GLASS

Quartz infrared emitters areas of application in the Glass Industry :

● Heating

● Drying

● Coating

● Laminating

Many process stages in glass processing need heat. In an increasing number of cases, infrared heating technology offers excellent provision for solving the heating problems in these process stages, effectively and efficiently.

Preheating of laminated glass process

The manufacture and processing of laminated glass requires a few heating stages, which can be accomplished very well with infrared emitters. Lamination machine and autoclave is two of main equipment for laminated glass deep processing, the absorption rate of the glass at the infrared wavelength of 2.4um is only about 25%, while PVB foil’s can reach to 90% , it means the energy can be efficiently absorbed by the plastic foil. Medium-wave infrared lamp is an ideal wavelength for laminated glass applications.Twin tube medium-wave infrared radiators with gold coating are usually utilized and the length of the heating tube is normally about 3 meters, tube cross section will be 33*15mm for a better mechanical property.

Glass cutting machine

For laminated glass cutting, not only the cutting blade is required, but also an efficient heating method is required to complete the rapid softening of the intermediate plastic foil.

A fast response medium wave infrared emitter with gold reflector, heats the foil only in the small crack resulting from the glass breakage. The foils can then be easily separated by pulling them apart or with cutting tools. The infrared emitters usually is double tube but only one heating channel and 30 wide-angle directional heating for targeted directional heating, so as to achieve rapid melting of the laminated

Drying of Paint and Coating on Glass

Whether it’s a screen print on car windscreens, coatings on mirror backs or paint on decoration glass – the widest range of coatings on glass are dried reliably and in-line with infrared emitters. Infrared radiation penetrates into the material and dries the lacquer film from the inside outwards, skin- or blister formation on the surface is prevented and the drying of the lacquer or coating is speeded up. QUICKLY twin tubes can be produced in lengths of up to 6 meters and meet the maximum width of the mirror-making line. The result is a brilliant surface quality. Compared with warm air drying, time, space and energy are saved.
