1. Ithonya lempuphu yezinto ezingavuthiwe
Izinto zokusetshenziswa ezibaluleke kakhulu ze-ceramics ezingagugi ze-alumina yi-high-purity alumina powder. Ukusebenza kwayo kanye nokuqukethwe kwayo kunethonya elikhulu kwi-ceramics ezingagugi ze-alumina. I-ceramic powder izofaka ukungcola ngokungenakugwenywa ngesikhathi senqubo yokulungiselela, futhi ukungcola kwezinto eziphilayo kuzoshiswa ngesikhathi senqubo yokusila, kwakha ama-pores angajwayelekile ngesikhathi senqubo yokuminyana; ukungcola okungaphili kuzosabela ne-ceramic powder ekushiseni okuphezulu noma ku-matrix Ukwakheka kwama-microcracks. Lokhu kungcola kunomthelela omkhulu ekuminyaneni kwe-alumina ceramics. Usayizi wezinhlayiya ze-powder yezinto zokusetshenziswa nazo unethonya elikhulu ekusebenzeni komkhiqizo. Kuphela uma izinto zokusetshenziswa sezilungile ngokwanele, umkhiqizo wokugcina osikiwe ungakha isakhiwo se-microcrystalline, okwenza ube nokumelana okuhle kokuguguleka. Ngakho-ke, i-alumina powders ehlanzekile kakhulu, enezinhlamvu ezincane iyimfuneko ebalulekile yokulungiselela i-alumina ceramics engagugi.
2. Ithonya lendlela yokubumba
Umkhuba wokukhiqiza kanye nenani elikhulu lezifundo kubonise ukuthi izitsha ze-alumina ezinezimbobo ezincane, ezinobukhulu obuphezulu zinezakhiwo ezinhle kakhulu zesakhiwo. Ubukhulu obuphezulu busho ukuthi izinhlamvu zekristalu emzimbeni we-ceramic zihlelwe eduze, futhi akulula ukuthuthukisa indawo yokuphambuka ebhubhisayo lapho zibhekene nemithwalo yangaphandle yemvelo noma izinto ezibolayo.
Ukuze uthole indlela yokubumba umzimba we-ceramic enobuningi obukhulu kubalulekile. Izitsha zobumba ezingagugi ze-Alumina ngokuvamile zingakhiwa ngokucindezela okomile, ukucindezela kwe-isostatic, ukuphonswa kwe-hot die kanye nezinye izindlela. Izindlela ezahlukene zokugcoba zinezici ezahlukene futhi zinemiphumela ehlukile ezimpahleni zokugcoba kanye nesakhiwo esincane se-alumina ceramics.
Imikhiqizo enezimo ezahlukahlukene ngokuvamile icutshungulwa nge-grouting noma i-hot-press casting, kanti imikhiqizo enezimo ezilula yakhiwa ngokucindezela okomile.
3. Umphumela wokucwenga
Ukusinta kuyisigaba esibalulekile ekulungiseleleni izinto zobumba, futhi isimo sokusinta sinethonya elikhulu ekulungiseleleni izinto zobumba. Izinga lokushisa eliphakeme kakhulu lokushisa noma isikhathi eside kakhulu sokuphatha kuzokhuthaza ukukhula kwamakristalu, okwenza izinto zokusetshenziswa ezincane zikhule zibe izinhlamvu eziqinile ekushiseni okuphezulu, futhi okuqukethwe kwesigaba soketshezi kuzokwanda. Lokhu akugcini nje ngokunciphisa amandla, kodwa futhi kunciphisa ukumelana nokuguguleka. Vele, uma izinga lokushisa liphansi kakhulu, umzimba osintayo ngeke ube mkhulu, futhi ukumelana nokuguguleka komkhiqizo ngeke kube kuhle.
Ukushisa isithando sikagesi okuhle kakhulu kungalawula ngokunembile inqubo yokushisa, yokubamba kanye nokupholisa, edlala indima ebalulekile ekuthuthukiseni ukumelana nokuguguleka kwezinto zobumba, kodwa izindleko zokushisa kanye nokusetshenziswa kwezinto ezingaphili zehhavini likagesi kuphakeme kunezimayini zamalahle.
4. Isisheshisi sokuvutha
Ukushisa okufanele kusiza ekunciphiseni izinga lokushisa ngesikhathi sokushisa, kuthuthukise isakhiwo esincane sezinto zobumba, futhi kuthuthukise izakhiwo zemishini, ngaleyo ndlela kuthuthukise ngempumelelo ukumelana nokuguguleka kwezinto zobumba ezingagugi ze-alumina.
Umkhiqizi we-CHEMSHUN CERAMIC unaka kakhuluamathayili okugqoka e-alumina ceramicikhwalithi yokukhiqiza. Siyakwamukela ekubuzeni.
