| titleOfInvention | Method for analyzing types and content of ultraviolet absorbers in polycarbonate |
| abstract | The invention discloses an analysis method of an ultraviolet absorbent in polycarbonate, which comprises the steps of firstly preparing polycarbonate with 10-1000 ppm of the ultraviolet absorbent commonly used in polycarbonate, using a spectrophotometer to carry out spectrum scanning and archiving at the wavelength of 280-350 nm, then detecting a sample to be analyzed and polycarbonate without adding UV, comparing the waveform and transmittance with the archived spectrum, and judging the type and the content of the ultraviolet absorbent added in the polycarbonate. The invention has the advantages of common equipment, simple operation, high detection speed and reliable detection result. |
