玻璃纤维透光性能测试方法研究

Research on the Test Method of Glass Fiber Light Transmittance

玻璃在纤维形态下的透光参数难以测定,需要用同种配方玻璃的透光参数来表征玻璃纤维的透光性能。测试同种配方玻璃的可见光单点透光率T_(550 nm)、红外光单点透光率T_(940 nm)、紫外光单点透光率T_(365 nm)和可见光全波段透光率T_(380-780 nm),用以评价玻璃纤维的透光性能。并在此基础上,以ΔT(ΔT=T_(550 nm)-T_(380-780 nm))来表征可见光透光稳定性。

It is difficult to test the transmittance parameters of glass in the form of glass fiber.The transmittance of glass fiber is characterized by the transmittance parameters of glass with the same formula.The transmittance of glass in glass fiber is tested and evaluated by quoting the visible light single-point transmittance T 550 nm,infrared light single-point transmittance T_(940 nm),ultraviolet light single-point transmittance T_(365 nm)and visible light full-band transmittance_(T 380-780 nm).On this basis,the concept of visible light transmittance stability is characterized byΔT(ΔT=T_(550 nm)-T_(380-780 nm)).
