木質(zhì)防火門：用難燃木材或難燃木材制品做門框、門扇骨架、門扇面板。木質(zhì)材料在經(jīng)過阻燃處理后完全可以達(dá)到阻燃標(biāo)準(zhǔn)。貼面處理：即在木材表面貼上一層具有阻燃性能的材料，以達(dá)到阻燃目的。表面處理：一般為在木材表面涂抹阻燃涂料，來達(dá)到一定的阻燃目的，常見的有密封性油漆，還一類是能產(chǎn)生膨脹性氣體的涂料，與門窗縫隙的防火密封膠條性能類同。深層處理：通過一定的方式使阻燃物質(zhì)與木質(zhì)材料滲透結(jié)合，以達(dá)到強(qiáng)有效的阻燃效果，常見為浸漬法和浸注法，防火門材料必須經(jīng)過深層次阻燃處理。根據(jù)其木質(zhì)材料不同防火門的阻燃處理手法繁簡不一。對(duì)于滲透性能良好的木材常壓浸漬法就能達(dá)到阻燃標(biāo)準(zhǔn)，對(duì)于滲透性能并非良好的木材可采用加壓的方式或多次處理，以達(dá)到阻燃標(biāo)準(zhǔn)。 </p><p style="text-indent:25px">根據(jù)發(fā)生耐火極限時(shí)間的不同，木質(zhì)防火門和鋼質(zhì)防火門分別劃分出三個(gè)防火門級(jí)別，甲級(jí)防火門(耐火極限)，乙級(jí)防火門(耐火極限)和丙級(jí)防火門(耐火極限)。木質(zhì)防火門和鋼質(zhì)防火門那種更好雖然說兩種門都可達(dá)到一定耐火極限時(shí)間標(biāo)準(zhǔn)，但因?yàn)椴馁|(zhì)的原因在發(fā)生火災(zāi)時(shí)，鋼質(zhì)防火門的燃燒完整性，穩(wěn)定性會(huì)更加出色。不過在按小時(shí)計(jì)算的耐火時(shí)間前提下，火場人員疏散所能使用耗費(fèi)的時(shí)一般情況下完全可以滿足，所以在選擇木質(zhì)防火門和鋼質(zhì)防火門時(shí)更多的是以日常實(shí)際使用為選擇目標(biāo)，通常來說，建筑物內(nèi)部主要以木質(zhì)防火門為主，外部配置鋼質(zhì)防火門更多。后記，木質(zhì)防火門和鋼質(zhì)防火門的區(qū)別還是非常大的。浙江程程消防設(shè)備有限公司是一家專業(yè)提供防火門設(shè)備的公司，期待您的光臨！</p><div
