Ukuqina Okuphakeme Nge-Silicon Carbide Tube

I-Silicon carbide ime njengeqhawe elingashiwongo kuma-industrial forges. Ukufakazela ukuqina kwayo kumazinga okushisa, amakhemikhali, futhi ubunzima bemishini bubaluleke kakhulu kokuphila okusebenzayo kwemishini – kanye ne-karicon carbide yenza iqhawe elingavinjekayo la madivayisi abilayo.

Amashubhu e-SiC anikeza izinzuzo eziningi eziwenza abe yinketho ekhethwayo yezinto zokukhiqiza amandla kanye namashethi okuvikela e-thermocouple., kufaka phakathi ukuvikelwa kwe-thermocouple sheath. Lesi sihloko sizogqamisa izici zabo ezibalulekile.

Ukumelana nokugqwala

Amashubhu e-silicon carbide afakazele ukubaluleka kwawo njengempahla yezimboni enokuqina okuphezulu, ukuvikela amabhizinisi ekushiseni, amakhemikhali nokucindezeleka kwemishini ukuze kunwetshwe isikhathi sokusebenza kanye nezindleko zokunakekela eziphansi. Ngenxa yalokho, amabhizinisi ahlomula ngesikhathi esincishisiwe ukuze enze inzuzo eyengeziwe.

I-Sintered Silicon Carbide ingenye yezinsimbi eziqinile zezimboni, ukuziqhayisa ngobulukhuni obuqhathaniseka nedayimane. Lokhu kuyenza ifanelekele izindawo ezinokhahlo nezimboni ezibandakanya amazinga okushisa aphezulu namakhemikhali anokhahlo., kanye nokuhlinzeka ngezinzuzo ze-thermal conductivity nokuba ne-modulus ephezulu ye-Young evumela ukuthi imelane nokuhlukahluka kwezinga lokushisa ngaphandle kokuqhekeka noma ukuphuka ngaphansi kwengcindezi..

Amashubhu e-silicon carbide angamelana nokuchayeka kuma-asidi amaningi (hydrochloric, i-sulfuric kanye ne-nitric acid) kanye nezisekelo (izisekelo ze-phosphoric ne-potassium), ngaphezu kwezincibilikisi eziningi. Kanjalo, benza imigqa ephikisayo efanelekile yeziko kanye neziko.

I-Thermal Shock Resistance

I-silicon carbide ivele njengomholi phakathi kwezinto ezithuthukisiwe zezimboni. Kusukela ku-aerospace kuya ekukhiqizeni amandla kanye nokukhiqizwa kwe-semiconductor, I-silicon carbide ime ngokumelene namazinga okushisa aphezulu kanye nokuhlaselwa kwamakhemikhali ngomusa, ukuhlinzeka ngesimo kulezi zimboni nokunye.

Ukwakheka kwe-lattice ye-SiC yamabhondi e-carbon ne-silicon kubangela izici ezihlukile njengokuqina okukhulu namandla emishini., ukuminyana okuphansi kanye ne-elastic modulus, ukungabi nalutho, ukunwetshwa okuphansi kwe-thermal kanye ne-high conductivity yokushisa – izakhiwo ezihlanganisa ukumelana nokushaqeka okushisayo.

I-silicon carbide ceramic, enobulukhuni obufana nedayimane, inamandla okumelana nezindawo ezinokhahlo ezinobunzima bayo kanye nempilo yesikhathi eside. Kanjalo, lokhu kuyenza ifanelekele ukusetshenziswa njengama-nozzles of spray, ukudubula imibhobho yokuqhuma kanye nezingxenye ze-cyclone, lapho izinga lazo lizivumela ukuthi zimelane nezimo eziqhumayo ngempumelelo. Ngaphezu kwalokho, amashubhu e-silicon carbide ceramic aziqhenya ngezimpilo zesevisi ende ngokumangazayo ayizinketho ezikhethwayo kuzo zonke izimboni eziningi ngenxa yale khwalithi..

Ukumelana okushisa kakhulu

Amashubhu e-silicon carbide ayingxenye ebalulekile ezindaweni ezishisa kakhulu. Kusukela ekuqhumeni kwesithando somlilo kuya ekuvikeleni amashethi e-thermocouple, amashubhu e-silicon carbide anikeza ukuqina okungenakuqhathaniswa kanye nokunciphisa izindleko zesikhathi eside okudlula izinto zendabuko futhi kunciphise izindleko zokulungisa ngokuhamba kwesikhathi..

I-Silicon Carbide (SC) i-ceramic yezimboni ehlanganyela izinto eziningi ezifana nedayimane. NgeModulus Yentsha ephezulu kakhulu namandla akhethekile nokuzinza kobukhulu, I-SC inezakhiwo ezinhle ezibonakalayo ezingasetshenziswa ezinqubweni zokukhiqiza.

Izinto zokuvikela ukumelana nokushisa ezifana negwebu le-polyurethane zinikeza ukufakwa kwe-insulation ngokumelene nokushaqeka kokushisa, okwenza kube yisinqumo esifanele ukusetshenziswa eziko nakwezinye izinhlelo zokufudumeza nokupholisa. Ngaphezu kwalokho, izinga layo eliphezulu le-thermal conductivity linika amandla ukudluliswa kokushisa okusebenzayo okuhunyushwa ekongeni amandla okubalulekile kanye nezinyathelo eziphansi zekhabhoni.

Ukumelana ne-Abrasion

I-SiC iyimpahla yezimboni evelele eyaziwa ngamandla ayo nokuqina. Ingxenye ebalulekile ezitshalweni zamandla, izikhungo zokucubungula amakhemikhali, nezinye izindawo eziningi zokukhiqiza ngokufanayo – izimfanelo zayo zemvelo zokushisa okuphezulu kwe-thermal conductivity, Amandla Omshini, ukumelana nokugqwala kanye nokwanda okuphansi kokushisa yikona okuqinise isikhundla sako phakathi kwezitsha zobumba ze-ceramic zezimboni.

Ukusebenzisa izinqubo ezithuthukisiwe ezifana ne-reaction sintering kanye ne-pressless sintering, abakhiqizi bakhiqiza amashubhu e-ceramic e-Sintered SiC ane-microstructure efanayo kanye ne-porosity ephansi besebenzisa izindlela zesimanje ezifana ne-reaction sintering.. Lawa mashubhu ane-coefficient ephansi kakhulu yokwanda okushisayo emazingeni okushisa aphezulu kuyilapho ekwazi ukumelana nokugqwala okuvela kumakhemikhali ahlukahlukene anolaka..

Amashubhu e-SSiC aqhosha ngezilinganiso zobulukhuni be-Mohs eziqhathaniswa nedayimane, ukubenza baqine kakhulu futhi bafanele izinhlelo zokusebenza eziningi ezahlukene. Iyakwazi ukumelana nokulimala ngenxa yokuhuzuka nokuguguleka, Amashubhu e-SSiC enza ukukhetha okuhle kakhulu kwempahla yokudubula imibhobho yokuqhuma kanye nezingxenye zesiphepho kanye nokunikeza ukumelana okukhulu nama-asidi..
