Detailed Description
D001 Macroporous Strong Acid Cation Exchange Resin 1. Description D001 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: ①Polymer Matrix Structure:Styrene Crosslinked with DVB ②Physical Form and Appearance:Macroporous spherical beads ③Functional Groups:R-SO3ˉ ④Ionic Form ,as shipped:Na+ ⑤Total Capacity, Na+ form, wet, volumetric:≥1.75 eq/l min ⑥Moisture Retention, Na+ form:45-55% ⑦Particle Size Range:0.45mm-1.25mm 0.50mm-1.25mm 0.63mm-1.25mm ⑧Uniformity Coefficient (max.) :1.6 or 1.4 ⑨effective size:≥0.5mm ⑩Reversible Swelling:Na+ → H+ (max.) 5% ⑾Shipping Weight (approx.):770 -850g/l ⑿Specific Gravity, moist Na+ Form:1.25 ⒀Temperature Limit:120°C (250 °F) ⒁pH Range, Stability:0 - 14 3.Suggested Operating Condition ①Maximum Temperature:Na+ Form 120°C (248oF) max. H+ Form 100°C (212oF) max. ②Backwash Rate: 25 to 50% Bed Expansion ③Regenerant Concentration:Hydrogen Cycle 3% HCl or 2 to 3% H2SO4 Sodium Cycle 6% to 8% NaCl or 3% NaOH ④Regenerant dosage:HC1 or H2SO4 HC1 or H2SO4 volume:resin volume =3:1 NaCl volume:resin volume =2:1 NaOH volume:resin volume =3:1 ⑤Regenerant Flow Rate:2 to 4 BV/h ⑥Regenerant contact Time:At least 40 minutes ⑦Service Flow Rate:10-25m/h 4.Applications They are mainly used Demineralization and Softening ,water treatment in high flow mixed bed system, catalysis of organic reactions.
