Ion exchange resin is a polymer compound, so its performance is different from the manufacturing process, raw material, polymerization temperature, crosslinking agent and so on. Its main properties are divided into two parts..

(1) physical performance

The appearance of resin is a transparent or translucent material, because of its composition, different colors, such as styrene resin was yellow, but also a black and brown, but little impact on the performance. Under normal circumstances, raw materials impurities or more crosslinking agent, resin color slightly deep (but resin in the running process, because of various reasons sometimes color will change). Resin spherical shape, requirements of ball rate reached more than 90%.
The particle size of resin particle size will influence the exchange rate, pressure loss, backwash effect. The particle size can't vary too much. The particles of the ion exchange resin for water treatment are 40 ~ 20 mesh and appropriate.. The representation of the particle size is represented by the effective particle size and the inhomogeneous coefficient..
The density of water treatment process and resin filling quantity. The method of the density is: dry density (average 1.6g/cm3), wet true density (generally 1.04 ~ 1.30g/cm3), apparent humidity density (usually between 0.60 ~ 0.80g/cm3).
The moisture content of the resin ratio, said the higher the porosity, the smaller the degree of crosslinking.
The swelling rate of resin soaking after swelling, and crosslinking degree, active groups, exchange capacity, water electrolyte density, ion exchange properties and so on. In the process of exchange and regeneration, the resin can swell and shrink, and many times expansion and shrinkage resin can easily break..
The wear resistance reflects the mechanical strength of resin. It should ensure that the annual consumption of resin is no more than 7%.
To gradually dissolve the polymer containing low solubility resin glue, soluble resin used in the process will also.
The heat resistant temperature of 100 DEG C Yang resin, strong base anion resin can withstand 60 DEG C, weakly basic anion exchange resin high temperature 80 DEG C. But when it is below or equal to 0, it is easy to freeze and break..
I do not conductive conductive resin, the resin can be wet conductivity.
(2) chemical properties
The exchange reaction of the ion exchange resin is reversible, so it can be exchanged and regenerated and can be used repeatedly..
Have acid, alkaline. The properties of H+ type cation exchange resin and OH- anion exchange resin are the same as that of electrolyte acid and alkali, and can be able to produce the ability of OH- and H+ in water..
Has the neutralization and hydrolysis performance. Because of its electrolyte properties, and acid, alkali and neutralization reaction, can also be hydrolyzed.
The ion exchange resin adsorption ability of various ions in a selective.
The exchange capacity. How much is the amount of its exchange ion. According to the morphology of the resin can be divided into the exchange capacity, total exchange capacity, exchange capacity, etc..
