Muaj ib qho kev sib raug zoo ntawm qhov tsis kam ntawm cov nqi ntawm silicon carbide rods thiab kub, uas yog feem ntau tshwm sim nyob rau hauv qhov kev hloov ntawm cov resistivity ntawm silicon carbide rods nrog kub, tshwj xeeb tshaj yog thaum mus txog 800 degrees Celsius, lub resistivity qhia ib tug tig point, thiab ces maj mam. nce nrog qhov txuas ntxiv ntawm qhov kub thiab txias. Qhov kev hloov tsis-linear hauv kev tiv thaiv yog ib qho tseem ceeb ntawm silicon carbide rods, uas yog qhov tseem ceeb rau lawv daim ntawv thov thiab tsim.
Cov yam ntxwv ntawm kev sib txawv ntawm qhov sib txawv ntawm silicon carbon rods
Lub resistivity ntawm silicon carbide rods sai txo nrog nce kub nyob rau hauv lub chav tsev kub mus rau 800 degree C. Qhov no yog vim hais tias nyob rau hauv no kub ntau yam, lub resistivity ntawm silicon carbide rods hloov tsis zoo, lub ntsiab lus hais tias raws li qhov kub thiab txias, lub resistivity txo.
Tom qab tshaj 800 degree C, qhov kev tiv thaiv pib maj mam nce. Qhov no yog vim hais tias sab nraud ntawm qhov kub thiab txias, qhov resistivity ntawm silicon carbide pas nrig hloov mus rau ib qho txiaj ntsig zoo, txhais tau hais tias thaum qhov kub thiab txias tseem nce ntxiv, cov resistivity nce.
Kev txwv thiab kev tiv thaiv kev nyab xeeb rau kev siv cov silicon carbide rods
Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm silicon carbide rods tsis tuaj yeem tshaj 1450 degree C. Tshaj li qhov kub no, silicon carbide qws yuav muaj hnub nyoog sai thiab nws lub neej kev pab cuam yuav cuam tshuam loj heev.
Thaum siv, tus nqi kuj ntawm silicon carbide pas nrig yuav maj mam nce. Thaum nws tus nqi tsis kam nce mus rau plaub npaug ntawm qhov kev tiv thaiv tus nqi thaum pib siv, txawm tias lub pas nrig silicon carbide tsis raug kaw, nws lub neej kev pabcuam raug suav tias tau tas lawm.
Kev txiav txim siab hauv kev siv tswv yim
Thaum tsim ib lub kaw lus siv silicon carbide rods, nws yog ib qho tsim nyog yuav tau xav txog qhov kub thiab txias nyob ntawm cov yam ntxwv ntawm lawv qhov kev tiv thaiv thiab qhov tseem ceeb ntawm qhov sib txawv ntawm qhov kub thiab txias kom ntseeg tau tias kev nyab xeeb thiab kev ua haujlwm ntawm lub cev.
Txhawm rau kom muaj kev ua haujlwm zoo thiab kev nyab xeeb ntawm silicon carbide rods, qhov ntev ntawm qhov txias txias yuav tsum sib npaug rau lub thickness ntawm lub cub tawg phab ntsa ntxiv rau qhov ntev ntawm qhov txias kawg protruding los ntawm lub cub tawg phab ntsa. Qhov ntev txuas ntxiv ntawm qhov txias kawg yog 50-150mm.
Hauv cov ntsiab lus, muaj kev sib raug zoo tsis sib xws ntawm kev ua haujlwm ntawm silicon carbide rods thiab kub, uas yog ib qho tseem ceeb rau kev siv thiab tsim ntawm silicon carbide rods. Kev nkag siab txog qhov kev sib raug zoo no tuaj yeem pab tau zoo dua siv cov yam ntxwv ntawm silicon carbide rods, ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm lub cev. cov
