what is eva photovoltaic film glass used for?

why use photovoltaic glass? generating electricity is the main use of photovoltaic glass. photovoltaic glass is a special type of glass that can use solar radiation to generate electricity and has associated current output devices and cables. the glass used in photovoltaic power generation glass is not ordinary glass, but tco conductive glass.

understand what photovoltaic glass can do, and then, let’s understand the photovoltaic glass production process. the production process of photovoltaic glass is mainly divided into two links: raw sheet production and deep processing.

raw sheet production is an unprocessed photovoltaic raw sheet semi-finished product, which undergoes five steps of mixing, melting, calendering, annealing, and cutting, and then undergoes deep processing.

the production of raw films includes five processes: batching section, melting section, forming section, annealing section and edge breaking section. melting, forming and annealing are the core steps of the raw film production line. problems in any link will affect product quality and productivity. the continuity of glass production is very continuous. finished photovoltaic glass with poor quality needs to be refurbished and rebuilt, which will bring additional costs to the manufacturing company. the normal production of original products is continuous operation 24 hours a day and cannot be stopped. if product quality is unstable, unstable production** is often performed.

the deep processing process of photovoltaic glass includes two processes: tempering and coating. the sheet is edged and then tempered to obtain a tempered sheet or tempered coating, which is used for component packaging. among them, tempering aims to increase the strength of the glass, and coating is to apply an anti-reflective film on the tempered glass to increase the light transmittance.

the tempering and coating process requires 700 yuan. in order to control costs, most glass deep processing companies use glass tempering and film heat treatment.

in the production process of photovoltaic glass, the furnace is not only the core production equipment, but also the equipment with the largest investment by the enterprise. it has two characteristics: the temperature of a large kiln furnace is difficult to control, the cost of starting and stopping the kiln furnace is high, and the production line cannot be shut down and adjusted midway.
