UltraViolet mwenje inopinza yave ichizivikanwa kune epurasitiki formulator, kwenguva yakati, sechinhu chinodiwa chekuwedzera kuchengetedza mapurasitiki kubva kune yakarebesa mhedzisiro yezuva.Infrared absorbers yave ichizivikanwa chete kune boka diki remapurasitiki ekugadzira.Nekudaro, sezvo iyo laser inowana yakawedzera application iri boka risingazivikanwe rekuwedzera riri kuwedzera mukushandiswa.

Sezvo lasers akawedzera simba, mukupera kwamakumi matanhatu uye kutanga makumi manomwe, zvakava pachena kuti laser opareta anofanirwa kuchengetedzwa kubva pakupofumadza maitiro eiyo infrared radiation.Zvichienderana nesimba, uye padyo nelaser paziso, kungave kwechinguvana kana upofu hwechigarire hunogona kuguma.Panenge panguva imwe chete, nekutengeserana kwepolycarbonate, molders vakadzidza kushandisa infrared absorbers mumaplate ezvivharo zvechiso chewelder.Iyi innovation yakapa yakakwirira simba simba, dziviriro kubva kune infrared radiation uye yakaderera mutengo pane magirazi egirazi aishandiswa panguva iyoyo.

Kana munhu aida kuvharidzira ese infrared radiation, uye asina hanya nekuona kuburikidza nemudziyo, munhu aigona kushandisa kabhoni dema.Nekudaro, akawanda maapplication anoda kutapurirana kwechiedza chinooneka pamwe nekuvharira infrared wavelengths.Zvimwe zvezvikumbiro izvi zvinosanganisira:

Military Eyewear -Malaser ane simba anoshandiswa nemauto kutsvaga uye kuona zvombo.Zvinonzi panguva yehondo yeIran-Iraq yemakumi masere, maIraq akashandisa ine simba laser range finder pamatangi avo sechombo chekupofumadza muvengi.Kwave nerunyerekupe rwekuti muvengi angangove ari kugadzira laser ine simba kuti ishandiswe sechombo, chinangwa chekupofumadza mauto evavengi.Iyo Neodynium/YAG laser inoburitsa mwenje pa1064 nanometers (nm), uye inoshandiswa pakutsvaga kwemhando.Nekuda kweizvozvo, nhasi masoja anopfeka magogi ane yakaumbwa polycarbonate lens inobatanidza imwe kana anopfuura maInfrared Absorbers, ayo anonyudza zvakanyanya pa1064 nm, kuvadzivirira kubva pakusangana neNd/YAG laser.

Medical Eyewear - Chokwadi, zvakakosha kuti masoja ave neakanaka anooneka mwenje kutapurirana mumagirazi, ayo anovhara Infrared Radiation.Izvo zvakatonyanya kukosha kuti vashandi vekurapa vanoshandisa lasers vave neakanakisa mwenje wekutapurirana, uku vachidzivirirwa kubva pakusangana nekusarudzika kune lasers yavari kushandisa.Iyo infrared absorber yakasarudzwa inofanirwa kurongeka kuitira kuti itore mwenje pawavelength yekubuda kwelaser inoshandiswa.Sezvo kushandiswa kwema lasers mukurapa kunowedzera, kudiwa kwekudzivirirwa kubva kune zvinokuvadza zve infrared radiation kuchawedzerawo.

Welder's Face Plates uye Goggles - Sezvataurwa pamusoro apa, iyi ndeimwe yekare kushandiswa kweInfrared Absorbers.Kare, ukobvu uye kusimba kwesimba kwechiso chendiro kwakatsanangurwa neyakajairwa indasitiri.Iyi rondedzero yakasarudzwa zvakanyanya nekuti infrared absorbers yaishandiswa panguva iyoyo yaizotsva kana ikagadziriswa patembiricha yepamusoro.Nekuuya kweInfrared Absorbers ine kugadzikana kwakanyanya kwekupisa, iyo yakatarwa yakashandurwa gore rapfuura kuti ibvumire maziso ehukobvu chero hupi.

Vashandi vemagetsi vanotarisana nenhovo - Vashandi veMagetsi Utility vanogona kuoneswa kune yakanyanya infrared radiation kana paine arcing yetambo dzemagetsi.Mwaranzi iyi inogona kupofumadza, uye mune dzimwe nguva yave ichiuraya.Zvidziviriro zvechiso zvinosanganisira zvinobatisa infrared zvave zvichibatsira mukuderedza nhamo dzedzimwe tsaona idzi.Munguva yakapfuura, idzi nhovo dzechiso dzaifanira kugadzirwa ne cellulose acetate propionate, nokuti infrared absorber yaizopisa kana polycarbonate yakashandiswa.Nguva pfupi yadarika, nekuda kwekuuya kweakanyanya kudzikama infrared absorbers, polycarbonate face shields dziri kuunzwa, zvichipa vashandi ava dziviriro inodiwa yepamusoro.

High end skiing goggles - Chiedza chezuva chinoratidzwa kubva kuchando nechando chinogona kupofumadza kune vanotsvedza.Kuwedzera kudhayi, kupinza magirazi egirazi, uye zvinobatisa chiedza cheultraviolet kudzivirira kubva kumwaranzi yeUVA neUVB, vamwe vagadziri vave kuwedzera zvinobatisa infrared kudzivirira pakukuvadza kwemwaranzi ye infrared.

