Curved mirror reflector and production method thereof

Abstract

The invention provides a curved mirror reflector (2), which comprises a flat glass structure (6), a middle bonding layer (7) and a flat glass mirror (8), wherein the flat glass structure (6) and the flat glass mirror (8) are processed by non-edging and / or non-tempered common glass; the middle bonding layer (7) is located between the flat glass structure (6) and the flat glass mirror (8), and is bent and deformed under support of a mould through a mechanical manner, and the bent and deformed flat glass structure (6), the middle bonding layer (7) and the flat glass mirror (8) are solidified and bonded to a composite curved surface structure through a heating and / or normal-temperature solidification manner. The curved mirror reflector (2), provided by the invention, can be widely applied in all kinds of fields of solar thermal collection and focus and solar thermal power generation.

Description

technical field [0001] The invention relates to the field of glass products and processing, in particular to a curved reflector applied in the field of solar energy and a manufacturing method thereof. Background technique [0002] At present, in many industrial installations, especially in solar concentrating systems, concentrating mirrors of various shapes are often used. Concentrating mirrors mainly include trough parabolic mirrors, curved parabolic mirrors, curved spherical mirrors, etc.; and micro-curvature heliostat concentrating mirrors or zero-curvature plane mirrors in the tower power generation mirror field. [0003] Typically, curved mirrors are obtained by deforming flat mirrors or flat glass. There are two types of forming processes for curved mirrors: one is the high-temperature thermal deformation manufacturing method, and the other is the mechanical cold deformation manufacturing method. [0004] The high-temperature thermal deformation manufacturing method ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the advantages that the curved reflector made of toughened glass has high strength, strong wind and hail resistance, and the toughened glass is broken into obtuse corner particles that will not harm people, but it also has the disadvantages of its own structure. Edge grinding is difficult, the cost of tempering is high, and the chemical tempering process pollutes the environment, while the high temperature of the physical tempering process causes wind spot deformation and affects the accuracy of the mirror; moreover, local sharp impacts can quickly cause micro-cracks to expand rapidly
