Our company "SIAM HIKIFUNE" performs Japanese quality plating.
The Tokyo head office is a plating pioneer who has been engaged in research and development of surface treatment technology for a long time.
The spread of COVID-19 has made the world more focused on bacteria and viruses.
In this article, we would like to introduce the basic knowledge of antibacterial plating and the research of HIKIFUNE.
What is antibacterial plating?
Antibacterial plating is the process of plating a film to suppress the growth of bacteria.
Metal ions are effective for antibacterial, and it is important to select the correct type of metal to use.
The function of antibacterial metal
Antibacterial metals include the followings:
Has excellent antibacterial properties. Coins made of copper do not allow bacteria to grow even though they are in the hands of many people.
Silver tableware with antibacterial property has been appreciated since long ago.
Copper and silver are superior in antibacterial and antiviral properties, but gold plating is also excellent in corrosion resistance.
Copper and silver metal ions, when dissolved in water, exhibit excellent antibacterial properties even in small amounts. This property is now attracting attention due to the adverse effects of the COVID-19 pandemic.
In addition, metals such as zinc, nickel, titanium, cobalt, and aluminum are also antibacterial.
Effective for faucets and doorknobs
"Antibacterial/antiviral test" of plating researched by HIKIFUNE
We are researching plating with antibacterial and antiviral functions.
■ "Antibacterial properties" test
Bacteria used in the test: Staphylococcus aureus, E. coli
Experiments using Staphylococcus aureus (left) and E. coli (right)
☆ Evaluation points
When the antibacterial activity value is 2 or more (bacterial growth rate is 1/100 or less) compared to the unprocessed product: There is an antibacterial effect
■ "Antiviral properties" test
Bacteria used in the test: Influenza virus, Feline calicivirus (alternative to norovirus)
☆ Evaluation points
When the antiviral activity value is 2 or more (bacterial growth rate is 1/100 or less) compared to the unprocessed product: There is an antiviral effect
The risk of the COVID-19 pandemic and the emergence of unknown viruses will continue in the future.
The HIKIFUNE Group will continue to develop technologies to propose plating that contributes to a safe life for everyone!
