FRP sheet is made of thermosetting
fiberglass and reinforced plastic. As a composite material, it is
optically nonuniform. Working long in the factory covered by FRP
sheets won’t make the workers feel tired. It is also energy-saving.
Moreover, the Anti-ultraviolet film covered on the surface can
greatly extend the service life of the sheets.
Normally, the
oxidation number of an FRP sheet is no more than *1%, which means
it is deflagrable. It burns itself when facing any flame, and the
higher the temperature the easier the burning will be. Once in a
fire accident, FRP sheet will burn up fast enough to make
oxygenexhaust. FRP sheet is
thermosetting, so there will no drops when it is burning. When
oxidation number is equal or higher than *8%, the sheet will be
flame resistant and self-extinguishing once away from fire. When
facing flames, high temperature, or pyrolysis, it will get into
sustained combustion.
Like other lighting sheets, the
intensity of FRP will decline as the temperature rises. When the
temperature rises to a specific value, its intensity will decline
sharply. It is unlikely to age, yellow, break or soften when the
temperature varies from *0℃ to *5℃. FRP can resist low temperatures
while some other materials can not. When the temperature drops to
**0℃, its intensity tends to rise if the temperature continues to
decline.
