Abstract
The invention disclosed a method for plating film on a flat glass, especially on a hot flat glass. Said method comprises spraying metal compound powders or metal compound and its solution on the surface of a mobile hot glass with pure oxygen as a carrier gas and spray gun or similar device, and pyrolyzing to obtain a film. The thickness of the film can increase by 50% at most with pure oxygen instead of compressed air, and the maximum deposition efficiency is increased by 50% at most, therefore greatly improving the utilization of the raw material.
Description
[technical field]
The present invention relates to a kind ofly at surface of plate glass, the method for plated film is carried out on Re float glass surface particularly, belongs to the glass coating field.
[background technology]
According to the production process classification, glass coating is divided into on-line coating and off-line coated.
On-line coating is meant that the technological process of plated film is after carrying out being the shaping area of float glass process production line as online thermospray in the float glass manufacturing processed, the beginning of annealing furnace, spray rete by the spray gun of setting up in glass pane surface, rete burns and is attached to glass surface behind the annealed kiln, so name is on-line coating.
Off-line coated is after sheet glass dispatches from the factory, and carries out plated film processing again.Than on-line coating, the firmness of rete must be influenced, so off-line coated " freshness " to original sheet glass is to have certain requirements.Method plated films such as off-line coated general employing magnetron sputtering, vacuum moulding machine.
And on-line coating reacts film forming by high temperature pyrolysis, mainly contains three kinds of technologies.A kind of technology is CVD (chemical vapour deposition) method, and the steam of metallic compound is sent to the glass pane surface of heat by particular device, oxidizing reaction takes place form film; Another kind is a powder injection process, by the device of spray gun or similar spray gun, makes carrier with pressurized air, under it drives, the powder of metallic compound is sprayed directly into the glass pane surface of heat and the pyroreaction film forming; The third is a spray art, by the device of spray gun or similar spray gun, make carrier with pressurized air, under it drives, make metallic compound dissolving or be dispersed in organic solvent or the water and the spray solution of system, spray to the glass pane surface of heat and the pyroreaction film forming with Sprayable.
The conventional online plated film, the coated film deposition rate is not high enough, therefore, needs to seek a kind of method of improved on-line coating, to improve the deposition of plated film.
[summary of the invention]
Technical problem to be solved by this invention is to provide a kind of film coating method that can improve the float glass of coated film deposition rate, and particularly a kind of online process for coating glass, particularly high temperature pyrolysis film coating method can be powder injection processes, also can be liquid ejecting methods.
The present invention solves the problems of the technologies described above by the following technical programs: a kind of method of glass coating, under vector gas drives, Coating Materials is sprayed to the glass pane surface of heat by spray gun, high temperature pyrolysis takes place, be deposited as the metal oxide rete in glass pane surface, wherein make vector gas with oxygen.
Described Coating Materials is with powder or the dissolving of liquid coating raw material or is distributed in the solvent coated solution that obtains.
Perhaps described Coating Materials is Powdered coating raw material.

Metal-salt in the described coating raw material is selected from least a following metal: Fe, Al, Si, Zn, Cr, Mg, Ca, Co, Ni, Ba, Mn, V, Ce, Zr, Mo, Ti, Sn, Cu, Er, Sb, In, Bi, Pr.Only selection is wherein a kind of, also can select any two kinds or its mixture.
Described solvent is from one or both or two or more combinations in the following solvent: benzene, toluene, methyl alcohol, ethanol, propyl alcohol, acetone, methyl chloride, methyl bromide, methyl iodide, ethyl acetate, ethyl formate, ether, water.
Use oxygen and compressed-air actuated mixture as vector gas, also can improve coated film deposition efficient, sedimentation effect is better than compressed-air actuated, but not as purity oxygen.
The film coating apparatus of above-mentioned spray gun or similar spray gun is installed in the tin bath outlet place of floatation glass production line; Also can be installed in the annealing furnace position, and be that annealing temperature is higher than 400 ℃ zone, could guarantee the required temperature of sufficiently high high temperature pyrolysis reaction like this.
The present invention utilizes purified oxygen to replace pressurized air, that is to say, under the drive of purified oxygen, device by spray gun or similar spray gun, with metal compound powders or metallic compound and solution thereof, spray on the glass pane surface that moves of heat high temperature pyrolysis reaction film forming.After oxygen replaced pressurized air, thicknesses of layers can improve 50% at most, that is to say, sedimentation effect has improved 50%.
The non-constant width of range of application of the present invention is applicable to the sunlight controlling coated glass that makes by the high temperature pyrolysis coating process.From the film material analysis, be applicable to metal oxide retes such as cupric oxide, ferric oxide, stannic oxide, chromic oxide, nickel oxide, cobalt oxide, titanium oxide, aluminum oxide, vanadium oxide, magnesium oxide, barium oxide, weisspiessglanz, zinc oxide, cerium oxide, zirconium white, manganese oxide, calcium oxide, molybdenum oxide, Indium sesquioxide, bismuth oxide, Erbium trioxide, Praseodymium trioxide, silicon oxide.
