Antibacterial Ag Nanopowder Buy Silver Nanoparticles High Purity

Antibacterial Ag Nanopowder Buy Silver Nanoparticles High Purity

Code: A110

Package:25g, 50g, 100g in double anti-static bags.

Application ranges:

1. Conductive paste: prepare electronic pastes such as wiring, packaging, and connection in the production of microelectronic components, so as to miniaturize microelectronic devices and miniaturize circuits.

Conductive paste is an important raw material for the electronics industry. Some domestic research institutions use nano-silver powder instead of micro-silver powder to make conductive paste, which can save 30% of silver powder. Since the melting point of nanoparticles is usually lower than that of solid substances, for example, the melting point of silver is about 900 ℃, while the melting point of nano-silver powder can be reduced to Therefore, the conductive paste made of nano-silver powder can be sintered at low temperature, and even low-temperature materials such as plastics can be used as substrates.


2. Antibacterial and antivirus: additives in various papers, plastics and textiles are used for antibacterial and antivirus. About 0.1% of nano-layered silver-based inorganic antibacterial powder has strong inhibitory and killing effects on dozens of pathogenic microorganisms such as Escherichia coli and Staphylococcus aureus. As a new anti-infective product, it has broad-spectrum, no drug resistance, unaffected by pH value, long-lasting antibacterial, non-oxidative blackening and other properties. It can be successfully used in construction, cultural relics protection and medical products.


The antibacterial mechanism of nano silver powder generally has the following aspects:

1. The active ingredients in antibacterial fibers act on cell membrane proteins. It can directly destroy the bacterial cell membrane, resulting in the exudation of cell contents, and the nano-silver is adsorbed on the cell membrane, which hinders the absorption of nutrients necessary for growth such as amino acids and uracil by microorganisms such as bacteria, thereby inhibiting their growth.
2. Far-infrared rays in a certain wavelength range are released from the surface of the antibacterial fabric, which can inhibit the activity of bacteria and cause the death of bacteria.
3. The surface catalysis of nano-silver affects the normal metabolism and normal reproduction of bacteria, resulting in the death of bacteria.
