Wrapping and insulating method of electroplating hanger
The so-called wrapping is to use 15-20mm wide polyvinyl chloride film tape to wrap the parts of the hanger that need to be insulated from the bottom to the top, and the plastic must be tightly pulled when wrapping. Tape, when wrapping the second layer, 1/2 of the plastic tape should be pressed on the first layer. At the end of the winding, the plastic tape can be melted and pressed by hot melt, or it can be tied tightly with metal wire or plastic film. The bandaging method is easy to operate and the source of materials is easy to obtain, but it is not easy to fasten the small poles. It is suitable for simple single-hook hangers, especially cylindrical parts. Sometimes it is difficult to fully meet the requirements of square cylinders. , Its defects are shown in the figure below. The disadvantage of the bandaging method is that some curved, non-straight parts are more difficult to tie tightly, and there will inevitably be gaps. The solution will be retained during work, which may contaminate the next process solution. Therefore, the bandage should be as tight as possible. Strengthen the cleaning between processes. |
