Abstract (en)

[origin: WO2011029852A1] The present invention relates to a method for manufacturing a bended glass sheet with a permanent glass sheet bending. The method (cold bending of a glass sheet) comprises following steps : a) Providing a tempered flat precursor glass sheet with a glass sheet thickness selected from the range between 2 mm and 10 mm; b) bending the tempered flat precursor glass sheet with the aid of an external bending force such, that a bended glass sheet with a glass sheet bending results; and c) fixing the glass sheet bending of the bended glass sheet such, that the permanent glass sheet bending results; wherein the bending the tempered flat precursor glass sheet is executed at a bending temperature which is selected from the range between 0°C and 70°C. In a preferred embodiment the bending temperature is selected from the range between 0°C and 50°C and particularly from the range between 0°C and 40°C. Moreover a manufacturing system for executing the method with is provided. The use of the method relates to the manufacturing of a bended mirror with a permanent mirror bending. For instance, a tempered glass sheet is coated with a multilayer stack with a reflecting layer containing Silver. This coated glass sheet is brought into the desired parabolic shape by the described bending process. In view of a solar field application it is advantageous that instead of 2 or 3 mirrors one "long" mirror can be used. This reduces the costs and improves the optical performance. The bended mirror or the assembly with the bended mirror is used as a sunlight concentrator.
