The Effect of Furfurylation Using Different Processes on Dimensional Stability and Durability of Bamboo Strips
Furfurylation of wood is a very promising modification process,which can produce wood with better moisture resistance,increased dimensional stability,and effective durability resistance to fungi simultaneously.The aim of this work was to evaluate the suitability of the furfurylation process for bamboo strips.For impregnation two different processes were applied.The first process(S represent Soaking process)consists of 36 h of soaking at normal pressure.The second process(V-P represent Vacuum-Pressure process)was more severe and consists of 30 min of vacuum,3 h pressure(0.5 MPa)and 36 h of soaking at normal pressure.Weight percent gain(WPG),equilibrium moisture content(EMC),anti-swelling efficient(ASE),modulus of rupture(MOR),modulus of elasticity(MOE),parallel-to-grain compressive strength(CS)and durability resistance to mould were used to determine the effective of furfurylation of bamboo with different processes.It turned out that two furfurylation processes improved the mechanical properties of bamboo and showed an interesting potential to improve the durability resistance against mould fungi of bamboo.Although the second process(V-P)produced bamboo strips with higher WPG and better durability resistance to mould,the ASE value was negative which revealed the dimensional stability was worse than control bamboo.However,the furfurylated bamboo treated by the first process(S)showed improved dimensional stability.
