Thaum nws los txog rausilicon carbide ceramics, muaj ob hom tseem ceeb: reaction bonded thiab sintered. Txawm hais tias ob hom ceramics muaj cov qib siab ntawm kev ruaj khov thiab kev tiv thaiv kev hnav, muaj qee qhov sib txawv tseem ceeb ntawm ob qho.
Cia peb pib nrog cov khoom siv ua los ntawm cov khoom siv reaction bonded silicon carbide. Cov khoom siv no muaj li ntawm 85% thiab 90% silicon carbide thiab muaj qee cov silicon. Lawv qhov kub siab tshaj plaws yog 1380 ° C. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom siv ua los ntawm cov khoom siv reaction-bonded silicon carbide yog tias lawv tuaj yeem hloov kho kom haum rau qhov loj thiab cov duab. Qhov no ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom tshwj xeeb thiab kev tshaj lij. Tsis tas li ntawd, qhov coefficient qis ntawm kev nthuav dav thiab kev tiv thaiv kev hnav zoo ntawm cov khoom siv no ua rau lawv yog qhov kev xaiv nrov hauv kev lag luam mining cyclone.
Cov silicon carbide sintered uas tsis muaj siab muaj cov ntsiab lus ntau dua ntawm silicon carbide, uas tuaj yeem ncav cuag ntau dua 99%, thiab qhov kub siab tshaj plaws yog 1650 ° C. Ib qho coefficient ntawm kev nthuav dav tau qhia thaum lub sijhawm sintering, uas ua rau cov SiC sintered uas tsis muaj siab zoo tagnrho rau kev tsim cov khoom SiC uas raug. Vim nws qhov kev raug siab, cov silicon carbide sintered uas tsis muaj siab feem ntau siv los ua pwm thiab cov khoom raug uas tsis hnav tau.
Ntxiv rau cov pwm precision thiab cov khoom siv hnav, cov khoom siv kiln siab kawg rau kev lag luam tshuaj lom neeg tuaj yeem siv qhov zoo ntawm qhov kub tsis kam ntawm cov silicon carbide sintered tsis muaj siab. Rau cov neeg uas tab tom nrhiav cov raj xa cua sov zoo rau lawv cov khoom siv ua tshuaj lom neeg, cov silicon carbide sintered tsis muaj siab yog qhov kev xaiv khoom siv tau zoo.
Feem ntau, kev sib txuas ua ke thiab kev sib xyaw ua ke tsis muaj siab ntawm SiC ceramics, txawm hais tias txhua tus muaj nws qhov zoo thiab qhov tsis zoo, yog qhov tsim nyog rau ntau yam lag luam thiab daim ntawv thov. Yog tias koj xav tau cov khoom tshwj xeeb lossis loj dua uas tuaj yeem tiv taus kev hnav, kev sib xyaw ua ke silicon carbide ceramics yuav yog qhov kev xaiv zoo rau koj. Rau cov khoom me me uas yuav tsum tau tiv taus qhov kub siab, kev sib xyaw ua ke silicon carbide tsis muaj siab yuav yog qhov kev xaiv zoo dua. Txawm hais tias koj xaiv hom silicon carbide ceramic twg los xij, koj tuaj yeem ntseeg siab tias nws yuav muab qhov ruaj khov thiab kev ruaj khov uas koj qhov project xav tau.
