Description
본 발명은 그라비아 인쇄기에 사용되는 실린더의 표면에 피막처리된 구리코팅층을 탈피하여 재사용할 수 있도록 하는 구리코팅층 재활용방법에 관한 것으로서, 더욱 상세하게는 철강재의 실린더 표면에는 니켈코팅층, 구리코팅층, 크롬코팅층의 3단계 도금층이 형성되어 있는바, 이들 중 고가인 구리코팅층을 따로 분리하여 재활용할 수 있도록 하는 인쇄용 실린더의 구리코팅층 재활용방법을 제공하는 것이다.The present invention relates to a copper coating layer recycling method for removing the coated copper coating layer on the surface of the cylinder used in the gravure printing machine for reuse. The three-stage plating layer is formed, it is to provide a copper coating layer recycling method of the printing cylinder to separate and recycle the expensive copper coating layer of these.
일반적으로 그라비아 인쇄기에 사용되는 실린더는, 철강으로 실린더를 주조하고, 이 실린더의 표면에 니켈을 약 5㎛의 두께로 피복하여 니켈코팅층을 형성하고, 이어서 구리코팅층을 형성하게 되는데, 상기 구리코팅층은 약 120㎛이상의 두께로 피복 형성하게된다.In general, a cylinder used in a gravure printing machine, casts a cylinder of steel, the surface of the cylinder is coated with nickel to a thickness of about 5㎛ to form a nickel coating layer, and then to form a copper coating layer, the copper coating layer The coating is formed to a thickness of about 120 μm or more.
이후, 상기 구리코팅층의 외주면에는 크롬을 약 8㎛ 정도로 코팅하여 크롬코팅층을 형성하여, 이 크롬코팅층에 인쇄를 위한 후처리를 하게 되는 것이다.Thereafter, the outer circumferential surface of the copper coating layer to form a chromium coating layer by coating the chromium about 8㎛ to the post-treatment for printing on the chromium coating layer.
상기 인쇄를 위한 후처리는, 크롬코팅층에 감광액을 바르고, 필름원고를 실린더에 권취한 후, 빛쪼임을 실시하여 실린더의 크롬코팅층에 필름원고와 같은 모양의 화선부를 현상한다.In the post-treatment for printing, a photoresist is applied to the chromium coating layer, the film original is wound around the cylinder, and then light is applied to develop a wire portion having a shape such as a film original on the chromium coating layer of the cylinder.
이어서, 상기 화선부를 부식액으로 용해시켜 오목하게 만든다. 이러한 과정을 식각과정이라 칭하는데, 최근에 들어서 이러한 식각공정은 레이저를 이용한 조각으로 대체하고 있는 실정이다.Subsequently, the caustic part is dissolved with a corrosion solution to make it concave. This process is called an etching process, and recently, such an etching process has been replaced by laser engraving.
이와 같이 식각과정을 통해 오목하게 화선부를 형성한 다음, 그 상부에 잉크를 도포하여 상기 화선부에 잉크가 충진되도록 한 다음, 실린더 표면의 잉크를 제거한다. 이후 인쇄 실린더를 회전시켜 인쇄지 위에 화선부를 밀착시켜, 화선부에 충진된 잉크가 인쇄지로 묻어 인쇄하도록 하는 것이다.After forming the concave line portion through the etching process as described above, ink is applied to the upper portion of the wire line by applying ink thereon, and then the ink on the cylinder surface is removed. Thereafter, the printing cylinder is rotated to closely contact the wire line on the printing paper, so that the ink filled in the wire line is buried with the printing paper to print.
이러한 일련의 과정을 통하여 인쇄를 하는 그라비아 인쇄기는, 한번의 연속된 인쇄작업이 완료된 후에는 실린더의 표면에 형성되는 크롬코팅층과 구리코팅층 및 니켈코팅층을 전부 박리시키고, 다시 새롭게 니켈, 구리, 크롬을 코팅하여 새로운 인쇄작업을 하게되는 것이다.The gravure printing machine, which prints through this series of processes, peels off all of the chromium coating layer, copper coating layer and nickel coating layer formed on the surface of the cylinder after one continuous printing operation is completed. The coating will be a new print job.
상기한 바와 같은 인쇄기의 실린더는 인쇄종목이 바뀔때마다 실린더 표면에 코팅된 도금층을 탈피하고, 다시 코팅하은 작업을 반복적으로 하여야 하는 것이다.The cylinder of the printing machine as described above is to peel off the coating layer coated on the surface of the cylinder every time the printing item is changed, and to repeat the coating operation.
