Li-filters tsa Ceramic Foam li sebelisetsoa eng? Rarolla Mathata a ho Lahla Liindasteri

Haeba u le ka har'a tšepe ea tšepe, ua tseba hore na liphoso tse bitsang chelete e ngata joalo ka porosity, inclusions, kapa cracks li ka ba joang.Lisebelisoa tsa Ceramic Foam (CFF) ha se "sefe" feela - ke sesebelisoa sa bohlokoa sa ho hloekisa tšepe e qhibilihisitsoeng, ho ntlafatsa bots'epehi, le ho khaola litšila tsa tlhahiso. Empa hantle-ntle li sebelisetsoa eng? Ha re arole lits'ebetso tsa bona tsa bohlokoa ka indasteri le mofuta oa tšepe, e le hore u bone hore na li lumellana joang le mosebetsi oa hau

1. Non-Ferrous Metal Casting: Etsa Aluminium, Copper, Zinc Castings e se nang sekoli.

Litšepe tse se nang ferrous (aluminium, koporo, zinki, magnesium) li sebelisoa haholo likoloing, lisebelisoa tsa elektronike le liphaephe tsa metsi-empa ho qhibiliha ha tsona ho na le monyetla oa ho kenya li-oxide le li-bubble tsa khase. Li-Filters tsa Ceramic Foam li lokisa sena ka ho tšoasa litšila pele li fihla hlobo

Lisebelisoa tsa bohlokoa Mona:

Aluminium Casting (e kholo ka ho fetisisa e se nang ferrous):

Lisefe li tlosa Al₂O₃ oxides le maloanlahla a manyane ho aluminiamo e entsoeng ka ho qhibilihisoa, ho etsa bonnete ba hore li-casts tse boreleli, tse matla. E nepahetse bakeng sa:

Likarolo tsa likoloi:Mabili, litene tsa enjine, matlo a phetiso (mefokolo e fokolang e bolela nako e telele ea bophelo).

Likarolo tsa Sefofane:Lisebelisoa tsa aluminium tse bobebe bakeng sa liforeimi tsa sefofane (li hloka tšepe e hloekileng haholo).

Thepa ea bareki:Aluminium cookware, casings laptop (ha ho na likoli holim'a metsi).

Copper & Brass Casting :

Traps sulfide inclusions le likhechana tsa refractory, ho thibela ho lutla ho:

Likarolo tsa liphaephe:Li-valve, li-fittings, liphaephe (tse bohlokoa bakeng sa ts'ebetso e thibelang metsi).

Likarolo tsa motlakase:Li-connectors tsa koporo, li-terminals (koporo e hloekileng e tiisa hore ho sebetsa hantle).

Zinc & Magnesium Casting:

Lisefe li laola oxide buildup in high-pressure die casting (HPDC) bakeng sa:

Tsa elektroniki:Mehala ea mohala oa zinc alloy, liforeimi tsa lilaptop tsa magnesium (mabota a masesaane ha a hloke sekoli).

Hardware:Lisebelisoa tsa mamati a zinc, likarolo tsa lisebelisoa tsa matla a magnesium (boleng bo tsitsitseng).

2. Ferrous Metal Casting: Lokisa Litšepe, Litšepe Bakeng sa Tšebeliso ea Boima

Litšepe tse nang le tšepe (tšepe, tšepe e entsoeng ka tšepe) li sebetsana le khatello e matla-empa mocheso oa tsona o phahameng oa ho qhibiliha (1500°C+) o hloka lihloela tse thata. Li-Ceramic Foam Filters mona li thibela slag, likaroloana tsa graphite le li-oxide tse senyang matla.

Lisebelisoa tsa bohlokoa Mona:

Ts'epe le Ts'epi ea tšepe:

E mamella ho qhibiliha ha tšepe e chesang ho hlahisa likarolo tse tšepahalang bakeng sa:

Mechini ea indasteri:Li-valve tsa tšepe, 'mele oa pompo, li-gearbox (ha ho na mapetso a ka hare = nako e fokolang).

