Description

Technical Field

[0001] The utility model relates to the technical field of paint drying tests, in particular to a drying test device for coatings. Background Art

[0002] As is well known, different types of coatings have different drying time requirements. Drying tests can help determine whether the coatings meet the specified performance standards, such as hardness, surface smoothness, adhesion, weather resistance, etc.

[0003] For example, the Chinese utility model patent discloses a paint drying experiment device (publication (announcement) number CN218350162U), which relates to the field of paint performance testing devices. In this utility model, a multi-layer nested annular component contacts the sample to be tested from the outside to the inside, enabling multiple samples to be measured synchronously and conveniently exploring the different drying times of various coatings. Multiple test rings with different diameters and heights do not interfere with each other when contacting the sample, and the contact parts each time are completely different, avoiding the phenomenon of false adhesion. In addition, when the interval time of each lift of the carrier plate is known, the drying time can be easily calculated after the experiment by observing the adhesion conditions of different cotton strips and their corresponding positions. The annular component is set by hanging the test ring under the slide bar, which facilitates the reset of the test ring and the contact for multiple tests, and the overall structure is simple and firm. The magnet on the carrier plate can effectively adsorb the iron sample plate to prevent the sample plate from being misaligned during the contact test.

[0004] However, when the inventor specifically implemented this device, it was found that there were the following defects: the paint coated on the sample plate after the test often adhered to the sample plate, and it often took a large amount of manpower to clean it; or the sample plate was directly discarded, resulting in waste.
