产品在生产过程中常需对某部分表面进行噴漆,而邻近的表面則不允許噴上漆。生产中为了做到这一点,施工前必須采用夹具、涂油或其他方法,但是这些方法都有缺点。最近我們試驗成功一种比較簡便的方法。在施工前对这些不需噴漆的表面涂上一层大約厚0.25～0.4毫米有机玻璃的氯仿溶液,氯仿在极短时間內就会揮 Products in the production process often need to paint a part of the surface, while the adjacent surface is not allowed to spray paint. To do this in production, fixtures, oiled or other methods must be used prior to construction, but these methods have drawbacks. Recently we tested a relatively easy way to succeed. Before the construction of these unpainted surface coated with a layer of about 0.25 ~ 0.4 mm thick plexiglass solution of chloroform, chloroform in a very short period of time will play
