【Abstract】 In this paper biomasses, fiber properties, chemical compositions, sand contents and chip size distribution in complete tree or whole tree are discussed. Investigations have been carried out on fiberboard made from a mixture of whole pine tree in a pilot scale. The results are summarized as follows. Chips from whole pine tree decreased the pulp yield and gave pulps lower drainage time. Both the mechanical and water resistance properties of fiberboard seemed to have been improved with increasing amount of whole pine tree chips except for impact strength which was decreased with whole pine tree chips. But the most serious is the decreased pulp yield causing water pollution.更多还原
