Uhlolojikelele lwe-Alumina ceramic shaft

Amashafu e-alumina ceramic akhiwa ikakhulukazi i-Al₂O₃. I-alumina ceramic shaft iwuhlobo lwezingxenye ze-alumina zobumba ezinobulukhuni obuphakeme kakhulu, ukumelana nokugqokwa okuhle, futhi ezingasebenza ngokuzinza ezindaweni ezingqubuzana. Zisetshenziswa kabanzi emishinini yezimboni, imishini ye-elekthronikhi, i-aerospace kanye neminye imikhakha, ihlinzeka ngokusekelwa okuqinile kokusebenza okuzinzile kwemishini.

Izici ze-Alumina ceramic shaft

I-alumina shaft ye-ceramic shaft ye-ceramic eyenziwe nge-alumina njengento eyinhloko eluhlaza, enezici eziningi ezinhle kakhulu. Ukuqina kweshaft ye-alumina ceramic kuphakeme kakhulu, kufinyelela ezingeni 9, eliphindwe izikhathi eziningana kunobulukhuni bezinto ezijwayelekile zensimbi. Ingakwazi ukumelana nokuklwebheka ezintweni zangaphandle futhi yandise impilo yayo yenkonzo. Ngesikhathi esifanayo, i-alumina ceramic shaft inokumelana okuhle kakhulu kokugqoka, okunganciphisa ukuguga ngesikhathi sokusebenza ngesivinini esikhulu futhi kuthuthukise ukusebenza kahle kwemishini. Ngaphezu kwalokho, i-alumina ceramic shaft nayo inokumelana nokugqwala okuhle kakhulu futhi ingasetshenziswa ezindaweni ezinokhahlo njenge-asidi ne-alkali ngaphandle kokugqwala noma ukubola. Ukusebenza kwayo kwe-insulation nakho kuhle kakhulu, futhi kungasetshenziswa kabanzi ezintweni zikagesi nezikagesi ukugwema izingozi zokuphepha njengokuvuza kwamanje nomlilo.

Mayelana nezakhiwo ezibonakalayo, i-alumina ceramic shaft ine-density ephansi futhi ilula kunensimbi. Iphinde ibe nokumelana okuhle kwezinga lokushisa eliphezulu futhi ingasebenza ngokuzinzile endaweni efinyelela ku-1650 ° C, futhi izinga lokushisa lokusebenza lingafinyelela ku-1650 ° C ngaphandle komthwalo wemishini. I-conductivity yayo yokushisa i-20 kuya ku-32W / MK, i-coefficient yokwandisa ukushisa okushisayo i-7 ~ 8 × 10⁻⁶ / ° C, futhi ukumelana nokushaqeka okushisayo kungafinyelela ku-200 ° C (kufakwe emanzini), okungakwazi ukuzivumelanisa nezimo ezinokushintsha kwezinga lokushisa okukhulu kakhulu. Ngesikhathi esifanayo, i-alumina ceramic shaft ine-conductivity enhle yokushisa, ingasusa ngokushesha ukushisa, futhi igcine ukusebenza okuzinzile kwemishini.

Mayelana nezakhiwo zamakhemikhali, ama-alumina ceramic shafts akhombisa ukuzinza okuhle kwamakhemikhali, ukumelana ne-asidi ne-alkali, nokumelana nokugqwala. Angakwazi ukugcina ukusebenza okuzinzile ngisho nasezindaweni zamakhemikhali ezinonya futhi afaneleka ngokukhethekile imikhumbi yokusabela, amapayipi, kanye nezingxenye zokuzivikela embonini yamakhemikhali. Ngaphezu kwalokho, ama-alumina ceramic shafts awasebenzi ngokwebhayoloji, awanangozi emzimbeni womuntu, futhi anokuhambisana okuhle kokudla.

Mayelana nezakhiwo zemishini, amashafu e-alumina ceramic anamandla aphakathi ukuya kwaphezulu kakhulu, anamandla acindezelayo angu-2000 kuya ku-4000 MPa, amandla aguquguqukayo angu-280 kuya ku-350 MPa, ukuqina kokuphuka kwe-3~4 MPa·m¹/² noma 4.5 MPa·m¹. 99.5 kuya ku-320 GPA. Azikhubazeki kalula uma ziphoqelelwa, okusiza ekwandiseni isivinini sokusebenza kanye nokuzuza ukunemba okuphezulu. Ngaphezu kwalokho, ama-alumina e-ceramic shafts nawo anobunzima obuphezulu, enobulukhuni be-370 GPa ye-13.7% ye-alumina kanye nokuqina kwe-95 GPa ye-15.2% ye-alumina kanye ne-99% ye-alumina.

