防火电缆桥架的构造特性！
哪样桥架具备优良的阻燃性?自然，塑胶吐火桥。喷漆防火桥，通称防火桥，表层原材料为热浸镀锌和冷喷锌，热浸镀锌外型不冷喷锌细致明亮，但热镀锌层的薄厚是冷喷锌层的几十倍。耐腐蚀性也是锌涂层的几十倍。本商品适用10KV下列的电线电缆、变频电缆、照明灯具走线等室内室外架空电缆管沟、隧道施工。阻燃性桥关键分成三种种类：內燃型、外阻燃性型和全阻燃性型。外阻燃性型为外抹一层防火材料，避免外阻燃性毁坏钢桥架的冲击韧性。适用火灾事故多发性场地。内阻燃性型是槽体式或圆盘式电缆线桥，内表层涂有防火材料或嵌入阻燃板。桥架常见于阻燃性挡板，即当电缆线起火时，阻燃性段能够限定打火电缆线的阻燃性长短。全阻燃性型是在內外表层涂敷防火材料或嵌入阻燃板，可维护钢桥的冲击韧性，限定打火电缆线的长短。
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.
防火电缆桥架的构造和特性以下：
The structure and characteristics of fireproof cable tray are as follows:
防火板材是以硅质的原材料和石灰质原材料为关键原材料，选用yx的高压反应釜技术性，掺加一定占比的纺织材料、质轻石料、粘接剂和有机化学防腐剂做成的。防火板材是以硅质的原材料和蛋白质原材料为关键原材料，用一定占比的化学纤维生产加工而成。横截面样子匀称，无弯折、歪曲、裂开、边沿等缺点。
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.
