In particular, the present invention is a method of oxidizing toxic substances by generating OH radicals using Tio2 powder and ultraviolet energy as one of the advanced oxidation methods, which is a new treatment method that deviates from the existing treatment method in treating various pollutants. It relates to a method for producing a Tio2 photocatalyst reactor plate to generate as much OH radicals as possible.
종래 Tio2분말 고정화 방법에서는, 분말이 접착제에 침적이 되는 상태로 촉매 역할이 방해를 받았고, 졸 용액의 경우 다공질의 세라믹이 아니면 경도가 형성되지 않았으며 세라믹의 박판은 파손이 잘되고 비교적 고가로 비경제적이라는 단점이 있었다.In the conventional Tio2 powder immobilization method, the catalyst role is hindered as the powder is deposited on the adhesive, and in the case of the sol solution, the hardness is not formed unless the ceramic is porous, and the thin plate of the ceramic is easily damaged and relatively expensive and uneconomical. There was a disadvantage.
따라서, 본 발명의 목적은 접착제 사용으로 인한 촉매의 침적상태가 없는 이산화티타늄 분말의 고정화 방법 및 이산화티타늄 광촉매 반응기판 을 제공하는 것이다.Accordingly, it is an object of the present invention to provide a method for immobilizing titanium dioxide powder without a catalyst deposit due to the use of an adhesive and a titanium dioxide photocatalyst reactor plate.

상기와 같은 문제점을 해소하기 위해, 본 발명에서는 이산화티타늄 광촉매 반응기판을 접어도 파손이 되지 않는 세라믹 종이 형태로 제작한다. 상기 본 발명의 목적은, 천연 석분을 900℃-1,400℃ 열에 항균 처리하여 산화구리 분말과 혼합하는 단계; 종이 상부면에 접착제를 도포한 다음, 접착제 위에 상기 석분과 산화구리 분말의 혼합 분말을 도포하는 단계; 상기 종이 하부에서 진공 흡착하여 상기 혼합 분말을 고착하고 상온에서 건조시켜 세라믹 페이퍼를 제조하는 단계; 아나타제형 이산화티타늄 분말을 메탄올에 적가시켜 졸 용액을 만든 다음 상기 세라믹 페이퍼에 롤러 전사 방법으로 졸 용액을 고정시키는 단계; 및 상온에서 건조하는 단계로 구성되는 이산화티타늄 분말의 고정화 방법에 의해 달성된다.In order to solve the above problems, in the present invention, the titanium dioxide photocatalyst reactor plate is manufactured in the form of ceramic paper which does not break even when folded. An object of the present invention, the step of mixing the natural stone powder with copper oxide powder by antibacterial treatment at 900 ℃ -1,400 ℃ heat; Applying an adhesive to an upper surface of the paper, and then applying a mixed powder of the stone powder and the copper oxide powder on the adhesive; Vacuum adsorbing the lower portion of the paper to fix the mixed powder and to dry at room temperature to prepare ceramic paper; Adding anatase type titanium dioxide powder to methanol dropwise to form a sol solution, and then fixing the sol solution to the ceramic paper by a roller transfer method; And it is achieved by the method of immobilizing the titanium dioxide powder consisting of a step of drying at room temperature.
이러한 방법으로 제조된 촉매판은 내구성이 강하고 장기 사용시 발생될 수 있는 탈리 현상을 극복할 수 있었다.The catalyst plate manufactured in this way was durable and could overcome the detachment phenomenon that may occur in long term use.
이하 본 발명을 실시예를 통해 상세하게 설명한다.Hereinafter, the present invention will be described in detail through examples.
경도 7이상의 천연 석분을 입도 5-1000 마이크로 정도로 분쇄한다. 선별과정을 거쳐 바람직하게는 20마이크로의 입도를 갖는 석분을 900℃-1,400℃ 고열에 항균 처리후 산화구리 분말과 5-30:1의 비율로 혼합한다. 볼밀, 진동밀, 또는 기타의 믹서로 혼합하여 혼합분말을 준비한다. 1mm 종이의 평면에 무기계의 접착제를 도포, 상기 혼합 분말을 살포하여 종이 하부에 설치된 진공 흡착 장치로 흡착·건조하여 세라믹 페이퍼를 완성하고, 그 표면의 거친 요철 부분에, 아나타제형 이산화티타늄 분말을 메탄올에 적가시켜 만든 졸 용액을 롤러 전사방식으로 Tio2 도막층을 형성케하여 완성한다.Natural stone powder with a hardness of 7 or more is ground to a particle size of 5-1000 microns. Through the screening process, the stone powder having a particle size of 20 microns is preferably mixed with copper oxide powder at a ratio of 5-30: 1 after antibacterial treatment at 900 ° C-1,400 ° C high temperature. Prepare a powder by mixing with a ball mill, vibration mill or other mixer. Applying an inorganic adhesive on a plane of 1 mm paper, spraying the mixed powder and adsorbing and drying with a vacuum adsorption device installed at the bottom of the paper to complete the ceramic paper, and the anatase type titanium dioxide powder was applied to the rough uneven portion of the surface of the methanol. The sol solution prepared by dropwise addition is completed by forming a Tio2 coating layer by roller transfer.
