Example Embodiment
[0041] The present invention will be described in further detail below in conjunction with the drawings and embodiments;
[0042] Such as figure 1 , 2 , A method for coating Teflon-coated wires and insulators as shown in 3, first prepare an alcohol or ketone organic solvent, arrange the wires in a straight line, and string the insulators into rows; insulator coating The method includes the following steps:
[0043] a), degrease
[0044] In order to obtain sufficient surface adhesion on the surface of the insulator, all the grease on the surface of the insulator 3 must be removed first; first use acetone to dissolve the grease on the surface of the insulator 3, and then use a heating device to heat the insulator 3 to 420-450°, so that the surface of the insulator 3 remains The alcohol or ketone organic solvent is completely volatilized;
[0045] b), sandblasting
[0046] The sandblasting machine is powered by compressed air to form a high-speed jet beam, and the quartz sand with a diam...
