본 발명은 마그네슘합금 안경테의 세정방법에 관한 것으로서, 더욱 상세하게는 세정액으로 물을 이용함으로써 친환경적으로 안경테를 용이하게 세정할 수 있도록 하는 마그네슘합금 안경테의 세정방법에 관한 것이다.The present invention relates to a method of cleaning magnesium alloy spectacle frames, and more particularly, to a method of cleaning magnesium alloy spectacle frames to facilitate the environmentally friendly cleaning of the spectacle frames by using water as the cleaning liquid.
일반적으로 마그네슘합금은 치수 안정성이 우수하고, 미강도, 전자기파 차폐 성, 진동 감쇄 등이 알루미늄 합금과 철강에 비하여 우수하여 자동차와 항공기용 부품, 휴대폰 케이스, 노트북 컴퓨터 케이스, 안경테 등에 많이 사용되고 있다.In general, magnesium alloy has excellent dimensional stability, and excellent strength, electromagnetic shielding, and vibration damping are superior to aluminum alloys and steels, and are widely used in automobile and aircraft parts, mobile phone cases, laptop computer cases, and eyeglass frames.
예컨대 안경테 등을 마그네슘합금으로 제조할 때, 다이캐스팅 주조를 이용하게 되며, 다이캐스팅 주조 방식으로 안경테 등을 제조하게 되면 표면 조직의 치밀성이 저하됨과 더불어 산화가 매우 잘되기 때문에, 필수적으로 표면을 처리하기 위한 세정 공정이 발생하게 된다.For example, when manufacturing a spectacle frame such as magnesium alloy, die casting casting is used. When the spectacle frame is manufactured by a die casting casting method, the density of the surface structure is degraded and the oxidation is very good. A cleaning process will occur.
여기서 상기와 같은 세정 공정은 포밍 공정, 트리밍 공정, 기계 가공 및 사상 공정을 거친 안경테 등을 코팅이나 도장하기 전에 처리하는 공정으로서, 종래에는 알칼리 용액, 크롬산염 용액 등과 같은 세정액을 이용하여 안경테 등의 표면을 처리하게 된다.Here, the cleaning process as described above is a process of treating the eyeglass frame after forming, trimming, machining and finishing before coating or painting, and conventionally, such as eyeglass frames using a cleaning solution such as an alkaline solution or a chromate solution. The surface will be treated.
그러므로 종래에는 알칼리 용액 등으로 안경테를 세정하기 때문에, 세정한 후에 발생되는 알칼리 용액 등이 친환경적이지 못하여 토양이나 강물을 오염시켜서 환경 오염을 유발한다는 단점이 있다.Therefore, in the related art, since the spectacle frame is cleaned with an alkaline solution or the like, the alkaline solution generated after the cleaning is not environmentally friendly and contaminates soil or river water, thereby causing environmental pollution.
물론 상기와 같은 세정액을 별도로 처리하거나 재활용할 수도 있으나, 이러한 세정액을 처리하거나 재활용하기 위한 처리 시설에 많은 비용이 소요되는 것이다.Of course, the cleaning solution as described above may be separately processed or recycled, but a high cost is required for a treatment facility for treating or recycling such cleaning solution.
본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 마그네슘합금 재질로 성형 및 가공되는 안경테를 환경에 아무런 악영향을 미치지 않는 물을 이용하여 세정함으로써 안경테를 친환경적으로 용이하게 세정할 수 있는 마그네슘합금 안경테의 세정방법을 제공하는 데 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to clean the eyeglass frame environmentally by cleaning the eyeglass frame molded and processed with magnesium alloy using water does not adversely affect the environment The present invention provides a method for cleaning a magnesium alloy eyeglass frame that can be easily cleaned.
