Mullite Sand
Ulwazi lweMveliso
Isanti yeMulliteyi-aluminium silicate refractory material, esetyenziswa ngokubanzi kwinkqubo yokuphosa echanekileyo yensimbi engenasici. I-refractoriness imalunga ne-1750 degrees. Ukuphakama kwesiqulatho se-aluminiyam kwisanti ye-mullite, isezantsi isiqulatho sentsimbi, kunye nothuli oluncinci, ungcono umgangatho wemveliso yesanti ye-mullite. Isanti yeMullite yenziwa ngokufakwa kobushushu obuphezulu be-kaolin.
Iimbonakalo:
1. Indawo ephezulu yokunyibilika, ngokubanzi phakathi kwe-1750 kunye ne-1860°C.
2. Uzinzo oluhle lobushushu obuphezulu.
3. I-coefficient yokwandisa i-thermal ephantsi.
4. Ukuzinza kweekhemikhali eziphezulu.
5. Ukusabalalisa ubungakanani be-particle enengqiqo kuvumela ukukhetha kunye nokulungiswa ngokusekelwe kwiinkqubo ezahlukeneyo zokuphosa kunye neemfuno zokuphosa.

Usetyenziso
Undoqo wokwenziwa kweqokobhe lokungunda (inkqubo yokwaleka ipateni yewax enemaleko amaninzi ezinto eziphikisayo ukwenza iqokobhe langaphandle. Emva kokuba ipateni yewax inyibilika, kwenziwa umngxuma wokugalela isinyithi esinyibilikisiweyo). Isanti ye-Mullite isetyenziswa ngokuyintloko njenge-refractory aggregate kwiqokobhe lokungunda kwaye isetyenziswa kumaleko ahlukeneyo eqokobhe, ngokukodwa ngolu hlobo lulandelayo:
1. I-Surface Shell (Imisela ngokuthe ngqo uMgangatho woMphezulu wokuSasa)
Umsebenzi:Umaleko womphezulu unxibelelana ngokuthe ngqo kunye nokuphosa kwaye kufuneka uqinisekise ukugqitywa komphezulu ogudileyo (ukuphepha uburhabaxa kunye nemingxuma) ngelixa umelana nempembelelo yokuqala yesinyithi esinyibilikisiweyo.
2. I-Back Shell (Ibonelela ngamandla onke kunye nokuphefumla)
Umsebenzi:Iqokobhe elingasemva sisakhiwo esinamaleko amaninzi ngaphandle komgangatho ongaphezulu. Ixhasa amandla onke egobolondo lokubumba (ukuthintela i-deformation okanye ukuwa ngexesha lokuthululela) ngelixa uqinisekisa ukuphefumla (ukukhupha iigesi kwi-cavity kunye nokukhusela i-porosity kwi-casting).
3. Izicelo eziKhethekileyo zokuCasa eziBande kakhulu
Ubushushu obuphezulu be-alloy castings:njengeentsimbi ze-injini ye-injini yenqwelomoya (iqondo lobushushu eligalela i-1500-1600°C), lifuna iqokobhe lokungunda likwazi ukumelana namaqondo obushushu agqithisileyo. Ukuqina okuphezulu kwesanti ye-Mullite kunokuthatha indawo yesanti ye-zircon ebiza kakhulu (indawo yokunyibilika engama-2550°C, kodwa iyabiza), ikhawulelana neemfuno zokuxhathisa ubushushu obuphezulu ngelixa inciphisa iindleko.
Ukwenziwa kweentsimbi ezisebenzayo:ezifana ne-aluminium alloys kunye ne-magnesium alloys (esebenza kakhulu kwaye isabela ngokulula kunye ne-SiO₂ kwisanti ye-quartz ukuze yenze i-inclusions), i-mullite ye-santi ye-chemical stability inokunciphisa ukusebenza kwakhona kunye nokuthintela ukubunjwa "kwe-oxidation inclusions" kwi-casting.
Ngokwenza izinto ezinkulu ezichanekileyo:ezifana nezindlu zebhokisi ye-injini yomoya (enobunzima beetoni ezininzi), iqokobhe lokungunda lifuna amandla aphezulu olwakhiwo. I-backing layer eyenziwe yisanti ye-mullite kunye ne-binder iphezulu-amandla, ukunciphisa umngcipheko wokwandiswa kwesikhunta kunye nokuwa.
4. Ukudityaniswa nezinye iziXhobo zeRefractory
Kwimveliso yokwenyani, isanti ye-mullite ihlala isetyenziswa ngokudityaniswa nezinye izinto ukwenza ngcono ukusebenza kweqokobhe lokungunda:
Ukudibanisa nesanti ye-zircon:Isanti ye-zircon isetyenziswa njengomaleko womphezulu (ukuqinisekisa ukugqitywa komphezulu ophezulu) kunye nesanti ye-mullite njengoluhlu oluxhasayo (ukunciphisa iindleko). Oku kulungelelaniso olunemfuno eziphezulu kakhulu zomphezulu, njengendawo ye-aerospace.
Idityaniswe nesanti yequartz:Ukwenziwa kwesanti ezineemfuno zobushushu obusezantsi (ezifana nengxubevange yobhedu, indawo yokunyibilika eyi-1083℃), inokutshintsha ngokuyinxenye isanti yequartz kwaye isebenzise ukwandiswa okuphantsi kwesanti ye-mullite ukunciphisa iintanda zeqokobhe.
