The photovoltaic frame extrusion production line is a specialized production equipment used for manufacturing photovoltaic module frames. The following is a detailed introduction to the photovoltaic frame extrusion production line:
1、 Working principle
The pultrusion molding process is the main process used in the photovoltaic frame pultrusion production line, which involves impregnating the roving and felt through a resin tank under the pulling action of a traction device, then entering a heating mold for curing, and finally cutting to form the final product.
2、 Application Fields
The products produced by the photovoltaic frame extrusion production line are mainly used in the assembly process of solar panels, as outer frame edge protection, to fix and support the solar cells. Due to its excellent insulation performance and UV resistance, it can provide good protection for silicon wafers and effectively improve the compressive strength and shock resistance of the entire module.
3、 Technical features and advantages
High efficiency and precision: The photovoltaic frame extrusion production line adopts high-strength materials and advanced technology design, which can achieve high efficiency and precision in the production and processing process.
Good corrosion resistance: When used as a building material, the polyurethane frame has the same lifespan as the building and does not require surface treatment. It has strong corrosion resistance to cement slurry in alkaline or acidic environments.
Good dimensional stability: The linear shrinkage rate of continuous fiber-reinforced polyurethane composite material is less than 0.2%, with very little deviation from the design dimensions.
Excellent sealing and insulation performance: The linear expansion coefficient of polyurethane composite doors and windows formed by pultrusion process is much smaller than that of aluminum alloy and PVC plastic, and is close to building walls, effectively avoiding cracks caused by thermal expansion and contraction.
Strong designability: The high fiber content in continuous fiber polyurethane extrusion molding endows the composite material with excellent mechanical properties, with a preferred fiber mass fraction of 60% to 90%. The performance of polyurethane resin has strong designability, and the properties of products obtained from different raw material formulas and additives are also different.
