【膠合板(ban) 密(mi)度(du)板(ban)】膠合板(ban)和密(mi)度(du)板(ban)的區別 密(mi)度(du)板(ban)和膠合板(ban)哪(na)個(ge)好
什么是膠合板
膠合板是拼接木施(shi)加膠合劑(ji)制成的(de)板(ban)材,板(ban)材的(de)表面平整,易(yi)于加工。
膠合(he)板(ban)是由(you)木(mu)段旋切成(cheng)單(dan)板(ban)或由(you)木(mu)方刨切成(cheng)薄木(mu),再用膠粘(zhan)劑膠合(he)而(er)(er)成(cheng)的三(san)層或多層的板(ban)狀材料(liao),通(tong)常用奇數層單(dan)板(ban),并(bing)使相鄰層單(dan)板(ban)的纖維方向(xiang)互(hu)相垂(chui)直膠合(he)而(er)(er)成(cheng)。板(ban)材產品外形扁平,寬厚比大,單(dan)位體積的表面(mian)積也很大。
什么是密度板
密度板一般是植(zhi)物纖(xian)維和其(qi)他木質纖(xian)維經過打碎成(cheng)粉末,施加膠粘劑制成(cheng)的(de)(de)板(ban)(ban)材,板(ban)(ban)材具(ju)有握釘力(li)較好(hao),板(ban)(ban)材強度高的(de)(de)特點,由于板(ban)(ban)材在市場上價(jia)格的(de)(de)優勢使(shi)得其(qi)成(cheng)為現在家具(ju)市場常用(yong)的(de)(de)板(ban)(ban)材。
密(mi)度板(ban)又名纖(xian)維(wei)板(ban),是以木(mu)質(zhi)纖(xian)維(wei)或(huo)其他(ta)(ta)植物(wu)素纖(xian)維(wei)為原料,施(shi)(shi)加蔦醛樹(shu)脂或(huo)其他(ta)(ta)適用(yong)的(de)(de)膠粘劑制成的(de)(de)人造板(ban)。制造過程中可以施(shi)(shi)加膠粘劑和(或(huo))添加劑。纖(xian)維(wei)板(ban)具有(you)材(cai)質(zhi)均勻、縱橫強(qiang)度差小、不易(yi)開裂等優點,用(yong)途廣泛。纖(xian)維(wei)板(ban)的(de)(de)缺(que)點是背面有(you)網紋,造成板(ban)材(cai)兩面表面積不等,吸濕后因(yin)產生膨脹力差異而使板(ban)材(cai)翹曲變形。硬(ying)(ying)質(zhi)板(ban)材(cai)表面堅硬(ying)(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
膠合板是由木(mu)(mu)段旋(xuan)切成(cheng)(cheng)(cheng)單板或由木(mu)(mu)方刨切成(cheng)(cheng)(cheng)薄木(mu)(mu),再(zai)用(yong)膠粘(zhan)劑膠合而成(cheng)(cheng)(cheng)的(de)三層或多層的(de)板狀材料;密度(du)板是將木(mu)(mu)材或其他植物(wu)分離成(cheng)(cheng)(cheng)纖維(wei),利用(yong)纖維(wei)之間的(de)交織及其自身(shen)固有的(de)黏結物(wu)質(zhi),或者施加膠黏劑,在(zai)加熱或加壓(ya)的(de)條件下,制成(cheng)(cheng)(cheng)的(de)板材。
2、產品分類不同
膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban)根據其膠(jiao)(jiao)(jiao)合(he)(he)(he)強(qiang)度分(fen)為(wei)四類(lei)(lei):一類(lei)(lei)為(wei)耐氣(qi)候(hou)、耐沸水膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban)。這類(lei)(lei)膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban)具(ju)有耐久、耐煮沸或蒸汽處理等(deng)性能(neng),能(neng)在(zai)室外使(shi)用(yong)(yong);二(er)類(lei)(lei)膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban)為(wei)耐水膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban),能(neng)在(zai)冷水中(zhong)浸(jin)漬(zi)和(he)短(duan)時(shi)間熱水浸(jin)漬(zi);三類(lei)(lei)膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban)為(wei)耐潮(chao)(chao)膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban),能(neng)在(zai)冷水中(zhong)短(duan)時(shi)間浸(jin)漬(zi),適于室內(nei)常(chang)溫下(xia)使(shi)用(yong)(yong)。用(yong)(yong)于家(jia)具(ju)和(he)一般建筑(zhu)用(yong)(yong)途(tu);四類(lei)(lei)膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban)為(wei)不耐潮(chao)(chao)膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban),在(zai)室內(nei)常(chang)態下(xia)使(shi)用(yong)(yong),一般用(yong)(yong)途(tu)膠(jiao)(jiao)(jiao)合(he)(he)(he)板(ban)(ban)(ban)用(yong)(yong)材(cai)有櫸木、椴(duan)木、水曲柳、樺木、榆(yu)木、楊(yang)木等(deng)。
密(mi)(mi)度(du)板(ban)根據其(qi)密(mi)(mi)度(du)的大小分為三類:低密(mi)(mi)度(du)板(ban)、中密(mi)(mi)度(du)板(ban)和高(gao)密(mi)(mi)度(du)板(ban)。
3、性能用途區分
膠合(he)板(ban)(ban)(ban)(ban)主要用于房屋建(jian)筑、內(nei)墻裝飾及門面(mian)(mian)板(ban)(ban)(ban)(ban)等(deng),在(zai)造(zao)型外(wai)表(biao)面(mian)(mian),如(ru)弧形的地方,具(ju)有重(zhong)量(liang)輕、彎曲性好(hao)特點;密(mi)(mi)度板(ban)(ban)(ban)(ban)主要應用于家具(ju)制(zhi)造(zao)、建(jian)筑材料(liao)、車船制(zhi)造(zao)、包裝材料(liao)等(deng)一些領域(yu)。膠合(he)板(ban)(ban)(ban)(ban)的表(biao)面(mian)(mian)不如(ru)密(mi)(mi)度板(ban)(ban)(ban)(ban)表(biao)面(mian)(mian)光滑、平整;膠合(he)板(ban)(ban)(ban)(ban)相對于密(mi)(mi)度板(ban)(ban)(ban)(ban),材料(liao)含水率更(geng)加穩定,而且(qie)膠合(he)板(ban)(ban)(ban)(ban)跟密(mi)(mi)度板(ban)(ban)(ban)(ban)相比,膠合(he)板(ban)(ban)(ban)(ban)防(fang)潮性能更(geng)好(hao),握釘力(li)膠合(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)柜(ju)為例,一(yi)般(ban)(ban)到衣(yi)柜(ju)店里買衣(yi)柜(ju),他們(men)會(hui)給(gei)你用密度板(ban);裝修公司裝修的話(hua),也就是木工,會(hui)用大芯板(ban)做;膠(jiao)合板(ban),一(yi)般(ban)(ban)人都(dou)不會(hui)用它做衣(yi)柜(ju)的。
