软化处理对杨木刨切单板性能的影响
Effect of softening treatment on the performance of sliced poplar veneer
摘要
Abstract
Sliced poplar veneer was softened with chemical agents to prepare pencil slat.25％ ethylenediamine,25％ ammonia,10％ NaOH solution and 25％ acetic acid solution were chosen as the agents.Properties of the treated veneer,including density,hardness and modulus of elasticity (MOE),were tested and compared with the untreated.The results indicated that the agent type,softening time,softening temperature and the pressure had certain impact on mechanical properties of the veneer.The optimum softening parameters were:softening agent 25％ ammonia,temperature 60℃,time 50min,pressure 0.6 MPa.Microstructure study showed that poplar cell wall was wetted and deformed after the treatment,causing vessel damage and weakening the cell wall' s frame function.关键词
