为保证金属表面光亮、不生锈，我们建议：
To ensure a bright and rust free metal surface, we recommend:
①定期检查不锈钢电动伸缩门的表面情况，经常清洁擦洗，*附着物，排除引起腐蚀的外在因素。
① Regularly inspect the surface condition of stainless steel electric telescopic doors, regularly clean and scrub, remove attachments, and eliminate external factors that cause corrosion.
②对于无工业污染的地区，在安装不锈钢电动伸缩门时应告知相关人员，选用合适的不锈钢材质，如304等。
② For areas without industrial pollution, when installing stainless steel electric telescopic doors, relevant personnel should be informed and appropriate stainless steel materials such as 304 should be selected.
③沿海地区应采用316不锈钢，能抵抗海水腐蚀。
③ Coastal areas should use 316 stainless steel to resist seawater corrosion.
不锈钢电动伸缩门一旦生锈，如何处理？
How to handle stainless steel electric telescopic doors once they rust?
a) 化学法：
a) Chemical method:
用酸洗膏或喷剂辅助钝化锈件形成氧化铬膜，恢复其耐腐蚀性能。酸洗后，用干净的水正确冲洗非常重要，以去除所有污染物和酸残留物。全部处理完毕后，用抛光设备重新抛光，并用抛光蜡封口。对于有轻微锈斑的零件，也可以用汽油和机油的1:1混合液，用干净的抹布擦拭锈斑。
Use pickling paste or spray to assist in passivating rust parts to form a chromium oxide film and restore their corrosion resistance. After pickling, it is important to rinse properly with clean water to remove all pollutants and acid residues. After all processing is completed, use polishing equipment to re polish and seal with polishing wax. For parts with slight rust spots, a 1:1 mixture of gasoline and engine oil can also be used to wipe the rust spots with a clean cloth.
b) 机械法：
b) Mechanical method:
喷砂清理、玻璃或陶瓷颗粒喷丸、湮没、刷涂和抛光。可以通过机械方法擦去先前去除的材料、抛光材料或湮灭材料造成的污染。各种污染，尤其是外来的铁颗粒，都可能成为腐蚀源，尤其是在潮湿的环境中。
Blast cleaning, glass or ceramic particle peening, annihilation, brushing, and polishing. Contamination caused by previously removed materials, polished materials, or annihilated materials can be removed by mechanical means. Various types of pollution, especially foreign iron particles, can become sources of corrosion, especially in humid environments.
