Silver Granules Features

  • Antibacterial Properties: Silver granules are known for their strong antibacterial effects, disrupting bacterial cell walls and metabolism to effectively kill bacteria.
  • Electrical Conductivity: Silver granules are excellent conductors, used in conductive inks, pastes, and transparent electrodes in electronics.
  • Optical Properties: Silver granules exhibit Surface Enhanced Raman Scattering (SERS) effects, making them valuable in chemical and biological sensors.

Silver Granules Manufacturing Processes

  • Raw Material Preparation: Select high-purity silver materials to ensure a low level of impurities.
  • Melting: Melt the silver material under vacuum or inert gas protection to ensure uniform composition.
  • Atomization: Use gas or water atomization techniques to break the molten silver into small droplets, forming granules.
  • Sieving: Use sieving to classify the silver granules by particle size, obtaining the required particle size distribution.
  • Surface Treatment: Clean and polish the surface of the silver granules to improve surface smoothness.
  • Quality Inspection: Inspect the composition, particle size distribution, and surface quality of the silver granules to ensure they meet the required standards.

Silver Granules Applications

  • Electronics Industry: Used to manufacture conductive adhesives, conductive inks, and soldering materials for electronic components.
  • Medical Field: Used in producing antimicrobial dressings, medical devices, and drug carriers.
  • Chemical Equipment: Used to manufacture catalysts, chemical reactors, and corrosion-resistant equipment.
  • Optics and Decoration: Used in producing optical lenses, decorative items, and jewelry.
  • Scientific Research: Used in the development and experimentation of new functional materials.
  • Energy Sector: Used in manufacturing solar cells, fuel cells, and battery electrode materials.

Silver Granules Packaging

Silver Granules are carefully placed in wooden cases or cartons with additional soft materials to support and prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
