1、生產(chan)工藝不同

膠合(he)板(ban)(ban)是由木段旋切成單(dan)板(ban)(ban)或(huo)由木方刨切成薄木，再用膠粘劑膠合(he)而成的(de)三(san)層或(huo)多層的(de)板(ban)(ban)狀(zhuang)材料；密度板(ban)(ban)是將木材或(huo)其他植物分離(li)成纖維，利用纖維之間的(de)交織及其自身(shen)固(gu)有的(de)黏(nian)結物質，或(huo)者施加(jia)膠黏(nian)劑，在(zai)加(jia)熱或(huo)加(jia)壓的(de)條件下(xia)，制成的(de)板(ban)(ban)材。

2、產品分類不同(tong)

膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)根據其(qi)膠(jiao)(jiao)(jiao)合(he)(he)強度(du)分(fen)為(wei)四類(lei)：一類(lei)為(wei)耐氣候、耐沸(fei)水(shui)(shui)膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)。這(zhe)類(lei)膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)具有耐久、耐煮沸(fei)或蒸汽處理等性(xing)能(neng)(neng)，能(neng)(neng)在(zai)室外使(shi)(shi)用(yong)；二類(lei)膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)為(wei)耐水(shui)(shui)膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)，能(neng)(neng)在(zai)冷水(shui)(shui)中浸(jin)漬和短時(shi)間熱水(shui)(shui)浸(jin)漬；三類(lei)膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)為(wei)耐潮膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)，能(neng)(neng)在(zai)冷水(shui)(shui)中短時(shi)間浸(jin)漬，適于室內(nei)常溫下使(shi)(shi)用(yong)。用(yong)于家具和一般(ban)建筑(zhu)用(yong)途(tu)；四類(lei)膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)為(wei)不耐潮膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)，在(zai)室內(nei)常態(tai)下使(shi)(shi)用(yong)，一般(ban)用(yong)途(tu)膠(jiao)(jiao)(jiao)合(he)(he)板(ban)(ban)(ban)用(yong)材有櫸(ju)木(mu)(mu)、椴(duan)木(mu)(mu)、水(shui)(shui)曲柳(liu)、樺木(mu)(mu)、榆(yu)木(mu)(mu)、楊木(mu)(mu)等。

密(mi)(mi)(mi)度(du)(du)(du)板(ban)(ban)(ban)根據其(qi)密(mi)(mi)(mi)度(du)(du)(du)的(de)大小分為三(san)類：低(di)密(mi)(mi)(mi)度(du)(du)(du)板(ban)(ban)(ban)、中密(mi)(mi)(mi)度(du)(du)(du)板(ban)(ban)(ban)和高(gao)密(mi)(mi)(mi)度(du)(du)(du)板(ban)(ban)(ban)。

3、性能(neng)用途區分(fen)

膠(jiao)(jiao)合(he)板(ban)(ban)主要(yao)用(yong)于(yu)房屋(wu)建筑、內墻裝飾及(ji)門(men)面(mian)(mian)板(ban)(ban)等，在造(zao)型外(wai)表面(mian)(mian)，如弧形的(de)地(di)方，具(ju)有重量輕、彎曲性好(hao)特(te)點(dian)；密(mi)度板(ban)(ban)主要(yao)應用(yong)于(yu)家具(ju)制造(zao)、建筑材料、車(che)船制造(zao)、包(bao)裝材料等一(yi)些領域。膠(jiao)(jiao)合(he)板(ban)(ban)的(de)表面(mian)(mian)不如密(mi)度板(ban)(ban)表面(mian)(mian)光(guang)滑、平整；膠(jiao)(jiao)合(he)板(ban)(ban)相(xiang)對于(yu)密(mi)度板(ban)(ban)，材料含水率(lv)更(geng)(geng)(geng)加穩定，而且膠(jiao)(jiao)合(he)板(ban)(ban)跟密(mi)度板(ban)(ban)相(xiang)比，膠(jiao)(jiao)合(he)板(ban)(ban)防潮性能更(geng)(geng)(geng)好(hao)，握釘力膠(jiao)(jiao)合(he)板(ban)(ban)比密(mi)度板(ban)(ban)更(geng)(geng)(geng)強。
