본 고안은 금속이온 용출장치에 관한 것으로, 특히 유리에서 나트륨 이온을 용출하는 장치에 관한 것이다.The present invention relates to a device for eluting metal ions, and more particularly to an apparatus for eluting sodium ions from glass.
최근 사무용 기기, 휴대용 계산기 및 텔레비전 등에 액정 표시장치(LCD), 프라즈마 디스플레이(PDP), 형광표시관(VFD) 및 발광 다이오드(LED)의 적용 연구가 활발히 추진되고 일부는 실용화되었다.Recently, researches on the application of liquid crystal displays (LCDs), plasma displays (PDPs), fluorescent displays (VFDs), and light emitting diodes (LEDs) to office equipment, portable calculators, and televisions have been actively promoted, and some have been put into practical use.
이들 디스플레이 소자의 구성은 기본적으로 투명 전극 유리 기판으로 이루어져 있다.The structure of these display elements consists essentially of a transparent electrode glass substrate.
액정표시 장치인 경우 투명전극 유리기판을 기본으로 하는 셀(cell)내에 액정을 주입하고, 전류를 흐르게 작동시킨다.In the case of a liquid crystal display device, a liquid crystal is injected into a cell based on a transparent electrode glass substrate and operated by flowing a current.
이때 기판으로부터 나트륨등의 알카리 성분, 세정액, 에칭 액의 잔유 성분등 전도성 물질이 액정내로 용출하게 되면 액정의 전기적 환경이 변화되어 전류 인가시 액정셀이 단락되는 등의 문제점이 발생하게 된다.At this time, when the conductive materials such as alkali components such as sodium, cleaning liquid, and residual oil components of the etching solution are eluted from the substrate, the electrical environment of the liquid crystal is changed, and the liquid crystal cell is short-circuited when an electric current is applied.
따라서 상기 디스플레이 소자에 사용되는 유리들에 있어서 불순물 특히 나트륨 이온의 용출량을 엄격하게 관리하여야한다.Therefore, in the glasses used in the display device, it is necessary to strictly manage the elution amount of impurities, particularly sodium ions.
유리에서 나트륨 이온이 용출되는 량을 측정하는 방법은 소정의 유리시료로부터 순수로 나트륨을 용출하여 원자 흡광 분석기 또는 이온 프라즈마 분석기와같은 금속이온 측정기로 사용하여 분석한다.The method of measuring the amount of sodium ions eluted from the glass is eluted with pure water from a predetermined glass sample and analyzed using a metal ion meter such as an atomic absorption analyzer or an ion plasma analyzer.
종래에 유리시료로부터 나트륨을 용출시키기 위한 장치는 제1도에서 보듯이 테프론 수지로 된 용기로 구성되어 있으며 이를 이용한 측정방법은, 일정 크기의 유리를 준비하여 그 유리 절단면들을 에폭시, 실리콘 등의 나트륨이 함유되어 있지 않은 접착제를 사용하여 그 절단면들을 접착제로 바르고 일정 용기내에 그 시편을 넣고 순수를 용기 상부까지 채워 일정한 온도에서 일정시간 방치한 후 그 용기에 있는 물을 분자흡광 원자흡광 분석기 또는 이온 프리즈마 분석기로 분석하는 것이었다. 하지만 이 장치는 접착제의 경우 무알칼리 성분의 고가의 접착제를 사용하여야만 하고, 이 또한 구입이 어려우며, 또한 모퉁이면의 완전한 밀봉이 어려운 문제점이 있다. 더욱 용기 역시 고가의 테프론 수지로 되어 있으므로 상기의 장치를 구입 비치하는데 많은 경비가 지출될 뿐만 아니라 용기의 세정시 주의가 팔요하다.Conventionally, a device for eluting sodium from a glass sample is composed of a container made of Teflon resin, as shown in FIG. 1, and a measuring method using the same is prepared by preparing a glass having a predetermined size and removing the glass cut surfaces of sodium, such as epoxy and silicon. Using these adhesives, the cuts are coated with adhesive, the specimens are placed in a container, pure water is filled to the top of the container, and left at a constant temperature for a certain time. The water in the container is absorbed by a molecular absorption atomic absorption analyzer or an ion freeze. The analysis was done with a ma analyzer. However, the device has to use expensive adhesives of non-alkali component in the case of adhesives, which is also difficult to purchase, and also difficult to completely seal the corners. Moreover, since the container is also made of expensive Teflon resin, not only a great expense is required to purchase the above device, but also care is required when cleaning the container.
본 고안은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 저렴한 비용으로 장치를 구성하고, 사용시 보다 편리한, 나트륨 용출장치를 제공하고자 함을 목적으로 한다.The present invention has been made to solve the problems of the prior art as described above, it is an object to configure a device at a low cost, to provide a more convenient, sodium elution device in use.

Thereafter, an O-ring having a diameter of 83 mm was inserted between the glasses for measurement sample.
스테인레스 재질로는 받침대를 유리의 상하면에 밀착시키고 볼트와 너트로 고정시킨후, 주사기를 이용하여 오링상의 지름 1㎜의 구멍을 통하여 오링 내부로 순수(전기 저항: 18㏁)을 주입시킨 후 96℃, 상대습도 80%로 유지되는 항온항습조에 48시간 방치하였다.In stainless material, the pedestal is attached to the upper and lower surfaces of the glass and fixed with bolts and nuts, and then pure water (electric resistance: 18㏁) is introduced into the O-ring through a hole of 1 mm diameter on the O-ring by using a syringe, and then 96 ℃. Incubated for 48 hours in a constant temperature and humidity chamber maintained at a relative humidity of 80%.
