SGP solar encapsulation film production line

SGP Photovoltaic Packaging Adhesive Film Production Line

1. Introduction to SGP encapsulation film production line

The SGP encapsulation film production line manufactured by GWELL adopts unique design and advanced manufacturing technology. Improved the stability and automation level of the machine. The feeding system is connected to the extruder to achieve online precise proportioning of raw materials, ensuring stable SGP film quality and reducing manual labor. Using specially designed rollers to evenly cool the SGP film, reducing stress caused by uneven heating and cooling, thereby ensuring the correct shrinkage rate. Due to the high viscosity of SGP film, we have added an isolation film unwinding device to effectively prevent SGP film from sticking together during winding.

3. Introduction to SGP encapsulation film:

SGPThe adhesive film is mainly used for BIPV modules, with a structure ofSteel glass (ultra white)-SGP-Battery cells-SGP-Tempered glass (ordinary)

At present, the packaging forms of photovoltaic modules mainly include glass EVA backplane packaging and glass-SGP-There are two forms of glass.I willtoSGP packagingadhesive filmSGP packaging film production lineElaborated on it.

Photovoltaic is a rapidly developing emerging industry that converts solar energy into electrical energy. Among them, crystalline silicon solar cell modules are mainly used in large-scale grid connected power generation, off grid power stations, BIPV photovoltaic building integration, etc,The SGP encapsulation film production line is mainly used for BIPV building photovoltaic modules.

4. SGP encapsulation filmWith EVAEncapsulation filmcomparison：

EVA belongs to thermosetting resins and undergoes cross-linking reactions;SGPBelonging to thermoplastic resin, with repeatability and no cross-linking reaction;

The domestic glass curtain wall standards clearly state the "applicationSGP”According to regulations, BIPV photovoltaic modules adoptSGPReplacing EVA production can achieve a longer service life.

SGPHas strong adhesive performance and higher safety than EVA film;

There are many formulas for EVA, and the packaging process is difficult to control;SGPThe formula of the membrane is simple, the quality control is stable, and the shelf life is long;

SGP adhesive filmPoor fluidity can prevent the overflow of the adhesive film during the processing.

5. Comparison between SGP film and PVB encapsulation film:

Excellent mechanical properties：Higher intensity. At the same thickness, the bearing capacity of SGP interlayer is twice that of PVB; Under the same load and thickness, the bending deflection of SGP laminated glass is one fourth that of PVB;

tear resistance：At the same thickness, the tear strength of PVB laminated film is 5 times that of PVB, and it can still adhere to glass without causing the entire glass to fall off.

Strong stability and moisture resistance：SGP laminated film is colorless and transparent, resistant to ultraviolet rays, and is not easily yellowed after long-term exposure to sunlight and rain. The yellowing coefficient is less than 1.5, while the yellowing coefficient of PVB laminated film is 6-12. Although SGP's production process is similar to PVB.
