Tikolohong e nang le mocheso o phahameng le ho senyeha ho hoholo ha tlhahiso ea samente, ts'ebetso ea likarolo tsa lisebelisoa tsa mocheso e khetholla ka ho toba katleho ea tlhahiso, polokeho ea ts'ebetso le taolo ea litšenyehelo. Jwalo ka karolo ea mantlha ea mocheso, boleng ba lipeipi tsa tšireletso ea thermocouple le lipeipi tsa phapanyetsano ea mocheso bo bohlokoa. Kajeno, re hlahisa sehlahisoa se fetolang papali bakeng sa limela tsa samente lefatšeng ka bophara:liphaephe tsa microcrystalline tsa silicon carbide— e entsoe ho mamella maemo a thata ka ho fetisisa le ho phahamisa tlhahiso ea hau ea samente ho ea fihla maemong a macha.
Hobaneng ha Li-Tube tsa Silicon Carbide Microcrystalline li le Bohlokoa bakeng sa Limela tsa Samente
Tlhahiso ea samente e kenyelletsa lits'ebetso tse rarahaneng tse kang ho calcination ea thepa e tala, ho sintering ha clinker, le ho sila samente, moo lihokelo tsa bohlokoa tse kang rotary oven, preheater le cooler li sebetsang mochesong o fetang 1200°C. Li-tube tsa tšepe kapa tsa ceramic tsa setso hangata li na le bothata ba ho tsofala ka potlako, ho bola, kapa ho hloleha ho ts'oaroa ke mocheso, e leng se lebisang ho li nkeloa sebaka khafetsa, nako e sa reroang ea ho se sebetse, le litšenyehelo tse eketsehileng tsa tlhokomelo. Li-tube tsa silicon carbide microcrystalline, tse nang le thepa ea tsona e ikhethang ea thepa, li sebetsana hantle le lintlha tsena tsa bohloko.
Melemo ea Bohlokoa ea Li-Tube tsa Rōna tsa Silicon Carbide Microcrystalline
1. Khanyetso e Ikhethang ea Mocheso o Phahameng
Li-tube tsa rona tsa silicon carbide microcrystalline li na le ntlha ea ho qhibiliha e fetang 2700°C 'me li ka sebetsa ka botsitso nako e telele mochesong o fihlang ho 1600°C. Esita le mochesong o feteletseng oa sebaka se tukang sa onto ea rotary, li boloka botsitso ba sebopeho ntle le ho fetoha kapa ho petsoha. Sena se netefatsa tekanyo e tšepahalang ea mocheso le ts'ebetso ea phetisetso ea mocheso, ho felisa kotsi ea ho hloleha ha lisebelisoa ho bakoang ke tšenyo ea mocheso o phahameng.
2. Ho Hloahloa ha ho Hloa le ho Hanela ho Ts'enyeha ho Phahameng
Tlhahiso ea samente e hlahisa palo e kholo ea likaroloana tse khorofoang (joalo ka phofo e tala, clinker, le lerōle) le likhase tse senyang (joalo ka CO₂, SO₂). Thepa ea silicon carbide microcrystalline e na le boima ba Mohs ba 9.2, e latelang daemane feela, e leng se etsang hore e hanele ho khoholeha haholo. Ho feta moo, ha e na matla ho boholo ba li-acid, alkali le likhase tse senyang, e thibela khoholeho ea liphaephe ka katleho le ho atolosa bophelo ba tšebeletso ka makhetlo a 3-5 ha e bapisoa le lihlahisoa tsa setso.
3. Khanyetso e Hlollang ea Thermal Shock
Hangata dimela tsa samente di ba le diphetoho tse potlakileng tsa mocheso nakong ya ho qala, ho tima, kapa ho lokisa mojaro. Di-tube tsa silicon carbide microcrystalline di na le coefficient e tlase ya katoloso ya mocheso le kganyetso e matla ya ho tshoha ha mocheso, tse kgonang ho mamella diphetoho tse tshohanyetso tsa mocheso tse fetang 800°C ntle le ho petsoha. Thepa ena e fokotsa haholo makgetlo a ho nkela sebaka ha tube ka lebaka la ho tshoha ha mocheso, e leng se ntlafatsang ho tswela pele ha tlhahiso.
4. Ho nepahala ha ho tsamaisa mocheso o phahameng le ho lekanya
Bakeng sa lipeipi tsa tšireletso ea thermocouple, tekanyo e nepahetseng ea mocheso ke ea bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea calcination. Thepa ea silicon carbide microcrystalline e na le conductivity e ntle ea mocheso, e netefatsang hore mocheso o lemohuoang ke thermocouple o tsamaellana le mocheso oa sebele oa tikoloho ea tlhahiso. Sena se thusa limela tsa samente ho fihlela taolo e nepahetseng ea ts'ebetso ea ho sintering, ho ntlafatsa boleng ba clinker, le ho fokotsa tšebeliso ea matla.
Likopo tsa Bohlokoa Tlhahisong ea Samente
Li-tube tsa rona tsa silicon carbide microcrystalline li sebelisoa haholo maemong a fapaneng a batloang haholo lifemeng tsa samente, ho kenyeletsoa:
- Setofo sa Rotary:Jwalo ka diphaephe tsa tshireletso ya thermocouple bakeng sa ho lekanya mocheso wa sebaka se tukang le sebaka sa phetoho, ho netefatsa tshebetso e tsitsitseng ya onto.
- Sehatsetsi le Sebolaya-mocheso:E sebelisoa e le liphaephe tsa phapanyetsano ea mocheso le liphaephe tse lekanyang mocheso, e hanela ho hohlobana le ho bola ho bakoang ke phofo e tala e nang le mocheso o phahameng le khase ea flue.
- Se pholileng:Bakeng sa ho lekanya mocheso le phetisetso ea mocheso ts'ebetsong ea ho pholisa ea clinker, ho mamella tšusumetso ea likaroloana tsa clinker tse mocheso o phahameng.
- Mokero oa Moea o Chesang:Jwalo ka diphaephe tsa tshireletso tse lekanyang mocheso, tse ikamahanyang le tikoloho ya mocheso o phahameng le o lerōle ya diphaephe tsa moya o chesang.
Ke Hobane'ng ha U Lokela ho Khetha Li-Tube tsa Rona tsa Silicon Carbide Microcrystalline?
Ka lilemo tsa boiphihlelo lipatlisisong, nts'etsopele le tlhahisong ea thepa ea carbide ea silicon, re khomarela litekanyetso tse tiileng tsa taolo ea boleng ho tloha khethong ea thepa e tala ho isa tlhahlobong ea sehlahisoa se felileng. Li-tubes tsa rona tsa microcrystalline tsa silicon carbide li etsoa ka theknoloji e tsoetseng pele ea ho sintering, ho netefatsa sebopeho sa kristale se ts'oanang, ho ba le bongata bo phahameng le ts'ebetso e tsitsitseng.
Ho phaella moo, re fana ka ditharollo tse ikgethileng ho latela ditlhoko tse ikgethang tsa dimela tse fapaneng tsa samente, ho kenyeletswa boholo bo fapaneng, dibopeho le mekgwa ya kgokelo. Sehlopha sa rona sa botekgeniki ba profeshenale se fana ka ditherisano tsa pele ho thekiso le tshehetso ya botekgeniki kamora thekiso, ho o thusa ho rarolla mathata afe kapa afe a kopanang le ona tshebetsong ya kopo.
