Technical Field

[0001] The utility model relates to the technical field of VOC content detection, in particular to a volatile organic compound detection device for artificial boards. Background Art

[0002] The presence of VOCs (volatile organic compounds) in wood-based panels is a significant concern. VOCs are organic compounds that evaporate easily at room temperature, including formaldehyde, benzene, toluene, and xylene. These harmful substances may be released during the production of wood-based panels due to the use of chemicals such as adhesives.

[0011] (3) Beneficial effects

[0012] 1. Align the bottom of the shell with the installation hole or slot of the artificial board, press it hard, and the annular suction cup at the bottom of the shell will make the shell tightly adsorbed on the surface of the artificial board, slide the top rod downward, so that the magnet at the bottom of the top rod contacts the metal sheet at the top of the sealing plug, and then slide the top rod upward. The top rod will absorb and pull up the sealing plug through the magnet to open the opening of the sampling tube, and start the vacuum pump to extract the air inside the shell and the sampling tube to prevent the original air from affecting the detection accuracy. After standing for a period of time, the volatile substances of the artificial board will enter the shell and the sampling tube. Inside the tube, slide the push rod downward with force, and the push rod pushes the sealing plug downward into the inside of the sampling tube.
