Innovative Design of Masks And Anti-epidemic Products Under The Threat of Coronavirus
The Covid-19 (SARs-CoV-2) virus enters the human respiratory tract in the form of particles and floats through the human nose and mouth until it passes over a long-shaped cell that has ACE2 (angiotensin converting enzyme) and serine protease TMPRSS2 receptors on the surface. The virus will immediately bind to this cell, attack its replication system, use the TMPRSS2 to activate the spike protein on the virus particle, then inserts it into the cell membrane through the Fusion Machinery of the spikes, which is open up now instead of folding up, while opening the outer layer of the cell membrane, the viral RNA and N protein.....
Why ACTife’s antibacterial technology is particularly effective
＊The structure of various viruses
The structure of a virus is genetic material (RNA or DNA) covered by coat protein.
The external structure is divided into:
1. Viruses with envelope: such as the new coronavirus (RNA genetic material). Usually only survives a few days outside the body.
2. Viruses without an envelope: such as the norovirus, that causes gastroenteritis, as well as enterovirus, which is a pandemic in Taiwan almost every year. It usually survives....
The Invasion And Infection of Coronavirus
There are thousands of coronaviruses have been found, there are four of them that are related to the influenza, and the other two have caused epidemics that are sufficient to warn the human public health crisis. They included the SARS epidemic in 2002, which caused approximately 770 deaths worldwide. And MERS in 2012, which caused about 800 deaths worldwide. Among them, SARS disappeared bizarrely a year after the epidemic, while MERS still exists in the human world....
The Concept of HEPA
How To Design An Effective Anti-epidemic Mask
What is HEPA?
HEPA stands for High-Efficiency Particulate Air Filter, which can be made of filter paper, non-woven fabric, or glass fiber. According to the definition of the U.S. Department of Energy, a filter that can block more than 99.7% of suspended particles with a size of 0.3 microns is a HEPA filter. It is interwoven by very fine fibers, which can capture particles very effectively.
The way how HEPA filters air is not like sieving particles, in fact, HEPA filters rely on the adsorption of fiber....
Definition Of Effective Anti-epidemic Mask
Viruses spread in the air with two methods.
First method: It is a widespread method of transmission that has been confirmed, and it’s transmitted through droplets. The so-called droplet is through airborne and the spread of pollution on the surface where it falls. According to the size of the droplet, we can simply divide it into the following three situations.
Mechanism of Antibacterial And Virus Deactivation Technology
The above report is that Israel has developed a long-lasting antibacterial technology for Nano-copper coating, which is one of the most advanced and representative technologies for chemical binding metal ions to achieve antibacterial effect. Its basic principle is as follows.
