| titleOfInvention | Continuous method for preparing polyacrylate resins |
| abstract | Abstract of the Disclosure A method and apparatus for continuously manufacturing water absorbing resin. A mixed monomer solution is stored in a storage vessel and a polymerization initiator stored in an initiator storage vessel. The monomer solution is fed by gravity or otherwise through conduit to a lower position (below the liquid surface) of a reaction chamber of a reaction vessel at a rate of, for example, 4 gallons per minute. Simultaneous-ly, the polymerization initiator is fed at a rate of, for example, 0.2 gallons per minute by gravity or otherwise through a conduit to an opposite side of the reaction chamber, again at a lower portion (below a continuously maintained liquid level) to begin polymerization. The reaction product forms from an upper surface of the reactant mixture (mixed monomer solution plus initiator) and travels upwardly through a truncated frustoconical cone shaped upper portion of the reaction chamber as a solid resin. The reaction product is sufficiently rigid to proceed upwardly from an upper annular edge of the upper reaction chamber portion until the resin meets an upper con-veyor belt. The upper conveyor belt, driven in a counter-clockwise direction, pushes the mass of reaction product onto a lower conveyor belt on which the resin cures and dries without the addition of external heat. |
