Kwicandelo lokubumba ngesinyithi, umgangatho wesanti yokubumba uchaphazela ngokuthe ngqo ukuchaneka, umgangatho kunye nokusebenza kakuhle kwemveliso yokubumba. Njengesixhobo esichasayo se-aluminosilicate esisebenza kakuhle,isanti ye-mullite yokuphosaIthandwa kakhulu lishishini lokuthunga elikumgangatho ophezulu ngenxa yokumelana kwayo nobushushu obuphezulu, uzinzo oluphezulu kunye nokungasebenzi kakuhle kweekhemikhali. Eli nqaku ligxile ekwaziseni usetyenziso kunye neenzuzo zalo eziphambili, likunceda uqonde ixabiso lesanti ye-mullite yokuthunga ekwenzeni ngcono iinkqubo kunye nokunciphisa iindleko.
Izicelo eziPhambili
1. Ukusasazwa koTyalo-mali oluchanekileyo:Yinto ephambili yokwenza iqokobhe kwi-lost-wax casting, esetyenziswa kwi-backlayer nakwi-reinforcement layer. Ixutywe ne-silica sol kunye ne-mullite powder, inokwenza iqokobhe eliqinileyo neliqinileyo, elinokumelana nokuguquguquka nokuqhekeka ngexesha lokurosa nokuthulula, ukuqinisekisa ukuchaneka okuphezulu kwezinto ezifana nee-aero-injini turbine blades kunye neebhloko zeenjini zemoto.
2. Ukuphosa Okunzima:Njengoko inamandla okuchasana ne-≥1750℃, inokumelana namaqondo obushushu aphezulu angaphezu kwe-1600℃ kwaye imelane nokukhukuliseka kwesinyithi esinyibilikisiweyo kunye ne-slag. Njengesanti yokubumba okanye isanti engundoqo yezinto ezinkulu zentsimbi kunye nezinto zesinyithi, inokugcina ukuthembeka kwesikhunta, iphephe iziphene ezifana nokufakwa kwesanti, kwaye inciphise iindleko zomsebenzi zokucoca emva kokugalela.
3. Ukuphoswa kweAlloy ekhethekileyo:Umxholo wayo ophantsi wentsimbi kunye ne-titanium kunye nokuzinza okuhle kweekhemikhali kunokuthintela ukusabela ngee-alloys ezikhethekileyo ezinyibilikisiweyo (ezifana nentsimbi engagqwaliyo kunye nee-alloys ezishushu kakhulu), kuthintele ungcoliseko kunye nokufakwa kwe-oxide, kwaye kuqinisekiswe ubunyulu kunye nokugqitywa komphezulu wee-castings.
Iingenelo ezingundoqo
Isanti ye-Mullite yokuphosa isombulula iingongoma zesanti yokubumba yendabuko: ukumelana nobushushu obuphezulu kakhulu (≥1750℃) kuqinisekisa uzinzo lwesikhunta; i-coefficient yokwandiswa kobushushu obuphantsi igcina ukuchaneka kobukhulu; ukungangeni kweekhemikhali kukhusela umgangatho wokuphosa; ukungena komoya okuhle kunciphisa iziphene ezifana nemingxunya yomoya. Inokuphucula izinga lokufaneleka kokuphosa kwaye inciphise iindleko emva kokucocwa, okwenza kube lukhetho olufanelekileyo kwiimeko zokuphosa ezifunwa kakhulu.
Iinkcukacha zeMesh eziqhelekileyo
Isanti yethu ye-mullite yokusika inoluhlu olupheleleyo lwee-mesh specifications, ezigubungela iimfuno zeemeko ezahlukeneyo zokusika. Ubungakanani be-mesh eqhelekileyo buquka i-8-16 mesh, i-16-30 mesh, i-30-60 mesh, i-60-80 mesh kunye ne-80-120 mesh. Sikwabonelela ngeenkcukacha ze-mullite powder ezifana ne-200 mesh kunye ne-300 mesh, ezinokuhambelana ngqo neemfuno ezahlukeneyo zenkqubo yokusika ngokuchanekileyo utyalo-mali, ukusika okunzima, ukusika okukhethekileyo kwe-alloy, njl. Phakathi kwazo, i-30-60 mesh idla ngokusetyenziselwa ukuvelisa i-slurry exhasayo, kwaye i-16-30 mesh ifanelekile ukusetyenziswa komaleko wokuqinisa, ukuhlangabezana neemfuno ezithile zeenkqubo ezahlukeneyo.
Amandla eNkonzo yokwenza ngokwezifiso
Sithembele kwimigca yemveliso yanamhlanje ekrelekrele kunye neqela leengcali ze-R&D, sinamandla okwenza ngokwezifiso. Singenza iimveliso zesanti ye-mullite ngokwezifiso ezinobukhulu obukhethekileyo be-mesh (ezinokwenziwa ngokwezifiso ukusuka kwi-mesh ezili-10 ukuya kwi-mesh ezingama-325), ubumsulwa kunye nokuhlelwa kwee-particle ngokweenkqubo ezithile zokuphosa zabathengi, izixhobo zokuphosa kunye neemfuno zokusebenza. Ukusuka ekukhetheni izinto eziluhlaza, ukulungiswa kobungakanani be-particle ukuya ekuhlolweni komgangatho, sinikezela ngenkonzo epheleleyo yenkqubo yomntu ngamnye, sizivumelanisa ngokulula neemfuno ezenzelwe wena zamashishini ahlukeneyo afana neenqwelo moya, iimoto kunye ne-metallurgy. Kwangaxeshanye, siqinisekisa uzinzo lokunikezelwa kwebhetshi kunye nokuhambelana komgangatho, sinceda abathengi baphucule iinkqubo zemveliso kwaye baphucule ukukhuphisana kwemveliso.
