With the fast development of building industry and glass manufacturing, glass deep processing industry in addition has developed extensively. This information mainly describes the wide application of flat glass washer in the glass industry.
1. Concept of glass washer
While the special equipment applied in glass industry, glass washing machines are employed for cleaning and drying original glass sheets. According to cleaning method, it may 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 washer is major employed for producing I.G. unit with aluminum spacer. The horizontal glass washer, although it takes more area, has been applied in more extensive fields because of its more high efficiency and excellent structure.
2. Wide application of flat glass washer
Now we majorly introduce the wide application of horizontal glass washing machine.
(1). Cleaning application for ordinary glass
The cleaning means of flat washer for ordinary glass is simple relatively. The tanks could be feed with industrial water without heating. Because the outer lining of glass has not been made any treatment, there’s no special requirement for the brushes on the glass washer. At the same time, there’s also no too restrictive requirement for water PH. In regards to the air knife design, we could adopt normal structural but must ensure the wind power could be adjusted. Whenever we clean the glass with thickness 3-19 mm, the style of distance between rollers can’t be considered making too large large vertical vs horizontal scaling. In most cases, the factory might use middle or small washer to complete the cleaning and drying work for raw 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 example 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 to be able to conveniently make the spacer bonding for these steps, meanwhile, avoiding surface scratch. For many developed countries and areas in the world, to be able to make the whole warm edge I.G.U, more and more factories adopt horizontal washing machine. This sort cleaning equipment is composed 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 equipment must certanly be installed with top quality rubber transfer rollers to prevent glass scratching. Additionally, engineers should design special air knife structure applied in drying part of the washer, such as for example side-by-side multiple wind blade design, and guarantee the enough wind power and make it adjustable, as the very best drying result, the air blower can blow hot air. Each one of these considerations can perform the excellent drying job: completely cleaning up or blowing off water in multi-angle and much area. Please also remember that to be able to match the sum total production line, the speed of glass washer also have to be regulated.
Remark: the production means of flexible spacer I.G. normally contains below machines: flat glass 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 in order to complete hot-press sealing job in heated roller machine. Around the production line, small assistant devices, such as for example gas filling machine, duraseal spool stand may also be equipped.
(3).Cleaning application for coated glass
Before washing coating glass by the horizontal washer, we should take into consideration the decision of brush and water quality. In cleaning process, the coated glass sheets should not stop under brushes to prevent damaging the film. While the hardness of each brush may vary, we should also check the film after cleaning to confirm when the brush do some damage on the surface of glass or not. Whenever we clean the MSVD low-e coated glass, the easiest way is not 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 technique may increase water corrosive, so we should test the sample water and confirm no effects occur. Additionally, before large-scale production, we also must do some trial production to determine when the water can work well in the system.
In real operation, solve the above problems, both horizontal glass washer and vertical glass 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 features of large size, thickness and weight, factories often use horizontal washer in order to complete their cleaning job. For the vertical washer, because of its structural limitations, it can’t suitable for washing large size glass. In the form of 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 washer
Within the last decade, building glass has been developed in the direction of insulating, energy-saving, safety and decoration, therefore the horizontal washing machines may also be improved with the exact same direction. Particularly after the solar glass, conductive glass, foam glass and other special glass are widely placed into market, the factoies put forward higher cleaning requirements to above special glass. The particular performance is that individuals are not only upgrade or improve the gear structure, but in addition make the precise difference on brush manufacturing, collection 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 with social development in future, more and more special glasses will come out and the horizontal washer would also be manufactured cooperatively using them and this industry will be specific, detailed and standardized.
