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 e

Abstract

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.

Description

technical field [0001] The present invention relates to a method for producing high-functional new materials from diatomite waste, that is, when waste disposal of diatomite waste discharged from filtration processes in various manufacturing plants, etc., it has good operability, low cost of drying fuel and wasteful residue control. Organic components such as enzymes and yeasts in diatomite can make full use of their functions, etc., and can obtain high-function waste diatom earth at a low cost to manufacture high-function new materials. The present invention also relates to obtaining A high-function new material and a building material composition using diatomaceous earth. Background technique [0002] Diatomaceous earth has been used as a filter material in the filtration process of various manufacturing plants such as breweries or soy sauce factories. For example, breweries process hops in barley wort to add bitterness or aroma, ferment it, and filter it with diatomaceous...

Problems solved by technology

[0016] On the other hand, waste diatomaceous earth used in factories such as the food industry is not new diatomaceous earth, and it is generally entrusted to garbage disposal professionals to landfill it. It is difficult to dispose of because it has a bad smell, and it is a kind of garbage that even professionals want to avoid because of various harsh conditions such as mold and perishability.

Therefore, the processing fee increases year by year, and there is a problem that threatens the manufacturing cost

[0017] In addition, the reuse of waste diatomaceous earth activation treatment is not only very complicated, but also requires high temperature treatment, which consumes a lot of manpower and material resources, so it has not yet been put into practical use.
