离子交换树脂贮存、运输应注意什么

What should be paid attention to in storage and transportation of ion exchange resin

（1）离子交换树脂内含有一定量的水份，在贮存和运输过程中应保持这部分水份。离子交换树脂在贮存中若出现脱水，使用前应先将其浸入浓度为10%左右的食盐溶液中，使其缓慢充分膨胀后，再用清水逐渐稀释。切忌将脱水的树脂直接浸入水中，以免树脂体积急剧膨胀而破碎。

(1) the ion exchange resin contains a certain amount of water, and this part of water should be maintained during storage and transportation. If there is dehydration in the storage of ion exchange resin, it should first immerse it in salt solution with a concentration of about 10% before expanding it, then slowly dilute it with water. Avoid the dehydrated resin directly in water so as to avoid the sharp expansion of the resin volume.

（2）离子交换树脂暂不使用时，应以下述离子型式贮存：阳离子交换树脂为钠（Na）型；阴离子交换树脂为氯（Cl）型；弱碱阴离子交换树脂为游离胺型。

(2) when ion exchange resin is not used, it should be stored in the following ionic types: cation exchange resin is sodium (Na) type, anion exchange resin is chlorine (Cl) type, weak base anion exchange resin is free amine type.

（3）离子交换树脂在贮存过程中应防止铁锈、油污、强氧化剂，有机物的污染，以免发生氧化降解、中毒等事故。

(3) ion exchange resin should prevent rust, oil pollution, strong oxidizing agent and organic matter pollution during storage, so as to avoid oxidative degradation and poisoning.

（4）离子交换树脂在贮存及运输过程中，应尽量保持5~40℃的温度环境，避免过冷或过热造成树脂被冻裂或加速微生物繁殖而影响产品质量，降低产品性能。

(4) ion exchange resin in the storage and transportation process, should try to keep the environment temperature 5~40 degrees Celsius, avoid hot or cold or frozen by resin accelerated microbial reproduction and affect the quality of products, reduce product performance.

（5）在冬季如没有保温装置，也可将树脂贮存在食盐水中，食盐水的浓度可根据气温而定，避免结冰。

(5) in winter, if there is no heat preservation device, the resin can be stored in the salt water. The concentration of the salt water can be determined according to the temperature, and the ice can be avoided.
