Abstract: Apparatus for continuously preparing a homogeneous solution (28) of powder in liquid including a mixing chamber (16) into which a liquid solvent (14) is introduced via an inlet pipe, and into which a solid solute (12) is fed via a dosing unit, an agitator (26) operative to mix the solid solute with the liquid solvent so that the solid solute dissolves in the liquid solvent to form a homogeneous solution, and a fluid dynamic separator (34) placed within a flow of the solute (12) and the solvent (14) in the chamber (16), the fluid dynamic separator (34) operative to create a region (38) isolated from the rest of the flow in the chamber and to cause solid particles of the solute that have not yet dissolved in the solvent to flow away from the region so that the region contains the homogeneous solution of the solute dissolved in the solvent.

Abstract: A method of manufacturing a wood product including using a water and wax mixture with wood particles in a production process of wood products, wherein the wax mixture includes a hydrocarbon wax, and a water-repellant material selected from the group consisting of (a) an asphaltite, (b) a polyolefin copolymer, (c) a polyolefin synthetic wax, and (d) combinations thereof, and forming a wood product.

Abstract: A method of manufacturing a water-resistant gypsum product including forming an aqueous mixture of gypsum, water and a wax mixture, wherein the wax mixture includes a hydrocarbon wax, and a substitute material selected from the group consisting of (a) an asphaltite, (b) a polyolefin homopolymer, (c) a polyolefin copolymer, and (d) combinations thereof; and forming the mixture into a structure, and drying the structure while permitting hydration of the gypsum to form a gypsum product.
