Nondestructive testing device of formaldehyde emission from furniture product and nondestructive testing method thereof

The invention relates to a nondestructive testing device of formaldehyde emission from furniture product and a nondestructive testing method thereof. The nondestructive testing device comprises an adjustable telescoping bracket, the bracket is externally covered with a PVC film, and seal plates are arranged between two adjacent telescoping bracket feet for compressing the PVC film to form airtight space inside the PVC film. The nondestructive testing method comprising the following steps: (1) the to-be-detected product is arranged in the airtight space formed by the PVC film, the telescoping bracket and the seal plates; (2) an absorption vessel with distilled water is arranged right below the to-be-detected product for 8-12 hours; (3) the absorption vessel is taken out, and acetylacetone spectrophotometry is carried out on the absorption liquid inside the vessel to detect the concentration of formaldehyde. The nondestructive testing device has the advantages of reasonable structure, low manufacture cost and s
