PVB Solar Film Production Machine Use Twin Screw Extruder For BIPV Modules

1. Machine model of SGP solar Film production machine

At present, the packaging forms of photovoltaic modules mainly include glass-EVA-backsheet and glass-PVB-glass. I will describe the characteristics of EVA and PVB encapsulation films respectively.

Photovoltaic industry is a rapidly developing emerging industry that converts solar energy into electric energy. Silicon solar cell modules are mainly used in large-scale grid-connected power generation, off-grid power stations, BIPV photovoltaic building integration, etc. The encapsulation films mainly include EVA and PVB.

2. Introduction 

The PVB solar film production machine manufactured by GWELL adopts unique design and advanced manufacturing technology. Improve the stability and automation of the machine. The feeding system is connected with the extruder to realize online accurate proportioning of raw materials, so as to stabilize the quality of PVB solar film and reduce labor cost. The specially designed rollers are used to cool the PVB solar film production machine, reducing the stress caused by uneven cooling and heating, thereby ensuring the correct shrinkage rate.

3. Advantages of PVB solar film:

PVB film is mainly used for BIPV modules, the structure is steel glass (ultra white)-PVB-cell-PVB-tempered glass (normal).PVB solar film production machine.
