Nrog rau kev txhim kho tas mus li ntawm kev lag luam thiab thev naus laus zis, ntau yam khoom siv hauv qhov chaw kub siab tab tom ntsib teeb meem loj heev. Hauv cov xwm txheej zoo li no, cov txheej txheem tiv taus kub siab tau dhau los ua cov thev naus laus zis tseem ceeb uas tuaj yeem muab kev tiv thaiv cua sov zoo rau ntau yam khoom siv thiab xyuas kom meej tias lawv ruaj khov thiab siv tau ntev hauv qhov chaw kub siab.
Cov txheej txheem tiv taus kub siab yog ib txheej txheej tsim tshwj xeeb uas muaj kev tiv taus kub zoo heev. Nws tuaj yeem tiv taus qhov kub siab heev los ntawm ob peb puas degrees Celsius mus rau ntau txhiab degrees Celsius thiab tswj nws cov khoom siv lub cev thiab tsos kom ruaj khov ntev. Qhov no ua rau cov txheej txheem tiv taus kub siab yog thawj qhov kev xaiv hauv ntau yam lag luam, tshwj xeeb tshaj yog hauv aerospace, petrochemicals, automotive manufacturing thiab power generation.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov txheej txheem tiv taus kub siab yog lawv cov thermal conductivity zoo heev. Nws tuaj yeem nqus thiab coj cua sov los ntawm qhov chaw ntawm cov khoom uas tau coated, ua kom qhov kub ntawm cov khoom uas tau coated qis dua qhov kub ib puag ncig, yog li txo qhov kev pheej hmoo ntawm kev xeb thiab kev laus.
Tsis tas li ntawd xwb, cov txheej txheej uas tiv taus kub siab kuj muaj cov khoom tiv thaiv kab mob zoo heev, uas tuaj yeem tiv thaiv kev oxidation ntawm cov khoom txheej thaum kub siab thiab tsim cov kab nrib pleb thermal. Cov txheej txheej uas tiv taus kub siab muaj ntau yam kev siv. Nws tuaj yeem siv los tiv thaiv ntau yam hlau thiab cov khoom tsis yog hlau, xws li hlau, txhuas alloys, ceramics, thiab lwm yam, ua lub "daim thaiv thermal". Lawv tuaj yeem raug txheej rau ntawm cov kav dej, boilers, cub tawg, cav, cov khoom hloov pauv cua sov thiab lwm yam khoom siv kom txo tau qhov poob cua sov, txhim kho kev siv hluav taws xob, thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv.
Tsis tas li ntawd xwb, cov txheej txheej uas tiv taus kub siab kuj muaj kev hloov pauv zoo rau ib puag ncig. Feem ntau lawv siv cov thev naus laus zis tiv thaiv hluav taws kub tsis siv neeg, uas tuaj yeem txo qhov kev sib kis ntawm hluav taws thiab qhov tshwm sim ntawm kev nyab xeeb los ntawm kev tiv thaiv hluav taws zoo thiab kev cais tawm cua sov. Tib lub sijhawm, lawv feem ntau ua tau raws li cov kev cai tiv thaiv ib puag ncig, ua rau lawv siv dav hauv qhov chaw nyob hauv tsev zoo thiab muaj kev nyab xeeb.
Hauv luv luv, kub siabCov txheej txheej tiv taus hluav taws xob, ua cov khoom siv tiv thaiv tseem ceeb, ua lub luag haujlwm tseem ceeb hauv qhov chaw kub siab. Lawv muab kev tiv thaiv thermal zoo tiv thaiv cov khoom siv laus, oxidation thiab thermal tawg. Los ntawm kev txo qhov poob zog thiab txhim kho kev ua haujlwm ntawm cov khoom siv, cov txheej txheej tiv taus kub siab coj cov txiaj ntsig zoo rau kev lag luam thiab ib puag ncig rau ntau yam kev lag luam. Txawm hais tias nyob rau hauv aerospace, zog lossis lwm yam kev lag luam, cov txheej txheej tiv taus kub siab yog tus khub txhim khu kev qha hauv kev tiv thaiv cov ntaub ntawv.
