Wide Application of Side to side Washer Used in Glass Industry

With the fast development to build industry and glass manufacturing, glass deep processing industry in addition has developed extensively. This article mainly describes sandton glass and aluminium the wide application of flat glass washer in the glass industry.

  1. Notion of glass washer

As the special equipment applied in glass industry, glass washers are used for cleaning and blow drying original glass sheets. According to cleaning method, it can be recognized top to bottom glass washer(vertical glass washing machine) and side to side glass washing machine. Because of the restriction of glass size and top to bottom structural, at present top to bottom glass washer is major used for producing I. F. unit with aluminum spacer. The side to side glass washer, although it takes more area, has been applied in more extensive fields due to its more high efficiency and excellent structure.

  1. Wide application of flat glass washer

Now we majorly introduce the wide application of side to side glass washer.

(1). Cleaning application for ordinary glass

The cleaning process of flat washing machine for ordinary glass is easy relatively. The tanks can be feed with industrial water without heating. Because the surface of glass isn’t made any treatment, there is no special dependence on the brushes on the glass washing machine. At the same time, there is also no too restricted dependence on water PH. About the air cutting knife design, we can adopt normal structural but must be sure the wind power can be adjusted. When we clean the glass with thickness 3-19 mm, the design of distance between rollers can’t be considered making too large. Generally speaking, the manufacturing unit could use middle or small washer to do the cleaning and blow 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 duralite or duraseal or superspacer), the cleaning requirements to the raw glass sheets are higher. Operators should ensure the good cleaning and blow drying for surface in order to suitably make the spacer bonding for the following steps, meanwhile, avoiding surface scratch. For most developed countries and areas in the world, in order to make the entire warm edge I. F. You, more and more plants adopt side to side washer. This sort cleaning equipment comprises feeding section, washing section, blow 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 cutter must be installed with high quality plastic transfer rollers to avoid glass marring. In addition, engineers should design special air cutting knife structure applied in blow drying section of the washing machine, such as side-by-side multiple wind blade design, and guarantee the enough wind power and make it adjustable, as the best blow drying result, the air blowing apparatus can blow hot air. All these considerations can perform the superb blow drying job: completely cleaning up or coming off water in multi-angle and much area. Please also note that in order to match the sum of production line, the speed of glass washing machine also need to be regulated.

Comment: the production process of flexible spacer I. F. 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 communicated to glass washing machine in the side to side state then starts its first process until to finish hot-press securing job in heated roller machine. Around the production line, small associate devices, such as gas filling machine, duraseal spool stand are also equipped.

(3). Cleaning application for sprayed glass

Before washing coating glass by the side to side washer, we should consider the choice of brush and water quality. In cleaning process, the sprayed glass sheets should not stop under brushes to avoid damaging the film. As the firmness of each and every brush may be different, we should also check the film after cleaning to confirm that if the brush do some damage on top of glass or not. When we clean the MSVD low-e sprayed glass, the best way is not to use recycled water, because these films are very sensitive to the PH value, if using recycled water, operators should monitor water PH value constantly.

Using demineralization or deionization water to apply sprayed glass to make sure no remains when blow drying glass. However, the technology of this process may increase water corrosive, so we should test the sample water and confirm no effects occur. In addition, before large-scale production, we also have to do some trial production to determine that if the water can work well in the system.

In real operation, solve the above problems, both side to side glass washer and top to bottom glass washer can well complete cleaning and blow drying job to sprayed glass

(4). Cleaning application for other glass (such as tempered, laminated and safety glass)

As above glass features of large size, thickness and weight, plants often use side to side washer to finish their cleaning job. For the top to bottom washing machine, due to its structural limitations, it can not suitable for washing large size glass. By means of choosing appropriate soft brushes and using different air cutting knife structure, the side to side glass washing machine can fulfill the washing and blow drying demand for above glass.

  1. Prospect of side to side washer

Within the last few decade, building glass has been developed in the direction of insulating, energy-saving, safety and decoration, so the side to side washers are also improved with the same direction. Particularly after the solar glass, conductive glass, foam glass and other special glass are widely put into market, the factoies put forward higher cleaning requirements to above special glass. The actual performance is that we are not only upgrade or increase the equipment structure, but also make the actual difference on brush manufacturing, selection of offerring plastic rollers, especially enable the studies of cleaning system and air cutting knife structure meet different special requirements. We can expect, along with social development in future, more and more special glasses will come out and the side to side washer would also be manufactured cooperatively with them and this industry will become more specific, detailed and standard.
