Detailed Description
D213 macroporous strongly basic acrylic series anion exchange resin 1. Description D213 is a sort of anion exchange resin which has quaternary ammonium group [-N(CH3)3OH] in the cross linking crylic acid framework with macroporous structure. It is used mainly as the organic substance removing matter as well as absorb resin in decolorization . 2.Typical Physical and Chemical Properties: ①Polymer Matrix Structure: Acrylic Crosslinked with DVB ②Physical Form and Appearance:Spherical beads ③Functional Groups:R-N(CH3)3+ ④Ionic Form ,as shipped:CL- ⑤Total Capacity, Na+ form, wet, volumetric:≥0.85eq/l min ⑥Moisture Retention, CL-form:65-75% ⑦Particle Size Range:0.40mm-1.25mm ⑧<0.4mm (max.):1% ⑨Uniformity Coefficient (max.):1.6 ⑩effective size:0.5-0.7mm ⑾Shipping Weight (approx.):650 -720g/l ⑿Specific Gravity, moist Na+ Form:1.08 ⒀pH Range, Stability:0 - 14 3.Suggested Operating Condition ①Maximum Temperature:CL- Form 75oC (155oF) max. ②Bed depth, min.: 600 mm ③Backwash Rate: 50 to 75% Bed Expansion ④Regenerant Concentration:2-4% NaOH ⑤Regenerant dosage:NaOH volume:resin volume =3:1 ⑥Regenerant Flow Rate:2 to 8 BV/h ⑦Regenerant contact Time:At least 60 minutes ⑧Service Flow Rate:10-25m/h 4.Applications For Efficient Demineralization Including Silica Removal,Preparation of pure water from high organic water source. The resin has high operating exchange property, and strong anti-pollution characteristics.
