Wide Application of Horizontal Washing Machine Used in Glass Industry

With the fast development of building industry and glass manufacturing, glass deep processing industry has also developed extensively. This article mainly describes the wide application of flat glass washing machine in the glass industry.

1. Concept of glass washing machine

As the special equipment applied in glass industry, glass washing machines are used for cleaning and drying original glass sheets. According to cleaning method, it can be distinguished vertical glass washer(vertical glass washing machine) and horizontal glass washer. Because of 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, 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 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 simple relatively. The tanks can be feed with industrial water without heating. Because the surface of glass has not 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. About the air knife design, we can adopt normal structural but must ensure the wind power can be adjusted. When we clean the glass with thickness 3-19 mm, the design of distance between rollers can not be considered making too large. Generally speaking, the factory could use middle or small washing machine to do the cleaning and drying job for raw piece 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 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 in the world, in order to make the entire warm edge I.G.U, more and more factories adopt horizontal washing machine. This kind cleaning equipment is composed 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 machine must be installed with high quality rubber transfer rollers to avoid glass scratching. In addition, engineers should design special air knife structure applied in drying section of the washer, such as side-by-side multiple wind blade design, and guarantee the enough wind power and make it 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 note that in order 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 to finish hot-press sealing job in heated roller machine. Around the production line, small assistant devices, such as gas filling machine, duraseal spool stand are also equipped.
