About Nano Silver fabric layer and antibacterial paperNano Silver consists of nano-sized silver particles, approximately 1 - 100 nanometers. Usually thesize is about 25 nanometers Silver nanoparticles have a large surface area that increases theirexposure to bacteria or fungi thus providing bactericidal effect upon a, Advantages of Nano Silver- Ability to kill more than 650 types of bacteria, 260 types of harmful bacteria that cause disease andboth gram-negative and positive bacteria.- Safe and hardly cause n used in permissible levels).- Keep the nutrition of the food intact.- Quick effect, does not cause irritation, allergies and by-products during the bactericidal process.- No coloring, no harmful smell, extremely flexible application.- Silver Nano has stable properties and can prolong its antibacterial effect for a long time. Selfcleaning ability (made in water) due to its large surface area, Nano Silver can absorb and depositorganic substances, ions as well as other antibiotic residues present in wastewater. cannot be removedby previous mechanical means. Can be combined with other materials such as Nano Copper will havevery strong tocatalytic ability, under the effect of common light can decompose substances present in wastewater into harmless substances.b, Bactericidal Mechanism of nano silverNano Silver attacks HS-SH disulfide connectors on the membrane of unilar organisms(bacteria, fungi, algae) that inhibit the ability to transport oxygen into to kill bacteria, preventover process of copying code of a single-d organismSome other disinfectant mechanisms are also considered by experts to be correct as adsorption theory:the bacterial is disabled as a result of the electrostatic interaction between the negatively chargedsurface of the Silver and ions are adsorbed onto the bacterial surface, which then invadesthe bacterial and neutralizes them.c, Bactericidal paperThis paper have ability to kill virus from 40-5-% during 4-5 hoursSo when we merge two these layer, the mask has BFE more than 99.7%, can meet demand standard ASTM F2100 at level 3.
