Amashubhu ethusi/ethusi e-CuZn36

I-CuZn36, i-alloy yethusi-zinc, yaziwa kakhulu ngokuthi ithusi. I-CuZn36 brass iyi-alloy equkethe cishe ithusi elingu-64% kanye ne-zinc engu-36%. Le ngxube inokuqukethwe okuphansi kwethusi emndenini wethusi kodwa inokuqukethwe okuphezulu kwe-zinc, ngakho-ke inezakhiwo ezithile zomzimba nezemishini ezifanele ukusetshenziswa kwezimboni ezahlukahlukene. Ngenxa yezakhiwo zayo ezinhle kakhulu zemishini kanye nezakhiwo zokucubungula, i-CuZn36 isetshenziswa kabanzi ekwenziweni kwezingxenye ezahlukene zemishini, izikhonkwane, izipilingi, njll.

Ukwakheka kwamakhemikhali

· I-Lead (Pb): ≤0.05%

· I-Aluminium (Al): ≤0.02%

· Ithini (I-Sn): ≤0.1%

· Ezinye sezizonke: ≤0.1%

· I-Zinc (Zn): Ibhalansi

Izakhiwo zomzimba

Izakhiwo zomzimba ze-CuZn36 zifaka:

· Ubuningi: 8.4 g/cm³

· Indawo yokuncibilika: cishe 920°C

· Umthamo wokushisa othize: 0.377 kJ/kgK

· Imoduli kaYoung: 110 GPa

· Ukushisa okuhambayo: cishe i-116 W/mK

· Ukuqhuba kukagesi: cishe i-15.5% IACS (Indinganiso Yomhlaba Wonke Yokunciphisa Ugesi)

· I-coefficient yokwandisa okuqondile: cishe 20.3 10^-6/K

Izakhiwo zemishini

Izakhiwo zemishini ze-CuZn36 ziyahlukahluka ngokuya ngezimo ezahlukene zokwelashwa kokushisa. Okulandelayo eminye yemininingwane yokusebenza evamile:

·Amandla okudonsa (σb): Kuye ngesimo sokwelashwa kokushisa, amandla okudonsa nawo ayahlukahluka, ngokuvamile aphakathi kuka-460 MPa no-550 MPa.

·Amandla okukhiqiza (σs): Kuye ngesimo sokwelashwa kokushisa, amandla okukhiqiza nawo ayahlukahluka.

·Ukunwebeka (δ): Izintambo ezinobubanzi obuhlukene zinezidingo ezahlukene zokunwebeka. Isibonelo, ngezintambo ezinobubanzi obungaphansi noma obulingana no-4mm, ukunwebeka kumele kufinyelele ngaphezu kuka-30%.

·Ubulukhuni: Ubulukhuni be-CuZn36 busukela ku-HBW 55 kuya ku-110, futhi inani elithile lincike esimweni esithile sokwelashwa kokushisa.

Izakhiwo zokucubungula

I-CuZn36 inezakhiwo ezinhle zokucubungula okubandayo futhi ingacutshungulwa ngokubumba, ukukhipha, ukwelula kanye nokugoqa okubandayo. Ngenxa yokuqukethwe okuphezulu kwe-zinc, amandla e-CuZn36 ayanda ngokwanda kokuqukethwe kwe-zinc, kodwa ngesikhathi esifanayo, ukuhanjiswa kanye nokuqina kwehla. Ngaphezu kwalokho, i-CuZn36 ingaxhunywa futhi nge-brazing kanye ne-soldering, kodwa ngenxa yokuqukethwe okuphezulu kwe-zinc, kufanele kunakwe ngokukhethekile lapho kushiswa.

Ukumelana nokugqwala

I-CuZn36 inokumelana okuhle nokugqwala emanzini, umhwamuko wamanzi, izixazululo ezahlukene zikasawoti kanye noketshezi oluningi oluphilayo. Ifaneleka futhi ezindaweni zomhlaba, zasolwandle kanye nezezimboni. Ngaphansi kwezimo ezithile, i-CuZn36 ingabangela ukuqhekeka kokugqwala kokucindezeleka emoyeni we-ammonia, kodwa lokhu kugqwala kungancishiswa ngokususa ukucindezeleka kwangaphakathi ezimweni eziningi.

Izindawo zokufaka isicelo
Ithusi le-CuZn36 livame ukutholakala kulezi zinsimu ezilandelayo:

Ubunjiniyela bemishini: obusetshenziselwa ukukhiqiza izingxenye ezidinga ubulukhuni obuthile kanye nokumelana nokuguguleka, njengama-valve, izingxenye zephampu, amagiya nama-bearings.

Ubunjiniyela bukagesi: Ngenxa yokuthi ikwazi ukudlulisa ugesi kahle, isetshenziselwa ukukhiqiza izixhumi zikagesi, amasokhethi, njll.

Imihlobiso nemisebenzi yezandla: Ngenxa yezakhiwo zayo ezinhle zokucubungula kanye nombala oyingqayizivele wethusi, i-CuZn36 alloy nayo ifaneleka ekwenziweni kwemihlobiso nemisebenzi yezandla.

I-CuZn36 inezinhlelo zokusebenza eziningi ezahlukene, okuhlanganisa:

·Izingxenye ezidonswe ngokujulile

·Imikhiqizo yensimbi

·Imboni ye-elekthronikhi

·Izixhumi

·Onjiniyela bamakhemikhali

·Izimpawu nemihlobiso

·Izinsimbi zomculo, njll.510

Uhlelo lokwelapha ukushisa

Uhlelo lokwelapha ukushisa lwe-CuZn36 luhlanganisa ukuncibilikisa, ukucima kanye nokushisa, njll. Lezi zindlela zokwelapha ukushisa zingathuthukisa izakhiwo zalo zomshini kanye nokusebenza kokucubungula.

Isifinyezo:

Njenge-alloy yethusi engabizi futhi esebenza kahle kakhulu, i-CuZn36 idlala indima ebalulekile ekusetshenzisweni kwezimboni. Ihlanganisa amandla aphezulu nokusebenziseka kahle futhi ifanelekela izinhlelo zokusebenza ezahlukahlukene zobunjiniyela, ikakhulukazi lapho kukhiqizwa izingxenye ezidinga izakhiwo ezinhle zemishini kanye nokumelana nokugqwala. Ngenxa yezakhiwo zayo ezinhle eziphelele, i-CuZn36 iyinto ekhethwayo ezimbonini eziningi.

Siyakwamukela ukuxhumana nathi ukuthola imininingwane eyengeziwe mayelana namashubhu ethusi noma ethusi!
