Hydrated water gel, or water beads. Water crystal gel or water beads or gel beads is any gel which absorbs and contains a large amount of water.Water gel is usually in spherical form and composed of a water-absorbing superabsorbent polymer (SAP, also known as slush powder in dry form) such as a polyacrylamide (frequently sodium polyacrylate).
Sodium polyacrylate has also been studied for utilization in many applications such as nanofiltration of water to absorb water and concentrate the liquid with microbes. [11] Also, it is used for eco-engineering as a water-retaining agent in rocky slopes for increasing moisture availability in the soil.
Common hydrogel agriculture's ingredient is potassium polyacrylate or sodium polyacrylate. As a superabsorbent material, it can absorb plenty of water and turn water to gel to store water. Hydrogel agriculture technology uses insoluble gel-forming polymers to improve the water-holding properties of different soils, such as clays and sandy loams.
Superabsorbent polymers are now commonly made from the polymerization of acrylic acid blended with sodium hydroxide in the presence of an initiator to form a poly-acrylic acid sodium salt (sometimes referred to as sodium polyacrylate). This polymer is the most common type of SAP made in the world today.
Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH. In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers (such as polyethylene oxide, poly-N-vinyl pyrrolidone, polyacrylamide, and some cellulose ethers) and form hydrogen-bonded interpolymer complexes.

Polyacrylate emulsion, water-borne coating, are used as binder for outdoor and indoor "latex" house paints.; Acrylic paints as artist paints.; Acrylic fibre.; Sodium polyacrylate water-soluble thickeners, a polymer for the production of the Superabsorbent polymer (SAP) used in disposable diapers due to its high absorbency per unit mass.
Water gel may refer to: Hydrogel, a soft water-rich polymer gel; Water crystal gel, a water-absorbing polymer; Water gel explosive, a fuel-sensitized explosive mixture
Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2-).It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated.
