Abstract
A method for forming a lubricant layer on the surface of a glass and a method for manufacturing a glass using the same prevents scratches from occurring at the surface of a glass and decreases corrosion of glass manufacturing equipment. The method for manufacturing a glass includes forming a glass, supplying SO2 gas and a SO2 gas oxidation catalyst to the glass under an oxidation environment to form a lubricant layer at the lower surface of the glass, and annealing the glass.
Claims13
A method for manufacturing a non-alkali glass, comprising:
- forming a non-alkali glass;
- supplying SO2 gas and a SO2 gas oxidation catalyst to the non-alkali glass under an oxidation environment to form a CaSO4 lubricant layer at the lower surface of the non-alkali glass;
- and
- annealing the non-alkali glass.
A method for forming a lubricant layer on the surface of a non-alkali glass by using SO2 gas, wherein the SO2 gas is supplied to the non-alkali glass together with a SO2 gas oxidation catalyst under an oxidation environment.
