It is widely recognized that, in such cases, the particle diameter of rubber (PB latex or SBR latex) greatly governs the impact resistance and processability of the final products.
Final design scheme is confirmed after economic and technical analyse. Then, axial fan 's stage type, impeller diameter, hub ratio , specific speed and the number of blades are decided.
At last, final drying schedules of small-diameter lumbers of Larch and Cathay poplar were developed according to the result of this research, and Suggestions were given to improve drying quality.
