Pholiso ea LED ea UV ke eng?

Pholiso ea UV LED ke mokhoa o sebelisang leseli la ultraviolet ho phekola kapa ho thatafatsa lintho. Mokhoa ona o kenyelletsa ho pepesa lisebelisoa ho li-diode tsa UV tsa LED tse ntšang leseli la UV. Ha leseli la UV le otla ntho, le qala tšebetso ea lik'hemik'hale e etsang hore ntho eo e thatafale kapa e rarolle. Li-diode tsa UV tsa LED li hlahisa leseli la UV-A, UV-B, le UV-C, tse tsamaellanang le bolelele ba maqhubu a hlokahalang ho qala ts'ebetso ea ho folisa.

Mokhoa ona oa ho phekola ke theknoloji e ncha e sa tsoa tuma. Ke mokhoa o sebetsang haholoanyane le o bonolo ho feta oa ho phekola UV ka mabone a mouoane a mercury. Pholiso ea LED ea UV  e na le melemo e mengata ho feta pheko e tloaelehileng ea UV, ho kenyelletsa tšebeliso e tlase ea matla, nako e telele ea bophelo ba sistimi, le ho ba sieo ha mouoane oa mercury.

Pholiso ea LED ea UV e sebetsa Joang?

Pholiso ea LED ea UV  e sebetsa ka ho ntša leseli la UV sebakeng sa maqhubu a maqhubu a 365-405 nm, e leng se qalang mokhoa oa ho folisa. Leseli le qala karabelo ea lik'hemik'hale e etsang hore thepa e thatafale kapa e fole ha e otla thepa. Mokhoa ona o bitsoa photopolymerization.

Leseli la UV le kenya tšebetsong photoinitiator ka har'a thepa, e leng motsoako oa lik'hemik'hale o qalang mokhoa oa ho folisa, nakong ea photopolymerization. Photoinitiator e monya leseli la ultraviolet mme e hlahisa li-radicals tsa mahala, tse sebetsanang le li-monomer tsa thepa ho etsa lipolymer. Joale li-polymers li kopana ho etsa ntho e tiileng, e phekotsoeng.

Melemo ea ho Fokotsa LED ea UV

Pheko ea LED ea UV e na le melemo e mengata ho feta mekhoa e tloaelehileng ea ho folisa, joalo ka mocheso kapa pheko e thehiloeng ho solvent. Har'a melemo ea mantlha ea pheko ena ke:

Mokhoa o sebetsang hantle oa matla

Pholiso ea LED ea UV  e hlahisa thepa ea boleng bo holimo e phekotsoeng e nang le thepa e ntlafalitsoeng, e kenyelletsang ho tšoarella ho eketsehileng, ho hanyetsa mahlaba, le ho khomarela. Sena ke hobane ts'ebetso e etsa hore ho be le taolo e nepahetseng holim'a maemo a pheko, joalo ka matla a khanya le nako.

Ho feto-fetoha ha maemo

Pholiso ea LED ea UV e ka sebelisoa ho phekola mefuta e sa tšoaneng ea lintho tse kang likhomaretsi, lidae le litlolo. Ho feta moo, ts'ebetso ena e sebetsa ho li-substrates tse fapaneng, ho kenyeletsoa polasetiki, tšepe le ceramic.

Lisebelisoa tsa LED tsa UV bakeng sa ho Fokotsa

UV LED disinfection e na le mefuta e fapaneng ea likopo tsa indasteri, ho kenyeletsoa:

Tsa makoloi

Pheko ea UV ea LED e sebelisoa indastering ea likoloi ho phekola liphahlo le likhomaretsi. Tshebetso ena e molemo haholo indastering ea likoloi, moo lebelo le leng bohlokoa ho finyella litlhoko tsa 'maraka. E boetse e sebelisetsoa ho phekola lijase tse hlakileng tse kentsoeng ka ntle ho koloi ho e sireletsa linthong tsa tlhaho.

Tsa elektroniki

Pheko ea LED ea UV e sebelisoa indastering ea lisebelisoa tsa elektroniki ho phekola likhomaretsi le li-encapsulants. Likarolo tsena li sebelisetsoa ho etsa lisebelisoa tsa elektroniki tse kang li-smartphone, matlapa le likhomphutha. E boetse e sebelisetsoa ho phekola limaske tsa solder, tse sebelisoang nakong ea ts'ebetso ea solder ho sireletsa bokaholimo ba liboto tsa potoloho tse hatisitsoeng (PCBs).

Sepakapaka

Ha ho hlokahala phekolo e nepahetseng, liindasteri tsa bongaka le tsa meno hangata li sebelisa mekhoa ea ho phekola matheba. Liindastering moo lebelo le ts'ebetso e sebetsang hantle li leng bohlokoa, joalo ka liindasteri tsa likoloi le tsa elektroniki, hangata ho sebelisoa mekhoa ea ho phekola likhohola.

