Abstract:

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.
