Ion Exchange Resin’s Storage and Transport
2013-09-29 Source： Author：佚名 Read：次
During the period of the storage, we should change the strong acid or strong base resin to Cl
form, and the weak acid or weak base resin to H form or free amine form in order to keep their
capability, then put them into the pure water for storage. If the ion exchange resins were in the
machine, pour out the water, and keep the machine airproof to protect the moisture content of
the resins.There is moisture inside of the resins, so we should keep the resin wet in the transport.
The temperature of 5~40℃ will be the best. And the storage place should apart from the heater.
If the resin lack of moisture, please put the resin in to 10% NaCl solution slowly, and dunk it
for a few hours, then use the pure water to wash, that can retrieve the moisture.If the temperature
is below 0℃, we should put the rein into NaCl solution to protect the moisture content of the
resins.
After using the resin, if you want to store them for a long period, you would better to wash them
with pure water in the way as follow, that can avoid the pollution from algae and bacterium:Anion
exchange resin: Using 10% NaCl and 2% NaOH mixed solution to pass the resin bed for twice.
The amount is 3 times larger than the resin bed, and then, wash it. If necessary, it is better to
wash the resin with 0.2% H2O2 before to use it again.Cation exchange resin: you can fill 0.5%
formaldehyde into the cation exchange resin bed, and keep this consistence during the storage time.
And wash the resin with 0.2% H2O2 or 0.5% formaldehyde before to use it again.
Remark:
①To be stored in sealed vessels, avoid freezing or violent sun-shine.
②Storage temperature: 4- 40℃.
③Storage expiry is 2 years. If storage is over 2 years, the product should be reinspected before use.
If the resin is found water loss, you are not allowed to add water directly to the resin.
You should first add just right amount of thick salt water to it, making the resin become wet again.
