Изобретение относится к способу получения блочной стеклокристаллической пенокерамики. Техническим результатом изобретения является изготовление пенокерамических материалов толщиной до 200 мм с равномерно замкнутой мелкопористой структурой по всему объему материала и высокими физико-химическими свойствами. Способ включает подготовку тонкомолотой стеклокристаллической фазы с размером частиц 1-50 мкм, содержащей отходы производства с содержанием не менее 10 мас.% карбида кремния. Затем проводят подготовку тонкомолотой шихты для изготовления пеноблоков, имеющей размер частиц 1-50 мкм и содержащей тонкомолотую стеклокристаллическую фазу в количестве 5-95 мае. % и связующий компонент. Из шихты прессуют заготовки в виде крупноразмерных плиток, сушат до остаточной влажности 0,5%, осуществляют обмазку двухслойным ангобом нижних и боковых поверхностей, параллельных движению роликового транспортера. Высушенные плитки по роликовому транспортеру поступают в печь обжига, где в конце зоны спекания скорость транспортера меньше на 10-25%, чем до нее. После вспенивания брус подвергают резкому охлаждению, наносят надрез и после выхода осуществляют разделение на блоки по линиям надреза с последующим отжигом и механической обработкой.
Abstract:
The invention relates to stable molded bodies and plates which are used as a lightweight material for equipping building envelopes with thermal insulation or as a local fire-protection measure. The stable molded bodies and plates are produced on the basis of expanded perlite, from a homogeneous mixture, which then hardens. Specifically, such a plate is composed of a prepared homogeneous mixture, having a composition of at least 40% by volume of glazed balls made from expanded silica sands, which balls are closed-cell at the surface thereof and are filled with air. The balls have a density of only 50 to 400 grams/liter, such that normally no measures for hydrophobing are necessary because of the closed-cell, unfractured perlite. The remaining volume consists of a mineral or organic binding agent, which was prepared and to which a foaming agent was added during the preparation thereof, such that the plate as a whole has a density between 120 kg/m3 and 1200 kg/m3, depending on the specific composition of all components, because of the air in the expanded perlite and the air from the foaming agent. Embodied as insulating plates, the plates are used to create wall structures on the inside or outside of buildings, in that the insulating plates (8) are applied to a cleaned interior or exterior wall of a building that has been leveled with a plaster and that afterwards has been provided with adhesive mortar. If necessary, the plates can be mechanically fastened to the building wall and afterwards a base coat (9) having a glass-based reinforcing woven-fabric mesh (10) can be applied, and finally a final coat can be applied, which is optionally provided with a coat of paint.
Abstract:
Die Mörtelmischung kann in Form einer Verputzmischung als Dämmputz ausgeführt werden, zum Isolieren von Gebäudehüllen und sie kann auch als Oberputz ausgeführt werden. Die Mörtelmischung kann jedoch für horizontale Flächen eingesetzt oder als Giessmörtel in Formen auch Pressformen verwendet werden. Die Mörtelmischung besteht in Bezug auf ihr Volumen im Minimum zu 20 % aus glasierten und somit an ihrer Oberfläche geschlossenen, mit Luft gefüllten Kugeln aus expandiertem Silicasand bzw. geblähtem Perlit. Diese Perlit-Kugeln sind versetzt mit Bindemitteln, Zusatzstoffen als Binder, einem Luftporenbilder und/oder weiteren chemischen Zusatzmitteln als Verflüssiger, Schnellbinder und aus Polymeren. Das Verfahren zur Herstellung der Mörtelmischung geht so, dass Perlitsand zunächst mittels einer Sieblinie in verschiedene Korngrösse sortiert wird. Jede einzelne Korngrösse wird anschliessend in einem Rieselkanal mit mehrstufigen Temperaturzonen aufgebläht, damit die Oberfläche der Kugeln verglast wird. Solchermassen erzeugter, glasierter geblähter Perlit wird durch Zugabe von Bindemitteln sowie Zellulose, Luftporenbilder und/oder chemischen Zusatzmitteln zu einem homogenen Gemisch zusammengemischt. Die Mörtelmischung wird zum Isolieren von Aussen- oder Innenwänden oder Böden von Bauwerken verwendet. Dazu wird sie mittels einer Schneckenpumpe mit Schnecke (1) und elastisch nachgiebigem und von aussen im Bereich der Schnecke (1) mit Luftdruck oder Öldruck beaufschlagbarem Pumpenzylinder (3), der in einem druckfesten Aussenrohr (4) untergebracht ist, über einen Schlauch (7) und durch eine Düse (10) mit oder Zugabe von Wasser auf eine zu isolierende Wand gespritzt. In der Anwendung der Mörtelmischung als Oberputz wird eine wässerige Dispersion als Bindemittel verwendet.

Abstract:
The current application discloses methods and systems for generating high pressure dual phase mixture. In some embodiments, the methods and systems involve mounting a dual phase mixture generator on a transportable platform wherein the dual phase mixture generator comprises a mixing chamber connected with at least a first inlet, a second inlet, and a first outlet. A first container and a first pump are also mounted on the transportable platform wherein the first pump is operably connected with the first container. The transportable platform and the mounted equipments are then deployed at a wellsite. A base fluid is pumped into the first inlet under high pressure, and a gas is pumped into the second inlet under high pressure. The base fluid and the gas is combined in the mixing chamber to generate a high pressure dual phase mixture, which is then discharged via the outlet.
