Utilization of recycled poly vinyl chloride (PVC) in combination with wood particles and urea formaldehyde resin as binder to produce multi-layer particle board

摘要

Particle board generally suffers from severe thickness swelling and water absorption which limits its utilisation such as cabinetry, table tops, shelving, wall, floor panel and in humid places such as bathrooms also. To overcome such limitation, addition of recycled PVC into the middle layer of multi layered particle board was investigated. In this study physical and mechanical property of the wood plastic particle board (WPPB) made using Poplar spp. {Poplus deltoides) particles were evaluated. The content of urea formaldehyde resin used as 10 % total weight of the particle board. For Poplar spp. (P. deltoides) particles slenderness ratio was maintained around 160-180 for face particle and around 50-80 for core particle. Addition of PVC was 10, 20,30 and 40 % mixed with core particle to the middle layer. The multi layered WPPB were produced applying press temperature of 150 °C for 7 min of compression cycle at 24 kg/cm~2 and 8 min of curing cycle at 12 kg/cm~2 for the manufacture of WPPB. The boards were tested according to IS: 3087-2005 Gr II.
