Abstract: La présente invention a pour objet une combinaison d'un dispersant et d'un agent moussant utile à la production de panneaux de placoplâtre et d'autres produits cimentaires aqueux, une méthode de fabrication d'un panneau de placoplâtre et un panneau de placoplâtre. Le dispersant employé dans la combinaison de la présente invention est un polymère de sel alcalin de condensat naphtalène-sulfonate/aldéhyde ayant une masse moléculaire moyenne pondérée d'environ 17 000 à environ 47 000. De préférence, l'alcali est un métal alcalin ou un métal alcalino-terreux. De préférence, l'aldéhyde est le formaldéhyde. L'agent moussant utilisé dans la combinaison de la présente invention est un savon, de préférence un sel alcalin d'un éthersulfate d'alkyle et/ou d'un sulfate d'alkyle. La combinaison d'un dispersant de masse moléculaire élevée et d'un agent moussant produit un effet sur l'âme du panneau se traduisant par un plus grand entraînement de l'air (c.-à-d. la création de vides) et abaissant de la sorte le poids total du panneau sans nuire à sa résistance. Un panneau de placoplâtre fabriqué avec la combinaison de dispersant et d'agent moussant de la présente invention offre une meilleure résistance à l'arrachement des clous que les panneaux de placoplâtre fabriqué à partir d'un dispersant et d'un agent moussant classiques avec le même rapport de charges de solides.

Abstract: The present invention relates to methods and devices for providing microbial control and/or disinfection/remediation of an environment. The methods generally comprise: generating a Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of, e.g., hydration, ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to provide microbial control and/or disinfection/remediation in the environment, preferably both on surfaces and in the air. The vaporous hydrogen peroxide is generated from oxygen and water of the ambient air. Further, a diffuser apparatus for producing PHPG is disclosed, the latter comprising a source of ultraviolet light; a metal or metal oxide photo catalyst (e.g. TiO2), catalyst substrate structure; and an air distribution mechanism, wherein the morphology of the catalyst on its substrate is a thin, sail-like air-permeable structure, situated perpendicular to air flow through the diffuser apparatus; and wherein said morphology is supposed to alter the reaction equilibrium of the catalyst such that it produces hydrogen peroxide from both the oxidation of water and from the reduction of dioxygen.
