It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the structural schematic diagram of the system for testing the purification performance of the coating provided by the embodiment of the present invention is applicable to the field of material performance evaluation, especially in the performance test of architectural coatings. The system for testing the paint cleaning performance in the embodiment comprises a test room 1, a movable wall 2 and a slide rail device 3 (such as a heavy ball guide), wherein the test room 1 is specifically enclosed by a floor 11, a ceiling and a multi-surface fixed wall 12, and the slide rail device 3 is installed on a bottom plate 11 in the test room 1. The number of the fixed walls 12 of the test room 1 can be determined according to actual conditions.
Further, the movable wall 2 is fixed on the slide rail device 3, so that the movable wall 2 can slide freely in the test room 1 through the slide rail device 3. And, when the movable wall 2 is assembled into the testing room 1 through the slide rail device 3, the movable wall 2 is matched with the fixed walls 12 of the testing room 1 (specifically, the fixed walls 12 at both sides of the movable wall 2), and the testing room 1 is partitioned into a first room 101 and a second room 102 which are sealed with each other, wherein the first room 101 is used for painting the paint, that is, the fixed wall 12 in the first room 101 is painted with the paint to be tested, and the second room 102 is used for being left empty as a contrast of the first room 101.
During testing, only the same amount of formaldehyde needs to be added into the first room 101 and the second room 102 (specifically, the formaldehyde can be generated by placing the plate pieces), then the gas in the first room 101 and the second room 102 is sampled, the corresponding formaldehyde concentration is obtained by detection, and then the detection parameters of the first room 101 and the second room 102 are compared, so that the purification performance (namely the formaldehyde purification performance) of the coating is obtained.
Because the first room 101 and the second room 102 are sealed by the sealing wall 2, the first room 101 and the second room 102 can be relatively sealed, so as to ensure the reliability of the detection parameters and avoid the influence on the formaldehyde concentration caused by the intercommunication of the gases in the first room 101 and the second room 102. In practical applications, the interior of the movable wall 2 may be hollowed out to reduce weight, or made of a plate material, but the sealing capability of the movable wall 2 should be ensured by using the plate material.
