| Detailed Product Description： | UV principle:
UV is an electromagnetic wave, high-energy electrons from the atoms in order to jump when the low-order, will release excess energy in electromagnetic waves. The energy of electromagnetic waves, the stronger the shorter the wavelength, the wavelength of the human eye can see 400nm-780nm (1nm = 10-9m), to the naked eye is, 400nm of the electromagnetic waves appear as blue, purple, 780nm of the electromagnetic waves appear as orange, red . 400nm UV is also shorter than the wavelength of electromagnetic waves, because of its spectrum outside the area in purple, named for the UV (Ultraviolet, referred to as UV). Is the wavelength of ultraviolet light through means of electromagnetic waves in the 100-400nm, the human eye can not see ultraviolet light.
100-400nm wavelengths of ultraviolet light, according to their effect on human health and function, UV-A, UV-B, UV-C and V-UV.
UV-A is the wavelength 315-400nm UV, UV-A makes the skin produce melanin, the skin black.
UV-B is the wavelength of 280-315nm in the UV, UV-B can cause cancer, skin wrinkles aging.
UV-C wavelength of 200-280nm, 254nm bands which have sterilization and disinfection performance.
In the 240-270nm wavelength of UV-C can directly damage cells, viral DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), so that the rapid death of microorganisms.
In the 100-200nm wavelength of VUV185nm can produce ozone, and in the air or ozone dissolved in water, microorganisms can damage the cell wall to oxidation, the microbial died immediately. Principles of ultraviolet disinfection To know what on earth all life forms are based on DNA and RNA as breeding, remains the foundation. DNA and RNA are 4 kinds of chemicals modules A - Adenine Adenine T - Thymine Thymine C - Cytosine cytosine, oxygen ammonia pyrimidine G - Guanine Ukraine dobutamine pyridine (basic components of nucleic acids) When cell proliferation, DNA in the long-chain open, opened a long chain length of each unit will look for A-Link T cells, each copy of long-chain can be separated out and just another long chain of the same chain, to restore the original complete pre-split DNA, as the basis for new cells. In the 240-270nm wavelength UV can break the production of proteins and DNA replication ability. Bacteria and viruses DNA, RNA production of proteins by the destruction of their ability and reproductive capacity have been lost. Caused by bacteria, viruses, usually a very short life cycle, the bacteria can not reproduce, the virus will quickly die. |