Lintlha Tseo U li Nahanang Ha U Khetha Sisteme ea Pheko ea LED ea UV

Ho na le lintlha tse ngata tse lokelang ho nahanoa ha u khetha a UV LED pholiso s tsamaiso, joalo ka:

Phekolo ea Thepa:

Thepa e hlokahalang bakeng sa kopo e itšetlehile ka litlhoko tse itseng tsa thepa e phekoloang. Nako ea ho folisa ea lebone la UV, matla le bolelele ba maqhubu ke lintlha tsa bohlokoa tse lokelang ho nahanoa. Nahana ka nako e hlokahalang ea ho folisa thepa, kaha lisebelisoa tse ling li ka hloka nako e telele ho feta tse ling.

Ho bohlokoa ho netefatsa hore matla a lebone la UV a lekane ho fihlela thepa e lakatsehang ea ho folisa, kaha ke eona e bontšang hore na thepa e tla fola kapele hakae. Hoa hlokahala hape ho nahana ka bolelele ba maqhubu a lebone la UV le sebelisetsoang ho folisa, kaha lisebelisoa tse fapaneng li hloka maqhubu a fapaneng bakeng sa pheko e nepahetseng. Lisebelisuoa tse ling li ka hloka letoto le itseng la wavelengths e le hore li finyelle litšobotsi tse lakatsehang tsa ho folisa.

Substrate Compatibility:

The Pholiso ea LED ea UV  Sisteme e tlameha ho lumellana le substrate e phekolehang. Plastiki, tšepe le lirafshoa ke mehlala ea li-substrates tse nang le thepa e ka susumetsang mokhoa oa ho phekola. Mohlala, ho monya kapa ho khanya ha leseli la UV ke lisebelisoa tse itseng ho ka ama nako ea ho folisa kapa matla. Ho phethahatsa thepa e lakatsehang ea ho folisa, ho bohlokoa ho netefatsa hore sistimi ea pholiso ea UV LED e lumellana le karolo e ka tlase e phekolehang.

Bophelo ba Lebone:

Ha u khetha sesebelisoa sa ho bolaea likokoana-hloko tsa UV LED, ho bohlokoa ho nahana ka nako ea bophelo ba lebone. Nako ea bophelo ea lebone e ama litšenyehelo tsohle tsa botho ba sistimi, kaha ho nchafatsoa ha mabone khafetsa ho ka eketsa litšenyehelo tsohle. Nako ea bophelo ea lebone e ka fapana ho latela boleng ba lebone le ho sebelisoa hangata. Ho fokotsa litšenyehelo tsohle tsa botho, ho bohlokoa ho khetha lebone le tšoarellang, la boleng bo holimo la UV LED.

Boholo ba Tsamaiso:

Boholo ba   sisteme ea ho folisa ke ntlha ea bohlokoa hobane e ama sebaka sa ho kenya se hlokahalang. Ho ipapisitse le boholo ba thepa e phekolehang, lits'ebetso tse fapaneng li ka hloka litsamaiso tsa boholo bo fapaneng. Sistimi ea ho phekola matheba e sebelisoang indastering ea bongaka le ea meno e kanna ea ba nyane hape e baballa sebaka, athe lits'ebetso tsa ho phekola likhohola tse sebelisoang indastering ea likoloi li kanna tsa ba kholo mme tsa hloka sebaka se eketsehileng.

Litšenyehelo

Litšenyehelo tsa tsamaiso ea phekolo ke ntlha ea bohlokoa e lokelang ho nahanoa ha u khetha tsamaiso. Theko e kenyelletsa theko ea pele ea theko le litšenyehelo tsa ts'ebetso, joalo ka tšebeliso ea matla le mabone a ncha. Theko ea sistimi e ka fapana ho latela boleng ba sistimi le likarolo tsa eona. Ho bohlokoa ho khetha sistimi e bolokang chelete e lumellanang le litlhoko tse ikhethileng tsa kopo.

Likarolo tsa Sistimi e tsoetseng pele bakeng sa Pheko ea LED ea UV

Lisebelisoa tsa khatiso tsa UV LED

Khatiso ea UV LED ke lisebelisoa tsa ho phekola tse etselitsoeng ka ho khetheha bakeng sa lisebelisoa tsa khatiso. UV Lisebelisoa tsa khatiso tsa LED  sebelisa li-diode tsa UV tsa LED ho phekola mebala ea khatiso le liphahlo.

Litharollo tsa UV LED

Litharollo tsa UV LED  ba Pholiso ea LED ea UV litsamaiso tse reretsoeng ka kotloloho lits'ebetso tsa indasteri. Likopong tsa indasteri, U V LED tharollo Ba sebelisa li-diode tsa UV LED ho phekola lirafshoa, likhomaretsi le lintho tse ling.

Li-diode tsa UV LED ke likarolo tse ntšang mahlaseli a kotsi a UV ts'ebetsong ea ho phekola. Li-diode tsa UV LED li ntša leseli la UV ka har'a mefuta e 365-405 nm, e leng mofuta oa spectral o qalang mokhoa oa ho phekola.
