| Recently, the harm chemical materials, such as Formaldehyde,
Acetaldehyde, VOC et al, in home were injured for health. The materials was not caught the general technology in the order to weak concentration in home. On the other hand, a titanium dioxide(TiO2) photocatalyst is utilized for various fields of environment purification such as decomposition of the harm chemical materials.TiO2 was is stable for the acid and alkali,a low price material, and more safety for health. However, TiO2 photocatalyst can only decompose organic materials and bacterium which exist on the surface of TiO2, but are unable to absorb the materials at a distance. Another hand, it is reported that Hydroxyapatite(HAP) is useful for absorption of bacterium, virus,a materials contained Neutrogena oxide, and Ammonia. But HAP can not decompose organic materials which were absorbed. In other to supplement of a weak point both TiO2 and HAP, We are developed TiO2 coated to HAP which has the ability both absorb and decompose repeatly. And more, we have successes to TiO2 coated on Fluorite(FAP)instituted of HAP. The characters of FAP has be put up with acid solution, and has a large area comparing to HAP. We had been starting to sell a paint had function of photocatalyst which had contained the martial of TiO2 coated on FAP, called Faith guard, Faith guard had characterized as follow: 1)Clear the painted film Technical subject and solution method; for clearing painted film needs to be high dispersion, TiO2 coated on FAP. For the method consideration is made for the best conditions and to become small to specific gra vity, because TiO2 coated on FAP. 2)The paint does not damage basis technical subject and solution method Used only TiO2, for photocatalyst, We recognized using TiO2 will cause decomposition to painted film and basis. For that solution, material, TiO2 coated on HAP particles and not touched to basis. It is possible to ensure long term durability.
Technical subject and solution method; General paint is the remaining ingredient to the inside of the paint film. But at the photocatalyst paint for surface reaching to a toxic chemical substance and photocatalyst TiO2 coated on FAP has tostay on painted filmfs surface. For the solution, we carried out, giving high dispersion to TiO2 coated on FAP and examine physical characteristics as glass transitionfs paint, as well as examining the most suitable requirement of paint mixture. 4)Be able to select the paint by purpose Technical subject and solution method; There is the case, interior and exterior is one paint, But for photo catalyst pa-int it cannot be together for interior and exterior because it is very delicate effectiveness. Further need to deal with bad smelling of toilet. For that reason the TiO2 coated on FAP paint(Faith guard). We examined kinds of binder in paint, quantity and additive. 5)Stable quality TiO2 coated on FAP is the same as Faith guard, but ensure stable quality by checking each produced rod, management function and management value. 6)Great inexpensive About acknowledgement of paint Pass the strict examination for NPO hconsidering sick househ. And registered data base. Regarding to the the martial of TiO2 coated on FAP, and the paint ,Faith guard
