Definitions
- the present invention relates to a method for the automatic identification of objects or materials, for example plastics.
- Identification means the extraction of information concerning the material or object, cf. GB-A-2 119 509
- This method is particularly applicable to the sorting and recycling of materials from used objects.
- Processes are known for the automatic identification of objects or materials consisting in including in these objects or materials low concentrations of substances having specific luminescence properties, irradiating them with the aid of a broad spectrum light beam. frequency, to perform a spectrophotometric analysis of the response of the substances included in the material and to identify them according to these responses, cf. FR-A-2 901 160 .
- this method is inherently limited in the ability to encode information about the material because of the uniqueness of the type of excitation. It may be useful to code several types of information concerning a material, for example its composition, its recycling path, its manufacturer. It is also limited in the case of strongly colored or black materials, which are relatively frequent. The coloration is due to the presence within the material of colored pigments, in particular carbon black, in variable proportions. Carbon black is used as a radiation protector, mainly UV, in outdoor applications or as a stabilizing and reinforcing agent. Its action consists mainly in absorbing the radiation received by the material that can lead to degradation of the polymer chains.
- the invention therefore more particularly aims to solve this problem with a method for identifying different materials regardless of their color with very low concentrations of markers.
- this method comprises the steps according to claim 1.
- the method involves subjecting a material or object to a combination of different excitation vectors and no longer just to a light excitation.
- the excitation vectors can be applied simultaneously or in sequence.
- the excitations to which matter is subjected cause one or more responses. These answers are compared with the table of correspondence between expected answers and information on the subject, which allows for example to identify this subject. If no answer is obtained, or if the answer obtained is not in the correspondence table, it will not be possible to assign information about the subject.
- spontaneous emission of a selected substance in the absence of an excitation vector for example in the form of spontaneous emission of electromagnetic radiation or of particles, neutral or charged, in particular in the case of the radioactivity, or emission of molecules, including odoriferous.
- the detection step it is possible, in the detection step, to take into account the emission of the material under the effect of the excitation vectors, in particular to correct the responses obtained, for example to subtract the background noise.
- Europium-doped Yttrium vanadate excited between 230 and 390 nm that is to say in the near UV, used alone or in combination with other markers, provides a response centered on 610-620 nm exploitable in the materials. black or strongly colored.
- a dark or strongly colored material is excited in the near UV, a relatively large background noise is observed which requires signal processing, for example to form a baseline, so as to extract and quantify the responses.
- Europium-doped Yttrium vanadate is used in combination with another marker, one of them can be used as calibration, then one works in differential.
- the method makes it possible to collect one or more information concerning a substance or an object, for example a chemical property, in particular its chemical composition and thus to identify the substance under examination or its quality (type, grade).
- the information may also concern the manufacture of the material or the object, for example the identity of its manufacturer, its place or date of manufacture ... We thus go from the simple identification of a subject or an object to its authentication, ie to be able to distinguish an authentic object from an unauthorized copy, for example in the fight against counterfeiting .
- the process is applicable to all types of materials, especially black or highly colored materials, which absorb a wide range of radiation.
- the identification data may comprise the combination of selected markers, the wavelengths of the characteristic lines, their intensity, the duration of a possible fluorescence ...
- the identification data may comprise the combination of selected markers, the wavelengths of the characteristic lines, their intensity, the duration of a possible fluorescence ...
- the identification code may result from a combination of markers and may consist of a binary number whose binary digits each correspond to the presence or absence of a marker.
- the combination of several excitation vectors and markers can make it possible to obtain several pieces of information of different natures on a material, for example the authentication of one or more actors in the life cycle of a material or material.
- an object manufactured, distributor, owner ...
- the material incorporated in the object has been previously marked according to one or more actors involved in the life cycle of a material or an object and not only of its composition.
- the method is applicable to the identification of any type of material, especially materials of any color, more or less dark; it is particularly applicable to the identification of colored or black materials.
- the figure 1 represents the fluorescence intensity curves of three unmarked plastic compounds, Acrylonitrile Butadiene Styrene (ABS, Curve 1), Polypropylene (PP, Curve 2) and Pigmented Polypropylene Black (Curve 3), ABS and PP being two commonly used materials.
- the illumination is produced by means of a UV-TOP light emitting diode (LED) operating at about 330 nm, i.e., in the near UV, with a nominal output power of 1 mW and the spectra are obtained with FluoroMax ® fluorescence spectrometer.
- LED light emitting diode
- the figure 2 illustrates the results obtained with a Xenon arc lamp and a FluoroMax ® fluorescence spectrometer, in the case of black polypropylene marked with the H marker, at two different concentrations, 200 ppm (curve 1) and 100 ppm (curves 2 and 3 ). It is found that the two characteristic peaks of the H marker clearly stand out from the background noise at 614 and 618 nm, thus allowing its identification and thereby the identification of the material in which it is included, even when it is black.
