1. In long-term storage of ion-exchange resins, or long-term storage in decommissioned equipment, strong resins should be converted to salt types, and corresponding resins of weak type to hydrogen or free amine types can also be converted to salt types To keep the resin performance stable. Soak in clean water. If the decommissioned equipment needs to drain water, it should be sealed to prevent resin moisture from being lost.
2. The ion exchange resin contains a certain amount of equilibrium moisture. It should be kept moist during storage and transportation to prevent dehydration. The resin should be stored indoors or covered, and the ambient temperature should be 5 ~ 40 ℃. The bags of resin should be kept away from direct sunlight and away from heating devices such as boilers and heaters to avoid dehydration.
If it is found that the resin has been dehydrated, do not put it directly in water, otherwise the dry resin will swell sharply and break when contacted with water. According to the degree of dehydration, slowly add about 10% salt water to the resin, and gradually dilute with clean water after soaking for several hours.
3. When the ambient temperature is 0 ° C or below, in order to prevent the resin from cracking due to internal water freezing, heat preservation measures should be taken, or the resin should be stored in salt water of different concentrations according to the temperature conditions to prevent freezing. If the resin is found to have been frozen, it should be allowed to thaw slowly and naturally, and it should not be applied to the resin with mechanical force.
The relationship between salt solution concentration and freezing point is as follows:
℃ -3 ℃
℃ -7 ℃
℃ -10.8 ℃
℃ -16.3 ℃
℃ -21.2 ℃
4. Resin placed in the exchanger for a long time out of use. In order to prevent irreversible pollution of the resin by microorganisms (such as algae, bacteria, etc.), the resin must be thoroughly backwashed before removal to remove suspended matter accumulated during operation, Pay attention to regular flushing and water changes.
