多層板是由(you)三(san)層(ceng)或多層(ceng)一毫米左右(you)的(de)實(shi)木單板(ban)(ban)(ban)(ban)或薄板(ban)(ban)(ban)(ban)膠貼熱壓(ya)制成，常(chang)見的(de)有三(san)夾板(ban)(ban)(ban)(ban)、五夾板(ban)(ban)(ban)(ban)、九(jiu)夾板(ban)(ban)(ban)(ban)和十二夾板(ban)(ban)(ban)(ban)(俗稱(cheng)三(san)合板(ban)(ban)(ban)(ban)，五厘板(ban)(ban)(ban)(ban)，九(jiu)厘板(ban)(ban)(ban)(ban)，十二厘板(ban)(ban)(ban)(ban))，結構強度好，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底板、板式家具(ju)的背板等(deng)各種(zhong)木制品工藝。多層板的長(chang)寬規格和(he)建筑模板的長(chang)寬規格一(yi)樣，基本是：1220×2440mm，而厚(hou)度(du)規格則一(yi)般(ban)有(you)：3、5、9、12、15、18mm等(deng)。主要樹種(zhong)有(you)：山(shan)樟、柳(liu)按、楊(yang)木、桉木等(deng)。

    多(duo)層板(ban)(ban)有(you)正反面的區別(bie)。挑選時，膠合板(ban)(ban)要木紋清晰，正面光潔平滑，不毛糙，要平整無滯手感。多(duo)層板(ban)(ban)選購(gou)應(ying)注意，多(duo)層板(ban)(ban)不應(ying)有(you)破(po)損、碰傷、硬傷、疤節等疵(ci)點。多(duo)層板(ban)(ban)無脫膠現象。

   有(you)(you)的多層(ceng)(ceng)板(ban)(ban)是將(jiang)兩個(ge)不同紋路的單板(ban)(ban)貼在一起制(zhi)成(cheng)的，所(suo)以(yi)在選擇上要注(zhu)意夾板(ban)(ban)拼縫(feng)處應嚴(yan)密，沒(mei)有(you)(you)高低不平現象(xiang)。挑選多層(ceng)(ceng)板(ban)(ban)時，應注(zhu)意挑選不散膠(jiao)的膠(jiao)合(he)板(ban)(ban)。如果手敲膠(jiao)合(he)板(ban)(ban)各部位時，聲音發脆，則(ze)證明質量良好，若聲音發悶，則(ze)表示(shi)膠(jiao)合(he)板(ban)(ban)已(yi)出現散膠(jiao)現象(xiang)。
