　　21世纪，人们对于家庭的防火安全越来越重视了，所以各种防火门也纷纷面市，那么大家了解防火门填充材料选择有何讲究吗？防火门填充材料的作用是什么呢？

　　In twenty-first Century, people for the family to pay more and more attention to fire safety, so all kinds of fire doors are available, then you know the fire door filling material is pay attention to what? What is the role of fire door filling material?

　　一、防火门填充材料的作用

　　A, fire door filling material role

　　防火门填充材料在防火门的耐火隔热性能中起到主要作用，因此防火门填充材料是防火门工程检查和验收的重点项目。选择防火门要选择那些能公司自己能生产无机不燃门芯材料的公司，这样质量上有保证，因为主要性能的质量得到有效保证。

　　Fire door filling materials in fire doors fire insulation performance plays a major role, so fire door filling material is fire door engineering inspection and acceptance of key projects. Choose fire doors to choose those companies can produce their own inorganic non combustible door core materials companies, such quality assurance, because the main performance of the quality is effectively guaranteed.

　　在一定温度下添加引发剂聚合成一定分子量的丙烯酰胺粘稠液体，溶液中添加其它无机耐火材料。将此透明溶液灌入玻璃夹层中，一定时间后丙烯酰胺产生交联，形成网状结构成为透明状、热固性、胶冻状物质，该防火门物质遇火后形成致密的耐火炭层，起到防火隔热的作用。

　　A certain molecular weight acrylamide viscous liquid was synthesized by adding initiators at certain temperature, and other inorganic refractories were added in the solution. This solution is poured into the transparent glass interlayer, after a certain time of the acrylamide formed reticular structure become cross-linked, transparent, thermosetting, jelly like material, the fire door fire after the formation of refractory material compact carbon layer, to the effect of fire insulation.

　　因此，防火门的质量直接影响到防火玻璃产品的耐火性能。对于膨胀性防火密封件的质量有几种简易的鉴定方法，目测样品应该平整;样品中的黑色颗粒应该在20左右;防火门使用打火机烧时，样品膨胀性能明显，同时炭粒不应该呈飞絮状。

　　Therefore, the quality of fire door directly affects the fire resistance of fire-resistant glass products. There are several simple identification methods for quality of fire expansion seal, visual samples should be smooth; black particles in the sample should be around 20; the fire door use the lighter to burn, sample expansion performance significantly, while the carbon particles should not be like flying.

　　二、防火门填充材料选择有何讲究

　　Two, fire door filling material selection what pay attention to

　　通常防火门会在人流物流较多的疏散通道上应用到。难燃防火门木质材料或难燃木材制品制作门框、门扇骨架、防火门门扇面板。

　　Usually fire door will be in the stream of people more logistics evacuation channel application. Flame retardant fire door wood or burning wood products making door frame and door frame, fire door panel.

　　防火门应填充对人体无毒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内置防火闭门器等，当一些大型建设方对防火门有防盗等管理上的要求时应由电气专业配合设计。

　　Fire doors should be filled with insulation materials non-toxic and harmless to the human body, and the fire door built with certain refractory properties to fireproof hardware fittings made of door closers, when some large building there are security management requirements of fire door should be professional with the electrical design.

　　防火门可以尽可能全面的降低安全隐患。而对于常开，快速闭锁、遇火灾快速开启等环境，必须由电气专业提供自控设计。

　　Fire doors can be as comprehensive as possible to reduce security risks. For the normally open, fast closedown, fire quickly open environment, must be provided by the electrical professional self-control design.