이를 실현하기 위하여, 본 발명은 도장하거나 코팅하기 전에 마그네슘합금 재질의 안경테를 세정함에 있어서, 95℃ ~ 100℃의 물에 안경테를 넣고, 다수의 브러쉬를 회전시켜 안경테의 표면을 10분 ~ 60분동안 처리하는 것으로 이루어지는 마그네슘합금 안경테의 세정방법을 제공한다.In order to realize this, the present invention in cleaning the frame of magnesium alloy material before painting or coating, put the frame in water of 95 ℃ ~ 100 ℃, and rotate the surface of the brush to a plurality of brushes 10 minutes to 60 minutes Provided is a method for cleaning a magnesium alloy spectacle frame, which is treated during the process.
이하 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 더욱 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
도 1과 도 2는 본 발명에 의한 마그네슘합금 안경테의 세정방법을 설명하기 위한 도면으로서, 본 발명의 세정방법이 적용되는 마그네슘합금 안경테는 포밍 공정, 트리밍 공정, 기계가공 공정, 사상 공정, 세정 공정, 도장 및 조립 순으로 제조되며, 추가적으로 상기 사상 공정 후에 쇼트 공정을 포함할 수도 있다.1 and 2 are views for explaining the cleaning method of the magnesium alloy spectacle frame according to the present invention, the magnesium alloy spectacle frame to which the cleaning method of the present invention is applied, forming process, trimming process, machining process, finishing process, cleaning process It is manufactured in the order of painting and assembling, and may further include a short process after the finishing process.
여기서 본 발명에 의한 마그네슘합금 안경테의 세정방법은 도장하거나 코팅하기 전에 마그네슘합금 재질의 안경테(1)를 세정하는 것으로서, 95℃ ~ 100℃의 물에 안경테(1)를 넣고, 다수의 브러쉬(2)를 회전시켜 안경테(1)의 표면을 10분 ~ 60분동안 처리하는 것으로 이루어진다.Here, the magnesium alloy spectacle frame cleaning method according to the present invention is to clean the spectacle frame (1) made of magnesium alloy material before coating or coating, and put the spectacle frame (1) in water of 95 ℃ ~ 100 ℃, a plurality of brushes (2 Rotate) to treat the surface of the spectacle frame 1 for 10 to 60 minutes.
또한 세정 시간을 최소화하기 위하여, 1.0중량% 이하의 소금을 물속에 혼합하는 것을 포함한다.It also includes mixing 1.0 wt% or less of salt in water to minimize cleaning time.
여기서 세정에 사용되는 물의 온도가 95℃보다 낮으면 세정 시간이 많이 소요되어 전체 공정에 소요되는 시간이 증대하여 비효율적이고, 100℃보다 높으면 안 경테 표면의 부식이 빨리 진행되어 표면이 매끄럽지 못하게 된다.Here, if the temperature of the water used for cleaning is lower than 95 ℃ takes a lot of cleaning time, the time required for the entire process increases inefficient, if it is higher than 100 ℃ the corrosion of the surface of the frame proceeds quickly and the surface is not smooth.
또한 세정 시간이 10분보다 짧으면 표면을 바람직하게 처리하지 못하며, 60분보다 길면 불필요한 시간을 소요하게 된다.In addition, if the cleaning time is shorter than 10 minutes, the surface is not treated preferably, if it is longer than 60 minutes takes unnecessary time.
그리고 소금의 함량이 1.0보다 크면 부식 진행 속도가 빨라서 안경테(1) 표면이 검게 되어 불량이 발생할 수 있는 것이다.And when the salt content is greater than 1.0, the corrosion progress is fast, the surface of the spectacle frame (1) is black and may cause a defect.
아무튼 상기와 같은 마그네슘합금 안경테를 제조하는 공정을 살펴보면서 본 발명의 세정 방법을 설명하면 다이캐스팅 포밍 공정에서는 용융상태의 Mg합금을 금형에 고압으로 충전시키고 급속 냉각시켜 안경테를 성형하여 안경테의 요구사항에 따라 표면 품질 또는 내부 밀도를 최적화하게 되고, 트리밍 공정에서는 주조공정에서 생기는 게이트(Gate), 러너(Runner), 오버플로우(Over Flow) 등 제품 형상 이외의 부분을 기계로 따내서 안경테의 원형만을 얻게 된다.Anyway, the method of manufacturing the magnesium alloy spectacle frame as described above describes the cleaning method of the present invention. In the die-casting forming process, the molten Mg alloy is charged to the mold at high pressure and rapidly cooled to form the spectacle frame according to the requirements of the spectacle frame. The surface quality or internal density is optimized, and in the trimming process, parts of the frame other than the product shape such as gates, runners, and overflows are removed by the machine to obtain only the prototype of the spectacle frame. .
