D301大孔弱碱性阴离子交换树脂

D301是一个非常耐用的大孔弱碱性阴离子交换其特征在于附着到苯乙烯二乙烯基苯共聚物基质叔胺基团的树脂。它具有独特的生理结构，这使得它卓越的动力学和渗透压冲击比凝胶型弱碱性阴离子交换更大的阻力。

D301收益率烧碱再生极高的经营能力，并具有较低的清洗要求。它具有比凝胶类阴离子交换剂有机质高的电阻。

D301被作为湿润球形珠粒以游离碱形式的，准备使用。 D301去除游离矿酸离子像氯化物，硫酸盐，硝酸盐等，但不会删除弱酸性离子，如二氧化硅和二氧化碳。在去矿质系统，D301可置于强碱阴离子交换前述。该系统提供了一个更经济的再生成本，D301在工作相比非常高的再生效率强碱器。额外的节省可以通过重新生成弱碱强碱器串联来实现。设计必须，但要小心防止二氧化硅沉淀在弱碱交换。 D301是否放置在前述的强碱阴离子交换还用来保护它免受有机污染。

用途： D301是适合于脱矿质水与顺流或现代逆流系统操作工业蒸汽产生。它能够从进水除去高分子量的有机材料，从而保护一个以下强碱树脂结垢。将有机物容易洗脱，再生树脂显示出良好的漂洗特性，并在相对高的TDS水域非常可接受的操作的能力。

虽然还有其他一些专门定制的大孔的D301系列中间基树脂，D301本身可能是最普遍有用的。适当分级版本，D301MB建议使用与201 II型联合或201x4层状床离子交换系统。

D301 Macroporous Weak Base Anion Exchange Resin

D301 is an extremely durable macroporous weak base anion exchange resin characterized by tertiary amine groups attached to a styrene divinylbenzene copolymer matrix. It has a unique physical structure which gives it superior kinetics and greater resistance to osmotic shock than gel type weak base anion exchangers.

D301 yields exceptionally high operating capacity on caustic soda regeneration and has low rinse requirements. It has a higher resistance to organic matter than gel type anion exchangers.

D301 is supplied as moist spherical beads in free base form, ready to use. D301 removes free mineral acid ions like chloride, sulphate, nitrate etc. but will not remove weak acid ions like silica and carbon dioxide. In a demineralization system, D301 can be placed preceding a strong base anion exchanger. This system offers a more economical regeneration cost, as D301 operates at a very high regeneration efficiency in comparison to strong base exchangers. Additional savings can be achieved by regenerating the weak base and strong base exchangers in series. The design must, however take care to prevent silica precipitation on the weak base exchanger. D301 placed preceding a strong base anion exchanger also serves to protect it from organic fouling.

APPLICATIONS: D301 is suitable for demineralization of water for industrial steam generation operated with co-current or modern counter-current systems. It is able to remove high molecular weight organic materials from the influent water, thus protecting a following strong base resin from fouling. The organics are readily eluted, and the regenerated resin shows good rinse behavior, and a very acceptable operating capacity on relatively high-TDS waters.

While there are several other specially-tailored macroporous intermediate-base resins in the D301 series, D301 itself is probably the most generally useful. A suitably-graded version, D301MB is recommended for use in conjunction with 201 II type or 201x4 in layered-bed anion exchange systems.