Kaho:Li-brackets tsa tšepe tse sa hloekang, lihokelo tsa rebar (e hanela kutu).

Thepa ea bongaka:Lisebelisoa tsa ho buoa tse se nang tšepe, lisinki tsa sepetlele (tšepe e hloekileng = ts'ebeliso e bolokehileng).

Cast Iron Casting:

E ntlafatsa microstructure bakeng sa:

Tsa makoloi:Li-brake discs tsa tšepe tse bohlooho, li-crankshaft tsa tšepe tse nang le ductile (ho sebetsana le likhohlano le torque).

Thepa e boima:Likarolo tsa terekere ea tšepe, mehlahare ea crusher (e hloka ho hanyetsa).

Liphaephe:Liphaephe tsa metsi tsa tšepe tse bohlooho (ha ho na ho lutla ho tsoa ho inclusions).

3. Ho Latsoa ka Nako e Phahameng ka ho Fetisisa: Tackle Titanium, Refractory Alloys

Bakeng sa lisebelisoa tse feteletseng (sepakapaka, nyutlelie), moo litšepe li chesang haholo (1800°C+) kapa li sebetsa (titanium), li-filters tse tloaelehileng li hlōleha. Ceramic Foam Filters (haholo-holo e thehiloeng ho ZrO₂) ke eona feela tharollo.

Lisebelisoa tsa bohlokoa Mona:

Titanium Alloy Casting :

Titanium e qhibiliha e sebetsana le lisebelisoa tse ngata-empa li-filters tsa ZrO₂ li lula li sa sebetse, li etsa:

Likarolo tsa sepakapaka:Li-blade tsa enjine ea Titanium, lisebelisoa tsa ho lula sefofaneng (li hloka tšepe e hloekileng haholo bakeng sa bophahamo bo phahameng).

Li-implants tsa bongaka:Liphetoho tsa noka tsa Titanium, ho koaheloa ha meno (ha ho na tšilafalo = biocompatible).

Refractory Alloy Casting :

Lisefa tsa superalloys tse senang ferrous (nickel-based, cobalt-based) bakeng sa:

Ho hlahisa matla:Likarolo tsa turbine ea nickel-alloy (e sebetsana le mocheso oa 1000 ° C+).

Indasteri ea nyutlelie:Zirconium alloy fuel cladding (e hanela mahlaseli le mocheso o phahameng).

Hobaneng Li-filters tsa Ceramic Foam li otla likhetho tse ling?

Ho fapana le mesh ea mohala kapa li-filters tsa lehlabathe, CFFs:

E-ba le sebopeho sa porous sa 3D (ho tšoasa litšila tse ngata, esita le tse nyane).

E mamella mocheso o feteletseng (1200-2200 ° C, ho latela thepa).

Sebetsa ka litšepe tsohle tse kholo (aluminium ho titanium).

Fokotsa litefiso tsa lichelete ka 30-50% (boloka nako le chelete).

Fumana CFF e nepahetseng bakeng sa Nyeoe ea Hao ea Tšebeliso

Hore na o etsa likarolo tsa koloi tsa aluminium, li-valve tsa tšepe e sa hloekang, kapa li-implants tsa titanium, re na le Lisefe tsa Ceramic Foam tse etselitsoeng litlhoko tsa hau. Lisefe tsa rona li kopana le litekanyetso tsa ISO/ASTM, 'me sehlopha sa rona se u thusa ho khetha thepa e nepahetseng (Al₂O₃ bakeng sa aluminium, SiC bakeng sa tšepe, ZrO₂ bakeng sa titanium).

Ikopanye le rona kajeno bakeng sa sampole ea mahala le quote e tloaelehileng. Khaotsa ho loants'a liphoso tsa ho lahla - qala ho etsa likarolo tse se nang sekoli ka CFF!
