The invention relates to the field of building ceramic materials, and specifically discloses a soft light super-wear-resistant diamond glaze, a ceramic tile and a preparation method thereof. The main raw materials of the super-wear-resistant diamond glaze in parts by weight are as follows: 30-70 parts of a frit, 20-55 parts of an aggregate, 0.1-6 parts of an additive, 30-50 parts of water; the frit contains Al.sub.2O.sub.3≤10%, Na.sub.2O+K.sub.2O≤3%. Correspondingly, the present invention also discloses a super-wear-resistant diamond glazed ceramic tile and a preparation method thereof. The diamond glaze disclosed in present invention has the characteristics of excellent transparency, good wear resistance and stain resistance and almost has no air bubbles.

A blank material for a ceramic tile consists of the following components in percentage by weight: nepheline powder: 10%-15%; clay with a carbon content of ≥3.0 wt %: 10%-15%; clay with a carbon content of ≤0.5 wt %: 15%-22%; clay with a carbon content between 0.5 wt % and 3.0 wt %: 10%-15%; recycled waste blank: 5%-10%; sodium potassium powder: 5%-10%; sodium feldspar powder: 12%-20%; desulfurization residue: 0%-7%; waste from edging and polishing: 15%-26%; waste porcelain powder: 5%-10%; liquid gel remover: 0.3%-1.0%; liquid reinforcing agent: 0.2%-0.8%. Its preparation method comprises the following steps: preparing raw materials for a blank body and ball milling, powder spray granulation, aging, pressing and molding of the blank body, drying, polishing the blank body, spraying water, glazing, applying a decorative pattern, firing.

Some implementations herein described improvements to concrete products and processes for producing concrete products that may provide a positive environmental impact and that can be stronger relative to the percent of cement used. Particular examples include improvements to zero-slump to near-zero-slump concrete mixture design, material storage and handling, batching, mixing, sequencing and curing processes, as well as forming and curing techniques.

An inkjet printhead, a system including an inject printhead, and a method for applying primer to a target area on an outer surface of a ceramic body. The inkjet printhead comprises an ink chamber comprising the primer therein. The primer comprises a pigment, a binder, and a solvent. The primer also comprises a surface tension of at least about 40 mN/m. A spray nozzle is connected to the ink chamber and comprises an exit opening that comprises an area of less than about 20,000 square microns. The spray nozzle is configured to eject droplets of the primer from the exit opening at an average exit velocity of less than about 4 m/s.
