摘　　要：研究微米木纤维模压制品形成的专用模压设备,阐述试验方法,介绍初步的模压工艺。根据其方法可制备密度达1.30g·cm-3、握钉力达2450N、孔深50mm以上的压制木零件,超过现有纤维或刨花制品的性能。本文提出的微米木纤维模压制品工艺方法,可以制备具有超高密度和超高强度的异型曲面零件,一次成型,提高原料利用率,并简化异型曲面零件加工工序。将细胞裂解理论、微米切削技术转化到工程应用,有效利用了废劣材、次小薪材,通过细胞重组和模压成型,提高了木材出材率。文中给出试验的初步工艺参数是经过多次试验获得的宝贵经验,对有志于该方向的产品开发将起到重要的借鉴和推动作用。Micron wood fiber mould product based on cell break theory is a new kind of man made high strength wood product. It is mainly used on decorate parts of top grade cars and furniture. It has advantages as keeping original wood color, good surface luster and high mechanical quality. This paper studied the special mould pressing equipment of forming micron wood fiber mould product, explained the experimental method and introduced the primary mould technology. According to the method, pressing wood parts are able to be manufactured, which density is 1.30 g·cm^-3 , nail-holding strength is 2 450 N, depth of hole is more than 50 mm. Its capability is better than the fiber and flake products. The technological technique put forward by this paper is able to be used to make grotesque and curve parts having super density and super strength. The molding is done once. The using ratio of material is improved. The technological process of grotesque and curve parts is simplified. The cell break theory and micron cutting technology are transformed into engineering application. The waste, bad, small and inferior wood or firewood are taken into use effectively. The yield ratio of wood is improved by reconstituted technology and molding. The primary experimental technological parameters proposed by this paper are rare experience from plenty of experiments. The product exploitation can use it for reference and will be promoted greatly.
