摘要: 为解决某装备光学镜筒局部导电、局部硫酸阳极氧化着黑色的工艺技术难题,筛选出一套适合该装备光学镜筒局部表面处理的工艺方法,采用某涂覆液经3~5次涂覆成型,遮蔽层厚度为120 μm,固化温度为93℃,固化时间为35 min.通过遮蔽层对导电表面与硫酸阳极氧化溶液的有效隔离,实现了对光学镜筒导电表面进行保护的目的,满足了该装备光学镜筒局部导电、局部硫酸阳极氧化着黑色的特殊使用要求.Abstract: In order to solve technical problems about partial conduction on the surface of equipment optical lens,a series of process method which adapted to the partial surface of equipment optical lens was screened out,the paint category of shielding film coating process was determined,the thickness of shielding film was 120 μm,the curing temperature was 93℃,the curing time was 35 min. The shielding film could protect optical lens based on effective isolation between conductive surface and sulfuric acid anodic oxidation solution through shielding film.It could realize the purpose of protecting the conductive surface of optical lens,and satisfy the request of the particular use of partial conduction and partial blackening after sulfuric acid anodic oxidation on the surface of equipment optical lens.
