摘要:
The present invention provides a brominated flame retardant determining method that determines whether or not a brominated flame retardant is contained in a determination target object by emitting light to the determination target object composed of resin, receiving reflected light from the determination target object emitted with the light, calculating an absorption spectrum of the determination target object based on the reflected light, and determining whether or not a brominated flame retardant is contained in the determination target object in the absorption spectrum, based on an absorption spectrum in at least one of wavelength bands including a wavelength band of 1.42 µm or more and 1.44 µm or less, a wavelength band of 1.45 µm or more and 1.47 µm or less, a wavelength band of 1.66 µm or more and 1.68 µm or less, a wavelength band of 1.72 µm or more and 1.74 µm or less, a wavelength band of 1.92 µm or more and 1.94 µm or less, a wavelength band of 2.11 µm or more and 2.12 µm or less, a wavelength band of 2.17 µm or more and 2.20 µm or less, and a wavelength band of 2.31 µm or more and 2.34 µm or less.
摘要:
A separation apparatus according to the present invention includes: a conveyor (1) that conveys a group of pieces (2); a material distinguishing unit (3) that distinguishes between first pieces (2A) and second pieces (2B) that are placed on the conveyor(1), according to material; a blower (6) that generates airflow (9) supplied from a middle of the conveyor (1) toward a conveying end (4) along a conveying surface; a first separation unit (5A) that blows off the first pieces (2A) thrown forward from the conveying end (4), based on a differentiation result obtained by the material distinguishing unit (3); a second separation unit (5B) that blows off the second pieces (2B) toward a different place; and a current plate (7) provided below the group of pieces (2) thrown forward and protruding from the conveyor (1).
摘要:
A sorting member with an optimized surface shape is adopted to pressurize a mixture heated on the sorting member to allow a melted resin mixed in the mixture to adhere to the sorting member to sort the resin from an unmelted resin. Thus, resin materials are sorted and recovered from unwanted home electric appliances and the like at a high purity.
摘要:
A crushed piece made of a predetermined material is accurately recovered from crushed pieces. A separation method is provided which extracts a target 1 from a separation subject (101) in which the target (1) to extract and a non-target (2) not to extract are mixed, and includes: distinguishing the target (1) from the non-target (2); obtaining positional information of the target (1) distinguished; attaching a liquid to the target (1) based on the positional information; and extracting the target (1) from the separation subject (101) by bringing a catch member (140) into contact with the separation subject (101) such that viscosity of the liquid causes the target (1) to adhere to the catch member.
摘要:
In a method of separating pieces of a specific constituent substance from a mixture by blowing the pieces across a free-fall position of the mixture by pulse air shot out of a pulse air nozzle, there is a problem that a less amount of the pieces is recovered. A separation method of separating first targets (2) and second targets (7) from a separation subject (101), including: conveying the separation subject (101); distinguishing the first targets (2); obtaining positional information of the first targets (2); dropping the separation subject (101) from an end of a conveyance path; striking a pulsing first airflow (F1) on each of the first targets (2) that is dropping, so as to change a drop path of the first target (2); and striking a second airflow (F2) on the first target (2) which is blown up to or above a predetermined height, so as to change the drop path of the first target (2).
