Abstract

The invention discloses a method for in-situ detecting inner wall corrosion of a metal food packaging can. By adopting the method, in-situ online detection can be performed in the inner wall corrosionprocess of the metal food packaging can. The method is easy and convenient to use and operate, is stable and accurate in measurement data, and is suitable for metal food packaging cans of various sizes and specifications.

Description

[0001] The application of the present invention is a divisional application of the parent application "An in-situ detection device and method for evaluating the corrosion of the inner wall of metal food packaging cans". The application date of the parent application is July 22, 2016. The application number is 2016105987305. technical field [0002] The invention relates to an in-situ corrosion detection technology, in particular to a method for in-situ detection of corrosion on the inner wall of a metal food packaging can. Background technique [0003] Metal packaging materials are mainly divided into two categories: steel and aluminum; and each category contains several varieties, each with its own scope of application. Compared with other metal packaging materials, steel has certain advantages. Steel is rich in sources, low in energy consumption and cost, and still occupies the first place in metal packaging materials. The steel used for packaging is mainly low-carbon th...
