建筑膠合板是一種三層(ceng)或(huo)多(duo)層(ceng)的(de)板(ban)狀材料(liao)，是將木材紡成單(dan)板(ban)或(huo)刨成單(dan)板(ban)，然后用(yong)膠粘劑膠合而成。通常采用(yong)奇數號單(dan)板(ban)，相鄰單(dan)板(ban)的(de)纖維方向互相垂直膠合。

建(jian)(jian)筑(zhu)膠(jiao)(jiao)合(he)(he)(he)(he)板(ban)(ban)是一種三層(ceng)或(huo)多層(ceng)的板(ban)(ban)狀材(cai)料(liao)，它是將(jiang)木(mu)質(zhi)(zhi)型(xing)材(cai)切割成(cheng)單(dan)(dan)板(ban)(ban)或(huo)將(jiang)木(mu)質(zhi)(zhi)型(xing)材(cai)刨成(cheng)薄木(mu)，然后(hou)用(yong)粘(zhan)(zhan)合(he)(he)(he)(he)劑(ji)粘(zhan)(zhan)合(he)(he)(he)(he)而(er)成(cheng)。通常(chang)采用(yong)奇數號單(dan)(dan)板(ban)(ban)，相鄰單(dan)(dan)板(ban)(ban)的纖維方向互相垂直(zhi)膠(jiao)(jiao)合(he)(he)(he)(he)。膠(jiao)(jiao)建(jian)(jian)筑(zhu)膠(jiao)(jiao)合(he)(he)(he)(he)板(ban)(ban)的一般(ban)長寬規格(ge)(ge)為1220×2440毫米，厚度規格(ge)(ge)一般(ban)為3、5、9、12、15、18毫米等。其他(ta)規格(ge)(ge)的建(jian)(jian)筑(zhu)膠(jiao)(jiao)合(he)(he)(he)(he)板(ban)(ban)都(dou)是小尺(chi)寸膠(jiao)(jiao)合(he)(he)(he)(he)板(ban)(ban)，不常(chang)用(yong)于裝(zhuang)飾。多層(ceng)建(jian)(jian)筑(zhu)膠(jiao)(jiao)合(he)(he)(he)(he)板(ban)(ban)是指(zhi)7層(ceng)和9層(ceng)以(yi)上，主要用(yong)于建(jian)(jian)筑(zhu)和車輛。了解建(jian)(jian)筑(zhu)膠(jiao)(jiao)合(he)(he)(he)(he)板(ban)(ban)的規格(ge)(ge)和尺(chi)寸非常(chang)重要。消費者可(ke)以(yi)根據室(shi)內裝(zhuang)修的面積要求(qiu)合(he)(he)(he)(he)理(li)計算所需的材(cai)料(liao)。三夾(jia)板(ban)(ban)的地方不能(neng)用(yong)五夾(jia)板(ban)(ban)，以(yi)免盲目(mu)購買(mai)材(cai)料(liao)造成(cheng)不必要的浪費。

建筑(zhu)膠(jiao)合(he)(he)板(ban)(ban)是(shi)由一(yi)些很(hen)薄的(de)木片做(zuo)成的(de)，偶爾會有(you)(you)奇數。根據(ju)不(bu)同層壓板(ban)(ban)的(de)組合(he)(he)，建筑(zhu)膠(jiao)合(he)(he)板(ban)(ban)的(de)厚度會有(you)(you)所不(bu)同。一(yi)般有(you)(you)3%、5%、9%、12%、15%、18%等幾種規格。當然，根據(ju)特殊(shu)情況會有(you)(you)其他厚度。

建筑膠合板的(de)(de)密(mi)(mi)度一般在0.5-0.8之(zhi)間。建(jian)筑膠合板(ban)(ban)的(de)(de)密(mi)(mi)度越(yue)高，質量越(yue)好。一般比(bi)同類木材大(da)。膠合時單(dan)位(wei)壓(ya)力(li)越(yue)高，建(jian)筑膠合板(ban)(ban)的(de)(de)密(mi)(mi)度越(yue)高。由(you)于木材在高溫(wen)下容易發(fa)生塑性變(bian)形，熱(re)壓(ya)結合的(de)(de)壓(ya)縮(suo)比(bi)大(da)于冷壓(ya)結合。建(jian)筑膠合板(ban)(ban)是由(you)縱橫交錯(cuo)的(de)(de)單(dan)板(ban)(ban)制成的(de)(de)，所(suo)以(yi)導熱(re)系數比(bi)同類木材低(di)。

建(jian)(jian)筑膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)單位(wei)壓(ya)力(li)越高(gao)，建(jian)(jian)筑膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)的密度(du)越高(gao)。由于木材(cai)在高(gao)溫下容易(yi)發生塑性變形，熱壓(ya)結合(he)(he)的壓(ya)縮比大于冷壓(ya)結合(he)(he)。建(jian)(jian)筑膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)由交錯排列的單板(ban)(ban)(ban)(ban)制成。其導熱系數(shu)低于同種類木材(cai)。建(jian)(jian)筑膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)的最外(wai)層單板(ban)(ban)(ban)(ban)叫(jiao)(jiao)面(mian)板(ban)(ban)(ban)(ban)，正(zheng)面(mian)板(ban)(ban)(ban)(ban)叫(jiao)(jiao)面(mian)板(ban)(ban)(ban)(ban)，反(fan)面(mian)板(ban)(ban)(ban)(ban)叫(jiao)(jiao)背(bei)板(ban)(ban)(ban)(ban)，內層單板(ban)(ban)(ban)(ban)叫(jiao)(jiao)芯板(ban)(ban)(ban)(ban)或中板(ban)(ban)(ban)(ban)。
