Ion resin is often divided into two types: gel type and macroporous type. The polymer skeleton of gel-type resin has no pores in dry conditions. It swells when it absorbs water, forming very fine pores between macromolecular chains, commonly known as micropores or ion exchange resin.

Ion exchange resin is widely used because of its characteristics. There are countless domestic manufacturers of ion exchange resin for sale, and Sunresin, a professional manufacturer of ion exchange resin, is trustworthy. So what are the main applications?

Chinese resin manufacturers have a very large production scale and consumer market. In 2014, total production of synthetic resins in the domestic reached 69.507 million tons. Among them, polyethylene is 13.366 million tons, an increase of 13.8% over the same period last year.

Chinese resin manufacturers have made remarkable achievements in the development of domestic catalysts, processes and equipment. In particular, the developed catalysts for polyethylene and polypropylene are not only widely used in domestic large-scale industrial plants, but also exported to foreign countries. Large-scale polyethylene gas phase technology is also under development. Some new high value-added polyolefin products, such as high-speed stretching BOPP film material, HDPE gas pipe material, transparent polypropylene material, automobile fuel tank material, washing machine material, polypropylene block copolymer material, PP-R/PP-B pipe material, have also achieved large-scale industrial production, and they have gained a certain market share.

Ion exchange resin is a kind of macromolecule compound with functional group (active group of exchange ion), network structure and insolubility. Its full name consists of classification name, skeleton (or gene) name and basic name.

Advantages of adsorbent resins 1. Adsorbent resin is adsorbable due to the van der Waals force and hydrogen bond between them and the adsorbed molecules. 2. Adsorbent resins have screening properties. They can selectively adsorb organic substances from solution, so that organic compounds can be separated by solvent elution according to their adsorptive power and molecular weight to achieve different purposes of separation, purification, impurity removal and concentration.

The weak anion exchange resin is divided into macroporous type and gel type, and the skeleton is divided into styrene and acrylic acid system. The strong anion exchange resinis also divided into macroporous type and gel type, and the skeleton is also divided into styrene and acrylic acid systems. Styrene resin belongs to rigid sphere, while acrylic resin sphere has better toughness.

Ion exchange resin, as a special macromolecule compound with selective adsorption and exchange functions, has played an important role in industry, agriculture, processing and manufacturing industries. It can be predicted that ion exchange resins will play a more important role in the future with the continuous development of various industries and the progress of science and technology.