상기와 같은 수단으로 고정화된 광촉매 기판은 접착제 사용으로 인한 침적상태가 전무하여 Tio2분체가 자유로이 광촉매 여기 반응을 할 수 있어 많은 OH 라디칼을 발생시킨다.The photocatalytic substrate immobilized by the above means has no deposition state due to the use of an adhesive, and thus the Tio 2 powder can freely react with the photocatalytic excitation to generate many OH radicals.
도 1 에는 본 발명의 고정화 방법을 설명하기 위해 본 발명에 의해 제조된 기판의 구조가 개략적으로 도시되어 있다. 하부에 종이 층이 있고, 그 위에 세라믹층(석분)이 접착제 및 진공 흡착 장치에 의해 고정화되어 있고, 그 위에 Tio2도막층이 형성되어 있다.Figure 1 schematically shows the structure of a substrate produced by the present invention to explain the method of immobilization of the present invention. There is a paper layer in the lower part, the ceramic layer (stone powder) is immobilized on it by an adhesive agent and a vacuum adsorption apparatus, and the Tio2 coating layer is formed on it.
도 2 내지 도 4에는 본 발명의 원료 및 본 발명의 상기 실시예에 의해 실제 제조된 제품의 SEM(주사형 전자현미경:Scanning Electroon Microscope) 사진이 게시되어 있다. 도 2는 본 발명에 의해 제조된 Tio2광촉매 반응기판 단면의 SEM 사진이고, 도 3은 원료 이산화 티탄의 SEM 사진, 도 4는 이산화티탄 도포막 표면의SEM 사진이다.2 to 4 show SEM (Scanning Electron Microscope) photographs of the raw materials of the present invention and the products actually manufactured by the above embodiments of the present invention. FIG. 2 is a SEM photograph of a cross section of a Tio2 photocatalyst reactor plate prepared according to the present invention, FIG. 3 is a SEM photograph of a raw material titanium dioxide, and FIG. 4 is a SEM photograph of a titanium dioxide coating film surface.
아나타제형 이산화티타늄 광촉매가 고정화된 패널표면 20Cm ∼ 25Cm정도의 근거리에 400nm이하의 자외선(에너지)빛을 조사하면 전기에너지 36,000KW에 상당하는 열자가 생성된다.When the anatase type titanium dioxide photocatalyst is irradiated with ultraviolet (energy) light of 400 nm or less at a short distance of 20Cm to 25Cm on the panel surface, a heating element corresponding to 36,000KW of electric energy is generated.
이러한 열자에 의해 오염된 유기물은 분해되어 무기물로 바뀌는 것이다.Organics contaminated by these heats are decomposed into inorganic matters.
이상에서 서술한 바와 같이, 본 발명의 방법에 의해 제조된 이산화 티타늄이 고정화된 광촉매 기판은 재단과 부착이 용이하고 접어도 파손이 안되며 박판으로 무게가 가벼우며 복층 설계시 많은 비표면적을 얻을 수 있고 제조비용이 저렴하며 경제적이다.As described above, the photocatalyst substrate immobilized with titanium dioxide prepared by the method of the present invention is easy to cut and adhere, does not break even when folded, is light in thin plate, and a large specific surface area can be obtained in the multilayer design. Manufacturing cost is low and economical.
본 발명의 이산화 티타늄이 고정화된 광촉매 기판은 살균, 탈취, 항균, 공기청정 장치 등에 이용되며 그 외에도 대기 중의 질소 산화물(NOX), 황산화물(SOX) 등도 무해화된다. 또한 축산 농가의 전염병 예방, 병원내부의 무균화, 주거공간의 공기청정, 화장실의 살균탈취, 식당 주방의 환경 청결, 자동차내부의 악취제거 등 환경 산업 전반에 걸쳐 헤아릴 수 없는 다양한 용도로 사용된다.The photocatalyst substrate on which the titanium dioxide of the present invention is immobilized is used for sterilization, deodorization, antibacterial, and air cleaning devices. In addition, nitrogen oxides (NOX), sulfur oxides (SOX), etc. in the atmosphere are also harmless. It is also used in countless applications throughout the environmental industry, including the prevention of infectious diseases in livestock farms, aseptic inside of hospitals, air cleaning in residential areas, sterilization and deodorization of restrooms, cleanliness of restaurant kitchens, and removal of odors in automobiles.
