Abstract

The invention discloses a detection device for VOC substances in toy paint, and belongs to the technical field of VOC substance detection, the detection device comprises a base plate, a gas storage tank fixedly arranged at the top of the base plate, and a sucking pump fixedly arranged at the top of the base plate. According to the toy paint spraying device, the interior of the rectangular cylinder is vacuumized through the sucking pump, then clean and pollution-free gas is conveyed into the rectangular cylinder, and then the toy paint in the containing container is heated through the heating block, so that VOC substances in the paint are released conveniently; the toy paint in the container is weighed by using the weighing sensor, so that the accurate weight of the release amount of volatile harmful gases containing formaldehyde, VOC and the like volatilized from the toy paint can be accurately measured, and whether the components containing the volatile harmful gases containing formaldehyde, VOC and the like in a detected object exceed the standard or not can be accurately detected; and the accuracty is higher than that of hte current detection method in addition, the detection device has the advantages of being simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of VOC substance detection, and more specifically relates to a detection device for VOC substances in toy paint. Background technique [0002] With the gradual deepening of people's concept of environmental protection, the environmental indicators of children's toys have been improved again, especially the GB 24613-2009 (national standard) implemented on October 1, 2010, which eliminates heavy metals that are harmful to the human body and the environment in children's toy coatings. In addition to the requirements for solubility and phthalate content, it is also stipulated that the content of volatile compounds (VOC) with a boiling point lower than or equal to 250°C is ≤720g / L, the content of benzene is ≤0.3%, and the content of toluene, ethylbenzene and xylene The sum of the content ≤ 30%. VOC substances refer to the general term of volatile organic compounds whose melting point is lower than room temperatu...
