Title: INVESTIGATION ON PLASMA-AIDED FLAME RETARDATION OF MEX-ICAN WHITE CEDAR (CUPRESSUS LUSITANICA) WOOD BY THERMAL ANALYSIS
Keywords: dielectric barrier discharge, plasma aided capillary impregnation, flame retardants, Mexican white cedar (Cupressus Lusitanica) wood
Abstract: The plasma aided flame retardation of wood, wooden products and cellulosic fibrous materials has been conceived and developed as a result of plasma aided process of capillary impregnation. The plasma-chemical surface pre-treatment substantially alters its electrical, chemical and capillary activity, thus improving some impregnation process basic characteristics, such as penetration depth, solution spreading and adsorption speed, adsorbed solution capacity. Thermal analysis has been used to reveal the impact of a new phosphor and nitrogen containing flame re-tardant and plasma-aided capillary impregnation on flame retardation of Mexican white cedar wood. This study has been developed as part of a large investigation on plasma activated (functionalized) wood surface and flame retardant treated wood.
