Application Progress of Corrosion Protection for Electronic and Electrical Equipment in Coastal Space Launch Sites

According to the actual requirements of corrosion protection for electronic and electrical equipment in coastal space launch sites in the environment of marine atmosphere, coating protection technology for electronic circuit and environmental control protection technology for electronic equipment are introduced as well as their applications, in combination with the humid and hot environment containing mold and salt fog. Traditional threeproof paint (glue) coating protection technology is the conventional electronic circuit protection technology. Nanocoating protection system is suitable for the protection of high-end key electronic equipment. Internal circulation salt spray control technology is usually applied to the workplaces with high protection requirements, large number of equipment, and relatively sealed conditions. And vapor phase corrosion inhibitor technology is suitable for the corrosion protection for electronic and electrical appliances in a confined small space. Finally, according to the application of electrical and electronic equipment in coastal space launch sites, some suggestions are put forward to evaluate the reliability and life of typical electronic and electrical equipment in coastal space launch sites.
