Automotive interior material VOC (volatile organic compounds) detection device

Abstract

The invention discloses an automotive interior material VOC (volatile organic compounds) detection device which comprises an aging tank, a supporting trench, a sampling bag, a pair of sampling pipes,a nitrogen blanketing valve and a vacuum-pumping pipe. An opening of the supporting trench faces the top of the aging tank, the sampling bag wraps the outer side of the supporting trench, a pair of first rods and a pair of second rods penetrate one side wall of the sampling bag and are arranged on lifting components in an outward extending manner, one end of a cylindrical injection port is connected onto one side wall of the sampling bag, a pair of first elastic frames are arranged at the joint of a bottom surface and a side surface and the joint of a top surface and the side surface, two endsof a plurality of multi-connecting rods are hinged onto the first elastic frames, the sampling pipes are communicated to cavities of the first rods, and the nitrogen blanketing valve and the vacuum-pumping pipe are communicated to cavities of the second rods. Uniform heating of automotive interior materials in the VOC detection process can be ensured by the sampling bag suspended in the aging tank, and VOC diffusion effects are closer to true situations, so that VOC detection results are more accurate.

Description

technical field [0001] The invention relates to the technical field of VOC detection, in particular to a VOC detection device for automotive interior materials. Background technique [0002] The volatile organic compounds emitted by cars are very harmful to people. When the VOC in the car reaches a certain concentration, people will feel headache, nausea, etc. in a short time, and convulsions will occur in severe cases, and will damage the human liver, kidneys, Brain and nervous system. VOC is the English abbreviation of volatile organic compounds (volatile organic compounds). VOC in the general sense is command volatile organic compounds; but the definition in the sense of environmental protection refers to a type of active volatile organic compounds, that is, the type of volatile organic compounds that will cause harm. [0003] The conventional bag-type VOC detection device is actually a VOC sampling bag used for VOC detection. The VOC sampling bag is made of polyvinyl f...

Problems solved by technology

During this process, the sampling bag is often placed directly on the metal frame of the environmental aging chamber, and the automotive interior materials or parts press some of the sampling bags, which will lead to uneven heating of the automotive interior materials or parts and partial aging. The release of VOC is hindered, resulting in inaccurate test results; in addition, the VOC sampling bag used in the conventional bag-type VOC test is generally a rectangular polyvinyl fluoride (PVF) film plastic bag. When the inflation is not sufficient, the shape is difficult to control. Part of the bag above the automotive interior materials or parts may even cover the surface of the car interior materials or parts, which will also cause uneven heating of the automotive interior materials or parts and hinder the release of some VOCs, resulting in inaccurate test results ; and when the automotive interior materials or parts that are configured with glue or adhesive tape are put into the above-mentioned VOC sampling bag, the above-mentioned glue or adhesive tape will also easily adhere to the VOC sampling bag, so it will affect the secondary function of the VOC sampling bag. Used for one time, causing unnecessary economic losses to the enterprise
