By forming a micro-battery and immersing the micro-battery in water or an aqueous solution, it has been conceived that copper ions are continuously dissolved in water or an aqueous solution due to a potential difference between both substances.

面で水素イオンと結合して水素ガスが発生する。That is, when a copper substance and a carbon substance are immersed in water, the copper dissolves in the water as copper ions, the electrons remaining in the copper substance move to the carbon substance, and the electrons are converted into hydrogen on the surface of the carbon substance. Combined with the ions, hydrogen gas is generated.

ら、この銅イオンによって抗菌脱臭作用が発現する。That is, copper ions are dissolved from the surface of the copper substance, and the copper ions exert an antibacterial action and a deodorizing action. On the other hand, hydrogen gas is generated from the carbon material surface. Even if the copper and carbon materials are not immersed in water, just placing the copper and carbon materials in contact in high-humidity air will dissolve the copper ions in the water adhering to the surfaces of both materials. The copper ions exert an antibacterial and deodorizing action.

成分を吸着して脱臭作用を発揮することができる。When a copper substance and a carbon substance are placed in dry air in contact with each other, moisture does not adhere to the surfaces of both substances, so that copper ions do not dissolve. Is difficult to demonstrate. However, since the carbon material has a myriad of micropores (micropores) on the surface, it can exhibit odor components by adsorbing odor components.

となって吸着作用を発現する。In order to improve the adsorption performance of the carbon material itself, it is desirable that the carbon material be composed of an activated carbon material. Activated carbon is a substance obtained by performing an activation treatment on a normal carbon substance. Innumerable micropores of nanometer size are formed on the surface of the carbon substance, and the micropores serve as adsorption points to exhibit an adsorption action.

Since the powders are mixed, countless pairs in which the copper material particles and the carbon material particles are in contact with each other are formed, and each pair forms a microcell, so that countless microcells are formed.

る。Further, in the present invention, by combining a powder mixture of a copper substance and a carbon substance with another deodorant or an antibacterial agent, it is possible to eliminate odor components which are hardly eliminated by copper ions, thereby improving antibacterial activity. The deodorization power is further improved.

き、この遠赤外線放射セラミックスは湯の温度に相当す
る熱エネルギーを吸収して遠赤外線を放射する。First, far-infrared radiation ceramic powder is added to a powder mixture of a copper substance and a carbon substance. When the antibacterial deodorizing material according to the present invention is immersed in, for example, hot water in a bathtub, the far-infrared radiation ceramics absorbs thermal energy corresponding to the temperature of the hot water and emits far-infrared rays.

The far infrared ray of 0 μm has an extremely high activating effect on water and hot water and a bactericidal and preservative effect. When the hot water is activated, the hot water also has a function of coagulating a dirt substance in the hot water to increase the transparency, and removing the dirt on the wall surface to cause coagulation and sedimentation.

Hot water and water can be kept clean for a long time.
This disinfecting and preserving action is synergistic with the disinfecting and deodorizing action of copper ions to maintain the cleanliness of water and hot water.
