在潮濕環境下，噴塑電纜橋架的保養要點可以概括為“防潮、防蝕、防損、常檢”四大環節，具體做法如下：

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:

安裝階段先設防線

Set up a defense line first during the installation phase

抬高或排水：若無法避開低洼潮濕區域，應整體抬高橋架安裝高度（≥0.3 m），并在底部設排水孔或排水槽，避免積水長期浸泡。

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.

密封連接：所有蓋板、拼接縫用中性耐候密封膠或EPDM墊片封閉，杜絕水汽從縫隙進入橋架內部。

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.

環境抽濕：在封閉的機房或地下室，可配置小型工業除濕機或懸掛可再生干燥劑，保持相對濕度≤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%.

日常保養三步走

Three Steps to Daily Maintenance

每月外觀檢查：核心查看噴塑層是否出現起泡、龜裂或脫落，發現局部破損立即用同色系環氧修補漆“點補”，防止鋼材裸露生銹。

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.

每季度深度清潔：先用軟布或低壓空氣吹除灰塵，再用中性清潔劑兌水輕擦表面，朂后用清水沖凈并擦干，切忌使用強酸、強堿或鋼絲球，以免破壞涂層。

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.

每半年緊固復查：檢查橋架連接片、螺栓、吊架是否因潮濕而銹蝕松動，及時更換不銹鋼螺栓并補涂防銹油。

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.

長期加強措施

Long term strengthening measures

涂層升級：若環境鹽霧或酸堿濃度高，可在原噴塑層上加涂一層氟碳透明封閉漆，提高耐蝕年限至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.

備用防護：對關鍵區段加裝可拆卸防水罩或PVC護套，雨季來臨前臨時覆蓋，雨季后拆除，既不影響散熱又延長涂層壽命。

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.
