Ngokuthuthuka okuqhubekayo kwezimboni nobuchwepheshe, izinto eziningi ezisetshenziswa ezindaweni ezinokushisa okuphezulu zibhekene nezinselele ezinzima.Ngaphansi kwezimo ezinjalo, izimbotshana ezimelana nezinga lokushisa eliphezulu ziye zaba ubuchwepheshe obubalulekile obunganikeza ukuvikelwa okushisayo okusebenzayo kwezinto ezihlukahlukene futhi kuqinisekise ukuzinza nokuqina kwazo ezindaweni ezishisa kakhulu.
I-high-temperature resistant coating iyi-coat eklanywe ngokukhethekile enokumelana okuhle kakhulu nokushisa okuphezulu.Ingakwazi ukumelana namazinga okushisa adlulele ukusuka kumakhulu ambalwa amadigri Celsius kuya ezinkulungwaneni zamadigri Celsius futhi igcine izici zayo ezibonakalayo nokubukeka kuzinzile isikhathi eside.Lokhu kwenza izimbobo ezimelana nezinga lokushisa eliphezulu zibe yinketho yokuqala ezimbonini eziningi, ikakhulukazi emkhathini, kumakhemikhali kaphethiloli, ukukhiqiza izimoto kanye nokuphehla ugesi.
Esinye sezici eziyinhloko zezingubo zokumelana nokushisa okuphezulu yi-conductivity yabo enhle kakhulu yokushisa.Ingakwazi ukumunca ngokuphumelelayo futhi iqhube ukushisa okuvela ebusweni bento eboshiwe, igcine izinga lokushisa lezinto ezimboziwe liphansi kunezinga lokushisa elizungezile, ngaleyo ndlela yehlise ngempumelelo ingozi yokugqwala nokuguga.
Ukwengeza, izigqoko eziphikisana nokushisa okuphezulu nazo zinezakhiwo ezinhle kakhulu ze-antioxidant, ezingavimbela i-oxidation yezinto eziboshwe emazingeni okushisa aphezulu kanye nokwakhiwa kwemifantu eshisayo.Izembatho ezimelana nokushisa okuphezulu zinezinhlobonhlobo zezicelo.Ingasetshenziselwa ukuvikela izinto ezihlukahlukene zensimbi nezingezona ezensimbi, njengensimbi, i-aluminium alloys, i-ceramics, njll., esebenza "njengesihlangu esishisayo".Zingagqunywa kumapayipi, ama-boilers, iziko, izinjini, izishintshi zokushisa nezinye izinto zokunciphisa ngokuphumelelayo ukulahlekelwa ukushisa, ukuthuthukisa ukusebenza kahle kwamandla, nokwandisa impilo yesevisi yemishini.
Ngaphezu kwalokho, izigqoko ezimelana nokushisa okuphezulu nazo zinokuguquguquka okuhle kwemvelo.Ngokuvamile basebenzisa ubuchwepheshe bokuvikela umlilo obungashintshi, obunganciphisa ukusabalala komlilo kanye nokuvela kwezingozi zokuphepha ngokuvikela umlilo okuphumelelayo kanye nokuhlukaniswa okushisayo.Ngesikhathi esifanayo, zivame ukuhlangabezana nezidingo zokuvikelwa kwemvelo, okuzenza zisetshenziswe kabanzi ezindaweni ezikhululekile neziphephile zasendlini.
Ngamafuphi, izinga lokushisa eliphezuluI-e resistant coatings, njengento ebalulekile yokuvikela, idlala indima ebalulekile ezindaweni ezishisa kakhulu.Banikeza isivikelo esisebenzayo sokushisa ngokumelene nokuguga kwezinto ezibonakalayo, i-oxidation kanye nokuqhekeka okushisayo.Ngokunciphisa ukulahlekelwa kwamandla kanye nokuthuthukisa ukusebenza kwemishini, ukunamathela okumelana nezinga lokushisa eliphezulu kuletha izinzuzo ezibalulekile zezomnotho nezemvelo ezimbonini ezihlukahlukene.Kungakhathaliseki ukuthi ku-aerospace, amandla noma ezinye izimboni, ama-coatings amelana nezinga lokushisa eliphezulu anguzakwethu othembekile ekuvikeleni izinto.
