Method and apparatus for forming tempered sheet glass with a pyrolytic film in a continuous process |
摘要 |
A method and apparatus for filming and tempering a pre-cut glass sheet in a continuous process. The glass sheet is heated initially to a temperature sufficient for pyrolysis. The heated glass is sprayed with a coating composition which reacts with the glass to form a metal oxide film on its surface. The filmed glass is re-heated to both restore the heat lost by spraying and to bring its temperature to a level sufficient for tempering. The glass sheet is then tempered by subjecting it to rapid cooling. The method can be modified to include a secondary spraying wherein after the glass is first sprayed it is re-heated as in the initial step and then re-sprayed before completing the process. Apparatus for carrying out the above described method is also disclosed.
