    • In a process for producing mouldings, in particular particle boards, at least one binding agent is mixed with a least one fine-particle basic material extruded at high temperature and pressure. The basic material has, or is brought to, a total content of 6 to 25 wt.%. It is extruded, together with at least one biopolymer, preferably a binding agent containing starch which can be converted to molten and/or gel form at least at the extrusion temperature and pressure, and the fine-particle material. Immediately after extrusion, the pressure is relieved by spontaneous expansion. The device for implementing the process comprises extrusion machines (2, 20) for starting components in lump form. These machines have an extrusion nozzle (26, 260) and an upstream processing region (204) where the basic material to be processed is partially pressure relieved by internal partial expansion. The extruded mouldings have a compact surface and a basic material in which particles of a fine-particle fibrous material are distributed throughout a matrix containing numerous minute voids. The fraction of starch-containing matrix is equal to 5 to 85 wt.%.
    • 在制造模制品,特别是刨花板的方法中,将至少一种粘合剂与在高温和高压下挤出的至少一种细颗粒基材混合。 基本材料具有或被带到总含量为6至25重量%。 与至少一种生物聚合物一起挤出,优选含有至少在挤出温度和压力下可转化成熔融和/或凝胶形式的淀粉的结合剂和细颗粒材料。 挤出后立即通过自发膨胀释放压力。 用于实施该方法的装置包括用于以块形式启动部件的挤出机(2,20)。 这些机器具有挤出喷嘴(26,260)和上游处理区域(204),其中待处理的基础材料通过内部部分膨胀部分地被减压。 挤出的模制品具有紧凑的表面和基本材料,其中细颗粒纤维材料的颗粒分布在包含许多微小空隙的基质中。 含淀粉基质的比例等于5至85重量%。
