Sisebenzisa amakhukhi ukuthuthukisa ulwazi lwakho. Ngokuqhubeka uphequlula le sayithi, uyavuma ukusebenzisa kwethu amakhukhi. Ulwazi Olwengeziwe.
Ngokwemvelo yawo, amadivayisi ahloselwe ukusetshenziswa kwezokwelapha kumele ahlangabezane nezindinganiso zokuklama nezokukhiqiza eziqinile kakhulu. Ezweni elimatasa kakhulu ngecala kanye nokujeziswa ngokulimala komzimba noma umonakalo obangelwe yiphutha lezokwelapha, noma yini ethinta noma efakwe ngokuhlinzwa emzimbeni womuntu kumele isebenze njengoba kuhlosiwe futhi akumelwe yehluleke.
Inqubo yokuklama nokukhiqiza amadivayisi ezokwelapha ingenye yezinkinga zesayensi nobunjiniyela eziyinkimbinkimbi kakhulu ezizoxazululwa embonini yezokwelapha. Njengoba kunezinhlobo eziningi kangaka zezicelo, amadivayisi ezokwelapha eza ngazo zonke izinhlobo nobukhulu ukuze enze imisebenzi eyahlukahlukene, ngakho ososayensi nonjiniyela basebenzisa izinto ezahlukahlukene ukuze bahlangabezane nezidingo zomklamo eziqinile kakhulu.
Insimbi engagqwali ingenye yezinto ezisetshenziswa kakhulu ekukhiqizeni amadivayisi ezokwelapha, ikakhulukazi insimbi engagqwali engu-304.
Insimbi engagqwali engu-304 iqashelwa emhlabeni wonke njengenye yezinto ezifanele kakhulu zokukhiqiza amadivayisi ezokwelapha ezinhlelo zokusebenza ezahlukahlukene. Eqinisweni, iyinsimbi engagqwali esetshenziswa kakhulu emhlabeni namuhla. Ayikho enye insimbi engagqwali enikeza izinhlobo ezahlukene zezimo, ukuqedwa kanye nezinhlelo zokusebenza. Izakhiwo zensimbi engagqwali engu-304 zinikeza izakhiwo zezinto ezihlukile ngentengo encintisanayo, okwenza kube ukukhetha okunengqondo kwemininingwane yemishini yezokwelapha.
Ukumelana nokugqwala okuphezulu kanye nokuqukethwe okuphansi kwekhabhoni yizici ezibalulekile ezenza insimbi engagqwali engu-304 ifaneleke kakhulu ekusetshenzisweni kwezokwelapha kunezinye izinhlobo zensimbi engagqwali. Amadivayisi ezokwelapha awasabelani ngamakhemikhali nezicubu zomzimba, izinto zokuhlanza ezisetshenziswa ukuwahlanza, kanye nokuguga okunzima, okuphindaphindiwe okwenziwa amadivayisi amaningi ezokwelapha, okusho ukuthi insimbi engagqwali yohlobo lwe-304 iyinto efanelekile ekusetshenzisweni kwezicelo zasesibhedlela, zokuhlinzwa, kanye nezezimo eziphuthumayo. , phakathi kwezinye.
Insimbi engagqwali engu-304 ayigcini nje ngokuba namandla kodwa futhi kulula kakhulu ukuyicubungula futhi ingadonswa ngokujulile ngaphandle kokuyinamathisela, okwenza i-304 ibe yindawo ekahle yokwenza izitsha, amasinki, amabhodwe kanye nezitsha ezahlukene zezokwelapha nezinto ezingenalutho.
Kukhona futhi izinhlobo eziningi ezahlukene zensimbi engagqwali engu-304 enezakhiwo ezithuthukisiwe zezinto ezisetshenziswayo ezithile, njengenguqulo ye-304L enamandla aphansi lapho kudingeka khona ukushintshwa kwamandla aphezulu. Imishini yezokwelapha ingasebenzisa i-304L lapho ukushintshwa kumele kumelane nochungechunge lokushaqeka, ukucindezeleka okuqhubekayo kanye/noma ukuguqulwa, njll. Insimbi engagqwali engu-304L nayo iyinsimbi ephansi yokushisa, okusho ukuthi ingasetshenziswa ezisetshenziswayo lapho umkhiqizo kumele usebenze emazingeni okushisa aphansi kakhulu. Ezindaweni ezigqwala kakhulu, i-304L iphinde inikeze ukumelana okukhulu nokugqwala kwe-intergranular kunezinhlobo zensimbi engagqwali ezifanayo.
Ukuhlanganiswa kwamandla aphansi okukhiqiza kanye nekhono eliphezulu lokunwebeka kusho ukuthi insimbi engagqwali yohlobo lwe-304 ifaneleka kahle ekwakheni izimo eziyinkimbinkimbi ngaphandle kokunamathela.
Uma kudingeka insimbi engagqwali eqinile noma eqinile ekusetshenzisweni kwezokwelapha, i-304 ingaqiniswa ngokusebenza okubandayo. Uma iqiniswa, izinsimbi ezingu-304 kanye ne-304L ziqiniswa kakhulu futhi zingakhiwa kalula, zigotshwe, zidonswe ngokujulile noma zenziwe. Kodwa-ke, i-304 iyaqina ngokushesha futhi ingadinga ukuqiniswa okwengeziwe ukuze kuthuthukiswe ukuqiniswa ukuze kuqhutshekwe nokucutshungulwa.
Insimbi engagqwali engu-304 isetshenziswa kabanzi ezinhlotsheni ezahlukene zezimboni nezasekhaya. Embonini yamadivayisi ezokwelapha, i-304 isetshenziswa lapho ukumelana nokugqwala okuphezulu, ukwakheka okuhle, amandla, ukunemba, ukuthembeka kanye nokuhlanzeka kubaluleke kakhulu.
Kwezinsimbi ezingagqwali zokuhlinzwa, kusetshenziswa kakhulu izinhlobo ezikhethekile zensimbi engagqwali, ezingama-316 kanye nama-316L. Ngezakhi zokuxuba ze-chromium, i-nickel kanye ne-molybdenum, insimbi engagqwali inikeza ososayensi nodokotela abahlinzayo izimfanelo eziyingqayizivele nezithembekile.
Isexwayiso. Kuyaziwa ukuthi ezimweni ezingavamile, amasosha omzimba womuntu ayasabela kabi (ngokwesikhumba nangokwesistimu) kokuqukethwe kwe-nickel kwezinye izinsimbi ezingagqwali. Kulesi simo, i-titanium ingasetshenziswa esikhundleni sensimbi engagqwali. Kodwa-ke, i-Titanium inikeza ikhambi elibiza kakhulu. Ngokuvamile, insimbi engagqwali isetshenziselwa izimila zesikhashana, kuyilapho i-titanium ebiza kakhulu ingasetshenziswa izimila ezihlala njalo.
Isibonelo, ithebula elingezansi libala ezinye zezinhlelo zokusebenza ezingaba khona zamadivayisi ezokwelapha ensimbi engagqwali:
