冷鍍鋅槽式電纜橋架的防火作用
Fireproof trough cable tray is made of galvanized trough bridge after processing surface treatment production fireproof coating layer and a surface touch will have a rough slanting feeling, when the fire will not burn, and can block the further spread of the fire down, play a certain role of fire, and the use of high environmental protection paint makes fire the bridge on the coating has no toxicity, no pollution, fire resistance, water resistance, oil resistance. The performance... Generally used for laying: power cables, communication signals, cables, etc..
防火橋架是在普通橋架表面噴涂一層防火漆,以起到防火阻燃的作用!其實橋架本身并不會著火,著火的只可能是電纜,防火漆所起到的防火阻燃原理
The fireproof bridge is sprayed with a fireproof paint on the surface of the ordinary bridge frame, so as to play the role of fire prevention and flame retardance! In fact, the bridge itself does not fire, fire may only be cable, fire retardant fire retardant principle
熱鍍鋅是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層,從而使基體和鍍層二者相結(jié)合。熱鍍鋅具有鍍層均勻,附著力強,使用壽命長等優(yōu)點。
Hot galvanizing is to produce molten metal and iron matrix reaction and produce alloy layer, so that the substrate and coating two combination. Hot galvanizing has the advantages of uniform coating, strong adhesion, long service life and so on.
冷鍍鋅就是電鍍鋅,其本身的耐腐蝕性比熱鍍鋅相差很多。也相對便宜一些。
Cold galvanizing is zinc plating, and its corrosion resistance is much different from that of galvanized iron. The price is relatively cheaper.
鍍鋅成品的區(qū)別:熱鍍鋅外表沒有冷鍍鋅細(xì)膩光亮,但鋅層厚度方面熱鍍鋅是冷鍍鋅的幾十倍。防腐蝕性能也是電鍍鋅的幾十倍。
The difference between galvanized products: hot galvanized surface is not cold galvanized, delicate and bright, but the thickness of zinc coating, hot galvanizing is cold galvanized dozens of times. Corrosion resistance is also tens of times zinc plating.
阻燃防火橋架適用于10KV以下電力電纜,以及控制電纜、照明配線等室內(nèi)室外架空電纜溝、隧道的敷設(shè)。阻燃型橋架分為內(nèi)阻燃型、外阻燃型及全阻燃型。
The flame retardant fireproof bridge is suitable for laying power cables, power cables, lighting wiring, indoor and outdoor aerial cable trench and tunnel laying under 10KV. Flame retardant bridge is divided into internal combustion, flame retardant, and flame retardant type.
內(nèi)阻燃型是在槽式或托盤式電纜橋架和內(nèi)表面涂覆阻燃材料或鑲嵌阻燃板,常用于阻燃隔斷,即當(dāng)電纜著火時,由于阻燃段的作用,可限制著火電纜的延燃長度。
The internal resistance of combustion type is in the groove type or tray type cable tray and inner surface coated flame-retardant materials or embedded flame retardant board, commonly used in flame retardant partition, namely when the cable is on fire, because the fire retardant section, the length of delay can limit the fuel ignition cable.
