Description

Technical Field

[0001] The invention relates to an experimental device for measuring the leveling and sagging of coatings. Background Art

[0002] Paint iron is composed of paint film and thin plate substrate. Its production process includes three processes: paint coating, wet film leveling and paint curing. After the coating process, the paint and thin plate substrate form a paint film on the surface of the substrate. The paint film is in a flowing state, which is called wet film paint iron. Before flowing into the paint curing process, the paint film of the wet film paint iron must achieve good flatness, so that it can form a good surface quality after the paint is cured. When the wet film paint iron completes the flow process, the thin plate substrate will be horizontal or tilted at a certain angle, and different tilt angles affect the flatness of its wet film surface. According to the rheological principle of coatings, when the wet film paint iron is placed horizontally, the paint film will only level; when the wet film paint iron is placed vertically or tilted, the paint film will sag and level at the same time; leveling and sagging affect the surface flatness of the wet film paint iron. Thickeners can increase the viscosity of the coating system, and the main function of leveling agents is to increase the fluidity of the coating. In fact, whether the fluidity is too large or too small, it will lead to defects. If the leveling is too small, the coating cannot level well, which will greatly affect the appearance of the paint film, making it rough and glossy; if the leveling is too large, it will cause sagging. Therefore, choosing the right balance between leveling and sagging before production can solve this problem.

[0003] Existing laboratories use devices to observe paint leveling and sagging that are simply set up with a flat plate and an inclined plate. After the paint film is formed, it is artificially shaken to simulate transverse waves or longitudinal waves in the flow environment. The amplitude and strength of each shake cannot be guaranteed to be consistent, resulting in inaccurate experimental results. In addition, the inclined plate cannot be easily adjusted in angle in a timely manner, making it extremely inconvenient to use. Summary of the invention
