【膠(jiao)合(he)板(ban) 密(mi)度(du)板(ban)】膠(jiao)合(he)板(ban)和密(mi)度(du)板(ban)的區別 密(mi)度(du)板(ban)和膠(jiao)合(he)板(ban)哪(na)個好

什么是膠合板

膠合板是拼接木施加膠合劑制成的(de)板材(cai)，板材(cai)的(de)表面(mian)平(ping)整，易于(yu)加工(gong)。

膠合(he)板(ban)是由木段旋(xuan)切成(cheng)單(dan)板(ban)或由木方(fang)刨切成(cheng)薄木，再用膠粘(zhan)劑(ji)膠合(he)而(er)成(cheng)的三層或多層的板(ban)狀材料，通常用奇數層單(dan)板(ban)，并(bing)使(shi)相鄰(lin)層單(dan)板(ban)的纖維(wei)方(fang)向互相垂直膠合(he)而(er)成(cheng)。板(ban)材產(chan)品外(wai)形扁(bian)平，寬厚(hou)比大，單(dan)位體積的表面(mian)積也很大。

什么是密度板

密度板一般是(shi)植物纖維和其(qi)他木質(zhi)纖維經過打(da)碎成(cheng)(cheng)(cheng)粉末，施加膠粘(zhan)劑制成(cheng)(cheng)(cheng)的(de)板(ban)(ban)材(cai)，板(ban)(ban)材(cai)具有握釘(ding)力較好(hao)，板(ban)(ban)材(cai)強(qiang)度高的(de)特點，由(you)于板(ban)(ban)材(cai)在市場(chang)上(shang)價格的(de)優勢(shi)使得其(qi)成(cheng)(cheng)(cheng)為(wei)現(xian)在家具市場(chang)常用(yong)的(de)板(ban)(ban)材(cai)。

密度板(ban)(ban)又名纖(xian)(xian)(xian)維板(ban)(ban)，是以木質(zhi)纖(xian)(xian)(xian)維或(huo)其他(ta)植(zhi)物(wu)素纖(xian)(xian)(xian)維為原料，施加蔦醛樹脂或(huo)其他(ta)適用的膠粘劑(ji)(ji)制成(cheng)的人造板(ban)(ban)。制造過程中可(ke)以施加膠粘劑(ji)(ji)和(he)(或(huo))添加劑(ji)(ji)。纖(xian)(xian)(xian)維板(ban)(ban)具有材(cai)質(zhi)均勻(yun)、縱橫強度差小、不易開裂等優點(dian)，用途(tu)廣泛。纖(xian)(xian)(xian)維板(ban)(ban)的缺點(dian)是背面有網紋，造成(cheng)板(ban)(ban)材(cai)兩面表(biao)面積不等，吸濕后(hou)因(yin)產生膨脹力差異而使板(ban)(ban)材(cai)翹曲變(bian)形(xing)。硬(ying)質(zhi)板(ban)(ban)材(cai)表(biao)面堅硬(ying)，釘釘困難，耐水性(xing)差。

膠合板和密度板的區別

1、生產工藝不同

膠(jiao)(jiao)合板(ban)(ban)是(shi)由(you)木(mu)段(duan)旋(xuan)切成(cheng)單板(ban)(ban)或(huo)(huo)由(you)木(mu)方刨切成(cheng)薄木(mu)，再用(yong)膠(jiao)(jiao)粘(zhan)劑膠(jiao)(jiao)合而成(cheng)的三(san)層或(huo)(huo)多層的板(ban)(ban)狀(zhuang)材料；密(mi)度板(ban)(ban)是(shi)將木(mu)材或(huo)(huo)其他植物(wu)分(fen)離成(cheng)纖維，利(li)用(yong)纖維之(zhi)間的交織及其自身固有的黏結(jie)物(wu)質(zhi)，或(huo)(huo)者施加膠(jiao)(jiao)黏劑，在加熱或(huo)(huo)加壓的條件下，制(zhi)成(cheng)的板(ban)(ban)材。

