Thaum nws los txog rau silicon carbide ceramics, muaj ob lub ntsiab:Cov tshuaj tiv thaiv sib raug zoo silicon carbidethiab sintered silicon carbide. Thaum ob hom ceramics muaj qib siab ntawm kev ua haujlwm ntev thiab hnav tsis kam, muaj qee qhov sib txawv tseem ceeb ntawm ob.
Cia peb pib nrog cov tshuaj tiv thaiv kev sib raug zoo silicon carbide ceramics. Cov ceramics no nyob nruab nrab ntawm 85% thiab 90% silicon carbide thiab muaj qee qhov silicon. Lawv qhov ntsuas kub siab tshaj plaws yog 1380 ° C. Ib qho ntawm qhov zoo tshaj plaws ntawm cov tshuaj tiv thaiv-bonded silicon carbide ceramics yog tias lawv tuaj yeem ua kom haum rau qhov loj thiab cov duab. Qhov no ua rau lawv cov ntaub ntawv zoo tshaj plaws los tsim cov khoom tshwj xeeb thiab kev tshaj lij. Tsis tas li ntawd, qhov qis coefficient ntawm kev nthuav dav thiab kev hnav zoo heev ntawm cov ceramics ua rau lawv muaj kev xaiv nrov hauv kev lag luam mining cyclone.
Lub siab tsis muaj sintered silicon carbide muaj cov ntsiab lus siab dua ntawm silicon carbide, uas tuaj yeem ncav cuag ntau dua 99%, thiab qhov kub siab tshaj yog 1650 ° C. Ib coefficient ntawm expansion yog qhia thaum lub sij hawm sintering txheej txheem, uas ua rau pressureless sintered SiC zoo tagnrho rau manufacturing precision SiC qhov chaw. Vim nws cov high precision, pressureless sintered silicon carbide feem ntau yog siv los ua pwm thiab hnav-resistant precision qhov chaw.
Ntxiv nrog rau cov pwm precision thiab hnav qhov chaw, cov khoom siv high-end kiln rau kev lag luam chemical tuaj yeem ua kom zoo dua qhov kub thiab txias tsis kam ntawm pressureless sintered silicon carbide. Rau cov neeg uas tab tom nrhiav kom muaj txiaj ntsig zoo ntawm cov khoom siv hluav taws xob zoo rau lawv cov khoom siv tshuaj, tsis muaj zog sintered silicon carbide yog qhov kev xaiv zoo tshaj plaws.
Feem ntau, cov tshuaj tiv thaiv kev sib raug zoo thiab tsis muaj zog sintering ntawm SiC ceramics, txawm hais tias txhua tus muaj nws qhov zoo thiab qhov tsis zoo, yog qhov tsim nyog rau kev lag luam thiab kev siv sib txawv. Yog tias koj xav tau cov khoom lag luam tshwj xeeb lossis loj dua uas tuaj yeem tiv taus hnav, cov tshuaj tiv thaiv kev sib raug zoo silicon carbide ceramics yuav yog qhov kev xaiv zoo rau koj. Rau ntau qhov chaw me me uas yuav tsum tau tiv taus qhov kub thiab txias, tsis muaj zog sintered silicon carbide yuav yog qhov kev xaiv zoo dua. Tsis muaj teeb meem dab tsi ntawm silicon carbide ceramic koj xaiv, koj tuaj yeem ntseeg tau tias nws yuav muab cov kav ntev thiab kev ruaj khov uas koj qhov project xav tau.
