Description

Technical Field

[0001] This utility model relates to the field of water-based insulating paint testing technology, and in particular to a device for testing the adhesion of water-based insulating paint. Background Technology

[0002] Water-based paint is a type of coating that uses water as a solvent or dispersion medium. It includes three types: water-soluble, water-dilutable, and water-dispersible. It has advantages such as water resistance, abrasion resistance, aging resistance, and salt spray resistance. Compared with other paints, water-based paint uses water as a solvent, and the adhesion of water-based paint is one of the key points of its testing. The adhesion of water-based paint is generally tested by using a cross-cut adhesion test device, which involves making a cross-cut on the sample with a cross-cut knife and testing the adhesion of the coating film with adhesive tape.

[0003] Existing water-based insulating varnish adhesion testing devices require manual scratch testing by the user during installation and use, which is cumbersome and makes it difficult to ensure that the depth of each scratch is consistent, affecting the testing results. The sample fixing process is also complicated and time-consuming, which increases the burden on the user and has certain adverse effects on the user experience. In order to overcome the shortcomings of the existing technology, we propose a water-based insulating varnish adhesion testing device. Utility Model Content

[0026] It should be noted that this utility model is a water-based insulating varnish adhesion testing device. When in use, the user places the sample coated with insulating varnish on the placement platform 1. By pulling open the movable limiting frame 11, a space for sample placement is created between the movable limiting frame 11 and the limiting frame 14. When the user releases the hand, the spring 13 rebounds, causing the length telescopic rod 12 to retract, which causes the movable limiting frame 11 to move towards the center of the placement platform 1, so that the sample can be clamped between the limiting frame 14 and the movable limiting frame 11, thus completing the fixation of the sample.
