Processing-wood-Plastic-Composite. When pellets are too large they have a tendency to melt unevenly, create additional friction and settle into a structurally inferior final product. The ideal pellet should be about the size of a small BB and rounded to achieve an ideal surface to volume ratio. These dimensions facilitate drying and help to ensure a smooth flow throughout the production process. Manufacturers working with wood-plastic composites should expect the same shape and

WPCs have many benefits: ?They are true hybrid materials and combine the best properties of both wood and plastics. ?They use low cost and plentiful materials. wood plastic composites? wood-Plastic composites. Plastic composites. A technical review of materials, processes and applications. A technical review of materials, processes and applications. The concept of wood- plastics composites.
The wood and thermoplastics are usually compounded above the melting temperature of the thermoplastic polymers and then further pro- cessed to make various WPC prod- ucts. WPC can be manufactured in a variety of colors, shapes and sizes .. other melt-blending processes. Once the materials are sufficiently mixed, the composite can then be formed into the final shape using forming technologies such as extrusion or injection molding. Forming: Most WPCs are manufactured.
wood components are generally used in sawdust form or small fibers, and typically comprise between 50 and 70 percent of the final wood plastic composite. Maple, oak, and pine are common types of sawdust, and tend to be relatively low-cost to obtain. Because of the high cellulose content from the wood, WPC assumes many of the same characteristics of wood and can be subjected to the same processes, including planning, drilling, and sanding. Nails, screws, and other fasteners

More specifically, WPCs are composites containing a wood component in particle form (wood particles/wood flour) and a polymer matrix. They are used in a
wood plastic composite materials are used wherever wood has traditionally been employed. First and foremost,. WPC is employed as a flooring material. (decking) mainly outdoors, but also indoors. WPC is also used as railing, privacy fencing, exterior wall cladding, furniture and much more. Manufacture. WPC profiles, which are produced in a single or two-stage extrusion process, are the most commonly manufactured form of WPC (figure 1). Single-stage Extrusion: This is a so-called
To this end, wood samples of Pine (Pinus caribaea) and Eucalyptus (Eucalyptus grandis), whose density is compatible with this process, were impregnated with the polymeric monomers styrene and methyl methacrylate, using benzoyl peroxide to process whereby monomers are joined to form a polymer. polymers are widely used in composites as fibers or as the matrix<sup>5</sup>. More information about polymers can be found in the literature indicated<sup>6-8</sup>. 2.3. wood-polymer composites.
The wood material used in wood-polymer composites is either wood flour or wood fibres. The term fibre refers to a single spindle-shaped wood cell, even though it is sometimes used inaccurately to describe wood particles. Individual fibres can be separated from wood using various chemical or mechanical methods familiar from papermaking processes. Fibres have typically high strength and quite high aspect ratios (length-to-diameter ratio, l/d); therefore, their reinforcing potential
additives. wood can be used in various forms, however, it is commonly used in the form of wood flour (fine particles).. wood plastics composites are a new type of material that are beginning to find applications in a wide variety of fields.In this report at first, Important aspects of application related then economic investment and required infrastructure facilities estimated. This research adapted basics and indicators for construction of WPC manufacturing with economic conditions in Iran.
This paper will address the manufacture of wood plastic decking by extrusion, and resulting properties of the wood plastic composite lumber. Topics to be covered include the materials used to manufacture wood plastic composites including thermoplastics, wood form and processing additives, the extrusion processes used to manufacture wpc lumber, and properties and products. As an industry, the manufacture of wood plastic lumber decking is less than 15 years old. It has.
