Abstract

The application belongs to the technical field of making solar glass panels, and in particular relates to a method for preparing solar glass panels, comprising the following steps: firstly providing a glass substrate; then performing silk screen or coating treatment on the surface of the glass substrate; finally putting the glass substrate into a Tempering treatment is carried out in the furnace to obtain solar glass panels; the heating time of the tempering furnace is 110s to 120s, the gap between two adjacent conveying rollers in the heating section of the tempering furnace is less than or equal to 15mm, and the cooling section of the tempering furnace is transported The radial runout value of the roller is less than or equal to 0.02mm. In the method for preparing solar glass panels, the heating time of the glass substrate is relatively reduced, which prevents the ultra-thin glass substrate from being excessively softened to cause a furnace phenomenon. In addition, the gap between the conveying rollers is small, and the stability of glass substrate transportation is good, ensuring that the glass substrate has Good flatness, at the same time, the radial runout value of the conveying roller is small, ensuring flatness and curvature.

Description

technical field [0001] The application belongs to the technical field of making solar glass panels, and in particular relates to a method for preparing solar glass panels. Background technique [0002] The development of solar photovoltaic power generation technology is rapid, and grid parity promotes the continuous technological progress of the entire industry. The development trend of the industry is that the demand for ultra-thin solar modules with high efficiency, light weight and low electricity cost is increasing, and higher requirements are put forward for the upstream and downstream materials of solar modules. [0003] However, most of the current solar modules use glass substrates with a thickness of 2.5mm, and thinner glass substrates are rarely used. The main reason is that the glass substrate is too thin, which will cause fragments and unstable product performance during the tempering process. Phenomenon, a little carelessness will lead to tempering furnace furn...
