Method and system for detecting structural performance of fire retardant disc

A method for detecting structural performance of a fire retardant disc, wherein the fire retardant disc comprises a plurality of passages, the method comprising the steps of:

• S1:
• obtaining passage structural information characterizing a structural feature of each passage in the fire retardant disc;
• S2:
• analyzing the passage structural information and measuring a key feature size of each passage;
• S3:
• statistically analyzing feature size distribution of each passage according to the key feature size, and determining a structural uniformity state of the fire retardant disc based on a statistical result of the statistical analysis of feature size distributions of the plurality of the passages;
• S4:
• constructing an objective correlation function with an effectiveness of fire retardant performance of the fire retardant disc as an objective, and a cumulative use time of the fire retardant disc and a structural error corresponding to the statistical result of the feature size distribution of the plurality of passages in the fire retardant disc as influencing factors;
• and
• S5:
• predicting a remaining life span of the fire retardant disc based on an acceptable error threshold of effectiveness reaching a limiting fire retardant performance through the objective correlation function.
