Embodiment Construction

[0015] Such as figure 1 As shown, the rectification filter circuit in this embodiment is composed of a transformer T1, a rectification diode D1, and a filter capacitor C1, and the time control circuit is a time relay composed of a relay J and a timer M, wherein the two contacts of the relay J are respectively connected to The two AC input ends of the rectification filter circuit. The output voltage of the rectifying and filtering circuit in this embodiment is 50V, and the current is about 3A, which can be used for stripping paint of small metal parts such as watch case surfaces. The rectifier and filter circuit can output different output voltages according to the different paint-removing metal parts. If the object is large, the required voltage and current should be correspondingly high, so that there will be more air bubbles, and the required paint-removing time will be correspondingly longer. some. The heating element R is directly connected to 220V AC voltage, and a temp...

Abstract

The running water depainting method includes the following steps: placing two spaced metal conductive bodies in conductive medium, then respectively connecting the positive and negative electrodes ofoutput voltage after rectified and filtered onto said two metal conductive bodies, and the metal component required for depainting can be hung from conductive body connected with negative voltage andnegative electrode, then power supply is switched on, the voltage can be inputted onto both two metal conductive bodies, so that the paint film on the surface of metal component can be removed. Said depainting machine includes rectifier filter circuit, container for holding conductive medium, two emtal conductive bodies and heating body. Its depainting speed is high and its cost is low.

Description

technical field [0001] The invention relates to a method for removing various paint films such as electrophoretic paint film, spray paint, baking paint film and plastic spray film coated on the surface of metal materials with tap water, and also relates to a water paint stripper for the method. Background technique [0002] Existing removal of all kinds of paint films coated on the surface of metal materials is mainly done by chemical organic substances such as thinner and special paint remover. For example, to clean the surface of a watch case, it must first be soaked in thinner. Then manually scrub several sides. This is not only harmful and toxic to the cleaning workers, but also takes a lot of effort; in addition, the cost of cleaning is high and not environmentally friendly. Contents of the invention [0003] The object of the present invention is to provide a method for stripping paint with tap water, which has high paint stripping speed, low cost, environmental pro...
