Embodiment 1

[0036] In the tin tank of the float glass production line, where the temperature of the glass ribbon is 780°C, a copper metal electrode is set as the anode, and the tin liquid is used as the cathode to keep the hydrogen concentration in the tin tank at 5%, and the nitrogen concentration at 95%. The distance between the control electrode and the glass ribbon is 6 mm, the pulling speed of the glass ribbon is 400 m / h, the direct current passing through the electrode is 28.6 amps, and the low-melting point metal lead is sent between the anode and the glass ribbon through the feeding device, so that The metal is electrolyzed into ions and penetrates to the surface of the glass ribbon for 8 microns, and is reduced by hydrogen in the tin bath to form a copper-lead metal film on the surface of the moving hot glass ribbon. A reactor is set above the glass ribbon in the tin bath where the temperature is 650°C, and the coating mixed gas with silane as the main component is sent between th...

Embodiment 2

[0038] In Example 1, the low-melting-point metal lead is replaced by the low-melting-point metal bismuth, and other parameters and processes are kept unchanged, so that brown-red multilayer coated glass can be obtained.

Embodiment 3

[0040] In Example 1, metal electrodes of cobalt, nickel, silver, chromium, and iron are used as anodes instead of metal copper electrodes, and other parameters and processes are kept unchanged to obtain light blue, light green, and golden multilayers respectively. Coated Glass.

Abstract

The glass with coated multilayer color film consists of glass, metal film layer penetrating to 2-15 micron below glass surface and silicon film deposited on the surface of glass. The production process includes ion penetration to form metal film and chemical vapor deposition to form silicon film. In the tin tank in float glass producing line, electric field is applied to high temperature glass belt, so that metal ions migrate into glass belt surface layer before being reduced in reduction atmosphere into metal colloid to form the metal film layer. Then in a reactor, one layer of silicon film is formed on the moving glass belt through chemical vapor deposition. Through altering the kind of penetrated metal, glass in the required color may be produced. The outer silicon film can strengthen the stability and reflecting effect of the metal film, reduce the transmittance of the metal film and raise the surface wear resistance.

Description

technical field [0001] The invention relates to a coated glass and a production method thereof, in particular to a glass coated with a colored multilayer film and a method for online coating of a colored multilayered film glass by a float method. Background technique [0002] The existing float glass with online color coating, one is to coat the surface of the glass with a metal film. Chinese patent CN1035651 discloses a method of using metal ions to penetrate into the upper surface of the glass ribbon under the action of an electric field to color the glass. This kind of colored glass has relatively low reflection of visible light and solar radiation, and the chemical stability of the colored layer is poor. The other is to coat the silicon film on the surface of the glass. Usually, the chemical vapor deposition method is used to coat the silicon film. This kind of coated glass, when the substrate has no color, the reflection of the glass film surfa...
