Environmental enhancing adhesion properties of Wood-Plastic Composites by plasma at atmospheric pressure

Abstract

Chemical enhancing adhesion properties of Wood-Plastic Composite (WPC) has been strongly negative affected to human life. The disadvantages of the currently treatment system are low treatment efficiency, costly and unstable due to using combining physics and chemistry methods. In this study, the adhesion wood-plastic composite in line production system using plasma at atmospheric pressure was designed and developed to solve the above disadvantages. The before and after treating, the percentage of area removed of samples were measured by Elcometer 107 Cross Hatch Cutter and ImageJ software for adhesion evolution. Applied power, carrier speed and treatment cycle times were used for analyzing the adhesion efficiency. The results showed that applied power and treatment cycle time are strongly effect to adhesion efficiency. Moreover, carrier speed is also effective. The treatment efficiency leads to higher than 3B standard at applied power 156W, 750mm/min and three treatment times.
