Detailed Description
201×4(711)Strong-Base Type I (Gel) Anion Exchange Resin 1. Description 201×4(711)is a high capacity, shock resistant, gelular,Type I ,strongly basic anion exchange resin supplied in the chloride or hydroxide form as moist, tough, uniform, spherical beads. 201×4(711)is intended for use in all type of deionization systems and chemical processing applications and is especially suited for use in regenerable mixed beds. it also shows good kinetics of exchange, enabling very low concentration levels of both strong and weak acid anions to be achieved at practical flowrates. 2.Typical Physical and Chemical Properties: ①Polymer Matrix Structure:Crosslinked Polystyrene Divinylbenzene ②Physical Form and Appearance:Spherical beads ③Functional Groups:R-N(CH3)3+ ④Ionic Form ,as shipped:CL- ⑤Total Capacity, CL form, wet, volumetric:≥1.3eq/l min ⑥Moisture Retention, CL form:48-58% ⑦Particle Size Range:0.3mm-1.2mm ⑧<0.3mm (max.):1% ⑨Uniformity Coefficient (max.) :1.6 ⑩effective size:0.4-0.7mm ⑾Reversible Swelling CL-→ OH –(max.): 20-30% ⑿Shipping Weight (approx.):660 -720g/l ⒀Specific Gravity, moist CL-Form:1.08 ⒁pH Range, Stability:0 - 14 3.Suggested Operating Condition ①Maximum Temperature: OH- Form 60 °C (140oF) max. CL- Form 80 °C (176oF) max ②Backwash Rate: 50 to 75% Bed Expansion ③Regenerant Concentration:2-4% NaOH ④Regenerant dosage: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 It is mainly used in pure water and high purity water manufacturing, sugar solution decolorization, wastewater treatment, extraction of biochemical products and radioelements etc
