Tungsten Carbide yog qhov zoo tshaj plaws rau kev siv siab. Nws cov modulus siab ntawm elasticity pab tiv thaiv kev cuam tshuam ntawm lub ntsej muag, ua kom ntseeg tau tias muaj kev ua tau zoo. Tsis tas li ntawd, nws tuaj yeem rov ua dua thiab txhuam kom rov siv dua, uas ua rau nws pheej yig dua.
Silicon Carbide thiab Tungsten Carbide txhua tus muaj cov txiaj ntsig tshwj xeeb ua cov ntaub ntawv foob. Silicon Carbide ua tau zoo heev hauv qhov kub thiab txias thiab cov chaw muaj tshuaj lom neeg, thaum Tungsten Carbide muab kev tawv thiab kev tiv thaiv kev hnav zoo heev.
Rau cov ntawv thov uas xav tau kev ruaj khov thiab kev tiv taus tshuaj lom neeg, Silicon Carbide yog qhov kev xaiv zoo tshaj plaws. Ntawm qhov tod tes, Tungsten Carbide haum rau cov ntawv thov hnyav uas qhov kev tiv taus kev cuam tshuam yog qhov tseem ceeb.
Kev xaiv cov khoom siv lub ntsej muag foob yog qhov tseem ceeb rau kev ua kom muaj kev ua tau zoo tshaj plaws thiab lub neej ntev hauv kev ua haujlwm hauv kev lag luam.
Cov Lus Nug Feem Ntau
Qhov txawv tseem ceeb ntawm Silicon Carbide thiab Tungsten Carbide yog dab tsi?
Silicon Carbide ua tau zoo heev hauv kev tiv taus tshuaj lom neeg thiab kev siv kub siab, thaum Tungsten Carbide muaj kev tawv thiab kev cuam tshuam zoo dua. Txhua yam khoom siv haum rau ntau yam kev xav tau ntawm kev lag luam raws li cov yam ntxwv no.
Cov khoom siv twg pheej yig dua rau kev siv mus sij hawm ntev?
Txawm hais tias Silicon Carbide muaj tus nqi pib qis dua, Tungsten Carbide feem ntau siv tau ntev dua, ua rau txo cov nqi kho thiab hloov pauv raws sijhawm. Qhov kev xaiv nyob ntawm cov kev xav tau ntawm daim ntawv thov tshwj xeeb.
Puas siv tau Silicon Carbide hauv cov chaw muaj kev kub siab?
Yog, Silicon Carbide tuaj yeem tiv taus kev nyuaj siab, tab sis nws qhov brittleness yuav txwv nws cov txiaj ntsig hauv kev siv nrog kev co tshuab ntau zaus. Kev xav txog cov xwm txheej ua haujlwm yog qhov tseem ceeb.
Tungsten Carbide puas haum rau cov chaw muaj corrosive?
Tungsten Carbide tsis zoo rau cov chaw muaj zog acidic vim nws cov cobalt binder, uas tuaj yeem leach tawm. Rau cov ntawv thov corrosive, Silicon Carbide feem ntau yog qhov kev xaiv zoo dua.
Kuv yuav xaiv cov khoom siv foob rau kuv daim ntawv thov li cas?
Xav txog tej yam xws li kub, kev raug tshuaj lom neeg, kev tiv taus kev hnav, thiab kev ntxhov siab ntawm lub tshuab. Kev soj ntsuam cov yam no yuav pab txiav txim siab seb Silicon Carbide lossis Tungsten Carbide puas haum rau koj cov kev xav tau.
