CERAMIC HONEYCOMB BODIES HAVING HIGH-STRENGTH SKIN AND MANUFACTURING METHODS THEREOF

Methods of manufacturing a ceramic honeycomb body having a honeycomb structure with a matrix of intersecting walls, and a skin disposed on an outer peripheral portion of the matrix where the skin has a first average porosity and the interior portion of the matrix has a second average porosity that is greater than the first average porosity. The methods include coating at least the skin with a fluid formulation containing a sintering aid and subsequently firing the honeycomb structure. In certain embodiments, a glass layer is formed in the skin or in regions of the walls directly adjacent to the skin. In certain embodiments, the coating is applied to a green honeycomb structure, and in other embodiments the coating is applied to a ceramic honeycomb structure. Other honeycomb bodies and methods are described.

Compositions and methods for curing concrete

A composition that may be used to retain moisture within fresh concrete as it cures to optimize the curing of the concrete may include one or more hardening and densifying agents (e.g., alkali metal polysilicate, colloidal silica, etc.) and one or more temporary moisture sealing agents (e.g., a wax, etc.). Additionally, such a composition may include a siliconate (e.g., a metal siliconate, such as an alkali metal siliconate like potassium methyl siliconate, etc.). The hardening and densifying agent of such a composition may penetrate the surface of fresh concrete to react with free lime, providing the fresh concrete with a strong surface. The temporary moisture sealing agent may form a moisture barrier on the surface of the fresh concrete to prevent moisture from escaping from the fresh concrete (e.g., evaporating, etc.) before the fresh concrete has sufficiently cured. The temporary moisture sealing agent may degrade within a matter of days (e.g., three days, seven days, 14 days, less than a month, etc.), facilitating its removal from the surface of the concrete once the concrete has cured and enabling further treatment of the surface without undue delay.

METHOD FOR MANUFACTURING CERAMIC TILES DECORATED WITH DRY PARTICLE INKS

The present disclosure relates to the field of ceramic tiles, in particular, to a ceramic tile decorated with a dry particle ink and a manufacturing method thereof. The manufacturing method comprises the steps of A: decorating a ground coat; B: decorating to form a pattern; C: drying firstly; D: embellishing with dry particles; E: spraying a protective glaze; and F: firing. The manufacturing method has simple operation steps and convenient control, simplifies the process flow, improves production efficiency, and reduces production difficulty and production cost. By spraying with the dry particle ink, jet printing is carried out on a designated position on the surface of a green body, so that the texture sprayed can accurately correspond to the pattern-decorated texture, and the uniformity and adhesion of the dry particle distribution on the surface of the green body can be improved.
