Embodiment

[0023] Embodiment: as shown in Figure 1, a kind of method for making coated decorative glass with vacuum coating machine, its manufacturing process steps are as follows:

[0024] (1) Cleaning of workpiece material, loading alloy wire and workpiece:

[0025] Since the combination of the film and the surface of the workpiece mainly depends on the van der Waald force (dispersion force), the cleanliness of the workpiece surface is crucial to the adhesion of the film layer. Any stains (such as finger marks) with a thickness greater than 0.6 nanometers, etc. Will seriously affect the adhesion of the film layer. Therefore, the surface of the workpiece must be strictly cleaned before coating. If the workpiece is fresh glass, it can be scrubbed only with tap water and a nylon brush, and then rinsed with pure water after blowing off the tap water with a fan. Then follow the cold wind and hot wind to blow off and dry. The above process can be handled by a special washing machine.

Abstract

The present invention discloses method of making coated decorative glass with vacuum coating machine. Under the conditions of 0.1-0.5 Pa vacuum degree and O2 or O2 / Ar circumstance, gas is made to in glow discharge state, titanium wire is evaporated slowly, and titanium vapor is reacted with oxygen ion in the discharge area, so that compact, homogeneous, completely oxidized and high adhesion titania film is formed on the surface of glass workpiece. The coated decorative glass has excellent decorating effect, is durable, and has the functions of eliminating pollutant and purifying air.

Description

technical field [0001] The invention relates to a method for making coated decorative glass with a vacuum coating machine. Background technique [0002] The vacuum coating machine is an older coating equipment that has been around for decades. Initially it was mainly used in the manufacture of aluminum mirrors. It was later used to produce heat-reflecting glass. The principle is that the evaporator made of tungsten, molybdenum and other materials is used in the vacuum chamber at a vacuum degree of 2 to 6×10 -2 Within the range of Pa, metal wire or alloy wire is quickly evaporated (generally ≤ 30 seconds) and deposited on glass and other substrate materials to form a layer of metal film, the color of which is the color of the original metal. [0003] Since the metal film is easily oxidized, aluminum mirrors must be coated with mirror paint. The use environment of heat reflective glass also has strict requirements. The grade and added value of the products are low. The va...
