多層板是(shi)由三層或(huo)多層一毫(hao)米左右的實木單板(ban)(ban)(ban)(ban)或(huo)薄板(ban)(ban)(ban)(ban)膠貼熱壓制成(cheng)，常見(jian)的有三夾板(ban)(ban)(ban)(ban)、五夾板(ban)(ban)(ban)(ban)、九夾板(ban)(ban)(ban)(ban)和十(shi)二(er)夾板(ban)(ban)(ban)(ban)(俗稱(cheng)三合(he)板(ban)(ban)(ban)(ban)，五厘(li)板(ban)(ban)(ban)(ban)，九厘(li)板(ban)(ban)(ban)(ban)，十(shi)二(er)厘(li)板(ban)(ban)(ban)(ban))，結(jie)構強度好(hao)(hao)，穩定性好(hao)(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)底板(ban)(ban)、板(ban)(ban)式(shi)家具的(de)背板(ban)(ban)等(deng)各種木制品工藝。多層(ceng)板(ban)(ban)的(de)長寬規(gui)格和建筑模板(ban)(ban)的(de)長寬規(gui)格一(yi)樣，基本是：1220×2440mm，而厚度(du)規(gui)格則一(yi)般有(you)：3、5、9、12、15、18mm等(deng)。主要樹種有(you)：山樟(zhang)、柳按、楊(yang)木、桉木等(deng)。

   多層(ceng)板有正(zheng)反面(mian)的(de)區別。挑選時，膠合板要木紋清晰，正(zheng)面(mian)光潔平滑，不毛糙，要平整(zheng)無滯手感(gan)。多層(ceng)板選購應(ying)注意，多層(ceng)板不應(ying)有破(po)損、碰傷(shang)、硬傷(shang)、疤節等疵點。多層(ceng)板無脫膠現(xian)象。

    有的多(duo)層板(ban)(ban)是將(jiang)兩個不同紋路的單板(ban)(ban)貼在(zai)一起制成的，所以在(zai)選(xuan)擇上要注(zhu)意(yi)夾板(ban)(ban)拼縫處(chu)應(ying)嚴密，沒有高低不平(ping)現象。挑選(xuan)多(duo)層板(ban)(ban)時，應(ying)注(zhu)意(yi)挑選(xuan)不散膠的膠合(he)(he)板(ban)(ban)。如(ru)果手(shou)敲膠合(he)(he)板(ban)(ban)各部位時，聲(sheng)音發脆，則證(zheng)明質(zhi)量良好，若(ruo)聲(sheng)音發悶，則表示膠合(he)(he)板(ban)(ban)已(yi)出(chu)現散膠現象。
