Problems solved by technology

[0002] At present, the detection methods of formaldehyde emission in finished furniture, wood-based panels and building materials include desiccator method, extraction method, environmental test chamber method and gas analysis method. The desiccator method is to cut 10 pieces of 150mm×50mm samples from the sample and place 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 perform destructive testing on the samples. At present, the most scientific and effective testing method is the environmental testing chamber method. None of the methods can achieve the purpose of online and rapid detection, and some methods are destructive to samples, causing great economic losses

Embodiment 1

[0011] A rapid detection device for formaldehyde in wood-based panels and furniture products consisting of collectors, filters, suction pumps, and detectors. The collector 1 is set and fixed behind the wood-based panels or furniture, and the suction pump 2 is started to extract the collector. The air in the air reaches a vacuum degree of 4, and then the filter valve 3 is opened to allow the air from the external environment to enter the collector through the filter. When the pressure of the external environment reaches equilibrium, the formaldehyde rapid detector 5 is started to collect the air in the collector through the air outlet. The air sample is used to detect the formaldehyde content in the air, so as to determine the environmental safety performance of the sample. The device can carry itself and directly adsorb to the surface of the sample to collect volatilized formaldehyde to realize online detection. Collectors, filters, suction pumps and detectors can be selected....

Abstract

The invention discloses a quick formaldehyde detection device for artificial boards and furniture products. The formaldehyde detection device is characterized by comprising a collector, an air suctionpump and a detector, a vacuum meter (4) and a filter valve (3) communicated with air are arranged on the collector (1), a suction inlet of the air suction pump (2) is communicated with the collector(1), and an outlet of the air suction pump (2) is connected to a formaldehyde quick detector (5). The invention discloses a portable detection device for quickly detecting the volatilization amount ofharmful volatile substances of formaldehyde in finished furniture and building materials. The device has the functions that the developed device has an adsorption type self-breathing function, volatile formaldehyde in artificial boards and furniture products is collected, and the environmental protection quality safety of the products is determined in combination with a formaldehyde quick detector.

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 environmental te...
