Description
본 발명은 원자번호 22의 원소·원자량47.90의 성질을 갖고있는 물질로서 천연 광물에서 티탄(Titan) 산화물로서 티타니아(Titania) Tio2를 얻는다.The present invention obtains Titania Tio2 as a titanium oxide from natural minerals as a substance having an element-atomic weight of 47.90 having an atomic number of 22.
티타니아는 금속산화물로서 반도체 전극반응과 밀접한 관계를 갖고 있으며 티탄합금으로 내 산화성, 내열성, 인장력 개선용등으로 널리 사용되고 있는 물질이다. 또한 티타니아는 친수성(親水生), 친유성(親油性)이 공존하는 양 친매성의 성질을 동시에 갖고 있다. 더욱이 빛(光)을 받으면 3.2ev(빛의 파장으로 나타내면 320∼400nm)밴드갭 에너지(Band gap Energy) 띠가 형성되면서 여기전자[(e-)anion]가 물과 반응하여 (OH) 수산기를 생성(H2O+h+→OH+H+)각종 유기물들을 강력한 산화력을 갖는 광촉매제의 반응을 이르키게 된다. "즉" OH+Organic Compound(유기화합물)→H2O. CO2유기물질들이 표면에 흡착되어 CO2나 HCl 등 무해한 물질로 분해, 사멸, 소멸 시키게 된다.Titania is a metal oxide that has a close relationship with semiconductor electrode reactions and is a titanium alloy widely used for improving oxidation resistance, heat resistance, and tensile strength. In addition, titania has both hydrophilic and lipophilic properties. Furthermore, when light is received, a band gap energy band of 3.2 ev (320-400 nm in wavelength of light) is formed, and the excitation electron [(e-) anion] reacts with water to form a (OH) hydroxyl group. Produced (H 2 O + h + → OH + H +) The reaction of the photocatalyst with a strong oxidizing power of various organic materials. "Oh" OH + Organic Compound → H 2 O. CO 2 Organic substances are adsorbed on the surface and decomposed, killed and destroyed by harmless substances such as CO 2 and HCl.
이와 같이 티타니아(Titania) Tio2는 387nm 이하의 자외선을 조사하면 광화학 반응이 진행하게 된다. 그러나 Tio2에는 가시광선에는 거의 반응하지 않으므로 천연 광물인 세리사이트(Sericite)를 입자크기 0.2,mm 이내의 입자로 균질화를 한후 광물속에 함유하고 있는 금속산화물을 화학 처리 공법으로 제거시킨 후 Tio2에 코팅을 하는 방법을 도입시키어 원 적외선 방사에 의한 물분자 활성화를 꾀하고 가시광선에서 거의 반응하지 않는 것을 도와주는 역할을 한다.As described above, when Titania Tio 2 is irradiated with ultraviolet rays of 387 nm or less, the photochemical reaction proceeds. However Tio 2 is rarely react to visible light, then removing the metal that is contained in the mineral hanhu natural mineral sericite (Sericite) a particle size homogenizer to particles of less than 0.2, mm oxide with a chemical treatment method in the Tio 2 The coating method is introduced to help activate water molecules by far-infrared radiation and help to hardly react in visible light.
이와 같이 일반적인 촉매는 열역학적으로 가능한 반응계 촉매작용을 하게되며 또한 촉매의 정의와 걸맞지 않은 형태가 도출되고 있다. 그러나 본 발명품은 열역학적으로나 빛의 파장길이로서 불가능한 반응도 빛의 도움을 받아서 가능하도록 하는 특징을 부여 하였으며 광 여기 전자를 받아 정공이 형성되어(e-)anion 불안정한 상태를 만들거나 하여 강력한 산화력을 주는데 이때 자신은 산화하지 않으면서 Organic Compound(유기화합물)들을 산화에만 전념하게 된다.As such, a general catalyst is capable of thermodynamically possible reaction system catalysis, and a form which is not consistent with the definition of the catalyst is being derived. However, the present invention is characterized by thermodynamics or wavelengths of light, which makes it impossible to react even with the help of light. Holes are formed by receiving photo-excited electrons (e-) anion to create an unstable state. Instead of oxidizing, he concentrates on organic compounds.
본 발명은 상기한 지금까지의 문제점들을 감안하여 광촉매제에서 열역학적으로 갖지 못하는 빛의 파장 영역에서도 충분한 역할을 하도록하는 한편 원적외선 방사체로 말미암아 제2단계 반응에 의해 전자가 여기되어 높은 에너지 준위로 올라가며 이때 빛(光)을 받은 물분자는 활성화(活性化) 상태로 바뀌어 일반물의 헤르츠(Hz) 보다 변각이 좁은 64∼80(Hz)를 주게하여 물분자 (H2O)(수소와 수소거리) 활성을 꽤하므로 에너지 준위도가 높아진 전자 프론톤(양성자)과 고 에너지(HiEnergy) 전달체로 환원 시킨다.In view of the above problems, the present invention plays a sufficient role even in the wavelength region of light that is not thermodynamically present in the photocatalyst, while the electrons are excited by the second stage reaction due to the far-infrared radiator, and the electrons are raised to a high energy level. Water molecules that receive light change to an active state, giving 64 to 80 Hz, which is narrower than hertz (Hz) in general, to activate water molecules (H 2 O) (hydrogen and hydrogen distance). This reduces the energy levels to electron protons (protons) and high energy (HiEnergy) carriers.
그러므로 광 에너지(Light Energy)의 변화효율을 향상시키기 위해서는 빛의 흡수가 효율적이어야 하고 광전하(전자와 정공) 가 효율적으로 분리 되어야 하며 , 전자의 최종 포텐셜(Potential) 을 높일 수 있어야 한다.Therefore, in order to improve the change efficiency of light energy, light absorption must be efficient, photocharges (electrons and holes) must be effectively separated, and the final potential of electrons must be increased.
그러므로 광촉매는 광(光) 여기상태에서 분리된 전하를 이용하는 것과 광 여기상태에 대한 불안정한 상태를 이용하는 것으로 나눌 수 있다.Therefore, photocatalysts can be divided into using separate charges in the photo excited state and using an unstable state for the photo excited state.

따라서 원적외선의 물에 미치는 영향을 N·M·R (nuclear magetil resonance) 검사한 결과 일반 수돗물 및 우물물에서는 물 운동의 범위가 150Hz 정도에 있음을 알았고 본 발명품을 통과한 물에는 64Hz∼80Hz범위에 잇는 것을 확인할 수 있었으므로 Hz의 범위가 적을수록 왕복운동이 활발한 것으로서 광촉매의 역할이 커지는 비례성을 알게 되었다.Therefore, the results of Nm.R (nuclear magetil resonance) test on the effect of far infrared rays on water showed that the range of water motion was about 150Hz in general tap water and well water, and it was in the range of 64Hz ~ 80Hz for water passing through the present invention. As a result, the smaller the range of Hz, the more active the reciprocating motion, and the greater the proportion of the photocatalyst.
