Description

Technical Field

[0001] The utility model relates to the technical field of decorative plate detection, in particular to a rapid detection device for detecting the formaldehyde release amount of decorative plates. Background Art

[0002] Decorative board is a kind of man-made board. It is a thermosetting laminated plastic made of a variety of special papers after chemical treatment and high-temperature and high-pressure adhesive. The board surface has various wood grains or patterns, is bright and smooth, and has bright and beautiful colors. At the same time, it has good physical properties such as high wear resistance, heat resistance, cold resistance, and fire resistance. It is often used in store decoration. In order to protect human health, it is often necessary to test the formaldehyde emission of decorative boards.

[0003] The "device for detecting formaldehyde emission of artificial boards" disclosed in its application number "202220119375.X" "comprises a detection box, a detection mechanism, the detection mechanism includes two threaded rods, the two threaded rods are rotatably connected between the top wall and the inner bottom wall of the detection box, the outer surface of each threaded rod is threadedly connected to a threaded block, and a clamping mechanism, the clamping mechanism includes two clamping plates, each clamping plate is movably embedded in the detection box, the box door improves the sealing performance of the detection box, and the detection work inside the detection box can be monitored at any time through the transparent observation window. The two clamping plates in the clamping mechanism can clamp the boards to be tested, and the two clamping plates are movably connected to the bottom wall of the detection box, which is convenient for testing boards of different thicknesses. When the threaded rod in the detection mechanism rotates, it will drive the threaded block and the mounting plate to rise and fall, thereby driving the detector to move up and down inside the detection box, thereby improving the comprehensiveness of the detection of the boards.

[0004] However, the above method still has the following defects: formaldehyde can be detected using a detection box, but the volatilization of formaldehyde is affected by temperature. When the temperature is low, the volatilization rate of formaldehyde will be reduced, resulting in a decrease in the detection speed. When the board is taken out after the test, formaldehyde is likely to overflow, which will endanger human health. Utility Model Content
