Overview

The macroporous strongly acidic cation exchange resin * r $n is first treated with saturated saline solution, which is approximately twice the volume of the treated resin. The resin is soaked in the saline solution for 18-20 hours, then the saline solution is drained and rinsed 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 using a 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.

Macroporous strongly acidic cation exchange resin*The main reason for the freezing of Jinda softened water resin is that it contains a certain amount of moisture when it leaves the factory. Therefore, in cold winter, it is necessary to take anti freezing measures for Jinda softened water resin to prevent the overall performance from deteriorating or even losing its properties after freezing. This article introduces the main reasons for the freezing of Jinda softened water resin.
Jinda Softened Water Resin
In winter, the temperature is generally low due to the influence of cold and humid air currents. If the resin is soaked and stored in water or liquid, it is easy to freeze the resin. As a result, the water in the resin pores turns into ice, and the volume expands, damaging the resin structure and performance strength, increasing the resin breakage rate, and reducing the resin's service life. Therefore, it is necessary to take anti freezing measures for Jinda softened water resin in winter, especially in areas with lower temperatures such as Northeast China and Inner Mongolia.
Jinda Softened Water Resin
When storing Jinda resin antifreeze measures, Jinda softened water resin can be soaked in a sodium solution with a concentration between 20% and 25%. And it should be kept in an environment with a temperature between five and forty degrees Celsius, avoiding overcooling or overheating.
Jinda Softened Water Resin
If storage conditions do not permit and there are no anti freezing measures in winter, Jinda resin can be stored in 10% saline water. If the resin is accidentally frozen, do not melt it instantly at high temperatures. Instead, allow the resin to thaw naturally in a low-temperature environment. The moisture in resin is the main cause of resin freezing, but the moisture contained in ion exchange resin is very important, and it should be kept as much as possible during transportation and storage. Introduction to the explanation of the regeneration degree of Jinda ion exchange resin related to its impact.
Technical principle of Jinda ion exchange resin Part 1: Explanation of the influence on the regeneration degree of Jinda ion exchange resin

The utility model discloses a wastewater treatment device for producing phenolic resin, comprising a water supply tank. A cation resin tower, an anion resin tower, and a water collector are further arranged next to the water supply tank. The cation resin tower, anion resin tower, water collector, and water supply tank are sequentially connected in series through pipelines; The electroplating wastewater is collected by a water collector and transferred to a resin tower through pipelines. The adsorption capacity of the anion and cation exchange resin in the resin tower for heavy metals in the electroplating wastewater is used to purify the wastewater; The beneficial effect of this utility model is that heavy metals can be recovered and utilized through the reverse exchange reaction of the resin tower, while meeting the national heavy metal wastewater discharge standards.
