[Object of the Invention] (Industrial Application Field) This invention relates to a method for obtaining a far-infrared emitting ceramic body used as a heat radiator. (Prior technology) Conventionally, far-infrared radiators used in heating and drying equipment are ceramics made of new materials such as high-purity zirconia, alumina, and titania, which exhibit high emissivity in the near-infrared to infrared region. was used, had a structure that was constantly heated at high temperatures, and required sintering at high temperatures to withstand use at high temperatures. Therefore, conventional far-infrared radiators are expensive and difficult to obtain. (Problems to be Solved by the Present Invention) This invention is capable of achieving a suitable wavelength range (particularly far infrared region) at an appropriate temperature without requiring adjustment by sintering at high temperatures.
The aim is to easily obtain an inexpensive far-infrared radiator with an appropriate emissivity by curing it at room temperature. Far-infrared ray-emitting objects that contain a lot of water, such as food, fresh vegetables, seafood, and the human body, have the characteristic of absorbing specific far-infrared wavelengths. For such substances, radiation in the range from near-infrared to infrared is not necessary, but rather far-infrared radiation with longer wavelengths is required. [Means for solving the problem] In order to obtain such a far-infrared emitting ceramic body, materials having radiation characteristics of high emissivity in the far-infrared wavelength region are combined, and have hydration hardening ability at room temperature. Moreover, it can be adjusted by using alumina cement, whose hydrated hardened product does not decompose at high temperatures, as a hardening agent. The fired white porcelain, which is the main component in the ceramics according to the present invention, is a sintered powder having far-infrared function and is easily available. Alumina powder also has a far-infrared radiation function and can be obtained at low cost. Furthermore, silica, nugnesia, ferrous oxide, carbon, and silicon carbide powder added in an amount of 2 to 15% can increase the far-infrared emissivity as a whole. Moreover, the alumina cement added in an amount of 0.5 to 10 has the role of a binder and hardening agent that easily binds these ceramic mixtures at room temperature. That is, a ceramic body made by adding 0.5-10% alumina cement and 5-20% water to the above-mentioned mixed ceramics, kneading and molding the mixture hydrates and hardens by itself at room temperature to become a hard far-infrared emitting ceramic body. This shows a mode of use similar to that of conventional castable refractories. Although the ceramic according to the present invention is not sintered at a high temperature, it is a far-infrared radiator that self-cures at room temperature and has strong bonds, and can be used as a far-infrared radiator as it is. Furthermore, in order to serve the purpose of a high-strength structural material, it can be fired at a high temperature of 1700°C. Incidentally, the current heat resistance limit for unfired products is 1600℃, and the compressive load
It has sufficient strength to withstand 15.6tOn/cm 2 . (Operation of the invention) Ceramics prepared by blending and using alumina cement, which is a feature of the present invention, can be easily hardened and molded into any shape at room temperature, have moderate strength, and have high far-infrared emissivity. There is. The effect of the far infrared rays emitted from the ceramics of the present invention on the radiated material was superior to that of the conventional method. Examples are shown below. (Example) Table 1 shows formulation examples of far-infrared emitting ceramic bodies according to the present invention. The ceramic powder uniformly mixed with these formulations is thoroughly mixed with water in the final step, and the mixture is poured into a predetermined mold and left to dry at room temperature. The ceramic body adjusted in this manner exhibits radiation characteristics that emit far-infrared rays at a high emissivity. The emissivity curves of Blend Example Nos. 1, 3, and 6 are shown in the drawing. The drying effect of far infrared rays emitted from the ceramic body prepared in this way was investigated on meat such as beef and poultry, vegetables, and mushrooms, and the results showed that the drying state and water loss rate of these were mainly due to conventional convection heat transfer. It showed extremely superior results compared to that of hot air drying. At the same time, it also showed an energy saving effect.
