由木質纖(xian)維(wei)素纖(xian)維(wei)交織成型并利用其固有(you)膠粘性(xing)能制(zhi)成的人造板。制(zhi)造過程中可以施加膠粘劑和(或)添加劑。

纖(xian)維(wei)板(ban)(ban)(ban)(ban)又名密度板(ban)(ban)(ban)(ban)，是以(yi)木(mu)質纖(xian)維(wei)或(huo)其(qi)他植物素纖(xian)維(wei)為原料(liao)，安徽(hui)刨花(hua)板(ban)(ban)(ban)(ban)，施(shi)(shi)加(jia)脲醛樹脂或(huo)其(qi)他適用(yong)的(de)膠粘劑(ji)制成的(de)人造(zao)板(ban)(ban)(ban)(ban)。制造(zao)過(guo)程中可以(yi)施(shi)(shi)加(jia)膠粘劑(ji)和(或(huo))添加(jia)劑(ji)。纖(xian)維(wei)板(ban)(ban)(ban)(ban)具(ju)有(you)材(cai)質均勻、縱橫強度差小、不易開(kai)裂等優點(dian)，用(yong)途廣泛(fan)。制造(zao) 1立方(fang)米(mi)纖(xian)維(wei)板(ban)(ban)(ban)(ban)約需2.5~3立方(fang)米(mi)的(de)木(mu)材(cai)，可代替3立方(fang)米(mi)鋸材(cai)或(huo)5立方(fang)米(mi)原木(mu)。發展(zhan)纖(xian)維(wei)板(ban)(ban)(ban)(ban)生產是木(mu)材(cai)資源(yuan)綜(zong)合利用(yong)的(de)有(you)效途徑。

軟(ruan)質(zhi)(zhi)纖(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)和采(cai)用(yong)濕法成(cheng)型干(gan)熱(re)(re)(re)壓(ya)(ya)(ya)(ya)工藝（又稱濕干(gan)法）的硬質(zhi)(zhi)纖(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)，其板(ban)(ban)(ban)(ban)(ban)坯(pi)(pi)(pi)都(dou)要經(jing)過干(gan)燥。干(gan)燥設備有間歇式(shi)和連續(xu)式(shi)兩大類。干(gan)燥 1千克水(shui)消耗1.6～1.8千克蒸氣。軟(ruan)質(zhi)(zhi)纖(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)坯(pi)(pi)(pi)干(gan)燥后的終含(han)(han)水(shui)率(lv)為1～3%。用(yong)濕干(gan)法制造硬質(zhi)(zhi)纖(xian)維(wei)(wei)板(ban)(ban)(ban)(ban)(ban)時，板(ban)(ban)(ban)(ban)(ban)坯(pi)(pi)(pi)含(han)(han)水(shui)率(lv)不宜太高，否則熱(re)(re)(re)壓(ya)(ya)(ya)(ya)時易于發生(sheng)鼓(gu)泡在熱(re)(re)(re)壓(ya)(ya)(ya)(ya)過程中(zhong)，刨花(hua)(hua)板(ban)(ban)(ban)(ban)(ban)品(pin)牌，板(ban)(ban)(ban)(ban)(ban)坯(pi)(pi)(pi)的表(biao)層(ceng)(ceng)與芯(xin)(xin)層(ceng)(ceng)會出現(xian)溫差，厚(hou)度較大的中(zhong)密度板(ban)(ban)(ban)(ban)(ban)坯(pi)(pi)(pi)表(biao)芯(xin)(xin)層(ceng)(ceng)溫差可達40～60℃，什么是刨花(hua)(hua)板(ban)(ban)(ban)(ban)(ban)，影響芯(xin)(xin)層(ceng)(ceng)樹脂固(gu)化率(lv)。可用(yong)常規(gui)加熱(re)(re)(re)和高頻加熱(re)(re)(re)消除溫差，并縮短熱(re)(re)(re)壓(ya)(ya)(ya)(ya)周期。

尋求資源豐富、價格低廉的膠(jiao)(jiao)粘(zhan)(zhan)劑(ji)是發展刨花(hua)板(ban)生產重要因素，因此(ci)林產資源和造紙制(zhi)漿廢液(ye)的有效(xiao)利用已(yi)越來越受(shou)到重視。單寧甲醛(quan)膠(jiao)(jiao)及(ji)亞硫酸鹽紙漿廢液(ye)膠(jiao)(jiao)用作膠(jiao)(jiao)粘(zhan)(zhan)劑(ji)已(yi)取得成(cheng)功，水泥(ni)、石(shi)膏(gao)等制(zhi)成(cheng)的無機膠(jiao)(jiao)粘(zhan)(zhan)劑(ji)也(ye)已(yi)得到應用；而更(geng)(geng)具吸引(yin)力的是無膠(jiao)(jiao)粘(zhan)(zhan)合新(xin)技術，它的出(chu)現將(jiang)使刨花(hua)板(ban)工(gong)業(ye)發生根(gen)本性變革(ge)。至于(yu)刨花(hua)板(ban)本身，由于(yu)定(ding)向型結(jie)構(gou)(gou)在力學性能(neng)方面(mian)(mian)顯著優于(yu)隨機型結(jie)構(gou)(gou)，可以用來代(dai)替膠(jiao)(jiao)合板(ban)甚至部分鋸制(zhi)板(ban)材(cai)，故(gu)大有發展前途。刨花(hua)板(ban)表面(mian)(mian)裝(zhuang)飾加工(gong)也(ye)將(jiang)出(chu)現更(geng)(geng)多的新(xin)材(cai)料(liao)和新(xin)工(gong)藝，并有可能(neng)通過多品(pin)種多功能(neng)飾面(mian)(mian)材(cai)料(liao)預制(zhi)的化(hua)，形成(cheng)一個獨立的新(xin)興(xing)工(gong)業(ye)門類。
