你真正了解大連卷簾門門嗎？

　　Do you truly understand Dalian rolling shutter doors?

　　根據(jù)相關(guān)的規(guī)定，防火門所用木材應(yīng)為阻燃木材或用防火板包裹的復(fù)合材，并達(dá)到標(biāo)準(zhǔn)的難燃性要求。目前國內(nèi)木材阻燃處理一般是在一定溫度、壓力下金屬儲罐中用含磷、氮等的水性阻燃劑進(jìn)行木材浸泡處理，使阻燃劑滲透到木材內(nèi)部≥5mm處，然后烘干，再根據(jù)實(shí)際尺寸對木材表面進(jìn)行刨平和細(xì)加工。為了透光和美觀，大多數(shù)防火門裝有玻璃窗，按照GB12955-2008規(guī)定，國標(biāo)的是（200*600）玻璃窗。具有耐火隔熱性能的防火玻璃一般為夾層玻璃，兩層玻璃中間是防火膠。防火膠一般由丙烯酰胺水溶液在一定溫度下添加引發(fā)劑聚合成一定分子量的丙烯酰胺粘稠液體，溶液中添加其它無機(jī)耐火材料。

　　According to relevant national regulations, the wood used for fire doors should be flame-retardant wood or composite material wrapped with fireproof boards, and meet the standard flame retardant requirements. At present, the flame retardant treatment of wood in China is generally carried out by soaking the wood in metal storage tanks under certain temperature and pressure with water-based flame retardants containing phosphorus, nitrogen, etc., so that the flame retardant penetrates into the interior of the wood by ≥ 5mm, then drying, and finally planing and fine processing the surface of the wood according to the actual size. For the sake of transparency and aesthetics, most fire doors are equipped with glass windows. According to GB12955-2008, the national standard is (200 * 600) glass windows. Fireproof glass with fire-resistant and thermal insulation properties is generally laminated glass, with fire-resistant adhesive between the two layers of glass. Fireproof adhesive is generally synthesized by adding an initiator to an acrylamide aqueous solution at a certain temperature to form a viscous liquid of acrylamide with a certain molecular weight. Other inorganic refractory materials are added to the solution.

　　卷簾門門中必不可少的其他五金配件有閉門器、防火鎖、防火鉸鏈、插銷等，其中防火鎖、防火鉸鏈、插銷只要滿足設(shè)計(jì)要求，其日常使用較少，而閉門器、開關(guān)順序器有可能因?yàn)槭褂貌划?dāng)造成損壞。防火門不是擺設(shè)，不要在發(fā)生火災(zāi)的時(shí)候才會想起， 據(jù)了解，目前多數(shù)防火門不是因年久失修損壞失去防火作用就是被鎖起來或是撤掉、堆積物品。殊不知，一旦失火，后果不甚設(shè)想，特別是、市場、大樓等人流密集的地方。劃分防火分區(qū)，控制分區(qū)建筑面積所設(shè)防火墻和防火隔墻上的門。當(dāng)建筑物設(shè)置防火墻或防火門有困難時(shí)，要用卷簾門門代替，同時(shí)須用水幕保護(hù)。

　　Other essential hardware accessories in rolling shutter doors include door closers, fireproof locks, fireproof hinges, and locking pins. Among them, fireproof locks, fireproof hinges, and locking pins are less commonly used as long as they meet design requirements, while door closers and switch sequencers may be damaged due to improper use. Fire doors are not just decorations. Don't only think about them when a fire occurs. It is understood that most fire doors currently lose their fire protection function due to long-term disrepair, damage, or being locked, removed, or piled up with items. Little do they know that once a fire breaks out, the consequences are unimaginable, especially in crowded places such as shopping malls, markets, and buildings. Divide fire zones and control the fire walls and doors on the fire partition walls set up to control the building area of the zones. When it is difficult to install firewalls or fire doors in buildings, rolling shutter doors should be used instead, and water curtains should be used for protection.
