Product Description

PVB Encapsulation Film Production Line Use Single Screw Extruder For BIPV Panels

 

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.

 

1. Introduction of PVB encapsulation film production line

The PVB encapsulation film production line 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 encapsulation film and reduce labor cost. The specially designed rollers are used to cool the PVB encapsulation film evenly, reducing the stress caused by uneven cooling and heating, thereby ensuring the correct shrinkage rate.PVB encapsulation film production line

 

2. Advantages of PVB encapsulation film:

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

3. Comparison of PVB encapsulation film and EVA encapsulation film:

EVA is a thermosetting resin with cross-linking reaction; PVB is a thermoplastic resin with reproducibility and no cross-linking reaction;

The domestic glass curtain wall specification clearly puts forward the regulation of "application of PVB". BIPV photovoltaic modules can be made by PVB instead of EVA to achieve a longer service life.

PVB has strong adhesive properties, and its safety is higher than that of EVA film;

EVA has many formulas, and the packaging process is not easy to control; the formula of PVB film is simple, the quality control is stable, and the shelf life is long;

PVB film has poor fluidity, which can prevent film overflow during processing.
