Description

The ER-4 multifunctional digital enamel rater is equipment for testing whether there are perforations in the anti-corrosion coating layer of metal cans and lids. Various containers, lids and tinplate anticorrosive coatings can be inspected after changing a variety of testing molds and brackets. The ER-4 multifunctional digital enamel rater is a widely used testing instrument in the canning industry.

The Working Principle of ER-4 Multifunctional Digital Enamel Rater for Metal Cans and Lids
• Testing of Anti-corrosion Coatings for Round Cans and Irregular Cans

The Working Principle of ER-4 Multifunctional Digital Enamel Rater for Metal Cans and Lids 1

As shown in the picture above, put the can body on the test stand. Put electrolyte (for example: sodium chloride solution, brine) in the can body. Electrolyte is used as one electrode, and the outer surface or bottom of the can body is used as the other electrode. Power ups. If the paint layer in the can body wall is perforated, the current is very large. The degree of perforation of the paint layer in the can body wall is judged by measuring the current value.

The Working Principle of ER-4 Multifunctional Digital Enamel Rater for Metal Cans and Lids 2

As shown in the picture above, put electrolyte (for example: sodium chloride solution, brine) in the water box. Put the lid on the lid hole on the water box. The diameter of lid hole is slightly smaller than the lid and varies according to the shape of the lid. Let the pressing device fix the lid, and draw out the air in the water box to make the water box form a vacuum. At this time, the lid tightly touches the edge of the lid hole. Turn the water box so that the lid hole faces the bottom (there is a sealing rubber ring between the lid and the lid hole to prevent water leakage). The electrolyte is used as one electrode, and the outer surface of the metal lid is used as the other electrode. Power ups. If the paint layer of the lid is perforated, the current is very large. The degree of perforation of the paint layer on the metal lid is judged by measuring the current value.

• Testing of anticorrosive paint layer of tinplate sheet

As shown in the figure above, the testing process and principle of the anticorrosive coating layer of the tinplate sheet are the same as the testing process and principle of the lid. Of course, the area of the tinplate sheet is larger than that of the lid.

Features of ER-4 Multifunctional Digital Enamel Rater for Metal Cans and Lids
● It can test different shapes of can bodies, lids and tinplate sheets, and has a wide range of applications.
● The testing operation is simple and fast.
● Optimized electrical design, more sensitive, reliable and accurate.
● Corrosion resistant.
● The buttons are made of film, which is more durable and corrosion resistant
● Press the "Inverting" button to invert the detected DC electrode, so as to observe the bubbles generated by the "metal exposed point", so as to accurately determine the position of the "metal exposed point".
