The antibacterial mechanism of nano silver powder generally includes the following aspects

The conventional particle sizes of nanoscale silver particles are 20nm, 50nm, 80nm, and 100nm, which can be customized according to requirements.

Nano application scope:
1conductive pastePreparation of electronic pastes for wiring, packaging, and connection in the production of microelectronic components, to achieve miniaturization of microelectronic devices and miniaturization of circuits.
Conductive paste is an important raw material in the electronics industry. A domestic research institution has used nano silver powder instead of micro silver powder to make conductive paste, which can save 30% of silver powder Due to the fact that the melting point of nanoparticles is usually lower than that of solid materials, such as silver, which has a melting point of about 900 ℃, and the melting point of nano silver powder can be reduced to 100 ℃, conductive slurries made from nano silver powder can be sintered at low temperatures, and even low-temperature materials such as plastics can be used as substrates.

2. Antibacterial and antivirus: Additives used in various types of paper, plastic, and textiles for antibacterial and antivirus purposes. 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 brand new anti infection product, it has various properties such as broad-spectrum, no drug resistance, not affected by pH value, long-lasting antibacterial, and non oxidizing blackening. It can be successfully used in architecture, cultural relic protection, and medical products.

The antibacterial mechanism of nano silver powder generally includes the following aspects:
1. The active ingredients in antibacterial fibers act on cell membrane proteins. It can directly damage the bacterial cell membrane, causing the leakage of cell contents. Nano silver adsorbs onto the cell membrane, hindering the absorption of essential nutrients such as amino acids and uracil by bacteria and other microorganisms, thereby inhibiting their growth.
2. The far-infrared radiation released from the surface of antibacterial fabrics within a certain wavelength range can inhibit bacterial activity and lead to bacterial death.

3. The surface catalytic effect of nano silver affects the normal metabolism and reproduction of bacteria, leading to bacterial death.
