AI Technical Summary
Existing testing methods cannot effectively distinguish and quantify the retention rate and attenuation of flame retardant properties of flame retardant materials after thermal shock, resulting in inaccurate evaluation results.
By constructing a three-dimensional density gradient field, extracting density anomaly feature surfaces, generating a spatial polyhedral cone, and calculating the non-uniformity modulation coefficient of flame retardant distribution, the vertical combustion and oxygen index test data are calibrated to evaluate the flame retardant performance retention rate or attenuation degree.
This method enables intuitive and quantitative characterization of the distribution of flame retardants within flame-retardant materials, eliminates testing errors, and improves the accuracy and objectivity of flame-retardant performance evaluation after thermal shock, providing a basis for environmental adaptability evaluation of flame-retardant materials used in electronic packaging.
