In this paper,the related properties(long-term dimensional stability,adhesion strength,painting film adhering capacity,painting film wearing and consuming value and wood surface hardness) of two plantation-grown hardwoods(Betula alnoides and Castanopsis hystrix),compared with commonly used Quercus mongolia domestically,were investigated. The test on long-term dimensional stability is referred to the method established by New Zealand Forest Research Institute,test on adhesion strength is conducted according to the criteria ASTM D905-89,the test on painting film adhering capacity is referred to the criteria GB/T 1765-1999 and GB/T 1765-1999,and wood surface hardness is referred to JIS Z2117-1963.In the meantime,adhesion strength and painting film adhering capacity are assigned to the corresponding grades according to different criterion based on a series of experimental results. The results show as follows: the adhesion strength,painting film adhering capacity of B. alnoides,C. hystrix and Q. mongolia belong to excellent grade with similar long-term dimensional stability. The total of radial and tangential swelling coefficient of the three species are 0.064%,0.068% and 0.066%,respectively. With regard to painting film wearing and consuming value of the three species,the quality grades are good,middle and good in order. The surface hardness on different wood surfaces of three species is 11.0,7.7 and 13.0 MPa on radial surface,14.2,10.6 and 12.5 MPa on tangential surface,33.0,26.6 and 38.1 MPa on end surface,respectively.
