多層板是由三層或多層一(yi)毫米(mi)左(zuo)右的實木(mu)單板(ban)(ban)(ban)(ban)或薄板(ban)(ban)(ban)(ban)膠(jiao)貼(tie)熱壓制(zhi)成，常見的有三夾板(ban)(ban)(ban)(ban)、五(wu)夾板(ban)(ban)(ban)(ban)、九夾板(ban)(ban)(ban)(ban)和十(shi)二夾板(ban)(ban)(ban)(ban)(俗稱三合板(ban)(ban)(ban)(ban)，五(wu)厘(li)板(ban)(ban)(ban)(ban)，九厘(li)板(ban)(ban)(ban)(ban)，十(shi)二厘(li)板(ban)(ban)(ban)(ban))，結構強度好(hao)，穩(wen)定(ding)性好(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底板(ban)(ban)、板(ban)(ban)式家(jia)具(ju)的背板(ban)(ban)等各種(zhong)木(mu)制品工藝。多(duo)層板(ban)(ban)的長寬規格(ge)和建(jian)筑模板(ban)(ban)的長寬規格(ge)一樣，基本(ben)是：1220×2440mm，而(er)厚度(du)規格(ge)則(ze)一般有(you)：3、5、9、12、15、18mm等。主(zhu)要(yao)樹種(zhong)有(you)：山(shan)樟、柳(liu)按(an)、楊木(mu)、桉木(mu)等。

   多(duo)層(ceng)(ceng)板(ban)有正反面的區別。挑(tiao)選時，膠合板(ban)要木紋(wen)清晰，正面光潔平滑(hua)，不毛糙，要平整無滯(zhi)手感。多(duo)層(ceng)(ceng)板(ban)選購應(ying)注意，多(duo)層(ceng)(ceng)板(ban)不應(ying)有破損(sun)、碰傷、硬(ying)傷、疤節(jie)等疵點。多(duo)層(ceng)(ceng)板(ban)無脫(tuo)膠現象。

 ;  有的(de)(de)多層板(ban)(ban)是將兩個不(bu)同紋路(lu)的(de)(de)單板(ban)(ban)貼在一起(qi)制成的(de)(de)，所(suo)以在選(xuan)擇上(shang)要(yao)注意夾(jia)板(ban)(ban)拼縫處應嚴密，沒有高低(di)不(bu)平現(xian)象。挑選(xuan)多層板(ban)(ban)時，應注意挑選(xuan)不(bu)散膠(jiao)的(de)(de)膠(jiao)合(he)板(ban)(ban)。如(ru)果(guo)手敲膠(jiao)合(he)板(ban)(ban)各部(bu)位時，聲音發脆，則證(zheng)明質量良(liang)好，若聲音發悶，則表(biao)示(shi)膠(jiao)合(he)板(ban)(ban)已出現(xian)散膠(jiao)現(xian)象。
