Kev laus li qub ntawm silicon carbide rods yog hais txog qhov ua haujlwm tsis tu ncua thiab qeeb qeeb, nrog rau kev pab cuam lub neej ntev tshaj 2000 teev nyob rau hauv cov kev ua haujlwm ntsuas. Kev tiv thaiv nrawm nrawm, cua sov attenuation thiab tsis txaus rau qhov cub kub hauv lub sijhawm luv luv yog qhov txawv txav nrawm nrawm, uas yog qhov mob tshwm sim ntawm kev lag luam kiln. Kab lus no xaus cov laj thawj tseem ceeb thiab cov phiaj xwm kev daws teeb meem zoo.
1. Qhov tseem ceeb ntawm kev laus sai
1. Tsawg-kub Oxidation: Ntev- lub sijhawm ua haujlwm ntawm 200-800℃thaj chaw txaus ntshai ua rau SiC pulverization thiab oxide txheej txheej, ua rau muaj zog tiv taus, yog thawj qhov ua rau muaj kev laus sai.
2. Tshaj - kub dhau: Kev ua haujlwm tsis tu ncua dhau 1450℃ntsuas qhov kub thiab qhov kub ntawm qhov kub siab ua kom puas cov qauv siv lead ua thiab ua kom cov khoom tsis zoo.
3. Atmospheric Corrosion: Acid-paj pa roj, sulfur vapor, hlau vapor thiab noo noo nyob rau hauv lub cub tawg erode cua sov matrix.
4. Kev xaim tsis raug & Kev tu vaj tse: Kev sib xyaw ua ke ntawm cov pas nrig tshiab thiab qub, tsis sib haum ua haujlwm; tsis muaj voltage regulator, impulse tam sim no puas; plua plav scaling ua rau cua sov tsis sib xws.
5. Inferior Raw Khoom: Low-density base body and unqualified sintering craft lead to poor anti-oxidation and anti-corrosion performance.
2. Kev Txhim Kho & Kev Kho Kom Zoo Dua
① Kev Tswj Kub Kub: nrawm dhau 200-800℃oxidation cheeb tsam; txwv kev ua hauj lwm kub nyob rau hauv rated range; txais yuav cov txheej txheem cua sov / cua txias thiab txo qis pib-nres nquag.
② Standard Circuit Design: Hloov SiC rods nyob rau hauv ib batch nrog matched kuj; txwv tsis pub siv cov khoom tshiab thiab qub; equip professional voltage regulating txee.
③ Kev Kho Kom Haum Ua Haujlwm: Txais siab- ntom ntom recrystallized los tiv thaiv- cov pas nrig rau qhov chaw ntub dej thiab corrosive; ntxuav cov pas nrig saum npoo thiab lub cub tawg tsis tu ncua.
④ Cov Khoom Txhim Kho: Xaiv siab -purity & siab- ntom ntom sintered silicon carbide rods los txhim kho oxidation tsis kam thiab thermal shock resistance.
Cov ntsiab lus: 90% ceev kev laus tsis yog cov khoom tsis zoo. Kev ua haujlwm zoo, kev tswj xyuas qhov kub thiab qhov kev xaiv zoo tuaj yeem txuas ntxiv kev pab cuam lub neej los ntawm 40% -60%.
