Rapid nondestructive testing device and nondestructive testing method for formaldehyde emission

Abstract

The invention discloses a rapid nondestructive testing device and a nondestructive testing method for formaldehyde emission, belongs to the technical field of formaldehyde detection, and aims to solve the problems that after the formaldehyde content in air reaches a certain amount, formaldehyde in furniture is not released any more, air circulation is needed, detection is troublesome, and the internal sealing performance is difficult to guarantee. In addition, the content of the formaldehyde needs to be measured after the formaldehyde is sampled, and the formaldehyde is inconvenient to collect. Teeth on a bevel gear are meshed with tooth grooves in the two sides of the interior of an arc-shaped ring in a reciprocating mode, finally, the arc-shaped ring does up-down reciprocating motion, and when the arc-shaped ring does up-down reciprocating motion, a piston is driven by a movable rod to do up-down motion in a barrel; when the piston moves up and down in the barrel, air between the first shell and the to-be-detected object is conveyed into the collecting funnel, formaldehyde in the air is dissolved into distilled water when entering the collecting funnel, the formaldehyde is rapidly collected, the detected object can be prevented from being damaged, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of formaldehyde detection, in particular to a rapid nondestructive detection device and a nondestructive detection method for formaldehyde release. Background technique [0002] Formaldehyde is an organic chemical substance. It is a colorless and irritating gas. It is irritating to human eyes and nose. Compared with water and ethanol, the concentration of the aqueous solution can reach up to 55%, generally 35%-40%, usually 37%, called formaldehyde water, commonly known as formalin. [0003] At present, furniture and baseboards in the home decoration environment often have formaldehyde exceeding the standard, and the traditional detection method is to sample the furniture and then put it in a constant temperature and humidity convection detection box for detection. The disadvantage of this is that it will cause damage to the furniture. A method of covering the surface of furniture to form an independent spac...

Problems solved by technology

[0005] The object of the present invention is to provide a rapid non-destructive testing device and non-destructive testing method for formaldehyde emission, which solves the problem of a cover on the surface of furniture in the background technology, so that the cover Form an independent space inside and detect the formaldehyde release gas in the space. Although this method can be detected without destroying the furniture, the formaldehyde in the furniture will no longer be released after the formaldehyde content in the air reaches a certain amount. , requires air to circulate, the detection is more troublesome, and its internal sealing is difficult to guarantee. In addition, after the formaldehyde sampling is completed, its content needs to be measured, which is also inconvenient for the collection of formaldehyde