Kune mamwe akawanda anonakidza maapplication anoshandisa akakosha zvivakwa zve infrared absorbers.Izvi zvinosanganisira laser ablated lithographic printing plates, laser welding yepurasitiki firimu, optical shutters, uye inki dzekuchengetedza.

Mapoka matatu makuru emakemikari anoshandiswa se infrared absorbers ndeye cyanines, aminium munyu uye dithiolenes simbi.Iwo ma cyanines ari mamorekuru madiki saka saka haana kugadzikana kwekupisa kunoshandiswa mu polycarbonate yakaumbwa.Aminium salts mamorekuru akakura uye anogadzikana zvakanyanya kupfuura macyanines.Zvitsva zviri kuitika mukemikari iyi zvakawedzera tembiricha yekuumba yezvinwiwa izvi kubva pa480oF kusvika pa520oF.Zvichienderana nekemikari yeaminium munyu, aya anogona kunge ane infrared absorption spectra, iyo inotangira pahupamhi kusvika pakutetepa.Iyo dithiolenes yesimbi ndiyo yakanyanya kugadzikana inopisa, asi ine dhizaini yekudhura zvakanyanya.Vamwe vane absorption spectra, ayo akamanikana kwazvo.Kana isina kugadzirwa zvakanaka, simbi dithiolenes inogona kupa kunhuhwirira kwakashata kwesarufa panguva yekugadzirisa.

Izvo zvimiro zve infrared absorbers, izvo zvakanyanya kukosha kune polycarbonate molders, ndezvi:

Thermal Kugadzikana - kungwarira kukuru kunofanirwa kutorwa mukugadzira uye kugadzirisa polycarbonate ine aminium munyu infrared absorbers.Huwandu hwemucherechedzo unodiwa kudzivirira huwandu hunodiwa hwemwaranzi hunofanirwa kuverengerwa tichitarisa ukobvu hwelens.Iyo yakanyanya kuratidzwa tembiricha uye nguva inofanirwa kutariswa uye kunyatsocherechedzwa.Kana iyo infrared absorber inoramba iri mumushini wekuumba panguva ye "yakawedzerwa kofi break", iyo inopinza ichapisa uye zvimedu zvekutanga zvakaumbwa mushure mekuputika zvicharambwa.Mamwe achangobva kugadzirwa aminium munyu infrared absorbers akabvumira yakanyanya kuchengetedzeka tembiricha yekuumbwa kuti iwedzere kubva pa480oF kusvika 520oF, nekudaro ichidzikisa huwandu hwezvikamu zvakarambwa nekuda kwekutsva.

Absorptivity - ndiyo chiyero che infrared blocking simba remucherechedzo payuniti yehuremu, pane imwe wavelength.Iyo yakakwirira iyo absorptivity, iyo inowedzera kuvhara simba.Izvo zvakakosha kuti mutengesi we infrared absorber ave akanaka batch-to-batch kuenderana kwekunyura.Kana zvisina kudaro, iwe unenge uchigadzirisa nebatch yega yega yekunyudza.

Inooneka Mwenje Transmission (VLT) - Mumaapplication mazhinji iwe unoda kudzikisira kutapurirana kwechiedza che infrared, kubva pa800 nm kusvika 2000nm, uye kuwedzera mwenje unooneka kubva pa450nm kusvika 800nm.Ziso remunhu rinonyanya kunzwa chiedza munharaunda ye490nm kusvika 560nm.Sezvineiwo ese anowanikwa infrared absorbers anotora chiedza chinooneka pamwe nemwenje infrared, uye wedzera rumwe ruvara, kazhinji girinhi kune yakaumbwa chikamu.

Haze - Yakabatana neInooneka Chiedza Kufambiswa, mhute chinhu chakakosha muhembe dzemaziso sezvo ichigona kuderedza zvakanyanya kuoneka.Haze inogona kukonzerwa nekusachena muIR Dye, iyo isinganyungudika mu polycarbonate.Iyo mitsva aminium IR Dyes inogadzirwa nenzira yekuti tsvina iyi ibviswe zvachose, nekudaro kubvisa haze kubva kune ino sosi, uye zvakangofanana kuvandudza kupisa kugadzikana.

Zvigadzirwa Zvakanatsiridzwa uye Hunhu Hwakavandudzwa - Sarudzo chaiyo yeInfrared Absorbers, inobvumira mapurasitiki processor kuti ape zvigadzirwa zvine akagadziridzwa maitiro ekuita uye ane hunogara hwakakwira hwemhando.

Sezvo infrared absorbers ichidhura zvakanyanya kupfuura mamwe maplastic additives ($/gram pachinzvimbo che $/lb), zvakakosha kuti mugadziri atore nekuchenjerera kuumba nemazvo kudzivirira tsvina, uye kuwana mashandiro anodiwa.Izvo zvakakoshawo kuti processor inyatso gadzira mamiriro anodiwa ekugadzirisa kudzivirira kugadzira off-spec zvigadzirwa.Rinogona kunge riri basa rakaoma, asi rinogona kuguma nekukosha kwakawedzerwa zvigadzirwa zvemhando yepamusoro.
