防(fang)(fang)(fang)火(huo)門(men)(men)板(ban)廣泛應用(yong)于(yu)建(jian)筑行業，可以(yi)分為(wei)室(shi)內(nei)防(fang)(fang)(fang)火(huo)門(men)(men)和室(shi)外防(fang)(fang)(fang)火(huo)門(men)(men)。室(shi)內(nei)防(fang)(fang)(fang)火(huo)門(men)(men)主要用(yong)于(yu)住宅、酒店(dian)、商(shang)場(chang)等(deng)公共場(chang)所的(de)防(fang)(fang)(fang)火(huo)隔(ge)斷，如(ru)電梯井(jing)、樓梯間、疏(shu)散通道(dao)等(deng)；室(shi)外防(fang)(fang)(fang)火(huo)門(men)(men)則常用(yong)于(yu)工廠、倉(cang)庫等(deng)建(jian)筑的(de)出(chu)入(ru)口(kou)處，以(yi)防(fang)(fang)(fang)止火(huo)災蔓延到(dao)其他區域。此外，防(fang)(fang)(fang)火(huo)門(men)(men)板(ban)還可以(yi)用(yong)于(yu)隧道(dao)、地(di)鐵站等(deng)地(di)下設(she)施的(de)防(fang)(fang)(fang)火(huo)隔(ge)離(li)。

乙(yi)(yi)級防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)是(shi)一(yi)種重要(yao)(yao)的(de)(de)(de)安(an)全設備，用(yong)(yong)(yong)(yong)(yong)于(yu)保護(hu)(hu)人(ren)們的(de)(de)(de)生命(ming)(ming)和(he)財(cai)產(chan)安(an)全。它的(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)是(shi)根據(ju)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)環境、維(wei)護(hu)(hu)保養(yang)等(deng)因(yin)素(su)(su)來決定的(de)(de)(de)。一(yi)般來說，乙(yi)(yi)級防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)的(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)可以(yi)達到20年以(yi)上，但具體(ti)的(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)還需要(yao)(yao)考慮(lv)以(yi)下幾個因(yin)素(su)(su)：1.使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)環境：乙(yi)(yi)級防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)在(zai)不(bu)(bu)同的(de)(de)(de)環境下使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)壽(shou)命(ming)(ming)也會有所不(bu)(bu)同。如(ru)果使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)環境惡劣（例如(ru)濕度(du)高、溫(wen)度(du)變化大等(deng)），則其使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)可能會縮短。2.維(wei)護(hu)(hu)保養(yang)：定期進行維(wei)護(hu)(hu)保養(yang)可以(yi)延長乙(yi)(yi)級防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)的(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)。例如(ru)，定期檢查(cha)門(men)(men)(men)(men)(men)框、門(men)(men)(men)(men)(men)扇、鎖具等(deng)部(bu)件(jian)是(shi)否正常工作，不(bu)(bu)銹鋼(gang)玻璃(li)防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)定制，及時(shi)更換磨損(sun)或損(sun)壞的(de)(de)(de)部(bu)件(jian)，保持門(men)(men)(men)(men)(men)體(ti)干(gan)凈整潔等(deng)。3.使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)頻(pin)率(lv)：如(ru)果乙(yi)(yi)級防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)被頻(pin)繁(fan)地開(kai)關，不(bu)(bu)銹鋼(gang)玻璃(li)防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)廠家，則其使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)可能會縮短。因(yin)此(ci)，在(zai)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)過程中應盡(jin)量(liang)減少不(bu)(bu)必(bi)要(yao)(yao)的(de)(de)(de)開(kai)關操作，不(bu)(bu)銹鋼(gang)玻璃(li)防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)價(jia)格，避免(mian)對門(men)(men)(men)(men)(men)體(ti)造成過度(du)的(de)(de)(de)磨損(sun)。總(zong)的(de)(de)(de)來說，乙(yi)(yi)級防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)的(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)可以(yi)通過合理的(de)(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)和(he)維(wei)護(hu)(hu)來延長。同時(shi)，馬(ma)鞍山不(bu)(bu)銹鋼(gang)玻璃(li)防(fang)(fang)火(huo)(huo)(huo)門(men)(men)(men)(men)(men)，也需要(yao)(yao)注意(yi)選擇質(zhi)量(liang)可靠的(de)(de)(de)產(chan)品，以(yi)保證其在(zai)關鍵時(shi)刻能夠起到應有的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)。

玻璃防火門(men)的(de)(de)(de)保養周(zhou)期可(ke)(ke)以(yi)(yi)(yi)根據實際情況而定(ding)，一(yi)般(ban)來(lai)說，如(ru)果(guo)使用(yong)環(huan)境(jing)(jing)較好(hao)(hao)且日(ri)常維護得(de)當(dang)的(de)(de)(de)話，可(ke)(ke)以(yi)(yi)(yi)使用(yong)5-8年左(zuo)右。具體(ti)的(de)(de)(de)保養時間取決于(yu)門(men)的(de)(de)(de)使用(yong)頻率、環(huan)境(jing)(jing)的(de)(de)(de)濕度和(he)清潔(jie)方(fang)法等因素。要保持其良好(hao)(hao)的(de)(de)(de)性(xing)能，需(xu)要定(ding)期進行(xing)適(shi)當(dang)的(de)(de)(de)擦(ca)拭和(he)維護：建議每周(zhou)清洗(xi)并開(kai)啟關(guan)閉一(yi)次使內部材(cai)料得(de)到潤滑；每半年檢查一(yi)遍(bian)上下拉鎖是否順暢(chang)靈活可(ke)(ke)靠；每年至少(shao)清理(li)過濾網1至2次以(yi)(yi)(yi)防堆積灰塵(chen)影響空氣流通(tong)及外觀效(xiao)果(guo)等。同(tong)時注意避免(mian)在有壓力(li)的(de)(de)(de)情況下強行(xing)關(guan)門(men)或開(kai)門(men)（如(ru)突然發現情況不妙應立即(ji)將(jiang)正(zheng)在通(tong)過的(de)(de)(de)門(men)關(guan)上），這樣可(ke)(ke)以(yi)(yi)(yi)有效(xiao)地延長使用(yong)壽命以(yi)(yi)(yi)及保持良好(hao)(hao)的(de)(de)(de)運行(xing)狀態。。
