METHOD FOR MANUFACTURING CERAMIC TILES DECORATED WITH DRY PARTICLES TO GIVE THREE-DIMENSIONAL PATTERNS

The present disclosure relates to a ceramic tile decorated with dry particles to give a three-dimensional pattern and a manufacturing method thereof. The manufacturing method comprises the steps of A: glazing a surface of a green body with a ground coat; B: decorating a surface of the ground coat of the green body to form a pattern; C: drying the green body; D: embellishing the green body with dry particles; E: spraying a protective glaze on the surface of the green body; and F: firing the green body after the green body is sprayed with the protective glaze of step E to produce the ceramic tile decorated with dry particles. The manufacturing method can make the ceramic tile produced have a clear pattern, distinct layers, low glaze glossiness, a good non-slip effect, an obvious sense of dry particles, a strong three-dimensional effect, rich colors, and stable properties.

Cement-based cementitious material and its formation method

A method for forming cement-based cementitious material includes: pouring a cement paste into a mold; applying an electrical current to the cement paste to perform an electro-osmotic reaction; and transferring the reacted cement paste into a water tank for curing, thereby obtaining a functionally graded cement-based cementitious material. A pair of electrodes is placed in the mold and connected to an external power source. The compressive strength of the functionally graded cement-based cementitious material in the middle is lower than that at either of both ends.

A method for manufacturing a honeycomb structure, includes: a step of manufacturing a honeycomb formed body to manufacture a non-fired honeycomb formed body having volume of 7 L or more; a drying step of drying the manufactured non-fired honeycomb formed body to obtain a honeycomb dried body; and a firing step of firing the obtained honeycomb dried body to obtain a honeycomb structure. The drying step includes: an induction drying step to obtain a first dried honeycomb formed body by removing 20 to 80% of the entire water that the non-fired honeycomb formed body contained before drying, and a microwave drying step to obtain a honeycomb dried body by removing the residual water. The honeycomb dried body subjected to this microwave drying step is obtained by removing 90% or more of the entire water that the non-fired honeycomb formed body contained before drying.

Ceramic slurries with photoreactive-photostable hybrid binders

Ceramic slurries may include ceramic particles, a photoreactive-photostable hybrid binder, and a photoinitiator. The photoreactive-photostable hybrid binder may include a photoreactive organic resin component, a photoreactive siloxane component, and one or more photostable siloxane components. Methods of forming a ceramic part may include curing a portion of a ceramic slurry by exposing the portion of the ceramic slurry to light to form a green ceramic part, and partially firing the green ceramic part to form a brown ceramic part. The brown ceramic part may be sintered at or above a sintering temperature of the ceramic particles to form a ceramic part, wherein sintering includes heating the brown ceramic part to a sufficient temperature to promote reaction bonding that converts silica from the photoreactive-photostable hybrid binder into silicates that bond with the ceramic particles.
