Production process of silver mirror

Abstract

The invention discloses a production process of a silver mirror, relates to the field of production and manufacturing of mirrors, and aims to solve the problems that the silver mirror is short in service life and low in reflectivity. The production process of the silver mirror is characterized by comprising the following steps: cleaning and polishing of glass; sensitization; hypersensitization; silver plating; passivation; preheating; primer spraying ; primer baking; spraying of an epoxy resin coating liquid; spraying of a finish paint; air cooling; surface pickling; surface cleaning; and airing. According to the production process of the silver mirror, the effects that the silver layer is long in durability, high in reflectivity and long in service life can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of glass mirror processing, more specifically, it relates to a production process of a silver mirror. Background technique [0002] Most of the silver mirrors sold on the market are ordinary silver mirrors, whether they are used in furniture, bathroom or decoration. [0003] Ordinary silver mirrors are produced and processed on the basis of ordinary flat glass. The current silver plating method for glass mirrors is as follows: clear glass - sensitization - hypersensitization - silver plating - passivation - secondary passivation - bottoming Paint-primer baking-finish paint-air cooling-pickling surface-surface cleaning-finished product; and at present, the reflectivity of the glass mirror that is required for the silver-plated layer of the glass mirror is high while increasing the thickness of the silver layer, and to The compactness of the silver layer has strict requirements. When the compactness is improv...

[0003] Ordinary silver mirrors are produced and processed on the basis of ordinary flat glass. The current silver plating method for glass mirrors is as follows: clear glass - sensitization - hypersensitization - silver plating - passivation - secondary passivation - bottoming Paint-primer baking-finish paint-air cooling-pickling surface-surface cleaning-finished product; and at present, the reflectivity of the glass mirror that is required for the silver-plated layer of the glass mirror is high while increasing the thickness of the silver layer, and to The compactness of the silver layer has strict requirements. When the compactness is improved, for example, the thickness of the silver layer will be affected. When the thickness is not enough, the silver mirror is prone to oxidation and wear during later use, resulting in thinning of the silver layer and making the silver layer thinner. The reflectivity of the glass mirror is reduced, which affects the service life of the silver mirror
