多層板是由三(san)層或多層一(yi)毫(hao)米左右(you)的(de)(de)實木單(dan)板(ban)(ban)(ban)(ban)或薄板(ban)(ban)(ban)(ban)膠貼熱壓制成，常見的(de)(de)有三(san)夾板(ban)(ban)(ban)(ban)、五(wu)夾板(ban)(ban)(ban)(ban)、九(jiu)(jiu)夾板(ban)(ban)(ban)(ban)和十二夾板(ban)(ban)(ban)(ban)(俗稱三(san)合板(ban)(ban)(ban)(ban)，五(wu)厘(li)板(ban)(ban)(ban)(ban)，九(jiu)(jiu)厘(li)板(ban)(ban)(ban)(ban)，十二厘(li)板(ban)(ban)(ban)(ban))，結構(gou)強(qiang)度(du)好，穩定(ding)性好。

   膠合板含膠量大，施工時要做好封邊處理，晝減少污染。膠合板主要用于裝飾面板的(de)底板(ban)、板(ban)式(shi)家具的(de)背板(ban)等(deng)各(ge)種木制品(pin)工藝。多層板(ban)的(de)長(chang)寬(kuan)規格和建(jian)筑模(mo)板(ban)的(de)長(chang)寬(kuan)規格一樣，基本是：1220×2440mm，而厚(hou)度規格則一般有(you)：3、5、9、12、15、18mm等(deng)。主要樹種有(you)：山(shan)樟、柳按、楊(yang)木、桉木等(deng)。

   多(duo)層(ceng)板(ban)(ban)有(you)正(zheng)反(fan)面的區(qu)別。挑(tiao)選(xuan)時(shi)，膠合(he)板(ban)(ban)要(yao)木紋(wen)清晰，正(zheng)面光潔平(ping)滑，不(bu)毛(mao)糙，要(yao)平(ping)整無滯手感。多(duo)層(ceng)板(ban)(ban)選(xuan)購應注(zhu)意，多(duo)層(ceng)板(ban)(ban)不(bu)應有(you)破損、碰傷、硬(ying)傷、疤節(jie)等(deng)疵點。多(duo)層(ceng)板(ban)(ban)無脫膠現象。

   有(you)的多層(ceng)板(ban)(ban)是將兩個不(bu)同紋路的單板(ban)(ban)貼在(zai)(zai)一起制成的，所(suo)以在(zai)(zai)選(xuan)擇上(shang)要注意(yi)夾板(ban)(ban)拼縫處應嚴密(mi)，沒有(you)高低(di)不(bu)平現象。挑選(xuan)多層(ceng)板(ban)(ban)時，應注意(yi)挑選(xuan)不(bu)散膠(jiao)的膠(jiao)合板(ban)(ban)。如(ru)果手敲膠(jiao)合板(ban)(ban)各部(bu)位(wei)時，聲音(yin)發(fa)脆，則證明質(zhi)量良好，若聲音(yin)發(fa)悶，則表示(shi)膠(jiao)合板(ban)(ban)已出(chu)現散膠(jiao)現象。
