Super Absorbent Polymer (SAP) is a new type of functional polymer material. It has a high water absorption function that can absorb water hundreds to thousands of times its own weight, and has excellent water retention properties. Once it absorbs water and swells into a hydrogel, it is difficult to separate the water even if it is pressurized. Super absorbent resin is a functional polymer material with a large number of hydrophilic groups.
Due to its high liquid absorption capacity, high liquid absorption speed and high liquid retention capacity, water-absorbent resin is widely used in physiological hygiene products, such as women's sanitary napkins, diapers, adult multi-functional nursing pads, absorbent paper, pet pads, etc. This type of product is greatly lighter, smaller and more comfortable, which brings good news to people and is an irreplaceable ideal product in the field of sanitary products.

Application areas
1. Applications in agriculture and horticulture: Super water-absorbent resins used in agriculture and horticulture are also called water-retaining agents and soil improvers.
2. Applications in medical and sanitary applications: mainly used as sanitary napkins, baby diapers, napkins, and medical ice bags; colloidal daily aromatic materials used to adjust the environmental atmosphere. It is used as a base medical material for ointments, creams, liniments, cataplasms, etc. It has the functions of moisturizing, thickening, skin infiltration, and gelling. It can also be made into an intelligent carrier that controls drug release amount, release time, and release space.
3. Application in industry Use the function of super absorbent resin to absorb water at high temperatures and release water at low temperatures to make industrial moisture-proof agents. In oil field production operations, especially in old oil fields, the use of aqueous solutions of ultra-high molecular weight polyacrylamide for oil displacement is very effective. It can also be used to dehydrate organic solvents, especially for organic solvents with low polarity. The dehydration effect is very significant. There are also industrial thickeners, water-soluble coatings, etc.
4. Application in construction: The material that expands quickly when exposed to water is a pure super absorbent resin used in water conservancy projects. It is mainly used for plugging leaks in dam holes during flood seasons, and for plugging water in basements, tunnels, and subway prefabricated joints; Slurry solidification for urban sewage treatment and dredging projects to facilitate excavation and transportation, etc.
5. Application in toys: Water-absorbent resin can be used to make "sea babies" and "artificial snow" that are popular on the market.
Environmentally friendly and non-toxic properties Since super absorbent polymers are non-toxic, non-irritating to the human body, have no side effects, and do not cause blood coagulation, they have been widely used in the medical field in recent years. For example, it is used for external ointments with high water content and comfortable use; the production of medical bandages and cotton balls that can absorb bleeding and secretions from surgery and trauma, and prevent suppuration; and the production of antibiotics that can allow water and pharmaceuticals to pass through but microorganisms cannot penetrate. Infectious artificial skin, etc.
With the development of science and technology, environmental protection has attracted more and more attention. If the super absorbent polymer is put into a bag that is soluble in sewage and the bag is immersed in the sewage, when the bag is dissolved, the super absorbent polymer can quickly absorb the liquid and solidify the sewage.
In the electronics industry, super absorbent polymers can also be used as humidity sensors, moisture measurement sensors and water leakage detectors. Highly water-absorbent polymers can be used as heavy metal ion adsorbents and oil-absorbing materials.

1. Product details of water-absorbent resin for diapers. SAP, which has high water retention and good liquid flow rate, is mainly used for the upper layer of the core diaper. Diapers using NR-511 as the upper layer of the diaper core have extremely low reverse osmosis and dryness. .
