摘要： A process for the manufacture of a plasterboard including activated carbon, includes: preparing a main mixed batch including a foaming agent and devoid of activated carbon; preparing a secondary mixed batch including powdered activated carbon; providing a first facing sheet; pouring the secondary mixed batch over the first facing sheet, the secondary mixed batch forming a first plaster layer; pouring the main mixed batch over the first plaster layer, the main mixed batch forming a second plaster layer; providing a second facing sheet on the first and second plaster layers; and forming the plasterboard; wherein the secondary mixed batch has a greater density than the main mixed batch.

摘要： A plaster-based board includes a core made of plaster positioned between two coating layers, in which a textile including glass fibers and an organic binder constitutes at least one of the coating layers and/or the textile is embedded in the plaster constituting the core. In the textile, the binder includes one or more organic polymers having a glass transition temperature which varies from −10 to +25° C., measured by differential scanning calorimetry according to the standard ISO 11357-1:2009.

摘要： A plasterboard includes a first layer of plaster and a second layer of plaster, wherein the first layer includes activated carbon; the second layer includes a scavenging agent, wherein a content of scavenging agent in the first layer, expressed as percentage by weight of dry matter, is less than a content of scavenging agent in the second layer, and wherein the second layer is free of activated carbon.

摘要： A plaster-based board includes a plaster-based core positioned between two sheets of paper or nonwoven fabric, wherein the core contains at least one polymer selected from polyvinyl butyral (PVB), copolymers of vinyl acetate and an olefin, which copolymers have a glass transition temperature that varies from −10° C. to +25° C., terpolymers of vinyl acetate, an olefin and a vinyl ester monomer, terpolymers of vinyl acetate, a vinyl ester monomer and a (meth)acrylate monomer, and copolymers of vinyl acetate and an acrylic monomer.

摘要： A plaster-based material, in particular a plasterboard intended for the interior fitting of dwellings, contains a mixture of casein and active charcoal. The plaster-based material is used for reducing the amount of volatile organic compounds present in the atmosphere inside dwellings, offices or public buildings.

摘要： A plaster-based material, in particular a plasterboard intended for the interior fitting of dwellings, contains a metal complex of EDTA. The plaster-based material is used for reducing the amount of volatile organic compounds present in the atmosphere inside dwellings, offices or public buildings.
