Embodiment 1

[0037] Embodiment 1 detects the corrosion resistance of the coated iron used for packing luncheon meat

[0038] Use a kind of device of the present invention to be used for detecting the corrosion resistance of packing material to detect, and this device comprises electrochemical workstation, nitrogen tank, air collecting device and figure 2 The electrolytic cell shown.

[0039] 1) Preparation of samples and standard sheets

[0040] Cut the coated iron into a sample whose outer peripheral edge coincides with the lower edge of the side wall, clean with alcohol to remove surface oil stains and sundries, then clean and dry with distilled water, and use it as a working electrode after welding the lead wire. The method may be, for example, to set a working electrode lead wire outlet on the base, so that the working electrode lead wire can be drawn out from the side of the coated iron sample to be detected that is not in contact with the electrolyte through the working electrode l...

Abstract

The invention provides an electrolytic tank for detecting corrosion resistance of a packing material. The electrolytic tank is sealed and provided with an upper cover and a cylindrical side wall, and takes a to-be-detected metal packing material, serving as a working electrode, as a bottom; the electrolytic tank is internally provided with electrolyte; a sealing ring is respectively arranged between the bottom and the side wall, as well as between the side wall and the upper cover to seal the electrolytic tank; the distance from the lower end of a reference electrode to the bottom is at least 1mm; a counter electrode is ring-shaped, and is arranged in the electrolyte and parallel to the bottom; the reference electrode is positioned in the center of the ring; the distance from the ring-shaped counter electrode to the surface of the electrolyte is one second or two thirds depth of the electrolyte, and the distance from the ring-shaped counter electrode to the bottom is not greater than the distance from the reference electrode to the bottom; and the upper cover is also provided with an inert gas inlet pipe and an air outlet pipe. The electrolytic tank can be used for imitating the actual use conditions of the packing material and reducing system error during detection; and the detected packing material can be re-utilized.

Description

technical field [0001] The invention relates to an electrolytic cell, in particular to an electrolytic cell for testing the corrosion resistance of packaging materials. Background technique [0002] Coated or film-coated metal packaging materials have been widely used in the food and beverage industry as replacement packaging materials, such as packaging materials for various fruit juices, tea drinks, milk, tomato sauce, luncheon meat and other products. With the increasing attention to safety issues, in addition to the quality of food or beverage itself, the safety of metal packaging materials used to package food or beverages has also become one of the issues of concern, the most prominent of which is the detection of metal packaging materials on the packaged items. How is the corrosion resistance. [0003] Before using metal packaging materials to pack food or beverages, it is necessary to detect the corrosion resistance of the packaging materials. Currently, the commonl...
