防火電纜橋架一般會在表面噴涂防火漆

防火電纜橋架一般表面噴涂的是防火漆。
Generally, the surface of fireproof cable tray is sprayed with fireproof paint.
防火漆是由環(huán)氧樹脂植物油酸酯化后,別離與氧化鐵紅、氧化鐵黑、鋅黃等顏料和體質顏料研磨,并加入催干劑,以、丁醇調制而成。
Fire retardant paint is prepared by esterification of epoxy resin with vegetable oleic acid, grinding with iron oxide red, iron oxide black, zinc yellow and other pigments and physical pigments, adding desiccant and butanol.
防火漆漆膜堅硬耐久,附著力良好,若與磷化底漆配套使用時,可提高漆膜的耐潮、耐鹽霧和防銹功能。
The fireproof paint film is hard and durable with good adhesion. When used together with phosphating primer, it can improve the moisture resistance, salt spray resistance and rust prevention function of the paint film.
防火漆的防火機理大致可歸納為以下五點:
The fire prevention mechanism of fire-proof paint can be roughly summarized into the following five points:
(1) 防火漆自身具有難燃性或不燃性,使被維護基材不直接與空氣接觸,推遲物體著火和削減焚燒的速度;
(1) The fireproof paint itself is flame retardant or nonflammable, so that the maintained substrate does not directly contact with the air, delaying the ignition of objects and reducing the burning speed;
(2) 防火漆除自身具有難燃性或不燃性外,它還具有較低的導熱系數(shù),能夠推遲火焰溫度向被維護基材的傳遞;
(2) In addition to its flame retardancy or non flammability, the fireproof paint also has a low thermal conductivity, which can delay the transmission of flame temperature to the substrate to be maintained;
(3) 防火漆受熱分出不燃惰性氣體,沖淡被維護物體受熱分出的可燃性氣體,使之不易焚燒或焚燒速度減慢;
(3) The fire-proof paint separates non combustible inert gas when heated, and dilutes the combustible gas separated by the maintained object when heated, making it difficult to burn or slow down the burning speed;
(4) 含氮的防火漆受熱分出NO、NH3等基團,與you機游離基化合,中斷連鎖反應,下降溫度。
(4) The nitrogen-containing fireproof paint separates no, NH3 and other groups when heated and combines with organic free radicals to interrupt the chain reaction and reduce the temperature.
(5) 脹大型防火漆受熱脹大發(fā)泡,構成碳質泡沫隔熱層封閉被維護的物體,推遲熱量與基材的傳遞,阻撓物體著火焚燒或因溫度升高而形成的強度下降。防火電纜橋架
(5) The expanded fireproof paint is expanded and foamed by heat to form a carbon foam insulation layer to close the maintained object, delay the transfer of heat to the substrate, and prevent the object from burning or the strength reduction caused by temperature rise. Fireproof cable tray
