1. Pre 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;

Afterwards, use 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.

2. Pre treatment of Yin Resin

The steps in its pretreatment method are the same as those in the cation resin pretreatment 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.

After sales specification for macroporous strong acidic cation exchange resinAnalysis of factors affecting the performance of pure water exchange resin: The discovery of Jinda pure water exchange resin and its application in various industries were initially developed abroad. The early Chinese people did not discover this advantageous substance. After more than ten years of development, resin products began to enter the Chinese market. In just a few years, resin has been widely used and developed in China.
Factors affecting the performance of Jinda pure water exchange resin
1. The high inlet water temperature of the equipment can accelerate the replacement speed of the ion resin, but high temperature refers to a certain control range. If the water temperature exceeds the specified value, it will damage the structure of the resin itself and affect normal operation and replacement.
2. In some areas, water contains high valence metal ions such as Fc3+, AL3+, Cr3+, etc. If these ions are not treated, they can come into contact with resin and cause resin poisoning; If there are oxidizing substances in water, they will oxidize and decompose the resin, so oxidizing substances are also a factor affecting the working performance of the resin.
3. In some areas, natural water quality may contain some oils and fats, which can adhere to and surround resin particles, making it impossible for the resin to undergo displacement. In addition, if the resin adsorbs too much suspended solids in the water, the same phenomenon may occur. Therefore, it is necessary to pay attention to the impact of these substances on the resin.
Jinda resin
The wide application of Jinda pure water exchange resin
As a chemical product, ion exchange resin is widely used in people's daily life and production. Its main application areas include food processing industry, pure water preparation industry, pharmaceutical manufacturing industry, petroleum refining industry, and metallurgical manufacturing industry. With the rapid development between different industries, ion exchange resin is also constantly improving in terms of performance and processing capacity.

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.
