Tsare-tsare don amfani da sandunan siliki na carbide don tanderun lantarki na gwaji
Kariya don amfani da sandunan siliki carbide don na’urorin lantarki na gwaji
1. Lokacin amfani da tanderun lantarki, zafin wutar lantarki bai kamata ya wuce yawan zafin jiki na dogon lokaci ba don kauce wa lalacewa ga kayan dumama. An haramta zuba abubuwa masu ƙonewa iri-iri da narkakken karafa a cikin tanderun.
2. Sanda na silikon carbide yana da wuya kuma yana da rauni, don haka a kula yayin lodawa da saukewa.
3. Ya kamata a adana sandunan carbide na silicon a cikin busasshen wuri don hana lalacewar ƙarshen aluminum-plated saboda danshi.
4. Narkar da KOH, NaOH, Na2CO3 da K2CO3 sun lalata SiC a zazzabi mai zafi. Za a lalata sandunan siliki na carbide a cikin hulɗa da alkali, ƙananan ƙarfe na ƙasa, sulfates, borides, da dai sauransu, don haka kada a tuntube su da sandunan siliki carbide.
5. Waya na siliki carbide sanda ya kamata a kusa da lamba tare da farin aluminum shugaban a sanyi karshen sandar don kauce wa walƙiya.
6. Sandar carbide na silicon yana amsawa tare da Cl2 a 600 ° C kuma yana amsawa da tururin ruwa a 1300-1400 ° C. Sanda na siliki carbide ba a sanya oxidized a kasa 1000 ° C, kuma yana da muhimmanci oxidized a 1350 ° C, a 1350-1500 ° C. An kafa fim ɗin kariya na SiO2 a tsakanin kuma yana manne da saman sandar siliki carbide don hana SiC daga ci gaba da oxidize.
7. Ƙimar juriya na sandar siliki na siliki yana ƙaruwa yayin da lokacin amfani da sandar silikon carbide ya karu, kuma abin da ya faru shine kamar haka:
SiC + 2O2 = SiO2 + CO2
SiC + 4H2O = SiO2 + 4H2 + CO2
Mafi girman abun ciki na SiO2, mafi girman ƙimar juriya na sandunan siliki carbide. Sabili da haka, tsoffin sandunan molybdenum na siliki ba za a iya haɗa su ba, in ba haka ba ƙimar juriya ba za ta kasance ba daidai ba, wanda ba shi da kyau ga filin zafin jiki da rayuwar sabis na igiyoyin siliki carbide.
