際上不可能であった。(Prior Art) It has been known to form a glass layer by thermally spraying fine glass powder onto the surface of a material having a higher melting point than glass, such as metal. (Special Publication No. 30-2609, Special Publication No. 56-
21737, Utility Model Publication No. 50-43532), however, when forming the above-mentioned glass layer, if the material to be formed has a lower melting point than that of glass, the surface of the glass layer may be lower than that of molten glass. It was practically impossible to form a glass layer because there was a risk that the glass would melt or burn due to the radiant heat of the glass.

The surface of the object to be formed is coated with melted fine glass powder, which easily imparts smoothness, hardness, decorative properties, corrosion resistance, optical properties, and insulation properties to the object. It is possible. Moreover, plastics, woven fabrics, etc., which have a lower melting point than glass, can be used as the material on which the glass film is formed.

The one shown in FIG. 1 uses an air flow as the constant velocity gas flow, and this may be used instead of an inert gas. (1) is a glass fine powder thermal spraying device, which, as is well known, sends fine powder glass (1 voice range to 5 days diameter) from a central tube and blows it into the surrounding hot air (700 to 800℃,
(1 to 105 seconds) while melting the surface of the fine glass powder. (3) is an air flow (constant velocity for 1 to 55 seconds), with an air curtain blowing downward, and an air flow layer with a thickness of 1 to 50 cIrL), 200°C ± 1
Maintain 50°C. (4) is a beam of fine glass powder ejected from the nozzle (2), which adheres to the fiber layer of the woven fabric (5) and is called wetting. ) Forming glass 1e.

The fine powder is welded to the surface, but the air curtain layer (3
), the radiant heat of the molten glass discharged from the nozzle (2) is blocked and does not reach the surface of the glass film-formed object (5), so there is no risk of melting or burning the surface. A glass layer of a required thickness is then formed on the surface of the woven fabric (5).

2) The molten glass fine powder beam (4) is injected onto the surface of the object to be formed, and at the same time, a vertical air flow is blown onto the surface of the object, and the radiant heat of the molten glass is absorbed by the air layer. At the same time, a glass layer is formed by the molten fine powder glass passing through the air layer.
