Document Type and Number:
Japanese Patent JPS6053831
Kind Code:
B2
Abstract:
PURPOSE:To provide a selective absorbing film on a glass simply by applying water glass on the glass base plate, applying grains having a selective-absorption characteristic to the outermost surface thereof, and then carrying out heating and drying to fix the grains. CONSTITUTION:Water glass 12 is coated on to an inner glass tube 2, and grains 13 having a selective-absorption characteristic are coated on to the water glass by a mechanical process such as rubbing. Thereafter, the tube 2 is heated at a temperature higher than 100 deg.C to evaporate the water contained in the water glass and solidify water glass. CuO derived from Cu powder heated in air is used as the selective-absorbing grain 13. According to this method, the selective-absorbing film may be formed simply on the inner glass tube 2 for a vacuum double glass tube collector.
