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。724Please respect copyright.PENANAgKYApHu7Nt

(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。724Please respect copyright.PENANAaz9MCaAAIi

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。724Please respect copyright.PENANAxOo8VUFMZZ

(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。724Please respect copyright.PENANAMLXw49KTZh

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。724Please respect copyright.PENANAHmTKQiOFTI

(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!724Please respect copyright.PENANAMWOHWmGjtb
