GB/T 32695 - 2016 Focus on encapsulated superwater dispersible carbon black. This standard defines the definition and classification of such carbon black. Strict regulations on its technical requirements, such as Particle size distribution, water dispersibility index, coating characteristics, etc. Clear inspection rules, covering sampling, inspection items, judgment criteria. Provide detailed test methods, including dispersion Stability, carbon black content determination. According to this standard, it can accurately control the encapsulated superwater dispersible carbon black mass, screen high-quality raw materials for inks, coatings, water-based battery slurry and other fields, and promote the improvement of industry product performance.
