    摘要： An extruded product having a foam core is formed by blending powdered cellulose with a base resin and an oxidizer to yield a first mixture. The first mixture is compressed, heated and extruded to form a pelletized compound which is compressed and heated into a homogeneous extrudable mixture. Moisture is extracted from the powdered cellulose at one or more points during the process to achieve a moisture content of less than about two percent. A protective cladding is coaxially extruded around a core of the extrudable mixture to form an elongated product having a foam core at least partially enclosed by the protective cladding.

    摘要： The invention describes a process for the preparation of a natural fiber and thermoplastic composite and the resulting products therefrom. The process includes the steps of mixing the natural fiber and the thermoplastic in a blender with a porosity aid and an interfacial agent to form a mixture; adding the mixture to a heated extruder; compressing the mixture with an extruder screw having a plurality of flight sections, at least one of the flight sections serving as a compression flight section which compresses the mixture by having its flights spaced closer together than other adjacent flight sections, and at least one other vent flight section which allows gaseous reaction products to be removed from the extruder through a vent in the extruder by having its flights spaced farther apart than the compression section, the vent flight section being positioned after the compression flight section; extruding the mixture through an extrusion die as a composite; and shaping the composite in a vacuum calibration device to a desired profile. The process further includes the step of co-extruding a second thermoplastic onto the natural fiber/thermoplastic composite for some applications (e.g., windows, doors and siding).

    摘要： A method of manufacturing a simulated wood product which has not only a texture similar to wood, but also exhibits a pattern similar to the grain of natural wood depending on molding conditions, and such a simulated wood product itself. Specifically, pulverized dust 102 obtained by pulverizing a cellulose material as raw materials is subjected to a trituration process to produce powdery particles 111, 121 having an increased bulk specific gravity, surface particles 112, 122 smaller in size and harder than the powdery particles are fixed to outer circumferential surfaces of the powdery particles to produce fixed particles 110, 120, a resin and a pigment are mixed with the fixed particles, and a resultant mixture is melted to be later or simultaneously molded into the desired shape by extrusion or injection molding.

    摘要： A polymer and wood composite structural members can be manufactured by extruding and injection molding a composition comprising polyvinyl chloride, wood fiber and optionally a concentration of an intentionally added waste stream. Such structural members have strength, workability, fastener retention, resistance to rot and insect attack, and thermal properties sufficient to constitute an advanced composite wood replacement material. The advanced structural member can be used as a component in construction of any structure requiring sized lumber or specifically shaped wood products. In such an application, the structural members can be extruded in the shape of commonly available lumber. The structural members of the invention can also be extruded in complex shapes adapted to the assembly of windows and doors used in both residential and commercial structures. The structural members have a modulus, a coefficient of thermal expansion, a coefficient of elasticity, a compressive strength and other related properties ideal for use as a replacement for either metal or wood, window or door structural components. The preferred structural member is manufactured from a polyvinyl chloride and wood fiber composite that optionally contains an intentionally recycled impurity component. Such components comprise waste materials common in the manufacture of wood doors and windows. We have found that the cooperation between the amount of polymer material, the amount of an oriented wood fiber, and control over water content results in the improved structural properties of the composite structural members of the invention.
