The use of radiation technology for wood processing, the current domestic reports less, but foreign literature on this area is very active.Outdoor WPC floor Good grafting and polymer loading can be obtained by using Co60 gamma radiation with various additives to treat the wood. Gamma ray radiation jute fiber, and then make jute and MMA grafting, can greatly increase the intensity of jute.Outdoor wall panel After the treatment of maleic anhydride-impregnated wood with gamma-ray irradiation, the water absorption of the obtained WPC was remarkably reduced, the dimensional stability was greatly improved, and the compressive strength and hardness were greatly improved.



At present, WPC mostly as a non-structural materials, construction and construction applications, the bending performance of bending and bending resistance of the main criteria for load.outdoor composite decking To obtain good physical properties and processing economy, is to hardness, wood content and reduce the density of three to find a balance. When the load rate is lower than 62.5 mm / min,outdoor decking the bending performance is obviously decreased.



The current WPC materials are mainly used in the construction industry, such as building boards, sheet metal panels, doors, windows, staircase handrails, decorative materials, bedding materials, etc .;How to judge WPC floor quality automotive industry, such as door panels, car panels, ceiling materials; Such as the greenhouses stent, trough, etc .; transportation industry, such as highway fence, isolation wall, rail fence, railway sleepers, etc .; warehousing industry, such as material handling with crates,WPC floor quality The largest application of WPC is in such as floor and secondary building materials such high-end products.
