Title: Plasma-aided flame retardation of mahogany caoba (swietenia macrophylla) wood
Keywords: Dielectric barrier discharge surface treatment, plasma-aided capillary impregnation, flame retardation of wood and wooden products, thermal analysis
Abstract: The plasma aided flame retardation of wood, wooden products and cellulosic fibrous materials has been conceived and devel-oped as a result of plasma aided process of capillary impregnation. The plasma-chemical surface pre-treatment substantially alters its elec-trical, 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 (TGA, DTA and DSC) has been used to reveal the impact of a new phosphor and nitrogen containing flame retardant and plasma-aided capillary impregnation on plasma-aided flame retardation of Caoba or Mahogany (Swietenia macrophylla) wood. This study has been developed as part of a large research on plasma-chemically acti-vated wood surface and flame retardant treated tropical wood.
