現在常見的建筑膠合板是將(jiang)木(mu)材(cai)(cai)切片(pian)切割成(cheng)單板(ban)(ban)或將(jiang)木(mu)方刨成(cheng)單板(ban)(ban)，用(yong)粘(zhan)合(he)劑粘(zhan)合(he)而成(cheng)的三(san)層或多層板(ban)(ban)狀材(cai)(cai)料(liao)。一(yi)般情(qing)況下(xia)采用(yong)奇(qi)數號單板(ban)(ban)，相鄰(lin)單板(ban)(ban)的纖(xian)維方向互(hu)相膠合(he)成(cheng)直(zhi)線。

為(wei)了(le)盡(jin)可(ke)(ke)能提高天然木材的(de)(de)(de)各(ge)向(xiang)異性(xing)(xing)性(xing)(xing)能，使建筑(zhu)膠(jiao)合板(ban)具有(you)均(jun)勻的(de)(de)(de)特性(xing)(xing)和穩定的(de)(de)(de)形狀，建筑(zhu)膠(jiao)合板(ban)的(de)(de)(de)結構應遵循一些關鍵的(de)(de)(de)原(yuan)則(ze)，一是對(dui)(dui)稱(cheng)(cheng)，二是相(xiang)鄰層的(de)(de)(de)單(dan)板(ban)纖(xian)維相(xiang)互之間(jian)是直的(de)(de)(de)。對(dui)(dui)稱(cheng)(cheng)原(yuan)理要(yao)求建筑(zhu)膠(jiao)合板(ban)對(dui)(dui)稱(cheng)(cheng)中心面(mian)兩端的(de)(de)(de)單(dan)板(ban)應相(xiang)互對(dui)(dui)稱(cheng)(cheng)，不考慮木材性(xing)(xing)質、單(dan)板(ban)厚(hou)度(du)、層數、纖(xian)維方(fang)向(xiang)、含水(shui)率等。在同一建筑(zhu)膠(jiao)合板(ban)中，也(ye)可(ke)(ke)以(yi)使用單(dan)一樹(shu)種(zhong)和厚(hou)度(du)的(de)(de)(de)單(dan)板(ban)，但對(dui)(dui)稱(cheng)(cheng)中心面(mian)兩端的(de)(de)(de)任意兩塊對(dui)(dui)稱(cheng)(cheng)單(dan)板(ban)應具有(you)相(xiang)同的(de)(de)(de)樹(shu)種(zhong)和厚(hou)度(du)，面(mian)板(ban)和背(bei)板(ban)不應允許是同一樹(shu)種(zhong)。

大家應該都知道建(jian)(jian)筑(zhu)膠合(he)板(ban)(ban)(ban)是(shi)我們生(sheng)活中(zhong)常見的建(jian)(jian)筑(zhu)裝(zhuang)飾材料(liao)，但是(shi)市場上的產品很(hen)多。如果要(yao)用合(he)格的產品，就需要(yao)區(qu)分產品的質量。為(wei)了使(shi)建(jian)(jian)筑(zhu)膠合(he)板(ban)(ban)(ban)的結(jie)構(gou)符合(he)上述兩個(ge)基本原則，其層數(shu)應為(wei)奇數(shu)層，所以建(jian)(jian)筑(zhu)膠合(he)板(ban)(ban)(ban)一般(ban)做成三層、五層、七層等奇數(shu)層。表層單(dan)(dan)板(ban)(ban)(ban)叫(jiao)(jiao)表層板(ban)(ban)(ban)，內層單(dan)(dan)板(ban)(ban)(ban)叫(jiao)(jiao)芯(xin)板(ban)(ban)(ban)，正面(mian)單(dan)(dan)板(ban)(ban)(ban)叫(jiao)(jiao)面(mian)板(ban)(ban)(ban)，背面(mian)單(dan)(dan)板(ban)(ban)(ban)叫(jiao)(jiao)背板(ban)(ban)(ban)。在芯(xin)板(ban)(ban)(ban)中(zhong)，平行于面(mian)板(ban)(ban)(ban)的纖(xian)維方向稱為(wei)長芯(xin)板(ban)(ban)(ban)或中(zhong)間(jian)板(ban)(ban)(ban)。當形成空腔(qiang)底板(ban)(ban)(ban)時，面(mian)板(ban)(ban)(ban)和背板(ban)(ban)(ban)必須朝外。

為了充分利(li)用(yong)(yong)(yong)森林資(zi)源(yuan)發(fa)展建(jian)(jian)筑(zhu)(zhu)膠合(he)板(ban)生(sheng)產，充分利(li)用(yong)(yong)(yong)材料(liao)，我(wo)國新制定的國家(jia)標準(報批草案)將建(jian)(jian)筑(zhu)(zhu)膠合(he)板(ban)分為飾(shi)(shi)面建(jian)(jian)筑(zhu)(zhu)膠合(he)板(ban)(用(yong)(yong)(yong)于(yu)家(jia)具、縫(feng)紉(ren)機臺(tai)板(ban)和(he)各種表(biao)面需要涂透(tou)明漆的電器外殼)、裝(zhuang)(zhuang)飾(shi)(shi)建(jian)(jian)筑(zhu)(zhu)膠合(he)板(ban)(用(yong)(yong)(yong)作建(jian)(jian)筑(zhu)(zhu)、家(jia)具、車輛和(he)船舶的裝(zhuang)(zhuang)飾(shi)(shi)材料(liao))、通用(yong)(yong)(yong)建(jian)(jian)筑(zhu)(zhu)膠合(he)板(ban)(適用(yong)(yong)(yong)于(yu)包裝(zhuang)(zhuang)、內襯等用(yong)(yong)(yong)途)和(he)單板(ban)。
