Embodiment Construction

[0012] A method for testing adhesion of an aluminum alloy wheel paint film, comprising the following steps:

[0013] (1) Preparation tools: cutting knife, pressure-sensitive tape (with a pulling force greater than 800 grams), and an eraser;

[0014] (2) Mesh: Use a cutting knife to draw a grid on the part of the wheel to be tested. The relationship between the thickness of the paint film and the distance between the scratches is: the thickness of the paint film is ≤50um, and the distance between the scratches is 2mm; 50um 200um, scratch spacing is 5mm;

[0015] (3) Inspection: Stick the pressure-sensitive tape on the upper part of the grid, wipe the tape with an eraser to make it completely fit with the paint film, and then pull up the tape evenly;

[0016] (4) Judgment: Carefully observe the peeling situation at the intersection of the paint film grid, and judge the level of adhesion. The judgment standard is: special grade: no paint peeling off; first grade: peeling area les...

Description

technical field [0001] The invention relates to the technical field of aluminum alloy wheel paint film inspection, in particular to a method for inspecting the adhesion of aluminum alloy wheel paint film. Background technique [0002] Paint adhesion refers to the ability of the paint film to bond with the surface of the object to be coated or between coatings. Adhesion is an important technical index and a prerequisite for a series of properties of the paint film. The paint film with good adhesion is durable and has the performance required for use; the paint film with poor adhesion is easy to crack and fall off, making it unusable. Contents of the invention [0003] The object of the present invention is to provide a method for testing adhesion of aluminum alloy wheel paint film in order to make up for the deficiencies in the prior art. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A method for testing adh...
