Problems solved by technology

[0005] However, at present, the functional ceramic tile products in the Korean market generally have the function of moisture absorption and moisture resistance, but there is a disadvantage that the physical properties such as the strength of the tiles are reduced, and most of them are prepared by prioritizing the style over the function, so it is necessary to develop and ensure moisture absorption. Technology related to ceramic molding system that can prevent moisture and exert strength and physical properties

[0069] Experimental example: Determination of moisture absorption and moisture resistance and bending strength of porous ceramic tiles

[0070] The moisture absorption and moisture resistance and bending strength of the porous tiles of the above-mentioned Examples and Comparative Examples were measured, and the results are shown in Table 3 below.

[0071] 1) Moisture absorption and moisture resistance: at a temperature of 25° C. and a relative humidity (Relative Humidity, RH) of 50%, place the porous ceramic tiles of the above-mentioned examples and comparative examples for 24 hours, and then place them again at a temperature of 25° C. and a relative humidity of 75%. Under relative humidity conditions, maintain 12 hours to measure the weight difference, and again under the temperature of 25 ℃ and 50% relative humidity conditions, after maintaining for 12 hours, measure the weight difference, and convert the average value into unit area. calculate.

[0072] 2) Bending strength...

Abstract

Disclosed is a porous ceramic tile including 15% to 60% by weight of gamma-alumina and 5% to 20% by weight of a glassy chain material.

Description

technical field [0001] The present invention relates to porous ceramic tiles having high strength, high moisture absorption and moisture resistance. Background technique [0002] Recently, due to the high-rise buildings, high heat insulation and high airtightness, the indoor air and the outside air are not forced to circulate, and the quality of the indoor air is reduced. Especially in summer, indoor humidity rises to cause condensation on the windows of the living room or the corners of the indoor walls, and mold, ticks, etc. are generated thereby, thereby inducing respiratory diseases and allergies. [0003] In order to solve this problem, it is necessary to develop building materials for interior decoration that have a humidity adjustment function that absorbs moisture to reduce indoor humidity when the humidity is high, and discharges the absorbed moisture to increase the humidity when it is dry. [0004] In order to maximize the above-mentioned humidity control functio...
