Long span cable trays mainly carry wires and cables, so it is necessary to do a series of anti-corrosion work. The following cable tray manufacturers will introduce how to carry out anti-corrosion for cable trays.

1、可以使用氯磺化底漆二道、面漆二道做为防腐桥架涂层结构。、

1. Two coats of chlorosulfonated primer and two coats of finish paint can be used as the coating structure of anti-corrosion bridge

2、金属表面除锈质量的好坏，直接影响到大跨距电缆桥架的使用寿命，在现场除锈方法使用的是砂轮机除锈或者是进行人工除锈，除锈的级别需要达到ST3级别，在表面除锈之后，需要在4小时之内涂上底漆。如果发现出现新锈的时候，这就需要重新进行处理。

2. The quality of metal surface derusting directly affects the service life of long-span cable tray. The on-site derusting method is to use grinder derusting or manual derusting. The derusting level needs to reach ST3 level. After surface derusting, primer needs to be applied within 4 hours. If new rust is found, it needs to be treated again.

3、涂层的施工使用的是滚涂和刷涂，还需要符合，层间应纵横交错，单层往复进行涂平均为止不能够漏涂。

3. The coating construction uses roller coating and brush coating, which also needs to meet the requirements. The layers shall be crisscross, and the single layer shall be painted back and forth, and there shall be no missed coating until the average.

在防腐施工时各种工序之间需要进行质量的检查，在前道工序合格之后才可以进行下一道的工序施工，一道工序在完毕之后需要进行彻底的检查，如果发现有缺陷，需要及时的修补，涂层的厚度以及涂装的道数设计需要符合要求，要求表面平滑无痕，没有针孔、流坠、粉化、破损等情况。

During anti-corrosion construction, quality inspection shall be carried out between various processes. The next process can be carried out only after the previous process is qualified. After the completion of the first process, it shall be thoroughly inspected. If defects are found, they shall be repaired in time. The thickness of the coating and the number of coating passes shall meet the requirements. The surface shall be smooth without marks, pinholes Sagging, pulverization, damage, etc.
