Description

Technical Field

[0001] This utility model relates to the technical field of coating testing devices, and in particular to a paint scrub resistance tester suitable for interior and exterior walls. Background Technology

[0002] The washability of paint is a key indicator of the quality of interior and exterior wall coatings, directly affecting the durability of the wall's decorative effect and its service life. A paint washability tester suitable for both interior and exterior walls functions by simulating everyday washing actions to determine the washability of paint applied to walls or test samples. Sampling and testing within a sandbox is a crucial step in this test. Specifically, representative areas are selected within a pre-prepared test sandbox coated with the target paint, and different sample walls are simultaneously washed until the paint layer shows damage or peeling. The number of washes is recorded, thus completing the evaluation of the paint's washability.

[0003] In existing technologies, when testing the washability of interior and exterior wall coatings, a sampling method is usually used to simultaneously test different interior and exterior wall coatings. However, in actual use, existing wall sample placement is not convenient enough, and the lifting and lowering of the sample cannot be adjusted well according to the thickness of the wall and coating. The lifting and lowering method of the sample lacks flexibility, which affects the accuracy of the test results. Furthermore, the disassembly and assembly operations are not convenient, and the initial installation and subsequent disassembly operations are inconvenient. Therefore, we propose a paint washability tester suitable for interior and exterior walls to solve the above problems. Utility Model Content
