Yas refractory yog ib qho tseem ceeb ntawm cov khoom siv engineering nrog kev kub siab ua haujlwm, tiv thaiv corrosion, hnav tsis kam thiab lwm yam khoom. Plastics yog tov nrog ntau yam nplaum, muab tub lim, plasticizers, anti-aging agents, thiab lwm yam, thiab tuaj yeem ua tiav thiab tsim khoom raws li kev xav tau sib txawv. Hauv kev lag luam niaj hnub no, cov ntaub ntawv refractory thiab plastics tau siv dav hauv cov haujlwm kub kub refractory xws li refractory partitions, refractory bricks, thiab qhov hauv ob sab phlu.
Ua ntej ntawm tag nrho cov, cov ntaub ntawv refractory thiab plastics muaj qhov kub thiab txias tsis kam, uas tso cai rau lawv tiv taus cua sov thiab thermal shock nyob rau hauv qhov kub thiab txias. Yog li ntawd, lawv tau siv dav hauv qee qhov kev ua haujlwm kub. Piv txwv li, nyob rau hauv boilers ntawm thermal fais fab nroj tsuag, yas yog siv los ua high-temperature partitions los xyuas kom meej lub cev ua hauj lwm ntawm boiler.
Ntxiv nrog rau qhov kub thiab txias tsis kam, plastics kuj muaj kev tiv thaiv corrosion zoo heev, uas ua rau lawv siv dav hauv kev lag luam chemical thiab hlau smelting kev lag luam. Hauv cov chaw tsim khoom uas muaj cov kua qaub thiab alkalis, cov yas tuaj yeem siv los ua cov khoom siv los tiv thaiv kev puas tsuaj rau cov khoom siv los ntawm corrosion los ntawm cov tshuaj tiv thaiv. Hauv kev lag luam steel smelting, plastics yog siv los ua refractory bricks thiab refractory daim hlau los xyuas kom meej kev ruaj ntseg ntawm cov txheej txheem smelting.
Tsis tas li ntawd, cov yas refractory kuj tseem muaj kev hnav zoo heev, uas ua rau lawv siv dav hauv kev txiav nyom, thee mining, mining thiab lwm yam lag luam. Cov yas tuaj yeem siv los ua cov ntaub ntawv hauv ob sab phlu kom ntseeg tau tias kev tsim khoom txuas ntxiv hauv mines thiab quarries. Txhawm rau txhim kho qhov hnav tsis kam ntawm cov cuab yeej siv, cov yas refractory kuj tseem tuaj yeem sib xyaw nrog cov ntaub ntawv hnav-tiv taus zoo los txhim kho lawv cov hnav tsis kam thiab ntxiv dag zog rau tag nrho cov khoom siv refractory.
Feem ntau, cov yas refractory yog cov khoom siv engineering zoo heev. Nws muaj ntau yam ntawm daim ntawv thov teb thiab tsim nyog tsis yog rau kev lag luam uas xav tau kub thiab corrosion kuj, tab sis kuj rau lub sijhawm uas yuav tsum tau muaj lub cev xws li hnav tsis kam.
