| 实木复合门的内框架采用内应力小的松木或杉木（松木要比杉木高档的多），制成框架前都要经过烘干处理，使木材的含水率与当地的平衡含水率（木材吸收和蒸发水分的速度相等时的含水率）相当，这样在制成的门门体不易变形，也不存在接口开裂、色差等缺点。 The inner frame of the solid wood composite door is made of pine or fir with small internal stress (the pine is much higher than the FIR). Before the frame is made, it must be dried to make the moisture content of the wood equal to the local equilibrium moisture content (the moisture content when the speed of wood absorbing and evaporating moisture is equal), so that the door body is not easy to deform, and there are no defects such as interface cracking and color difference 。 |
