ISilicon Carbide (SiC) Isishwankathelo sePowder
I-Silicon carbide (i-SiC), eyaziwa ngokuba yi-carborundum okanye i-emery, yenye yezona zinto zisetyenziswa kakhulu kunye nezoqoqosho. I-SiC ifumaneka ngeendlela ezimbini: i-silicon carbide emnyama kunye ne-silicon carbide eluhlaza.
Inkqubo yeMveliso
I-SiC iveliswa ngokunyibilikisa isanti ye-quartz, i-petroleum coke, okanye i-coal tar, kunye nee-chips zokhuni kumaqondo aphezulu okushisa kwisithando somlilo. I-silicon carbide eluhlaza yenziwe ngokukodwa ngokunyibilikisa i-silicon dioxide ekumgangatho ophezulu kunye ne-petroleum coke, enetyuwa eyongeziweyo njengesongezo.
Iipropati kunye nezicelo
-Ubunzima:Iwa phakathi kwecorundum nedayimane.
-Amandla oomatshini:Iphakamileyo kune-corundum, i-brittle, kwaye ibukhali.
-Ukuqhuba:Unombane kunye ne-thermal conductivity ethile.
Ngenxa yezi propati, i-SiC ifanelekile kwizicelo ezifuna ukuhlala ixesha elide kunye nokulawulwa kwe-thermal. Isetyenziswa kakhulu kumashishini afana ne-abrasives, refractories, kunye ne-semiconductors.
Iimpawu zeSilicon Carbide
1. Ukwandiswa kweThermal ephantsi:Yehlisa utshintsho kubukhulu ngokuguquguquka kobushushu.
2. High Thermal Conductivity:Ukudlulisa ubushushu ngokufanelekileyo.
3. Ukumelana noxinzelelo lwe-Thermal:Yehlisa ukubakho koxinzelelo lwe-thermal.
4. Okugqwesileyo kweThermal Shock Resistance:Ukumelana nokutshintsha kobushushu obukhawulezayo.
5. Ukuchasa ukuMdla:Yomelela ngokuchasene nomonakalo wekhemikhali.
6. UkuNyamezelwa koBubushushu obugqithisileyo: Isebenza kakuhle kwiindawo ezibandayo kakhulu kunye nezishushu.
7. Ukumelana neCreep yobushushu obuphezulu:Ugcina uzinzo kunye namandla kumaqondo obushushu aphezulu.
I-Semicera inokwenza ngokwezifiso i-4N-6N i-silicon carbide powder ngokweemfuno zakho, wamkelekile ukuba ubuze.
