Description

200815120 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a method for recovering metal from a fine component from a component, such components

The layer, the at least one full surface or structured metal coating has at least one layer of magnetic or magnetizable material. [Prior Art] For example, the method of the present invention is suitable for self-conducting conductive strips on a printed circuit board, RFID antennas, sets, flat cables, forwarding Is antennas or other antenna structures, wafer card seat heaters, foil conductors, Conductive tapes in solar cells or LCD/% water are not recovered from any form of electrolytically coated products. The method of the present invention is also suitable for retrofitting metals from decorative or functional surfaces, for example, for shielding electromagnetic radiation, for use in, for transmission, or as a packaged product. For example, in order for an RFID transponder comprising at least one RFIE antenna and at least one wafer to be used in a wide range, the manufacturing cost must be as low as possible. For example, in this case the ruler!) transponder can replace the conventional bar code on today's consumer goods. If you want to replace the bar code with an RFID transponder, you need a very large RFID transponder. When dealing with consumer goods marked with RFID transponders ^ RFID transponders also form a waste portion. In addition, this means that a large amount of waste containing metal (e.g., copper or silver) is recovered only under extremely difficult conditions by the prior method. A method for recovering rfid transponders is known, for example, from WO-A 02/39357. In the method disclosed herein, the distributor of a consumer product having an RFID transponder 123413.doc 200815120 is targeted to separate and collect the RFID transponder from the retail item when the item is sold. The collected RFID is then forwarded, fixed to new consumer items, and new data is written. However, the disadvantage of this method is the high cost involved in removing the RFID transponder. When you buy items on a daily basis, you want to! This is especially the case when ^10 repeaters are used for marking. WO-A 2006/031824 also discloses a method for reusing an RFIE transmitter. In the methods disclosed herein, the transponders are applied, for example, to a container in which recyclable materials can be collected. The wireless repeater is removed from the container in accordance with the method disclosed in WO-A 2006/03 1 824, and then classified and mechanized for re-use. The method described herein is also not suitable for tagging consumer items with such wireless repeaters. SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for classifying and/or recovering metals of various components at low cost, wherein the components comprise at least one full surface or structured metal coating on the support. Floor. The object is achieved by a method of recovering metal from a component comprising at least one full surface or structured metal coating on a support, the at least one full surface or structured metal coating having At least one layer of magnetic or magnetizable material, wherein the method comprises the steps of: U) pulverizing the components, (8) separating the various materials from which the assembly is made, and removing portions containing the magnetic or magnetizable material. The material from which the assembly is made can be separated from each other by pulverizing the assembly 'at a very low cost. In this case, the pulverization of the electronic component can be carried out by any means known to those skilled in the art for pulverizing the component. For example, the device used for pulverizing is a crusher or a grinder. For example, 'combined crusher H shredder, cone crusher or roller press'. In the jaw crusher or the _ crusher, the crushing space caps and the smashed items are periodically opened and closed. Thereby, pressure is applied to the article to be pulverized to cause it to rupture. In the light cylinder crusher, the items to be pulverized are fed between the reverse rotation rollers through the climbing. These cylinders can be equipped with cams or needles to improve entry conditions. The crusher is generally used to achieve coarse key comminution. For example, a suitable grinder that can be used for pulverization is a roll grinder, a grinder with loose grinding, or an impact grinder. A barrel mill represents a comminution machine in which stress is applied between two surfaces that are heavy and rolling. The 'turning body' used may be a grinding path in which the spherical or roller-shaped β-rolling body is rotated, and is generally designed to be tapered or wedge-shaped. A grinder having a loose abrasive body refers to a pulverizing machine in which the grinding container is partially filled with a freely movable abrasive body. For example, the abrasive bodies can be designed to be spherical or cylindrical. Stone can also be used as an abrasive body. In general, a spherical abrasive body is used. In this case, make the machine. . In the impact mill, the article to be comminuted is given a high speed so that the mouth of the object impacts the surface at a horse speed. For example, a solid or rotating blade, cam or pin is used as the surface. In addition, it is possible to cause the particles to impact other particles in the grinding space. For example, a rotor impact mill in which a necessary speed is generated by means of a rotary rotor or a jet impact mill in which a gas is transmitted at a south speed is used as an impact mill. Unlike a crusher, a much smaller particle size can be achieved using a grinder. For example, using an impact mill, the item to be pulverized can be pulverized into 1 ^ granules.

