乙級(ji)(ji)(ji)防火(huo)(huo)(huo)門(men)(men)(men)是(shi)一種重要的(de)(de)(de)(de)(de)(de)安全設備，用(yong)(yong)(yong)(yong)(yong)于保(bao)(bao)護(hu)人們的(de)(de)(de)(de)(de)(de)生命(ming)和財產安全。它的(de)(de)(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽命(ming)是(shi)根據(ju)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)環(huan)境(jing)、維(wei)護(hu)保(bao)(bao)養等(deng)(deng)因素來(lai)決(jue)定(ding)(ding)的(de)(de)(de)(de)(de)(de)。一般(ban)來(lai)說，乙級(ji)(ji)(ji)防火(huo)(huo)(huo)門(men)(men)(men)的(de)(de)(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽命(ming)可以(yi)(yi)達到(dao)20年以(yi)(yi)上，但具(ju)體的(de)(de)(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽命(ming)還需要考(kao)慮以(yi)(yi)下(xia)幾個因素：1.使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)環(huan)境(jing)：乙級(ji)(ji)(ji)防火(huo)(huo)(huo)門(men)(men)(men)在(zai)不同(tong)的(de)(de)(de)(de)(de)(de)環(huan)境(jing)下(xia)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)(de)(de)(de)壽命(ming)也會(hui)有所不同(tong)。如果(guo)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)環(huan)境(jing)惡劣（例(li)如濕度(du)高、溫度(du)變化大等(deng)(deng)），則(ze)其(qi)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽命(ming)可能(neng)會(hui)縮短。2.維(wei)護(hu)保(bao)(bao)養：定(ding)(ding)期進行(xing)維(wei)護(hu)保(bao)(bao)養可以(yi)(yi)延(yan)長(chang)乙級(ji)(ji)(ji)防火(huo)(huo)(huo)門(men)(men)(men)的(de)(de)(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽命(ming)。例(li)如，不銹(xiu)鋼防火(huo)(huo)(huo)門(men)(men)(men)，定(ding)(ding)期檢查門(men)(men)(men)框、門(men)(men)(men)扇、鎖(suo)具(ju)等(deng)(deng)部(bu)件是(shi)否正常工(gong)作，及時更(geng)換磨(mo)損或(huo)損壞的(de)(de)(de)(de)(de)(de)部(bu)件，保(bao)(bao)持門(men)(men)(men)體干凈整潔等(deng)(deng)。3.使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)頻(pin)率：如果(guo)乙級(ji)(ji)(ji)防火(huo)(huo)(huo)門(men)(men)(men)被頻(pin)繁(fan)地開(kai)關，則(ze)其(qi)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽命(ming)可能(neng)會(hui)縮短。因此，常州防火(huo)(huo)(huo)門(men)(men)(men)，在(zai)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)過(guo)程中應(ying)盡量減少不必要的(de)(de)(de)(de)(de)(de)開(kai)關操作，避免對門(men)(men)(men)體造(zao)成過(guo)度(du)的(de)(de)(de)(de)(de)(de)磨(mo)損。總的(de)(de)(de)(de)(de)(de)來(lai)說，乙級(ji)(ji)(ji)防火(huo)(huo)(huo)門(men)(men)(men)的(de)(de)(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)壽命(ming)可以(yi)(yi)通過(guo)合理的(de)(de)(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)和維(wei)護(hu)來(lai)延(yan)長(chang)。同(tong)時，也需要注意選擇質(zhi)量可靠(kao)的(de)(de)(de)(de)(de)(de)產品，以(yi)(yi)保(bao)(bao)證(zheng)其(qi)在(zai)關鍵時刻能(neng)夠起(qi)到(dao)應(ying)有的(de)(de)(de)(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)。

玻璃防火(huo)門(men)的(de)保養周期可(ke)以(yi)根(gen)據實際情況而定(ding)，木質防火(huo)門(men)，一般來說，如(ru)果(guo)使(shi)用環(huan)境較好(hao)且日常維(wei)(wei)護得當的(de)話，可(ke)以(yi)使(shi)用5-8年左右。具體的(de)保養時間取決于門(men)的(de)使(shi)用頻率、環(huan)境的(de)濕度和(he)(he)清潔方法等(deng)因素。要(yao)保持(chi)其良好(hao)的(de)性(xing)能，需要(yao)定(ding)期進行適當的(de)擦(ca)拭(shi)和(he)(he)維(wei)(wei)護：建議每周清洗并開(kai)啟關(guan)(guan)閉一次使(shi)內部材料得到潤滑；每半年檢查一遍(bian)上下(xia)拉鎖是否順暢靈活可(ke)靠；每年至少清理過濾網1至2次以(yi)防堆積灰(hui)塵影響空氣流通及外觀效(xiao)果(guo)等(deng)。同時注意避免在有壓力(li)的(de)情況下(xia)強行關(guan)(guan)門(men)或開(kai)門(men)（如(ru)突然發現(xian)情況不(bu)妙應(ying)立即將正(zheng)在通過的(de)門(men)關(guan)(guan)上），這樣可(ke)以(yi)有效(xiao)地延長使(shi)用壽命以(yi)及保持(chi)良好(hao)的(de)運行狀態。。
