防火電纜橋架的構(gòu)造特性！
哪樣橋架具備優(yōu)良的阻燃性?自然，塑膠吐火橋。噴漆防火橋，通稱防火橋，表層原材料為熱浸鍍鋅和冷噴鋅，熱浸鍍鋅外型不冷噴鋅細(xì)致明亮，但熱鍍鋅層的薄厚是冷噴鋅層的幾十倍。耐腐蝕性也是鋅涂層的幾十倍。本商品適用10KV下列的電線電纜、變頻電纜、照明燈具走線等室內(nèi)室外架空電纜管溝、隧道施工。阻燃性橋關(guān)鍵分成三種種類：內(nèi)燃型、外阻燃性型和全阻燃性型。外阻燃性型為外抹一層防火材料，避免外阻燃性毀壞鋼橋架的沖擊韌性。適用火災(zāi)事故多發(fā)性場地。內(nèi)阻燃性型是槽體式或圓盤式電纜線橋，內(nèi)表層涂有防火材料或嵌入阻燃板。橋架常見于阻燃性擋板，即當(dāng)電纜線起火時，阻燃性段能夠限定打火電纜線的阻燃性長短。全阻燃性型是在內(nèi)外表層涂敷防火材料或嵌入阻燃板，可維護(hù)鋼橋的沖擊韌性，限定打火電纜線的長短。
Which cable tray has excellent flame retardancy? Natural, plastic spitting fire bridge. Spray painting fire safety bridge is commonly known as fire safety bridge. The surface raw materials are hot-dip galvanizing and cold spraying zinc. The appearance of hot-dip galvanizing is not cold spraying zinc, which is fine and bright, but the thickness of the hot-dip galvanizing layer is dozens of times that of the cold spraying zinc layer. Corrosion resistance is dozens of times of zinc coating. This commodity is applicable to the construction of indoor and outdoor overhead cable pipe trenches and tunnels for wires and cables below 10KV, frequency conversion cables, lighting fixture routing, etc. The flame retardant bridge is divided into three types: internal combustion type, external flame retardant type and full flame retardant type. The external flame retardant type is coated with a layer of fireproof material to prevent the external flame retardant from damaging the impact toughness of the steel bridge frame. It is applicable to sites with frequent fire accidents. The internal flame-retardant type is tray type or disc type cable bridge, and the inner surface layer is coated with fireproof materials or embedded with flame-retardant plates. Bridge is commonly used in flame retardant baffle, that is, when the cable is on fire, the flame retardant section can limit the flame retardant length of the ignited cable. The full flame-retardant type is coated with fire-retardant materials or embedded with fire-retardant plates on the inner and outer surfaces, which can maintain the impact toughness of the steel bridge and limit the length of the ignition cable.
防火電纜橋架的構(gòu)造和特性以下：
The structure and characteristics of fireproof cable tray are as follows:
防火板材是以硅質(zhì)的原材料和石灰質(zhì)原材料為關(guān)鍵原材料，選用yx的高壓反應(yīng)釜技術(shù)性，摻加一定占比的紡織材料、質(zhì)輕石料、粘接劑和有機(jī)化學(xué)防腐劑做成的。防火板材是以硅質(zhì)的原材料和蛋白質(zhì)原材料為關(guān)鍵原材料，用一定占比的化學(xué)纖維生產(chǎn)加工而成。橫截面樣子勻稱，無彎折、歪曲、裂開、邊沿等缺點(diǎn)。
Fireproof board is made of siliceous raw materials and calcareous raw materials as the key raw materials, using yx autoclave technology, adding a certain proportion of textile materials, light stones, adhesives and organic chemical preservatives. Fireproof board is made of silica raw materials and protein raw materials as the key raw materials, and is produced and processed with a certain proportion of chemical fibers. The cross section shall be symmetrical without bending, distortion, cracking, edge and other defects.
