Emkhakheni wezimboni wanamuhla, izitsha zobumba ze-silicon carbide zaziwa ngokuthi "izikhali zempi" futhi seziyinto ebalulekile ezindaweni ezidlulele ngenxa yamandla azo aphezulu, ukumelana nokushisa okuphezulu, nokumelana nokugqwala. Kodwa abantu abaningi abakwazi ukuthi umndeni we-silicon carbide ceramic empeleni unamalungu amaningi, futhi izinqubo ezihlukene zokulungiselela zibanikeza "ubuntu" obuyingqayizivele. Namuhla sizokhuluma ngezinhlobo ezivame kakhului-silicon carbide ceramicsfuthi iveze izinzuzo eziyingqayizivele zokusabela sintered silicon carbide, ubuchwepheshe obuyinhloko bamabhizinisi.
1, "Abazalwane Abathathu" beSilicon Carbide Ceramics
Ukusebenza kwe-silicon carbide ceramics kuncike kakhulu enqubweni yayo yokulungiselela. Okwamanje kunezinhlobo ezintathu ezijwayelekile:
1. I-silicon carbide engacindezeli
Ngokubumba ngokuqondile i-silicon carbide powder ngokusebenzisa i-high-temperature sintering, inokuminyana okuphezulu nobulukhuni obuqinile, kodwa izinga lokushisa lokulungiselela liphezulu futhi izindleko ziyabiza, okuyenza ifanelekele izingxenye ezincane ezinembayo ezinezidingo zokusebenza eziphezulu kakhulu.
2. I-silicon carbide ecindezelwe okushisayo
Yakhelwe ngaphansi kwezinga lokushisa eliphezulu nokucindezela okukhulu, inesakhiwo esiminyene kanye nokumelana nokugqokwa okuhle kakhulu, kodwa okokusebenza kuyinkimbinkimbi futhi kunzima ukukhiqiza izingxenye ezinobukhulu obukhulu noma eziyinkimbinkimbi, ezikhawulela ububanzi bokusebenza kwayo.
3. I-Reaction sintered silicon carbide (RBSiC)
Ngokwethula izakhi ze-silicon ku-silicon carbide izinto zokusetshenziswa nokusebenzisa ukusabela kwamakhemikhali ukugcwalisa izikhala zezinto ezibonakalayo, izinga lokushisa lenqubo liphansi, umjikelezo mfushane, futhi izingxenye ezinkulu nezingajwayelekile zingenziwa ngendlela evumelana nezimo. Ukusebenza kahle kwezindleko kuvelele, okwenza kube uhlobo olusetshenziswa kakhulu lwe-silicon carbide emkhakheni wezimboni.
2, Kungani ukusabela sintered silicon carbide kuthandwa kakhulu?
Njengomkhiqizo oyinhloko webhizinisi, inqubo eyingqayizivele ye-reaction sintered silicon carbide (RBSiC) iyenza "impahla ekhethwayo" ezimbonini eziningi. Izinzuzo zayo zingafingqwa ngamagama angukhiye amathathu:
1. Iqinile futhi ihlala isikhathi eside
Inqubo ye-reaction sintering yakha "isakhiwo esihlanganisiwe" ngaphakathi kwempahla, engamelana nokushisa okuphezulu kwe-1350 ℃ futhi inokumelana okuhle kakhulu kokugqoka kanye nokumelana nokushisa okuphezulu - okungalinyazwa kalula ekugqokeni okuphezulu kanye nezimo zokushisa eziphakeme, ezifanele ikakhulukazi izimo ezisezingeni eliphezulu ezifana nezinsiza zokushisa nezibasi.
2. Yiya empini nemishini yokukhanya
Uma kuqhathaniswa nezinto zensimbi zendabuko, i-react sintered silicon carbide inomthamo ophansi kodwa inganikeza izinga elifanayo lamandla, inciphise kakhulu ukusetshenziswa kwamandla kwemishini. Isibonelo, embonini ye-photovoltaic, izingxenye ze-silicon carbide ezingasindi zingathuthukisa kakhulu ukusebenza kahle kwezithando zomlilo zekristalu eyodwa.
3. Iyavumelana nezimo futhi iguquguquka
Kungakhathaliseki ukuthi amathreyi e-semiconductor anobubanzi obungaphezu kwamamitha angu-2, imilomo eyinkimbinkimbi, izindandatho zokuvala, noma izingxenye ezimise okwezifiso ezinomumo ohlukile, ubuchwepheshe bokusabela bungalawula ngokunembile umumo nosayizi, kuxazulule inkinga yokukhiqiza "enkulu futhi enembile".
3, 'Amandla okushayela angabonakali' okuthuthukiswa kwezimboni
"Isibalo" se-action sintered silicon carbide singene ezinkambini eziningi, kusukela kumajantshi aqondisayo amelana nokuguguleka eziko zensimbi kuya kumapayipi amelana nokugqwala kuzinto zamakhemikhali. Ubukhona bayo abugcini nje ngokunweba isikhathi sokuphila kwemishini, kodwa futhi kusiza amabhizinisi ukuba afinyelele ukongiwa kwamandla kanye nokunciphisa ukusetshenziswa - isibonelo, emkhakheni weziko lezimboni, ukusetshenziswa kwefenisha ye-silicon carbide kiln kunganciphisa kakhulu ukulahlekelwa ukushisa.
Isiphetho
'Ikhono' le-carbide ceramics lidlulela ngale kwalokhu. Njengengqalabutho kubuchwepheshe be-reaction sintering, siqhubeka nokuthuthukisa inqubo ukuze sikhulise inani lalokhu okubalulekile ezindaweni ezidlulele. Uma ufuna izixazululo zezimboni ezikwazi ukumelana nokushisa, ukumelana nomthelela, futhi eziphila isikhathi eside, ungase uthande ukunaka amathuba engeziwe e-silicon carbide ceramics!
UShandong Zhongpeng ubelokhu egxile ocwaningweni nasekukhiqizweni kwe-action sintered silicon carbide iminyaka engaphezu kweshumi, ehlinzeka ngezixazululo ezenziwe ngokwezifiso zobumba kumakhasimende omhlaba.