그리고 기계가공공정에서는 트리밍 공정으로 가공된 안경테를 드릴링, 탭핑 등으로 구멍을 뚫고 나사구멍을 형성하게 되며, 사상 공정에서는 주조 및 가공 공정 중에 발생하는 안경테 가장자리의 버르(Burr) 또는 표면의 플래쉬(Flash) 등을 제거하고 제품의 외관을 확보하게 된다.In the machining process, the eyeglass frame processed by the trimming process is drilled by drilling, tapping, etc. to form a screw hole, and in the finishing process, the burr or the surface flash of the edge of the eyeglass frame generated during the casting and processing process is flashed. ) To secure the appearance of the product.
상기와 같이 사상 공정으로 처리된 안경테를 본 발명의 세정 방법으로 세정 공정을 진행하게 되는 바, 세정 공정에서는 안경테의 표면에 있는 미세입자(Particle)를 떨어뜨림과 더불어 표면을 매끄럽게 하고, 안경테의 내식성을 확보하고, 도장 원료와의 밀착력을 향상시키는 것이다.As described above, the eyeglass frame treated by the finishing process is subjected to the cleaning process according to the present invention. In the cleaning process, the surface of the eyeglass frame is dropped and the surface is smoothed. To improve the adhesion to the coating material.
즉 물속에 안경테(1)를 고정한 뒤, 모터(3)로 회전되는 브러쉬(2)로 안경 테(1)의 표면의 미세입자를 긁으면서 안경테(1)의 표면을 닦아서 물속에서 안경테(1)의 표면층을 미세하게 녹이면서 브러쉬(2)로 미세입자를 떨어뜨리게 된다.That is, after fixing the spectacle frame (1) in the water, and wipe the surface of the spectacle frame (1) while scratching the fine particles of the surface of the spectacle frame (1) with a brush (2) rotated by a motor (3) in the water frame (1) While finely melting the surface layer of the fine particles will be dropped into the brush (2).
그러면 도 3과 같은 상태의 안경테 표면을 도 4와 같은 안경테 표면으로 처리할 수 있다.Then, the spectacle frame surface as shown in FIG. 3 may be treated with the spectacle frame surface as shown in FIG. 4.
즉 도 3과 같이 안경테의 표면에는 많은 양의 미세입자가 부착되어 있어 매우 거칠다고 할 수 있으나, 이를 본 발명의 세정 방법으로 처리한 뒤인 도 4에서는 매우 깔끔하게 처리되는 것이다.That is, a large amount of fine particles are attached to the surface of the spectacle frame as shown in FIG. 3, but it can be said to be very rough. In FIG.
이상 설명한 바와 같이, 본 발명에 의한 마그네슘합금 안경테의 세정방법은 마그네슘합금 재질로 성형 및 가공되는 안경테를 환경에 아무런 악영향을 미치지 않는 물로 안경테의 표면층을 녹이면서 브러쉬로 긁거나 닦아내기 때문에, 마그네슘합금 재질의 안경테를 세정한 세정액으로 인하여 발생되는 토양과 강물의 오염을 방지하여 안경테를 친환경적으로 용이하게 세정할 수 있다는 이점이 있다.As described above, the magnesium alloy spectacle frame cleaning method according to the present invention is a magnesium alloy because it is scraped or wiped with a brush while melting the surface layer of the spectacle frame with water that does not adversely affect the environment is molded and processed with magnesium alloy material, Preventing contamination of soil and rivers generated by the cleaning solution for cleaning the spectacle frame of the material has the advantage that the spectacle frame can be easily eco-friendly.
