I-UltraViolet i-absorbers yokukhanya iye yaziwa kwii-formulators zeplastiki, ixesha elithile, njengezongezo eziyimfuneko ukukhusela iiplastiki kwimiphumo yexesha elide elibi lokukhanya kwelanga.I-absorber ye-infrared iye yaziwa kuphela kwiqela elincinci le-formulators zeplastiki.Nangona kunjalo, njengoko i-laser ifumana usetyenziso olwandisiweyo eli qela lingaziwayo lezongezo liyakhula ngokusetyenziswa.
Njengoko iilaser ziye zaba namandla ngakumbi, ekupheleni kweminyaka engamashumi amathandathu kunye nasekuqaleni kweminyaka engamashumi asixhenxe, kwaye kwacaca ukuba abaqhubi belaser kufuneka bakhuselwe kwisiphumo esimfamekisayo semitha ye-infrared.Ngokuxhomekeke kumandla, kunye nokusondela kwelaser kwiliso, nokuba yimfama yethutyana okanye esisigxina.Malunga nexesha elifanayo, ngokurhweba kwepolycarbonate, ababumbi bafunda ukusebenzisa i-infrared absorbers kwiiplate zokukhusela ubuso be-welder.Olu tshintsho lunikeze amandla empembelelo ephezulu, ukukhuselwa kwimitha ye-infrared kunye neendleko eziphantsi kuneepleyiti zeglasi ezazisetyenziswa ngelo xesha.
Ukuba umntu wayefuna ukuvimba yonke imisebe ye-infrared, kwaye wayengakhathazeki ngokubona ngesixhobo, umntu unokusebenzisa i-carbon black.Nangona kunjalo, izicelo ezininzi zifuna ukuhanjiswa kokukhanya okubonakalayo kunye nokuthintela i-infrared wavelengths.Ezinye zezi zicelo ziquka:
Impahla yamehlo yasemkhosini-Iilaser ezinamandla zisetyenziswa ngumkhosi ukufumana uluhlu kunye nokubona izixhobo.Kuye kwaxelwa ukuba ngexesha le-Iran - imfazwe yase-Iraq yeminyaka yamashumi asibhozo, ama-Iraqi asebenzisa i-laser range ye-laser enamandla kwiitanki zabo njengesixhobo sokumfamekisa utshaba.Kuye kwavakala ukuba utshaba olunokubakho luphuhlisa i-laser enamandla ukuze isetyenziswe njengesixhobo, esijoliswe ukumfamekisa imikhosi yotshaba.I-laser ye-Neodynium / YAG ikhupha ukukhanya kwi-1064 nanometers (nm), kwaye isetyenziselwa ukufumana uluhlu.Ngenxa yoko, namhlanje amajoni anxiba iiglasi ezinelensi yepolycarbonate ebunjiweyo ebandakanya enye okanye ngaphezulu kwe-Infrared Absorbers, efunxa kakhulu kwi-1064 nm, ukubakhusela ekuvezweni ngengozi kwi-laser ye-Nd/YAG.
I-Medical Eyewear - Ngokuqinisekileyo, kubalulekile ukuba amajoni abe nokuhanjiswa kokukhanya okubonakalayo kakuhle kwiiglasi, ezivimba i-Infrared Radiation.Kubaluleke ngakumbi ukuba abasebenzi bezonyango abasebenzisa iilaser banokuhanjiswa kokukhanya okubonakalayo okugqwesileyo, ngelixa bekhuselwe ekuvezweni ngengozi kwiilaser abazisebenzisayo.I-absorber ye-infrared ekhethiweyo kufuneka ilungelelaniswe ukwenzela ukuba ithathe ukukhanya kwi-wavelength yokukhutshwa kwe-laser esetyenzisiweyo.Njengoko ukusetyenziswa kwe-laser kumayeza kusanda, imfuno yokhuseleko kwimiphumo eyingozi yemitha ye-infrared nayo iya kwanda.
