Super absorbent resin manufacturer

With the rapid development of chemical industry, many new chemical materials appear in our lives. Super absorbent resin is one of them. Super absorbent resin is a new polymer composite. Super absorbent resin can absorb hundreds to thousands of times its own weight of water, in addition, super absorbent resin is non-toxic, harmless and pollution-free; Strong water absorption capacity and high water retention capacity. Therefore, super absorbent resin is more and more favored by people. Next, Bian Xiao will tell you about super absorbent resin.

Super absorbent resin manufacturer

Super absorbent resin is a new polymer material, which can absorb hundreds to thousands of times its own weight of water, and is non-toxic, harmless and pollution-free. Strong water absorption capacity and high water retention capacity. High molecular weight polymer obtained by acrylic acid polymerization → high water retention capacity, balance of absorption capacity under high load, absorbed water can not be squeezed out by simple physical methods, and water can be released and absorbed repeatedly.

1, Wuhan Yuancheng Technology Development Co., Ltd. is a large-scale comprehensive high-tech enterprise integrating R&D, production, management and e-commerce sales of organic chemicals, pharmaceutical raw materials, pharmaceutical intermediates, food additives and chemical raw materials, and is committed to becoming a top supplier in China.

2. The main products of yanggu county Fiona Fang Chemical Plant are: polyacrylamide, sodium polyacrylate, potassium polyacrylate, carboxymethyl cellulose, water-retaining agent, polymer water-absorbing resin, papermaking additives, etc.

3. Shandong Xinhao Polymer Materials Co., Ltd. is a high-tech enterprise specializing in the production of polymer absorbent resin and special powder for optical cables. The company was officially put into production in 2002, covering an area of 20,000 square meters with a total investment of 50 million yuan.

Characteristics of super absorbent resin

1. Super absorbent? It can absorb hundreds or thousands of times its own weight of deionized water.

2. High water absorption? Each gram of super absorbent resin can absorb hundreds of grams of deionized water in 30 seconds.

3. High water retention? Under external pressure, water is not easily squeezed out of the gel after water absorption.

4. High scalability? The volume of super absorbent resin gel expands hundreds of times after absorbing water.

5. Absorb ammonia? The molecular structure of low cross-linked polyacrylate superabsorbent resin contains carboxyl anions, which can be adsorbed when it meets ammonia, and the deodorization effect is obvious.

Types of super absorbent resins

Classification according to the source of raw materials

With the deepening of the research on super absorbent resin, the traditional classification method of super absorbent resin into starch series, cellulose series and synthetic resin series can no longer meet the classification requirements. Therefore, Professor Zou Xinxi put forward six series of classifications according to his own research results.

Starch series: including grafted starch, carboxymethyl starch, phosphate esterified starch, starch xanthate, etc.

Cellulose series: including grafted cellulose, carboxymethyl cellulose, hydroxypropyl cellulose, xanthate cellulose, etc.

Synthetic resin system: including polyacrylate, polyvinyl alcohol, polysiloxane, inorganic polymer, etc. [ 1]

Protein series: including soybean protein, silk protein, gluten, etc.

Other natural products and their derivatives: including pectin, alginic acid, chitosan, heparin and so on.

* * * mixtures and composite systems: including * * superabsorbent resin mixtures, composites of superabsorbent resin and inorganic gel, composites of superabsorbent resin and organic matter, etc.

Depending on the type of hydrophilic group.

Anion system: including carboxylic acid, sulfonic acid, phosphoric acid, etc.

Cationic system: including tertiary amine, quaternary amine, etc.

Zwitterionic system: including carboxylic acid-quaternary amine and sulfonic acid-tertiary amine;

Non-ionic system: including hydroxyl group, amide group, etc.

Various hydrophilic groups: including hydroxycarboxylic acid, hydroxycarboxylic acid amide group, sulfonic acid carboxylic acid group, etc.

The above is Bian Xiao's detailed knowledge about super absorbent resin. I hope our sharing can help you better understand super absorbent resin. Super absorbent resin has applications in many fields of our lives. Super absorbent resin not only has high water absorption, but also has the functions of absorbing ammonia and deodorizing. And the expansion coefficient of super absorbent resin is very high. Widely used in agriculture and forestry production, urban landscaping, drought and water conservation, sand control and other fields. It is conceivable that super absorbent resin is becoming more and more popular.