5 FAQs of Alumina ceramic shaft

Q1:Kungani kunzima ukucubungula ama-alumina ceramic shafts?

 Ubunzima bokucubungula i-alumina ceramic shafts ikakhulukazi ngenxa yobulukhuni bayo obukhulu, ukuqina kwayo kanye ne-anisotropy. Ukuqina kwayo kungokwesibili ngemuva kwedayimane, futhi kunzima ukusika ngamathuluzi endabuko futhi kulula ukugqoka; i-brittle futhi kulula ukudilika, ukuqhekeka noma ngisho nokuphuka ngesikhathi sokucutshungulwa, ikakhulukazi ezakhiweni ezinezindonga ezincane, eziyinkimbinkimbi noma ukucubungula imbobo encane; ukuqondiswa kokukhula okusanhlamvu ngesikhathi sokugcoba kuholela ku-anisotropy yezinto ezibonakalayo zemishini, okulula ukubangela ukucindezeleka okungalingani, futhi ama-microcracks angaphakathi, ama-pores kanye nezinye iziphambeko kuzonciphisa amandla wezinto ezibonakalayo, okuholela ekunciphiseni kokucubungula isivuno.

Q2:Ungayixazulula kanjani inkinga ye-brittleness ekucutshungulweni kwe-alumina ceramic shafts?

Sebenzisa amathuluzi edayimane noma amasondo okugaya e-CBN okugaya nokusika; sebenzisa ukucubungula okusizwa nge-ultrasonic ukunciphisa amandla okusika nokunciphisa ukuwa komkhawulo; lungiselela amapharamitha wokucubungula, njengokunciphisa isivinini sokuphakelayo nokukhulisa isivinini sokuzungeza ukuze kuncishiswe ukugxilwa kwengcindezi.

Q3: Kungani izindleko zokucubungula ze-alumina ceramic shafts ziphezulu kangaka?

 Ngakolunye uhlangothi, ukucutshungulwa kwe-alumina ceramic shafts kunzima futhi kudinga amathuluzi abizayo njengamathuluzi edayimane noma amasondo okugaya e-CBN, futhi la mathuluzi aguga ngokushesha; ngakolunye uhlangothi, okokusebenza okudingekayo ukuze kucutshungulwe ngokunembayo, njengama-grinder e-axis amahlanu nama-lasers asheshayo, kunokutshalwa kwezimali okuphezulu nokugcinwa okuyinkimbinkimbi, okuholela ezindlekweni zokucubungula eziphezulu.

Q4: Uyini umehluko phakathi kwe-alumina ceramic shafts yokuhlanza okuhlukile?

99% amashafu e-alumina ceramic ngokuvamile asetshenziselwa amashafu amancane aphakathi, ikakhulukazi akhonza amakhasimende amaphakathi, ahlanzekile nokusebenza okuphezulu; Ama-95% amashafu e-alumina ceramic asetshenziswa kakhulu kumashafu amakhulu amakhulu, ikakhulukazi asebenzela amakhasimende aphakathi nendawo nasezingeni eliphansi, ngezindleko eziphansi uma kuqhathaniswa.

Q5: Ungawavimba kanjani amabala angaphezulu ku-alumina ceramic shafts?

Ngesikhathi sokubunjwa kokucindezelwa, khetha izinto ezingavuthiwe zekhwalithi ephezulu ezinokuqukethwe kwensimbi ephansi futhi wenze ukwahlukanisa kazibuthe ukuze ususe insimbi uma kudingeka; qaphela inqubo yokugaya, bheka ukuthi izitini ze-lining zomshini webhola ziyawa futhi uzilungise ngesikhathi; ngesikhathi se-granulation, engeza ukuhlukaniswa kazibuthe ukuze ukhiphe insimbi lapho uhambisa udaka, futhi usebenzise iziko lomoya oshisayo nezihlungi zomoya oshisayo ukuvimbela ukugqwala ekungeneni kwezinto ohlelweni lomoya oshisayo. Ukuhlukaniswa kwamagnetic kwenziwa ku-powder granulated ngaphambi kokuba umkhiqizo wokugcina uhlanganiswe; wonke amapayipi okudlulisa kufanele afakwe i-polyurethane ngangokunokwenzeka.
