摘要： PROBLEM TO BE SOLVED: To provide a method for treating the outer surface of a glass bottle, forming a coating film not so thick as to produce brightness and making the glass bottle have excellent alkali resistance and slight deterioration of resistance to scuffing even if the glass bottle used as a returnable bottle. SOLUTION: The outer surface of a glass bottle immediate after molding is treated with a fluorocarbon gas and then the outside of the glass bottle is treated with a tin compound and/or a titanium compound to form a coating film of tin oxide or titanium oxide having 80-400 Å thickness. The pinhole of the coating film is reduced and alkali resistance is improved by the treatment with the fluorocarbon gas.

摘要： PROBLEM TO BE SOLVED: To enable a metal mesh to be included into the center or a somewhat inner side of the front surface and back surface of a panel, in the inclusion of a metal mesh into a foamed glass panel to obtain a foamed glass composite panel. SOLUTION: This process for producing a composite panel composed of a foamed glass material and a single-stage metal mesh comprises a step to finely pulverize a glass raw material 3, a step to fill the powdery raw material and a metal mesh 2 in a mold 4, a step to foam the raw material by heating the mold, a step to slowly cool the heated mold and a step to separate the foamed glass composite material from the mold. In the above case, the metal mesh can be positioned at the center of the panel by positioning the mesh in the mold at a position slightly higher than the center of the raw material. In the case of including the metal mesh in two stages, the metal meshes are positioned above and below the raw material to obtain a composite panel containing the metal meshes at positions slightly depressed from the front surface and the back surface.

摘要： PROBLEM TO BE SOLVED: To provide a method for treating the outer surface of a glass bottle, affording a coating film not so thick as to shed luster, capable of giving the coating film high alkali resistance and having slight decline in the scratch resistance of the glass bottle even if it is used as a returnable bottle. SOLUTION: This method comprises depositing vaporized tin tetrachloride in an atmosphere at 200-450 deg.C on the outer surface of a glass bottle just after molded to form a tin oxide coating film on the outer surface. By setting the temperature of the vapor deposition atmosphere at 200-450 deg.C, the alkali resistance of the resultant coating film is improved and the glass bottle thus treated exhibits enough alkaliproof performance to be usable as a returnable bottle.

摘要： PROBLEM TO BE SOLVED: To achieve good drainage, and make hard to cause sagging by providing a slant surface inwardly inclined toward the inner circumference of an opening top surface, and forming a coating film consisting of two layers of a tin oxide film of a lower layer and a polyethylene film of a surface layer. SOLUTION: In glass vessel for storage of liquid, the opening top surface 2 of a glass bottle 1 is made in substantial horizontal plane, and a slope surface 3 inclined toward the inside of the inner circumference. The slope surface 3 is of a width of half or more the wall thickness of the uppermost part of the opening; however, it is preferable to be a width of at least 30% or more of the wall thickness. Thus, a coating film 7 consisting of two layers of a tin oxide film of a lower part layer and a polyethylene film of a surface layer is formed in the vicinity of the opening of a glass bottle including the top surface 2 and slope surface 3. In this manner, the coating film 7 is provided on both the top surface 2 and the slope surface 3 so as to impart water repelling, property so that a liquid content poured returns into the vessel not remaining at the top part thereof.

摘要： PROBLEM TO BE SOLVED: To provide a glass container which is inexpensively manufacture using a conventional glass container manufacturing facility, free from any toxicity for a human body, and excellent in liquid repellency. SOLUTION: An inwardly inclined surface is formed on an inner circumference of a zenith surface of a mouth part, and a tin oxide film or a titanium oxide film is formed close to the mouth part including the zenith surface and the inclined surface. The liquid content easily returns into a container by the action of the inclined surface, water repellency is given to the mouth part by the tin oxide film or the titanium oxide film, and the liquid release is excellent. Since a coating layer is formed on the mouth part using a coating facility and a material which have been used for a body part of a glass container, the coating layer can be formed inexpensively and safely, and no problems to a human body are raised since the coating film is formed of tin oxide or titanium oxide.

摘要： PROBLEM TO BE SOLVED: To provide a new glass foam composite body having strength capable of making a large-scaled one excellent in heat resistance, fire resistance, heat insulating efficiency, sound absorbing efficiency and form stability. SOLUTION: A glass foam composite body, is so constituted that a metal reinforcing material is composed in the inside of a glass foam. In that case, as the metal reinforcing material, metals formed in the shape of a straight line, net, coil, etc., are favorable. While taking over excellent heat resistance, fire resistance, durability, heat insulating efficiency, sound absorbing efficiency of the glass foam as they are, since strength is increased by the metal reinforcing material, a large-scaled and stabilized form can be made. Accordingly, it is formed in the shape of a panel or a block, and it can be used as excellent building material such as walling, flooring, ceiling material, etc.

摘要： PROBLEM TO BE SOLVED: To simply and rapidly measure a film thickness compared to a film thickness measuring method by a conventional hot coating meter and to enable to rapidly check in a bottle producing process. SOLUTION: The film thickness is measured more simply and rapidly than the film thickness measuring method by the conventional hot coating meter by utilizing that the logarithm of electric resistance of the oxide coated film on the glass bottle is in proportion with the film thickness to measure and control the film thickness. Since the measurement and control by the method is easily automated in the bottle production process, all glass bottles are enabled to be measured and the film thickness is controlled more accurately than the conventional one without operators.
