Abstract To improve the mechanical properties of fast-growing Chinese fir (Cunnighamia lanceolate), expand its range of
application, increase its value, and avoid the environmental pollution caused by impregnation with synthetic
resin, Chinese fir was impregnated with a shellac solution. Since the shellac solution was difficult to penetrate into
fast-growing Chinese fir, so microwave pretreatment was used to irradiate the wood to improve the permeability.
This study investigated the effects of four factors, including the content of moisture in the wood before it was
microwaved, the chamber pressure of microwave, the time of microwaving and the vacuum impregnation on
the mechanical properties… More >
