产品详细

SQD-61是一种苯乙烯系强酸性阳离子交换树脂，专用于乙二醇生产中水的循环回用处理，可有效去除水中的阳离子，与sQD-92 / SQD-729 / SQD-749中的一种或多种组合， 可以大幅提高水的UV值(紫外透光率)，从而提高乙二醇的产品品质。

SQD-61 is a macroporous polystyrene -based strong acidic cation exchange resin. It is specially designed for the recycling water treatment in the ethylene glycol (MEG) production. Combined with one or all of SQD-92 / SQD-729 / SQD-749, the UV value of the treated water could be largely increased, so that the the quality of MEG obtained could also be largely increased.

▲树脂再生方法(Regeneration Method)
在经过多种树脂综合处理过的水的电导率或UV值超标时，树脂需要再生。对SQD-61树脂再生时，用2-3倍树脂体积的4%的盐酸，45-60 分钟从上到下通完。然后用去离子水冲洗至中性即可。

SQD-61 resin is usually used in single column. When the conductivity or the UV value of the water, after the combined treatment, is over the required limit, the resins are exhausted. The exhausted SQD-61 is regenerated by passing 2-3BV of 4% HCI through the resin in 45-60 min fromtop to bottom. Then wash with DI water to pH neutral. Then the resin is ready for next run.
