    摘要： Water-absorbing, expanded, crosslinked polymers obtainable by (I) foaming a polymerizable aqueous mixture which comprises (a) monoethylenically unsaturated monomers which contain acidic groups and are optionally neutralized, (b) optionally other monoethylenically unsaturated monomers, (c) crosslinkers, (d) initiators, (e) 0.1-20% by weight of at least one surfactant, (f) optionally at least one solubilizer and (g) optionally thickeners, foam stabilizers, polymerization regulators, fillers and/or cell nucleating agents, where the foaming takes place by dissolving a gas which is inert to free radicals under a pressure of 2-400 bar in the polymerizable aqueous mixture, and then decompressing the latter to atmospheric pressure, and (II) polymerizing the foamed mixture to form an expanded hydrogel and, where appropriate, adjusting the water content of the expanded polymer to 1-60% by weight, process for preparing the water-absorbing, expanded, crosslinked polymers and use of these polymers in sanitary articles employed for absorbing body fluids, in dressing material for covering wounds, as sealing material, as soil improver, as soil substitute and as packaging material.

    摘要： An application system for applying a solid particle includes an injector housing having a material inlet, a gas inlet, and a material outlet, and an occluder moveably disposed within the injector housing between the gas inlet and the material outlet. The injector housing and the occluder define there between at least one adjustable aperture downstream of the material inlet and in fluid communication with the gas inlet and the material outlet. The aperture has a first open area with the occluder in a first position and a second open area with the occluder in a second position, the second open area being different than the first open area. The system also includes a nozzle having a nozzle inlet coupled to the material outlet and a nozzle outlet, the inlet having a circular cross-section and the outlet having a rectangular cross-section.
