717强碱性阴离子交换树脂是在苯乙烯二乙烯苯交联共聚物基体上引入季铵基[-N(CH3)3OH]，使其成为凝胶型717阴离子交换树脂。其碱性相当于强碱，在酸性、中性甚至碱性介质中显示离子交换功能。具有机械强度好、耐热性能高等特点。
The 717 strong basic anion exchange resin introduces quaternary ammonium base [-N (CH3) 3OH] on the styrene two ethylene benzene cross-linked copolymer matrix, making it a gel type 717 anion exchange resin. Its alkalinity is equivalent to strong alkali, and it shows ion exchange function in acidic, neutral and even alkaline medium. It has good mechanical strength and high heat resistance.
是大孔结构的苯乙烯一二乙烯苯共聚体上带有叔胺基[-N(CH3)2]的离子交换树脂，其碱性较弱，能在酸性、近中性介质中有效地交换无机酸及硅酸根，并能吸附分子尺寸较大的杂质以及在非水溶液中使用，该树脂具有再生效率高、碱水耗低、交换容量大、抗有机物污染及抗氧化能力强、机械强度好等优点。
Ion exchange resin with tertiary amino group [-N(CH3)2] on macroporous styrene-divinylbenzene copolymer is weak in alkalinity. It can exchange inorganic acids and silicates effectively in acidic and near-neutral media. It can adsorb impurities with larger molecular size and be used in non-aqueous solutions. The resin has high regeneration efficiency. Low alkali water consumption, large exchange capacity, strong anti-organic pollution and anti-oxidation ability, good mechanical strength and so on.
