Cov ntaub ntawv refractory xa mus rau cov ntaub ntawv zoo heev corrosion kuj thiab kub tsis kam nyob rau hauv corrosive ib puag ncig xws li kub, siab siab, muaj zog acid thiab alkali. Nws yog dav siv hauv metallurgy, tsev cov ntaub ntawv, tshuaj lom neeg kev lag luam thiab lwm yam lag luam. Thaum lub sij hawm mining, smelting thiab ua, cov ntaub ntawv refractory yog yuav tsum tau nyob rau hauv industrial cheeb tsam uas phau ntawv ua hauj lwm, machinery thiab khoom siv, vim hais tias kub kub thiab corrosion feem ntau tshwm sim nyob rau hauv cov xwm txheej no.
Muaj ntau hom khoom siv refractory, uas tuaj yeem faib ua peb hom: inorganic non-metallic refractory cov ntaub ntawv, hlau refractory cov ntaub ntawv thiab cov ntaub ntawv refractory composite, ntawm cov khoom inorganic non-metallic refractory yog feem ntau. Cov khoom tseem ceeb ntawm cov khoom siv refractory no muaj xws li oxides, nitrides, carbides, thiab lwm yam. Cov hom tshwj xeeb muaj xws li silicon carbide, aluminium oxide, silicon nitride, thiab lwm yam. Qhov zoo ntawm cov khoom siv refractory yog: lub teeb yuag, siab zog, corrosion resistance, durability. , thiab lwm yam, thiab yog dav siv nyob rau hauv industrial teb.
Cov khoom siv refractory muaj ntau yam kev siv. Ua ntej tshaj plaws, nws muaj cov ntawv thov ntau tshaj plaws hauv kev lag luam steel. Nyob rau hauv qhov kub-kub smelting ib puag ncig ntawm kev lag luam steel, ntau lub cub tawg, cov kav dej thiab lwm yam khoom siv yuav tsum tau ua, thiab cov cuab yeej no txhua tus yuav tsum tau siv cov khoom siv refractory. Tsis tas li ntawd, kev tsim kho kev lag luam muaj kev xav tau zoo rau cov khoom siv refractory, tshwj xeeb tshaj yog nyob rau hauv cov tsev siab siab, tunnels thiab mines, qhov twg cov ntaub ntawv refractory nrog lub zog siab, hluav taws kub, tiv thaiv corrosion thiab lwm yam khoom yuav tsum tau ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. chaw ua haujlwm.
Tsis tas li ntawd, kev lag luam tshuaj lom neeg, hluav taws xob hluav taws xob, aerospace, kev thauj mus los thiab lwm yam kev lag luam yuav tsum muaj ntau cov ntaub ntawv refractory. Cov ntaub ntawv refractory no muaj kev siv sib txawv hauv ntau qhov kev lag luam. Nrog rau txoj kev loj hlob sai ntawm kev lag luam niaj hnub no, qhov kev thov rau cov khoom siv refractory nyob rau hauv ntau yam xwm txheej ntawm kev lag luam yuav nce.
Kev xaiv cov khoom ntawm cov khoom siv refractory feem ntau yog nyob ntawm qhov kev siv scenario. Piv txwv li, rau cov ntaub ntawv refractory ntawm qhov kub thiab txias, silicon carbide yog qhov tsim nyog dua vim tias nws muaj kev tiv thaiv zoo rau corrosive ib puag ncig xws li kub kub, kub siab, muaj zog acids thiab alkalis, thaum alumina tsim nyog rau kev tsim cov khoom hauv tsev xws li refractory cib. thiab refractory steel. , vim tias nws qhov kub thiab txias tsis siab, tab sis nws muaj lub zog txhua yam thiab zoo kub tsis kam.
Tsis tas li ntawd, cov duab thiab thickness ntawm cov ntaub ntawv refractory yuav tsum tau xaiv raws li qhov xav tau tiag tiag. Piv txwv li, ib puag ncig tus phooj ywg grey pob zeb uas muaj cov khoom siv rooj zaum yuav raug tsim nrog cov khoom siv sib sib zog nqus, hluav taws-resistant, thiab ib puag ncig tus phooj ywg. Rau lwm qhov piv txwv, qhov kev txwv hluav taws yuav tsum tau ua rau cov tsev siab siab siab heev, yog li peb xaiv los tsim lawv nrog cov khoom siv hluav taws xob ntau dua thiab corrosion-resistant kom muaj kev nyab xeeb ntawm lub tsev.
Nyob rau hauv luv luv, cov ntaub ntawv refractory yog dav siv nyob rau hauv ntau yam industries, thiab nws tseem yog ib qho tseem ceeb heev rau xaiv cov khoom refractory haum. Kuv vam tias los ntawm tsab xov xwm no, kuv tuaj yeem pab koj nkag siab zoo dua cov kev paub ntawm cov ntaub ntawv refractory, thiaj li muab koj cov khoom siv refractory zoo dua.