For example, the removal of particles containing magnetic or magnetizable materials is performed using a magnet. The advantage of separating the magnetic or magnetizable material by means of a magnet is that the particles containing the magnetic or magnetizable material can be substantially completely removed even in the case of particles of different particle sizes and thus different masses. As an alternative, it is also possible to detect magnetic and magnetizable materials and then classify them after comminution using methods known to those skilled in the art. For example, the classification is then performed using any classification method known to those skilled in the art. For example, the removal of other materials that can be made into a component using a portion of a magnetic or magnetizable material that can be classified by a knife can be performed, for example, manually or using a suitable separation device, as is known in the art. The material separation device is, for example, a sieve. In such cases, the separation is based on the different qualities of the particles. For example, particles are entrained by a gas stream in a wind screen. The particles fall due to the force of gravity acting on them. In this case, the private moon is formed by the mass of the particles.

Different path curves. The particles of different qualities are then transported by airflow at different distances. The emperor can then be separated based on the length of flight of the particles in the gas stream. In addition, countercurrent gravity screening is also possible. In this case, the flow is reversed by gravity at a predetermined rate. The m-rate is smaller than the gas velocity. 1234I3.doc 200815120 is lifted by the hole machine. Particles having a falling rate greater than the gas velocity are deposited in the direction of gravity. Separation is carried out in a centrifugal force field in a spiral wind screen. For this purpose, the gas is inhaled inwardly by means of an adjustable rotary deflector impeller. The first force and resistance above the centrifugal force act on the particles dispersed in the gas stream. If the radial component of the airflow is greater than the rate of fall in the centrifugal force field, then the internal extraction is performed. Thereby particles having a lower mass are removed. The external collection has large mass particles. In general, at least one layer of the layer containing the magnetic or magnetizable material is fully == the structured coating comprises at least another material having a good electrical conductivity =' to obtain good electrical conductivity of the at least one coating layer. The material having good electrical properties is preferably copper, silver, gold, tin, palladium or ingot. Since many materials with good electrical conductivity (such as steel, silver, full, tin, sharp or infinite) are not magnetic or non-magnetizable, the magnet removes the $4 material from the scorpion. "In order to achieve a substantially complete removal of the metal used for the group... II:: metal coating, the layers of the two electrically conductive materials containing the magnetic or magnetizable material adhere to each other so as not to be comminuted = have = separation. After the layer containing the magnetic or magnetizable material: the right layer of the conductive material is bonded, so even if the pulverization contains a good conductivity (four) single classification. Particles. In this way, it is possible to carry out the simple connection of the components To the item of the time, the item to be recycled 123413.doc 200815120 is smashed in the v (a) with the 楣 i iK jr^ 7 .

In this case, the electronic item is placed on the consumer item or its seal pen... the tablet is placed directly on the consumer item ιΓΓ (for example, the standard iron) For example, these rfid body wafers can be used as Jg antennas. They have been used as substitutes for today's conventional barcodes. For example, the ancient RFID antenna memory crystals m 丨便仔 a fee thinks to buy shellfish All goods may

