Aia nā ʻano like ʻole o nā kukuna ultraviolet i ka lā, e like me ka hoʻokaʻawale ʻana o nā hawewe lōʻihi, hiki ke hoʻokaʻawale ʻia nā kukui ultraviolet i UVA, UVB, UVC ʻekolu, a hiki i ka ʻili o ka honua ma o ka papa ozone a ʻo nā ao ka nui o UVA a me UVB. nā kukui ultraviolet band, a e ālai ʻia ka UVC. Hiki iā mākou ke hoʻohana i nā hiʻohiʻona o nā hawewe like ʻole o nā kukuna ultraviolet i ke kahua ʻoihana e hoʻolālā a hoʻomohala i nā huahana moʻo ultraviolet me nā hana like ʻole, i mea e hoʻomaʻamaʻa ai i ka helu ʻana o ka ikaika ultraviolet, i ʻike ʻia ma ke ao holoʻokoʻa e like me ka hoʻohana ʻana i kahi ʻāpana hui e ana a helu. ʻO nā ʻāpana e ana i ka ikaika ultraviolet he μW / cm2, mW / cm2, W / cm2 a me W / m2, a pili nā ʻoihana like ʻole i nā ʻāpana like ʻole.
ʻO ka mea mua, e hoʻohana i nā kukui ultraviolet
Ma ka lōʻihi nalu:
13.5nm mamao-UV lithography
30-200nm hoʻokaʻawale kiʻi kiʻi, ultraviolet photoelectron spectroscopy
230-365nm hōʻailona barcode scanning, UV ʻike
230-400nm optical sensors, nā ʻano mea hoʻāʻo like ʻole
240-280nm Disinfection a me ka hoʻomaʻemaʻe ʻana i nā ʻili a me ka wai (ʻo ka nalu nui no ka absorption DNA ʻo 265nm)
200-400nm Forensic Testing, Drug Testing
270-360nm Opal Analysis, DNA Sequencing Analysis, Drug Detection
280-400nm cellular lāʻau lapaʻau imaging
300-320nm lāʻau lapaʻau māmā
300-365nm ho'ōla o nā polymers a me nā inika
300-400nm kiʻiʻoniʻoni a me ke kukui kīwī
350-370nm mea hoʻopau (ʻoi aku ka hoihoi ʻia o nā iniseti lele ma 365nm luminosity)
2. ʻO ka hoʻololi ʻana o ka ʻāpana ikaika Ultraviolet
Ma muli o nā nalu like ʻole o nā kukui ultraviolet, ʻokoʻa ka hopena, a ʻaʻole hoʻohana ʻia nā huahana i loaʻa mai kēia. Hoʻohana nā ʻoihana like ʻole i nā huahana ultraviolet, pono e hoʻomalu i ka ikaika ultraviolet, pono i kekahi mau ʻoihana ke ana ʻia ka ikaika ultraviolet i uW (heluhelu e like me nā microwatts), e like me nā kukui germicidal ultraviolet puka maʻamau, e hoʻohana kekahi mau ʻoihana i nā kukui germicidal ultraviolet kiʻekiʻe, pono e ana ʻia ma W, μW, MW, W nā ʻāpana mana honua, a ʻo cm2, m2 nā ʻāpana ʻāpana honua, no laila e hōʻike ana ka ikaika ultraviolet i ke ana ʻana i ka ikaika o ka hoʻomālamalama ultraviolet i kēlā me kēia ʻāpana. wahi. No ka laʻana, 200mW/cm2 e hōʻike ana he 200mW ka nui o ka irradiation UV i ana ʻia ma kahi ākea o 1 square meter.
E lawe iā Changzhou Guangtai LIGHTBEST brand ultraviolet germicidal lamp ma ke ʻano he laʻana:
ʻO ke kumu hoʻohālike mua ma ka lālani mua ʻo GPHA212T5L/4P UV ikaika ma hoʻokahi mika: 42μW/cm2. ʻO ka ʻōlelo maʻamau, ʻoi aku ka nui o ka mana o ke kukui, ʻoi aku ka nui o ka ikaika o ka ultraviolet, no ka laʻana, ʻo ka laina laina hope loa ʻo GPHHA1790T12 / 4P 800W, a ʻo ka ikaika ultraviolet i hoʻokahi mika: 1700μW/cm2.
No laila he aha ka ratio hoʻololi ma waena o kēia mau ʻāpana?
Ka hoʻololi 'ana o ka mana: 1W = 103 mW = 106μW
Huli ʻāpana ʻāpana: 1 m2=104 cm2
Ka hoʻololi ʻana o ka ʻāpana ikaika o UV:
1 W/m2 =103 W/cm2=104 mW/cm2=106μW/cm2
ʻO ia hoʻi: 1 W/m2> 1 W/cm2> 1 mW/cm2> 1μW/cm2
