多層板是(shi)由三(san)層或多層一毫米左(zuo)右的實木(mu)單板(ban)(ban)(ban)(ban)或薄(bo)板(ban)(ban)(ban)(ban)膠貼熱(re)壓制成，常(chang)見的有三(san)夾(jia)(jia)板(ban)(ban)(ban)(ban)、五夾(jia)(jia)板(ban)(ban)(ban)(ban)、九夾(jia)(jia)板(ban)(ban)(ban)(ban)和(he)十(shi)二夾(jia)(jia)板(ban)(ban)(ban)(ban)(俗稱三(san)合(he)板(ban)(ban)(ban)(ban)，五厘(li)(li)板(ban)(ban)(ban)(ban)，九厘(li)(li)板(ban)(ban)(ban)(ban)，十(shi)二厘(li)(li)板(ban)(ban)(ban)(ban))，結構強度好，穩定性好。

   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底(di)板(ban)(ban)、板(ban)(ban)式(shi)家(jia)具的背(bei)板(ban)(ban)等各(ge)種木(mu)制品工藝(yi)。多層板(ban)(ban)的長寬規格和建筑模板(ban)(ban)的長寬規格一樣，基本(ben)是(shi)：1220×2440mm，而厚度規格則(ze)一般有：3、5、9、12、15、18mm等。主要樹種有：山樟、柳按、楊木(mu)、桉木(mu)等。

   多(duo)層(ceng)板(ban)(ban)有正反面的區別。挑選時，膠(jiao)合板(ban)(ban)要(yao)木(mu)紋清晰，正面光潔平滑，不(bu)毛糙，要(yao)平整(zheng)無(wu)滯手(shou)感。多(duo)層(ceng)板(ban)(ban)選購(gou)應(ying)(ying)注(zhu)意，多(duo)層(ceng)板(ban)(ban)不(bu)應(ying)(ying)有破損、碰傷、硬(ying)傷、疤節等疵點。多(duo)層(ceng)板(ban)(ban)無(wu)脫膠(jiao)現象。

   有(you)的多層板(ban)(ban)是將兩(liang)個不同紋路的單板(ban)(ban)貼在一起制成(cheng)的，所以在選擇上要注(zhu)意夾板(ban)(ban)拼縫處應嚴密，沒有(you)高低不平現(xian)象。挑選多層板(ban)(ban)時(shi)，應注(zhu)意挑選不散膠(jiao)的膠(jiao)合(he)板(ban)(ban)。如果手(shou)敲膠(jiao)合(he)板(ban)(ban)各(ge)部位時(shi)，聲音發脆(cui)，則證明質量良好，若聲音發悶，則表示膠(jiao)合(he)板(ban)(ban)已(yi)出現(xian)散膠(jiao)現(xian)象。
