Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method and an apparatus for identifying used resin.
[0002]
[Prior art]
In recent years, interest in global environmental conservation has increased, and effective use of resources and reduction of waste have been favored. In addition, from these viewpoints, for example, used industrial products as represented by the Specific Home Appliance Recycling Law, etc. Has been shouting highly at recycling. Under such circumstances, for large industrial products represented by, for example, passenger cars or home appliances, after collecting and dismantling the industrial products, separate the collected and dismantled products into various constituent materials and recycle them. However, most of the constituent materials of such industrial products are subjected to landfill, incineration or solid fuel processing, even if the resin is recycled. Even in this case, the recycled resin is generally used as a very low-grade recycled resin such as railroad sleepers and piles. This means that the means for recycling the resin used in various industrial products is based on the type of resin itself, the type or amount of additives contained in the resin, or the state of the resin (for example, the state of coating on the resin surface). In many cases, and it is difficult to recycle as a resin of uniform quality.
[0003]
For example, when the used industrial product is a used TV and the resin is collected / reused from the used TV, the casing material of the used TV is usually made of resin. The resin, additives (for example, a flame retardant, etc.) in the resin, or the state of coating, etc., are completely different depending on the type of the used television. Furthermore, even if the used TV casings are the same model, the resin coating state (for example, the presence or absence of coating) differs depending on the region, such as the front part and the rear cover part. The resin identification process becomes complicated, and an identification method that can easily perform this process has been desired.
[0004]
By the way, a fire retardant, such as decabromodiphenyl oxide (also referred to as decabro), which is said to possibly generate dioxin when incinerated, is disliked, and a housing resin not using such a flame retardant (for example, decabro as a flame retardant). In recent years, non-deca high-impact polystyrene resins that do not contain styrene are commonly used, but many televisions produced in the past contain decabro, so even if the same type of resin is used, additives (for example, flame retardants) In some cases, different processing needs to be performed depending on the type of the data. For this reason, there has been a demand for a method capable of industrially performing the resin identification process and the separation process.
[0005]
Under the above circumstances, a resin identification device using FT-IR (Fourier transform infrared spectrophotometer) has been proposed and studied (Patent Document 1), but the resin surface is black, If painted, the accuracy of identification is extremely reduced, and the equipment is large and / or expensive, requires pretreatment (eg, preparation of sample pieces or polishing of sample surface), or Due to various technical problems such as the time required for measurement and the like, a highly accurate and small resin identification device has been desired.
[0006]
Furthermore, even if the industrial products are of the same model, if the colors of the industrial products are different, the paints and the like contained in the industrial products are different, and as a result, the processing means of the used industrial products is different, and furthermore, Or affect the color development of industrial products after recycling. For example, if the resin of a red used industrial product is recycled as an industrial raw material, the recycled resin can be used for recycling to a black industrial product, but it can be recycled to a white industrial product. It is difficult to use from the viewpoint of color development.If the resin of a black used industrial product is recycled as an industrial raw material, the recycled resin is used for recycling to ivory industrial products It is difficult from the viewpoint of coloring.
