PROCESS FOR PRODUCING NOVEL MATERIAL WITH HIGH FUNCTIONAL CAPABILITY FROM WASTE DIATOMACEOUS EARTH, AND NOVEL MATERIAL WITH HIGH FUNCTIONAL CAPABILITY FROM WASTE DIATOMACEOUS EARTH, AND DIATOMACEOUS EARTH COMPOSITION FOR BUILDING MATERIAL UTILIZING SUCH DIATOMACEOUS EARTH

摘要

There is provided a process for disposal of waste diatomaceous earth discharged from a filtration operation, etc. of various production plants, which process excels in handling easiness and in fuel cost for drying and realizes obtaining of high functional capability at low cost through, for example, holding and controlling of organic components, such as enzymes and yeasts, contained in waste diatomaceous earth and utilization of the functional capability thereof. Further, there is provided a diatomaceous earth composition for building containing a porous inorganic material such as fired diatomaceous earth and a cement for use as a coating material applied to panels, walls, etc. The composition is capable of preventing dew condensation, and is applicable without compulsory pressurization on a wood sheathing by means of coating roller, brush, spray coating, etc. Furthermore, the composition for building without exception is substantially from any color fade-out phenomenon due to coloring by natural soil grains. Still further, a certain effect of powerful photocatalyst redox reaction impact by titanium dioxide exposed to air on the decomposition of harmful pollutants of the atmospheric air is promising by causing the composition to contain a powdery porous inorganic mineral as a main component and titanium oxide as a pigment.
