Superabsorbent polymer: Polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass. [5] Notes: The liquid absorbed can be water or an organic liquid. The swelling ratio of a superabsorbent polymer can reach the order of 1000:1. Superabsorbent polymers for water are frequently polyelectrolytes.
Superabsorbent polymers can be used to release phosphate fertiliser slowly, by making an ester bond between polyvinyl alcohol and phosphoric acid. A polymer/clay superabsorbent composite material made by attaching acrylamide to finely powdered attapulgite (a fuller's earth clay) shows promise for its excellent water retention and low cost ...
A home pasta-making machine is a popular multi-purpose tool for polymer clay artists. It is used to create sheets of uniform thickness, to mix colors or create variegated sheets, and to condition (soften) the clay. [1] Polymer clay generally needs to be conditioned before use.
Quick clay, known as Leda Clay in Canada, is a water-saturated gel, which in its solid form resembles highly sensitive clay. This clay has a tendency to change from a relatively stiff condition to a liquid mass when it is disturbed. This gradual change in appearance from solid to liquid is a process known as spontaneous liquefaction.
Expandable water toys (also grow-in-water toys or grow monsters) are novelty items made from a superabsorbent polymer. They are toys that expand after putting them into water for anything from a few hours up to several days, depending on size. They shrink in saltwater or when exposed to air.
The clay particles are only weakly bound to each other, so various cations or polymers can be bound within the interlayer space. Biopolymers have been shown to strengthen soils both by cohesion with clay particles to form polymer-clay matrices and by promoting the aggregation of coarser soil particles with each other within the polymer-clay matrix.
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).
This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte [2] with negatively charged carboxylic groups in the main chain. It is a polymer made up of chains of acrylate compounds.
