The present invention relates to a roofing tile, a roofing shingle or facade element having a photovoltaic solar element and a method for producing such a roofing tile/roofing shingle/facade element.
摘要:
The solar module according to the invention consists of a transparent adhesive layer (1), in which the solar cells (3) that are interconnected by cell connectors (2) are embedded. A transparent, UV stable, thin front layer (4), composed for example of a thin pane of glass, is located above said adhesive layer. The supporting sandwich element (5), consisting of a nucleic layer (6) and glass fibre layers (7) bonded by means of polyurethane is located on the rear face. Fastening elements (8) and an electric socket (9) are integrated into the supporting sandwich element. A barrier film (10), which prevents the entry of water and oxygen, adjoins the sandwich element. The solar module has peripheral edge protection (11) consisting of elastomeric polyurethane, which prevents the lateral penetration of water, dirt and oxygen. The invention also relates to a method for producing the solar module.

摘要:
The invention relates to an installation and to a process for the production of foam in a continuous foaming process with the following steps,measuring actual surface temperatures of the foam or the facing layers along a conveying direction anddetermining a control variable for the foaming process as a function of a deviation of the actual surface temperatures from the nominal surface temperatures.
摘要:
The invention describes a device for determining the gas content of a liquid. The device has at least a housing, a measuring chamber base with a cavity and a measuring chamber cover inside the housing. The measuring chamber base and the measuring chamber cover are each movable by a respective piston independently of one another along the longitudinal axis of the housing. The measuring chamber base and the measuring chamber cover form a measuring chamber in the housing. The measuring chamber base or the measuring chamber cover is connected to a pressure sensor and the housing has a liquid inlet and a liquid outlet.
