GB/T 17601 - 2008 standard specifies the test method for the resistance of refractory materials to sulfuric acid erosion. The standard details the operation process of placing refractory materials in a sulfuric acid environment, and evaluates their resistance to sulfuric acid erosion performance by observing the mass change, Appearance damage and structural integrity change of the material. With the help of this standard, manufacturers can accurately judge the applicability of refractory materials in sulfuric acid-related industrial scenarios, providing a key basis for optimizing product formulations and improving product mass, and ensuring the stability and reliability of refractory materials in high temperature equipment containing sulfuric acid medium.
