Formaldehyde detection equipment and detection method for indoor decoration plates

The invention belongs to the technical field of formaldehyde detection of indoor decoration plates, and relates to a formaldehyde detection method for indoor decoration plates, which comprises the following steps: 1, forming a gas phase and a liquid phase from formaldehyde of a to-be-detected plate; 2, measuring the content of formaldehyde in the gas phase; 3, measuring the content of formaldehyde in the liquid phase; 4, adding the formaldehyde content obtained in the step 2 and the formaldehyde content obtained in the step 3 to obtain the total formaldehyde content; 5, introducing the detected formaldehyde-containing gas into a formaldehyde dissolving device to form a formaldehyde solution; according to the method, the formaldehyde in the plate can be more thoroughly extracted by adopting a liquid phase and gas phase combined mode, so that the measurement result is more accurate; meanwhile, separation of formaldehyde in a liquid phase is combined with an image processing technology and a microwave signal cha
