Abstract
The invention relates to a method of flat on-line coating self-cleaning coated glass. In the method, the lehr outlet of float glass production line is equipped with spraying equipment with a liquid storage pot and a spray gun, the spraying liquid filled in the liquid storage pot contains nano-titanium dioxide with the mass concentration of 0.1% to 3%, and the remainders are alcohols; the distance between the nozzle of the spray gun and the glass face is 200 to 350 mm; the traveling speed of the spray gun is 0.8 to 1.2 m/min; the spraying liquid is sprayed on the float glass surface at the temperature of 60 to 120 DEG C; the film curing lasts 10 to 120 minutes; the self-cleaning coated glass produced by using the method has the advantages of simple, stable and reliable technology, uniform film, low cost, high efficiency, and the like, and is applied to continuous production in large scale.
Description
Technical field
The present invention relates to the method for float glass process online production coating self-cleaning coated glass, specifically utilize the automatic spraying technology of cold junction, spraying one deck nanometer titanium dioxide coating on the glass surface in floatation glass production line annealing furnace exit.
Background technology
Along with the raising day by day of standard of living and aesthetic standards, in the modern urban construction, glass application under construction is more and more, and the whole outer facade of a lot of modern high buildings and large mansions is all decorated with glass.Because the permeability and the strong reflect light effect of glass, the surface that makes glass must keep clean just can represent the attractive in appearance of building.The extensive large-area applications of glass has also been brought the problem that how to keep the glass surface cleaning, common way is cleaning service regularly facade to be cleaned, this cleaning is on the one hand because working aloft, the personnel that clean had very big danger, on the other hand, use a large amount of sanitising agents to clean glass surface, these sanitising agents are all unprocessed directly to enter urban river by urban rainwater pipeline, causes environmental pollution.
In order to solve the difficult problem of above-mentioned building glass cleaning and environmental pollution, produced the automatically cleaning coated glass both at home and abroad, described as CN1312337 and used Prepared by Sol Gel Method TiO
2Automatically cleaning coated glass, CN1267644 have described with magnetron sputtering method and have prepared TiO
2The automatically cleaning coated glass, the production method of above-mentioned patent or need at high temperature to implement, or implement with physical method, complex manufacturing, cost height, production efficiency are low.
Summary of the invention
The purpose of this invention is to provide a kind of method at floatation glass production line cold junction on-line spray self-cleaning coated glass.
The method of flat on-line coating self-cleaning coated glass of the present invention may further comprise the steps:
The spraying equipment that has container for storing liquid and spray gun at floatation glass production line annealing furnace exit device, the spray coating liquor of containing in the container for storing liquid contains the nano titanium oxide of mass concentration 0.1%～3%, all the other are alcohols, the adjusting spray tip is 200～350mm apart from the distance of glass-board surface, the translational speed of spray gun is 0.8～1.2m/min, it is 60～120 ℃ float glass surface that spray coating liquor is sprayed onto temperature, and rete solidified 10～120 minutes.
Above-mentioned alcohols can be in methyl alcohol, ethanol, Virahol, ethylene glycol, propylene glycol and the glycerol one or more.
The thicknesses of layers of the present invention's spraying is generally 30～200nm.
In order to realize the continuous constant pressure feed flow, can adopt two container for storing liquids to automatically switch alternately sprays, utilize the pressure vessel of being with the diaphragm pressure variable valve to provide and stablize adjustable liquid supply pressure to container for storing liquid, organic spray coating liquor that will contain the nano titanium oxide composition is supplied with spray gun, high pressure storage tank pressure 0～5bar is adjustable continuously, and pressure surge is less than 0.1bar, and mist droplet particle size is 100～600 microns behind the compressed air atomizing of spray coating liquor, container for storing liquid automaticallyes switch and uses, and does not have the fluctuation of pressure and flow during switching.
Spray equipment adopts the chain gear to-and-fro movement, and the spray gun that whenever makes a round trip sprays twice on the glass surface certain width, can spray 2 layers, 4 layers, 6 layers on request on glass surface, even more multi-layered.
Beneficial effect of the present invention is:
Liquid-supplying system has two container for storing liquids, can automatically switch arbitrarily each other, does not have the fluctuation of pressure and flow during switching, and pressure-stabilisation is adjustable continuously, and fluctuation is less than 0.1bar; Spray equipment adopts chain gear to-and-fro movement form, have simple in structure, characteristics such as the speed setting scope is big, and is safe and reliable to operation; The whole system device is in floatation glass production line annealing furnace outlet position, and this position sheet glass has certain temperature, need not to repeat heating, save energy, and glass pane surface is fresh, activity is big, and membranous layer binding force is good, and surface clean also need not to clean once more.
Embodiment
Further set forth method of the present invention with example below.
On the floatation glass production line of 450t/d, the wide 3300mm of sheet glass, glass thickness of slab 5mm, sheet glass speed 450m/h, 80 ℃ of annealing furnace outlet position glass-board surface temperature; Spray gun is apart from glass-board surface height 300mm, 80 ° of spray angles, two spray guns, mist width of cloth stack 20%, spray gun is with speed back and forth movement on the width of glass sheet direction of 1.1m/s, and spray coating liquor contains the nano titanium oxide of mass concentration 1.2%, and all the other are methyl alcohol, in glass pane surface spraying twice, thicknesses of layers is about 60nm behind the curing 20min.This product transmitance is low more about 1% than original sheet glass, detects according to building material industry standard " self-cleaning glass photolysis efficiency measuring method ", and photolysis efficiency reaches 4.9%.This product is contained on the glass port, and after 10 days, with the glassy phase ratio that is not coated with from clean film, the dirty degree in surface is the same, after the water flushing, scribbles from the glass of clean film obviously totally than the glass that is not coated with from clean film, has more significantly from clean effect.
