The aim of this study was to evaluate the effect of rosin sizing agent on the
mechanical properties of Styrax tonkinensis wood treated with 1%, 2%, and
4% the mixture of rosin sizing agent and the mixture of rosin sizing agents
and 3% boric acid. The results showed that the use of rosin singing agent
alone or combination with boric acid to impregnate styrax wood has a
certain influence on the mechanical properties of wood. Styrax wood after
being treated by rosin sizing agent alone or in combination with boric acid
has increased the compression strength parallel to grain of wood. In
comparison with untreated controls, the compression strength of wood
samples treated with the mixture of rosin and boric acid increased by
approximately 30%. When the concentration of rosin sizing agent solutions
increased from 1 - 4%, the compression strength tends to increase, but this
increase was not significant. However, the rosin sing agent - boric acid
treatments slightly reduced the modulus of rupture and modulus of
elasticity in bending of the wood. In addition, the increase of rosin sing
agent concentration does not significantly affect the modulus of rupture and
modulus of elasticity in bending of the wood.
