Isandhi yamullite: Imateriali yezinkundla ephakeme yokuphefumula yokusebenza kwezindlela zokufaka ngokuphelele nezindustria

Ukwethulwa Komkhiqizo

I-Mullite Sand yiyinkimbinkimbi esikhulu se-aluminosilicate esisebenzisa kakhulu kwezindlela zokufaka izinto ngokupheleleyo, ukuzalisa amathuba, ukuzalisa amathuba okusebenza kwezinkinga, ukuzalisa amathuba okwesikili nezinye izindlela zokusebenza emaphakathi aphakeme. Ngokuthula kwezinsuku zokuphatha, ukuphakama kokuphakama kwemithombo, ukuthula kwezinsuku zokuphatha kwezinkinga nokuhlawulwa kokubeka izinkimbinkimbi ngokupheleleyo, i-Mullite Sand isinika umsebenzi othembekile kwezindlela zokusebenza ezihlukene.

I-Mullite Sand isenzelwa ngokuvamile kusuka kwezinkimbinkimbi zokuzalisa i-aluminosilicate ezikhethiwe ngendlela ephambanayo ekuncishiseni, ukuphakama kwezinkinga, ukuchitha, ukususa amathambo nokuqondisa ukubeka izinkimbinkimbi ngokupheleleyo. Ukuphakama kwezinkinga kusiza ekuthuthukiseni isimo sokusebenza kwezinkinga, futhi ukuchitha okulandela kusiza ekuthinteni ukubeka izinkimbinkimbi ngokupheleleyo kuzindlela zokusebenza ezahlukene.

Kusukela kwezindlela zokufaka amasimbi, ukulingana kwesayizi yamaphakathi kuyisisekelo esikhulu ngoba amakhaya amabili we-shell yaseceramic ayidinga amaphakathi anamahlelo ahlukene. Ngakho-ke, i-Mullite Sand ingatholakala ngemiphumela eminingi, kubanzi kwe-10–20 Mesh, 16–30 Mesh, 30–60 Mesh, 50–80 Mesh futhi amagrade amancane kune-200 Mesh. Amakhaya amahlukene angakhethwa ngokwesifundo sokufaka amasimbi, isivinini sesifunda sokufaka amasimbi futhi ukugcina kwesikhephe sokufaka amasimbi.

Ngoba yinkhomo yezinto ezinamandla, i-Mullite Sand inikeza abasika izimpilo eziphelele kuzo zizindlela zokusebenza apho kudingeka ukuthintana kwezintando ezide, ukulingana kwesilinganiso futhi ukulingana kwesayizi yamaphakathi.

Ukusebenzisa Amahluko

1. Ukufaka amasimbi okuhle

Okunengqondo kakhulu kwezindlela zokusebenza kwe-Mullite Sand kukufaka amasimbi okuhle, ikakhulu ukufaka amasimbi okuhle ngokwesibonelo sokufaka amasimbi ngokwesibonelo sokufaka amasimbi ngokwesibonelo sokufaka amasimbi. Kuphrocesi yokwakha i-ceramic shell, i-mullite sand ingasebenzisa njengezinto zokufaka amasimbi kwezikhaya zokuphambuka futhi kwezikhaya zokubhala.

Izinkulungwane zezinkulungwane ezihlukahlukene zinakukhethwa ngokubonakala kwezindlela zokwakha isheli. Isibonelo, i-30–60 Mesh ne-16–30 Mesh ziyasebenzisa kakhulu kwezindlela zokuphakama nokuthutha, ngakho-ke ipowda yomullite engeziwe inakufakwa emagumbini. Ukukhetha kwezinkulungwane zezinkulungwane kusiza ukufikwa kwezindawo zokuphakama, ukugcina kwezindawo zokuphuma kwezinto, nokubonakala kwezindawo zokuphakama.

Umullite Sand uyasebenza kwezindlela zokuzilima okuhle ekuzilimweni kwezincwadi zezincwadi, izincwadi zezincwadi, izincwadi zezincwadi nezinye izincwadi zezincwadi lapho izincwadi zezincwadi eziphambili zinadingeka.

2. Ukuzilima nokuzilima

Umullite Sand unakusebenzisa njengesiqephu sokuzilima ekuzilimweni. Ubukhachule bokuphakama kwayo kusiza umkhosi okuzilima noma isheli ukubona ubukhachule bakhe ngokuphakama kwezindlela zokuphakama nokuzilima kwamazwe.

Lezinto liyakwenzeka kubhukhi zokufaka emaphandleni nezinhlangano zokufaka ngokwezifundo zokugcina wekhalasi. Ukuzimisa kwakho kwezinkulungwane kwenza ukuthi abahleli bakhetha izigaba ezifanele kuzo zonke izindlela zokufaka.

3. Izinkulungwane Zokuphepha

Ngokuba kunezinkulungwane zokuphepha, isandhi sokumullite siyasebenza ekupheleni kwezinkulungwane zokuphepha nezinqakamba zokuphepha kwezintambo. Siyakwenzeka njengezinto ezingaphansi noma njengezinto ezikhulu kwezinkulungwane zokuphepha lapho ukuphepha kwezintambo nokuphepha kwezintambo kuyisisekelo esibalulekile.

4. Izinkulungwane Zokufaka Nezinkulungwane Zokufaka Kusuka Emaphandleni

Izinkulungwane zokumullite ziyasebenzisa kwezinkulungwane nezinkulungwane zokufaka kusuka emaphandleni. Izigaba ezincane ziyakwenzeka kuzo zizinhlangano zokufaka noma kuzo zizinhlangano zokufaka, futhi izigaba ezinkulu ziyakwenzeka lapho kufuneka kubhekwa kwezinhlangano zokufaka.

Ipharamitha yomkhiqizo

Ukuguqula kwemithambo yezinkulungwane nezinkinga zokusebenza kuzoba kuhlukeneyo ngokwehlobo lwesikhundla nangokwezinkinga zokuproducwa. Iziprojekthi zesand eziyi-mullite ziyasebenzisa i-alumina ne-silica njengamaphuzu amaningi, nangokuvimbela kwezinkulungwane zomphakathi wokugcina ukuphakama kwezinkulungwane nangokuvimbela kwezinye izimpahla ezingenabizo. Ezinye izihlobo zokuthengiswa zikubona i-Al₂O₃ ngaphezu kwe-42–47%, i-SiO₂ ngaphezu kwe-51–53%, nokuphakama kwezinkulungwane ngaphezu kwe-1,750°C. Izinombolo zokweshwa ziyakuboniswa ngokuthi ziyisifundo sezinto zokusebenza noma isitifiketi sokukhula.
