本発明は、金属板をガラス質素材で被覆し、金属母材の
腐蝕或いは金属異物による内容物の汚染を防止するガラ
スライニングのピンホール補修方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is for pinhole repair in glass lining, which covers a metal plate with a glass material to prevent corrosion of the metal base material or contamination of the contents by metal foreign matter. Regarding the method.

途に使用される場合は特にこの傾向が著しい。一般には
、容器内面にガラスライニングを施して保護している。Storage containers, reaction vessels, stirring blades, pipes, and other accessories that come into contact with corrosive chemicals are manufactured from steel plates and the like due to their advantages in weight, hardness, workability, and the like. However, steel sheets are easily attacked by acids, alkalis, and other corrosive chemicals, especially when used in heating applications. Generally, the inner surface of the container is protected by a glass lining.

のパツキン４を介して螺着している。However, glass is extremely vulnerable to impact, and cracks and pinholes inevitably occur during use, and chemicals penetrate into the base material through these locations and corrode the base material. Therefore, pinholes are repaired as soon as they are discovered. As shown in FIG. 2, a bolt 3 made of tantalum and having a hemispherical shielding bowl 2 in close contact with the head thereof is screwed into a pinhole 1 via a packing 4 made of Teflon resin.

められていた。According to this method, the bolt 3 becomes loose due to repeated heating and cooling and vibration during use, and corrosive liquid enters through the small gap created between the packing 4 and the glass surface 5 and corrodes the base material. However, the service life is short, and as a result, the number of corrosion areas is actually increased. Therefore, there was a need for a more durable glass-lined pinball repair method.

物焼結体で被覆したことを特徴とする。The present invention aims to solve the above-mentioned problem, and has a structure in which a bolt, at least the surface of which is made of a corrosion-resistant metal, is screwed into a pinhole that has occurred in the glass lining surface to close the pinhole. It is characterized in that the portion and its surroundings are coated with a corrosion-resistant plastic, a corrosion-resistant metal, or a corrosion-resistant metal oxide sintered body.

The corrosion-resistant coating is preferably a fluorocarbon resin, and a polymer of a fan-containing organic monomer such as polytetrafluoroethylene, polyfluoroethylenepropylene, perfluoroalkoxy group copolymer, tetrafluoroethylene-ethylene copolymer, or a copolymer thereof. A copolymer with a capable monomer is used and sintered onto the glass lined surface.
