Silver has a health care function. Making tea with silver cups can kill viruses, sterilize, beautify, improve human immunity and promote human health. "Compendium of Materia Medica" says that silver has the effects of "calming the five internal organs, calming the mind, treating fright, strengthening bones and muscles, and improving eyesight".

Modern research points out that the chemical structure of silver determines that silver has high catalytic ability, and the reduction potential of highly oxidized silver is high enough to produce atomic oxygen in its surrounding space. Atomic oxygen is highly oxidizing and can kill bacteria. Ag+ can strongly attract sulfhydryl group (-SH) on protease in bacteria, and quickly combine with it, making protease inactive and leading to bacterial death.

When the bacteria were killed by Ag+, Ag+ was released from the bacteria and then contacted with other colonies, which may be the reason for the persistence of silver sterilization.

Application of silver

Pure silver is a beautiful silvery white metal with good ductility, and its electrical conductivity and thermal conductivity are the highest among all metals. Silver is often used to manufacture highly sensitive physical instruments and components, various automation devices, rockets, submarines, computers, nuclear devices and communication systems. A large number of contacts in all these devices are made of silver.

In the process of use, each contact has to work for millions of times, and it must be wear-resistant and reliable, and can withstand strict working requirements. Silver can meet all kinds of requirements.
