Problems solved by technology

[0014] In addition, in this field, the entire glass product is vertically immersed in a tank full of liquid medicine to solve the problem of thin coating at the edges and corners, but the surface of the product is coated without coating, resulting in waste of production costs and low production efficiency; or The surface that does not need to be coated will be protected with a film in advance, and then immersion treatment. The problem with this treatment is that the production cost of a single film is very high, and the production efficiency is also very low. It is impossible to form a large-scale production line.
Secondly, some manufacturers use physical methods, such as vacuum deposition of silver, they must use large-scale vacuum equipment to achieve quantitative production, resulting in increased production costs

Embodiment 1

[0051] Embodiment 1: as Figure 5 As shown, silver mirror production is performed on a diamond-like eight-sided tapered glass body with a height of 1.95mm

[0052] The first group: using the flat glass silver mirror production process, the silver nitrate solution used is 250 g / L

[0053] The second group: Spray with 8 g / L silver nitrate (no frame)

[0054] The third group: use 8 grams per liter of silver nitrate to spray (adopt surrounding frame of the present invention)

[0055] First of all, the eight-sided tapered glass body is covered with 220*220mm PVC plastic, and the PVC plastic film is used as a partial protection of the non-processed surface and positioning; it is put into the tray 18, and the material is loaded;

[0056] Then, carry out cleaning, use mechanical method to add selenium oxide powder to scrub or adopt ultrasonic wave to add surfactant to clean, clean and rinse with deionized water;

Abstract

The present invention discloses a technique and device for producing glasses from non-plane glass. The technique comprises steps of locally protecting a non-processed face of non-plane glass to be processed; rinsing; sensitizing treatment; silver plating; after positioning the non-plane glass to be processed, pressing downwards a window frame, encircling the non-plane glass to be processed in the window frame, spraying silver nitrate mixed liquid medicament onto the window frame through a spraying device until the liquid completely submerge the highest point of the non-plane glass to be processed to promote the liquid medicament to completely react with surface of the glass chemically; after reacting for a while, lifting the window frame to discharge the reacted liquid medicament; rinsing out the liquid medicament, winding to remove water, drying with hot wind; spraying protective paint, baking; cooling the glass face, taking out the glass. The technique is applied to making reflection layer of non-plane shuttle mirror. Because of the window frame used in production device, production cost is greatly saved; production efficiency is greatly improved; and massive flow line production can be realized.

Description

Technical field: [0001] The invention relates to a silver mirror production process, in particular to a silver mirror production process of non-planar glass or glass with irregular shapes and equipment thereof. Background technique: [0002] The silver mirror production process of flat glass in the prior art is generally as follows: first, the flat glass is sent to the upper end of the production line, polished, cleaned, sensitized, silver-plated, copper-plated, painted, dried, painted again, and baked again. , cleaning, off-line and other processes to complete the production of flat glass silver-plated mirrors, and the silver mirror plates coming out of the export end can be packaged and sold at the factory. [0003] The whole process can be described in detail as follows [0004] 1. The flat glass to be processed is sent to the production line; [0005] 2. Cleaning, after removing organic stains, polishing, and cleaning with pure water again, the glass is cleaned; [00...