Iipleyiti zobuso be-Welder kunye neeGoggles - Njengoko kukhankanyiwe ngasentla, le yenye yezona zicelo zakudala ze-Infrared Absorbers.Ngaphambili, ubukhulu kunye namandla empembelelo ye-face plate ichazwe ngumgangatho woshishino.Le ngcaciso ikhethwe ngokuyinhloko kuba i-infrared absorbers esetyenziswe ngelo xesha iya kutsha xa iqhutywe kwiqondo lokushisa eliphezulu.Ngokufika kwe-Infrared Absorbers kunye nokuzinza okukhulu kwe-thermal, ukucaciswa kwatshintshwa kunyaka ophelileyo ukuze kuvumeleke i-eyewear nayiphi na ingqimba.
Abasebenzi bombane bajongene nezikhuselo - Abasebenzi be-Electric Utility banokuvezwa kwi-radiation ebukhali ye-infrared ukuba kukho i-arcing yeentambo zombane.Le mitha inokumfamekisa, kwaye kwezinye iimeko iye yabulala.Izikhuselo zobuso ezibandakanya i-infrared absorbers ziye zaba luncedo ekunciphiseni imiphumo ebuhlungu yezinye zezi ngozi.Ngaphambili, ezi zikhuselo zobuso kwakufuneka zenziwe nge-cellulose acetate propionate, kuba i-absorber ye-infrared iya kutshisa ukuba i-polycarbonate isetyenziswe.Kutshanje, ngenxa yokuvela kwezixhobo zokufunxa ze-infrared ezizinzile ngokushushu, izikhuselo zobuso ze-polycarbonate ziyaziswa, zibonelela aba basebenzi ngokhuseleko olufunekayo oluphezulu.
Iiglasi eziphakamileyo zokutyibiliza - Ukukhanya kwelanga okubonakaliswa kwikhephu kunye nomkhenkce kunokuba nefuthe elimfamekisayo kubatyibilizi.Ukongezelela kwidayi, ukwenza itint izibuko, nezinto ezifunxa ukukhanya kweultraviolet ukuze zikhuseleke kwimitha ye-UVA neUVB, ngoku abanye abavelisi bongeza izinto zokufunxa iinfrared ukuze zikhuseleke kwimiphumo eyingozi yemitha yeinfrared.
Zininzi ezinye izicelo ezinomdla ezisebenzisa iipropathi ezikhethekileyo ze-infrared absorbers.Ezi zibandakanya iipleyiti zoshicilelo ze-laser ablated lithographic, ukuwelda ngelaser yefilimu yeplastiki, izivalo zokukhanya, kunye nee-inki zokhuseleko.
Amaqela amathathu amakhulu emichiza asetyenziswa njengezinto zokufunxa infrared ziicyanines, iityuwa zeaminium kunye needithiolenes zentsimbi.I-cyanines ziimolekyuli ezincinci kwaye ke ngoko azinalo uzinzo lwe-thermal olunokusetyenziswa kwipolycarbonate ebunjiweyo.Iityuwa ze-amininium ziimolekyuli ezinkulu kwaye zizinzile ngokushushu ngakumbi kuneecyanines.Uphuhliso olutsha kule khemistry lunyuse ubushushu obuphezulu bokubumba ezi zinto zithatha ukusuka kwi-480oF ukuya kwi-520oF.Ngokuxhomekeke kwikhemikhali yeetyuwa ze-aminium, ezi zinokuba ne-infrared absorption spectra, ukusuka kububanzi ukuya kumxinwa.I-metal dithiolenes zezona zizinzile ngokwe-thermal, kodwa zine-advantvantji yokubiza kakhulu.Abanye banembonakalo yokufunxa, ecuthe kakhulu.Ukuba ayilungiswanga ngokufanelekileyo, i-dithiolenes yensimbi inokukhupha ivumba elibi lesulfure ngexesha lokucubungula.
