本项目涉及一种用于清洗金属零件的水基清洗剂组合物及清洗方法的发明专利。电视显像管(CPT) 或显示管(CDT)是由上百种零件组装而成,其中大部分是金属零件。这些金属零件都是经过冲压而成,表面残留很多油脂和其它污染物,如CPT或CDT用销钉、阳极帽和电子枪零件,是由多工位全自动机械手传递、高速冲床多次拉伸成形,加工过程中油污较多, 而且工件上有盲孔,污染物组分复杂。由于销钉是封接在玻屏中固定荫罩框架的高精度定位结构元件,阳极帽是封接在玻锥上的高压导入元件,元件表面必须
This project involves an invention patent for a water-based cleaning composition and cleaning method for cleaning metal parts. The television tube (CPT) or display tube (CDT) is assembled from hundreds of parts, most of which are metal parts. These metal parts are made by stamping, the surface left a lot of grease and other contaminants, such as CPT or CDT with pins, anode caps and electronic gun parts, is transferred by the multi-station automatic robots, high-speed punch stretching several times, More oil during processing, and blind holes on the workpiece, the composition of pollutants complex. Since the pin is a high-precision positioning structural element that seals the mask frame in the panel, the anode cap is a high-pressure lead-in element which is sealed on the funnel. The surface of the element must be
