摘要
针对海洋大气环境中滨海航天发射场电子电气设备腐蚀防护的应用需求,结合电子电气设备所处的湿热、霉菌、盐雾环境,介绍了电子电路涂层防护技术和电子设备环境控制保护技术及其应用。传统的三防漆(胶)涂覆防护技术是常规电子电路防护技术,纳米涂层防护体系适用于高端关键电子设备的防护;内循环盐雾控制技术通常应用于防护要求高、设备数量多且较为密封的工作间,气相缓蚀剂适用于密闭小空间内电子电气防腐蚀。最后,针对滨海发射场电子电气设备腐蚀防护的实际应用,提出进行典型电子电气设备的可靠性与寿命评价的建议。
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 three-proof paint(glue)coating protection technology is the conventional electronic circuit protection technology.Nano-coating 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.
