Resin introduction:

Ion exchange resin, is a kind of functional group (has the active group of ion exchange) with a network structure, insoluble polymer compounds. They are usually spherical particles. Ion exchange resins consist of a skeleton with a large spatial structure that supports the whole compound and an active group that provides an ion exchange action.

According to the pore structure, there are two kinds: gel type and macroporous type. The resin with physical pore structure is called macroporous type, and the resin with transparent or translucent gel form is called gel type. According to the nature of the active group is divided into two kinds of cation and anion exchange resin, can and water cation exchange resin called "cation exchange resin", can and water anion exchange resin called "anion exchange resin".

Resin performance indicators:

1. Particle size: it mainly reflects the index of "effective particle size" and "uniformity coefficient";

2. Density: it is divided into "wet apparent density" and "wet true density";

3. Water content: reflects the index of "crosslinking degree" and "porosity";

4. Volume change rate of swelling and transformation: reflect the index of "shrinkage" and "expansion";

5. Exchange capacity: the working exchange capacity is an important indicator reflecting the size of the exchange capacity;

6. Mechanical strength: the index of the impact resistance of resin.

Scope of application:

It is suitable for the treatment of desalination or ultrapure water. It is widely used in electronics, electric power, petroleum, chemical industry and other industries.
