1、生產工藝(yi)不同

膠合板(ban)是由木(mu)段(duan)旋(xuan)切成(cheng)(cheng)單(dan)板(ban)或(huo)由木(mu)方(fang)刨切成(cheng)(cheng)薄木(mu)，再(zai)用膠粘(zhan)劑(ji)膠合而成(cheng)(cheng)的(de)(de)三層(ceng)或(huo)多(duo)層(ceng)的(de)(de)板(ban)狀材料(liao)；密度板(ban)是將(jiang)木(mu)材或(huo)其(qi)他(ta)植物(wu)分離成(cheng)(cheng)纖(xian)維(wei)，利用纖(xian)維(wei)之間的(de)(de)交織及其(qi)自身(shen)固(gu)有(you)的(de)(de)黏(nian)結(jie)物(wu)質(zhi)，或(huo)者(zhe)施加膠黏(nian)劑(ji)，在加熱(re)或(huo)加壓的(de)(de)條件下，制成(cheng)(cheng)的(de)(de)板(ban)材。

2、產品分(fen)類(lei)不(bu)同(tong)

膠(jiao)合(he)(he)板(ban)(ban)根據其膠(jiao)合(he)(he)強度分為四類(lei)(lei)(lei)：一類(lei)(lei)(lei)為耐(nai)(nai)氣候、耐(nai)(nai)沸水膠(jiao)合(he)(he)板(ban)(ban)。這類(lei)(lei)(lei)膠(jiao)合(he)(he)板(ban)(ban)具有(you)耐(nai)(nai)久(jiu)、耐(nai)(nai)煮(zhu)沸或蒸汽處(chu)理(li)等性(xing)能(neng)(neng)，能(neng)(neng)在(zai)室(shi)外使用(yong)(yong)；二類(lei)(lei)(lei)膠(jiao)合(he)(he)板(ban)(ban)為耐(nai)(nai)水膠(jiao)合(he)(he)板(ban)(ban)，能(neng)(neng)在(zai)冷水中浸(jin)漬(zi)(zi)和短時(shi)間熱(re)水浸(jin)漬(zi)(zi)；三類(lei)(lei)(lei)膠(jiao)合(he)(he)板(ban)(ban)為耐(nai)(nai)潮(chao)膠(jiao)合(he)(he)板(ban)(ban)，能(neng)(neng)在(zai)冷水中短時(shi)間浸(jin)漬(zi)(zi)，適于室(shi)內常溫下使用(yong)(yong)。用(yong)(yong)于家具和一般(ban)建筑用(yong)(yong)途；四類(lei)(lei)(lei)膠(jiao)合(he)(he)板(ban)(ban)為不耐(nai)(nai)潮(chao)膠(jiao)合(he)(he)板(ban)(ban)，在(zai)室(shi)內常態下使用(yong)(yong)，一般(ban)用(yong)(yong)途膠(jiao)合(he)(he)板(ban)(ban)用(yong)(yong)材(cai)有(you)櫸木(mu)、椴木(mu)、水曲柳、樺木(mu)、榆木(mu)、楊木(mu)等。

密(mi)(mi)度(du)(du)板根據(ju)其(qi)密(mi)(mi)度(du)(du)的大小(xiao)分(fen)為(wei)三類：低(di)密(mi)(mi)度(du)(du)板、中密(mi)(mi)度(du)(du)板和高密(mi)(mi)度(du)(du)板。

3、性能用途區分

膠(jiao)合板(ban)(ban)(ban)主(zhu)要用(yong)(yong)于房屋建(jian)筑(zhu)、內墻裝飾及門面(mian)板(ban)(ban)(ban)等(deng)，在(zai)造型外表(biao)面(mian)，如(ru)(ru)弧形的地方，具(ju)有重量輕、彎(wan)曲性好特(te)點；密度板(ban)(ban)(ban)主(zhu)要應用(yong)(yong)于家具(ju)制造、建(jian)筑(zhu)材料、車船制造、包(bao)裝材料等(deng)一(yi)些領域。膠(jiao)合板(ban)(ban)(ban)的表(biao)面(mian)不如(ru)(ru)密度板(ban)(ban)(ban)表(biao)面(mian)光滑、平(ping)整；膠(jiao)合板(ban)(ban)(ban)相對于密度板(ban)(ban)(ban)，材料含水(shui)率更加穩定，而且膠(jiao)合板(ban)(ban)(ban)跟密度板(ban)(ban)(ban)相比，膠(jiao)合板(ban)(ban)(ban)防潮性能更好，握釘力膠(jiao)合板(ban)(ban)(ban)比密度板(ban)(ban)(ban)更強。
