Ama-absorber okukhanya e-UltraViolet aziwa ngabakhi bepulasitiki, isikhathi eside, njengesengezo esidingekayo ukuze kuvikelwe amapulasitiki emiphumeleni yesikhathi eside eyonakalisayo yokukhanya kwelanga.Ama-absorber e-infrared aziwa kuphela eqenjini elincane labaklami bepulasitiki.Kodwa-ke, njengoba i-laser ithola ukusetshenziswa okwandayo leli qembu elingaziwa lezithasiselo liyakhula ngokusetshenziswa.

Njengoba ama-laser eba namandla kakhulu, ngasekupheleni kweminyaka yama-60 nasekuqaleni kwawo-70, kwaba sobala ukuthi ama-laser opharetha kufanele avikelwe emthelela wokuphuphuthekisa wemisebe ye-infrared.Kuye ngamandla, kanye nokuba seduze kwe-laser esweni, kungaba ubumpumputhe besikhashana noma unomphela.Cishe ngesikhathi esifanayo, ngokudayiswa kwe-polycarbonate, ababumba bafunda ukusebenzisa izinto ezimunca infrared kumapuleti ezivikelo zobuso ze-welder.Lokhu okusha kunikeze amandla omthelela aphezulu, ukuvikeleka emisebeni ye-infrared kanye nezindleko eziphansi kunamapuleti engilazi ayesetshenziswa ngaleso sikhathi.

Uma umuntu efuna ukuvimba yonke imisebe ye-infrared, futhi engakhathazeki ngokubona ngomshini, angasebenzisa i-carbon black.Kodwa-ke, izinhlelo zokusebenza eziningi zidinga ukudluliswa kokukhanya okubonakalayo kanye nokuvimbela amaza amaza e-infrared.Ezinye zalezi zicelo zihlanganisa:

Izingubo Zamehlo Zezempi -Ama-laser anamandla asetshenziswa amasosha ukuthola uhla nokubona izikhali.Kuye kwabikwa ukuthi phakathi nempi yase-Iran - Iraq yeminyaka engamashumi ayisishiyagalombili, ama-Iraqi asebenzisa isitholi selaser esinamandla emathangini abo njengesikhali sokuphuphuthekisa isitha.Kuye kwaba namahemuhemu okuthi umuntu okungenzeka abe yisitha sakhe i-laser enamandla ezosetshenziswa njengesikhali, esihloselwe ukuvala amehlo amasosha ezitha.I-laser ye-Neodynium/YAG ikhipha ukukhanya ku-1064 nanometers (nm), futhi isetshenziselwa ukuthola ububanzi.Ngakho-ke, namuhla amasosha agqoka izibuko ezinelensi ye-polycarbonate ebunjiwe ehlanganisa i-Infrared Absorbers eyodwa noma ngaphezulu, emunca kakhulu ku-1064 nm, ukuze awavikele ekuchayekeni okungazelelwe ngele-Nd/YAG laser.

I-Medical Eyewear - Impela, kubalulekile ukuthi amasosha abe nokudluliswa kokukhanya okuhle okubonakalayo ezibuko, ezivimba i-Infrared Radiation.Kubaluleke nakakhulu ukuthi abasebenzi bezokwelapha abasebenzisa amalaser babe nokudluliswa kokukhanya okuhle kakhulu okubonakalayo, kuyilapho bevikelekile ekuchayekeni ngengozi kuma-laser abawasebenzisayo.Isibambisi se-infrared esikhethiwe kufanele sihlanganiswe ukuze sibambe ukukhanya kubude begagasi bokuphuma kwelaser esetshenzisiwe.Njengoba ukusetshenziswa kwama-lasers kwezokwelapha kukhula, isidingo sokuvikelwa emiphumeleni eyingozi yemisebe ye-infrared sizokhula.

