Emkhakheni wokukhiqizwa kwezimboni, ukukhetha izinto ezifanele ze-ceramic kufana nokuthola ozakwethu abanokwethenjelwa - kudinga ukumelana nokuhlolwa kwesikhathi, ukumelana nezimo ezibucayi, nokuqhubeka nokwengeza inani ekusebenzeni kahle kokukhiqiza. Ungakwenza kanjani ukukhetha okuhlakaniphile lapho ubhekene nenqwaba ekhazimulayo yemikhiqizo ye-ceramic yezimboni? Lesi sihloko sizodalula izici ezibalulekile zokukhethwa kwezinto ezisebenzayo futhi sigxile ekuhlaziyeni izinzuzo eziyingqayizivelei-silicon carbide ceramics, eyaziwa ngokuthi "izikhali zezimboni".
1, Imithetho Emithathu Yegolide Yokukhetha I-Industrial Ceramics
1. Idigri yokufanisa ukusebenza: Okokuqala, kuyadingeka ukucacisa izidingo ezibalulekile zesimo sokusetshenziswa. Ingabe imvelo yezinga lokushisa eliphakeme kakhulu? Indawo edlayo eqinile? Noma i-high-frequency mechanical friction? Njengokukhetha izinto zokuqwala izintaba ukuze zihlukanise phakathi kweqhwa nogwadule, izimo zokusebenza ezihlukene zidinga izinto zobumba ezinezici ezihambisanayo.
2. Umjikelezo wempilo yesevisi: Inani lezitsha zobumba zekhwalithi ephezulu libonakala ekusetshenzisweni kwesikhathi eside. Akufanele sinake kuphela izindleko zokuqala zokuthengwa kwempahla, kodwa futhi sibale izindleko ezicashile ezibangelwa ukunakekela kanye nemvamisa yokushintshanisa. I-ceramics yezimboni yekhwalithi ephezulu kufanele ithembeke njengokuthi "izingxenye zamahhala zokunakekela".
3. Amandla okusekela ngobuchwepheshe: Abahlinzeki abahle kakhulu abakwazi ukuhlinzeka ngemikhiqizo evamile kuphela, kodwa futhi bathuthukise amafomula nezakhiwo zokuklama ngokusekelwe ezimweni ezithile zokusebenza, okuvamise ukunquma ukusebenza kokugcina kwezinto ezisetshenziswayo.
2, Izinzuzo ezine zokusebenza ezinkulu ze-silicon carbide ceramics
Njengenkanyezi yezinto zobumba zesimanje zezimboni, izitsha zobumba ze-silicon carbide seziba yinketho ekhethwayo emabhizinisini amaningi. Inhlanganisela yayo eyingqayizivele yokusebenza ingabizwa ngokuthi "iqhawe eline-hexagonal" lezinto zezimboni:
1. Izikhali zempi ezihlala isikhathi eside kakhulu: Isakhiwo sekristalu sisinikeza ubulukhuni okwesibili kuya kwedayimane, esinganweba ngempumelelo impilo yesevisi yezisetshenziswa ezimeni ezifana nezinhlelo zokudlulisa ezigcizelelwe ngokuqhubekayo namabheringi anembayo.
2. Isivikelo sekhemikhali: Sinokumelana okuhle kakhulu nama-asidi aqinile, izinsimbi ezincibilikisiwe, njll., futhi sifaneleka ngokukhethekile ezindaweni ezigqwalayo njengemikhumbi yokusabela kwamakhemikhali kanye nezinhlelo ze-industrial desulfurization, ukugwema ukungcola okuphakathi okubangelwa ukulahlekelwa izinto ezibonakalayo.
3. I-Thermal Stability Guardian: Ingakwazi ukugcina ukuqina kwesakhiwo ngisho nakumazinga okushisa aphezulu angu-1350 ℃, nge-coefficient yokunweba okushisayo engu-1/4 kuphela wensimbi, okuyenza ibe ukukhetha okuhle kwamakhilni anezinga lokushisa eliphezulu kanye nezinhlelo zokuvikela ukufudumala kwemikhumbi-mkhathi.
4. Isazi esisindo esingasindi: Ngokuminyana kuphela ingxenye eyodwa kwezintathu yaleso yensimbi, inganikeza amandla afanayo noma aphakeme ngisho nangaphezulu, futhi inezinzuzo ezisobala emishinini yokuzenzakalela kanye nezinkambu zamandla ezintsha ezidinga ukuncishiswa kwesisindo nokuthuthukiswa kokusebenza kahle.
3, Iziphakamiso zokukhetha izinto ezithuthukisiwe
Ngokungeziwe kumapharamitha ayisisekelo, kunconywa ukuthi ugxile emininingwaneni yenqubo efana nokufana kwesakhiwo se-microstructure kanye nokushelela kwendawo. Lezi 'zimfanelo ezingabonakali' zivame ukunquma ukusebenza kwezinto ezimweni ezibucayi.
Ukukhetha i-ceramics yezimboni empeleni ukukhetha "umqaphi" womugqa wokukhiqiza. I-silicon carbide ceramics, nenhlanganisela yazo eyingqayizivele yezakhiwo, ichaza kabusha ukuqonda kokuthembeka ekukhiqizeni izimboni. Lapho ubhekene nezinselele zokusebenza eziyinkimbinkimbi, vumela lo mdlali osebenza ngezindlela eziningi embonini yezinto zokwakha akwakhele umugqa wokuzivikela oqinile.
Sibambe iqhaza ngokujulile emkhakheni we-silicon carbide ceramics iminyaka engaphezu kweshumi, sigxile ekuhlinzekeni izixazululo zempahla ezenziwe ngokwezifiso zamakhasimende. VakashelaShandong Zhongpengukuze uthole idatha elinganisiwe eyengeziwe kuzimo zohlelo lokusebenza, noma uxhumane nethimba lethu lonjiniyela ukuze wenze ngendlela oyifisayo izixazululo zokukhetha izinto eziqondene nawe.
