Silicon Carbide (SiC) Uhlolojikelele Powder
I-Silicon carbide (SiC), eyaziwa nangokuthi i-carborundum noma i-emery, ingenye yezinto ezisetshenziswa kakhulu futhi ezongayo. I-SiC itholakala ngezindlela ezimbili: i-silicon carbide emnyama ne-silicon carbide eluhlaza.
Inqubo Yokukhiqiza
I-SiC ikhiqizwa ngokuncibilikisa isihlabathi se-quartz, i-petroleum coke, noma i-coal tar, nama-wood chips emazingeni okushisa aphezulu esithandweni sokumelana. I-silicon carbide eluhlaza yenziwe ngokukhethekile ngokuncibilikisa i-silicon dioxide yekhwalithi ephezulu kanye ne-petroleum coke, nosawoti wengezwe njengesithako.
Izakhiwo Nezicelo
-Ubunzima:Iwa phakathi kwe-corundum nedayimane.
-Amandla Mechanical:Iphakeme kune-corundum, i-brittle, futhi ibukhali.
-Conductivity:Inokushintshwa okuthile kukagesi kanye ne-thermal.
Ngenxa yalezi zakhiwo, i-SiC ilungele izinhlelo zokusebenza ezidinga ukuqina nokuphathwa okushisayo. Isetshenziswa kakhulu ezimbonini ezinjengama-abrasives, ama-refractories, nama-semiconductors.
Izici ze-Silicon Carbide
1. Ukwandiswa Okuphansi Kokushisa:Yehlisa izinguquko kusayizi ngokushintshashintsha kwezinga lokushisa.
2. High Thermal Conductivity:Idlulisa kahle ukushisa.
3. Ukumelana Nokucindezeleka Okushisayo:Yehlisa amathuba okuba nengcindezi yokushisa.
4. Ukumelana Okuhle Kakhulu Kwe-Thermal Shock:Imelana nokushintsha kwezinga lokushisa okusheshayo.
5. Ukumelana Nokugqwala:Ihlala isikhathi eside ngokumelene nokulimala kwamakhemikhali.
6. Ukubekezelelana Kwamazinga Okushisa Kakhulu: Isebenza kahle kuzo zombili izindawo ezibanda kakhulu nezishisayo.
7. I-High-Temperature Creep Resistance:Igcina ukuzinza namandla emazingeni okushisa aphezulu.
I-Semicera ingenza ngokwezifiso i-4N-6N silicon carbide powder ngokwezidingo zakho, wamukelekile ukubuza.
