　　防火門的要求是什么

　　What are the requirements for fire doors

　　防火門是用難燃木材或難燃木材制品作門框、門扇骨架、門扇面板，門扇內(nèi)若填充材料，則填充對人體無害的防火隔熱材料，并配以防火五金配件所組成的具有一定耐火性能的門。

　　Fireproof doors are doors made of fire-resistant wood or fire-resistant wood products as door frames, door leaf frames, and door leaf panels. If the door leaf is filled with materials, it is filled with non-toxic and harmless fire-resistant insulation materials for the human body, and equipped with fire-resistant hardware accessories to form a door with certain fire resistance performance.

　　門扇與門框的搭接尺寸不應(yīng)小于12mm ;門扇與門框有合頁一側(cè)的配合活動間隙不應(yīng)大于設(shè)計圖紙規(guī)定的尺寸公差；門扇與門框有鎖一側(cè)的配合活動間隙不應(yīng)大于設(shè)計圖紙規(guī)定的尺寸公差；門扇與上框的配合活動間隙不應(yīng)大于3mm ;雙扇、多扇門的門扇之間縫隙不應(yīng)大于3mm ;門扇與下框或地面的活動間隙不應(yīng)大于9mm ;門扇與門框貼合面間隙：門扇與門框有合頁一側(cè)、有鎖一側(cè)及上框的貼合面間隙均不應(yīng)大于3mm ;門扇與門框的平面高低差：在防火門開面上，天津伸縮條碼閱讀器門框與門扇的平面高低差不應(yīng)大于1mm。

　　The overlap size between the door leaf and the door frame should not be less than 12mm; The fitting clearance between the door leaf and the door frame on the hinge side should not exceed the dimensional tolerance specified in the design drawings; The clearance between the door leaf and the locked side of the door frame should not exceed the dimensional tolerance specified in the design drawings; The clearance between the door leaf and the upper frame should not exceed 3mm; The gap between the door leaves of double or multiple doors should not exceed 3mm; The clearance between the door leaf and the lower frame or ground should not exceed 9mm; The gap between the bonding surface of the door leaf and the door frame: The gap between the bonding surface of the door leaf and the door frame on the side with hinges, the side with locks, and the upper frame should not exceed 3mm; The height difference between the door leaf and the door frame: On the opening surface of the fire door, the height difference between the Tianjin telescopic barcode reader door frame and the door leaf should not exceed 1mm.

　　木質(zhì)防火門是指用木材或木材制品制作門框、門扇骨架、門扇面板，耐火極限達到規(guī)定的門。木質(zhì)防火門之間的一些小的偏差是不能錯的，也許就是一個小小的細節(jié)問題，就可能達不到的標準。

　　Wooden fireproof doors refer to doors made of wood or wood products, such as door frames, door leaf frames, and door leaf panels, with a fire resistance limit that meets national regulations. Some small deviations between wooden fireproof doors cannot be mistaken, perhaps just a small detail issue, which may not meet the national standards.

　　使用材料

　　Using materials

　　比較一下使用材料，防火門結(jié)構(gòu)簡單，主要由四部分組成：閉門器、門板的材料（有06和08等幾種）、門框材料、防火板組成。防火門一般采用質(zhì)量較好的08材料，正常使用壽命在5-8年間，門板的鐵材較厚，同樣厚度的防火門，防火門的重量要大于乙級防火門。

　　Firstly, let's compare the materials used. Fire doors have a simple structure and mainly consist of four parts: door closers, door panel materials (including 06 and 08), door frame materials, and fire panels. Class A fire doors generally use high-quality 08 materials with a normal service life of 5-8 years. The iron material of the door panel is thicker, and for fire doors of the same thickness, the weight of Class A fire doors is greater than that of Class B fire doors.

　　防火時間

　　Fire prevention time

　　防火門的防火時間主要由防火板決定，在這方面，防火門采用的防火板一般比乙級防火門采用的防火板的性能要好，因此整體性能要強于乙級防火門。此外，防火門尤其適用于那些要求電鍍前細磨、振動出色、手工具鏡面拋光、電熱管鏡面拋光等場合，如各類家私五金配件的振光、手工具的切削拋光、日用產(chǎn)品、自行畫配件的表面振光等。

　　The fire prevention time of fire doors is mainly determined by the fire prevention board. In this regard, the fire prevention board used for Class A fire doors generally has better performance than the fire prevention board used for Class B fire doors, so the overall performance is stronger than that of Class B fire doors. In addition, Class A fireproof doors are particularly suitable for occasions that require fine grinding before electroplating, excellent vibration, mirror polishing of hand tools, mirror polishing of electric heating tubes, etc., such as vibration polishing of various furniture hardware accessories, cutting polishing of hand tools, surface vibration polishing of daily products, and self painted accessories.

　　還有一點值的關(guān)注的是，防火門中帶門框功能的材料，因為其門框的規(guī)格可以根椐客戶的需要進行靈活的訂制，設(shè)計門洞尺寸時更為方便、省力、省時。

　　Another noteworthy point is that materials with door frame function in Class A fireproof doors can be flexibly customized according to customer needs, making door opening size design more convenient, labor-saving, and time-saving.

　　使用成本

　　Cost of use

　　雖然從采購成本來講，防火門要高于乙級防火門，但從綜合的使用成本上來講，防火門在很多方面要優(yōu)于乙級防火門。但是，乙級防火門也有價廉的特點，也占據(jù)一部分低端市場。

　　Although in terms of procurement cost, Class A fire doors are higher than Class B fire doors, in terms of comprehensive usage cost, Class A fire doors are superior to Class B fire doors in many aspects. However, Class B fire doors also have the characteristic of being affordable and occupy a portion of the low-end market.

　　巧婦難為無米之炊，米也分好米和壞米，廠家不肯用"好米"，自然生產(chǎn)不出質(zhì)量可靠的防火門，這點值得企業(yè)思考。

　　A clever woman cannot cook without rice, and rice can also be divided into good and bad rice. Manufacturers refuse to use "good rice", and naturally cannot produce high-quality and reliable fire doors. This is worth considering for enterprises.