I-Welder's Face Plates and Goggles - Njengoba kushiwo ngenhla, lesi esinye sezinhlelo zokusebenza ezindala kakhulu ze-Infrared Absorbers.Esikhathini esidlule, ukujiya namandla okuthonya kwe-face plate kwakucaciswe yizinga lemboni.Lokhu kucaciswa kukhethwe ngokuyinhloko ngenxa yokuthi izibambisi ze-infrared ezazisetshenziswa ngaleso sikhathi zizosha uma zicutshungulwa ezingeni lokushisa eliphezulu.Ngokufika kwama-Infrared Absorbers anokuqina okukhulu kwe-thermal, ukucaciswa kwashintshwa ngonyaka odlule ukuze kuvumele izingubo zamehlo zanoma yikuphi ukushuba.

Izisebenzi zikagesi zibhekene nezihlangu - Izisebenzi ze-Electric Utility zingavezwa emisebeni eqinile ye-infrared uma kukhona i-arcing yezintambo zikagesi.Le misebe ingaphuphuthekisa, futhi kwezinye izimo iye yabulala.Izivikelo zobuso ezihlanganisa izinto ezimunca infrared ziye zaba usizo ekwehliseni imiphumela edabukisayo yezinye zalezi zingozi.Esikhathini esedlule, lezi zihlangu zobuso bekufanele zenziwe nge-cellulose acetate propionate, ngoba i-infrared absorber yayizosha uma kusetshenziswa i-polycarbonate.Muva nje, ngenxa yokufika kwezimunyisi ze-infrared ezinze kakhulu, kwethulwa izihlangu zobuso ze-polycarbonate, ezihlinzeka laba basebenzi ngokuvikelwa komthelela okuphezulu okudingekayo.

Izibuko ezisezingeni eliphezulu zokushushuluza - Ukukhanya kwelanga okuvela eqhweni naseqhweni kungaba nomthelela ongemuhle kwabashushuluzi.Ngaphezu kodayi, ukufinyamisa izibuko, nezinto ezimunca ukukhanya kwe-ultraviolet ukuze zivikeleke emisebeni ye-UVA ne-UVB, abanye abakhiqizi manje sebengeza izinto ezimunca infrared ukuze bavikele emiphumeleni eyingozi yemisebe ye-infrared.

Ziningi ezinye izinhlelo zokusebenza ezithokozisayo ezisebenzisa izakhiwo ezikhethekile zokumunca infrared.Lokhu kuhlanganisa amapuleti okuphrinta e-laser ablated lithographic, i-laser welding yefilimu yepulasitiki, izivalo zokukhanya, noyinki wokuphepha.

Amaqembu amathathu amakhulu amakhemikhali asetshenziswa njengezinqamuleli ze-infrared yi-cyanines, usawoti we-aminium kanye ne-dithiolenes yensimbi.Ama-cyanines angama-molecule amancane ngakho-ke awanakho ukuzinza okushisayo okuzosetshenziswa ku-polycarbonate ebunjiwe.Usawoti we-amininium ungama-molecule amakhulu futhi azinzile ngokushisa kakhulu kunama-cyanines.Intuthuko entsha kule chemistry inyuse izinga lokushisa eliphezulu lalezi zinto ezimuncayo ukusuka ku-480oF kuya ku-520oF.Ngokuya ngekhemikhali yosawoti we-aminium, lezi zingaba ne-infrared absorption spectra, esukela ebanzi kakhulu iye emincane kakhulu.Ama-dithiolenes ensimbi yiwona azinze kakhulu ngokushisa, kodwa anesimo esibi sokumba eqolo.Abanye bane-spectra yokumuncwa, emincane kakhulu.Uma ingahlanganiswa kahle, i-dithiolenes yensimbi ingakhipha iphunga elibi lesulfure ngesikhathi sokucubungula.

