Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oxygen activator for activating sterilization or animals and plants by activating oxygen or water in air and water, a method for producing the same, and sterilizing sand. .

[0002]

PRIOR ART The prior application of the present invention is characterized in that a molded article made of a clay containing silicon oxide and alumina as main materials and a small amount of a mixture of refined silicon oxide and potassium oxide is fired at high temperature. An activator and its manufacturing method have been proposed (Japanese Patent Application No. 5-162677).

Ozone is known as a secondary active oxygen, and is used for disinfection, bleaching, oxidation and the like.

[0004]

The oxygen activator of the above-mentioned prior application is used for various purposes (deodorization, fresh water, etc.) and has been well-received, but the certainty of its effect, especially its sustainability and versatility. Or, there was a problem to be improved over a wide range such as manufacturing economy.

Although ozone is an extremely effective substance, it has a problem that it must be manufactured and transported to a necessary place, and it is generally inferior to the product of the prior invention. It was

[0006]

According to the present invention, however, by mixing titanium oxide into porcelain clay, molding it, and firing it at a high temperature, an oxygen activator superior to that of the above-mentioned prior invention was obtained. .

That is, the invention of the product is characterized in that porcelain clay containing silicon oxide and alumina as main components is mixed with 0.3% to 10% of titanium oxide, and a molded product made of this mixture is fired at a high temperature. Is an oxygen activator. The invention of sterilized sand is that porcelain clay containing silicon oxide and alumina as main components is mixed with 0.3% to 10% of titanium oxide, and the mixture is molded into 1 mm to 5 mm. It is a sterilized sand characterized by being fired. Next, the invention of the method is obtained by adding 0.3% to 10% of titanium oxide powder to the powder of porcelain clay containing silicon oxide and alumina as main components and mixing them uniformly, and adding an appropriate amount of water thereto. After molding and drying the viscous material, put it in a firing furnace and slowly raise the temperature.
It is a method for producing an oxidation activator characterized by firing at 0 ° C to 1300 ° C. The firing temperature condition is that the temperature is raised to 900 ° C. for several hours, reduction firing is performed to 900 ° C. to 1000 ° C., and then neutral firing is performed at 1000 ° C. to 1300 ° C.

The above-mentioned clay has the components shown in Table 1, for example.

[0009]

[Table 1]

In the above, the firing temperature of the molded product is 900
When the temperature is not kept at ℃, the degree of activation decreases. Again 130
Even if the temperature is higher than 0 ° C, the characteristics cannot be expected to be further improved.

Further, when the amount of titanium oxide added is 0.3% unfilled with respect to the clay used, a decrease in the degree of activation can be seen. For example, it has been found that a product containing 0.3% of titanium oxide can sufficiently deal with the desorption of the usual odor containing N ₂ . Generally, 0.5% to 5% of the clay is a suitable range, and the addition amount is appropriately selected depending on the purpose of use. In the above, 0.3% to 10% of titanium oxide was mixed in the clay, but titanium oxide was mixed in the clay as well. Therefore, when this is totaled, 0.5% or more of titanium oxide is contained. If this is done, an effect can be expected.

The oxidation activator of the present invention has a wide range of uses such as deodorizing fresh water, sterilizing, and activating animals and plants.
It is used as a molded product such as granular, spherical, polygonal solid, disk-shaped, ring-shaped, etc. depending on the application. The size of the sand varies, but for example, sand has a size of about 0.5 mm to 5 mm, deodorization,
For fresh water, 5 mm to 10 mm or the like is commonly used.

The form of use is to put it in a container made of plastic or the like for deodorization, or put it in a bag of a predetermined amount (1 Kg to 10 Kg) and sell it (sterilized sand etc.). For activation of water and oil, a diameter of 30 mm- 50 mm disk (thickness 3 mm to 5 m
m) Or trade as a ring.

In the invention of the above-mentioned manufacturing method, in order to prevent damage or cracking due to a rapid temperature rise, it is 5 to 6 up to 900 ° C.
The temperature is slowly raised over time.

The titanium oxide decomposes organic chlorine compounds such as trichloroethylene and tetrachloroethylene when used as a titanium oxide photocatalyst, and can decompose phenol, ethylene glycol and polyvinyl alcohol contained in factory wastewater in a short time. .

Methyl mercaptan, dimethyl disulfide, which is generated from fish, garlic, chive, meat, etc.,
It is possible to decompose odorous components of acetaldehyde such as sulfide gas such as dimethyl sulfide and other indoor odors in a relatively short time. It is recognized that the deodorization is a synergistic effect of the far infrared rays generated from the product of the present invention and the catalytic action of titanium oxide, and the deodorizing action can be promoted by additionally using ultraviolet rays.

The product of the present invention has a catalytic effect of titanium oxide and a far-infrared ray effect.
Can be disassembled. Therefore, if it is installed in the room where the air flows in the room (for example, if it is installed on the exhaust side of the air conditioner, it can deodorize and decompose nitrogen oxides, so if it is used together with a known air conditioner, the cleaning can be further improved. .

Since the titanium oxide photocatalyst has a strong oxidizing power, it can be used in combination with far-infrared radiation to sterilize sand in sandboxes, deodorize and sterilize in food factories, and deodorize and sterilize in medical facilities. It can exhibit its characteristics.

Although the characteristics of the titanium oxide photocatalyst are listed above, the product of the present invention radiates far infrared rays, and therefore promotes the catalytic action. Therefore, the amount of titanium oxide mixed can be adjusted according to the purpose of use, and more titanium oxide can be arranged near the surface layer depending on the size or shape of the product.
