Artificial board and formaldehyde detection device for furniture products

Abstract

The invention discloses an artificial board and formaldehyde detection device for furniture products, relating to a formaldehyde detection device. The device is characterized by comprising a collector, an aspirator pump and a detector, wherein the collector (1) is equipped with a vacuum gauge (4) and a filter valve (3) which is communicated with air, the suction inlet of the aspirator pump (2) is communicated with the collector (1), and the outlet of the aspirator pump (2) is connected with the fast formaldehyde detector (5). The invention discloses a portable detection device which is used for fast detecting the volatilization volume of harmful formaldehyde volatile substances in finished furniture and building materials, and the functions are as follows: the device has the adsorptive self-respiration function, and can collect formaldehyde volatilized by the artificial board and the furniture products, and combine the fast formaldehyde detector so as to guarantee the environmental friendliness, quality and safety of the products.

Description

technical field [0001] The invention relates to a formaldehyde detection device, in particular to a formaldehyde rapid detection device for wood-based panels and furniture products. Background technique [0002] The current detection methods for formaldehyde release in finished furniture, wood-based panels, and building materials include dryer method, extraction method, environmental test chamber method, and gas analysis method. The dryer method is to cut 10 pieces of 150mm×50mm samples from the sample and put them in the The detection time is up to 24 hours in a desiccator. The extraction method is mainly used for the detection of man-made boards. It is cut into 20mm×20mm slices, and the formaldehyde in the sample is extracted with toluene. The gas analysis method is to intercept a 400 mm×50 mm sample for detection. , the above three methods all carry out destructive testing on the samples. At present, the most scientific and effective testing method is the environmenta...
