The ceramic powder material injection device is adapted to contain a ceramic powder material. The supercritical fluid providing device is adapted to provide a supercritical fluid to the ceramic powder material injection device. The mold has a molding concavity, wherein the ceramic powder material injection device is adapted to mix the ceramic powder material and the supercritical fluid to form a mixed material and inject the mixed material into the molding concavity. In addition, an injection molding method is also provided.

A system and method for applying a construction material is provided. The method may include mixing blast furnace slag material, geopolymer material, alkali-based powder, and sand at a batching and mixing device to generate a non-Portland cement-based material. The method may also include transporting the non-Portland cement-based material from the mixing device, through a conduit to a nozzle and combining the transported non-Portland cement-based material with liquid at the nozzle to generate a partially liquefied non-Portland cement-based material. The method may further include pneumatically applying the partially liquefied non-Portland cement-based material to a surface.

A system and method for applying a construction material is provided. The system may include a batching and mixing device configured to mix blast furnace slag material, geopolymer material, alkali-based powder, and sand to generate a non-Portland cement-based material, the non-Portland cement-based material including 4% to 45% geopolymer material by weight; greater than 0% to 40% blast furnace slag material by weight, 10% to 45% alkali by weight, 20% to 90% sand by weight, less than 1% sulfate by weight, and/or no more than 5% calcium oxide by weight; a conduit configured to transport the non-Portland cement-based material from the batching and mixing device; and a nozzle configured to receive the non-Portland cement-based material and combine the transported non-Portland cement-based material with liquid to generate a partially liquefied non-Portland cement-based material, wherein the nozzle is further configured to pneumatically apply the partially liquefied non-Portland cement-based material to a surface.

A system and method for applying a construction material is provided. The method may include mixing one or more of 4%-45% volcanic rock by weight, greater than 0%-40% latent hydraulic material by weight, 10%-45% alkaline component by weight, and 20%-90% aggregate by weight to produce a dry binding agent mixture, using a dry mixer; and combining the dry binding agent mixture with water at a nozzle to produce a sprayable concrete compound.

A system and method for introducing a slurry mixture for making gypsum board is disclosed. The system includes, for example, a mixer, a foam injector, and a canister for mixing and moving a slurry mixture of foam and gypsum slurry. Also included in the system is an apparatus having a funnel body constructed and arranged to further mix the slurry mixture. The funnel body includes a number of baffles projecting from its inner wall towards a center and that are spaced around the inner wall. The baffles induce turbulence into the slurry mixture as the slurry mixture moves towards its outlet, thus further mixing the mixture and reducing the flow rate of the slurry mixture before its exits from the outlet for depositing onto paper to form the gypsum board.

A microfluidic printing nozzle for 3D printing may include a mixing chamber, a first inlet for connecting with a first ink source, the first inlet located at a first end of the mixing chamber, and a second inlet for connecting with a second ink source, the second inlet located at the first end of the mixing chamber. An outlet may be located at a second end of the mixing chamber, and a generally cylindrical impeller may be rotatably disposed in the mixing chamber between the first end and the second end. The cylindrical impeller may include an outer surface, and the outer surface of the impeller includes a groove, a protrusion, or both, to facilitate mixing of fluidic inks flowing from the first end to the second end of the mixing chamber.

By homogeneously mixing a plurality of fluids, when mixing a gas with a liquid, it is possible to mix a large amount of gas into the liquid, so that large bubbles are not generated, and fine bubbles (in some cases, fine bubbles including microbubbles or ultra-fine bubbles) can be mixed into the liquid. A fluid mixing output apparatus of the present disclosure includes a housing and an internal structure accommodated in the housing. The housing is provided with a plurality of fluid supply ports for supplying at least a first fluid and a second fluid and a fluid outlet at its downstream end for outputting a plurality of fluids after mixing the plurality of fluids. The internal structure includes a first portion, a second portion, a third portion, and a fourth portion. The first portion includes a shaft portion and a vane spirally formed to generate a swirling flow in a fluid. The second portion is located downstream from the first portion, and includes a shaft portion and a plurality of protrusions protruding from an outer circumferential surface of the shaft portion. The third portion is located downstream from the second portion, and includes a shaft portion and a vane spirally formed to generate a swirling flow in a fluid. The fourth portion is located downstream from the third portion, and includes a shaft portion and a plurality of protrusions protruding from an outer circumferential surface of the shaft portion. One of the plurality of fluid supply ports of the housing is formed in a portion corresponding to the vane of the third portion, and the second fluid is supplied to the third portion and supplied to the fourth portion as a swirling flow while being mixed with the first fluid.
