  • the generated quicklime comes into contact with moisture through a moisture absorption process of the porous ceramic tile, and thus, a process of providing antibacterial activity is as described above.
  • the pyrolysis may be carried out at a temperature of about 800 °C to about 1000 °C. Although not limited to the temperature of the pyrolysis, it is possible to form a porous ceramic tile of the previous stage exhibiting antimicrobial activity by performing pyrolysis at the temperature of the above range.
  • the pyrolysis may be performed for a time of about 1 minute to about 15 minutes.
  • the heat treatment outside the pyrolysis time may not be sufficiently pyrolysis. Therefore, by performing pyrolysis for the above range of time, it is possible to form a porous ceramic tile of the previous stage exhibiting antimicrobial properties, and may have advantages in terms of production and energy costs.
  • porous ceramic tile manufacturing method it is possible to deform the antimicrobial active material by undergoing the pyrolysis and firing step (S400), evenly distributed on the porous ceramic tile as a previous step that can exhibit antimicrobial activity. Thereafter, by using the porous ceramic tile, the surface of the pores is basified through a hygroscopic process, and thus the antimicrobial property may be naturally given to the porous ceramic tile.
  • the mixture of the components shown in Table 1 was ground using a ball mill, and the slurry thus obtained was uniformly mixed through a spray drying process to prepare spherical granular powder having a water content of 8% and an average particle size of 300 ⁇ m.
  • porous ceramic tiles having a width, length, and thickness of 7 cm, 7 cm, and 0.6 cm, respectively.
  • the porous ceramic tile was dried in a continuous drying furnace at 250 ° C., and frit powder and pigments having an average particle size of 15 ⁇ m and a degree of fluorescence of 750 ° C. were dispersed in water and spray-coated.
  • the oiled porous ceramic tile was introduced into a gas continuous furnace (RHK), and thermally decomposed and baked at a temperature of 850 ° C. for 10 minutes to prepare a porous ceramic tile having an average pore diameter of 5 nm and a porosity of 45%.
  • RHK gas continuous furnace
  • a porous ceramic tile was manufactured in the same manner as in the above example, except that the antimicrobial active material was not included in the components shown in Table 1 below.
  • the porous ceramic tiles of the examples and comparative examples were soaked in water (100 ml) at 25 ° C. for 10 minutes. Thereafter, the ions are present in the pores included in the porous ceramic tile over time. At this time, the pH value of the pore surface was measured using a pH meter, and the results are shown in Table 2 below.
  • the pore surface of the porous ceramic tile exhibits basicity of pH 11 or more at a relatively fast time, and the porous ceramic tile is room temperature. Due to moisture absorption during use, the surface of the pores is made basic, which can be inferred to increase antibacterial and antifungal performance.
  • the pH of the pore surface of the porous ceramic tile stopped at about 9, indicating no basicity.
  • they do not exhibit antimicrobial performance such as bacterial growth deterioration that may occur during use of the porous ceramic tile.
