- What is polyacrylamide used for?
- One of the largest uses for polyacrylamide is to flocculate solids in a liquid. This process applies to water treatment, and processes like paper making and screen printing. Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer.
- Is polyacrylamide a powder or liquid?
- Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer. Even though these products are often called 'polyacrylamide', many are actually copolymers of acrylamide and one or more other species, such as an acrylic acid or a salt thereof.
- What is the standard state of polyacrylamide?
- Unless otherwise stated, data refer to materials under standard conditions (25 °C [77 °F], 100 kPa). Polyacrylamide (abbreviated PAM or pAAM) is a polymer with the molecular formula (-CH 2 CHCONH 2 -).
- Can a polyacrylamide emulsion be diluted with water?
- r solutionFundamentalsPolyacrylamide emulsions are not simple concentrated solutions of polymer, so a simple dilution i water is not possible. When preparing a polymer solution from an emulsion, there are two physical phenomena (phase inversion and dissolution) which take place and need specific conditi
