在光学仪器的调修过程中,清洗大型投影仪的大反射镜往往是一个难题。擦洗方法不当时不仅会产生划痕,而且往往会出现彩色花斑,或者二者兼有。近来我们用几种不同的擦洗方法擦洗了几台大型投影仪大反射镜面上存在的霉、灰尘和油污,基本上摸索出一种较为理想的工序。此工序归纳为:一吹、二扫、三滚擦(先用温水,后用汽油、酒精和乙醚)。吹,就是用洗耳球等吹去浮在镜面上和固定镜架上的灰尘,以防擦洗时使灰尘沾在棉球上使镜面产生划痕; 扫,就是对吹不掉的灰尘或别的脏物,可
In the optical equipment repair process, cleaning large projector mirror is often a big problem. Scratches not only scratch the wrong way, but often there will be color spots, or both. Recently we used several different scrubbing methods to scrub several molds, dusts and greases on the large mirror surface of large projectors, and basically found out a more ideal process. This process is summarized as: a blow, two sweep, three roll rub (first with warm water, after gasoline, alcohol and ether). Blow, is to use the ear wash and other blown floating on the mirror and the fixed frame of the dust to prevent the scrub when the dirt stained cotton balls so that the mirror scratches; sweep, that is, can not blow on the dust or do not The dirt can be
