Herstellung von schwach sauren Kationaustauschharzen

摘要

An improved process for cleaning weak acid cation exchange resin intermediates resulting in finished weak acid resins providing enhanced performance of mixed-bed water-treatment systems is disclosed. The cleaning process involves selected steam treatment during the manufacturing process of the resins and is applicable to weak acid cation exchange resins in general that are used as components in potable water treatment systems, such as cartridge-water-pitcher systems.