Iimpawu ze-infrared absorbers, ezibaluleke kakhulu kwii-polycarbonate molders, zezi:
Ukuzinza kweThermal - kufuneka kuthathelwe ingqalelo enkulu ekuqulunqeni nasekuqhubeni i-polycarbonate equlethe i-absorber ye-infrared yetyuwa ye-aminium.Ubungakanani besixhobo sokufunxa esifunekayo ukuvala ubungakanani obufunwayo bemitha yemitha kufuneka sibalwe ngokuqwalasela ubukhulu belensi.Ubushushu obuphezulu bokuvezwa kunye nexesha kufuneka limiselwe kwaye liqwalaselwe ngononophelo.Ukuba i-absorber ye-infrared ihlala kumatshini wokubumba ngexesha "lokuphumla kwekhofi eyandisiweyo", i-absorber iya kutshisa kwaye iziqwenga zokuqala ezibunjiweyo emva kokuphuka ziya kunqatshwa.Ezinye ezisanda kuphuhliswa i-amininium ityuwa ye-infrared absorbers ziye zavumela ubushushu obuphezulu obukhuselekileyo bokubumba ukuba bunyuswe ukusuka kwi-480oF ukuya kwi-520oF, ngokunciphisa inani leendawo ezikhatywayo ngenxa yokutsha.
I-Absorptivity - ngumlinganiselo wamandla okuthintela i-infrared ye-absorber kwiyunithi nganye yobunzima, kwi-wavelength ethile.Ukuphakama kokufunxa, kokukhona amandla okuthintela.Kubalulekile ukuba umthengisi we-infrared absorber abe nebhetshi ukuya kwibhetshi ehambelanayo yokufunxa.Ukuba akunjalo, uya kube uqulunqa kwakhona ngebhetshi nganye yesithambiso.
Ukuhanjiswa kokukhanya okubonakalayo (VLT) - Kwizicelo ezininzi ufuna ukunciphisa ukuhanjiswa kokukhanya kwe-infrared, ukusuka kwi-800 nm ukuya kwi-2000nm, kwaye ukwandise ukuhanjiswa kokukhanya okubonakalayo ukusuka kwi-450nm ukuya kwi-800nm.Iliso lomntu libukhali kakhulu ekukhanyeni kummandla we-490nm ukuya kwi-560nm.Ngelishwa zonke ii-absorber ze-infrared ezikhoyo zifunxa ukukhanya okubonakalayo kunye nokukhanya kwe-infrared, kwaye zongeze umbala othile, odla ngokuba luhlaza kwindawo ebunjiweyo.
I-Haze-Iyayamene nokuhanjiswa kokukhanya okubonakalayo, inkungu yinto ebalulekileyo kwimpahla yamehlo njengoko inokunciphisa kakhulu ukubonakala.Inkungu inokubangelwa bubumdaka be-IR Dayi, enganyibilikiyo kwipolycarbonate.I-aminium entsha ye-IR Dyes iveliswa ngendlela yokuba obu kungcola bususwe ngokupheleleyo, ngaloo ndlela kupheliswe inkungu kulo mthombo, kwaye ngengozi kuphuculwe ukuzinza kwe-thermal.
IiMveliso eziPhuculweyo kunye noMgangatho oPhuculweyo - Ukhetho oluchanekileyo lwe-Infrared Absorbers, luvumela iprosesa yeplastiki ukuba ibonelele ngeemveliso eziphuculweyo zokusebenza kunye nezinga eliphezulu elihlala liphezulu.
Njengoko i-absorber ye-infrared ibiza kakhulu kunezinye izongezo zeplastiki (i-$/gram endaweni ye-$ / lb), kubaluleke kakhulu ukuba umenzi wefomula athathele ingqalelo enkulu ukuyila ngokuchanekileyo ukuphepha inkunkuma, kunye nokuzuza ukusebenza okufunekayo.Kubalulekile ngokulinganayo ukuba iprosesa iphuhlise ngononophelo iimeko eziyimfuneko zokuqhuba ukuthintela ukuvelisa iimveliso ezingaphandle.Ingangumsebenzi onzima, kodwa inokuba nesiphumo somgangatho ophezulu wokongezwa kweemveliso.
