DESCRIPTION |
Strong Acid Cation Ion Exchange Resin for Softening and Demineralization is a versatile ion exchange material with sulfonic acid functional groups attached to a polystyrene-divinylbenzene matrix. This resin effectively removes cations from water through two primary mechanisms: sodium cycle operation for softening (removing Ca²⁺ and Mg²⁺) and hydrogen cycle operation for demineralization (removing all cations).
Industrial Water Softening: Removes hardness ions (calcium and magnesium) from boiler feedwater, process water, and cooling water to prevent scale formation.
Water Demineralization: Works in conjunction with anion exchange resins in deionization systems to produce high-purity water.
Dealkalization: Partial demineralization to reduce alkalinity and associated hardness.
Metal Recovery: Recovers valuable metals from process streams in hydrometallurgical applications.
Chemical Processing: Serves as a catalyst in various chemical reactions including esterification and hydrolysis.
