槽式防火电缆桥架的优点

Advantages of trough type fire proof cable tray

一、传统的金属桥架表面防腐层厚度小，在运输、安装过程中容易破损，而且表面有微细小孔，腐蚀性气体通过小孔容易进入到结构层影响防腐效果；

First, the traditional metal bridge surface corrosion protection layer thickness is small, in transportation, installation process is easy to damage, and the surface has tiny holes, corrosive gas through the small hole easily into the structure layer, affect the anti-corrosion effect;

二、非金属电缆桥架防腐性能较强，但机械强度不够。基于这些情况我公司开发研制了复合环氧树脂复合型玻璃钢电缆桥架：它在复合环氧树脂电缆桥架内增加了金属骨架，不仅保留了原复合环氧树脂电缆桥架的特点，同时又增加了机械强度，可承载大直径的电缆，桥架跨度可达15米。

Two, non metallic cable bridge corrosion resistance is strong, but the mechanical strength is not enough. Based on the situation of our company developed a composite epoxy resin composite glass steel cable bridge: it increases the metal skeleton in the composite epoxy cable bridge, not only retains the original composite epoxy cable bridge characteristics, while increasing the mechanical strength of the cable can be loaded with large diameter, the bridge span is 15 meters.

三、为了解决金属与非金属因膨胀系数不同而引起的脱层问题，在金属和非金属之间加入了结合层；

Three. In order to solve the delamination problem caused by the different expansion coefficient of metal and nonmetal, the bonding layer between metal and nonmetal is added;

四、为了解决了易粉化、易老化的问题，在桥架表面模压了具有抗光照等特殊作用的保护层；

Four. In order to solve the problem of easy powdering and aging, the protective layer with special function such as anti light is molded on the surface of the bridge;

五、复合环氧树脂复合型电缆桥架经权威机构鉴定使用寿命在30年以上，这种产品已经使用了15年，未出现褪色和老化迹象。

Five, composite epoxy resin composite cable bridge, identified by the authority of the service life of more than 30 years, this product has been used for 15 years, there is no sign of fading and aging.

六、玻璃钢电缆桥架包括桥架主体、桥架盖板，两者均为层状结构，各层之间通过模压紧密结合成一体，该桥架主体及桥架盖板结构层由外至内均依次为保护层、防火层、防腐层、保护层。

Six, glass steel cable tray comprises a bridge body, the bridge cover, both of which are layered structure, each layer by molding closely combined into one, the bridge body and the tray cover layer from the outside to the inside in turn as protective layer, fireproof layer, anticorrosion layer, protective layer.
