According to the main experiments, there is a data in which high antibacterial effects are shown for bacteria such as S. aureus, E. coli, MRSA, Salmonella, and vibrio.
It is said that it is also to prevent rotten cuisine in a lacquered paper box from a long time to the year, and it is said that it prevents corruption by a bacteria and to make a slight danger.
Research results of new coronavirusAnd this time, there was a report that it was confirmed that the lacquer has the effect of reducing the new coronavirus by lacquer, which is selling lacquer in Fukui Prefecture.
The new coronavirus was brought into contact with lacquered acrylic plates and the number was confirmed after 24 hours and the number of viruses decreased by more than 99.9% compared to those not painted.
For more information, see the following citations.
In the General Foundation In Japan Textile Product Quality Technology Center, as a result of verifying the antiviral effect on new coronavirus (SARS-COV-2) on a test plate applied to the Company's lacquer, its effect was confirmed.
The procedure of this verification test method is used as a quasi-co-test plate with a virus on a lacquer-painted plate and a raw test plate, with a subsequent application of FIG. 1 "ISO 21702 plastic and other non-porous surface antiviral surfaces" and after 24 hours It was confirmed that the infection value of the recovered virus (the number of viral particles with cell infectivity) was measured, and the lacquered plate decreased by 99.9% or more compared with the raw product. See Figure 2

As far as this experiment is seen, the new coronavirus of lacquered surfaces is most about 24 hours.
According to the homepage of Nagoya University General Health Physical Education Center,
"The virus adhered to the surface of the object is 3 hours, 3 hours, copper (coin), 3 to 8 hours in cardboard, 2 days with trees and cloths, 3 days in glass and banknotes, 7 days in plastic and stainless steel I will die by the progress. "It is.
It is subtle that it is subtle how much usefulness to the lacquerware against daily infection risks, but it is no doubt that the antiviral effect is high compared to wood, plastic, plastic and stainless steel dishes.
Of course, in order to prevent infection, it goes without saying that basic measures such as hand disinfection and mask wear are required.
However, if there are many people who are interested in lacquerware or those who are going to incorporate lacquerware on a daily basis, you are happy as long as they are more than one person.
