The present invention relates to the use of sacrificial agents to counteract the deleterious impact of gypsum contaminants on the effectiveness of certain stucco additives, particularly, water reducing agents and foaming agents, in a stucco slurry used to make gypsum wallboard.

The present invention relates to a process for the production of composite elements comprising a first and a second outer layer, a vacuum insulation panel between the two outer layers, rigid polyurethane foam in contact with the first outer layer and the underside of the vacuum insulation panel, and also rigid polyurethane foam in contact with the second outer layer and the upper side of the vacuum insulation panel, comprising application of a reaction mixture (R1) for the production of a rigid polyurethane foam onto the first outer layer, bringing the lower side of a vacuum insulation panel into contact with the unhardened reaction mixture (R1), application of a reaction mixture (R2) for the production of a rigid polyurethane foam to the upper side of the vacuum insulation panel, bringing the second outer layer into contact with the layer of the unhardened reaction mixture (R2), and finally hardening of the two rigid polyurethane foam systems (R1) and (R2) to give the composite element. The present invention further relates to composite elements thus obtainable, and also to the use of a composite element of the invention or of a composite element obtainable by a process of the invention, as component for refrigeration equipment or as construction material.

Method for manufacturing a plastic panel having a first side (1) with a hook (11), a first assembly cavity (12) and a locking cavity (13) which is recessed and whose upper side forms a bearing surface and a protrusion (21) comprising a beak (24) in the junction plane, an inset recess (23) continuing by a bearing point (32) connecting with a groove (31), a flexible lock (3) which can retract by elastic deformation into the recess (23) during the assembly movement of the panel (100a) to be installed and extend inside the locking cavity (13).

According to the method, the first side (1) is machined (I) to its final section and with the blank of the second side (2) with a protruding tab (4) which is locally heated (II) after cooling (III) to bend it and form the lock (3).

Provided are a structure and a method of forming a structure that includes a core made, at least in part, of a rice hull composition. The rice hull composition including a combination of separate, unground rice hulls; ground rice hulls; and a rice hull powder, that each have a different particle size. A polymeric binder, such as a recycled plastic polymeric binder binds the separated unground rice hulls, the ground rice hulls and the rice hull powder together.

This invention is an additively manufactured wall panel using computer aided design (CAD) and computer aided manufacturing (CAM) to design and manufacture multi-colored and multi-layered wall panels. This results in a variety of highly attractive, multi-colored wall panel faces ranging from brick, colored grout lines and multi-colored stones to multi-colored geometric designs. The design and manufacturing process greatly reduces the amount of precast cementitious materials by efficiently using higher quality materials. This reduces cost and weight while simultaneously producing a much more comprehensive, multi-functional wall panel complete with an interior frame, exterior insulation and an air, vapor and moisture barriers.

The disclosure relates to a method for producing an extruded sheet, which includes: a) providing calcium carbonate (CaCO.sub.3) powder; b) providing polyvinyl chloride (PVC) powder; c) providing additives as stabilisers, e) heating the mixture until the PVC softens to form a kneadable mass and the CaCO.sub.3 at least partially bonds to the PVC; f) cooling the mass; g) conveying the mass to an extruder; h) melting and extruding the mass by means of an extruder and moulding into a sheet by means of a slotted nozzle; i) pressing the still-warm sheet to a desired final thickness by means of at least two calendar rolls; and j) at least one layer of a pigmented lacquer is applied to the upper side; and k) an additional lacquer is applied to the pigmented lacquer to increase the scratch resistance.

A thermal insulation injection gun includes a pointed nozzle that prevents blocking of the nozzle by a distal panel of a building cavity and/or by pre-existing insulation within the cavity. In embodiments, the pointed nozzle can be pressed through a panel, thereby forming the injection hole. An enhancement port can be provided through which an enhancing material such as a carrier fluid, particulate or fibrous insulating material, a binder, or a fire retardant can be added and mixed with the insulating material. Embodiments include expanding nozzle wings that can compress pre-existing insulation to create a space on a proximal or distal side thereof for injecting the insulation. A compressible sheath installed over the nozzle can prevent dripping of excess insulation from the panel hole. Exchangeable collars can be used to fix an insertion depth of the nozzle and/or to block selected lateral dispensing ports of the nozzle.
