电缆桥架的防火能力植根于其材料和制造过程。 不同材料和不同制造工艺的防水能力有所不同。 因此，防火电缆桥架的标准化设置就显得尤为重要，这可以使防火电缆桥架更加统一可靠。
The fireproof ability of cable tray is rooted in its material and manufacturing process. Different materials and different manufacturing processes have different waterproof ability. Therefore, the standardized setting of fire-proof cable tray is particularly important, which can make the fire-proof cable tray more unified and reliable.
防火电缆桥架分为内阻燃型，外阻燃型和全阻燃型。 更重要的部分是防火板。 防火板以硅数据和钙数据为主要原料，纤维数据为一定比例。 的高压灭菌技术生产的轻质骨料，粘合剂和化学添加剂的组合。 经过加工成型，断面形状均匀，没有弯曲，扭曲，开裂，边缘等缺点，但无论哪种防火桥，都必须符合电缆桥架的国家标准。
Fireproof cable tray is divided into internal flame retardant type, external flame retardant type and full flame retardant type. The more important part is the fire board. The main raw materials of fireproof board are silicon data and calcium data, and the fiber data is a certain proportion. The leading autoclave technology produces a combination of lightweight aggregates, adhesives and chemical additives. After processing, the cross-section shape is uniform, without bending, twisting, cracking, edge and other shortcomings, but no matter what kind of fire bridge, it must meet the national standard of cable tray.
防火涂料是一种的钢结构维护产品。 它由聚合物合成树脂作为成膜物质制成，并通过使用阻燃剂，发泡剂，碳化剂和高温耐火材料制成。 在高温条件下，涂层具有发泡膨胀作用，构成了柔软的海绵状碳化绝热层，因此，受支撑的钢结构不会因高温火焰的作用而急剧软化和变形，强度 不会急剧下降。 表面防火涂层喷涂均匀，平整，无明显色差。
Fire retardant coating is an efficient product for steel structure maintenance. It is made of polymer synthetic resin as film-forming material, and is made by using flame retardant, foaming agent, carbonizing agent and high-temperature refractory. At high temperature, the coating has foaming expansion effect, forming a soft sponge like carbonized insulation layer. Therefore, the supported steel structure will not soften and deform rapidly due to the effect of high temperature flame, and the strength will not drop sharply. The surface fireproof coating is sprayed evenly and flat without obvious color difference.
Nowadays, fireproof cable tray has been used in various cable laying fields and plays an outstanding role in cable maintenance. They have excellent cable flame retardant and fire protection, which is unmatched by other stainless steel bridge.
1.防火电缆桥架重要地基于防火电缆的国家标准。 防火层的厚度要求大于或等于1mm，耐火性必须为30分钟。 这是防火电缆防火涂料的标准。 防火材料是钢，防火电缆的外层也覆盖有防火材料。
1. Fireproof cable tray is based on the national standard of fireproof cable. The thickness of the fireproof layer should be greater than or equal to 1 mm, and the fire resistance must be 30 minutes. This is the standard of fireproof coating for fireproof cable. The fireproof material is steel, and the outer layer of the fireproof cable is also covered with fireproof material.
2.尝试选择钢制或不燃和阻燃材料的电缆桥架。 防火电缆桥架采用钢外壳，双层防火罩，并装有无机防火箱。 隔热层厚度均匀为25mm，双层罩用于通风散热，内部喷涂防火涂料。 防火电缆桥架在着火时会肿胀。 在60分钟的防火测试中，电缆没有损坏。 支撑结构良好。
2. Try to choose the cable tray made of steel or non combustible and flame retardant materials. The fireproof cable tray adopts steel shell, double-layer fireproof cover and inorganic fireproof box. The thickness of the heat insulation layer is 25 mm, the double-layer hood is used for ventilation and heat dissipation, and the interior is sprayed with fireproof coating. Fire resistant cable tray will swell in case of fire. In the 60 minute fire test, the cable was not damaged. The supporting structure is good.
The higher standard of fire-proof cable is bs6387 standard in UK. If laying fire bridge for common cable, the following points should be paid attention to:
外层涂有防火涂料。 防火桥在着火后不会燃烧，从而阻止了火势蔓延。 它具有优异的防火和阻燃效果，并具有防火，耐油，耐腐蚀，无毒，无污染的特点。
The outer layer is coated with fireproof coating. The fire bridge will not burn after the fire, thus preventing the spread of the fire. It has excellent fireproofing and flame retardant effect, and has the characteristics of fireproofing, oil resistance, corrosion resistance, non-toxic and pollution-free.
实际上，桥梁本身并没有着火。 只能着火了。 因此，许多项目现在都使用防火电缆来节省电缆桥架和维护成本。
In fact, the bridge itself was not on fire. It's only on fire. As a result, many projects now use fire-resistant cables to save cable tray and maintenance costs.
防火桥在普通桥的表面喷涂一层防火涂料，起到防火，阻燃的作用。 防火涂料的防火和阻燃原理，防火桥的保护厚度根据JB / T 10216-2000《电子控制配电》的“电缆桥架”表10的要求，镀层大于12μm，热 镀层大于65μm，喷涂大于50μm，防火大于500μm，可以用测厚仪进行测量。
A layer of fire retardant coating is sprayed on the surface of the ordinary bridge to prevent fire and flame. According to the requirements of table 10 of "cable tray" in JB / T 10216-2000 "electronic control power distribution", the thickness of coating is greater than 12 μ m, hot coating is greater than 65 μ m, spraying is greater than 50 μ m, and fireproof is greater than 500 μ m, which can be measured by thickness gauge.