2、產品分類不同

膠(jiao)(jiao)合(he)(he)板(ban)(ban)根據(ju)其膠(jiao)(jiao)合(he)(he)強度(du)分(fen)為(wei)(wei)四類(lei)(lei)：一(yi)(yi)(yi)類(lei)(lei)為(wei)(wei)耐(nai)(nai)(nai)氣候、耐(nai)(nai)(nai)沸水膠(jiao)(jiao)合(he)(he)板(ban)(ban)。這(zhe)類(lei)(lei)膠(jiao)(jiao)合(he)(he)板(ban)(ban)具(ju)有耐(nai)(nai)(nai)久(jiu)、耐(nai)(nai)(nai)煮沸或蒸汽處理等(deng)性能(neng)，能(neng)在(zai)室(shi)外使(shi)用(yong)；二類(lei)(lei)膠(jiao)(jiao)合(he)(he)板(ban)(ban)為(wei)(wei)耐(nai)(nai)(nai)水膠(jiao)(jiao)合(he)(he)板(ban)(ban)，能(neng)在(zai)冷水中(zhong)浸漬和(he)短時(shi)間熱水浸漬；三類(lei)(lei)膠(jiao)(jiao)合(he)(he)板(ban)(ban)為(wei)(wei)耐(nai)(nai)(nai)潮膠(jiao)(jiao)合(he)(he)板(ban)(ban)，能(neng)在(zai)冷水中(zhong)短時(shi)間浸漬，適于室(shi)內常(chang)溫下使(shi)用(yong)。用(yong)于家具(ju)和(he)一(yi)(yi)(yi)般建筑用(yong)途；四類(lei)(lei)膠(jiao)(jiao)合(he)(he)板(ban)(ban)為(wei)(wei)不耐(nai)(nai)(nai)潮膠(jiao)(jiao)合(he)(he)板(ban)(ban)，在(zai)室(shi)內常(chang)態下使(shi)用(yong)，一(yi)(yi)(yi)般用(yong)途膠(jiao)(jiao)合(he)(he)板(ban)(ban)用(yong)材有櫸木(mu)(mu)、椴木(mu)(mu)、水曲柳、樺(hua)木(mu)(mu)、榆木(mu)(mu)、楊木(mu)(mu)等(deng)。

密(mi)度(du)板(ban)根據其密(mi)度(du)的大小(xiao)分為三類：低(di)密(mi)度(du)板(ban)、中密(mi)度(du)板(ban)和高密(mi)度(du)板(ban)。

3、性能用途區分

膠合(he)(he)板(ban)(ban)(ban)(ban)主(zhu)要用于(yu)(yu)房屋建筑(zhu)、內墻裝(zhuang)飾及門面(mian)(mian)板(ban)(ban)(ban)(ban)等，在造型外表(biao)面(mian)(mian)，如弧形的地(di)方，具有重(zhong)量輕、彎曲性好特點；密(mi)(mi)度板(ban)(ban)(ban)(ban)主(zhu)要應用于(yu)(yu)家具制造、建筑(zhu)材(cai)料(liao)(liao)、車船制造、包裝(zhuang)材(cai)料(liao)(liao)等一(yi)些領域(yu)。膠合(he)(he)板(ban)(ban)(ban)(ban)的表(biao)面(mian)(mian)不如密(mi)(mi)度板(ban)(ban)(ban)(ban)表(biao)面(mian)(mian)光滑、平整；膠合(he)(he)板(ban)(ban)(ban)(ban)相對于(yu)(yu)密(mi)(mi)度板(ban)(ban)(ban)(ban)，材(cai)料(liao)(liao)含水率更(geng)加穩(wen)定，而且膠合(he)(he)板(ban)(ban)(ban)(ban)跟密(mi)(mi)度板(ban)(ban)(ban)(ban)相比，膠合(he)(he)板(ban)(ban)(ban)(ban)防潮性能(neng)更(geng)好，握釘力(li)膠合(he)(he)板(ban)(ban)(ban)(ban)比密(mi)(mi)度板(ban)(ban)(ban)(ban)更(geng)強。

密度板和膠合板哪個好_看用途

以衣(yi)(yi)柜(ju)(ju)為例，一般到衣(yi)(yi)柜(ju)(ju)店里買(mai)衣(yi)(yi)柜(ju)(ju)，他們會給你用(yong)密度板(ban)；裝(zhuang)修公司裝(zhuang)修的話，也就是木工(gong)，會用(yong)大芯板(ban)做；膠合板(ban)，一般人都不會用(yong)它(ta)做衣(yi)(yi)柜(ju)(ju)的。
