UltraViolet light absorbers akhala akudziwika kwa opanga pulasitiki, kwa nthawi ndithu, ngati chowonjezera chofunikira kuti ateteze mapulasitiki ku zotsatira zowonongeka za dzuwa.Ma infrared absorbers amadziwika ndi gulu laling'ono la opanga mapulasitiki.Komabe, pamene laser ikupeza kugwiritsa ntchito kowonjezereka gulu ili losadziwika la zowonjezera likuchulukira kugwiritsidwa ntchito.

Pamene ma lasers adakhala amphamvu kwambiri, chakumapeto kwa zaka za m'ma sikisite ndi koyambirira kwa zaka makumi asanu ndi awiri, zidawonekeratu kuti ogwiritsa ntchito laser ayenera kutetezedwa kukhungu la radiation ya infrared.Kutengera mphamvu, komanso kuyandikira kwa laser kwa diso, khungu lakanthawi kapena lokhazikika limatha kuchitika.Pafupifupi nthawi yomweyo, ndi malonda a polycarbonate, ma molders adaphunzira kugwiritsa ntchito zotsekemera za infrared m'mbale za zishango zakumaso za welder.Zatsopanozi zidapereka mphamvu zowongoka kwambiri, chitetezo ku radiation ya infrared komanso mtengo wotsika kuposa mbale zamagalasi zomwe zimagwiritsidwa ntchito panthawiyo.

Ngati wina akufuna kuletsa ma radiation onse a infrared, ndipo samakhudzidwa ndikuwona kudzera pa chipangizocho, amatha kugwiritsa ntchito mpweya wakuda.Komabe, ntchito zambiri zimafuna kufalitsa kuwala kowoneka bwino komanso kutsekereza mafunde a infrared.Ena mwa mapulogalamuwa ndi awa:

Zovala Zankhondo Zankhondo -Ma laser amphamvu amagwiritsidwa ntchito ndi asitikali kuti apeze mitundu yosiyanasiyana ndikuwona zida.Zanenedwa kuti panthawi ya nkhondo ya Iran - Iraq ya zaka makumi asanu ndi atatu, aku Iraq adagwiritsa ntchito laser rangefinder yamphamvu pa akasinja awo ngati chida chochititsa khungu mdani.Zamveka kuti mdani yemwe angakhalepo akupanga laser yamphamvu yoti igwiritsidwe ntchito ngati chida, cholinga chochititsa khungu asilikali a adani.Laser ya Neodynium/YAG imatulutsa kuwala pa 1064 nanometers (nm), ndipo imagwiritsidwa ntchito pofufuza zinthu zosiyanasiyana.Chifukwa chake, masiku ano asitikali amavala magalasi okhala ndi lens yopangidwa ndi polycarbonate yokhala ndi ma Infrared Absorbers amodzi kapena angapo, omwe amayamwa kwambiri pa 1064 nm, kuwateteza kuti asakumane ndi laser ya Nd/YAG.

Medical Eyewear - Zowonadi, ndikofunikira kuti asitikali azikhala ndi kuwala kowoneka bwino m'magalasi, omwe amaletsa ma radiation a infrared.Ndikofunikira kwambiri kuti ogwira ntchito zachipatala omwe amagwiritsa ntchito ma laser azikhala ndi kuwala kowoneka bwino, pomwe amatetezedwa kuti asakumane ndi ma laser omwe akugwiritsa ntchito.Chotsitsa cha infrared chomwe chasankhidwa chiyenera kulumikizidwa kuti chizitha kuyatsa kuwala kwamphamvu kwa laser yomwe imagwiritsidwa ntchito.Pamene kugwiritsidwa ntchito kwa lasers mu mankhwala kuchulukirachulukira, kufunika kwa chitetezo ku zotsatira zoyipa za radiation ya infrared kudzawonjezekanso.

Mimba Yankhope ya Welder ndi Goggles - Monga tafotokozera pamwambapa, iyi ndi imodzi mwazinthu zakale kwambiri za Infrared Absorbers.M'mbuyomu, makulidwe ndi mphamvu yakukhudzidwa kwa mbale yakumaso idanenedwa ndi muyezo wamakampani.Izi zinasankhidwa makamaka chifukwa chakuti ma infrared absorbers omwe ankagwiritsidwa ntchito panthawiyo amatha kuyaka ngati atakonzedwa pa kutentha kwakukulu.Pakubwera kwa ma Infrared Absorbers okhala ndi kukhazikika kwamafuta ambiri, zomwe zidasinthidwa chaka chatha kuti zilole zovala zamaso za makulidwe aliwonse.

Ogwira ntchito zamagetsi amayang'anizana ndi zishango - Ogwira ntchito za Electric Utility amatha kuwululidwa ndi ma radiation a infrared ngati pali kupindika kwa zingwe zamagetsi.Ma radiation amenewa amatha kuchititsa khungu, ndipo nthawi zina amakhala akupha.Zoteteza kumaso zokhala ndi zida zodzitetezera ku infrared zakhala zothandiza pochepetsa mavuto obwera chifukwa cha zina mwa ngozizi.M'mbuyomu, zishango za nkhope izi zidayenera kupangidwa ndi cellulose acetate propionate, chifukwa chotengera cha infrared chikanatha ngati polycarbonate itagwiritsidwa ntchito.Posachedwapa, chifukwa cha kubwera kwa zotengera zolimba kwambiri za infrared, zishango za nkhope za polycarbonate zikuyambitsidwa, zomwe zimapatsa antchitowa chitetezo chofunikira kwambiri.

