Study on the Effects of Microwave Pretreatment on the Fire Retardant Permeability of Fast-Growing Wood

Abstract:

The paper preheated poplar and Chinese fir with microwave before dipping into fire retardant solution with the purpose of improving their permeability. The test results showed that microwave increased the routs for liquid which proved to be a feasible way to facilitate fire retardant solution to enter into wood. Fire retardant loading dosage (FRLD) and implantation depth (ID) increased for both poplar and Chinese fir. Fire retardant properties such as oxygen index (OI), mass loss rate (MLR) and flame combustion time (FCT) increased and can meet the fire retardant wood requirements defined by standard of GA/T 42.1-92.
