告訴你(ni)阻(zu)燃(ran)(ran)(ran)(ran)舞(wu)臺(tai)(tai)幕(mu)布(bu)設(she)計及重(zhong)要性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，在選(xuan)用(yong)舞(wu)臺(tai)(tai)建筑構件和建筑材(cai)(cai)料必須(xu)(xu)具有(you)防(fang)火性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)必須(xu)(xu)必須(xu)(xu)符合國家(jia)標準或者行業標準，阻(zu)燃(ran)(ran)(ran)(ran)舞(wu)臺(tai)(tai)幕(mu)布(bu)必須(xu)(xu)是阻(zu)燃(ran)(ran)(ran)(ran)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)的。按照(zhao)我國規(gui)定，建筑裝修(xiu)材(cai)(cai)料的燃(ran)(ran)(ran)(ran)燒性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)分為4個等級(ji)(ji)。其中A級(ji)(ji)為不燃(ran)(ran)(ran)(ran)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，B1級(ji)(ji)為難燃(ran)(ran)(ran)(ran)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)。舞(wu)臺(tai)(tai)地(di)板(ban)及地(di)毯必須(xu)(xu)達到A級(ji)(ji)標準不燃(ran)(ran)(ran)(ran)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，能(neng)(neng)以往的舞(wu)臺(tai)(tai)幕(mu)布(bu)多(duo)為B3級(ji)(ji)，是具有(you)可燃(ran)(ran)(ran)(ran)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)的。凡是舞(wu)臺(tai)(tai)燈(deng)光照(zhao)明設(she)備烤(kao)著舞(wu)臺(tai)(tai)幕(mu)布(bu)發生的火災，其幕(mu)布(bu)的燃(ran)(ran)(ran)(ran)燒性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)都是B3級(ji)(ji)可燃(ran)(ran)(ran)(ran)的。《建筑內部(bu)裝修(xiu)設(she)計防(fang)火規(gui)范》規(gui)定：影院(yuan)、會堂(tang)、禮(li)堂(tang)、劇場(chang)、音樂廳，體(ti)育館所用(yong)的舞(wu)臺(tai)(tai)幕(mu)布(bu)(帷(wei)幕(mu))的燃(ran)(ran)(ran)(ran)燒性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)不能(neng)(neng)低于B1級(ji)(ji)，即應為阻(zu)燃(ran)(ran)(ran)(ran)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)織物。因(yin)此(ci)在檢查(cha)驗(yan)收這(zhe)(zhe)些場(chang)所的幕(mu)布(bu)的燃(ran)(ran)(ran)(ran)燒性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)屬(shu)于什么(me)等級(ji)(ji)時，應十分關(guan)注這(zhe)(zhe)些幕(mu)布(bu)是不是阻(zu)燃(ran)(ran)(ran)(ran)織物，有(you)無消(xiao)防(fang)機(ji)關(guan)檢驗(yan)合格的證書(shu)。

（一）：在阻(zu)燃(ran)舞(wu)臺幕(mu)布(bu)中(zhong)使(shi)用的(de)‘阻(zu)燃(ran)劑“它的(de)化學(xue)名(ming)稱是(shi)“氯化氨(an)”具(ju)有熱(re)不穩定(ding)性，受(shou)熱(re)易分解！在受(shou)熱(re)過(guo)程中(zhong)氯化氫和氨(an)氣的(de)化學(xue)反(fan)應吸收了大(da)量的(de)熱(re)，生成的(de)氣體還具(ju)有一定(ding)阻(zu)隔空氣的(de)作用！就算失火，也會減慢燃(ran)燒速度。

（二）：生產的舞(wu)(wu)臺(tai)幕(mu)(mu)布(bu)(bu)(bu)，在選料(liao)(liao)方面(mian)(mian)(mian)要(yao)考慮(lv)到舞(wu)(wu)臺(tai)音響的擴聲(sheng)、阻燃舞(wu)(wu)臺(tai)幕(mu)(mu)布(bu)(bu)(bu)的光效(xiao)。通常舞(wu)(wu)臺(tai)幕(mu)(mu)布(bu)(bu)(bu)面(mian)(mian)(mian)料(liao)(liao)選用具有亞光性能，幕(mu)(mu)布(bu)(bu)(bu)的顏色純(chun)正(zheng)，以及(ji)面(mian)(mian)(mian)料(liao)(liao)的柔(rou)軟性及(ji)垂感度，幕(mu)(mu)布(bu)(bu)(bu)柔(rou)軟度直(zhi)徑影響到幕(mu)(mu)布(bu)(bu)(bu)的垂感性，舞(wu)(wu)臺(tai)幕(mu)(mu)布(bu)(bu)(bu)在使用過程中應(ying)當起到拍照無反光點，色澤艷麗，靜電處理。面(mian)(mian)(mian)料(liao)(liao)的密度，面(mian)(mian)(mian)料(liao)(liao)的吸光度首(shou)先考慮(lv)。
