Abstract:
Placa de revestimento em material cerâmico para a aplicação exterior, método de obtenção e respetivas utilizações. A placa de revestimento cerâmica para aplicação no exterior compreende uma camada vítrea em que a camada vítrea compreende 3-30 % (m/m) de um pigmento refletor infravermelho, em que o pigmento refletor infravermelho compreende dióxido de titânio - TiO 2 . A referida placa garante ao utilizador conforto térmico no contacto entre a superfície plantar dos pés e o material cerâmico e pode ainda ser usada no revestimento de fachadas, ou coberturas. A concentração de TiO 2 pode ser 5-25 % (m/m), 8-20 % (m/m), ou 9-11 % (m/m). As partículas de TiO 2 têm 0,1-2 µm, mais preferencialmente 0,25-2 µm. O pigmento refletor infravermelho pode compreender ainda os óxidos metálicos Al 2 O 3 , SiO 2 , MnO, SbO, Fe 2 O 3 , ou suas misturas. A referida placa pode ser um azulejo, um cerâmico, um mosaico, uma baldosa ou um ladrilho, entre outros.

Abstract:
Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. These waterproof gypsum panels have many uses, such as, tile backer board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, interior wall and ceiling, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, preferably silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives. Preferably a pre-coated non-woven glass fiber mat is employed to provide the inorganic mineral fibers for the surface reinforcement.
Abstract:
A method of depositing abradable coating on an engine component (10) is provided wherein the engine component is formed of ceramic matrix composite (CMC) and one or more layers, including at least one environmental barrier coating (14), may be disposed on the outer layer of the CMC. An outermost layer of the structure may further comprise a porous abradable layer (30, 130) that is disposed on the environmental barrier coating and provides a breakable structure which inhibits blade damage. The abradable layer may be gel-cast on the component and sintered or may be direct written by extrusion process and subsequently sintered.
