Refractory yog ib yam khoom uas muaj qhov kub thiab txias heev uas feem ntau siv hauv kev lag luam kub xws li cement, iav, steel, petrochemicals, thiab hluav taws xob. Nrog kev txhim kho txuas ntxiv ntawm thev naus laus zis, hom thiab daim ntawv thov ntawm cov ntaub ntawv refractory kuj nthuav dav.
Kev txhim kho keeb kwm ntawm cov ntaub ntawv refractory tuaj yeem taug qab mus rau lub sijhawm qub. Thaum ntxov li 3000 BC hauv tebchaws Iziv thaum ub, tib neeg tau pib siv cov khoom siv kub-resistant xws li cov tais diav rau kev ua cov khoom siv thiab cov tais diav. Nyob rau lub sijhawm tam sim no, tib neeg qhov kev thov rau cov khoom siv refractory tau nce siab dua, yog li kev tsim cov cuab yeej siv cov khoom siv refractory tseem niaj hnub txhim kho thiab txhim kho.
Tam sim no, cov ntaub ntawv refractory feem ntau muab faib ua ob pawg: cov ntaub ntawv inorganic refractory thiab cov ntaub ntawv organic refractory. Ntawm lawv, inorganic refractory cov ntaub ntawv muaj xws li siab alumina, silicate, silicon carbide, silicon nitride, zirconia thiab lwm yam, thaum organic refractory cov ntaub ntawv muaj xws li carbon fiber thiab lwm yam.
Cov ntaub ntawv refractory yog siv rau ntau yam kev siv, xws li kub-smelting, casting, iav ua, hluav taws xob fais fab, hlau thiab lwm yam lag luam. Cov teb no muaj kev ua tau zoo heev rau cov ntaub ntawv refractory, xws li high-temperature compression resistance, high-temperature earthquake resistance, slag erosion resistance, chemical stability, thiab lwm yam. Yog li ntawd, qhov zoo thiab kev ua tau zoo ntawm cov ntaub ntawv refractory ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg. thiab kev nyab xeeb ntawm kev lag luam ntau lawm.
Tib neeg tseem niaj hnub ua kev tshawb fawb thiab kev txhim kho ntawm kev tsim khoom thiab kev siv cov khoom siv refractory. Piv txwv li, kev siv nanotechnology tuaj yeem txhim kho kev ua haujlwm ntawm cov ntaub ntawv refractory, ua rau lawv tiv taus kub thiab yaig. Nyob rau tib lub sijhawm, tib neeg kuj tseem sim siv cov ntaub ntawv refractory hauv kev tiv thaiv ib puag ncig thiab lub zog, xws li siv cov khoom siv refractory los ua cov roj teeb tshiab.
Feem ntau, cov khoom siv refractory yog cov khoom siv tseem ceeb heev uas ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg thiab kev nyab xeeb ntawm kev lag luam niaj hnub no. Nrog kev txhim kho txuas ntxiv ntawm thev naus laus zis, tib neeg qhov kev thov rau cov khoom siv refractory tseem nce ntxiv, yog li kev tshawb fawb thiab kev tsim cov khoom siv refractory yuav dhau los ua qhov tseem ceeb.
