Production of sheet glass |
摘要 |
Novel processes for the production of a smooth translucent glass sheet comprise grinding at least one face of a clear glass sheet using a conventional abrasive such as sand. Preferably the clear glass sheet is a sheet of clear float glass. The process may be carried out using a conventional glass grinding and polishing facility operated in a manner that the ground sheet is ground but not polished. The product preferably has a satin finish and a roughness Ra of less than 5.0 mu M and is sufficiently translucent as to be useful in privacy glazing. The ground glass products may have a haze value of from 80 to 90% and an Ra value of from 1.0 mu M to 3.0 mu M are believed to be novel. |
