonium groups incorporated into the styrene frame. Two types with differing alkalinity strengths are: Type I with a trimethyl ammonium group, and Type II with a dimethylethanol ammonium group.
The strongly basic resin is used to produce high purity demineralized water, making use of the capability to strongly adsorb anions.
Lanlang strongly basic ion exchange resins are based on crosslinked polystyrene matrix having quaternary ammonium groups (NR3+). Among the Lanlang product line, there are gel type, porous type, and highly porous-type. The standard shipping is Cl-form (in some cases OH- form is available).
Type I resins have trimethyl ammonium groups which impart higher basicity. In the co-current regeneration mode, the treated water will have the lowest silica leakage. Type I resins also have higher chemical stability and can be applied at higher temperature than type II or acrylic based resins.
