Njengohlobo olutsha lwezinto ezingezizo ezesinyithi, iimveliso zeseramikhi zesilicon carbide ezifakwe uxinzelelo lomoya ziye zasetyenziswa kakhulu kwi-oven, desulfurization kunye nokukhuselwa kwendalo, kushishino lweekhemikhali, kwintsimbi, kwi-aerospace nakwamanye amasimi. Nangona kunjalo, ukusetyenziswa kweemveliso zeseramikhi zesilicon carbide ezifakwe uxinzelelo lomoya kusesekwinqanaba eliqhelekileyo, kwaye kukho inani elikhulu lamasimi esicelo angakhange aphuhliswe kakhulu, kwaye ubungakanani bemarike bukhulu. Njengomvelisi weeseramikhi zesilicon carbide ezifakwe uxinzelelo lomoya, kufuneka siqhubeke nokuqinisa uphuhliso lwemarike, siphucule ngokufanelekileyo amandla emveliso, kwaye sibe kwindawo ephezulu kwicandelo elitsha lesicelo seseramikhi zesilicon carbide.
Eyona mveliso iphambili kushishino ikakhulu kukunyibilikisa i-silicon carbide enyibilikiswa ngumoya kunye nokuveliswa komgubo ocolekileyo. Icandelo elisezantsi loshishino ligubungela uluhlu olubanzi, kuquka phantse onke amashishini afuna izinto ezishushu kakhulu, ukuguguleka kunye nokugqwala.
(1) Ishishini elihamba phambili
Umgubo we-silicon carbide kunye nomgubo we-silicon metal zezona zinto ziphambili ezifunekayo kushishino. Imveliso ye-silicon carbide yaseTshayina yaqala ngeminyaka yoo-1970. Emva kweminyaka engaphezu kwama-40 yophuhliso, eli shishini lihambe indlela ende. Itekhnoloji yokunyibilikisa, izixhobo zemveliso kunye neempawu zokusetyenziswa kwamandla zifikelele kwinqanaba elifanelekileyo. Phantse i-90% ye-silicon carbide yehlabathi iveliswa eTshayina. Kwiminyaka yakutshanje, ixabiso le-silicon carbide powder alitshintshanga kangako; umgubo we-silicon metal uveliswa kakhulu eYunnan, eGuizhou, eSichuan nakwezinye iindawo ezikumzantsi-ntshona. Xa amanzi nombane zininzi ehlotyeni, ixabiso le-silicon powder yesinyithi lixabiso eliphantsi, ngelixa ebusika, ixabiso liphezulu kancinci kwaye liguquguqukayo, kodwa ngokubanzi lizinzile. Utshintsho lwamaxabiso lwezinto eziluhlaza kushishino oluphezulu lunempembelelo ethile kwimigaqo-nkqubo yamaxabiso emveliso kunye namanqanaba eendleko zamashishini kushishino.
(2) ishishini elisezantsi
Eyona nto iphambili kushishino yimveliso ye-silicon carbide ceramic. Iimveliso ze-silicon carbide ceramic azikho nje kuphela ezahlukeneyo, kodwa zikwasebenza kakuhle. Zisetyenziswa kakhulu kulwakhiwo, ii-ceramics zococeko, ii-ceramics zemihla ngemihla, izixhobo zemagnethi, ii-glass-ceramics, ii-ovens zoshishino, iimoto, iipompo, ii-boilers, izitishi zamandla, ukhuseleko lokusingqongileyo, ukwenza iphepha, i-petroleum, i-metallurgy, ishishini leekhemikhali, oomatshini, i-aerospace kunye nezinye iindawo. Ngenxa yokusebenza okuphezulu kweemveliso ze-silicon carbide ceramic eziye zaqatshelwa ngamashishini amaninzi, uluhlu lwemveliso ye-silicon carbide ceramic luya kuba banzi ngakumbi nangakumbi. Uphuhliso olusempilweni, oluzinzileyo nolukhawulezayo lweshishini elisezantsi luya kubonelela ngendawo ebanzi yemarike kushishino kwaye lukhuthaze uphuhliso olucwangcisiweyo lweshishini lonke.
Ngokusetyenziswa ngokubanzi kweemveliso ze-silicon carbide ceramic ezixineneyo zoxinzelelo lomoya, imfuno yemarike nayo iyanda, itsala inxalenye enkulu yenkunzi kwicandelo lokwenziwa kwe-silicon carbide ceramic. Kwelinye icala, ubungakanani boshishino lwe-silicon carbide buyaqhubeka nokukhula, kwaye imveliso yokuqala yengingqi isasazeka kancinci kuzo zonke iindawo zelizwe. Kwixesha elifutshane leminyaka elishumi, ishishini le-silicon carbide liphuhlile ngokukhawuleza. Kwelinye icala, ngelixa ubungakanani boshishino buqhubeka nokukhula, likwajongene nokhuphiswano olubi. Ngenxa yokungena okuphantsi koshishino, inani lamashishini emveliso likhulu, ubungakanani bamashishini bahlukile, kwaye umgangatho wemveliso awulingani.
Amanye amashishini amakhulu agxila ekuphuculeni ubuchwepheshe kunye nophando kunye nophuhliso lwemveliso entsha; Ubungakanani buyaqhubeka nokukhula, kwaye ukubonakala kunye nempembelelo yenkampani kuyanda imihla ngemihla. Kwangaxeshanye, abavelisi abancinci abaninzi banokuxhomekeka kuphela kwisicwangciso esingabizi kakhulu ukuze bafumane ii-odolo, nto leyo ekhokelela kukhuphiswano olubi kushishino. Ukhuphiswano kushishino lunamandla, kwaye ishishini liya kubonisa umkhwa wokuqhekeka kwamashishini.
