摘要

熱燙加工是加工材於送材狀態下，以加熱之金屬圓盤或金屬壓板施加壓力於材面，使木材表面因高溫與壓力產生局部塑性變形，造成表層之緻密化，增加加工面光滑度，並可消除由砂磨或切削加工所產生之起毛木理等缺點。木材熱燙加工之目的在簡化家具製造上側面砂光作業及塗裝工程。本研究乃針對不同溫度、壓力（氣缸出力）對橡膠木及中密度纖維板熱燙效果之影響加以探討，其結果歸納如下：1.中密度纖維板之熱燙效果隨熱燙溫度之增加而增加，溫度超過150°C時，表面噴底接者之熱燙效果較未噴底漆者為佳。2.中密度纖維板之表面粗糙度隨熱燙次數之增加而更為改善。3.橡膠木之表面硬度隨熱燙溫度及壓力之增加而增大，與濕潤性有直接關係之接觸角，體溫度及壓力之增加而變大（即濕潤性變劣）。4.橡膠木之表面粗糙度隨熱燙溫度與壓力之增加而減小；表面色差及光澤度隨熱燙溫度典壓力之增加而變大。

The objective of this study is to investigate the effect of the temperature and pressure of hot iron processing on the surface properties of rubber wood and medium density fiberboard (MDF). The surface properties examinedin this study include roughness, hardness, wettability, gloss and color. The experimental results obtained are summaried as follows: 1. The effect of hot ironing on the surface properties of MDF is improved by in. creasing the temperature. When the temperature is above 150°C, the improved effectiveness obtained by pretreating MDF with lacquer sealer is better than that without pretreatment. 2. The surface roughness of MDF decreases by increasing the number of hot iron processmg. 3. The surface hardness and contact angle of rubber wood increase as a function of the temperature and pressure of hot iron processing 4. The surface roughness of rubber wood decreases by increasing the temperature and pressure of hot iron processing , whereas the changes in color and gloss increase by increasing the temperature and pressure of hot iron processing.
