Product Description D001 Macroporous Strong Acid Cation Exchange Resin1. DescriptionD001 is a premium grade ,high cross-linked, macroporous strong acid cation exchange resin based on sulfonated polystyrene cross-linked with DVB, The higher DVB content together with its macroporous structure gives D001 increase resistance to thermal, chemical and physical shocks and enhances overall stability.D001 is intended for use in water softening, dealkalization, deionization and chemical processing applications. It is ideally suited for use in severe operating conditions, especially where standard grade resin are known to fail due to thermal,osmotic or oxidative attack.2.Typical Physical and Chemical Properties:ItemsSpecificationPolymer Matrix StructureStyrene Crosslinked with DVBPhysical Form and AppearanceMacroporous spherical beadsFunctional GroupsR-SO3ˉIonic Form ,as shippedNa+Total Capacity, Na+ form, wet, volumetric≥1.75 eq/l minMoisture Retention, Na+ form45-55% Particle Size Range0.45mm-1.25mm0.50mm-1.25mm0.63mm-1.25mmUniformity Coefficient (max.)1.6 or 1.4effective size≥0.5mmReversible SwellingNa+ → H+ (max.)5%Shipping Weight (approx.)770 -850g/lSpecific Gravity, moist Na+ Form1.25Temperature Limit120°C (250 °F) pH Range, Stability0 - 143.Suggested Operating Condition Maximum Temperature Na+ Form120°C (248oF) max.H+ Form100°C (212oF) max.Backwash Rate25 to 50% Bed ExpansionRegenerant ConcentrationHydrogen Cycle3% HCl or 2 to 3% H2SO4 Sodium Cycle6% to 8% NaCl or 3% NaOH Regenerant dosageHC1 or H2SO4HC1 or H2SO4 volume:resin volume =3:1NaClNaClvolume:resin volume =2:1NaOHNaOHvolume:resin volume =3:1Regenerant Flow Rate2 to 4 BV/hRegenerant contact TimeAt least 40 minutesService Flow Rate10-25m/h4.ApplicationsThey are mainly used Demineralization and Softening ,water treatment in high flow mixed bed system, catalysis of organic reactions.
