Teko ea thepa e hole ea infrared ea masela

Ha bareki ba reka liaparo tse futhumetseng tsa mariha, hangata ba kopana le mapetjo a kang: "Far infrared self-heating", "Far infrared warms skin", "Far infrared keeps warm", joalo-joalo. Hantle-ntle "infrared" e bolela'ng? tshebetso? Mokhoa oa holemohahore na lesela le na lethepa e hole ea infrared?

Ke eng e hole ea infrared?

Mahlaseli a infrared ke mofuta oa leqhubu la khanya leo bolelele ba lona bo leng bokhutšoanyane ho feta maqhubu a seea-le-moea 'me le lelelele ho feta khanya e bonahalang. Mahlaseli a infrared ha a bonahale ka mahlo. Leqhubu la maqhubu a mahlaseli a infrared le pharaletse haholo. Batho ba arola mahlaseli a infrared ka mekhahlelo e fapaneng ea maqhubu ho ea libakeng tse haufi tsa infrared, mid-infrared le far-infrared. Mahlaseli a infrared a na le matla a matla a ho phunyeletsa le a mahlaseli, 'me a na le taolo e kholo ea mocheso le liphello tsa resonance. Li kenngoa habonolo ke lintho ebe li fetoloa matla a ka hare a lintho.

U ka tseba joang hore na masela a na le thepa e hole ea infrared?

GB/T 30127-2013"Detection and Evaluation of Far-Infrared Performance of Textiles" e sebelisa lintho tse peli tsa "hole-infrared emissivity" le "ho phahama ha mocheso oa mahlaseli a mahlaseli a kotsi" ho lekola hore na masela a na le thepa e hole ea infrared.

Emissivity e hole ea infrared ke ho beha poleiti e tloaelehileng ea "blackbody" le sampole holim'a poleiti e chesang ka mor'a e 'ngoe, le ho lokisa mocheso oa holim'a mocheso o chesang ka tatellano ho fihlela mocheso o boletsoeng; "blackbody" e tloaelehileng e lekantsoe ka thoko ho sebelisoa mokhoa oa ho lekanya mahlaseli a hole a infrared ka lebelo la karabelo la spectral le koahelang sehlopha sa 5 μm ~ 14 μm. Matla a mahlaseli ka mor'a hore poleiti le sampole li koaheloe holim'a poleiti e chesang e fihle ho tsitsitse, 'me hole hole ho tsoa ho infrared ea sampole ho baloa ka ho bala karo-karolelano ea matla a mahlaseli a sampuli le poleiti e tloaelehileng ea blackbody.

Tekanyo ea ho nyoloha ha mocheso ke ho lekanya ho phahama ha mocheso holim'a sebaka sa teko sa sampuli ka mor'a hore mohloli oa mahlaseli a hole a mahlaseli a kotsi a khabise sampuli ka matla a sa khaotseng a mahlaseli ka nako e itseng.

Ke masela a mofuta ofe a ka nkoang a na le thepa ea infrared?

Bakeng sa disampole tse akaretsang, haeba tlhahiso e hole ea infrared ea sampole e se ka tlase ho 0.88, 'me mocheso oa mahlaseli a kotsi a hole o se ka tlase ho 1.4 ° C, sampole e na le lisebelisoa tse hole tsa infrared.

Bakeng sa lisampole tse hlephileng tse kang li-flakes, li-nonwovens, le liqubu, mocheso oa infrared ha o ka tlase ho 0.83, 'me mocheso oa mahlaseli a kotsi a hole ha o ka tlase ho 1.7 ° C. Mohlala o na le lisebelisoa tse hole tsa infrared.

Ke habohlokoa ho hlokomela hore ho hlatsoa ka makhetlo a mangata ho boetse ho na le tšusumetso e itseng ho ts'ebetso ea hole ea infrared. Haeba ka holimolitlhoko tsa indexli ntse li kopane ka mor'a ho hlatsoa hangata, mohlala o nkoa e le sehlahisoa se nang lee sa hlatsoengtshebetso e hole ya infrared.
