Abstract
PURPOSE: After base material coated with alkali silicate or glass film on the surface is stood in a humid atmoshphere containing a specific gas, it is washed with water, thus producing product coated with glass film that does not develop efflorescence.
CONSTITUTION: A material of metal as aluminum or copper is coated with an aqueous solution of alkali silicate and dried at 150W160°C so that the coated film of the alkali silicate is formed on the surface with a thickness of less than 5 microns. Then, the film is baked at a temperature lower than 400°C into glass film. Then, the product is stood in a humid atmosphere that the relative humidity is about 80% and contains 0.01W5% of at least one gas selected from sulfur dioxide, carbon dioxide and nitrogen dioxide to make the film react with the gas and to force the reaction product to migrate on the film by the humidity, resulting in development of efflorescence. Then, the film is washed with water to remove the efflorescence.
