[0002] Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals as the main raw materials, and a small amount of auxiliary raw materials are added. Ultra-white glass panels are used in the field of photovoltaic power generation. Ultra-white glass is an ultra-transparent low-iron glass, also known as low-iron glass and high-transparency glass. It is a high-quality, multi-functional new high-end glass variety with a light transmittance of more than 91.5%. After the glass panel is cut into appropriate sizes, the original glass sheet is obtained. The original glass sheet can be packaged and sold directly, or it can be processed after fine processing. The fine processing of the original glass sheet includes the grinding operation of the glass corners.
