Hauv kev lag luam, cov khoom siv feem ntau ntsib ntau yam teeb meem ib puag ncig hnyav, thiab kev hnav thiab tsim kua muag yog ib qho ntawm cov teeb meem loj. Kev hnav thiab tsim kua muag tsis yog tsuas yog txo qhov kev ua tau zoo thiab kev ua haujlwm ntawm cov khoom siv, tab sis kuj tseem yuav ua rau cov khoom siv tsis ua haujlwm, ua rau cov nqi kho thiab lub sijhawm tsis ua haujlwm ntau ntxiv. Qhov tshwm sim ntawmsilicon carbide hnav-resistant liningzoo li tus neeg saib xyuas uas tsis pom, tiv taus kev hnav thiab ua kom cov khoom siv siv tau ntev. Hnub no, peb yuav qhia nws daim ntaub thaiv tsis meej thiab kawm txog nws txoj kev ua haujlwm.
Silicon carbide (SiC) yog ib qho khoom sib xyaw ua ke los ntawm ob lub ntsiab lus, silicon thiab carbon. Nws cov qauv siv lead ua yog qhov tshwj xeeb heev, nrog rau cov qauv tseem ceeb yog SiC thiab CSi tetrahedra sib xyaw ua ke. Cov qauv nruj thiab ruaj khov no ua rau silicon carbide muaj ntau yam zoo heev, xws li kev tiv taus kub zoo, kev tiv taus corrosion, kev tawv siab, thiab kev tiv taus hnav, ua rau nws yog cov khoom siv zoo tshaj plaws rau kev ua cov ntaub hauv qab uas tiv taus hnav.
Yog li, lub hauv paus tiv taus hnav ua los ntawm cov tshuaj tiv thaiv sintered silicon carbide ceramics ua haujlwm li cas?
Muaj zog heev los tiv taus kev hnav: Cov khoom siv silicon carbide ceramics uas tau sintered muaj qhov nyuaj heev, thib ob tsuas yog pob zeb diamond xwb. Thaum cov khoom sab nraud cuam tshuam lossis txhuam rau ntawm phab ntsa sab hauv ntawm cov khoom siv, cov ntaub thaiv uas tiv taus kev hnav, nrog nws qhov nyuaj siab, tuaj yeem tiv taus kev puas tsuaj ntawm cov zog sab nraud no, zoo li lub ntaub thaiv ruaj khov, txo qhov kev hnav ntawm cov khoom siv thiab ua kom lub neej ua haujlwm ntev dua.
Kev ruaj khov tshuaj zoo tiv thaiv xeb: Hauv ntau qhov xwm txheej kev lag luam, cov khoom siv tsis yog tsuas yog ntsib kev hnav thiab tsim kua muag xwb, tab sis kuj tseem kov tau ntau yam tshuaj lom neeg, ua rau muaj kev hem thawj ntawm kev xeb. Cov khoom siv sintered silicon carbide ceramics muaj kev ruaj khov tshuaj zoo thiab tuaj yeem tiv thaiv kev xeb los ntawm cov tshuaj lom neeg, yog li ua kom ntseeg tau tias kev ua haujlwm ib txwm ntawm cov ntaub thaiv kev hnav-resistant hauv cov chaw muaj tshuaj lom neeg nyuaj.
Kev tiv taus kub thiab kev hloov pauv mus rau qhov chaw kub siab: Qee cov txheej txheem tsim khoom lag luam yuav tsim kom muaj qhov kub siab, thiab cov khoom siv ib txwm yuav mos, deformed, lossis txawm tias puas tsuaj ntawm qhov kub siab. Txawm li cas los xij, cov tshuaj tiv thaiv sintered silicon carbide ceramics tuaj yeem ncav cuag qhov kub siab tshaj plaws ntawm 1350 ℃ thiab tuaj yeem siv tau ruaj khov rau lub sijhawm ntev txawm tias nyob rau qhov kub siab no. Nws tuaj yeem tiv thaiv cov khoom thiab cov khoom los ntawm kev hloov pauv thermal thiab softening vim qhov kub siab, kom ntseeg tau tias cov ntaub thaiv kev hnav-resistant tseem tuaj yeem muab kev tiv thaiv txhim khu kev qha rau cov khoom siv hauv qhov chaw kub siab.
Piv nrog rau lwm hom ntaub thaiv uas tiv taus kev hnav, cov ntaub thaiv uas tiv taus kev hnav uas ua los ntawm cov tshuaj reaction sintered silicon carbide ceramic muaj qhov zoo pom tseeb. Piv txwv li, nws qhov nyuaj dua li cov ceramics ib txwm xws li alumina thiab zirconia, thiab nws zoo dua hauv kev tiv taus kev hnav; Nws cov tshuaj lom neeg ruaj khov thiab kev tiv taus kub siab kuj zoo dua li qee cov ntaub ntawv ib txwm muaj, thiab nws tuaj yeem hloov kho rau qhov chaw ua haujlwm nyuaj thiab xav tau ntau dua.
Cov ntaub thaiv uas tiv taus kev hnav ntawm silicon carbide yog siv dav hauv ntau yam lag luam xws li fais fab, hlau, ceramics, qhov cub kub siab, kev tsuas, thee, roj av, tshuaj lom neeg, thiab kev tsim tshuab. Hauv cov lag luam no, nws tiv thaiv ntau yam khoom siv, ua kom muaj kev tsim khoom zoo, thiab txo cov nqi ua haujlwm rau cov tuam txhab.
Cov ntaub thaiv kev hnav-resistant silicon carbide ua lub luag haujlwm tseem ceeb hauv kev lag luam vim nws txoj cai ua haujlwm tshwj xeeb thiab kev ua tau zoo heev. Ua tus kws tshaj lij tsim cov khoom siv ceramics sintered silicon carbide, Shandong Zhongpeng yeej ib txwm cog lus los muab cov khoom zoo rau cov neeg siv khoom, pab ntau yam kev lag luam txhim kho kev ua haujlwm ntawm cov khoom siv, thiab ua tiav kev tsim khoom zoo. Yog tias koj xav tau peb cov khoom, thov koj xav tiv tauj peb txhua lub sijhawm thiab cia peb pab txhawb kev txhim kho kev lag luam ua ke.
