ActivePreparation of steel substrates before application of paints and related products—Specifications for non-metallic blast-cleaning abrasives—Part 7: Fused aluminium oxide
涂覆涂料前钢材表面处理 喷射清理用非金属磨料的技术要求 第7部分：熔融氧化铝
Application Summary AI generated
This standard specifies technical requirements for fused aluminium oxide used as a non-metallic abrasive for blast-cleaning steel surfaces prior to coating. It is applied in industrial sectors such as shipbuilding, bridge construction, and heavy machinery manufacturing to ensure consistent surface preparation quality for paint adhesion. The standard defines particle size distribution, hardness, and chemical composition for abrasives used in controlled blast-cleaning operations.
