Problems solved by technology

Once the tightness of the tank body is not up to standard, it will cause low vacuum in the real tank, pollution and other problems, which will affect the quality of the material in the tank
[0003] Conventional double-sealing detection methods can only detect the structural size data of the double-sealing seal, and cannot evaluate the tightness of the double-sealing seal of the tank

Abstract

The invention provides a detection method and a detection device for the sealing performance of a tank, and relates to the technical field of metal packaging. The method and the device are used for detecting the sealing performance of a metal tank. The detection method comprises the following steps: immersing a to-be-detected end of the tank in an indicating liquid, and pressurizing the indicatingliquid and the tank; and determining the sealing performance of the to-be-detected end according to the indicating mark in the tank. The detection method disclosed by the invention can be used for visually and efficiently detecting the sealing performance of the metal tank.

Description

technical field [0001] The invention relates to the technical field of metal packaging, in particular to a detection method and detection device for the airtightness of a can body. Background technique [0002] Metal packaging has the advantages of good barrier properties, moisture resistance, light shading and sealing properties, so it can preserve the quality of the contents for a relatively long time and extend the shelf life of the contents. At present, double seaming technology is the mainstream technology of metal packaging. The double seaming technology is the operation of connecting and sealing the can body and the can lid or the bottom of the can. The technology of filling the seam of the double seam with sealant to ensure the airtightness of the tank body. Therefore, the double seam structure, the type of sealant and the amount of glue injected have an important impact on the sealing performance. Once the tightness of the tank body is not up to standard, it will ...
