Imitha ye-infrared (IR) luhlobo lwemitha yemitha ye-electromagnetic engabonakaliyo kwiliso lomntu kodwa inokuviwa njengobushushu.Inoluhlu olubanzi lwezicelo ezinje ngolawulo olukude, izixhobo zokujonga i-thermal, kunye nokupheka.Nangona kunjalo, kukho amaxesha apho kuyimfuneko ukuvala okanye ukunciphisa imiphumo yemitha ye-infrared, njengakuvavanyo oluthile lwezenzululwazi, iinkqubo zemizi-mveliso, okanye ngenxa yezempilo kunye nezizathu zokhuseleko.Kule meko, izinto ezithile zingasetyenziselwa ukunciphisa okanye ukuvala ngokupheleleyo imisebe ye-infrared.

Enye imathiriyeli eqhele ukusetyenziswa ukuvala imitha ye-IR yiAmasuntswana okuthintela i-IR.La masuntswana ahlala equlunqwe yindibaniselwano yezinto ezifana neeoksidi zetsimbi kwaye zenzelwe ngokukodwa ukufunxa okanye ukubonakalisa imitha ye-infrared.Ezona oxide zentsimbi zixhaphakileyo ezifumaneka kumasuntswana okuthintela i-infrared ziquka i-zinc oxide, i-titanium oxide, kunye ne-iron oxide.Ezi ngqungquthela zihlala zixutywe kunye ne-polymer okanye isiseko se-resin ukwenza iifilimu okanye iingubo ezinokuthi zifakwe kwiindawo ezahlukeneyo.

Ukusebenza kwe-infrared blocking particles kuxhomekeke kwizinto ezininzi, kubandakanywa ubungakanani kunye nokuma kweengqungquthela, kunye nokugxininiswa kwabo kwifilimu okanye kwi-coating.Ngokuqhelekileyo, amasuntswana amancinci kunye nokugxila okuphezulu kubangela iipropati ezingcono zokuthintela i-IR.Ukongezelela, ukhetho lwe-oxide yensimbi lunokuchaphazela nokusebenza kwe-infrared blocking material.Ngokomzekelo, amasuntswana e-zinc oxide ayaziwa ukuba athintele ngokufanelekileyo amaza amaza emitha ye-infrared, ngelixa i-titanium oxide isebenza ngakumbi kwamanye amaza.

Ukongeza kwi-infrared blocking particles, kukho ezinye izinto ezinokusetyenziselwa ukuvimba okanye ukunciphisa imisebe ye-infrared.Olunye ukhetho oludumileyo kukusebenzisa izixhobo ezinokubonakala okuphezulu, njengesinyithi njenge-aluminium okanye isilivere.Ezi zinyithi zinembonakalo ephezulu yomphezulu, nto leyo ethetha ukuba zinokubonisa izixa ezikhulu zemitha ye-infrared ibuyele kumthombo wayo.Oku kunciphisa ngokufanelekileyo ubungakanani bemitha ye-infrared edlula kwizinto eziphathekayo.

Enye indlela yokuthintela imitha ye-infrared kukusebenzisa izinto ezineempawu ezifunxa kakhulu.Ezinye iikhompawundi eziphilayo, ezifana ne-polyethylene kunye neentlobo ezithile zeglasi, zinee-coefficients zokufunxa eziphezulu kwimitha ye-infrared.Oku kuthetha ukuba bafunxa uninzi lwemitha ye-infrared edibana nabo, iyithintele ukuba idlule.

Ukongeza kwizinto ezithile, ubukhulu bezinto kunye nokuxinana kuchaphazela amandla ayo okuthintela imisebe ye-infrared.Iimathiriyeli ezityebileyo nezixineneyo ngokubanzi zinamandla okuthintela i-infrared ngenxa yokunyuka kwenani le-infrared efunxayo okanye ebonisa amasuntswana akhoyo.

Isishwankathelo, kukho izinto ezahlukeneyo ezinokusetyenziselwa ukuvimba okanye ukunciphisa imisebe ye-infrared.Amasuntswana okuthintela i-infrared, ezifana nezo zenziwe nge-metal oxides, zisetyenziswa ngokubanzi ngenxa yeempawu zazo ezithile ezivumela ukuba zifake okanye zibonise imitha ye-infrared.Nangona kunjalo, ezinye izinto zisenokusetyenziswa, njengesinyithi esinokubonakala okuphezulu okanye iikhompawundi ze-organic kunye ne-coefficients ephezulu yokufunxa.Izinto ezifana nobukhulu be-particle, i-concentration kunye nohlobo lwe-oxide yensimbi esetyenzisiweyo idlala indima ebalulekileyo ekusebenzeni kwezixhobo zokuvimbela i-IR.Ukutyeba kunye nokuxinana kukwanegalelo kwisakhono semathiriyeli ukuvala imitha ye-infrared.Ngokukhetha izinto ezifanelekileyo kunye nokuqwalasela le miba, ukuvinjelwa kwe-IR okusebenzayo kunokufezekiswa kuluhlu olubanzi lwezicelo.
