METHOD FOR MANUFACTURING LAYERED-FILM-BEARING GLASS SUBSTRATE

摘要

A method for manufacturing a laminated film-coated glass substrate in which a laminated film is formed on a glass ribbon by a CVD method by means of a plurality of injectors disposed in the annealing furnace, wherein: the laminated film is formed at Tg+50°C or lower; and in each of the injectors, if a quantity of heat exchanged between the injector and the glass ribbon is expressed by Q1 (kW), a quantity of heat exchanged between a heater paired with the injector and the glass ribbon is expressed by Q2 (kW), and an output of the glass is expressed by P (tons/day), then the relational expression |Q1|-P×0.116‰¤|Q2|‰¤|Q1| is satisfied.
