With the fast development of building industry and glass manufacturing, glass deep processing industry has also developed extensively. This short article mainly describes the wide application of flat glass automatic washer in the glass industry.
1. Notion of glass automatic washer
Since the special equipment applied in glass industry, glass washing machines are useful for cleaning and drying original glass sheets. In accordance with cleaning method, it could be distinguished vertical glass washer(vertical glass washing machine) and horizontal glass washer. Due to the limitation of glass size and vertical structural, at present vertical glass automatic washer is major useful for producing I.G. unit with aluminum spacer. The horizontal glass automatic washer, although it takes more area, has been applied in more extensive fields due to the more high efficiency and excellent structure.
2. Wide application of flat glass automatic washer
Now we majorly introduce the wide application of horizontal glass washing machine.
(1). Cleaning application for ordinary glass
The cleaning procedure for flat washer for ordinary glass is easy relatively. The tanks may be feed with industrial water without heating. Because the surface of glass hasn’t been made any treatment, there is no special requirement for the brushes on the glass washer. At the same time frame, there is also no too restrictive requirement for water PH. Concerning the air knife design, we could adopt normal structural but must ensure the wind power may be adjusted scale out vs scale up. Once we clean the glass with thickness 3-19 mm, the style of distance between rollers can’t be viewed making too large. Generally speaking, the factory can use middle or small automatic washer to accomplish the cleaning and drying job for raw little bit of ordinary glass.
(2).Cleaning application for warm-edge insulating glass
For the production of warm edge insulating glass (with flexible spacer, such as for instance duralite or duraseal or superspacer), the cleaning requirements to the raw glass sheets are higher. Operators should ensure the good cleaning and drying for surface in order to conveniently make the spacer bonding for the following steps, meanwhile, avoiding surface scratch. For most developed countries and areas on earth, in order to make the entire warm edge I.G.U, more and more factories adopt horizontal washing machine. This kind cleaning equipment consists of feeding section, washing section, drying section and output section and in the washing section, you can find three tanks which feature of cycling heating water with the suitable PH (6-9), meanwhile, the machine must certanly be installed with high quality rubber transfer rollers in order to avoid glass scratching. Furthermore, engineers should design special air knife structure applied in drying area of the washer, such as for instance side-by-side multiple wind blade design, and guarantee the enough wind power and allow it to be adjustable, as the best drying result, the air blower can blow hot air. All these considerations can achieve the excellent drying job: completely cleaning up or blowing off water in multi-angle and much area. Please also observe that in order to match the sum total production line, the speed of glass washer also have to be regulated.
Remark: the production procedure for flexible spacer I.G. normally contains below machines: flat glass automatic washer, flexible spacer assembly table, glass assembly table, heated roller press machine and glass convey table. Total production line has two-side or single side establishment. Glass is conveyed to glass washer in the horizontal state then starts its first process until to finish hot-press sealing job in heated roller machine. Round the production line, small assistant devices, such as for instance gas filling machine, duraseal spool stand may also be equipped.
(3).Cleaning application for coated glass
Before washing coating glass by the horizontal automatic washer, we must consider the choice of brush and water quality. In cleaning process, the coated glass sheets should not stop under brushes in order to avoid damaging the film. Since the hardness of each brush may vary, we must also check the film after cleaning to ensure when the brush do some damage on the surface of glass or not. Once we clean the MSVD low-e coated glass, the easiest way isn’t to make use of recycled water, since these films are extremely sensitive to the PH value, if using recycled water, operators should monitor water PH value constantly.
Using demineralization or deionization water to spray coated glass to guarantee no residue when drying glass. However, the technology of this method may increase water corrosive, so we must test the sample water and confirm no adverse reactions occur. Furthermore, before large-scale production, we also should do some trial production to find out when the water can work nicely in the system.
In real operation, solve the aforementioned problems, both horizontal glass automatic washer and vertical glass automatic washer can well complete cleaning and drying job to coated glass
(4). Cleaning application for other glass (such as tempered, laminated and safety glass)
As above glass top features of large size, thickness and weight, factories often use horizontal automatic washer to finish their cleaning job. For the vertical washer, due to the structural limitations, it can’t ideal for washing large size glass. Through choosing appropriate soft brushes and using different air knife structure, the horizontal glass washer can meet with the washing and drying demand for above glass.
3. Prospect of horizontal automatic washer
Within the last few decade, building glass has been developed in the direction of insulating, energy-saving, safety and decoration, so the horizontal washing machines may also be improved with the same direction. Particularly after the solar glass, conductive glass, foam glass and other special glass are widely put in market, the factoies put forward higher cleaning requirements to above special glass. The precise performance is that individuals are not only upgrade or improve the gear structure, but additionally make the particular difference on brush manufacturing, selection of conveying rubber rollers, especially enable the studies of cleaning system and air knife structure meet different special requirements. We are able to expect, along side social development in future, more and more special glasses can come out and the horizontal automatic washer would also be manufactured cooperatively using them and this industry will be much more specific, detailed and standardized.No comments
