在潮湿环境下，喷塑电缆桥架的保养要点可以概括为“防潮、防蚀、防损、常检”四大环节，具体做法如下：

In humid environments, the maintenance points of spray painted cable trays can be summarized as four major steps: "moisture prevention, corrosion prevention, damage prevention, and regular inspection". The specific methods are as follows:

安装阶段先设防线

Set up a defense line first during the installation phase

抬高或排水：若无法避开低洼潮湿区域，应整体抬高桥架安装高度（≥0.3 m），并在底部设排水孔或排水槽，避免积水长期浸泡。

Lifting or Drainage: If it is impossible to avoid low-lying and humid areas, the installation height of the bridge should be raised as a whole (≥ 0.3 m), and drainage holes or channels should be set at the bottom to avoid long-term immersion in water.

密封连接：所有盖板、拼接缝用中性耐候密封胶或EPDM垫片封闭，杜绝水汽从缝隙进入桥架内部。

Sealed connection: All cover plates and splicing joints are sealed with neutral weather resistant sealant or EPDM gaskets to prevent water vapor from entering the interior of the bridge through the gaps.

环境抽湿：在封闭的机房或地下室，可配置小型工业机或悬挂可再生干燥剂，保持相对湿度≤60 %。

Environmental dehumidification: In enclosed computer rooms or basements, small industrial dehumidifiers or hanging renewable desiccants can be installed to maintain a relative humidity of ≤ 60%.

日常保养三步走

Three Steps to Daily Maintenance

每月外观检查：查看喷塑层是否出现起泡、龟裂或脱落，发现局部破损立即用同色系环氧修补漆“点补”，防止钢材裸露生锈。

Monthly appearance inspection: Focus on checking whether the spray coating has bubbles, cracks, or peeling. If any local damage is found, immediately use the same color epoxy repair paint to "spot repair" to prevent the steel from being exposed and rusting.

每季度深度清洁：先用软布或低压空气吹除灰尘，再用中性清洁剂兑水轻擦表面，朂后用清水冲净并擦干，切忌使用强酸、强碱或钢丝球，以免破坏涂层。

Quarterly deep cleaning: First, use a soft cloth or low-pressure air to blow away dust, then gently wipe the surface with a neutral cleaning agent mixed with water. After that, rinse with clean water and wipe dry. Avoid using strong acids, alkalis, or steel wire balls to avoid damaging the coating.

每半年紧固复查：检查桥架连接片、螺栓、吊架是否因潮湿而锈蚀松动，及时更换不锈钢螺栓并补涂防锈油。

Half yearly fastening review: Check whether the bridge connecting pieces, bolts, and hangers are corroded or loose due to moisture, replace stainless steel bolts in a timely manner, and apply anti rust oil.

长期加强措施

Long term strengthening measures

涂层升级：若环境盐雾或酸碱浓度高，可在原喷塑层上加涂一层氟碳透明封闭漆，提高耐蚀年限15年以上。

Coating upgrade: If the environmental salt spray or acid-base concentration is high, a layer of fluorocarbon transparent sealing paint can be added to the original spray coating to increase the corrosion resistance period to more than 15 years.

备用防护：对关键区段加装可拆卸防水罩或PVC护套，雨季来临前临时覆盖，雨季后拆除，既不影响散热又延长涂层寿命。

Backup protection: Install detachable waterproof covers or PVC sheaths on key sections, temporarily cover before the rainy season, and remove after the rainy season, which does not affect heat dissipation and extends the coating life.
