Abstract
PURPOSE: To rapidly substitute a predetermined gas for air in the hollow layer between double-layer glass plates whose peripheral parts are airtightly joined with a sealing material and to enhance the substitution rate by exhausting the air to a vacuum and by feeding the gas while controlling the press. rising speed in the hollow layer to below a specified value.
CONSTITUTION: Four sides of glass plates 1,2 set at a space are sealed with sealing material 3 to form double-layer glass 11 having hollow layer 4. Air in layer 4 is exhausted through thin tube 5 of glass 11 with vacuum pump 6 to reduce the press. to below 10 millibars, and valve 7 is closed. Next predetermined gas 10 such as Ar gas is fed into layer 4 through thin tube 8 piercing opposite sealed side 3 while regulating control valve 9 so that the press. rising speed in layer 4 becomes below 200millibars/sec. By this method the gas substitution rate in layer 4 can easily be raised to above 90% without damaging the glass and material 3.
