三十秒科學–國王的木板
No Plagiarism!qrZRxb3mAn5prZAOCtGvposted on PＥNAＮＡ

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。1102Please respect copyright.ＰＥＮＡＮＡAn45BBynuE

（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。1102Please respect copyright.ＰＥＮＡＮＡEvpfX5AsMf
1102Please respect copyright.ＰＥＮＡＮＡBSKV3GBlMF
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。1102Please respect copyright.ＰＥＮＡＮＡ3qaQQttoJp
1102Please respect copyright.ＰＥＮＡＮＡWrXHISafb3
（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。1102Please respect copyright.ＰＥＮＡＮＡfY7CUFLSHv

1102Please respect copyright.ＰＥＮＡＮＡk8WsUnD1Dl
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。1102Please respect copyright.ＰＥＮＡＮＡ8CIzP5rfTz

（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!1102Please respect copyright.ＰＥＮＡＮＡom2pEgplz6
