One . Transportation and storage of resin:
Ion exchange resin contains a certain amount of water, and this part of water should be kept as much as possible during transportation and storage.
If the resin is dehydrated during storage, it should be soaked in concentrated salt water (-) for an hour and then gradually diluted. Do not place it directly in water to prevent the resin from rapidly expanding and breaking. During storage or transportation, resin should be kept in a temperature environment of -°C to avoid overcooling or overheating, which may affect the quality. If there is no thermal insulation equipment in winter, the resin can be stored in salt water. The temperature of the salt water can be determined according to the air temperature.
2. Pretreatment of new resin:
New resin often contains solvents, substances that have not participated in the polymerization reaction and a small amount of low polymers, and may also absorb heavy metal ions such as iron
, aluminum, and copper. When the resin comes into contact with water, acid, alkali or other solutions, the above-mentioned soluble impurities will be transferred into the solution, polluting the quality of the effluent water in the early stage of use. Therefore, new resin must be pre-treated before being put into operation.
Pretreatment of cation resin
The steps for pretreatment of cation resin are as follows:
First, use saturated salt water in an amount approximately equal to twice the volume of the resin to be treated, and place the resin in food.
Soak in salt solution for - hour, then drain out the salt water and rinse with clean water so that the discharged water does not have yellow color
Next, use - solution, the amount is the same as above, in Soak it for - hours (or clean with a small flow rate
). After draining the alkali solution, rinse the resin until the discharged water is close to neutral
Finally, use the solution, the amount of which is the same as above, soak for - hours. Drain the acid and rinse with clean water
until it becomes neutral and set aside for later use.
Pretreatment of anion resin
The first step in the pretreatment method is the same as the first step in the cation resin pretreatment method, and then soaked with
for - hour, and then drain the acid. , wash with water until neutral and then use
