ESTUDO E DESENVOLVIMENTO DO COMPÓSITO PVC/WOOD (WPC)

Abstract

This work has as objective, in addition to presenting the detailed study related to the process and material development, also to develop it, carry out tests and comparisons, and with that, to evaluate the technical feasibility of obtaining PVC lignocellulosic composites, and thus, improve products already manufactured and implement new products, aiming at sustainability and avoiding the loss material. PVC/wood, also known as WPC, is a German technology material that, as the name says, is made from a mixture of wood and PVC, using wood residue as reinforcing load. The material unites the better of the two compounds, using the reinforcement of wood fibers to make the moldable and waterproof PVC structure more resistant to mechanical stress. Its production line is simple and requires little machinery to generate the final product, also consumes little raw material, most of which is reused in other

ways such as plastic recycling and the reuse of wood disposal, being a material of high eco- sustainable value. The analytical study to develop PVC/wood contributes to the better use of

wood dust, this material, which is of paramount importance to the process and which today does not have a proper end. For the development of the WPC material line, necessary to use machinery and materials, however, to carry out the initial tests, it is possible to adapt the process due to the smaller amount of products used. The reported experiment demonstrated that when performed according to the detailed procedure, can be efficient, even if the process is adapted for testing only. The results obtained in this study indicate that the process is efficient and can be a good alternative for the reuse of wood dust. It can also be notice that PVC/wood manages to replace and be superior to wood in almost every aspect.
