Application Summary AI generated

GB/T 17850.9-2021 specifies the technical requirements for staurolite used as a non-metallic abrasive in blast-cleaning processes to prepare steel surfaces before painting or coating. It is applied in industries such as shipbuilding, construction, and heavy machinery manufacturing, where surface preparation is critical for coating adhesion and corrosion protection. The standard defines parameters like particle size, hardness, and chemical composition to ensure consistent cleaning performance and safety in abrasive blasting operations.
