Embodiment approach 1

[0034] figure 1 It is a schematic diagram of the specific brominated flame retardant judging device 1 according to Embodiment 1.

[0035] Resin 2 which is an object of judgment is a resin such as polypropylene having a methyl group, in which it is unclear whether or not a specific brominated flame retardant is contained. use figure 1 The configuration of the specific brominated flame retardant determination device 1 for detecting a specific brominated flame retardant from the resin 2 will be described.

[0036] The specific brominated flame retardant judging device 1 includes at least an infrared detection unit 8 and an arithmetic processing unit 10 . The specific brominated flame retardant determination device 1 may further include a digital data conversion device 9 .

[0037] The infrared detection unit 8 has the functions of the irradiation unit and the light receiving unit according to the present disclosure, and has the function of irradiating infrared rays to the re...

Abstract

A resin is irradiated with an infrared ray, and a reflected ray from the resin irradiated with the infrared ray is received. In a reflection or absorption spectrum obtained by the reflected ray, a difference of a reflection intensity in a spectrum between a first wave number band of 1340 cm<-1> to 1350 cm<-1>, inclusive, and a second wave number band of 1300 cm<-1> to 1340 cm<-1>, inclusive, is calculated. It is determined whether or not a specific bromine-based flame retardant is contained in the resin, by using the calculated difference of reflection intensity in the spectrum.

Description

technical field [0001] The present disclosure relates to a specific brominated flame retardant judging method and device for determining whether a resin contains a specific brominated flame retardant. Background technique [0002] Global-scale environmental problems such as global warming and resource depletion occur due to mass consumption and mass waste-type economic activities. [0003] In this situation, in order to build a resource recycling society, the Home Appliances Recycling Law was enacted in Japan in April 2013. According to the Home Appliance Recycling Law, recycling of used home appliances (air conditioners, TVs, refrigerators, freezers, washing machines, clothes dryers, etc.) is compulsory. [0004] As a result, used home appliances are crushed at the home appliance recycling factory, and then sorted and collected for each material using magnetism, wind power, vibration, etc., and are reused as recycled materials. [0005] In addition, in the "Restriction of...
