Ion Exchange Resin Supplier in China - High-Quality Products from Our Factory
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. Swelling & Transformation
Reflects the volume change rate 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 the 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.
Frequently Asked Questions
What is an ion exchange resin?
An ion exchange resin is an insoluble polymer compound with a network structure containing functional groups (active groups) capable of ion exchange. They are typically spherical particles consisting of a spatial skeleton that supports the compound and active groups that perform the exchange action.
What are the differences between gel type and macroporous type resins?
The classification is based on the pore structure. Macroporous type resins have a physical pore structure, whereas gel type resins present a transparent or translucent gel form without permanent physical pores.
How do cation and anion exchange resins differ?
Cation exchange resins are capable of exchanging cations in water, while anion exchange resins are capable of exchanging anions in water.
What are the primary performance indicators of ion exchange resins?
The key performance indicators include particle size, density, water content, volume change rate of swelling and transformation, exchange capacity, and mechanical strength.
Where are these resins mainly applied?
They are suitable for desalination or ultrapure water treatment. They are widely utilized across various industries, including electronics, electric power, petroleum, and chemical industries.