Magalasi otsetsereka otsetsereka - Kuwala kwadzuwa komwe kumawonekera kuchokera ku matalala ndi ayezi kumatha kuchititsa khungu kwa otsetsereka.Kuwonjezera pa utoto, kuti tiunikire magalasi a galasi, ndi zoyatsira kuwala kwa ultraviolet kuti ziteteze ku kuwala kwa UVA ndi UVB, opanga ena tsopano akuwonjezera zosungunulira za infrared kuti ateteze ku zotsatira zovulaza za cheza cha infrared.

Palinso ntchito zina zambiri zosangalatsa zogwiritsa ntchito zida zapadera za ma infrared absorbers.Izi zikuphatikiza mbale zosindikizira za laser ablated lithographic, kuwotcherera kwa laser filimu yapulasitiki, zotsekera zotchingira, ndi inki zachitetezo.

Magulu atatu akuluakulu a mankhwala omwe amagwiritsidwa ntchito ngati ma infrared absorbers ndi cyanines, aminium salt ndi dithiolenes zitsulo.Ma cyanines ndi mamolekyu ang'onoang'ono motero alibe kukhazikika kwamafuta kuti agwiritsidwe ntchito mu polycarbonate yowumbidwa.Mchere wa amininium ndi mamolekyu akuluakulu ndipo ndi olimba kwambiri kuposa ma cyanines.Zatsopano mu chemistry iyi zawonjezera kutentha kwapamwamba kwa zotengera izi kuchokera pa 480oF kufika pa 520oF.Kutengera chemistry ya mchere wa aminium, izi zimatha kukhala ndi mawonekedwe a infrared, omwe amayambira otakata kwambiri mpaka opapatiza.Ma dithiolenes achitsulo ndi okhazikika kwambiri, koma amakhala ndi vuto lokwera mtengo kwambiri.Ena ali ndi mawonekedwe a mayamwidwe, omwe ndi opapatiza kwambiri.Ngati sanapangidwe bwino, dithiolenes zachitsulo zimatha kutulutsa fungo loyipa la sulfure panthawi yokonza.

Makhalidwe a ma infrared absorbers, omwe ali ofunikira kwambiri ku ma polycarbonate molders, ndi awa:

Kukhazikika kwa Matenthedwe - kusamala kwambiri kuyenera kutengedwa popanga ndi kukonza polycarbonate yokhala ndi zotengera zamchere zamchere za amininium.Kuchuluka kwa choyezera chomwe chikufunika kuti chitsekereze kuchuluka kwa ma radiation kuyenera kuwerengedwa poganizira makulidwe a mandala.The pazipita kukhudzana kutentha ndi nthawi ayenera anatsimikiza ndi mosamalitsa.Ngati chotsitsa cha infrared chikhalabe mu makina opangira "nthawi yopuma ya khofi", chotsitsacho chidzawotchedwa ndipo zidutswa zoyamba zomwe zimapangidwira pambuyo popuma zidzakanidwa.Zina zomwe zangopangidwa kumene za mchere wa amininium mchere wa infuraredi walola kutentha kwakukulu kotetezedwa kuti kuchuluke kuchoka pa 480oF kufika pa 520oF, potero kuchepetsa chiwerengero cha ziwalo zokanidwa chifukwa cha kutentha.

Mayamwidwe - ndi muyeso wa infrared kutsekereza mphamvu ya absorber pa yuniti ya kulemera, pa wavelength inayake.The apamwamba mayamwidwe, mphamvu kutsekereza kwambiri.Ndikofunikira kuti ogulitsa ma infrared absorber akhale ndi kusinthasintha kwa batch-to-batch ya mayamwidwe.Ngati sichoncho, mudzakhala mukupanganso ndi gulu lililonse la absorber.

Visible Light Transmission (VLT) - Nthawi zambiri mumafuna kuchepetsa kufala kwa kuwala kwa infrared, kuchokera pa 800 nm mpaka 2000nm, ndikukulitsa kufalikira kwa kuwala kowoneka kuchokera 450nm mpaka 800nm.Diso la munthu limakhudzidwa kwambiri ndi kuwala kudera la 490nm mpaka 560nm.Tsoka ilo, zotengera zonse zopezeka ndi infrared zimatenga kuwala kowoneka komanso kuwala kwa infrared, ndikuwonjezera mtundu wina, nthawi zambiri wobiriwira pagawo lopangidwa.

Chifunga - Chokhudzana ndi Kutumiza Kuwala Kowoneka, chifunga ndi chinthu chofunikira kwambiri pazovala zamaso chifukwa chimatha kuchepetsa kwambiri mawonekedwe.Ubweya ukhoza kuyambitsidwa ndi zosafunika mu IR Dye, zomwe sizimasungunuka mu polycarbonate.Mitundu yatsopano ya aminium IR imapangidwa m'njira yoti zonyansazi zichotsedweratu, motero zimachotsa chifunga chochokera ku gwero lino, ndikupangitsa kuti kutentha kukhazikike.

Zogulitsa Zotsogola ndi Ubwino Wotsogola - Kusankha koyenera kwa Infrared Absorbers, kumalola purosesa ya mapulasitiki kuti apereke zinthu zokhala ndi magwiridwe antchito abwino komanso apamwamba kwambiri nthawi zonse.

Popeza ma infrared absorbers ndi okwera mtengo kwambiri kuposa zowonjezera zina za pulasitiki ($/gram m'malo mwa $/lb), ndikofunikira kwambiri kuti wopanga azisamala kwambiri kuti akonze bwino kuti apewe kuwononga, komanso kuti akwaniritse zofunikira.Ndikofunikiranso kuti purosesayo akhazikitse mosamala mikhalidwe yofunikira kuti apewe kupanga zinthu zina.Itha kukhala ntchito yovuta, koma imatha kubweretsa zinthu zamtengo wapatali zowonjezera.
