云南地区防火桥架和镀锌桥架用途差别

   云南地区电缆电线安装使用主要是防火桥架和镀锌桥架，在不同的场地要求不同，下面介绍他们的用途

   云南防火桥架适用于 10KV 以下的电力电缆，并可用于控制室内架空电缆、照明配线等的敷设；防火板桥架主要由粘合剂复合的耐火隔板、与金属结合的耐火底板及其它耐火基材组成，在其上加装耐火涂料。云南昆明防火桥架在遇火后不能燃烧，阻隔了火灾的蔓延。防火桥具有极好的防火阻燃效果，耐火、耐油、耐腐蚀、无毒、无污染、整体安装方便等特点。防火涂料有涂层薄、耐火极限高、粘接力强的特点。 

    云南镀锌桥架，一般情况下应用在潮湿、腐蚀性强环境下。根据工地需求分为热镀锌和电镀锌。

    热镀锌云南桥架工艺：把钢或铸件浸入熔化的锌溶液中，在其表面上形成锌-铁合金或锌-锌合金及锌-铁合金涂层的工艺和方法。

    冷镀锌云南电缆桥架工艺：对钢进行化学清洗后，将其放入含氧化锌的镀液中。DC 一极接钢，一极接镀锌板。通电后，锌在分子状态下被钢材表面置换。若加亮剂钝化，则表现为彩云状亮镀层。钢结构应用的镀锌一般防锈效果不太好，主要镀锌量达不到，镀锌不均匀，一般 2、3 年生锈，质量差的暴露在潮湿环境下十几天生锈，热镀锌层厚，耐腐蚀性强。冷镀锌层比热镀锌层亮，但薄，耐腐蚀性弱。

Yunnan area cable and wire installation and use is mainly fireproof bridge and galvanized bridge, different requirements in different sites, their use is introduced below

Yunnan fire bridge is suitable for power cables below 10KV, and can be used for laying overhead cables and lighting wiring in the control room; Fireproof board bridge is mainly composed of adhesive composite refractory partition board, refractory base plate combined with metal and other refractory substrate, on which fire retardant coating is installed. Yunnan Kunming fire bridge in the fire can not burn, cut off the spread of the fire. Fireproof bridge has excellent fire retardant effect, fire resistance, oil resistance, corrosion resistance, non-toxic, pollution-free, convenient installation and so on. Fire retardant coating has the characteristics of thin coating, high fire resistance limit and strong adhesion.

Yunnan galvanized bridge is generally used in wet and corrosive environment. It can be divided into hot dip galvanizing and electric galvanizing according to site demand.

Hot-dip galvanizing Yunnan bridge process: the process and method for dipping steel or casting into molten zinc solution and forming zinc-iron alloy or zinc-zinc alloy and zinc-iron alloy coating on its surface.

Cold galvanized Yunnan cable bridge process: after chemical cleaning of steel, put it into the plating solution containing zinc oxide. DC one pole is connected with steel, one pole is connected with galvanized sheet. After electricity is applied, the zinc is replaced by the steel surface in its molecular state. If the brightening agent is passivated, it shows a bright cloud coating. Steel structure application of galvanized anticorrosion effect is not very good, the main amount of galvanized is not up to, galvanized uneven, generally 2, 3 years of rust, poor quality exposure to rust in a humid environment for more than ten days, hot dip galvanized layer thick, strong corrosion resistance. Cold galvanized layer is brighter than hot galvanized layer, but thin, weak corrosion resistance.
