Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic glass production equipment, in particular to an ultra-white embossed photovoltaic glass calender. Background Art

[0002] Ultra-white embossed photovoltaic glass, also known as ultra-white calendered glass, is a type of photovoltaic glass mainly used for the encapsulation of solar cells. It is an essential component of solar photovoltaic cells and is widely used in fields such as flat plate collectors, glass curtain walls, solar houses, and decorative painted glass.

[0003] During the production of embossed photovoltaic glass, the calendering method is one of the most commonly used production methods. This method precisely controls the flow, friction, and stretching of high-temperature glass liquid between calender rolls to form a glass ribbon with specific patterns and thicknesses to meet the strict requirements of photovoltaic modules for light transmittance, mechanical strength, and aesthetics. Among them, the embossing roll, as a key device in the calendering process, the design and operation of its cooling system play a crucial role in the quality of the final product.

[0004] Due to the high-temperature operation involved in the calendering process, the surface temperature of the roll will rise sharply. If the roll temperature is too high, it will not only cause the phenomenon of sticking to the roll, resulting in the deformation of the glass ribbon during calendering and affecting the clarity of the surface pattern, but also may cause uneven thermal stress in the glass ribbon, increasing the probability of defects such as cracks and bubbles.
