Hauv kev lag luam, cov cuab yeej siv feem ntau ntsib ntau yam teeb meem hnyav ib puag ncig, thiab hnav thiab tsim kua muag yog ib qho ntawm cov teeb meem loj. Hnav thiab tsim kua muag tsis tsuas yog txo cov kev ua tau zoo thiab kev ua haujlwm ntawm cov khoom siv, tab sis kuj tseem tuaj yeem ua rau cov khoom siv tsis ua haujlwm, nce nqi tu thiab kev poob qis. Qhov tshwm sim ntawmsilicon carbide hnav-resistant hauv ob sab phluyog zoo li tus neeg saib xyuas tsis pom, tiv thaiv hnav thiab txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv. Niaj hnub no, peb yuav nthuav tawm nws daim ntaub thaiv tsis meej thiab delve rau hauv nws txoj haujlwm ua haujlwm.
Silicon carbide (SiC) yog qhov sib xyaw ua ke ntawm ob lub ntsiab lus, silicon thiab carbon. Nws cov qauv siv lead ua yog qhov tshwj xeeb heev, nrog rau cov txheej txheem hauv paus yog interwoven SiC thiab CSi tetrahedra. Cov qauv nruj thiab ruaj khov no endows silicon carbide nrog ntau yam khoom zoo, xws li cov cua sov zoo, tiv thaiv corrosion, siab hardness, thiab hnav tsis kam, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev hnav-tiv taus hauv ob sab phlu.
Yog li, yuav ua li cas hnav-resistant hauv ob sab phlu ua los ntawm cov tshuaj tiv thaiv sintered silicon carbide ceramics ua haujlwm?
High hardness los tiv thaiv hnav: Cov tshuaj tiv thaiv sintered silicon carbide ceramics muaj ultra-siab hardness, thib ob tsuas yog pob zeb diamond. Thaum cov khoom siv sab nraud cuam tshuam los yog rub tawm ntawm phab ntsa sab hauv ntawm cov khoom siv, cov khoom siv hauv cov khoom hnav-tiv taus, nrog nws cov hardness siab, tuaj yeem tiv taus qhov kev puas tsuaj ntawm cov sab nraud, zoo li cov ntaub thaiv npog ruaj khov, zoo heev txo cov qib ntawm cov khoom hnav thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv.
Kev ruaj ntseg tshuaj zoo tiv thaiv corrosion: Hauv ntau qhov xwm txheej, cov cuab yeej siv tsis yog tsuas yog ntsib kev hnav thiab tsim kua muag, tab sis kuj tuaj yeem cuam tshuam nrog ntau yam tshuaj, ua rau muaj kev hem thawj ntawm corrosion. Cov tshuaj tiv thaiv sintered silicon carbide ceramics muaj cov tshuaj lom neeg ruaj khov thiab tuaj yeem tiv thaiv kev xeb los ntawm cov tshuaj lom neeg, yog li ua kom muaj kev ua haujlwm zoo ntawm cov hnav-tiv taus hauv ob sab hauv cov tshuaj lom neeg.
Qhov kub thiab txias tsis kam thiab hloov mus rau qhov kub thiab txias: Qee cov txheej txheem tsim khoom lag luam tuaj yeem tsim kom muaj qhov kub thiab txias, thiab cov khoom siv zoo tib yam tuaj yeem ua mos, deformed, los yog puas thaum kub kub. Txawm li cas los xij, cov tshuaj tiv thaiv sintered silicon carbide ceramics tuaj yeem ncav cuag qhov siab tshaj plaws kev ua haujlwm kub ntawm 1350 ℃ thiab tuaj yeem siv tau ntev ntev txawm tias qhov kub siab no. Nws tuaj yeem tiv thaiv cov khoom siv thiab qhov chaw los ntawm kev ua kom thermal deformation thiab softening vim qhov kub thiab txias, kom ntseeg tau tias hnav-resistant liners tseem tuaj yeem muab kev tiv thaiv zoo rau cov khoom siv hauv qhov kub thiab txias.
Piv nrog rau lwm yam ntaub ntawv hnav-tiv taus hauv ob sab phlu, cov tshuaj tiv thaiv sintered silicon carbide ceramic hnav-resistant hauv ob sab phlu muaj qhov zoo. Piv txwv li, nws qhov hardness deb tshaj li ntawm cov ceramics zoo tib yam xws li alumina thiab zirconia, thiab nws yog superior rau hnav tsis kam; Nws cov tshuaj lom neeg ruaj khov thiab kub tsis kam kuj tseem zoo dua li qee cov khoom siv, thiab nws tuaj yeem hloov mus rau ntau qhov chaw ua haujlwm thiab xav tau kev ua haujlwm.
Silicon carbide hnav-resistant hauv ob sab phlu yog dav siv nyob rau hauv ntau yam lag luam xws li fais fab, steel, ceramics, high-temperature kilns, mining, thee, roj av, tshuaj, thiab machinery manufacturing. Hauv cov kev lag luam no, nws tiv thaiv ntau yam khoom siv, ua kom cov khoom lag luam du, thiab txo cov nqi ua haujlwm rau cov lag luam.
Silicon carbide hnav-tiv taus hauv ob sab phlu plays lub luag haujlwm tseem ceeb hauv kev lag luam vim nws txoj haujlwm ua haujlwm tshwj xeeb thiab kev ua haujlwm zoo heev. Raws li cov kws tshaj lij cov chaw tsim khoom ntawm cov tshuaj tiv thaiv sintered silicon carbide ceramics, Shandong Zhongpeng ib txwm tau cog lus los muab cov neeg siv khoom zoo, pab ntau yam kev lag luam txhim kho cov cuab yeej ua haujlwm, thiab ua tiav cov khoom lag luam zoo. Yog tias koj txaus siab rau 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.
