防火橋架主要用于對防火要求高的環(huán)境，可以起到阻燃的作用。它的制造主要是指在托盤表面涂上一層防火涂料，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?

防火橋架主要由玻璃纖維增強(qiáng)材料、無機(jī)膠粘復(fù)合防火板、金屬骨架復(fù)合材料等防火基材制成。它由鋼制成，內(nèi)有雙層防火蓋板和無機(jī)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.

保溫層平均厚度25mm左右，雙蓋板通風(fēng)散熱，內(nèi)部有防火涂料。防火橋架著火時，涂料膨脹，堵塞散熱孔，保護(hù)槽盒內(nèi)的電纜。無機(jī)防火線槽盒防火性能經(jīng)固定60分鐘檢驗，電纜無損傷。支架結(jié)構(gòu)良好，能有效固定無機(jī)防火線槽盒。

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.

濟(jì)南電纜橋架人員提醒您，實際上防火橋在防火時會膨脹發(fā)泡，遇火時涂料中含有的一些成分會發(fā)生反應(yīng)，這是產(chǎn)生不燃性氣體時的吸熱反映。還消耗大量熱量，可以減少系統(tǒng)溫度，防火隔熱突出。

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.

當(dāng)防火橋架遇到火焰高溫的作用時，涂層受熱會分解出大量的惰性氣體，減少可燃?xì)怏w和氧氣的濃度，減緩或窒息燃燒。遇火時，涂層會膨脹起泡，形成隔熱涂層。

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.

發(fā)泡不僅會隔絕氧氣，在高溫下還會與鋼鐵基材產(chǎn)生良好的附著力，同時還具有好的隔熱性。它的導(dǎo)熱系數(shù)很低，延緩了熱量向被保護(hù)的基材傳遞的速度，防止了鋼結(jié)構(gòu)直接受到火焰和高溫的侵襲。因此，與大跨度電纜橋架相比，防火隔熱顯著。

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.

電纜橋架是防火的，但是如果在防火要求高的環(huán)境中，就需要使用。所以您在實際使用之前還是要多了解相關(guān)內(nèi)容，關(guān)注我們網(wǎng)站m.ymmgjx.net為您推送更多信息！
