Description

Technical Field

[0001] The utility model relates to the technical field of corrosion repair, in particular to a surface pitting corrosion repair device. Background Art

[0002] After long-term use, corrosive liquids will drip onto the surface of the industrial gas generator, causing pitting corrosion. Pitting corrosion is a very serious problem. The amount of metal lost due to corrosion worldwide accounts for about 10% of its annual output each year, and the amount of metal lost due to corrosion in industrial gas generators is also 8% of its original weight. Pitting corrosion not only shortens the service life of industrial gas generators and causes economic losses, but also easily leads to various accidents, threatening safe production. After serious pitting corrosion occurs on the surface of the industrial gas generator, a repair device is required to use polishing to remove the corroded part, and then spray an anti-rust coating to repair the corrosion. However, the common surface pitting corrosion repair devices on the market are generally wider when stored, which is inconvenient to store and will take up a large space. In addition, during the repair process, the metal powder generated will spread to the surrounding area, making it difficult to collect and affecting the health of the staff. Utility Model Content
