    • Zum Herstellen von Schwammgummi-Formteilen, beispielsweise Kugeln, Bälle, Scheiben Platten, Zylinder oder Profistücke, wird vorgeschlagen, dass nur die Aussenschicht (4) des Formteils aus Schwammgummi besteht. Hierzu wird in einer Giessform (1) mit einem auf die Aussenabmessungen des Formteils abgestimmten Hohlraum (2) zunächst ein massiver oder hohler Innenkern (3) aus Gummi oder Kunststoffmaterial positioniert. Anschliessend wird in einen schalenförmigen Zwischenraum (4) zwischen dem Innenkern (3) und der Innenwand (2a) des Hohlraums (2) der Giessform (1) eine Mischung aus einer Gummimasse und einem Treibmittel eingefüllt wird. Nach erfolgtem Einfüllen wird die Giessform (1) auf eine Temperatur erwärmt, bei welcher das Treibmittel in ein Treibgas umgewandelt wird, welches die Gummimasse aufschäumt, und bei welcher die schaumförmige Gummimasse zu einem offenporigen Gummi vulkanisiert wird. Das fertige, vulkanisierte Formteil wird abschliessend aus der Giessform (1) entformt und eine vorhandene Aussenhaut ggfs. von dem Formteil entfernt.

    • This disclosure covers methods of use and manufacture, and apparatuses (240, 250) for dispensing, and compositions of durable, water-dispersible or water-soluble polymer foams (215). Durable water-dispersible foam is soluble in aqueous solutions after curing, does not collapse into a film when dry after curing, and does not require hot extrusion in order to form foam. Durable water-dispersible foams may contain additives and fillers. Durable water-dispersible foams may be applied directly to objects before, during, and/or after curing. For example, durable water-dispersible foams may be sprayed directly onto plants, fruits, vegetables, and other water-resistant objects (220) in order to provide temporary insulation, or for protection during shipping and handling. When the durable water-dispersible foam is no longer needed, it is simply rinsed away with water. Durable water-dispersible foam may also be used as a seed-sowing medium, fire fighting foam, erosion control, modeling material, mold-making material, molded material, and as a frost-protection barrier for plants.
    • 本公开涉及使用和制造方法,以及用于分配的装置(240,250)和耐久的水分散性或水溶性聚合物泡沫(215)的组合物。 耐用的水分散性泡沫在固化后可溶于水溶液,固化后不干燥时不会塌陷,并且不需要热挤压以形成泡沫。 耐用的水分散泡沫可能含有添加剂和填料。 耐久的水分散泡沫可以在固化前,固化期间和/或之后直接施用于物体。 例如,耐用的水分散泡沫可以直接喷洒到植物,水果,蔬菜和其他防水物体上(220),以提供临时隔热,或在运输和处理过程中进行保护。 当不再需要耐用的水分散泡沫时,只需用水冲洗即可。 耐用的水分散泡沫也可用作种子播种介质,消防泡沫,侵蚀控制,造型材料,模具制造材料,模制材料,以及作为植物的防冻屏障。

    • A method and an apparatus for manufacturing panel bodies of plastic material, wherein the plastic material is injected into a mould cavity (59) of a mould for the filtering thereof. After the injection of the plastic material, the cavity is caused to expand from a first volume (V1) to a second, larger volume (V2), whilst the plastic material expands, the plastic material having added thereto a drive means, e.g., a foaming agent or a blowing agent. The moulded panel body is then removed from the cavity of the mould. Prior to the injection of the plastic material, reinforcing material (60) may optionally be placed in the mould in recessed portions (60’) of the first volume of the mould cavity. This reinforcing material may be held up at some points by pushers (21) projecting up through the respective bottoms of said recessed portions (60’) until the recessed portions have been filled with plastic material to surround the reinforcing material. The pushers are withdrawn from the recessed portions and from support of the reinforcing material as the mould cavity (59) expands to its second volume.
    • 一种用于制造塑料材料的面板体的方法和装置,其中将塑料材料注入模具的模腔(59)以进行过滤。 在注塑塑料材料之后,使空腔从第一容积(V1)膨胀到第二较大体积(V2),同时塑料材料膨胀,塑料材料添加了驱动装置,例如 发泡剂或发泡剂。 然后将模制的面板主体从模具的空腔中取出。 在注射塑料材料之前,增强材料(60)可以任选地在模具的第一体积的凹部(60')中放置在模具中。 这种增强材料可以通过从所述凹部(60')的各个底部向上突出的推动器(21)在某些点被保持,直到凹陷部分填充有塑料材料以包围增强材料。 当模腔(59)膨胀到其第二体积时,推动器从凹部和从增强材料的支撑件中取出。
