Ma radiation a infrared (IR) ndi mtundu wa radiation yamagetsi yomwe imakhala yosawoneka ndi maso a munthu koma imatha kumveka ngati kutentha.Ili ndi ntchito zosiyanasiyana monga zowongolera zakutali, zida zojambulira zamafuta, komanso kuphika.Komabe, pali nthawi zina zomwe zimafunika kuletsa kapena kuchepetsa zotsatira za radiation ya infrared, monga kuyesa kwina kwa sayansi, njira zamafakitale, ngakhale pazifukwa zaumoyo ndi chitetezo.Pankhaniyi, zida zapadera zitha kugwiritsidwa ntchito kuti zichepetse kapena kutsekereza ma radiation a infrared.

Chinthu chimodzi chomwe chimagwiritsidwa ntchito kwambiri kuletsa ma radiation a IR ndiIR blocking particles.Tinthu ting'onoting'ono timeneti timapangidwa ndi zinthu monga zitsulo zotchedwa oxides ndipo zimapangidwira kuti zizitha kuyamwa kapena kuwonetsa kuwala kwa infuraredi.Ma oxides odziwika kwambiri omwe amapezeka mu tinthu tating'onoting'ono ta infrared ndi zinc oxide, titanium oxide, ndi iron oxide.Tinthu tating'onoting'ono timeneti timasakanizidwa ndi polima kapena utomoni woyambira kupanga mafilimu kapena zokutira zomwe zingagwiritsidwe ntchito pamitundu yosiyanasiyana.

Mphamvu ya infuraredi kutsekereza particles zimadalira zinthu zingapo, kuphatikizapo kukula ndi mawonekedwe a particles, ndi ndende yawo mu filimu kapena ❖ kuyanika.Nthawi zambiri, tinthu tating'onoting'ono komanso kuchuluka kwambiri kumapangitsa kuti IR ikhale yabwinoko.Komanso, kusankha zitsulo okusayidi kungakhudzenso mphamvu ya infuraredi kutsekereza zakuthupi.Mwachitsanzo, tinthu tating'onoting'ono ta zinc oxide timadziwika kuti timatsekereza ma radiation ena a infrared, pomwe titaniyamu oxide imakhala yogwira mtima pamafunde ena.

Kuphatikiza pa ma infrared blocking particles, palinso zida zina zomwe zingagwiritsidwe ntchito kutsekereza kapena kuchepetsa ma radiation a infrared.Njira imodzi yotchuka ndiyo kugwiritsa ntchito zinthu zowoneka bwino kwambiri, monga zitsulo monga aluminiyamu kapena siliva.Zitsulo izi zimakhala ndi mawonekedwe apamwamba kwambiri, zomwe zikutanthauza kuti zimatha kuwonetsa ma radiation ambiri a infrared kubwerera komwe adachokera.Izi zimachepetsa bwino kuchuluka kwa ma radiation a infrared omwe amadutsa pazinthuzo.

Njira ina yoletsera ma radiation a infrared ndi kugwiritsa ntchito zida zomwe zimayamwa kwambiri.Zinthu zina zakuthupi, monga polyethylene ndi mitundu ina yagalasi, zimakhala ndi mayamwidwe apamwamba a radiation ya infrared.Izi zikutanthauza kuti amayamwa ma radiation ambiri a infrared omwe amakumana nawo, kuwaletsa kuti asadutse.

Kuphatikiza pa zinthu zenizeni, makulidwe ndi kachulukidwe kazinthuzo zimakhudzanso kuthekera kwake kuletsa ma radiation a infrared.Zipangizo zokhuthala komanso zowonda nthawi zambiri zimakhala ndi kuthekera kotsekereza kwa infrared chifukwa cha kuchuluka kwa zinthu zomwe zimayamwa kapena zowunikira.

Mwachidule, pali zida zosiyanasiyana zomwe zingagwiritsidwe ntchito kutsekereza kapena kuchepetsa ma radiation a infrared.Ma infrared blocking particles, monga opangidwa ndi metal oxides, amagwiritsidwa ntchito kwambiri chifukwa cha zinthu zake zenizeni zomwe zimawalola kuyamwa kapena kuwonetsa kuwala kwa infrared.Komabe, zida zina zitha kugwiritsidwanso ntchito, monga zitsulo zowoneka bwino kwambiri kapena ma organic compounds okhala ndi mayamwidwe apamwamba kwambiri.Zinthu monga kukula kwa tinthu, ndende ndi mtundu wa oxide zitsulo zomwe zimagwiritsidwa ntchito zimagwira ntchito yofunika kwambiri pakuchita bwino kwa zida zotsekereza za IR.Makulidwe ndi kachulukidwe zimathandizanso kuti chinthu chitha kutsekereza ma radiation a infrared.Posankha zida zoyenera ndikuganizira izi, kutsekereza kwa IR kogwira mtima kumatha kupezeka m'mapulogalamu osiyanasiyana.
