Li-filter tsa foam tsa letsopa (CFF)ke dihlahiswa tse nang le masoba a mangata tse sebetsang hantle haholo tse sebediswang haholo diindastering tsa foundry le metallurgical ho hlwekisa tshepe e qhibilihisitsweng, ho fokotsa diphoso tsa ho lahla, ho ntlafatsa qetello ya bokahodimo, le ho ntlafatsa thepa ya mechini. Ka sebopeho se ikgethang sa marangrang a mahlakore a mararo, di hapa dintho tse kenyelleditsweng ka katleho, di tsitsisa phallo, mme di atolosa bophelo ba sesebediswa le hlobo. Bakeng sa bareki ba lefatshe ba batlang ditharollo tse tshepahalang tsa ho sefa, ho utlwisisa karohano le ho iketsetsa ke senotlolo sa ho kgetha sehlahiswa se nepahetseng.
Sehlopha se Seholo sa Li-filter tsa Foam tsa Ceramic
Lifiltara tsa foam tsa letsopa li arotsoe haholo-holo ka thepa, e 'ngoe le e 'ngoe e etselitsoe mocheso o itseng oa ho qhibiliha le mefuta ea tšepe.
1. Sefe ea Foam ea Alumina Ceramic
E tšoeu ka 'mala, e na le mocheso o sebetsang ho fihlela ho 1250°C. Ke sefe se sebelisoang haholo bakeng sa aluminium, litšepe tse kopantsoeng tsa aluminium, koporo le litšepe tse ling tse seng tsa ferrous. E fana ka khanyetso e ntle ea mocheso, phallo e tsitsitseng, le ts'ebetso e theko e phahameng, e loketseng likarolo tsa likoloi, mabili a aluminium le ho lahla ka kakaretso ho se nang ferrous.
2. Sefe ea Foam ea Silicon Carbide (SiC) ea Ceramic
E putsoa kapa e ntšo, e hanela mocheso ho fihlela ho 1500°C. E na le matla a phahameng, ho tsamaisa mocheso hantle, le ho hanyetsa ho bola ho matla. E sebelisoa haholo bakeng sa tšepe e putsoa, tšepe e ductile, le li-castings tse ling tsa alloy. E fokotsa slag le masoba ka katleho, e ntlafatsa chai ea ho lahla le ts'ebetso ea ho sebetsa.
3. Sefe ea Foam ea Zirconia Ceramic
E mosehla, e nang le khanyetso e phahameng haholo mochesong ho fihlela ho 1760°C. E ntshetswa pele ka ho kgetheha bakeng sa tshepe e qhibilihisitsweng, tshepe e sa ruseng, le di-alloy tsa mocheso o phahameng tse kang di-superalloy tse thehilweng ho nickel le cobalt. E fana ka botsitso bo ikgethang maemong a thata, e netefatsa bohloeki bo phahameng bakeng sa ho etsa matsete, difofane le dikarolo tsa bongaka.
Li-filter li ka boela tsa aroloa ka bongata ba li-pore (10–100 PPI), sebopeho (sekwere, se chitja, se khutlonnetsepa), le botenya ho lekana le lebelo le fapaneng la phallo le litlhoko tsa ho nepahala.
Litšebeletso tsa ho Iketsetsa Litšebeliso tsa Liindasteri
Bahlahisi ba litsebi ba tšehetsa ho iketsetsa lintho ka botlalo ho fihlela mela e fapaneng ea tlhahiso le maemo a khethehileng a mosebetsi.
Ho iketsetsa thepa
Khetha har'a alumina, silicon carbide, zirconia, le mekhoa e meng e kopaneng e thehiloeng ho mofuta oa tšepe, mocheso le tikoloho ea mafome.
Boholo le Sebopeho sa ho Itlhophisa
Bolelele, bophara, bophara le botenya bo ikgethileng ho lekana mabokose a sefe, dihlatswa le dikopi tsa ho tshela. Dibopeho tse tlwaelehileng di kenyeletsa diprofaele tse sekwere, tse chitja, tse oval le tse ikgethang.
Ho iketsetsa Sebopeho sa Pore
Kgetha 10–100 PPI ho leka-lekanya ho nepahala ha ho sefa le lebelo la phallo. Mekobo e menyenyane (50–100 PPI) e hapa dintho tse nyane tse kenyelletswang bakeng sa ho lahla dintho tse phahameng; mekobo e menyenyane (10–30 PPI) e netefatsa phallo e boreleli bakeng sa dihlahiswa tse teteaneng.
Ho Etsa Hore Ntlafatso ea Ts'ebetso e be ea Bohlokoa
Kenya dikobo tse thibelang oksideishene, tse thibelang tshenyo, kapa tse matlafaditsweng ho eketsa nako ya tshebeletso le ho ntlafatsa botsitso tlasa maemo a feteletseng.
Li-filter tsa foam tsa ceramic tse etselitsoeng uena li thusa likhoebo ho fokotsa litefiso tsa ho hana, ho fokotsa litšenyehelo tsa tlhahiso, le ho fihlela maemo a boleng a machaba bakeng sa liindasteri tsa likoloi, tsa lifofane, tsa mechini le tsa elektroniki.
Hobaneng U Lokela ho Khetha Bafepedi ba Sefahla sa Foam sa Ceramic sa Litsebi
Boleng bo tsitsitseng, masoba a sa fetoheng, matla a phahameng, le ho hanyetsa ho thothomela ha mocheso li thibela ho robeha nakong ea ts'ebeliso. Ho iketsetsa ka botlalo ho tloha thepa ho ea boholong ho netefatsa ho lumellana ho phethahetseng le ts'ebetso ea hau. Tlhahlobo e tiileng ea boleng le phano e potlakileng ea lefats'e e tšehetsa tlhahiso e tsitsitseng.
Hore na o hloka difilthara tse tloaelehileng kapa tse etselitsoeng wena ka botlalo, ditharollo tsa profeshenale di ntlafatsa boleng ba ho lahla le ho eketsa tlholisano. Ikopanye le rona kajeno bakeng sa kgetho ya thepa, moralo wa ho iketsetsa, le ditharollo tsa ho sefa tse theko e tlase.
