Thaum cov neeg siv khoom yuav cov khaub ncaws sov sov, lawv feem ntau ntsib cov lus hais xws li: "Far infrared self-heating", "Far infrared warms skin", "Far infrared warms", thiab lwm yam. "Far infrared" txhais li cas? kev ua tau zoo? Yuav ua li casntesseb puas muaj ntaubfar-infrared zog?
Dab tsi yog far infrared?
Infrared rays yog ib hom lub teeb nthwv dej uas nws lub wavelength luv dua li xov tooj cua thiab ntev dua li pom lub teeb. Infrared rays tsis pom ntawm qhov muag liab qab. Lub wavelength ntau ntawm infrared rays yog dav heev. Tib neeg faib cov kab hluav taws xob infrared nyob rau hauv qhov sib txawv wavelength nyob rau hauv ze-infrared, nruab nrab-infrared thiab far-infrared cheeb tsam. Far-infrared rays muaj zog nkag mus thiab tawg lub zog, thiab muaj kev tswj qhov kub thiab txias thiab cuam tshuam. Lawv tau yooj yim absorbed los ntawm cov khoom thiab hloov mus rau hauv lub zog sab hauv ntawm cov khoom.
Yuav ua li cas los txheeb xyuas seb cov textiles muaj cov khoom nyob deb-infrared?
GB/T 30127-2013"Kev Tshawb Fawb thiab Kev Ntsuas ntawm Far-Infrared Performance of Textiles" siv ob yam khoom ntawm "far-infrared emissivity" thiab "far-infrared radiation kub nce" los ntsuas seb cov ntaub puas muaj cov khoom nyob deb-infrared.
Qhov deb-infrared emissivity yog tso tus qauv blackbody phaj thiab cov qauv ntawm lub phaj kub ib tom qab, thiab kho qhov kub ntawm lub phaj kub hauv ib ntu kom ncav cuag qhov ntsuas kub; tus qauv blackbody yog ntsuas cais siv qhov ntsuas hluav taws xob nyob deb-infrared nrog cov lus teb spectral uas suav nrog 5 μm ~ 14 μm band. Cov hluav taws xob siv hluav taws xob tom qab lub phaj thiab cov qauv raug them rau ntawm lub phaj kub nce mus txog qhov ruaj khov, thiab qhov deb-infrared emissivity ntawm cov qauv yog xam los ntawm kev xam qhov piv ntawm cov hluav taws xob siv ntawm cov qauv thiab cov qauv blackbody phaj.
Kev ntsuas qhov ntsuas kub nce siab yog ntsuas qhov ntsuas kub ntawm qhov ntsuas qhov ntsuas ntawm qhov ntsuas tom qab qhov hluav taws xob nyob deb-infrared irradiates tus qauv nrog qhov tsis tu ncua irradiation siv rau qee lub sijhawm.
Dab tsi ntawm textiles tuaj yeem ntsuas raws li muaj cov khoom nyob deb-infrared?
Rau cov qauv dav dav, yog tias qhov deb-infrared emissivity ntawm tus qauv tsis tsawg dua 0.88, thiab qhov deb-infrared hluav taws xob kub nce tsis tsawg dua 1.4 ° C, cov qauv muaj cov khoom nyob deb-infrared.
Rau cov qauv xoob xws li flakes, nonwovens, thiab pawg, qhov deb-infrared emissivity tsis tsawg dua 0.83, thiab qhov kub-infrared kub nce tsis tsawg dua 1.7 ° C. Cov qauv muaj cov khoom nyob deb-infrared.
Nws yog ib qho tsim nyog sau cia tias ntau qhov kev ntxhua khaub ncaws kuj muaj qee yam cuam tshuam rau kev ua haujlwm deb-infrared. Yog cov saum toj noindex xav tautseem tau ntsib tom qab ntau qhov kev ntxuav, cov qauv yog suav tias yog cov khoom lag luam nrogntxuav-resistantfar-infrared kev ua tau zoo.
