科普專欄–薯不揀單 - 三十秒科學–國王的木板

木材是非常堅韌的優良建築材料，強硬要挑剔的話，就是透光度不足，造就散熱不足的問題等等。924Please respect copyright.ＰＥＮＡＮＡMB3PR2n0XE

（圖2）木材之所以呈啡色及擁有堅硬的特性，全因其內部結構的木質素所致。924Please respect copyright.ＰＥＮＡＮＡkhSfV8KyxG

現時有一些方法為了製作透明顏色的木材，不惜利用強酸等化學物破壞木質素，但壞處就是放棄了木質素所帶來的堅韌性質。924Please respect copyright.ＰＥＮＡＮＡPPeSRu7XQt

（圖3）現時的最新方法，就是在木板上塗上雙氧水及利用紫外光的照射，針對性對木質素的色素結構做成破壞，但基於只破壞色素結構，造就堅韌性質的結構組織並不受到任何的大影響。924Please respect copyright.ＰＥＮＡＮＡGisP4EGdG1

之後再注入合適條件的環氧樹脂 (Epoxy)，便可成為堅硬的透明木板。924Please respect copyright.ＰＥＮＡＮＡiGZwkC3GcZ

（圖4）只要掌握落雙氧水的位置，不但可使整塊木板透明化，甚至在木版上畫公仔圖案也沒有問題!924Please respect copyright.ＰＥＮＡＮＡkFPMlTKhwE
