The present invention relates to a health artificial pearl and a manufacturing method therefor and, more specifically, to: a health artificial pearl formed by spray-drying and pressure-firing a functional mineral that emits anions and radiates far infrared rays, so as to form a core with high compressive strength, and by coating the surface of the core with an artificial pearl composition, which is nontoxic to the human body; and a manufacturing method therefor. The method for manufacturing a health artificial pearl comprises: (S100) a material pretreatment step of wet-grinding a functional mineral that emits anions and radiates far infrared rays so as to form a wet-ground solution, and spray drying the wet-ground solution so as to prepare a powder for press forming; (S200) a press forming step of injecting, into a press forming apparatus, the powder for press forming so as to form a core, and high-temperature-firing the core; (S300) a core polishing step of polishing the high-temperature-fired core; and (S400) a coating step of coating the polished core with an artificial pearl composition.

A surface treatment composition including polymeric complex nanoparticles used in a hydrophobic agent and siloxane complex nanoparticles used in a suspending agent thereof. The composition of the present invention is a solution comprising a plurality of components. The primary components are an acid mixture and a base mixture that are combined together in a manner to be described herein to produce a two-part liquid solution. The two parts, are combined together prior to application to a surface and allowed to cure on the surface.

A method of producing a neutron absorbing plate constructed of a boron carbide aluminum matrix composite material is disclosed. The method includes mixing a 30-50 micron average particle size B4C powder with an aqueous organic binder component to form a slurry; then drying the slurry at a temperature from about 20 to about 90 degrees Celsius until a dried cake comprising 1-20 percent organic binder of the total weight of said dry cake is formed; then granulating said dried cake to yield a granule size from about 0.5 mm to about 3 mm; then compressing said granules under pressure to create a particulate preform having an interior open porosity; and finally infiltrating the preform under pressure with a liquid metal, to form a metal matrix composite with uniform B4C particle loading.

In the present disclosure, a method of forming a gypsum panel is disclosed. The method comprises: providing a first facing material, forming a starch slurry by combining starch and water at a shear rate of 3,000 rpm or more, providing the starch slurry onto the first facing material, depositing a gypsum slurry comprising stucco and water onto the starch slurry on the first facing material, providing a second facing material on the gypsum slurry, and allowing the stucco to convert to calcium sulfate dihydrate.

Disclosed herein are formulations comprising biologically prepared fibers and methods of preparing said formulations. These formulations can be utilized for repair of structures comprised of a variety of materials, including cementitious material, natural rock, mortar, and concrete. The formulation includes biologically prepared fibers, and a solvent or carrier solution. The formulation may additionally and optionally incorporate at least one enzyme. Once the formulation containing the biologically prepared fibers is applied to a void or crack within the structure, the fibers form a three-dimensional fibrous scaffold configuration in the void of the structure.

Ceramics are capable of reducing color irregularities and uneven coating, hard to dissolve into glaze, and excellent in fixation. A water-based paint contains a coloring material, first cellulose nanofibers having a lignin content of 20 to 40 mass % and a water retention of 150 to 300%, and second cellulose nanofibers having a higher viscosity compared to the first cellulose nanofibers, and the water-based paint has a B-type viscosity of 600 cps or higher. Ceramic ware or glassware or the like having painting made on a green body of which surface is formed of silicic acid or silicate compound as a main component, with the water-based paint.
