　　防火门的要求是什么

　　What are the requirements for fire doors

　　防火门是用难燃木材或难燃木材制品作门框、门扇骨架、门扇面板，门扇内若填充材料，则填充对人体无害的防火隔热材料，并配以防火五金配件所组成的具有一定耐火性能的门。

　　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.

　　门扇与门框的搭接尺寸不应小于12mm ;门扇与门框有合页一侧的配合活动间隙不应大于设计图纸规定的尺寸公差；门扇与门框有锁一侧的配合活动间隙不应大于设计图纸规定的尺寸公差；门扇与上框的配合活动间隙不应大于3mm ;双扇、多扇门的门扇之间缝隙不应大于3mm ;门扇与下框或地面的活动间隙不应大于9mm ;门扇与门框贴合面间隙：门扇与门框有合页一侧、有锁一侧及上框的贴合面间隙均不应大于3mm ;门扇与门框的平面高低差：在防火门开面上，天津伸缩条码阅读器门框与门扇的平面高低差不应大于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.

　　木质防火门是指用木材或木材制品制作门框、门扇骨架、门扇面板，耐火极限达到规定的门。木质防火门之间的一些小的偏差是不能错的，也许就是一个小小的细节问题，就可能达不到的标准。

　　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

　　比较一下使用材料，防火门结构简单，主要由四部分组成：闭门器、门板的材料（有06和08等几种）、门框材料、防火板组成。防火门一般采用质量较好的08材料，正常使用寿命在5-8年间，门板的铁材较厚，同样厚度的防火门，防火门的重量要大于乙级防火门。

　　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.

　　防火时间

　　Fire prevention time

　　防火门的防火时间主要由防火板决定，在这方面，防火门采用的防火板一般比乙级防火门采用的防火板的性能要好，因此整体性能要强于乙级防火门。此外，防火门尤其适用于那些要求电镀前细磨、振动出色、手工具镜面抛光、电热管镜面抛光等场合，如各类家私五金配件的振光、手工具的切削抛光、日用产品、自行画配件的表面振光等。

　　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.

　　还有一点值的关注的是，防火门中带门框功能的材料，因为其门框的规格可以根椐客户的需要进行灵活的订制，设计门洞尺寸时更为方便、省力、省时。

　　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

　　虽然从采购成本来讲，防火门要高于乙级防火门，但从综合的使用成本上来讲，防火门在很多方面要优于乙级防火门。但是，乙级防火门也有价廉的特点，也占据一部分低端市场。

　　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.

　　巧妇难为无米之炊，米也分好米和坏米，厂家不肯用"好米"，自然生产不出质量可靠的防火门，这点值得企业思考。

　　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.
