产品详细

SQD-729是-种大孔苯乙烯系强碱性阴离子交换树脂，专用于乙二醇生产中水的循环回用处理。可有效去除水中的各种阴离子，与SQD-61 / SQD-92 / 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-729 is a macroporous polystyrene-based strong anion exchange resin. It is specially designed for the recycling water treatment in the ethylene glycol production. Combined with one or all of SQD-61 / SQD-92 / SQD-749, the UV value of the treated water could be largely increased, so that the quality of ethylene glycol 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-729树脂再生时，用2-3倍树脂体积的3-4%的氢氧化钠，45-60 分钟从上到下通完。然后用去离子水冲洗至出水中性即可。

SQD-729 resin is usually used in single column. When the conductivity or the UN value of the water, after the combined treatment, is over the required limit, the resins are exhausted. The exhausted SQD-729 is regenerated by passing 2-3BV of 3-4% NaCl through the resin in 45-60 min from top to bottom. Then wash with DI water until pH of the effluent close to neutral. Then the resin is ready for next run.
