Wood plastic composite in India
Analysis of wood-plastic composite materials, technology and economy (India)
Wood-plastic composite material is processed by the wood flour / wood fiber and plastic mixed, not only has the processing characteristics of conventional plastics, but also has the advantages of wood and plastic. From the point of view of the prospects for international manufacturing, India has missed an opportunity to the development of high-tech manufacturing, is now determined to improve the ability of high-tech manufacturing. Wood processing industry will generate a lot of residue and the community will also have a lot of waste plastics, which are not being put to good use. The production of wood-plastic composites will make the Indian manufacturers to enter the high-tech manufacturing, and the use of these raw materials to produce environmentally friendly products.
This study consists of two parts: analysis of wood-plastic composite technology and the economy (India). The technical part of the main wood-plastic composite materials, raw materials, processes, and equipment needed. Economic analysis of the market prospects of the wood-plastic composite materials and using locally available raw materials from the processing of wood-plastic composite flooring as the trend in India. Technical analysis, we review a variety of literature, factory visits, face to face communication with different scholars or researchers, as well as to participate in the extrusion tests, a comprehensive understanding of the requirements for raw materials in wood-plastic composite materials and different application areas the different formulations. On the basis of the above analysis, it is envisaged that investment in India to produce wood-plastic composite materials.
Economic analysis is mainly based on the basic concepts of economics such as profit and loss, personnel planning, risk forecasting, balance of payments, equipment costs, working capital requirements, depreciation, the key investment, the initial capital requirements. Based on the above research, the following conclusions: wood-plastic composite materials, cellulose-based fillers, such as wood flour, sawdust, rice husks are natural materials, they contain cellulose, hemicellulose, and lignin. The wood flour is milled from a thin powder. Wood flour in wood-plastic composite materials are normally used for the mesh size of 400μm. The mechanical properties of polyethylene, polypropylene, polyvinyl chloride, acrylonitrile – butadiene – styrene and nylon good, but the high-density polyethylene is the most common plastic raw materials in the wood plastic composite outdoor flooring. Coupling agent can improve the compatibility of the cellulose fibers and polymer matrix, contribute to the dispersion of fibers, to improve the mobility of the hot melt material, and mechanical properties of wood-plastic composites, wood-plastic composites production The most important additives.
Extrusion is the most common link in the production process of wood-plastic composites extrusion can be produced with high dimensional accuracy, high stability of the product. For most of the high demand applications, the new wood-plastic composite material is a high-tech products. Wood-plastic composites production gross margin of 29.66%, net profit of 13%. The plant can generally be 2.5 to 3 years to recover investment costs. Put into operation the most important investment in the plant. Listed in the economic analysis of investment, investment in plant and design fees, a total of $ 260,000. When using high-density polyethylene material, wood-plastic composite materials, raw material prices for 915 U.S. dollars / ton. Expected in 2011, the market share of wood-plastic composite materials will grow to 30%. Therefore, for Indian manufacturers, it is now the best time to begin the production of wood-plastic composites.
