20140319418 | PROCESS FOR PRODUCING HYDROGELS - The invention relates to a process for producing a hydrogel, which is performed in a reactor which has a body A which rotates about an axis of rotation and a metering system. A component comprising at least i) a soluble salt of an acidic or amphoteric oxygen-containing molecular anion and ii) a component comprising a precipitant are applied with the aid of the metering system to the surface of the rotating body A, such that a mixture of components i) and ii) flows over the surface of the rotating body A to an outer region of the surface of the rotating body A, the mixture leaves the surface and the pH of the mixture after leaving the surface of the body A is between 2 and 12. Additionally disclosed is the use of the resulting hydrogels for production of aerogels. | 10-30-2014 |

20150285027 | POLYUREA SILICATE RESIN FOR WELLBORE APPLICATION - Described herein is a novel method of strengthening a wellbore wherein the method uses a polyurea silicate composition. In the method of strengthening an oil well, a gas well or a water well, a mixture comprising at least one isocyanate component having at least two isocyanate groups per molecule; at least one alkali metal silicate; and water is pumped through the oil well, the gas well or the water well into the annulus of the well; subsequently, the mixture is allowed to form a polyurea silicate composition; before the polyurea silicate composition sets to thereby give a polyurea matrix comprising domains of silicate. | 10-08-2015 |
