多層板是(shi)由三層或多層一毫米(mi)左右的實木單板(ban)(ban)或薄板(ban)(ban)膠貼(tie)熱壓制成，常(chang)見(jian)的有三夾板(ban)(ban)、五夾板(ban)(ban)、九夾板(ban)(ban)和十二(er)夾板(ban)(ban)(俗稱三合(he)板(ban)(ban)，五厘板(ban)(ban)，九厘板(ban)(ban)，十二(er)厘板(ban)(ban))，結構(gou)強度好(hao)，穩定性(xing)好(hao)。

   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)(de)底(di)板(ban)(ban)、板(ban)(ban)式家具的(de)(de)背板(ban)(ban)等各(ge)種木制品工(gong)藝(yi)。多層板(ban)(ban)的(de)(de)長(chang)寬(kuan)規格(ge)和建筑模板(ban)(ban)的(de)(de)長(chang)寬(kuan)規格(ge)一(yi)樣，基本是(shi)：1220×2440mm，而厚度規格(ge)則(ze)一(yi)般有(you)(you)：3、5、9、12、15、18mm等。主要樹種有(you)(you)：山樟、柳(liu)按、楊木、桉木等。

   多(duo)層板(ban)有正反面(mian)的區別。挑(tiao)選(xuan)時，膠合(he)板(ban)要木(mu)紋清晰(xi)，正面(mian)光潔平(ping)滑，不毛(mao)糙(cao)，要平(ping)整無滯手感。多(duo)層板(ban)選(xuan)購應(ying)注意(yi)，多(duo)層板(ban)不應(ying)有破損(sun)、碰傷、硬傷、疤節等疵點。多(duo)層板(ban)無脫膠現(xian)象。

   有(you)的多層板(ban)(ban)(ban)(ban)是(shi)將兩(liang)個不同紋(wen)路(lu)的單板(ban)(ban)(ban)(ban)貼在(zai)(zai)一起制成的，所以在(zai)(zai)選(xuan)擇上要注意夾板(ban)(ban)(ban)(ban)拼縫處應嚴密，沒(mei)有(you)高低不平現(xian)象。挑選(xuan)多層板(ban)(ban)(ban)(ban)時，應注意挑選(xuan)不散膠(jiao)的膠(jiao)合(he)板(ban)(ban)(ban)(ban)。如果手(shou)敲膠(jiao)合(he)板(ban)(ban)(ban)(ban)各(ge)部(bu)位時，聲(sheng)音(yin)發(fa)脆，則證明質量(liang)良(liang)好，若聲(sheng)音(yin)發(fa)悶(men)，則表示(shi)膠(jiao)合(he)板(ban)(ban)(ban)(ban)已出(chu)現(xian)散膠(jiao)現(xian)象。
