​如何防止钢制防火门受热变形？

钢质防火门具有重量轻、强度高、范围大、空间大、抗震性强等特点，在现代建筑行业广泛应用，钢防火门虽然是不燃材料，但在高温火灾中依然变形。如何防止钢铁防火门受热变形？我会让青海防火门制造企业的职员去找的。

Steel fire door with light weight, high strength, large scope, large space, strong earthquake resistance other characteristics, widely used in the modern construction industry, although steel fire door is non-combustible material, but still deformation in high temperature fire. How to prevent steel fire doors being deformed by heat? I will ask the staff of qinghai fire door manufacturer to find it.

1.外包层。在钢结构的外部增加外层可以现场浇铸或喷涂。现浇实心混凝土外层通常由钢丝网或钢筋制成，以增加强度并防止破裂。喷涂方法可将石灰水泥或石膏砂浆现场施用于钢结构表面，并与珍珠岩或石棉混合。同时，外壳也可以由珍珠岩，石棉，石膏或石棉水泥以及轻质混凝土制成预制板，并通过粘合剂，钉子，螺栓等将其固定在钢结构上。

1. Outsourcing layer. The outer layer of the steel structure can be cast sprayed on site. The outer layer of cast-in-place solid concrete is usually made of wire mesh steel reinforcement to increase strength prevent cracking. Spray method Lime cement gypsum mortar can be applied on the surface of steel structure mixed with perlite asbestos. Also, the shell can be made perlite, asbestos, gypsum asbestos-cement, light concrete prefabricated panels, which are fixed to the steel structure by adhesives, nails, bolts, etc.

2.充水。中空钢结构可以充满水以有效地防火。通过水在钢结构中的循环，可以吸收产生的热量使钢结构保持低温，冷却后的热水可以循环使用。

2. Water filling. Hollow steel structures can be filled with water to prevent fire effectively. Through the circulation of water in the steel structure, the heat generated can be absorbed to keep the steel structure at low temperature, the cooled hot water can be recycled.

3.屏蔽。钢结构设置在由耐火材料组成的墙壁或天花板中，钢制防火门可以通过添加少量耐火材料甚至不增加耐火材料来达到防火的目的。

3. The shielding. The steel structure is provided in the wall ceiling composed of refractory materials. The steel fire doors can be fireproof by adding a small amount of refractory materials even no refractory materials.

4.防火涂料。钢结构阻燃涂料具有良好的防火，隔热性能，施工不受钢结构的几何形状的限制，一般不需要添加辅助设施，该涂料质量轻，具有一定的审美装饰效果。相比之下，直接喷涂在钢部件上耐火涂层特别实用，简单，方便；

4. Fireproof paint. Steel structure flame retardant coating has good fire prevention, heat insulation performance, construction is limited by the geometric shape of steel structure, generally do need to add auxiliary facilities, the quality of the paint is light, has a certain aesthetic decorative effect. In contrast, direct spraying refractory coating on steel components is particularly practical, simple convenient;

如何防止钢制防火门受热变形？通过以上分享，相信每个人都有基本的了解。防火原理钢结构主要通过拦截和疏ging来防火。设置阻挡火焰或高温的屏障，以防止其接触钢部件；通过吸热材料将传递给钢的热量传递出去；使用绝缘材料来保护钢部件以阻止外部热传递。另外，请关注西宁防火卷帘门厂家的官方网站，以了解更多关于青海防火门厂家产品的信息。您可以直接联系在线客服或留言，我们将竭诚为您提供更好的服务！
