Saib xyuas zoo corrosion zoo: haum rau kev siv nyob rau hauv ib puag ncig ntub dej, acidic muaj kev muaj kev lag luam xws li lub tsev sab nrauv thiab cov twj xa khoom.
Txhim kho cov txheej txheem: cuzn20 muaj cov xim zoo dua li cov xim zinc zoo dua, thiab ua tau zoo hauv stamping, khoov thiab lwm yam machining txheej txheem.
1.2. Cawv ntawm cov kab kawm ntawm kev ua tau zoo
Lead (PB): tsawg dua lossis sib npaug ntawm 0. 05%}. 05%}.
Hlau (FE): tsawg dua los yog sib npaug rau 0. 05%}. 05%, los txhim kho cov khoom siv, haum rau cov khoom siv kho tshuab.
Tin (sn): tsawg dua lossis sib npaug rau 0. 1%, txhim kho cov corrosion tsis kam ntawm Corrosion thiab kev kub ntxhov thiab kub thiab txias.
2. Lub cev thiab cov kws kho tshuab ntawm Cuzn20 tooj dag
2.1 Cov Khoom Siv Lub Cev
Cuzn20 tooj dag tau ua tau zoo heev hauv hluav taws xob conduction, thermal conductivity thiab corrosion Kuj:
Ntom ntom: 8.7 g /m³
Melting taw tes: 900 - 920 degree
Hluav taws xob conductivity: kwv yees. 36% IACS (International Analealed Tooj Liab Qauv Qauv)
Thermal conductivity: kwv yees. 120 w / mk
Coefficient ntawm thermal expansion: 19 × {1}} ⁶ K-¹
2.2 Cov Khoom Siv Neeg Kho Tshuab
Cuzn20 Brass muaj cov khoom siv kho dua lub sijhawm zoo thaum tswj hwm kev ua kom zoo thiab haum rau cov ntaub ntawv muaj kev lag luam rau cov khoom siv hluav taws xob:
Tensile Lub Zog (RM): {350 - 450 mpa mpa
Paib lub zog (rp 0. 2): ntau dua los yog sib npaug rau 180 mpa
Elongation (A50): Ntau dua lossis sib npaug rau 25%
Hardness (HBW): 100 - 140
Piv rau Cuzn10 thiab Cuzn15, cuzn15, cuzn20 muaj ntau ntxiv rau cov lus muaj zog, hnav tsis kam thiab kev thov kom sib txhuam, siab thiab cov neeg kho tshuab thauj khoom yuav tsum muaj.
Kev txhim kho yav tom ntej:
Nrog rau kev txhim kho kev lag luam Automation thiab cov khoom siv hluav taws xob ua tau zoo yuav txuas ntxiv ntxiv, thiab kev ua lag luam rau kev lag luam ntawm Cuzn20 yuav txuas ntxiv mus nthuav dav.
3.3. Kev siv hluav taws xob thiab hluav taws xob kev lag luam
Cuzn20 muaj cov hluav taws xob zoo thiab oxidation tsis kam, uas ua rau nws siv hauv kev lag luam hauv hluav taws xob thiab hluav taws xob.
Daim Ntawv Thov:
Cov Hluav Taws Xob Hluav Taws Xob thiab cov chaw tsim hluav taws xob: siv hauv kev tsim cov khoom siv tsis tshua muaj hluav taws xob, qib siab kev ntseeg tau hluav taws xob txuas, cov chaw nres tsheb, relay tiv tauj thiab lwm yam.
Cov ntaub thaiv hluav taws xob: Rau cov ntaub thaiv hluav taws xob tiv thaiv kab ke hauv cov khoom siv hluav taws xob siab, xws li cov cuab yeej siv hluav taws xob, khoos phis tawj thiab cov khoom siv sib txuas lus.
Kev txhim kho yav tom ntej:
Nrog rau cov khoom sib txuas lus 5G, cov cuab yeej txawj ntse ntse, thiab cov kev thov hluav taws xob tshiab, qhov kev thov rau Cuzn20 daim ntaub ntawv hauv kev lag luam hluav taws xob yuav nce mus ntxiv.
3.4. Kev Lag Luam Automotive
Daim Ntawv Thov:
Automotive Cua Txias Zog: Cuzn20 yog siv rau kev tsim cov tso tsheb hlau luam dej, lub cua sov so dej, cua txias pipes thiab lwm yam kom ntseeg tau tias kub ua kom sov.
Roj xa khoom system: Vim tias nws zoo heev corrosion tsis kam, cuzn20 yog tsim nyog rau cov roj kab, li qub, tshuab lub cev thiab lwm yam.
Kev txhim kho yav tom ntej:
Nrog rau kev txhim kho cov tsheb hluav taws xob tshiab thiab cov tsheb hluav taws xob, daim ntawv thov ntawm Cuzn20 yuav tau txuas ntxiv mus rau cov tsheb sib txuas tau txuas rau cov tsheb hluav taws xob.
