1Storage upon arrival: After the resin arrives at the site, the type and quantity should be promptly counted, and the packaging should be checked for completenessSeal tightly and store indoors as much as possible. When storing resin outdoors, it should be separated and stored in a cool place, away from sunlightDirectly shining, with wooden boards at the bottom and plastic cloth covering the surface.

2Anti dehydration: The resin contains a certain amount of balanced moisture, which should be kept moist during storage and transportation to prevent dehydrationStop dehydration. Resin should be stored indoors or covered, with an ambient temperature of 5°C -40°CIt is advisable to avoid direct sunlight, stay away from heating devices such as boilers and heaters, and avoid dehydration.

If dehydration is found in the resin, do not directly put the resin in water to avoid rapid contact of dry resin with waterSwelling and shattering. It should be used according to its degree of dehydration 10%Slowly add salt water on both sides to the resin and soak itDilute gradually with clean water after a few hours

3Antifreeze: When the ambient temperature is 0°CTo prevent the resin from cracking due to internal moisture freezing, Insulation measures should be taken, or the resin should be stored in salt water of corresponding concentration according to temperature conditions to prevent freezing.If the resin is found to have frozen, it should be allowed to thaw slowly and naturally, and mechanical force should not be applied to the resin. The relationship between the concentration of salt solution and freezing point is shown in the following table:

4Shutdown and storage: Resin should be soaked in clean water for long-term storage or in equipment that needs to be stopped for a long time. If the water needs to be drained when the equipment is stopped, it should be sealed to prevent the loss of moisture in the resin.

5Microbial prevention: resin placed in the exchanger after long-term disuse to prevent microorganisms（Like algaeBacteria, etc）For irreversible pollution of resin, the resin must be backwashed before shutdown to remove suspended substances accumulated during operation, and attention should be paid to regular flushing and water replacement.

In addition, during storage and transportation, the resin should avoid direct contact with iron containers, oxidants, and oils and fatsQuality is used to prevent resin from being contaminated or oxidized, which may cause resin degradation.
