Machubu a CuZn36 Brass / Copper

CuZn36, chopangira cha mkuwa ndi zinc, chimadziwika kuti mkuwa. CuZn36 brass ndi chopangira cha mkuwa chokhala ndi pafupifupi 64% ndi zinc 36%. Chopangira cha mkuwachi chili ndi mkuwa wochepa m'banja la mkuwa koma chili ndi zinc yambiri, kotero chili ndi zinthu zina zakuthupi ndi zamakaniko zoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Chifukwa cha zinthu zake zabwino kwambiri zamakaniko ndi zinthu zopangira, CuZn36 imagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana zamakaniko, zomangira, masika, ndi zina zotero.

Kapangidwe ka mankhwala

Kapangidwe ka mankhwala a CuZn36 ndi motere:

· Chitini (Chizindikiro): ≤0.1%

· Zina zonse: ≤0.1%

· Zinc (Zn): Kulinganiza

Katundu wakuthupi

Makhalidwe enieni a CuZn36 ndi awa:

· Kuchuluka: 8.4 g/cm³

· Malo osungunuka: pafupifupi 920°C

· Mphamvu yeniyeni ya kutentha: 0.377 kJ/kgK

· Modulus ya Young: 110 GPa

· Kutentha kwa mpweya: pafupifupi 116 W/mK

· Kuyendetsa magetsi: pafupifupi 15.5% IACS (International Demagnetization Standard)

· Kuchuluka kwa kukula kwa mzere: pafupifupi 20.3 10^-6/K

Katundu wa makina

Kapangidwe ka makina a CuZn36 kamasiyana malinga ndi momwe kutentha kumakhalira. Izi ndi zina mwazomwe zimachitika:

·Kulimba kwa mphamvu (σb): Kutengera ndi momwe kutentha kumagwiritsidwira ntchito, mphamvu ya mphamvu ya mphamvu imasiyananso, nthawi zambiri pakati pa 460 MPa ndi 550 MPa.

·Kulimba kwa zokolola (σs): Kutengera ndi momwe kutentha kumagwiritsidwira ntchito, mphamvu ya zokolola imasiyananso.

·Kutalikirana (δ): Mawaya amitundu yosiyanasiyana ali ndi zofunikira zosiyanasiyana pakutalikirana. Mwachitsanzo, mawaya okhala ndi mainchesi ochepera kapena ofanana ndi 4mm, kutalika kuyenera kufika pa 30%.

·Kulimba: Kulimba kwa CuZn36 kumayambira pa HBW 55 mpaka 110, ndipo mtengo wake umadalira momwe kutentha kumagwiritsidwira ntchito.

Katundu wokonza

CuZn36 ili ndi mphamvu zabwino zokonzera zinthu zozizira ndipo imatha kukonzedwa pogwiritsa ntchito forging, extrusion, stretching ndi cold rolling. Chifukwa cha kuchuluka kwa zinc, mphamvu ya CuZn36 imawonjezeka ndi kuchuluka kwa zinc, koma nthawi yomweyo, conductivity ndi ductility zimachepa. Kuphatikiza apo, CuZn36 imathanso kulumikizidwa ndi brazing ndi soldering, koma chifukwa cha kuchuluka kwa zinc, chisamaliro chapadera chiyenera kuperekedwa polumikiza.

Kukana dzimbiri

CuZn36 ili ndi kukana dzimbiri kwa madzi, nthunzi ya madzi, njira zosiyanasiyana zamchere ndi zakumwa zambiri zachilengedwe. Iyeneranso kugwiritsidwa ntchito m'malo okhala ndi nthaka, m'nyanja ndi m'mafakitale. Pazifukwa zina, CuZn36 ikhoza kuyambitsa ming'alu ya dzimbiri ku mlengalenga wa ammonia, koma dzimbirili limatha kuchepetsedwa pochotsa kupsinjika kwamkati nthawi zambiri.

Madera ogwiritsira ntchito
Mkuwa wa CuZn36 umapezeka kwambiri m'magawo otsatirawa:

Uinjiniya wa makina: umagwiritsidwa ntchito popanga zida zomwe zimafuna kuuma ndi kukana kuwonongeka, monga ma valve, zida zopopera, magiya ndi ma bearing.

Uinjiniya wamagetsi: Chifukwa cha mphamvu yake yabwino yoyendetsera magetsi, imagwiritsidwa ntchito popanga zolumikizira zamagetsi, masoketi, ndi zina zotero.

Zokongoletsera ndi zaluso: Chifukwa cha luso lake labwino lokonza zinthu komanso mtundu wapadera wa mkuwa, CuZn36 alloy ndiyoyeneranso kupanga zokongoletsa ndi zaluso.

CuZn36 ili ndi mapulogalamu osiyanasiyana, kuphatikizapo:

·Zigawo zokokedwa mozama

· Zinthu zachitsulo

· Makampani amagetsi

· Zolumikizira

·Ukachenjede wazitsulo

· Zizindikiro ndi zokongoletsa

·Zida zoimbira, ndi zina zotero.510

Dongosolo lothandizira kutentha

Njira yochizira kutentha ya CuZn36 imaphatikizapo kuphimba, kuzimitsa ndi kutenthetsa, ndi zina zotero. Njira zochizira kutentha izi zitha kupititsa patsogolo mphamvu zake zamakaniko ndi magwiridwe antchito ake opangira.

Chidule:

Popeza ndi aloyi yamkuwa yotsika mtengo komanso yogwira ntchito bwino, CuZn36 imagwira ntchito yofunika kwambiri pa ntchito zamafakitale. Imaphatikiza mphamvu zambiri ndi kuthekera kokonza bwino ndipo ndi yoyenera ntchito zosiyanasiyana zauinjiniya, makamaka popanga zida zomwe zimafuna mphamvu zabwino zamakanika komanso kukana dzimbiri. Chifukwa cha mphamvu zake zabwino, CuZn36 ndiye chinthu chomwe chimakonda kwambiri m'mafakitale ambiri.

Takulandirani kuti mulumikizane nafe kuti mudziwe zambiri zokhudza machubu a mkuwa kapena mkuwa!
