As a result, the present inventors have found that the printing layer of the optical disc is separated, and the pedestal = the lack of various kinds of fascination, so that it is painstakingly sought after, and after many experiments and improvements, the present invention was first created. SUMMARY OF THE INVENTION The present invention is invented by the inventors of the present invention, using a method of immersing and immersing a UV-curable adhesive layer to separate the molecular layer structure of the discarded optical recording medium. It refers to a method of separating and polymerizing a polymer layer by heating/dipping/packaging. By using the treatment method of the invention, the polymer layer is first separated, and then the metal film thereon is removed, that is, the recovery process is completed individually, and the separation can be completed with high efficiency with a simple operation and a small cost, and is favorable for subsequent recovery. Therefore, it is characterized by being safe, reliable, low-cost, high-value recyclability, etc., characterized in that the heat-dissolved optical recording medium is used to separate the polymer layer, and the manufacturing method thereof is as follows: (a) Classification: various types of light are used The records are classified according to the type of recycled materials; (b) heating soaking: the classified optical recording medium is placed in a heated immersion environment to separate the non-single-layer substrate structure of the discarded optical recording medium; (C) removing the substrates Adhesive layer: The optical recording female body is placed in the dissociation environment; (d) Recycling: Separate substrate material and 1281882 materials are separately recovered for further reuse. [Method for Carrying out the Invention] The present invention is a process for separating a polymer layer from an optical disk, taking CD-R as an example, and the structure thereof is a polymer layer, a metal reflective layer, and a polycarbonate layer, and the following are feasible steps. One: (a) Classification: Various types of optical recording media are classified according to recycled materials. For example, according to the content of the reflective layer (such as gold, silver, aluminum alloy); (b) heating soak: moisture and high temperature help to destroy the UV-cured adhesive layer, separating the polymer structure of the waste optical recording medium In order to facilitate the subsequent recycling process, the temperature is maintained at 80 ° C for more than 20 min. The optical recording medium can be further processed into two parts, one is a polymer layer, and the other is a metal reflective layer and a polycarbonate layer. This step can be Simultaneous processing of multiple optical recording media for rapid recovery and separation. (c) Separating the metal adhesion layer of the substrate: the optical recording medium is placed in a dissociation environment, i.e., at least one or more optical recording medium substrates having at least one metal film layer structure on the surface are transferred to a subsequent dissociation process. (d) Recycling • The separate substrate material and metal material are separately recovered for further reuse. The above heating and immersing environment is a liquid-containing immersion tank which can generate a heating effect, and the immersion tank can be further combined with increasing the temperature, adding an organic solvent, an acid, a test, a salt, a washing, an ultrasonic, a flowing water or a mechanical disturbance. Shorten the removal time and other methods, and when heated and immersed, it can simultaneously smash 281,882 force filtration, the system will soak the solution in the soaking solution f and remove 'so that higher purity recovery can be obtained. The polymer layer from φ and the organic solvent mentioned in the previous paragraph can be high and miscible with water' or can soften the strength between layers = strong cleaning power, flash fire Μ reduce the intrusion buffer of deuterated solvent on the substrate ^ The addition of a humanized solvent' or a solvent to the disintegration rate of the layered structure may be added to the case where the loosened adhesive is applied back to the substrate or may be reduced by mixing the solvent. '+ such as anti-static additives, etc., after heating and soaking to assist the dissociation of semi-finished products, mechanical force, chemical agents, arcs, and then at least, to; a method of 隹 冤 冤 magnetic waves and ultrasonic waves, completely dissociated in a step-by-step manner Or, firstly, the first wave of 77 - chemical agents, arc, electrochemistry, electromagnetic waves and ultrasonic waves, decomposition and re-distribution, and the heating and soaking gamma dissociation can be one of the multi-channel processes. Wang Mi; for the second Γ - body into the heating soaking environment: way, can be recorded _ batch into the heating soaking environment. Circumventing the production. However, the two-light s recording media is sent to the heating and soaked in the conveyor belt to receive the dissociation '隹 隹 隹 再 再 再 再 再 轮 · · · · · · ' ' ' ' ' ' ' ' ' ' ' ' In the round _ lose $ to add and subtract bubbles in the environment, the item is ordered to receive the heating soaking environment, and the medium is sent away from the heated immersion environment. u (4)' & 1281882: 2 can achieve the purpose of destruction and dissociation, all suitable for this method. In the above, the 2 optical recording media can be ground and scraped due to materials, manufacturing parameters and quality control. The electromagnetic wave can include: wave == learning can include electrolysis and electric waves and arcs, all of which are applicable to the present invention. The stratified or destroyed electric field ΓΠ n s.,, the dry circumference of the week. Moreover, the above examples are taken as an example. However, this technique is also applicable to the dissociation of other _photographing bodies which are fixed by ultraviolet light and printed layers. In fact, although the 4th =: CD is the object of processing, but in the course of manufacturing the optical recording medium = ^ 隹 or in the final inspection process after the manufacturing becomes a defective product, J reaches the water ^ _ inventory class It is also possible to: "No matter what layered structure is present on the substrate layer, it is possible to carry out the recovery of the material of the genus and the genus by the same treatment method as described above." Read-only music CD (CD), CD-ROM, Vide〇_CD, interactive light = (CD-I), audio-visual DVD (DVD_Vide〇), read-only dvd disc (DVD-ROM) 'single recordable—((4)), single write repeat read disc (W0RM), overwriteable DVD disc (DVD-RAM), repeatable read/write disc (CD-RW) 'Magnetic disc player (|1〇), mini disc (MD), repeatable rewritable DVD disc (DVD-RW), because of these types of discs, if there is a printed layer structure, it is suitable for this method.如此 Thus, if the above-mentioned treatment process is used, the metal and substrate materials are recovered only by the simple processing unit 1281882: ΐ::Γ=Γ光, and the purity of the substrate material is recovered, and recycling is made possible. And by = == discarding the optical recording medium to remove the unnecessary thin layer, and recovering the ttrr, which has the advantage of reducing the cost of light, the recovery procedure of the optical recording medium is more rapid and economical, and the retentate is retained. There is a high value of recyclability in the recycling process of recycled materials. The processing method provided by the present invention is applicable to an optical recording medium which is damaged from the manufacturing process, or a defective silk recording medium during the final inspection process after manufacture, or becomes an optical record of the remaining inventory. Carcass, etc., recover the substrate material and recycle it. Since the substrate material with high purity can be recovered, the substrate material can be reused as a substrate for an optical recording medium, or can be used in a wide range of use towels such as a disc package or a personal computer case. And the material used in the ring is: It has extremely high economic benefits, and can effectively avoid the material pollution caused by the optical recording process. The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. According to Tian Xiong, the invention has indeed been available for industrial use. ^There is no known feature of the same invention, and the public is the first. Therefore, the invention can meet the application requirements of the invention patent and patent according to law.
