Infrared (IR) radiation imhando yemagetsi emagetsi isingaonekwe neziso remunhu asi inogona kunzwika sekupisa.Iine huwandu hwakasiyana hwekushandisa senge remote control, thermal imaging equipment, uye kunyange kubika.Nekudaro, pane dzimwe nguva pazvinenge zvichidikanwa kuvharira kana kuderedza mhedzisiro yeradio infrared, senge mune kumwe kuyedza kwesainzi, maindasitiri maitiro, kana kunyangwe nekuda kwehutano hwemunhu nekuchengetedza zvikonzero.Muchiitiko ichi, zvinhu zvakananga zvinogona kushandiswa kuderedza kana kuvhara zvachose infrared radiation.

Chimwe chinhu chinowanzo shandiswa kuvhara IR mwaranzi ndeyeIR inovharira zvimedu.Izvi zvimedu zvinowanzo umbwa nemusanganiswa wezvinhu zvakaita sesimbi okisidhi uye zvakagadzirirwa chaizvo kutora kana kuratidza infrared radiation.Masimbi akawanda anowanikwa mune infrared blocking particles anosanganisira zinc oxide, titanium oxide, uye iron oxide.Izvi zvimedu zvinowanzosanganiswa nepolymer kana resin base kugadzira mafirimu kana machira anogona kuiswa kune akasiyana siyana.

Kushanda kwe infrared blocking particles kunoenderana nezvakati wandei, zvinosanganisira saizi uye chimiro chezvimedu, uye kutarisisa kwavo mufirimu kana kupfeka.Kazhinji kutaura, zvidiki zvidiki uye kukwirisa kwakanyanya kunokonzeresa zvirinani IR kuvharira zvivakwa.Mukuwedzera, kusarudzwa kwesimbi oxide kunogonawo kukanganisa kushanda kweiyo infrared blocking material.Semuyenzaniso, zinc oxide zvimedu zvinozivikanwa kuti zvinonyatso kuvharira mamwe mawavelength e-infrared radiation, nepo titanium oxide ichinyanya kushanda kune mamwe wavelengths.

Kuwedzera kune infrared blocking particles, kune zvimwe zvinhu zvinogona kushandiswa kuvharira kana kuderedza infrared radiation.Imwe yakakurumbira sarudzo ndeye kushandisa zvinhu zvine high reflectivity, zvakadai sesimbi sealuminium kana sirivheri.Aya masimbi ane yakakwira yepamusoro reflection, zvinoreva kuti anogona kuratidza huwandu hukuru hwemwaranzi ye infrared kudzokera kwairi.Izvi zvinonyatso kudzikisa huwandu hwema infrared radiation inopfuura nepakati pezvinhu.

Imwe nzira yekuvharisa infrared radiation ndeye kushandisa zvinhu zvine zvinhu zvinotora zvakanyanya.Mamwe ma organic compounds, akadai se polyethylene uye mamwe marudzi egirazi, ane yakakwirira absorption coefficients ye infrared radiation.Izvi zvinoreva kuti vanotora yakawanda infrared radiation inosangana navo, ichidzivirira kuti ipfuure.

Pamusoro peiyo chaiyo zvinhu, ukobvu uye density yezvinhu zvinokanganisawo kugona kwayo kuvhara infrared radiation.Zvishongo zvakakora uye denser kazhinji zvine zvirinani infrared kuvharira hunyanzvi nekuda kwekuwedzera kwenhamba yekunyudza infrared kana kuratidza zvimedu zviripo.

Muchidimbu, kune zvakasiyana-siyana zvezvinhu zvinogona kushandiswa kuvharira kana kuderedza infrared radiation.Infrared blocking particles, zvakadai seaya akagadzirwa nesimbi oxides, anoshandiswa zvakanyanya nekuda kwezvimiro zvawo izvo zvinovabvumira kutora kana kuratidza infrared radiation.Nekudaro, zvimwe zvinhu zvinogona zvakare kushandiswa, senge simbi dzine yakakwira reflectivity kana organic komisheni ine yakakwira absorption coefficients.Zvinhu zvakaita senge saizi, kusungirirwa uye rudzi rwesimbi oxide inoshandiswa inoita basa rakakosha mukubudirira kweIR inovharira zvinhu.Ukobvu uye density zvinopawo mukukwanisa kwechinhu kuvhara infrared radiation.Nekusarudza zvinhu zvakanaka uye kufunga nezvezvinhu izvi, inoshanda IR blocking inogona kuwanikwa mumhando dzakasiyana dzekushandisa.
