    摘要: A triaxial laid scrim includes a first, second and third set of continuous fibers. The fibers of each set are regularly spaced apart and are parallel to each other. The fibers of the first set are parallel to the warp direction or to the weft direction of the scrim. The fibers of the second set and the third set are oriented symmetrically to each other, respectively at an angle of 30°-80° with respect to the fibers of the first set. Distances between the fibers of the second set and the fibers of the third set are identical. The fibers of the second set cross the fibers of the third set at the intersection thereof with the fibers of the first set, thereby defining regular openings having an isosceles triangle shape. The fibers are coated and attached to each other by a coating that does not fill-up the triangle-shaped openings.

    摘要: Disclosed are a hollow pipe-sandwiching metal plate and applications thereof. The hollow pipe-sandwiching metal plate comprises a first panel, a second panel, and multiple hollow pipes between the first panel and the second panel; gaps are arranged among the hollow pipes, and the hollow pipes are connected to the first panel and the second panel by brazing. The present disclosure further includes the applications of the hollow pipe-sandwiching metal plate. The hollow pipe-sandwiching metal plate has advantages, such as light weight, high strength, low stress, high temperature resistance, pressure bearing, thermal insulation and vibration isolation. The metal plate will not deform due to thermal difference, thereby providing permanent service life of the metal plate.

    摘要: A building envelope, in particular a wall, a floor, or a roof of a building with at least two shells spaced some distance apart from one another, which encloses an intermediate space, said space being essentially empty with the exception of weight-bearing and/or construction-engineering elements or being filled at least in sections with porous, open-celled material and sealed from the interior and exterior of the building, wherein controllable sealing means are provided for sealing the intermediate space from the interior and exterior and optionally separated building envelope sections from one other.

    摘要: The problem addressed by the invention is that of producing aerogels which have as high and permanent a hydrophobicity as possible and which have a reduced combustibility, that is as low a carbon content as possible, and are simultaneously less rigid and brittle than known systems, i.e. which with reduced combustibility have a high flexibility and high stability at the same time, that is high mechanical load-bearing capacity. Said problem is solved in that the invention provides gels chosen from lyogel or aerogel, which are synthesised from oxide units and [RxSiO(4-x)/2] units, wherein the primary particles have a change of concentration in [RxSiO(4-x)/2] units from the inside to the outside, wherein x can be the same or different and is 1 or 2, and R can be the same or different and is hydrogen or an organic substituted or unsubstituted radical, and wherein the oxide units contain [SiO4/2] units, and a method for producing same. The gels provided can be used in cosmetic, medical or for chromatographic applications, and as a catalyst or catalyst support. If the gels are aerogels, same are preferably used for thermal and/or acoustic insulation.

    摘要: A retrofitting appliqué for stepped application to a building wall construction. For external retrofitting, the system has an air barrier layer impermeable or semi-permeable for moisture, a ventilated air cavity used to modify temperature and/or remove water that may be coming from both sides or to modify the relative humidity of the ventilation air, a layer of thermal insulation, a composite material called Eco-Wrap with capillary active capability, in which a hydronic heating or cooling system may be located, and a surface finishing layer. For internal retrofitting, the system has an air barrier system arranged onto the wall of the building and separated from a layer of permeable or semi-permeable thermal insulation by a ventilated air gap. The layer of insulation, in turn, is in contact with a layer of Eco-Wrap. A permeable interior finishing layer that may also have capillary active performance is in contact with the Eco-Wrap. Methods for installing the retrofitting appliqué are also disclosed.
