木材表面的热平整技术

本文介绍了热平整技术的理论基础和滚筒热平整技术。采用热平整和辊压的方法 ,木材受热后表面的绒毛状纤维被塑化而固定 ,木材表面变得密实和光亮 ,且没有粉尘 ,有望替代现在的砂光工序。文章还介绍了在电加热平整中 ,把平整工具置于锯切工具后 ,利用锯切工序后产生的切削热平整家具的加工表面和侧面。试验发现高频机械振动和超声波平整不同材料的效果良好 ,因其具有宽广的频域和功率的调整量范围 ,可望广泛应用于多种场合

Hot-leveling Technology for Wood Surface

Hot leveling technology and its theory foundation were introduced as the new approach to replace the traditional sanding process. The application of hot teveling and roller pressing could make the heated fine hair shape wood fiber molded and fixed on the timber surface and thus the wood surface would become dense, bright and clean. Wood surface could be leveled with the heat generated from sawing by setting up the hot leveling tool behind the cutting tool. This paper also pointed out that both high frequency mechanical vibration and ultrasonic leveling had good effects for various materials, and could be applied in many occasions because of the flexible frequency and power adjustment range.
