Abstract

The present application provides a method for detecting cable degassing byproducts, which uses an ultraviolet absorption spectrometer (integrating sphere method) to test the ultraviolet absorption spectrum peak of a cable film sample, and the main wavelength range of acetophenone in a liquid solution is between 280nm-290nm, and the main wavelength range of acetophenone in a solid film is between 340nm-350nm. By measuring the absorbance of the sample at a specific wavelength, combined with the acetophenone mass volume concentration-absorbance standard curve, the concentration of acetophenone, a degassing byproduct in the cable, is determined. The detection method only needs to use an ultraviolet spectrophotometer to complete the determination, without the need for a complicated pre-treatment process, and the determination process only takes a few minutes, which is suitable for rapid screening and on-site detection. At the same time, the ultraviolet spectrophotometer equipment cost is relatively low, and no expensive reagents are required during the determination process, which significantly reduces the detection cost.
