Its purity varies according to different application requirements, and some may contain trace amounts of other elements that help stabilize the performance of silver powder or enhance dispersibility, but silver content is relatively high and is the key to exerting antibacterial effects.\t\t<\/div>\n\t<\/div>\n\t\t<div id=\"accordion-4000283244\" class=\"accordion-item\">\n\t\t<a id=\"accordion-4000283244-label\" class=\"accordion-title plain\" href=\"#accordion-item-physical_properties\" aria-expanded=\"false\" aria-controls=\"accordion-4000283244-content\" >\n\t\t\t<button class=\"toggle\" aria-label=\"Toggle\"><i class=\"icon-angle-down\"><\/i><\/button>\n\t\t\t<span>Physical Properties<\/span>\n\t\t<\/a>\n\t\t<div id=\"accordion-4000283244-content\" class=\"accordion-inner\" aria-labelledby=\"accordion-4000283244-label\" >\n\t\t\tThe appearance is a grayish-white or silvery-gray fine powder with good metallic luster. Its particle size is generally at the micron level or even nanometer level, the smaller the particle size, the larger the specific surface area, and the better the antibacterial performance. The texture is delicate, the density is large, it has good electrical conductivity, and it is insoluble in water and common organic solvents and can maintain a relatively stable physical state under normal conditions.\t\t<\/div>\n\t<\/div>\n\t\t<div id=\"accordion-1584551481\" class=\"accordion-item\">\n\t\t<a id=\"accordion-1584551481-label\" class=\"accordion-title plain\" href=\"#accordion-item-chemical_properties\" aria-expanded=\"false\" aria-controls=\"accordion-1584551481-content\" >\n\t\t\t<button class=\"toggle\" aria-label=\"Toggle\"><i class=\"icon-angle-down\"><\/i><\/button>\n\t\t\t<span>Chemical Properties<\/span>\n\t\t<\/a>\n\t\t<div id=\"accordion-1584551481-content\" class=\"accordion-inner\" aria-labelledby=\"accordion-1584551481-label\" >\n\t\t\tIt has a relatively stable chemical nature and does not easily undergo chemical reactions with air, water, and most common chemical substances under normal temperature and pressure. However, silver is prone to react with sulfur-containing compounds, and long-term exposure to a sulfur-containing environment may cause surface discoloration, but this does not affect its inherent antibacterial function. It has strong antioxidant properties and can maintain its chemical characteristics for a long time.\t\t<\/div>\n\t<\/div>\n\t\t<div id=\"accordion-1450212112\" class=\"accordion-item\">\n\t\t<a id=\"accordion-1450212112-label\" class=\"accordion-title plain\" href=\"#accordion-item-antibacterial_principle\" aria-expanded=\"false\" aria-controls=\"accordion-1450212112-content\" >\n\t\t\t<button class=\"toggle\" aria-label=\"Toggle\"><i class=\"icon-angle-down\"><\/i><\/button>\n\t\t\t<span>Antibacterial Principle<\/span>\n\t\t<\/a>\n\t\t<div id=\"accordion-1450212112-content\" class=\"accordion-inner\" aria-labelledby=\"accordion-1450212112-label\" >\n\t\t\tThe antibacterial action of antibacterial silver powder mainly depends on the release of silver ions. Silver ions have strong activity. When silver powder meets bacteria and other microorganisms, silver ions will be gradually released, and then interact with the cell wall, cell membrane, and proteins, nucleic acids and other biomacromolecules inside the bacterial cells. It can denature and inactivate bacterial proteins, disrupt bacterial metabolic processes, hinder their reproductive capabilities, and even directly lead to bacterial death, thereby achieving efficient antibacterial effects, and has inhibitory and lethal effects on a variety of common harmful bacteria and fungi.\t\t<\/div>\n\t<\/div>\n\t\t<div id=\"accordion-2706705839\" class=\"accordion-item\">\n\t\t<a id=\"accordion-2706705839-label\" class=\"accordion-title plain\" href=\"#accordion-item-safety_and_stability\" aria-expanded=\"false\" aria-controls=\"accordion-2706705839-content\" >\n\t\t\t<button class=\"toggle\" aria-label=\"Toggle\"><i class=\"icon-angle-down\"><\/i><\/button>\n\t\t\t<span>Safety and Stability<\/span>\n\t\t<\/a>\n\t\t<div id=\"accordion-2706705839-content\" class=\"accordion-inner\" aria-labelledby=\"accordion-2706705839-label\" >\n\t\t\tWhen used reasonably, antibacterial silver powder is relatively safe. Since silver itself has a certain biocompatibility, and its usage in products is usually strictly controlled, it generally does not pose significant harm to human health. Its antibacterial performance is relatively stable, if there are no extreme destructive factors in the environment, such as strong acid and alkali corrosion, it can continuously exert antibacterial effects for a long time. However, with the increase in usage time and the continuous release and consumption of silver ions, the antibacterial effect may weaken to a certain extent, but it can be ensured to be long acting through reasonable process design and other methods.\t\t<\/div>\n\t<\/div>\n\t\t<div id=\"accordion-2578849720\" class=\"accordion-item applicationaccordion\">\n\t\t<a id=\"accordion-2578849720-label\" class=\"accordion-title plain\" href=\"#accordion-item-application_scenarios\" aria-expanded=\"false\" aria-controls=\"accordion-2578849720-content\" >\n\t\t\t<button class=\"toggle\" aria-label=\"Toggle\"><i class=\"icon-angle-down\"><\/i><\/button>\n\t\t\t<span>Application Scenarios<\/span>\n\t\t<\/a>\n\t\t<div id=\"accordion-2578849720-content\" class=\"accordion-inner\" aria-labelledby=\"accordion-2578849720-label\" >\n\t\t\t\n<h3>Medical Field<\/h3>\n<div class='applicationdiv'>\n<h4>Medical Device Coatings<\/h4>\n<p> Adding antibacterial silver powder to the surface coating materials of various medical devices (such as surgical knives, tweezers, catheters, etc.) gives the device surface antibacterial ability, effectively reducing the attachment and breeding of bacteria on the device, reducing the risk of cross-infection during the use of medical devices, ensuring the safety and hygiene of medical operations, and is especially significant for medical devices that need to be used frequently or left in the human body for a long time.<\/p>\n<h4>Medical Dressings<\/h4>\n<p> Used to make medical gauze, band-aids and other dressings, the antibacterial silver powder can slowly release silver ions to inhibit the proliferation of bacteria around the wound, prevent wound infection, accelerate wound healing, provide better protection for patients&#8217; wound care, and reduce the pressure on medical staff to monitor wound infections.\n<\/p><\/div>\n<h3>Textile Industry<\/h3>\n<div class='applicationdiv'>\n<h4>Antibacterial Textile Production<\/h4>\n<p> Added to textile fibers to produce clothing, bedding, towels and other textiles with antibacterial functions.