Izakhiwo ze-infrared absorbers, ezibaluleke kakhulu kuma-polycarbonate molders, yilezi:

Ukuzinza Kwe-Thermal - ukunakekelwa okukhulu kufanele kuthathwe ekuhlanganiseni nasekucubunguleni i-polycarbonate equkethe ama-absorber e-infrared kasawoti we-aminium.Inani le-absorber elidingekayo ukuze kuvinjwe inani elifunekayo lemisebe kufanele libalwe kucatshangelwa ukushuba kwelensi.Izinga lokushisa eliphezulu lokuchayeka kanye nesikhathi kufanele kunqunywe futhi kubhekwe ngokucophelela.Uma i-absorber ye-infrared ihlala emshinini wokubumba ngesikhathi "sokuphumula kwekhofi esandisiwe", i-absorber izoshisa futhi izingcezu ezimbalwa zokuqala ezibunjiwe ngemva kwekhefu zizonqatshwa.Amanye ama-absorber e-infrared kasawoti e-amininium asanda kwakhiwa avumele izinga lokushisa eliphakeme eliphephile lokubumba ukuba linyuswe lisuka ku-480oF liye ku-520oF, ngaleyo ndlela linciphise inani lezingxenye ezinqatshiwe ngenxa yokusha.

I-Absorptivity - isilinganiso samandla okuvimbela i-infrared we-absorber ngeyunithi ngayinye yesisindo, kubude obuthile.Ukuphakama kokumuncwa, amandla okuvimbela ngaphezulu.Kubalulekile ukuthi umhlinzeki we-infrared absorber abe nokuvumelana okuhle kwe-batch-to-batch yokumuncwa.Uma kungenjalo, uzobe wenza kabusha ngeqoqo ngalinye lesinqamuleli.

I-Visible Light Transmission (VLT) - Ezinhlelweni eziningi ufuna ukunciphisa ukudluliswa kokukhanya kwe-infrared, ukusuka ku-800 nm kuya ku-2000nm, futhi wandise ukudluliswa kokukhanya okubonakalayo kusuka ku-450nm kuya ku-800nm.Iso lomuntu lizwela kakhulu ekukhanyeni endaweni ye-490nm kuya ku-560nm.Ngeshwa wonke ama-absorber we-infrared atholakalayo amunca ukukhanya okubonakalayo kanye nokukhanya kwe-infrared, bese engeza umbala othile, ngokuvamile oluhlaza engxenyeni ebunjiwe.

I-Haze - Ihlobene Nokudluliswa Kokukhanya Okubonakalayo, inkungu iyimpahla ebalulekile emigqonyeni yamehlo njengoba inganciphisa kakhulu ukubonakala.Uboya bungabangelwa ukungcola okuku-IR Dye, okungancibiliki ku-polycarbonate.I-aminium IR Dyes entsha ikhiqizwa ngendlela yokuthi lokhu kungcola kususwe ngokuphelele, ngaleyo ndlela kuqedwe inkungu kulo mthombo, futhi kwaqondana nokuthuthukisa ukuqina okushisayo.

Imikhiqizo Ethuthukisiwe Nekhwalithi Ethuthukisiwe - Ukukhetha okulungile kwama-Infrared Absorbers, kuvumela iphrosesa yepulasitiki ukuthi inikeze imikhiqizo enezici zokusebenza ezithuthukisiwe nezisezingeni eliphezulu ngokungaguquki.

Njengoba izithasiselo ze-infrared zibiza kakhulu kunezinye izithasiselo zepulasitiki ($/gram esikhundleni se-$/lb), kubaluleke kakhulu ukuthi umenzi wefomula aqikelele kakhulu ukuze akhe ngokunembayo ukuze agweme ukumosha, kanye nokuzuza ukusebenza okudingekayo.Kubaluleke ngokufanayo ukuthi iphrosesa ithuthukise ngokucophelela izimo zokucubungula ezidingekayo ukuze igweme ukukhiqiza imikhiqizo engaphandle kwe-spec.Kungaba umsebenzi oyinselele, kodwa kungaholela emikhiqizweni yekhwalithi enenani eliphezulu.
