A cikin samar da masana'antu na zamani, tsarin bututun ya zama kamar "jini" na jikin mutum, yana yin aiki mai mahimmanci na jigilar zafi mai zafi da kuma lalata. Thesilicon carbide (SiC) rufifasaha kamar sanya sulke na manyan sulke a kan waɗannan “tasoshin jini”, yana ba bututun ya fi ƙarfin matsewa, juriya, da juriya mai zafi. Ta yaya wannan shingen kariya da alama mai sauƙi ke kare kwanciyar hankali na aikin bututun?
1. Material Properties: The "haihuwa hazaka" na silicon carbide
Silicon carbide an san shi da "lu'u lu'u-lu'u na masana'antu", kuma tsarinsa na atomic crystal ne mai girma uku na cibiyar sadarwa wanda ya ƙunshi covalent bond tsakanin silicon da carbon, yana ba shi manyan kaddarorin guda uku:
1. Lu'u-lu'u taurin daraja (na biyu kawai zuwa lu'u-lu'u a cikin taurin Mohs), wanda zai iya tsayayya da yashwar barbashi
2. Inertness mai ƙarfi mai ƙarfi, mai juriya ga kafofin watsa labarai masu lalata kamar acid, tushe, da gishiri.
3. Excellent thermal kwanciyar hankali, rike tsarin kwanciyar hankali ko da a high yanayin zafi na 1350 ℃
Wannan kayan abu ya sa ya zama kyakkyawan kayan kariya don matsanancin yanayin aiki.
2. Tsarin kariya: Tsarin tsaro sau uku
Lokacin da rufin silicon carbide ya manne da bangon ciki na bututun, yana samar da matakan kariya da yawa:
Layer shamaki na jiki: lu'ulu'u masu yawa na silicon carbide suna keɓe matsakaici kai tsaye daga hulɗa da jikin bututun ƙarfe
Chemical barga Layer: forming wani m oxide fim ta passivation dauki, rayayye jure lalata
Wannan tsarin kariyar haɗin gwiwar yana ba da damar bututun don kiyaye amincin tsarin ko da a cikin yanayi mai tsauri kamar lalata mai ƙarfi, babban lalacewa, da yanayin zafin jiki.
3. Sirrin aiki na dogon lokaci: yuwuwar warkar da kai
Sabon bincike ya gano cewa siliki carbide yana da keɓantaccen ikon sake haɗa saman ƙasa ƙarƙashin takamaiman yanayin aiki. Lokacin da ɓarna na ƙanƙara ta faru, atom ɗin siliki na kyauta akan saman kayan za su sake tsarawa a cikin yanayin zafi mai zafi, wani sashi na gyara lahani. Wannan fasalin yana haɓaka rayuwar sabis na rufi sosai kuma yana rage mitar kulawa.
4. Amfanin da ba a iya gani: cikakken ƙimar rayuwa
Idan aka kwatanta da kayan rufi na gargajiya, rufin siliki na carbide yana kawo fa'idodin tattalin arziƙin ɓoye amma fa'idodin tattalin arziƙi ga masana'antun masana'antu ta hanyar rage adadin rufewa don kulawa, rage haɗarin matsakaicin gurɓataccen gurɓataccen iska, da tsawaita sake zagayowar maye gurbin bututun. Musamman a cikin fagagen sinadarai masu kyau da sabon shiri na kayan makamashi, ƙimar tabbatar da tsabtar kayan abu ya fi wahalar aunawa tare da sauƙin bayanai.
Tare da haɓaka fasahar masana'antu zuwa mafi inganci da abokantaka na muhalli, fasahar suturar silicon carbide tana tasowa daga "kariya ta musamman" zuwa "daidaitaccen tsari". Wannan bayani wanda ya haɗu da ilimin kimiyyar kayan aiki da basirar injiniya cikin shiru yana kiyaye "rayuwar rayuwa" na masana'antar zamani kuma ya zama muhimmiyar goyon bayan fasaha don inganta inganci da ingancin masana'antu.
