I-silicon carbide ityhubhu yokukhusela
Kumashishini apho iimeko ezinzima zisongela imfezeko yezixhobo,i-silicon carbide (SiC) imibhobho yokukhuselazivela njengesisombululo esisisiseko. Ngokungafaniyo nezixhobo eziqhelekileyo zokukhusela, iityhubhu ze-SiC zidibanisa isayensi yezinto eziphambili kunye nobunjineli obuqinileyo ukukhusela izixhobo ezibalulekileyo kunye neenkqubo.
1. Ukukhuselwa okungahambelaniyo kwiiMeko ezinoButshaba
Iityhubhu zokukhusela ze-SiC zisebenza njengomgca wokuqala wokukhusela kwiindawo apho ukungaphumeleli kungeyona inketho:
(1) Ukhuselo lweThermal: Ukumelana namaqondo obushushu azinzileyo ukuya kuthi ga kwi-1600 ° C, izinzwa zokukhusela, ii-thermocouples, okanye iiprobes ezivela kwisinyithi esityhidiweyo, amadangatye kunye neplasma.
(2) Ukungakhuseleki kweChemical: Ukuxhathisa ukubola kwi-asidi (umz. isulfure, i-hydrochloric), i-alkalis, kunye neegesi ezisebenzayo ezifana neklorine okanye i-sulfur oxides.
Ukumelana ne-Abrasion: Khusela kumasuntswana akhukulisekileyo kwiibhedi ezimanzi, izitshizi zegesi zamalahle, okanye imisebenzi yasemigodini.
2. Ukuchaneka kunye nokuzinza kwiMilinganiselo ebalulekileyo
Kwiinkqubo eziphezulu zoshishino, ukuchaneka kubaluleke kakhulu. Iityhubhu ze-SiC zongeza ukuthembeka ngoku:
(1) Ukunciphisa ukungenelela koMqondiso: iipropati ezingaqhubekiyo zithintela ukuphazamiseka kwe-electromagnetic kwi-electronic sensors.
(2) Ukuzinza kwe-Thermal: I-Deformation ye-thermal ekufutshane ne-zero iqinisekisa ukulungelelaniswa okuhambelanayo kunye nokuchaneka komlinganiselo phantsi kokutshintsha ngokukhawuleza kweqondo lokushisa.
(3) I-Gas-Tight Integrity: Isakhiwo esingenakunyakaziswa sithintela ukungena kwegesi, kubalulekile kwiinkqubo ze-vacuum okanye i-atmospheres elawulwayo.
3. Ukunika amandla i-Next-Generation Technologies i-SiC iityhubhu zokukhusela zivula izinto ezintsha kwiinkalo ezivelayo:
(1) UQoqosho lweHydrojeni: Khonza njengeesheaths ezihlala zihlala kwi-sensors kwimveliso ye-hydrogen, ukugcinwa, kunye neeseli zepetroli, ukuxhathisa i-embrittlement kunye noxinzelelo oluphezulu lwe-H₂.
(2) Ukwenziwa kweSemiconductor: Khusela i-optical sensors kunye ne-thermal sensors kwi-CVD (i-Chemical Vapor Deposition) ii-reactors ezivela kwi-precursors ezonakalisayo njenge-silane okanye i-ammonia.
(3) Uphononongo lweSithuba: Isixhobo seShield kwiinjini zerokethi kunye neeprobe zeplanethi ukusuka kwimitha ye-thermal egqithisileyo kunye nemitha ye-cosmic.
4. Iindleko-zobuchule ngokuPhila ixesha elide
Ngelixa iityhubhu ze-SiC zineendleko eziphezulu zangaphambili, izibonelelo zabo zomjikelo wobomi zichaza ixabiso kwakhona:
(1) Ukunciphisa ixesha lokuphumla: Intsimbi ye-Outlast okanye enye i-quartz nge-4-6x kwimimiselo ye-abrasive okanye ene-acidic, ukunciphisa ukugcinwa okungacwangciswanga.
(2) IiMfuno zeZero zokugquma: Ngokungafaniyo neentsimbi ezifuna i-coatings ezikhuselayo, iipropathi ze-SiC zendalo zisusa iindleko zonyango oluhlala lukhona.
(3) Ukusebenziseka kwakhona: Sinda kwimijikelo yenkqubo emininzi kwizicelo ezinje ngesinyithi okanye ukwenza iglasi ngaphandle kokuthotywa.
5. Ukulungelelaniswa kweeMfuno eziZodwa
Iityhubhu zokukhusela ze-SiC ziqhelana nemingeni ye-niche ngobunjineli obulungiselelwe:
(1) Uyilo lweHybrid: Dibanisa kunye neentsimbi okanye iiseramikhi kwiiassembly ezinemisebenzi emininzi (umz. izihlanganisi ezinemisonto, iiflange).
(2) Uguqulo loMphezulu: Ingaphakathi elikhazimlisiweyo losetyenziso lwe-optical application okanye umphandle owenziwe ngothungelwano ukomeleza ukulahla ubushushu.
(3) Ubungakanani Ukuguquguquka: Yenziwe ukusuka kwiimilimitha (ielebhu zesikali se-reactors) ukuya kwiimitha (iikhilni zamashishini).
6. Ulungelelwaniso oluzinzileyo
Iityhubhu ze-SiC zixhasa iinkqubo zemizi-mveliso eco-friendly:
(1) Ugcino lwamandla: Ukusebenza okuphezulu kwe-thermal kunciphisa ukusetyenziswa kwamafutha eziko ukuya kuthi ga kwi-20% xa kuthelekiswa nezikhuselo zentsimbi.
（2）Unciphiso lweNkunkuma: Ubomi benkonzo ende bucutha inkunkuma yempahla ekutshintshweni rhoqo.
(3) Ukunciphisa ubutyhefu: Ukuphelisa imfuneko yeengubo ezinobungozi (umzekelo, ii-alloys ezisekelwe kwi-nickel) kwiindawo ezidliwayo.
I-Shandong Zhongpeng Special Ceramics Co., Ltd yenye yezona zisombululo zikhulu ze-silicon carbide zeceramic ze-ceramic e-China. I-ceramic yobugcisa be-SiC: Ubunzima be-Moh yi-9 (ubunzima be-Moh entsha yi-13), kunye nokumelana okugqwesileyo kukhukuliseko kunye ne-corrosion, i-abrasion egqwesileyo - ukuxhathisa kunye ne-anti-oxidation. Ubomi benkonzo yemveliso ye-SiC yi-4 ukuya kwamaxesha ama-5 ubude ngaphezu kwe-92% yezinto ze-alumina. I-MOR ye-RBSiC yi-5 kumaxesha e-7 ye-SNBSC, ingasetyenziselwa imilo enzima ngakumbi. Inkqubo yekoteyishini ikhawuleza, ukuhanjiswa kuthenjisiwe kwaye umgangatho ungowesibini. Sihlala sizingisa ukucela umngeni kwiinjongo zethu kwaye sibuyisele iintliziyo zethu kuluntu.
