摘要:
The present description relates to method of initiating the curing of carboxylic acid-treated material compositions to enable an initial lowering of the viscosity and stiffness of the material for low temperature wetting and coating of solid surfaces, for paving, for waterproofing, for roofing, and for underlayment applications. The present description relates to ecologically sound, non-toxic technology that enables a practitioner to improve the low-temperature cracking properties of a material or material composition while also inducing a rapid increase in the high-temperature stiffness and viscosity of the material or material composition, and to rapid cure and strength development of finished product composition for application in paving, roofing, adhesive interlayer bonding, roll finishing, blow-molding, water-proofing, and underlayment.

Die vorliegende Erfindung betrifft Beschichtungsmassen, umfassend mindestens 9 Gew.-%, an Feststoffanteil, bezogen auf das Gesamtgewicht der Beschichtungsmasse, mindestens eines organischen Bindemittels, mindestens ein Hydrophobierungsmittel, mindestens 20 Gew.-%, bezogen auf das Gesamtgewicht der Beschichtungsmasse, mindestens eines ersten Füllstoffs, wobei der erste Füllstoff einen D50-Wert von mindestens 10 µm aufweist, gegebenenfalls mindestens ein Additiv, und Wasser, wobei die Anteile der die Beschichtungsmasse bildenden Komponenten jeweils 100 Gew.-% ergeben. Ferner betrifft die Erfindung eine Beschichtung erhalten oder erhältlich durch Applizieren der erfindungsgemäßen Beschichtungsmasse auf einer beschichtbaren Oberfläche und Trocknen der applizierten Beschichtungsmasse. Außerdem betrifft die Erfindung ein Bauteil, insbesondere eine Wand oder eine Decke, enthaltend auf einer beschichtbaren Oberfläche eine erfindungsgemäße Beschichtung. Schließlich betrifft die Erfindung ein Verfahren zur Herstellung einer erfindungsgemäßen Beschichtung sowie die Verwendung der erfindungsgemäßen Beschichtungsmasse für die, insbesondere einstufige, Herstellung von, insbesondere selbstnivellierenden und/oder oberflächenfertigen und/oder glatten, Wand- und/oder Deckenbeschichtungen.

Some embodiments provide methods and systems for casting articles. One example of a method includes providing and positioning a thermal blanket within a mold cavity and then introducing a molten material into the mold cavity and into contact with the thermal blanket. The method allows the molten material to remain in a molten state during a dwell time that extends from the introduction of the molten material at least until the mold cavity is filled. In another example, a method of using a thermal blanket includes keeping a molten material in a molten state during a dwell time extending from first introduction of the molten material until pressurization. Systems including a variety of mold types, one or more thermal blankets, and in some cases preforms and/or inserts are also provided. Also described is a novel thermal blanket and method of manufacturing the same.

摘要:
Disclosed are formulations adapted to form a foamed cementitious composition, the foamed cementitious composition itself, a method of forming a hydraulic binder foam, and a method of conveying and applying the resulting foam to a substrate. A pumpable cementitious slurry is formed, the slurry is mixed with a gas such as air, and is subjected to mechanically created turbulence to generate gas bubbles and create a foam, which preferably is stabilized by a foam stabilizing agent such as polyvinyl alcohol present in the slurry. The foam is then conveyed to a nozzle or other suitable dispense point from which it is applied, for example sprayed, preferably uniformly, onto a substrate to be coated. Prior to dispensing, a set accelerator is preferably injected, which causes the foam to gel, which in turn improves the hangability of the product on a substrate. The spray material adheres to the substrate and hardens to form an insulative coating on the substrate. Also disclosed are dry compositions comprising a hydratable cementitious binder, a mechanical foam stabilizing agent, and optionally a fibrous component, set retarder and air entraining agent, said composition providing, on the addition of water, gas and mechanical turbulence, a settable foam which is capable of spray application to a steel structural member and which, after spray application, is adherent to the member in the foamed state and after setting. The foam after setting, forms a fire and heat protective adherent coating on the member.
