Featured property of Super Absorbent Polymer
Stability
- Super absorbent resins used as water-absorbent materials are bound to be subject to external conditions such as light, heat, chemicals and others.
- The effect of the condition changes its water absorption performance. Therefore, the stability of the superabsorbent resin mainly includes thermal stability and light.
- Stability and storage stability, etc. Different types of superabsorbent resins have different stability when they absorb water, such as polyacrylates.
- The resin-like resin increases in thermal stability as the degree of crosslinking increases. At room temperature, the super absorbent resin can be stored in a closed container for 3 to 5 years.
- Its water absorption capacity is constant and its stability is very good.
-
Thickness
- Super absorbent resin gel has special rheological properties, thickening is its remarkable property, and a small amount of resin can make the solution
- The viscosity is greatly improved. Taylor studied the thickening mechanism of superabsorbent resin gels and found that due to the high water-absorbent resin in water
- Highly swellable, absorbing solvent, the solution system is densely packed with swollen resin particles, becoming dense, and the viscosity of the solution is significantly increased
- In addition to the above properties, the superabsorbent resin also has special properties such as ammonia absorption, diffusion, safety and compatibility.

Introduction Of Super Absorbent Polymer
Super Absorbent Polymer; (SAP) is a new functional polymer material. It has a high water absorption function of absorbing water several hundred to several thousand times heavier than itself, and has excellent water retention performance. Once the water swells into a hydrogel, it is difficult to separate the water even if it is pressurized. ,
The superabsorbent resin is a functional polymer material having a large amount of hydrophilic groups. With its high liquid absorption capacity, high liquid absorption speed and high liquid retention capacity, it is widely used in sanitary products such as women's sanitary napkins, diapers, adult multifunctional nursing pads, absorbent paper, pet pads, as well as agriculture plants and so on. This kind of product is greatly lightened, miniaturized and comfortable, which brings good news to people and is an irreplaceable ideal product in the field of hygiene products and agriculture plants.
Applications of Super Absorbent Polymer(SAP)
1. Application in agriculture and horticulture
Superabsorbent resins for agriculture and horticulture are also known as water retention agents and soil amendments. China is a country with severe water shortage in the world. Therefore, the application of water retention agent has become more and more important. At present, more than a dozen research institutes in China have developed superabsorbent resin products for grain, cotton, oil and sugar. More than 60 kinds of plants, such as tobacco, fruit, vegetables and forests, have been applied for more than 70,000 hectares, and large-area sand-proof afforestation has been carried out in the northwest and Inner Mongolia using superabsorbent resins. The superabsorbent resin used in this aspect is mainly a starch grafted acrylate polymerization crosslinker and an acrylamide-acrylate copolymer crosslinker, wherein the salt has shifted from a sodium form to a potassium form. The methods used mainly include seed dressing, spraying, hole application, or mixing with water.
Soak the roots of the plants after the shape. At the same time, it is also possible to apply fertilizer after coating the fertilizer with a super absorbent resin, and fully utilize the utilization rate of the fertilizer to prevent waste and pollution. Foreign countries also use super absorbent resin as a fresh-keeping packaging material for fruits, vegetables and food.
2, in medical and health applications
Mainly used as sanitary napkins, baby diapers, napkins, medical ice packs; gel-like daily fragrance materials used to adjust the ambient atmosphere. It is used as a matrix medical material for ointments, creams, liniments, cataplasms, etc., and has the functions of moisturizing, thickening, skin infiltration and gelation. It can also be made into a smart carrier that controls drug release, release time, and release space.
3. Industrial applications.
The industrial moisture-proofing agent is produced by the function of high-absorbent resin high-temperature water absorption and low-temperature release of water. In oilfield oil recovery operations, especially in oilfield operations in the old oilfields, the use of ultra-high molecular weight polyacrylamide aqueous solutions for oil displacement is very good. It can also be used for dehydration of organic solvents, especially for organic solvents with low polarity. There are also industrial thickeners, water-soluble paints and the like.
4. Application in construction
The water-swelling rapid expansion material used in water conservancy projects is a pure superabsorbent resin, mainly used for plugging dam holes in flood season, blocking water in basement, tunnel and subway prefabricated joints; for urban sewage treatment and dredging works The mud is solidified for easy digging and transportation. Since the superabsorbent polymer is non-toxic, non-irritating to the human body, has no side reaction, and does not cause blood coagulation, it has been widely used in the field of medicine in recent years. For example, it is used for a topical ointment with a large water content and a comfortable use; a medical bandage and a cotton ball capable of absorbing surgery and traumatic bleeding and secretions, and preventing purulence; and an anti-microbial resistance that can pass moisture and chemicals Infectious artificial skin, etc. In the electronics industry, superabsorbent polymers can also be used as humidity sensors, moisture measurement sensors, and water leak detectors. The superabsorbent polymer can be used as a heavy metal ion adsorbent and an oil absorbing material. Other applications
In addition to the above aspects, superabsorbent resins are used in household chemicals, petroleum industry, environmental protection industry, fiber industry, and electronics industry.
Industry and other aspects also have broad application prospects. Superabsorbent resins are also well used in daily life. Such as food
Superabsorbent resins such as preservatives, cosmetic additives, perfume slow release agents, oil field treatment agents, etc. have all played a huge role.
Conclusion:
Super absorbent resin(polymer) has been widely used in sanitary ware due to its excellent water absorption and water retention.
Materials, agriculture, forestry and gardening, dehydrating agents, chemical cold storage agents, heat storage agents, sludge solidifying agents, wall materials for dew prevention, food preservatives,
Water-swellable coatings and composite absorbent materials. As a result, its production capacity has increased rapidly, especially in the United States and Japan.
The annual output has exceeded 200,000 tons.
