001×7MB styrene series strongly acidic cation exchange resin
详细说明
001×7MB is a sort of cation exchange resin that has sulfonic group (-SO3H) in the styrene-diethylene benzene copolymer with 7% cross-linked degree. It is used mainly to produce pure water and ultra pure water in the mixed bed system, with the characteristics such as excellent hydraulics trait and physical stability.
Executing standard: GB/T 13659-2008 DL/T 519-2014
