Kusukela kumapayipi okuthutha kuya ezimotweni ezintsha zamandla, kusukela kumahhavini okushisa okuphezulu kuya kumasathelayithi ezindiza, into eyaziwa ngokuthi “idayimane lezimboni” ibhala kabusha buthule imingcele yokukhiqiza yesimanje.Izitsha zobumba ze-silicon carbide, into eqinile kakhulu enobulukhuni obulandela idayimane yemvelo kuphela, ibangela inguquko ethule emikhakheni ehlukahlukene efana nemboni yesimanje, ama-semiconductor, izindiza, kanye namandla amasha ngenxa yokumelana kwayo nokushisa okuphezulu, ukumelana nemisebe enamandla, kanye nokuqhuba kahle kokushisa.
Lapho 'amathambo aqinile' ehlangana nokukhiqizwa okunembile
Uma izinto zobumba zendabuko ziyi-porcelain eluhlaza okwesibhakabhaka nomhlophe kwezobuciko kanye nemisebenzi yezandla, khona-ke izinto zobumba ze-silicon carbide zifana kakhulu namawashi aseSwitzerland amathuluzi okunemba. Ubulukhuni bawo buphindwe kathathu kuya kahlanu kunobobumba obujwayelekile, futhi lobu bulukhuni obufana namadayimane emvelo benza inqubo yokugaya ifane nokubaza emapuletini ensimbi - amathuluzi okusika avamile ayaguga ngesivinini esimangalisayo ngesikhathi sokusika. Okuyinkimbinkimbi nakakhulu ukuthi uhlobo "oluqinile" lwe-silicon carbide luyenza ithambekele ekuqhekekeni konqenqemeni ngisho nangephutha elincane ngesikhathi sokucutshungulwa, ikakhulukazi kwezinye izingxenye ezinezindonga ezincane ezidinga ukuqapha okufanayo njengobuciko bekristalu.
Kodwa isidingo semboni yanamuhla siholela ekuthuthukisweni kwezobuchwepheshe. Onjiniyela bathole ukuthi isihluthulelo sokuxazulula le nkinga sisekuhlanganisweni kokuqina nokuguquguquka: ukugcina izakhiwo zangaphakathi zezinto ngenkathi kusetshenziswa ukulawula okunembile ngesikhathi sokucubungula. Njengabapheki abaphezulu abanekhono lokulawula ukushisa, amasu okucubungula esimanje anciphisa kancane kancane le nto eqinile ngokulawula okunembile izinga lokushisa, ingcindezi, kanye nemvamisa yokudlidliza.
Izihluthulelo ezintathu zokuvula amadayimane ezimboni
1. Ukucindezela okushisayo kokubumba
Lena enye yezindlela ezivame kakhulu zokucubungula i-silicon carbide ceramics. Le ndlela ibeka i-silicon carbide powder noma i-mixed powder ku-hot pressing mold bese iyicubungula ibe yisimo ngaphansi kokushisa okuphezulu kanye nengcindezi. Isebenza kahle kakhulu ekukhiqizeni nasekubumbeni, futhi ifaneleka ekukhiqizeni imikhiqizo emikhulu ye-silicon carbide ceramic efana namathuluzi okusika, amapuleti e-aluminium adonswayo ashisayo, njll.
2. Ukubumba i-grouting
Lena indlela yokwakha eshibhile futhi esheshayo yemikhiqizo ye-silicon carbide ceramic. Le ndlela ixuba i-silicon carbide powder nezinye izithasiselo, izifake emanzini ukuze zenze i-slurry, bese iyifaka esikhumbeni sokubumba. Bese, iyacutshungulwa futhi yenziwe ngokomiswa kanye nokushiswa kwezinga lokushisa eliphezulu, ngomjikelezo omfushane wokucubungula kanye nezindleko eziphansi. Ifanele ukulungiselela izingxenye ezinamandla aphezulu, ezinobukhulu obuphezulu kanye nezingxenye ezithwala umthwalo.
3. I-powder metallurgy
I-powder metallurgy iyindlela yokuxuba nokubumba i-silicon carbide powder ngesilinganiso esithile, bese uyithulula ekushiseni okuphezulu kanye nokucindezela okuphezulu. Le ndlela inenqubo elula yokukhiqiza, izimo zomkhiqizo ezahlukahlukene, kanye nokunemba okuphezulu kokucubungula, okwenza ifaneleke ukukhiqiza imikhiqizo ye-ceramic enembile kakhulu, enamandla aphezulu, futhi engagugi.
Kusukela kumasampula elebhu kuya ekukhiqizweni okukhulu emgqeni wokukhiqiza, intuthuko ekucutshungulweni kwe-silicon carbide ceramics iqinisekisa iqiniso: akukho nto engenakucutshungulwa, ubuchwepheshe kuphela obungakaqedwa. Ngokuvuthwa kobuchwepheshe obusha njengokucubungula nge-laser kanye nokushiswa kwe-microwave, le nto eyayike yaba nzima kakhulu iyavuselela ezimbonini ezihlakaniphile, ifaka amandla aqinile “ekukhiqizeni okuhlakaniphile kwaseShayina”.
Olwandle olukhulu lokuhlola isikhala kanye negagasi eliluhlaza lamandla ahlanzekile, izitsha zobumba ze-silicon carbide zibhala inganekwane yezimboni yalesi sikhathi ngobuhle bazo obuyingqayizivele bezinto ezibonakalayo. Lokhu kuphikisana phakathi kobulukhuni nobuhlakani kungaba yisibonelo saphakade sesintu esidlula imingcele yezobuchwepheshe.
