项目摘要

In this study, the systematic application technologies that include fundamental technology and processing technology were investigated for natural zeolite. Development engineering that is bioreactor, antibacterial deodorant, ameliorant, electrode, Far Infrared Rays (FIR) radiation body, remover for wastewater treatment and Electro-Magnetorheological Fluids were constructed for practical uses.In consequence, it is clear that a natural zeolite was transferred to zeolite P1 by the alkali treatments. Hygroscopic property was improved as an absorbent material. A natural zeollte, easily vitrifed and blown at 1300 degree with a high porosity and diameter of 5-100 um, was used to immobilize Saccharomyces cerevisiae at 3. 6 *10^8 cells/ml carrier. When the abilities of natural zeolite carrier were compared with glass beads, the capacity for immobilization and alcohol fermentation activity were, respectively, 2'-fold higher and 1. 2-hold higher than that of glass beads. In the meantime, we made the electrode that had electric conductivity and ion absorption from the sinter of a carbon powder and a natural zeolite. We constructed the method to make the FIR radiaton body using a naturai zeolite and the characteristics of radiation body were evaluated. In addition, this radiator was used as FIR radiation light source, and thermography inspection of the breast cancer was tried. From the thermal camera image, the result showed that the temperature of the cancer that reached the skin difters from the temperature of the normal tissue. Simultaneously, it was proven that it might be able to guess the progress of the cancer from the difference of cancer and temperature change pattern of the normal tissue. We examined the adsorptivity of a zeolite in terms of crystallographically and evaluated a soil conditioner property of a natural zeolite by a cultivation test.

本研究对天然沸石的基础技术和加工技术进行了系统的应用研究。构建了生物反应器、抗菌除臭剂、改良剂、电极、远红外线辐射体、废水处理去除剂和电磁流变液等开发工程，并进行了实际应用，结果表明，碱处理使天然沸石转化为P1沸石。作为吸收材料，吸湿性得到改善。使用天然沸石在3. 0 ℃下固定酿酒酵母，该沸石易于在1300度下玻璃化和吹制，孔隙率高，直径为5-100 μ m。6 *10^8个细胞/ml载体。与玻璃微珠相比，天然沸石载体的固定化能力和酒精发酵活性分别提高了2 '-倍和1。2-比玻璃珠高。同时，我们从碳粉和天然沸石的烧结物中制备了具有导电性和离子吸收性的电极。提出了用天然沸石制作远红外辐射体的方法，并对辐射体的性能进行了评价。此外，该辐射器被用作远红外辐射光源，并尝试了乳腺癌的热成像检查。从热成像仪的图像来看，结果表明，到达皮肤的癌症的温度与正常组织的温度不同。同时，也证明了它可以从癌组织和正常组织的温度变化模式的差异来推测癌症的进展。我们从结晶学角度研究了沸石的吸附性，并通过培养试验评价了天然沸石的土壤改良剂性能。