따라서, 고가의 구리도금층을 한번 사용한 후에는 버리게 되어 경제적인 손실이 많았다.Therefore, after using the expensive copper plating layer once, it was discarded and there was much economic loss.
그라비아 인쇄기용 실린더의 크기는 그 직경이 약 25cm 이상의 직경과, 1m이상의 길이로 형성된 것이 통상적으로 사용되고 있는 바, 이러한 크기를 가진 실린더 전체를 코팅하는 구리를, 한 번의 사용으로 폐기 처리하는 것은 국가적으로도 손실인 것이다.The size of the cylinder for a gravure printing machine is generally used having a diameter of about 25 cm or more and a length of 1 m or more. Since the copper coating of the entire cylinder having such a size is disposed of in one use, it is national Is also a loss.
본 발명은, 상기한 바와 같은 인쇄기용 실린더의 표면에 코팅된 구리코팅층을 사용 후에는 다시 탈피하여 재사용할 수 있도록 하는 방법을 제공하는 것이다.The present invention is to provide a method for allowing the copper coating layer coated on the surface of the cylinder for printing machine as described above to be peeled back and reused after use.
즉, 니켈코팅층의 위에 120㎛ 이상의 두께로 코팅처리되는 구리코팅층을 실린더로부터 분리시켜 다시 새로운 실린더를 구리코팅 할 때 재활용할 수 있도록 하는 것으로, 상기 실린더의 니켈 도금층에 은을 코팅하여 은코팅층을 형성한 후, 그 위에 구리코팅층을 형성하여, 인쇄사용한 후 실린더의 표면에서 구리코팅층만을 따로 분리하여 재활용하도록 함으로써 상기한 문제점을 해결하고자 한다.That is, the copper coating layer coated with a thickness of 120 μm or more on the nickel coating layer is separated from the cylinder to be recycled when the new cylinder is copper coated, and the silver coating layer is formed by coating silver on the nickel plating layer of the cylinder. After that, by forming a copper coating layer thereon, to solve the above problems by separating and recycling only the copper coating layer from the surface of the cylinder after printing use.
본 발명에 의해 인쇄기의 실린더에 코팅된 구리를 수거하여 재활용함으로써 귀하고 고가인 구리를 낭비하지 않을 수 있어, 국가의 소중한 천연자원의 낭비를 방지할 수 있으며, 기업에서는 고가의 구리를 몇 번이고 재활용하여 제작비용을 절감하는 효과를 얻을 수 있는 것이다.By collecting and recycling the copper coated on the cylinder of the printing machine according to the present invention, it is possible to avoid wasting precious and expensive copper, thereby preventing the waste of precious natural resources in the country, and in the enterprise many times expensive copper is Recycling can reduce the manufacturing cost.
이러한 효과를 얻을 수 있는 본 발명을 이하에서 상세히 설명한다.The present invention to obtain such an effect is described in detail below.
철재의 실린더 표면에 니켈을 5~7㎛의 두께로 피복하여 니켈코팅층을 형성하고, 그 위에 구리를 100~130㎛의 두께로 피복하는 구리코팅층과, 크롬을 8㎛의 두께로 형성한 크롬코팅층을 형성한 통상의 그라비아 인쇄기용 실린더에 있어서, A nickel coating layer is formed by coating nickel on the surface of the steel cylinder with a thickness of 5 to 7 μm, and a copper coating layer covering copper on a thickness of 100 to 130 μm thereon, and a chromium coating layer having chromium on a thickness of 8 μm. In the conventional gravure printing cylinder,
상기 철재의 실린더 표면에 형성된 니켈코팅층이 형성된 실린더를, 필름현상폐수에 45% 정도 침적시킨 상태에서 3분가량 회전시키는 무전해 도금법에 의해, 상기 필름현상폐수 중의 은성분을 상기 니켈코팅층 위에 은코팅층이 형성되도록 하고, 상기 은코팅층 위에 구리코팅층과 크롬도금층을 차례로 코팅 처리하여서 된 것이다.The silver coating layer on the nickel coating layer was deposited on the nickel coating layer by the electroless plating method of rotating the cylinder having the nickel coating layer formed on the surface of the steel cylinder in the state of being deposited about 45% in the film developing waste water for about 3 minutes. This is to be formed, by coating the copper coating layer and the chromium plating layer in turn on the silver coating layer.
