    Preparation of steel substrates before application of paints and related products--Specifications for non-metallic blast-cleaning abrasives--Copper refinery slag

    GB/T 17850.3-1999 "Preparation of steel substrates before application of paints and related products - Specifications for non-metallic blast-cleaning abrasives - Copper refining slag" specifies the technical requirements for copper refining slag abrasives used for blast-cleaning steel surfaces before coating. It is applicable to the production and inspection of such non-metallic abrasives. Key indicators include particle size distribution, apparent density, hardness, moisture content, etc., which must be tested using instruments such as test sieves, electronic balances, and hardness testers. This standard provides a benchmark for quality control of abrasives used in steel surface preparation, ensuring the effectiveness of surface treatment before coating application.
