炭黑 第21部分：筛余物的测定 水冲洗法
Application Summary AI generated
This standard specifies the water washing method for determining the sieve residue in carbon black, which measures the coarse particles or agglomerates retained on a specified sieve. It is applied in the rubber and plastics industries for quality control of carbon black used as a reinforcing filler in tires, hoses, and other elastomeric products. The method ensures consistent particle size distribution, which directly impacts the processing and mechanical properties of the final rubber compounds.
