With the fast development of building industry and glass manufacturing, glass deep processing industry has additionally developed extensively. This article mainly describes the wide application of flat glass washing machine in the glass industry.
1. Idea of glass washing machine
Because the special equipment applied in glass industry, glass washing machines are used for cleaning and drying original glass sheets. In accordance with cleaning method, it can 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 washing machine is major used for producing I.G. unit with aluminum spacer. The horizontal glass washing machine, though 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 washing machine
Now we majorly introduce the wide application of horizontal glass washing machine.
(1). Cleaning application for ordinary glass
The cleaning process of flat washer for ordinary glass is straightforward relatively. The tanks could be feed with industrial water without heating. Because the top of glass hasn’t been made any treatment, there is no special requirement for the brushes on the glass washer. At the same time, there is 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 horizontal vs vertical scaling. Once we clean the glass with thickness 3-19 mm, the look of distance between rollers can’t be viewed making too large. Generally, the factory might use middle or small washing machine to complete the cleaning and drying job 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 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 to be able to conveniently make the spacer bonding for the next steps, meanwhile, avoiding surface scratch. For most developed countries and areas on the planet, to be able to make the whole warm edge I.G.U, more and more factories adopt horizontal washing machine. This sort cleaning equipment consists of feeding section, washing section, drying section and output section and in the washing section, there are three tanks which feature of cycling heating water with the suitable PH (6-9), meanwhile, the device should be installed with good quality rubber transfer rollers in order to avoid glass scratching. Furthermore, engineers should design special air knife structure applied in drying element of the washer, such as for instance side-by-side multiple wind blade design, and guarantee the enough wind power and ensure it is adjustable, as the most effective drying result, the air blower can blow hot air. Every one of these considerations can perform the superb drying job: completely clearing up or blowing off water in multi-angle and much area. Please also note that to be able to match the total production line, the speed of glass washer also need to be regulated.
Remark: the production process of flexible spacer I.G. normally contains below machines: flat glass washing machine, 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. Round the production line, small assistant devices, such as for instance gas filling machine, duraseal spool stand will also be equipped.
(3).Cleaning application for coated glass
Before washing coating glass by the horizontal washing machine, we must take into consideration the choice of brush and water quality. In cleaning process, the coated glass sheets shouldn’t stop under brushes in order to avoid damaging the film. Because the hardness of each brush may differ, we must also check the film after cleaning to ensure that if the brush do some damage on the surface of glass or not. Once we clean the MSVD low-e coated glass, the simplest 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 technique may increase water corrosive, so we must test the sample water and confirm no effects occur. Furthermore, before large-scale production, we also have to do some trial production to determine that if the water can work very well in the system.
In real operation, solve the aforementioned problems, both horizontal glass washing machine and vertical glass washing machine 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 washing machine in order to complete their cleaning job. For the vertical washer, because of its structural limitations, it can’t suited to 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 washing machine
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 will 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 specific performance is that people aren’t only upgrade or improve the equipment structure, but also make the precise difference on brush manufacturing, choice of conveying rubber rollers, especially enable the studies of cleaning system and air knife structure meet different special requirements. We could expect, along with social development in future, more and more special glasses will come out and the horizontal washing machine would also be manufactured cooperatively using them and this industry will are more specific, detailed and standardized.Read More Other
