Ekusetshenzisweni kwemishini yezimboni, kukhona ingxenye enganakwa kalula kodwa ebalulekile - uphawu. Lufana "nendandatho yokuvala" yedivayisi, enesibopho sokuhlukanisa uketshezi lwangaphakathi namagesi, ukuvimbela ukuvuza. Uma uphawu seluhlulekile, lungathinta ukusebenza kahle kwedivayisi noma lubangele izingozi zokuphepha. Phakathi kwezinto eziningi zokuvala, i-silicon carbide ceramics kancane kancane iba "intandokazi entsha" emkhakheni wezimboni osezingeni eliphezulu ngenxa yezinzuzo zazo eziyingqayizivele.
Abanye abantu bangase babe nesithakazelo, ingabe izinto zobumba azibuthakathaka? Zingasetshenziswa kanjani ukwenza izivalo? Eqinisweni,izitsha zobumba ze-silicon carbidezihluke ngokuphelele ezitsheni nasezinkomishini ze-ceramic esizibona ekuphileni kwethu kwansuku zonke. Ziyizinto ze-ceramic ezithuthukisiwe ezenziwe ngezinqubo ezikhethekile, ezinobunzima obulandela idayimane kuphela. Izisimbiso ezenziwe ngazo ziqala ngokuxazulula inkinga yezinto zokuvala zendabuko "ezimelana nokuguguleka". Emishinini yesivinini esikhulu njengamaphampu amanzi nama-compressor, izisimbiso zidinga ukukhuhla ezinye izingxenye isikhathi eside, futhi izinto ezivamile zizoguguleka futhi ziguge maduze. Kodwa-ke, ukumelana nokuguguleka kwezisimende ze-silicon carbide kuvumela ukuthi "zinamathele ezigxotsheni zazo" isikhathi eside ngaphansi kwezimo zokusebenza ezinzima, okwandisa kakhulu impilo yenkonzo yemishini.
Ngaphezu kokumelana nokuguguleka, ukumelana nokushisa okuphezulu kanye nokumelana nokugqwala nakho kuyizinto ezikhethekile ze-silicon carbide ceramic seals. Ezimbonini ezifana namakhemikhali kanye ne-metallurgical, imishini ivame ukuxhumana ne-media egqwalisayo njenge-acid enamandla kanye ne-alkalis, futhi ingamelana namazinga okushisa angamakhulu noma ngisho nezinkulungwane zama-degree Celsius. I-metal seals yendabuko ithambekele ekugqwaleni nasekuguquguqukeni kwamazinga okushisa aphezulu, kuyilapho i-rubber seals ithambisa futhi yehluleka kwamazinga okushisa aphezulu. I-silicon carbide ceramics ayikwazi nje ukumelana nokuguguleka kwezinto ezahlukahlukene zamakhemikhali, kodwa futhi igcina ukusebenza okuzinzile ezindaweni ezishisa kakhulu, ngaphandle kokuguquguquka, ukuqhekeka nezinye izinkinga, okunikeza isiqinisekiso sokusebenza okuphephile kwemishini ngaphansi kwezimo ezimbi kakhulu.
Kuyafaneleka ukusho ukuthi izivalo ze-silicon carbide ceramic nazo zinezici "ezilula" kanye "nokungqubuzana okuphansi". Ubuningi bayo buncane kunobensimbi, okunganciphisa isisindo sonke semishini; Ngesikhathi esifanayo, ubuso bayo bubushelelezi futhi i-coefficient yokungqubuzana iphansi, okunganciphisa ukusetshenziswa kwamandla ngesikhathi sokusebenza futhi kusize imishini ukuthi ifinyelele ukusebenza kahle kakhulu. Lokhu ngokungangabazeki kuyisici esivelele kakhulu ezimbonini zanamuhla eziphishekela ukonga amandla nokunciphisa ukusetshenziswa kwawo.
Kusukela ezimfanelweni ezingabonakali kuya “kumuntu obalulekile” osekela ukusebenza okuzinzile kwemishini yezimboni ephezulu, izitsha zobumba ze-silicon carbide zibonisa amandla “embonini eshintsha izinto”. Ngokuthuthuka okuqhubekayo kwezidingo zokusebenza kwemishini emkhakheni wezimboni, lesi sitsha sobumba, esihlanganisa izinzuzo ezifana nokumelana nokuguguleka, ukumelana nokushisa okuphezulu, kanye nokumelana nokugqwala, sizodlala indima ebalulekile emikhakheni eminingi esikhathini esizayo futhi sibe “umqaphi” wangempela wemishini yezimboni.
