摘 要:
PURPOSE: To impart a high preventing effect against elution of alkali to a glass container at a low treating cost by treating the glass container with a treating liquid containing hydrosilicofluoric acid in which silicon dioxide is in a supersaturated state. ;CONSTITUTION: A glass
container is brought into contact with a treating liquid containing hydrosilicofluoric acid in which silicon dioxide is in a
supersaturated state. By this method, a silicon dioxide film is formed on at least the inner surface to be in contact with contents of the glass container so as to prevent elution of the component in the glass into contents. In this case, by heat treating the film after formed, the film can be made dense to impart a higher effect to prevent elution of alkali. The heat treatment temp. is preferably high in the range below the strain point of the glass. The silicon dioxide film is preferably ≥30nm thick.;COPYRIGHT: (C)1995,JPO 主权项:
