做(zuo)激光(guang)刀模所用的(de)膠合木板都有哪些？

膠(jiao)合(he)木(mu)板是原木(mu)浸水后通(tong)過卷刨切(qie)割成按尺寸要求的連續薄(bo)片板，用機器降(jiang)低水分(fen)到適(shi)當標準(zhun)值，再用尿素甲(jia)醛膠(jiao)水以十字交叉(cha)方(fang)式多(duo)層粘(zhan)結而成的板材。粘(zhan)結前的薄(bo)片板應按標準(zhun)分(fen)好等級且進行過預壓處(chu)理。

做激光刀模常用的有(you)：國產楊木膠合(he)(he)(he)板，國產樺木膠合(he)(he)(he)板，進口芬(fen)蘭(lan)膠合(he)(he)(he)板等(deng)。
