一、阻燃板的防火等級

阻燃(ran)(ran)(ran)(ran)(ran)(ran)板分為六個等(deng)級，A級：不(bu)燃(ran)(ran)(ran)(ran)(ran)(ran)性(xing)建(jian)筑材(cai)(cai)料(liao)。A1級：不(bu)燃(ran)(ran)(ran)(ran)(ran)(ran)，不(bu)起(qi)(qi)明火(huo)。A2級：不(bu)燃(ran)(ran)(ran)(ran)(ran)(ran)，要(yao)測量煙，要(yao)合格。B1級：難(nan)燃(ran)(ran)(ran)(ran)(ran)(ran)性(xing)建(jian)筑材(cai)(cai)料(liao)，有(you)(you)較好的(de)(de)阻燃(ran)(ran)(ran)(ran)(ran)(ran)作用(yong)，其在(zai)(zai)空(kong)氣中遇明火(huo)或在(zai)(zai)高(gao)溫作用(yong)下(xia)(xia)難(nan)起(qi)(qi)火(huo)，不(bu)易(yi)很快發生蔓(man)(man)延，且(qie)當火(huo)源移開后燃(ran)(ran)(ran)(ran)(ran)(ran)燒(shao)立即(ji)停止。B2級：可(ke)燃(ran)(ran)(ran)(ran)(ran)(ran)性(xing)建(jian)筑材(cai)(cai)料(liao)，有(you)(you)一定的(de)(de)阻燃(ran)(ran)(ran)(ran)(ran)(ran)作用(yong)，在(zai)(zai)空(kong)氣中遇明火(huo)或在(zai)(zai)高(gao)溫作用(yong)下(xia)(xia)會立即(ji)起(qi)(qi)火(huo)燃(ran)(ran)(ran)(ran)(ran)(ran)燒(shao)，易(yi)導(dao)致(zhi)火(huo)災的(de)(de)蔓(man)(man)延。B3級：易(yi)燃(ran)(ran)(ran)(ran)(ran)(ran)性(xing)建(jian)筑材(cai)(cai)料(liao)，無(wu)任何阻燃(ran)(ran)(ran)(ran)(ran)(ran)效果，極易(yi)燃(ran)(ran)(ran)(ran)(ran)(ran)燒(shao)，火(huo)災危險性(xing)很大。

二、阻燃板規格尺寸

阻燃板尺寸規格一般都為2440mm（長）x 1220mm（寬）x 厚度。其中厚度常見的有5mm、9mm、12mm、15mm、16mm、18mm，厚度越厚，其阻燃性能越強，不同的場所裝修要求厚度不同。阻燃板的質量、厚度、尺寸等因素對于消防安全非常重要，選購的阻燃板品牌要防火等級高，環保性能好。

三、阻燃板需要刷防火涂料嗎

如果木板(ban)(ban)的阻(zu)(zu)燃程(cheng)度(du)能夠達到防火設計(ji)的要求那就(jiu)沒必要做防火涂料(liao)，如果達不(bu)到只能通過(guo)涂刷防火涂料(liao)來(lai)提高防火性能，不(bu)過(guo)需要注意的是，防火等級(ji)低(di)的阻(zu)(zu)燃板(ban)(ban)是不(bu)能升級(ji)成為防火等級(ji)高的阻(zu)(zu)燃板(ban)(ban)的，即使刷了(le)防火涂料(liao)也不(bu)能夠當做高等級(ji)阻(zu)(zu)燃板(ban)(ban)使用。

四、阻燃板和木工板的區別

木(mu)工(gong)板(ban)(ban)(ban)(ban)(ban)是在(zai)膠(jiao)(jiao)(jiao)合(he)板(ban)(ban)(ban)(ban)(ban)生產基礎上(shang)，以木(mu)板(ban)(ban)(ban)(ban)(ban)條拼(pin)接或(huo)空心板(ban)(ban)(ban)(ban)(ban)作芯板(ban)(ban)(ban)(ban)(ban)，兩面(mian)覆(fu)蓋兩層(ceng)或(huo)多(duo)層(ceng)膠(jiao)(jiao)(jiao)合(he)板(ban)(ban)(ban)(ban)(ban)；阻燃板(ban)(ban)(ban)(ban)(ban)是由木(mu)段旋(xuan)切成(cheng)單(dan)(dan)板(ban)(ban)(ban)(ban)(ban)或(huo)由木(mu)方刨切成(cheng)薄木(mu)，對(dui)單(dan)(dan)板(ban)(ban)(ban)(ban)(ban)進行阻燃處理后再用膠(jiao)(jiao)(jiao)粘劑膠(jiao)(jiao)(jiao)合(he)而成(cheng)的三層(ceng)或(huo)多(duo)層(ceng)的板(ban)(ban)(ban)(ban)(ban)狀材料。阻燃板(ban)(ban)(ban)(ban)(ban)和木(mu)工(gong)板(ban)(ban)(ban)(ban)(ban)的性(xing)質(zhi)不(bu)(bu)同、結構不(bu)(bu)同，防護性(xing)能(neng)也(ye)不(bu)(bu)同。
