Product Introduction:
Ion exchange resin is a polymer compound with functional groups
(active groups that exchange ions), a network structure, and
insolubility. Usually spherical particles. The full name of ion
exchange resin consists of classification name, skeleton (or group)
name, and basic name.
The pore structure is divided into gel type and macroporous type.
Any resin with physical pore structure is called macroporous resin,
and "macropore" is added before the full name. For those classified
as acidic, add "yang" before the name, and for those classified as
alkaline, add "yin" before the name. For example, macroporous
strongly acidic styrene based cation exchange resin.

Product Usage:
1. Water treatment
The demand for ion exchange resins in the field of water treatment
is high, accounting for about 90% of the production of ion exchange
resins, which are used for the removal of various cations and
anions in water. At present, the maximum consumption of ion
exchange resin is used for pure water treatment in thermal power
plants, followed by atomic energy, semiconductor, electronics
industry, etc.
2. Food industry
Ion exchange resin can be used in industrial equipment such as
sugar refining, monosodium glutamate, alcohol refining, and
biological products. For example, the production of high fructose
corn syrup involves extracting starch from corn, followed by
hydrolysis reaction to produce glucose and fructose, and then ion
exchange treatment to produce high fructose corn syrup. The
consumption of ion exchange resin in the food industry is second
only to water treatment.
3. Pharmaceutical industry
Ionic exchange resins in the pharmaceutical industry play an
important role in the development of new generation antibiotics and
the quality improvement of existing antibiotics. The successful
development of streptomycin is a prominent example. In recent
years, there have been studies on the commission of traditional
Chinese medicine.
4. Synthetic chemistry and petrochemical industry
In organic synthesis, acids and bases are commonly used as
catalysts for esterification, hydrolysis, ester exchange,
hydration, and other reactions. Using ion exchange resin instead of
inorganic acids and bases can also carry out the above reactions,
and has more advantages. Resin can be reused repeatedly, the
product is easy to separate, the reactor is not corroded, does not
pollute the environment, and the reaction is easy to control. The
preparation of (MTBE) uses macroporous ion exchange resin as a
catalyst, which is formed by the reaction of isobutene and
methanol, replacing the original tetraethyl lead that can cause
serious environmental pollution.
5. Environmental Protection
Ion exchange resins have been applied in many highly concerned
environmental protection issues. Currently, many aqueous or
non-aqueous solutions contain toxic ions or non-ionic substances,
which can be recycled using resins. Such as removing metal ions
from electroplating wastewater and recovering useful substances
from film production wastewater.
6. Wet metallurgy and others
Ion exchange resin can separate, concentrate, purify uranium and
extract rare earth elements and precious metals from depleted
uranium ore.
