Problems solved by technology

[0003] Pickled lenses will have black edges around them during use. The main reason is that the coating (silver layer or aluminum layer) on the lens is oxidized and blackened under the action of electrolytes (acid, alkali, salt), similar to silver. If the device is left for a long time, it will turn black; if the lens is used for a long time, the coating will oxidize and turn black, which will affect the normal use of the lens

Embodiment

[0015] A method for enhancing the anti-corrosion time of pickling lenses, comprising the following steps:

[0016] S1, first wash the semi-finished lens after the pickling process with clean water, dry or air-dry for later use;

[0017] S2, affix a protective film for preventing the mirror surface from being scratched on the side of the mirror surface of the semi-finished lens product treated in S1, and paste a layer of process film on the back side of the semi-finished lens product;

[0018] S3, use a vertical engraving machine to engrave the semi-finished lens that has been processed by S2, and engrave a 2mm wide sand line on the edge of the pickled lens;

[0019] S4, sanding the sand line engraved on the edge of the lens in S3, after the sanding is completed, remove the protective film on the mirror surface and the process film on the back, clean the semi-finished lens, and then dry or air dry it;

[0020] S5, pasting a layer of protective film on the mirror surface of the...

Abstract

The invention discloses a method for enhancing the anticorrosion time of an acid washing lens. The method comprises: washing a semi-finished product lens being subjected to acid washing by using clearwater, drying or carrying out air drying so as to be spare, adhering a protection film for protecting a mirror surface from being scratched to the mirror surface side of the semi-finished product lens, adhering a layer of a process film to the back surface side of the semi-finished product lens, engraving the semi-finished product lens by using a vertical engraving machine to obtain a sand line with a width of 2 mm at the edge of the lens being subjected to acid washing, frosting the sand line, removing the protection film from the mirror surface and the process film from the back surface after the frosting, washing the obtained semi-finished product lens, and adhering a layer of a protection film to the mirror surface of the lens so as to obtain the anticorrosion enhanced lens. Accordingto the present invention, the edge of the lens is subjected to the sand line treatment, such that the oxidation reaction rate of the plating layer on the lens under the action of the electrolyte is effectively reduced so as to retard the corrosion on the edge of the lens and substantially improve the service life of the lens.

Description

technical field [0001] The invention belongs to the technical field of lens pickling, and in particular relates to a method for enhancing the anti-corrosion time of pickling lenses. Background technique [0002] Lens, also known as mirror heart, is a framed painting heart, which is suitable for being placed in the frame, so it is called mirror heart. Its form can be horizontal or vertical, and it is a simple and convenient installation. The light transmittance and mechanical and chemical properties of glass lenses are relatively good, with a constant refractive index and stable physical and chemical properties. There are many types of lenses, which are widely used in people's daily life. [0003] Pickled lenses will have black edges around them during use. The main reason is that the coating (silver layer or aluminum layer) on the lens is oxidized and blackened under the action of electrolytes (acid, alkali, salt), similar to silver. If the device is left for a long time,...
