防火(huo)(huo)(huo)模塊一般以(yi)無機材料為基礎，添(tian)加了膨脹(zhang)性阻(zu)燃劑(ji)和樹脂類(lei)(lei)膠黏劑(ji)，經模具壓制(zhi)后制(zhi)成膨脹(zhang)型阻(zu)火(huo)(huo)(huo)模塊。此類(lei)(lei)不含(han)鹵族元素、石(shi)棉(mian)等物(wu)質(zhi)，不會(hui)揮發(fa)有害氣(qi)體。遇火(huo)(huo)(huo)時所(suo)含(han)有的(de)阻(zu)燃劑(ji)會(hui)迅速膨脹(zhang)，將電(dian)(dian)(dian)纜(lan)(lan)燒(shao)蝕后產生(sheng)的(de)空隙(xi)填充起來(lai)，防止(zhi)煙火(huo)(huo)(huo)蔓延串(chuan)燒(shao)。阻(zu)火(huo)(huo)(huo)模塊具有重(zhong)量輕(qing)、強度高、不會(hui)破損(sun)坍塌、隔熱效(xiao)果好、施工簡單(dan)、使用(yong)方(fang)便等特(te)點，是(shi)阻(zu)火(huo)(huo)(huo)包的(de)升級替代產品(pin)。其同時還具有耐水、耐油、耐腐蝕，使用(yong)壽命長等特(te)點。地鐵隧道區間內大(da)量電(dian)(dian)(dian)纜(lan)(lan)穿行，與電(dian)(dian)(dian)纜(lan)(lan)隧道相類(lei)(lei)，按國家有關規(gui)定，每隔100或(huo)200米，特(te)別(bie)是(shi)電(dian)(dian)(dian)纜(lan)(lan)接頭處，應(ying)設阻(zu)火(huo)(huo)(huo)隔斷。但由于傳統材料在(zai)(zai)技(ji)術性能及施工工藝上難以(yi)解決(jue)，故(gu)目前所(suo)有地鐵均沒有在(zai)(zai)隧道內設電(dian)(dian)(dian)纜(lan)(lan)阻(zu)火(huo)(huo)(huo)隔斷，留下電(dian)(dian)(dian)纜(lan)(lan)蔓延串(chuan)燒(shao)的(de)隱(yin)患(huan)。