When you know the store's checkout area, you can use the laser scanner again. You don't have to use it in the store... In order to realize this system, the department store must be narrow and must have a moving antenna memory chip. / There are a very large number of such RFID antenna memory chips. For example, 'all product features must be stored on the RFID memory chip for retail items with memory chips. The product characteristics are, for example, the price of the item to be sold, the manufacturer, the date of manufacture, the expiration date, the safety statement as appropriate, the logistics information, etc. In the preferred embodiment, the material and/or component of the item to be recycled is recycled. Materials and/or at least one layer of full surface or structured metal coating: and materials that may be contained in other components are also stored on the component, preferably stored in an RFm antenna connected to the sorted, separated or recycled item. In the wafer, for example, when the materials used are also stored on the assembly, they may be pre-classified before they are broken and the items to be recycled. For example, in the case of a material to be recycled, in the case of a plastic article to be recycled, this makes it possible to separate the plastic article in a substantially pure manner depending on the type. For example, #摩皆由123413.doc - 11 - 200815120 In the case of sieving classification, 'due to the fact that the density of plastic products is generally only slightly different', it is only possible under high difficulty. By pre-classifying the characteristics of the products stored on the components, it is possible to smash the items to be recycled and The components are carried out before and after. However, it is preferred to carry out pre-classification before comminution, because the properties of the products stored on the soil and on the parts are subsequently known, and then the materials of the individual parts can be known. Especially when at least - When the material of the full surface or structured metal coating of the layer has a good conductivity: copper, silver, gold, tin, palladium or the like, the method of the invention makes it possible to remove the material with good electrical conductivity in a direct manner. It is especially convenient when the material with good electrical conductivity only constitutes a small part of the item to be recycled. After removing the part containing the magnetic or magnetizable material, it is possible For example, a material having good electrical conductivity is recovered by a smelting method. For example, using a material having good electrical conductivity recovered in this manner, it is again possible to manufacture at least one full surface or structured metal coating on a support. The present invention further relates to an electronic component using the method for recovering metal, the electronic component comprising at least one conductive strip and at least one memory chip on which product information about the electronic component can be stored According to the invention, the at least one electrically conductive strip is composed of at least two layers, at least one of which contains a magnetic or magnetizable material. The slave, the at least one conductive strip and the at least one memory chip are disposed in the branch. On the floor, for example, a rigid or pullable support is suitable for use as a support. The support is preferably non-conductive. This means that the resistivity is greater than 1 〇 9 ohms x cm. For example, suitable supports are reinforced or non-123413.doc -12-200815120 reinforced polymers such as those conventionally used in printed circuit boards. For example, suitable polymers are epoxy resins or modified epoxy resins, such as difunctional or polyfunctional bisphenol A or bisphenol F resins, epoxy-varnish phenolic resins, brominated epoxy resins, aromatic poly Amidoxime-reinforced or glass-reinforced or paper-reinforced epoxy resin (eg FR4), glass fiber reinforced plastic, liquid crystal polymer (LCP), polyphenylene sulfide (PPS), polyfurfural (POM), Polyaryletheretherketone (PAEK), polyetheretherketone (PEEK), polydecylamine (PA), polycarbonate (PC), polybutylene terephthalate (PBT), polyethylene terephthalate Ester • (PET), polyimine (PI), polyimide resin, cyanate ester, bismaleimide-triterpene resin, nylon, ethylene resin, polystyrene Polyester resin, polyamide, polyaniline, phenolic resin, polypyrrole, polyethylene naphthalate (PEN), polymethyl methacrylate (PMMA), polyethylene dioxythiophene, phenolic resin coating Aromatic Polyamide Paper, Polytetrafluoroethylene (PTFE), Triazide Tree, Polyoxin, Shushu, Dip Polyphenyl Ether (APPE), Polyether Amine (PEI), polyphenylene ether (PPO), polypropylene (PP), polyethylene (PE), polyfluorene (PSU), polyethersulfone (PES), polyarylamine (PAA), polyvinyl chloride (PVC) ), polystyrene (PS), acrylonitrile-butadiene-styrene (ABS), acrylonitrile-styrene acrylate (ASA), styrene-acrylic acid, acrylonitrile (S AN), and both of the above polymers Mixtures (blends) of two or more, which may exist in various forms.
