Abstract
The invention provides a method for rapidly inspecting large-area Low-E coated glass coating defects. The method is characterized in that corrosive steam is adopted for eroding a coating in a closed environment, defective parts and other parts show different appearance morphologies due to the fact that the eroding velocities of the defective parts and other parts in the coating are different, and therefore the positions and types of the defects are judged rapidly and visually. The method is particularly suitable for defect inspection of remote temperable products, the tempering treatment process can be omitted, and the defect inspecting time is greatly saved.
Description
[technical field]
The present invention relates to special glass field, especially can the low radiation coated glass of tempering.
[background technology]
Low emissivity (also known as Low-E) glass is a kind of extraordinary coated glass of energy-saving effect, has begun to now be widely used in building, automobile, and the industrial circle such as electric refrigerator, microwave oven.It is the film layer that plating last layer is special on the glass substrate, it is allowed to the energy of short wavelength, such as visible ray and uv energy, by this film layer, and reflects the energy of long wavelength, and such as infrared energy, final realization reduces heating or the effect of energy consumption for cooling.
Along with the extensive application of Low-E glass, the requirement of Low-E glass is improved constantly by market.
Low-E glass be faced with from non-tempering process to can tempering process upgrading；This upgrading is the inexorable trend improving off-line Low-E glass production efficiency, and can meet the market requirement to techniques such as curved steel, doublings.But comprehend at tempering and film plating layer is had a huge impact, the change of such as material structure, the oxidation of metal, film layer change in volume etc..The trickleest open defect can not be visually noticeable before tempering processes, but it is visible to be amplified to naked eyes after tempering process, thus product quality problem occurs.Need timing sampling that monolithic glass carries out tempering process the most in process of production, check defect situation.
This step sampling check operation has two kinds of methods:
A kind of method is that big for monoblock plate carries out tempering process, then hangs sample inspection.The method is high to the requirement of equipment, needs the large-scale annealing furnace having deep processing and production line near off-line coated line；Glass will be through the process cut, grind, wash before tempering, and the time of needs is long；The tempering of glass will necessarily interrupt the production schedule of deep processing and production line, even needs to adjust steel process and could meet tempering requirement.So general Low-E glass manufacturers is not adopted in this way.
Another kind of method is that big plate cuts into some small size models, carries out tempering process respectively, then hangs sample inspection.The method is flexible, and the highest to equipment requirements, it is only necessary to add a little annealing furnace of test-type, most Low-E glass manufacturers is adopted in this way.But the method has wanted monoblock, and big version tempering needs whole for small-shape tempering, and small test stove once can only a piece of small-shape of tempering, so requiring time for the longest, it is impossible to pinpoint the problems in time.
So, existing film layer defects inspection method limits the efficiency of quality examination very much, there is also bigger hidden danger of quality.We need a kind of new method, it is possible to quickly comprehensively obtain the defect situation of film layer, and the high-efficiency and continuous for production line produces offer guarantee.
[summary of the invention]
The invention provides a kind of method that can quickly check large area Low-E film on coated glass defect.This method uses the film layer 2 of vapours attack coated glass of weak erosive, and in film layer 2, the erosive velocity at rejected region and other position is different and show different exterior appearance, thus the position of the judgement defect of quicklook and type.
The corrosive vapor that the method for this quick inspection large area Low-E film on coated glass defect uses is to be obtained by the heating of volatile liquid, steam can corrosive film layer, the membranous layer binding force of defective locations is relatively low and is easily fallen by steam corrosion, thus shows exterior appearance different with other normal position.The common used material that can produce this steam has citric acid, 84 disinfectant solution etc., and the injury to environment is the least.The consumption of citric acid or 84 disinfectant solution carries out suitable adjustment according to the difference of film layer, and adjusting foundation is that film layer is etched, but can not be etched completely.
In order to steam be preferably minimized the harm of personnel and environment, corrosion process is to carry out in airtight rustless steel casing.Casing is formed by entering water, water outlet, heating, control system, gas extraction system and glass frame 3.
The technological process of the present invention is:
Big glass sheet is cut into the small-shape 1 of uniform sizes, after mark position, is sequentially placed into glass frame 3 in order, glass film layers 2 down, with vertical direction angle 15～20 °；
Glass frame pushing away 3 and enters casing, box bottom places quantitative citric acid or 84 disinfectant solution, closes chamber door；
In casing, spray the hot water that a certain amount of temperature is 60～70 DEG C, stand 10～15 minutes；
Hot water is discharged, Air washer 5～10 minutes in casing；
Water is drained, takes out glass and carry out visual examination.
The present invention is the flood light about colour temperature 2700K for checking the light source of glass film layers visual condition.This light source is similar with illumination during sunrise sunset, it is possible to the most effective exterior appearance reflecting glass film layers, therefore can complete to check in Factory Building, it is not necessary to be moved to outside Factory Building.
The detection method advantage that the present invention provides is:
1, the present invention provides detection method is special standby be suitable for detecting strange land can the film layer defects of steel Low-E coated glass, it is not necessary to glass is carried out tempering process.
2, the detection method that the present invention provides substantially reduce strange land can detection time of steel Low-E film on coated glass defect, originally need the inspection that can complete for several hours, this method has only to can complete half an hour.
3, the detection method that the present invention provides can intuitively reflect whole film layer defects, including face scuffing, water droplet, air knife trace, bristle trace, sucker trace etc., even can reflect that tempering processes the film layer defects can't see, such as the face roller-way trace caused because of electrostatic charge absorption dust.
【Accompanying drawing explanation】
It is that schematic diagram placed by glass of the present invention shown in accompanying drawing.
