Qhov sib txawv ntawm Kub Zaj duab xis PTC rhaub thiab nyias zaj duab xis PTC rhaub
PTC (Positive Temperature Coefficient) cov cua sov yog siv dav hauv ntau qhov chaw, suav nrog cov khoom siv hauv tsev, khoom siv kho mob, cov khoom siv hauv tsev, thiab tsheb. Ntawm ntau hom PTC cua sov, muaj ob pawg tseem ceeb: cov yeeb yaj kiab kub PTC cua sov thiab cov yeeb yaj kiab PTC cov cua sov. Ob hom PTC cua sov muaj qhov zoo thiab qhov tsis zoo, nyob ntawm seb cov ntawv thov tshwj xeeb.
Cov yeeb yaj kiab PTC cov cua sov yog tsim los ntawm kev tso cov khoom siv PTC rau ntawm lub substrate, uas feem ntau yog hlau lossis ceramic phaj. Cov khoom siv PTC muaj qhov ua haujlwm siab ntawm chav tsev kub thiab qis dua ntawm qhov kub siab, hu ua Curie kub. Thaum lub tshuab hluav taws xob siv hluav taws xob, tam sim no ntws los ntawm cov khoom siv PTC, ua kom muaj cua sov vim Joule cua sov. Raws li qhov kub ntawm cov khoom PTC nce, qhov kev tiv thaiv kuj nce ntxiv, ua rau muaj kev txwv tus kheej thiab lub zog tso zis ruaj khov.
Ib qho txiaj ntsig tseem ceeb ntawm cov yeeb yaj kiab kub PTC cov cua sov yog lawv lub zog siab ceev, uas txhais tau hais tias lawv tuaj yeem tsim kom muaj cua sov ntau hauv thaj chaw me me. Cov cuab yeej no ua rau lawv haum rau cov ntawv thov uas xav tau cua sov ceev, xws li defrosting, dehumidification, thiab sterilization. Txawm li cas los xij, qhov poob qis ntawm cov yeeb yaj kiab kub PTC cov cua sov yog lawv cov nqi siab, vim tias cov txheej txheem tso nyiaj thiab cov txheej txheem yog qhov nyuaj thiab xav tau cov cuab yeej kim.
Nyob rau hauv sib piv, nyias zaj duab xis PTC cua sov yog tsim los ntawm depositing PTC cov ntaub ntawv ntawm ib tug substrate, uas feem ntau yog ib tug hloov tau yooj yim polymer zaj duab xis. Cov khoom siv PTC muaj qhov tsis zoo ntawm chav tsev kub thiab muaj kev tiv thaiv ntau dua ntawm Curie kub. Thaum lub tshuab hluav taws xob siv hluav taws xob, tam sim no ntws los ntawm cov khoom siv PTC, ua kom muaj cua sov vim Joule cua sov. Raws li qhov kub ntawm cov khoom siv PTC nce, qhov kev tiv thaiv kuj txo qis, ua rau muaj kev txwv tus kheej thiab lub zog tso zis ruaj khov.
Ib qho txiaj ntsig tseem ceeb ntawm nyias zaj duab xis PTC tso cua sov yog lawv qhov yooj yim, uas txhais tau hais tias lawv tuaj yeem yooj yim ua ke rau hauv cov duab sib txawv thiab ntau thiab tsawg. Cov cuab yeej no ua rau lawv tsim nyog rau cov ntawv thov uas xav tau cov cua sov sib xws, xws li cov khoom siv hnav, cov ntaub ntawv ntse, thiab cov khoom siv tshuaj biomedical. Txawm li cas los xij, ib qho kev poob qis ntawm cov yeeb yaj kiab PTC cov cua sov yog lawv cov hluav taws xob tsis tshua muaj zog, uas txhais tau hais tias lawv yuav siv sij hawm ntev dua los ua kom sov thiab tej zaum yuav tsis haum rau kev siv hluav taws xob siab.
Hauv cov ntsiab lus, cov yeeb yaj kiab kub PTC cua sov thiab cov yeeb yaj kiab nyias PTC cov cua sov muaj cov khoom sib txawv thiab tsim nyog rau kev siv sib txawv. Cov yeeb yaj kiab PTC tso cua sov muaj lub zog siab ceev tab sis tus nqi siab, thaum nyias zaj duab xis PTC cov cua sov muaj lub zog tsawg tab sis muaj kev hloov pauv siab. Raws li qhov yuav tsum tau ua ntawm daim ntawv thov tshwj xeeb, tus tsim qauv yuav tsum xaiv hom tsim nyog ntawm PTC rhaub kom ua tau raws li qhov xav tau kev ua tau zoo thiab cov nqi siv tau.
