Cov khoom siv zoo ntawm lub tshuab foob yuav ua rau koj zoo siab thaum lub sijhawm thov.
Cov khoom siv foob siv tau ntau yam khoom siv nyob ntawm seb daim ntawv thov foob siv li cas. Los ntawm kev xaiv cov khoom siv kom raug rau kojtwj tso kua mis, nws yuav kav ntev dua, tiv thaiv kev txij nkawm thiab kev ua tsis tiav tsis tsim nyog.
Cov ntaub ntawv siv rau dab tsilub tshuab foobs?
Muaj ntau yam khoom siv tau rau cov foob nyob ntawm seb lawv xav tau dab tsi thiab ib puag ncig li cas. Los ntawm kev xav txog cov khoom siv xws li qhov nyuaj, qhov nruj, qhov nthuav dav thermal, kev hnav thiab kev tiv taus tshuaj lom neeg, koj tuaj yeem nrhiav tau cov khoom zoo tshaj plaws rau koj lub foob pob hluav taws xob.
Thaum cov foob pob hluav taws xob thawj zaug tuaj txog, cov ntsej muag foob feem ntau yog ua los ntawm cov hlau xws li cov hlau tawv, tooj liab thiab tooj dag. Tau ntau xyoo, cov ntaub ntawv txawv txawv tau siv rau lawv cov txiaj ntsig zoo, suav nrog cov khoom siv av nplaum thiab ntau qib ntawm cov pa roj carbon hluav taws xob.
Daim ntawv teev cov ntaub ntawv feem ntau rau lub ntsej muag foob
Cov pa roj carbon (CAR) / Cov khoom siv av nplaum (CER)
Cov khoom no feem ntau muaj 99.5% txhuas oxide uas muaj kev tiv thaiv zoo vim nws qhov tawv. Vim tias cov pa roj carbon tsis muaj zog, nws tuaj yeem tiv taus ntau yam tshuaj sib txawv, txawm li cas los xij nws tsis haum thaum raug cua sov 'cuam tshuam'. Thaum muaj kev hloov pauv kub heev, nws tuaj yeem tawg lossis tawg.
Silicone Carbide (SiC) thiab sintered silicone carbide
Cov khoom siv no yog tsim los ntawm kev sib xyaw silica thiab coke thiab nws zoo ib yam li Ceramic, txawm li cas los xij nws tau txhim kho cov yam ntxwv ntawm lubrication thiab nyuaj dua. Silicone carbide qhov nyuaj ua rau nws yog ib qho kev daws teeb meem zoo heev rau cov chaw ib puag ncig hnyav thiab nws kuj tuaj yeem rov ua dua thiab txhuam kom rov kho dua lub foob ntau zaus hauv nws lub neej.
Tungsten Carbide (TC)
Ib yam khoom siv tau ntau yam xws lisilicone carbidetab sis nws zoo dua rau cov ntawv thov siab vim muaj qhov elasticity siab piv rau. Qhov no tso cai rau 'flex' me ntsis thiab tiv thaiv kev cuam tshuam ntawm lub ntsej muag. Ib yam li Silicone Carbide nws tuaj yeem rov ua dua thiab txhuam.
