AI Technical Summary
In the existing technology, the fire resistance limit test of fire-resistant coatings for steel structures in high-radiation environments has the problem of mismatch in the size requirements of the test components, making it difficult to simultaneously meet the specifications and standards of radiation resistance test and fire resistance limit test.
By conducting benchmark thermal insulation efficiency tests and fire resistance limit tests on fire-retardant coatings for steel structures, a linear relationship graph between the benchmark thermal insulation efficiency time and the fire resistance limit time is established. Using this graph, the fire resistance limit time is determined based on the benchmark thermal insulation efficiency time of small-sized components after irradiation, thus achieving size matching.
Under the premise of meeting existing specifications and standards, the fire resistance limit test of fire-retardant coatings for steel structures in high-radioactivity environments was realized, avoiding mismatches in the size requirements of test components and ensuring the consistency of test results.
