Development and Application of Super Absorbent Polymer

Super absorbent polymer (SAP), also known as AMAZING super absorbent powder, is a new type of functional polymer materials. Its water absorption ratio can be up to mass hundreds of thousands of times. The first superabsorbent resin was developed in 1974 by the US Department of the North Institute of the hydrolysis of starch grafting acrylonitrile copolymer, but in the early 1980s Japan's super absorbent resin development technology is dominated all over the world.

Although development time of high absorbent resin more short, but all aspects development are very fast. As 1983 world total output was up to 6000 metric tons and in 1987 only the Japan’s production on reached was 36000 metric tons; currently there are 30-40 manufacturers to produce super absorbent polymer in the world, main located in Japan, United States and the European; super absorbent polymer product is also developed from starch grafted acrylonitrile to starch grafted acrylic acid, cross-linked cellulose, polyacrylic acid salt, copolymer hydrolysis, polyether, polyurethane and other categories; while the water absorption capacity of superabsorbent resin from a hundred times in the 1980s to four or five thousand times at present.

Applications of Super Absorbent Polymer:

In agriculture and horticulture

For agricultural and horticultural aspects of the super absorbent resin, is also known as water retention agent and soil conditioner. China is the world's more serious water shortage countries, therefore, the application of water-retaining agent is becoming more and more important, the current domestic research institutes have developed more than a dozen highly absorbent resin products for grain, cotton, oil, sugar , Tobacco, fruit, vegetables, forest and so on more than 60 kinds of plants on the application of the test, to promote an area of more than 70,000 hectares, and in the northwest, Inner Mongolia and other places using high water absorption resin for large-scale sand a forestation.

In medical, health applications

Mainly used for sanitary napkins, baby diapers, napkins, medical ice bag; used to regulate the atmosphere of the colloidal daily aromatic materials. For ointment, cream, liniment, cataplasm and other matrix medical materials, with moisturizing, thickening, skin infiltration, the role of gel. Also it can be made into the control of drug release, release time, the release of space intelligent carrier.

In industrial applications

It use the super absorbent polymer at high temperature absorb water and release water at low temperature for production of industrial moisture-proof agent. In the field of oil production, especially in the old field of oil production operations, the use of ultra-high molecular weight polyacrylamide aqueous solution for oil displacement effect is very good. Can also be used for organic solvent dehydration, especially for small polar organic solvent dehydration effect is very significant. There are industrial thickeners, water-soluble coatings.

In the construction of the application

In the water conservancy project uses the water swells the material, is the pure super absorbent resin, mainly uses in the flood season the big dam hole plugging, the basement, the tunnel, the subway prefabricated sewer water shutoff; Uses in the city sewage treatment and the dredging project Of the mud curing, in order to facilitate excavation and transportation.

Our company mainly supplies the SAP (super absorbent polymer) for hygiene products, such as baby diaper, adult diaper, feminine sanitary napkin, incontinence pads, etc. Any interest please feel free to contact us.
