Overview

Softening water equipment resin weakly acidic cation resin professional direct seller $r $n ion exchange tree fat contains a certain amount of water, and this water should be kept as much as possible during transportation and storage. If the resin loses water during storage, it should be soaked in concentrated saline water (-10%) first, and then gradually diluted. It should not be directly placed in water to avoid rapid expansion and breakage of the resin. In long-term storage, strong type resins should be transformed into salt type, while weak type resins can be transformed into corresponding hydrogen type or free base type or salt type, and then soaked in clean water. During storage or transportation, the resin should be kept in a temperature environment of 5-40 ° C to avoid overcooling or overheating

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.

These active intermediates can adsorb various non-ionic substances such as activated carbon, and expand their functions through molecular adsorption generated by the work ability of Van der Waals molecules. Macroporous resins without exchange functional groups will also adsorb and separate various substances, such as phenols in chemical plant wastewater. Macroporous resins have many large pores, large surface area, many active intermediates, fast ion diffusion speed, and much faster ion exchange speed, which is about 10 times faster than gel resins. The utility model has the advantages of quick effect, high power level, and shorter processing time. Macroporous resins also have many flash points: they are resistant to expansion, cracking, oxidation, friction damage, heat and temperature changes. In addition, They are conducive to the adsorption and exchange of organic macromolecules, so they have a strong anti pollution.

Ion exchange resins consist of classification names, skeleton (or gene) names, and basic names.
In addition, it is beneficial for regeneration The ion exchange capacity of ion exchange resin and its performance in ion exchange reactions are listed in its "ion exchange capacity".

The pore structure is divided into gel type and macroporous type. Any resin with physical pore structure is called macroporous resin, and "macroporous" is added before the full name.
For macroporous resins, there are some manufacturers and varieties of ion exchange resins both domestically and internationally. The brand of the resin is mainly determined by any manufacturer or their location in China. Some foreign products use the letter C to represent cationic resins (C is the first letter of cation) and A to represent anionic resins (A is the first letter of anion). For example, Amberlite's IRC and IRA are positive and negative resins, respectively, and also represent positive and negative resins. According to the regulations of the Ministry of Chemical Industry of China (HG2-884-76), the type of ion exchange resin consists of three numbers, with the first number representing the product classification: 0 represents strong acidity, 1 represents the product classification. Represents weak acidity, 2 represents strong alkalinity, and 3 represents weak alkalinity.

For those classified as acidic, add "yang" before the name, and for those classified as alkaline, add "yin" before the name.
