防火桥架主要用于对防火要求高的环境，可以起到阻燃的作用。它的制造主要是指在托盘表面涂上一层防火涂料，那么如何起到防火的作用呢？

The fire-proof bridge is mainly used in the environment with high fire protection requirements, which can play the role of flame retardant. Its manufacturing mainly refers to coating a layer of fire retardant coating on the surface of the tray, so how to play the role of fire prevention?

防火桥架主要由玻璃纤维增强材料、无机胶粘复合防火板、金属骨架复合材料等防火基材制成。它由钢制成，内有双层防火盖板和无机防火槽盒。

The fireproof bridge is mainly made of glass fiber reinforced materials, inorganic adhesive composite fireproof boards, metal skeleton composite materials and other fireproof substrates. The utility model is made of steel and has a double-layer fireproof cover plate and an inorganic fireproof slot box.

保温层平均厚度25mm左右，双盖板通风散热，内部有防火涂料。防火桥架着火时，涂料膨胀，堵塞散热孔，保护槽盒内的电缆。无机防火线槽盒防火性能经固定60分钟检验，电缆无损伤。支架结构良好，能有效固定无机防火线槽盒。

The average thickness of the insulation layer is about 25mm, the double cover plate is ventilated and radiating, and the interior is provided with fireproof coating. When the fire-proof bridge is on fire, the coating expands, blocking the cooling holes and protecting the cables in the trough box. The fireproof performance of inorganic fireproof trunking box has been tested for 60 minutes, and the cable is not damaged. The support has good structure and can effectively fix the inorganic fireproof trunking box.

济南电缆桥架人员提醒您，实际上防火桥在防火时会膨胀发泡，遇火时涂料中含有的一些成分会发生反应，这是产生不燃性气体时的吸热反映。还消耗大量热量，可以减少系统温度，防火隔热突出。

Jinan cable bridge personnel remind you that in fact, the fire bridge will expand and foam during fire prevention, and some components contained in the coating will react in case of fire, which is an endothermic reflection when non combustible gas is generated. It also consumes a lot of heat, which can reduce the system temperature and highlight the fire prevention and insulation.

当防火桥架遇到火焰高温的作用时，涂层受热会分解出大量的惰性气体，减少可燃气体和氧气的浓度，减缓或窒息燃烧。遇火时，涂层会膨胀起泡，形成隔热涂层。

When the fire-proof bridge encounters the effect of high flame temperature, the coating will decompose a large amount of inert gas when heated, reducing the concentration of combustible gas and oxygen, and slowing down or suffocating the combustion. In case of fire, the coating will expand and bubble to form a thermal insulation coating.

发泡不仅会隔绝氧气，在高温下还会与钢铁基材产生很强的附着力，同时还具有好的隔热性。它的导热系数很低，延缓了热量向被保护的基材传递的速度，防止了钢结构直接受到火焰和高温的侵袭。因此，与大跨度电缆桥架相比，防火隔热显着。

Foaming can not only isolate oxygen, but also produce strong adhesion with steel substrate at high temperature. At the same time, it also has good heat insulation. Its thermal conductivity is very low, delaying the transfer of heat to the protected substrate and preventing the steel structure from being directly attacked by flame and high temperature. Therefore, compared with long-span cable tray, fire prevention and heat insulation are significant.
