Abstract
Disclosed is a moisture regulating ceramic material production method which includes the following process steps: mixing starting powders containing sepiolite and reactive alumina sulfate; grinding the starting powders; obtaining granules by dry granulation using alkaline solution with the starting powders; carrying out a pressing process of the granules; and obtaining the materials.
Claims23
A method for producing a moisture-regulating ceramic material, the method comprising:
- mixing a sepiolite and a reactive alumina silicate to form a starting powder;
- grinding the starting powder;
- adding an alkaline solution to the starting powder;
- obtaining granules by dry granulation of the alkaline-added starting powder;
- pressing the obtained granules, wherein a weight ratio of the sepiolite and the reactive alumina silicate and the alkaline solution are between 4.5% to 7.5% and 26% to 29% and 54.5% to 64%, respectively;
- adding 3% to 10% by weight of the boron-containing material to the starting powder or alkaline solution;
- and
- geopolymerizing a structure obtained by the pressing of the granules at a temperature of between 25° C. and 250° C. in an environment of at least 50% humidity for a period of time of between two hours and twenty-four hours.
