Effect of Rotary Drying System for Processing Bamboo Strands on the Properties of Bamboo Oriented Strand Board
This paper takes moso bamboo strands as raw material and gets them dried with rotary drying system to explore the impact of drying temperature and drying time on the drying rate and the appearance of bamboo strands,as well as the influence of different drying processes on the mechanical properties of bamboo oriented strand board(BOSB).The results show that prolonging the drying time could not only discolor bamboo strands and increase the degree of warping and tearing,but also make the static bending strength of the produced BOSB significantly decreased,while the drying time of 30 min decreases 47.77%of the static bending strength compared with the drying time of 10 min;increasing the drying temperature has no direct connection with the regularity of change in the color and appearance of bamboo strands,but it can promote the drying rates slightly,and leads to smaller decrease of the BOSB properties than the extension of drying time.In view of the performance and the capacity efficiency of products,it is suggested that in the actual BOSB production,if the rotary drying system is used,the drying process should be controlled at a drying temperature of about 210℃and a drying time of about 10 min.
