performance and advantages of FRP skylight panel
The full name of FRP is glass fiber reinforced polyester skylight. It is a substitute for skylight composed of high-performance film, high-quality polyester and reinforced glass fiber. The company introduces the British advanced FRP plate automatic continuous consumption line, adopts the high-quality raw materials of well-known manufacturers at home and abroad, adopts DuPont 301 and ganware-pt055 films imported from the United States, and adopts water and dust-free cutting technology for edge cutting.
Strength refers to the maximum stress value in the object when the FRP skylight is damaged by force, including tensile, bending, shear and other strengths. That is, whether it is firm or not.
Rigidity refers to the ability of FRP daylighting board to resist deformation. Therefore, when FRP daylighting board is formed, the rigidity can be improved by making reinforcing bars at some parts or making reinforcing bars with sub fibers on the surface.
The curing degree of FRP skylight is Greater than or equal to 85 percent , so the skylight consumed by our company has both rigidity and toughness, and is not brittle, which is convenient for construction and installation.
extinction of FRP skylight panel
Extinction means oxidation. Under normal conditions, the FRP skylight consumed by our company with oxidation number Less than or equal to 21 percent is flammable. It will be extinguished automatically in case of open fire. The higher the temperature, the easier it will be extinguished. Therefore, in case of a fire, the skylight can be extinguished quickly and become a smoke exhaust belt. According to the insoluble, insoluble and fusible properties, the FRP skylight panel by our company is a thermosetting product, which will not produce melt drop phenomenon when extinguished. When the oxygen index is Greater than or equal to 28 percent , it is a flame-retardant day lighting sheet, that is, it can extinguish itself from the fire, not non combustible but passive extinguish. When it comes into contact with the flame, it shows the phenomena of temperature rise, thermal synthesis, ignition, continuous extinction and so on.
effect of temperature on the strength of FRP skylight sheet
Like many data, the strength of FRP daylighting board decreases with the increase of temperature. When the temperature rises to a certain value, the strength decreases sharply. In addition, unlike other materials that become brittle at low temperature, FRP has good low temperature performance, and the strength tends to increase with the decrease of temperature at - 70 degree . Therefore, the FRP daylighting board will not age, turn yellow, crack or soften under the condition of 20 degree - 95 degree .
