이붕화티탄이 함유된 세라믹 제조방법 및 세라믹{Manufacturing Method of Ceramic containing Titanium Boride, and Ceramic}Manufacturing Method of Ceramic Containing Titanium Boride, and Ceramic

본 발명은 황토와 감람석 및 이붕화티탄(TiB2;Titanium Boride)을 적절한 크기로 분쇄하여 혼합 성형한 후 건조공정을 거쳐 건조된 성형물을 1000℃~1100℃온도에서 소성함으로써 황토에 감람석과 이붕화티탄이 함유된 세라믹 제조방법 및 세라믹에 관한 것으로, 상기와 같은 제조방법에 의해 얻어지는 세라믹 소재는 화학적 처리와 광촉매반응에 의해 물속에 용해된 유기물, 질소와 인 및 대기 중의 질소산화물 등 오염물질을 동시에 정화 및 제거하며, 상기 제거 대상 오염물질의 농도에 따라 감람석의 혼합비율을 조절함으로써 제거 효율을 높일 수 있고, 또, 청천시에는 우천시 흡착된 유해물질을 무해화하는 기능을 가지며, 지속적으로 비가 오는 경우에도 비가 오지 않을 때 무해화된 물질을 세척하게 되어 별도의 유지관리가 필요 없는 것이다.In the present invention, olivine, olivine and titanium diboride (TiB 2; Titanium Boride) are pulverized to an appropriate size, mixed and molded, and then dried through a drying process at 1000 to 1100 ° C. The present invention relates to a ceramic manufacturing method and a ceramic containing titanium, wherein the ceramic material obtained by the above-described manufacturing method simultaneously contains organic substances dissolved in water by chemical treatment and photocatalytic reaction, pollutants such as nitrogen and phosphorus, and nitrogen oxides in the atmosphere.

일반적으로 환경오염 개선 기술분야는 수질개선 분야와 대기질 개선 분야로 두 개의 범주로 구분되며, 상기 수질개선분야는 생물학적 처리와 화학적 처리로 구분되며, 본 발명중에서 수중의 질소와 인 및 유기물 제거는 화학적 철에 포함된다고 할 수 있다.In general, environmental pollution improvement technology is divided into two categories: water quality improvement and air quality improvement, and the water quality improvement is divided into biological treatment and chemical treatment. In the present invention, the removal of nitrogen, phosphorus, and organic matter from water is It can be said to be included in chemical iron.

또, 상기 대기질개선분야는 대기오염도를 나타내는 대표 지수인 질소(NO2)를 제거하기 위한 것으로 대기 중 질소(NO2)의 주된 발생원은 서울의 경우 72%, 전국은 42%로써 자동차 배기가스가 주요 발생원이라 할 수 있는데, 이를 효과적으로 질소를 제거하는 방법이 제대로 제시되지 못하고 있는 실정이다.In addition, the field of air quality improvement is to remove nitrogen (NO 2 ), which is a representative index representing air pollution, and the main sources of atmospheric nitrogen (NO 2 ) are 72% in Seoul and 42% in the nation. Is the main source, which is not properly proposed to remove nitrogen effectively.
