Lub zog tensile: Txog {250-300 mpa mpa ci hauv annealed xeev, tsa rau {1}} mpa tom qab ua haujlwm txias.
Kev Txiaj Ntsig: Annealed State ntau dua los yog sib npaug rau 45%, tom qab ua haujlwm txias txog {}}}) (siab heev).
1.3 corrosion tsis kam
Ib puag ncig dav dav: Zoo corrosion tsis kam nyob rau hauv huab cua qhuav, hauv dej nruab nrab lossis roj.
Qaum \/ Corrosive ib puag ncig:
Tsawg Zinc Cov Ntsiab Lus, Duzincification Corrosion yog qhov tsis muaj zog tshaj qhov siab Zinc Brass (piv txwv li C26000).
Zam kev sib cuag ntev nrog dej hiav txwv, acidic media lossis chlorine-muaj chaw ib puag ncig, txwv tsis pub siv saum npoo av (piv txwv li plating plating, pleev xim).
2 daim ntawv thov MAINAL
2.1 Kev Tsim Kho Thiab Kho Kom Zoo Nkauj
Kev kho vajtse zoo nkauj: Qhov rooj daws teeb meem, teeb nkhaus, cov ntawv kos duab vajtse (liab liab xim zoo nkauj thiab oxidation resistant).
Cov duab puab duab kos duab: Duab puab sab nraum zoov substrate (yuav tsum tau coated nrog cov txheej antator).
2.2 hluav taws xob thiab hluav taws xob hluav taws xob thiab hluav taws xob
Cov Cheebtsam ua tau: Plug cov neeg tiv toj, txuas cov ntawv (cov xwm txheej qis dua).
Cov khoom siv kub dissipation: kub so, cov hws ntawm cov raj (thermal conductivity zoo dua li cov hlau qub).
2.3 Kev Raug Raug
Cov khoom siv txias: shrapnel, gaskets, retlows (cia siab rau kev ua siab loj).
Cov kav dej fittings: li qub, cov yeeb nkab fittings (rau cov dej tshiab dej).
2.4 Cov Khoom Siv Khoom Siv
Cov Suab Paj Nruag Sib Tham: Trumpet Pistons, Saxophone Yuam Sij (Resonance resonance yam ntxwv).
Myitation cov khoom lag luam kub: cov khoom plig, cov hniav nyiaj hniav kub (tus nqi qis dua li tooj liab dua, yooj yim rau cov ntsiab lus).
3. Machining thiab ua cov lus pom zoo
Kev ua haujlwm txias: Tsim nyog rau stamping, ncab, ua haujlwm hardening yuav tsum tau annealed (annealing kub ntawm 500-700 degree).
Vuam: Pom zoo nyiaj Brazing lossis Argon arc vuam, kom tsis txhob volatilization ntawm zinc vapor (zinc boiling taw tes ntawm 907 degree).
Nto Kho:
Tshuaj lom neeg polishing: txhim kho cov xim liab xim.
Electropated nickel \/ chromium: los txhim kho cov hnav thiab corrosion tsis kam.
Passivation: rau ib puag ncig sab nraum zoov kom tiv thaiv oxidation.
4. Kev sib piv nrog lwm daim brasses
Cov ntsiab lus tooj liab (%) Cov yam ntxwv raug tsim nyog muaj xwm txheej sib txawv
C {23000 84-86 kev ua siab loj, liab tooj liab xim, nruab nrab lub zog hniav, cov khoom siv tau txias.
C 26000 68-71 Lub zog siab, muaj xim daj, qaug zog qaug zog, screws, muaj cov screads, heev loaded txheej txheem.
C 22000 88-91}} Sib ze dua rau cov tooj liab zoo nkauj, kev ua haujlwm zoo nkauj nrog kev sib cav sib xyaw ua ke (piv txwv li cov mos txwv mos mos).
H 62 60-63 Lub zog siab, tus nqi qis, tsis zoo, cov qauv tsis zoo dav dav-hom phiaj txheej xws li li qub thiab screws.
5. Sau ntawv
Kev tiv thaiv ib puag ncig: txhuas cov ntsiab lus tsawg dua los yog sib npaug rau kev ua raws cai, tsim nyog rau cov ntawv pov thawj kev sib chwv (haum rau cov ntawv pov thawj ntxiv).
Cia: Zam kom tsis muaj kev sib cuag nrog cov acidic lossis ntsev kom tsis txhob muaj oxidation thiab discoloration.
