Yin Yang ion exchange resin manufacturer [Honest manufacturer, trustworthy]Transportation and storage of resin:

Ion exchange resin contains a certain amount of moisture, which should be maintained as much as possible during transportation and storage. If the resin loses water during storage, it should be soaked in concentrated saline water (8-10%) for 1-2 hours before gradually diluting. It should not be directly placed in water to avoid rapid expansion and breakage of the resin. During storage or transportation, the resin should be kept in a temperature environment of 5-40 ℃ to avoid overcooling or overheating, which may affect its quality. If there is no insulation equipment in winter, the resin can be stored in saline solution, and the temperature of the saline solution can be determined according to the temperature.

IIYin Yang ion exchange resin manufacturer [Honest manufacturer, trustworthy]Pre treatment of new resin:

New resins often contain solvents, substances that have not participated in polymerization reactions, and small amounts of low polymers, and may also adsorb heavy metal ions such as iron, aluminum, and copper. When the resin comes into contact with water, acid, alkali, or other solutions, the soluble impurities mentioned above will be transferred into the solution, contaminating the effluent quality in the early stages of use. So, the new resin needs to be pre treated before being put into operation.
1Pre treatment of Yang resin

The pretreatment steps for cation resin are as follows：

Firstly, use saturated saline solution, which is approximately twice the volume of the treated resin. Soak the resin in the saline solution for 18-20 hours, then drain the saline solution and rinse with clean water to ensure that the discharged water does not turn yellow;
Next, use a 2% -4% NaOH solution with the same amount as above, soak in it for 2-4 hours (or clean with a small flow rate), drain the alkaline solution, and rinse the resin until the discharged water is close to neutral; After Zui, use 5% HCl solution with the same amount as above, soak for 4-8 hours, drain the acid solution, and drift with clean water until neutral for later use.

2Pre treatment of Yin Resin

The * step in its preprocessing method is the same as the * step in the cation resin preprocessing method; Then soak in 5% HCl for 4-8 hours, drain the acid solution, and wash with water until neutral; Then soak in a 2% -4% NaOH solution for 4-8 hours, drain the alkaline solution, and wash with clean water until neutral for later use.
