摘要： The present disclosure describes three-dimensional printing kits, systems for three-dimensional printing, and methods of three-dimensional printing. In one example, a three-dimensional printing kit can include a particulate build material and a binding agent. The particulate build material can include metal particles. The binding agent can include a polyhydroxy polyol and a water-dispersible blocked polyisocyanate having multiple blocked isocyanate groups. The blocked isocyanate groups can include a blocking group bonded to the carbon atom of the blocked isocyanate group through a labile bond breakable by heating to a deblocking temperature. Breaking the labile bond can produce a released blocking group reacted with hydrogen and an isocyanate group.

摘要： The present invention provides a fast-curing molding process for epoxy resin. The method includes the following steps: S1, mixing epoxy resin A glue and a protein-grafted manganese-zinc-iron oxide nanomaterial well into a colloidal state, and grounding the mixture for 10 to 30 min; S2, adding epoxy resin B glue to the mixed colloid in S1, and performing ultrasonic dispersion at 20 to 30° C. for 10 to 30 min; and S3, placing the mixture obtained after ultrasonic dispersion in S2 in a vacuum environment for 20 to 40 min, then taking the mixture out and injecting the mixture into a mold, placing the mold and the mixed colloid into an electromagnetic induction heater, placing the electromagnetic induction heater in a magnetic field environment with a magnetic field intensity of 1 to 1.5 mT for 2 to 3 h, cooling and then taking them out to obtain the cured epoxy resin.

摘要： Exemplary methods for installing tile using a reactivatable tile bonding mat is disclosed. The reactivatable tile bonding mat is placed upon a substantially flat surface. Stone, porcelain or ceramic tile is placed and arranged on the reactivatable tile bonding mat in an aesthetically pleasing fashion, in some cases aided by the use of spacers in the joints between the sides of the tiles. Induction, or some other method of heat, is applied to the upper surfaces of the tiles, to quickly transfer through the tile, causing a polymer hot-melt material embedded in the reactivatable tile bonding mat to melt and adhere to a lower surface of the tiles, forming a strong bond. Upon the tiles fully bonding to the reactivatable tile bonding mat, spacers may be removed and a suitable grout may be applied in the joints between the sides of the tiles.

摘要： A method for the production of a glassy metal polymer composite is disclosed. The method comprises adding a polymer and a metal to an extruder, wherein the extruder is heated to an extrusion temperature greater than the melting point of the polymer and the melting point of the metal; mixing the metal and the polymer in the extruder for a predefined residence time; and co-extruding the composite from the extruder.
