Emkhakheni wokubumba ngensimbi, ikhwalithi yesihlabathi sokubumba ithinta ngqo ukunemba, ikhwalithi kanye nokusebenza kahle kokubumba. Njengento ephikisayo ye-aluminosilicate esebenza kahle kakhulu,isihlabathi se-mullite sokuphonswaithandwa kakhulu yimboni yokukhipha izinto ezisezingeni eliphezulu ngenxa yokumelana kwayo nokushisa okuphezulu, ukuzinza kobukhulu kanye nokungangeni kwamakhemikhali. Lesi sihloko sigxile ekwethuleni izinhlelo zokusebenza nezinzuzo zaso eziyinhloko, sikusiza ukuthi uqonde inani lesihlabathi se-mullite sokukhipha izinto ekwenzeni ngcono izinqubo kanye nokunciphisa izindleko.
Izinhlelo Zokusebenza Eziyinhloko
1. Ukusakaza Ukutshalwa Kwezimali Okunembile:Yinto eluhlaza eyinhloko yokwenza amagobolondo ekubunjweni kwe-wax elahlekile, esetshenziswa kungqimba olungemuva kanye nongqimba lokuqinisa. Ihlanganiswe ne-silica sol kanye ne-mullite powder, ingakha igobolondo eliqinile neliqinile, elingamelana nokuguquguquka nokuqhekeka ngesikhathi sokosa nokuthulula, okuqinisekisa ukunemba okuphezulu kwezingxenye ezifana nama-aero-injini turbine blades kanye nama-block enjini yezimoto.
2. Ukulingisa Okunemisebenzi Emikhulu:Njengoba inamandla okubamba ukushisa angu-≥1750℃, ingamelana namazinga okushisa aphezulu ngaphezu kuka-1600℃ futhi imelane nokuguguleka kwensimbi encibilikisiwe kanye ne-slag. Njengesihlabathi sokubumba noma isihlabathi esiyinhloko sezinto ezinkulu zensimbi kanye nezinto zensimbi, ingagcina ubuqotho besikhunta, igweme amaphutha njengokufakwa kwesihlabathi, futhi inciphise izindleko zomsebenzi zokuhlanza ngemva kokuthulula.
3. Ukuphonswa Kwe-Alloy Okukhethekile:Okuqukethwe kwayo okuphansi kwensimbi kanye ne-titanium kanye nokuqina okuhle kwamakhemikhali kungavimbela ukusabela ngama-alloy akhethekile ancibilikisiwe (njengensimbi engagqwali kanye nama-alloy okushisa okuphezulu), kugweme ukungcola kanye nokufakwa kwe-oxide, futhi kuqinisekise ubumsulwa kanye nokuphela kobuso be-castings.
Izinzuzo Eziyinhloko
Isihlabathi se-Mullite sokubumba sixazulula amaphuzu abuhlungu esihlabathini sokubumba sendabuko: ukumelana nokushisa okuphezulu kakhulu (≥1750℃) kuqinisekisa ukuqina kwesikhunta; i-coefficient yokwanda kokushisa okuphansi igcina ukunemba kobukhulu; ukungangeni kwamakhemikhali kuvikela ikhwalithi yokubumba; ukungena komoya okuhle kunciphisa amaphutha njengemigodi yomoya. Kungathuthukisa izinga lokufaneleka kokubumba futhi kunciphise izindleko zangemva kokucutshungulwa, okwenza kube ukukhetha okuhle kwezimo zokubumba ezifunwa kakhulu.
Imininingwane Ejwayelekile Ye-Mesh
Isihlabathi sethu se-mullite sokufaka ubumba sinohlu oluphelele lwezincazelo ze-mesh, ezihlanganisa izidingo zezimo ezahlukahlukene zokufaka ubumba. Osayizi be-mesh evamile bafaka phakathi i-mesh engu-8-16, i-mesh engu-16-30, i-mesh engu-30-60, i-mesh engu-60-80 kanye ne-mesh engu-80-120. Siphinde sinikeze izincazelo ze-mullite powder njenge-mesh engu-200 kanye ne-mesh engu-300, ezingalinganiswa ngqo nezidingo zenqubo ezahlukene zokufaka utshalomali ngokunemba, ukusakaza okunzima, ukusakaza okukhethekile kwe-alloy, njll. Phakathi kwazo, i-mesh engu-30-60 ivame ukusetshenziselwa ukukhiqizwa kwe-slurry esekelayo, kanti i-mesh engu-16-30 ifanele ukusetshenziswa kwezingqimba zokuqinisa, ukuhlangabezana nezidingo ezithile zezinqubo ezahlukene.
Amakhono Esevisi Yokwenza Ngokwezifiso
Sithembele emigqeni yokukhiqiza ehlakaniphile yesimanje kanye nethimba lochwepheshe be-R&D, sinamakhono aqinile okwenza ngokwezifiso. Singakwazi ukwenza imikhiqizo yesihlabathi se-mullite ngokwezifiso ngosayizi okhethekile we-mesh (ongenziwa ngokwezifiso kusukela ku-mesh eyi-10 kuya ku-mesh engu-325), ubumsulwa kanye nokuhlelwa kwezinhlayiya ngokwezinqubo ezithile zokuphonsa zamakhasimende, izinto zokusakaza kanye nezidingo zokusebenza. Kusukela ekukhetheni izinto zokusetshenziswa, ukulungiswa kosayizi wezinhlayiya kuya ekuhlolweni kwekhwalithi, sinikeza insizakalo yenqubo ephelele yomuntu ngamunye, sizivumelanisa nezimo nezidingo ezenzelwe umuntu ngamunye zezimboni ezahlukene njengezindiza, izimoto kanye ne-metallurgy. Ngesikhathi esifanayo, siqinisekisa ukuzinza kokunikezwa kweqembu kanye nokuvumelana kwekhwalithi, sisiza amakhasimende ukuthi athuthukise izinqubo zokukhiqiza futhi athuthukise ukuncintisana komkhiqizo.
