Abstract
A method and apparatus for producing a superabsorbent foam is provided. The method includes forming a reaction mixture comprising at least one compound capable of forming a superabsorbent foam, stirring the reaction mixture, applying mechanical waves to the reaction mixture and repeating the stirring and applying a selected number of times thereby forming the superabsorbent foam.
Claims24
Apparatus for forming a superabsorbent foam, the apparatus comprising:
- a reactor having a reaction chamber therein for receiving a reaction mixture comprising at least one compound capable of forming a superabsorbent foam;
- a receiving chamber for receiving said superabsorbent foam formed in said reaction chamber;
- a stirring unit for stirring said reaction mixture, said stirring unit includes a shaft and at least one blade operating to stir said reaction mixture in said reaction chamber;
- a sonication unit for applying mechanical waves selected from sonic waves and ultrasonic waves to said reaction mixture;
- a control unit for repeating the operation of said stirring unit and said sonication unit a selected number of times to form said superabsorbent foam;
- and
- a first piston assembly having at least one piston for displacing said superabsorbent foam formed within said reactor from a first position within said reaction chamber to a second position within said receiving chamber.
