Sunlight panels come in various forms, and it is necessary to understand the different methods of shaping them so that you know which method to use for forming them in the future. In the process of making sunlight panels, the shaping step is crucial to achieve the desired form. This step can typically be accomplished in two ways: one is the cooling water ring method, and the other is the cooling air ring method. Comparatively, the latter method is more difficult to control and is prone to significant errors due to operational mistakes, so it is recommended to use the cooling water ring method. Simply put, this method involves adjusting the water flow to ensure the sunlight panel surface is evenly acted upon by water, avoiding issues caused by uneven water distribution.

Sunlight Panel Product Characteristics:
(1) Light Transmittance: PC sunlight panels have a light transmittance of up to about 89%, comparable to glass. UV-coated panels are less prone to yellowing, fogging, and poor light transmission when exposed to sunlight. After ten years, the light transmittance loss is about 10%, while PVC loss rates reach 15–20%, and fiberglass about 12–20%.
(2) Impact Resistance: The impact strength is about 250–300 times that of ordinary glass, about 30 times that of acrylic sheets of the same thickness, and about 2–20 times that of tempered glass. It is known as "unbreakable glass" and "resonant steel."
(3) UV Protection: One side of the PC panel is co-extruded with an anti-UV coating, and the other side has anti-condensation treatment, combining UV resistance, thermal insulation, and anti-fogging functions. It blocks ultraviolet rays from passing through, making it suitable for protecting valuable artworks and exhibits from UV damage.
(4) Lightweight: The specific gravity is about half that of glass, reducing costs for transportation, handling, installation, and supporting frameworks.
(5) Flame Retardant: According to the GB50222—95 standard, PC sunlight panels are classified as flame-retardant, i.e., B1 grade. The self-ignition point of PC panels is about 580°C, and they self-extinguish after being removed from the flame. When burning, they do not produce toxic gases and do not contribute to the spread of fire.
(6) Bendability: They can be cold-bent on-site according to design drawings to form arches, semi-circular roofs, and windows. The bending radius is about 175 times the panel thickness, and they can also be heat-bent.
(7) Sound Insulation: PC sunlight panels have significant sound insulation effects, offering better acoustic insulation than glass and acrylic sheets of the same thickness. Under the same thickness conditions, the sound insulation of PC sunlight panels is about 5–9 dB higher than that of glass. They are the material of choice for sound barriers on highways.
(8) Energy Efficiency: Cool in summer and warm in winter, PC sunlight panels have a lower thermal conductivity (K-value) than ordinary glass and other plastics. The thermal insulation effect is about 7–25% higher than that of glass, with PC sunlight panels achieving up to about 49% thermal insulation. This significantly reduces heat loss, making them suitable for buildings with heating systems.
(9) Temperature Adaptability: PC panels do not become brittle at -40°C and do not deform at 125°C. Their mechanical and physical properties remain largely unchanged even in harsh environments.
(10) Weather Resistance: PC sunlight panels can maintain the stability of various physical indicators within a range of -40°C to 120°C. After 4,000 hours of artificial weathering tests, the yellowing degree is 2, and the light transmittance reduction is about 0.6%.
(11) Anti-Condensation: When the outdoor temperature is 0°C and the indoor temperature is 23°C, with indoor relative humidity below about 80%, the inner surface of the material does not condense. Condensation will flow along the surface of the panel and not drip.