이러한 과정으로 은코팅층을 형성한 실린더를 인쇄기에 장착하여 사용한 후에는, 상기 크롬코팅층에 40~60%의 염산용액을 40~50℃의 온도로 30분간 상기 실린더에 분사하여 크롬코팅층을 제거하고, 크롬코팅층이 제거된 실린더의 구리코팅층을 탈피하게 되는 것이다.After mounting the cylinder with the silver coating layer formed in this process on a printing machine, 40 to 60% hydrochloric acid solution was sprayed onto the cylinder at a temperature of 40 to 50 ° C. for 30 minutes to remove the chrome coating layer. The copper coating layer of the cylinder from which the chromium coating layer has been removed is peeled off.
상기 실린더에 염산용액을 분사하여 크롬코팅층을 세척할 때, 실린더를 지속적으로 회전시켜주면, 세척효과는 배가되고, 세척시간도 약 1/2 정도로 단축할 수 있게 된다.When washing the chromium coating layer by spraying the hydrochloric acid solution on the cylinder, by continuously rotating the cylinder, the washing effect is doubled, the washing time can be reduced to about 1/2.
상기 구리코팅층은, 니켈코팅층 상에 코팅형성되어 있어서, 상기 구리코팅층의 일단을 절개하여 벗겨내면 쉽게 구리코팅층만 탈피되는 것이다.The copper coating layer is coated on the nickel coating layer, so that only one copper coating layer is easily peeled off by cutting off one end of the copper coating layer.
이렇게 하여 구리코팅층이 탈피되면, 이들을 모아 공모양의 형태로 취합하고, 이들을 구리괴의 현태로 압축하여 보관한다. 이후에 다른 실린더에 구리코팅층을 형성하는 전해조에 담가 재활용하는 것이다.When the copper coating layer is peeled off in this way, these are collected and collected in a ball shape, and these are compressed and stored in the state of copper ingot. Subsequently, it is immersed in an electrolytic cell that forms a copper coating layer on another cylinder and recycled.
물론, 탈피된 구리조각을 그대로 포대에 담아 전해조에 투입하여도 동일한 효과를 얻을 수 있다.Of course, the same effect can be obtained even if the stripped copper pieces are put in the bag as it is and put into the electrolytic cell.
상기 구리를 실린더에 코팅하는 수단은, 도금을 위한 도금욕조 안에 전해액을 채우고, 상기 탈피된 종이형상의 구리을 모아 압축하여 공의 형상으로 만든 구리괴를 넣고, 상기 실린더를 침적시킨다.The means for coating the copper on the cylinder is filled with an electrolyte solution in a plating bath for plating, the stripped paper-like copper is collected and compressed into a ball-shaped copper ingot, and the cylinder is deposited.
이어서, 구리괴에는 양극을, 실린더에는 음극을 접속시킨 후 전원을 공급하면 전기분해에 의해 실린더의 표면에 구리코팅층이 형성되는 것이다.Subsequently, when the anode is connected to the copper ingot and the cathode is connected to the cylinder, and power is supplied, a copper coating layer is formed on the surface of the cylinder by electrolysis.
여기에서 상기한 실린더의 구리코팅층을 박피하는 수단을 설명한다.Here, the means for peeling the copper coating layer of the cylinder will be described.
상기 실린더를 회전수단이 구비된 척에 고정하고, 실린더의 양측면에 바이트를 이용하여 코팅층을 일차적으로 깍아 내고, 실린더의 표면에 약 120㎛의 깊이로 절단날로 길이방향으로 절결하며, 상기 절결된 구리코팅층의 일단을 파지하고, 상기 실린더를 저속으로 회전시킴과 동시에, 상기 구리코팅층을 파지하고 있는 파지구를 일측으로 서서히 이동시키면서 상기 실린더에 코팅된 구리코팅층을 박피하게 되는 것이다.Fixing the cylinder to the chuck equipped with the rotating means, by first cutting the coating layer using a bite on both sides of the cylinder, longitudinally cut into a cutting blade to a depth of about 120㎛ on the surface of the cylinder, the cut copper One end of the coating layer is held, and the cylinder is rotated at a low speed, and the copper coating layer coated on the cylinder is peeled while gradually moving the gripper holding the copper coating layer to one side.
이러한 간단한 기계적인 도구를 이용함으로써 손쉽고, 간단하게 실린더의 구리코팅층을 박피할 수 있게 된다.By using this simple mechanical tool, the copper coating layer of the cylinder can be easily and simply peeled off.
