{{0 {}} Dab tsi yog 3004 aluminium siv rau?
Kev Lag Luam Ntim:
Dej haus poom, ntim khoom noj, thiab ntawv ci thiab ntawv ci (vim muaj cov khoom siv nyiaj txiag thiab thaiv cov khoom).
Kev Tsim Kho:
Cov ntawv vov tsev, siding, muaj cov duab kos, thiab kws kho vajtse tiv thaiv) {}}}
Tsheb thauj mus los:
Tsheb Shocks, Tsheb Caj Hlau, thiab Nkoj Lub Teeb Cog Cog Cog Cog Lus Hauv (Lub teeb yuag + corrosion tsis kam).
Siab Hlab:
Tso tsheb hlau luam rau cov kua thiab roj av (lub zog nruab nrab + formability) .
Cov neeg siv khoom lag luam:
Cov cuab yeej siv cov cuab yeej siv, ua noj ua noj ua mov, thiab ntim khoom .
2. Dab tsi yog cov khoom ntawm Al 3004?
Neeg kho tshuab zog: tensile zog yeem ntawm 170 rau 240 MPA (ua kom haum rau cov khoom siv thauj khoom uas yuav tsum tau ua.
Corrosion Kuj: Zoo heev depability hauv atmospheric, thiab ntau txheej oxide txheej uas tsim ntawm nws cov npoo .
Thermal thiab hluav taws xob conductivity: muaj cov cua sov muaj nqis (155 w / min ·
Ductility: Cov neeg muaj peev xwm siab ua rau kev sib sib zog nqus teeb duab, khoov, thiab dov mus rau hauv cov duab hlau nyuaj, zoo tagnrho rau daim ntawv hlau fabrication.
Lub Hnav Tsho: Nrog lub ntom ntom ntawm 2 {. 7 g / hack, nws muaj cov nyiaj khaws cia tsis muaj zog piv.
{{0 {}} Dab tsi yog qhov sib xyaw ua ke ntawm txhuas alloy 3004?
Aluminium (AL): PAST HLAU (~ 95 . 8-97.6%).
Manganese (MN): 1 {{{}} 0-1.5% (ntxiv dag zog rau alloy thiab txhim kho corrosion tsis kam).
Magnesium (MG): 0 . 8-1.3% (txhim kho lub zog thiab ua haujlwm tawv tawv).
Silicon (Si): tsawg dua lossis sib npaug ntawm 0 {. 35%, kev txwv tsis pub siv lub ductility).
Hlau (FE): tsawg dua lossis sib npaug ntawm 0 {.} 7% (impurity, tswj cov qauv nplej).
Lwm cov ntsiab lus: Cu, ZN, TI (txhua tsawg dua lossis sib npaug ntawm 0 {. 25%, ib qho ntxiv ntxiv rau cov txheej txheem).
{{04. yog 3004 txhuas muaj kev nyab xeeb rau kev ua noj?
Kev Nyab Xeeb Hauv Paus:
3004 tsis muaj cov khoom siv toxic (e . g., cadmium) {}}
Txhuas yog siv dav hauv cov khoom noj ntim khoom (poom, ntawv ci) thiab cookware (lauj kaub (lauj kaub, cov tais).
Cov ntaub ntawv Alloy ib qho ruaj khov, tsis muaj kev cuam tshuam txhuas oxide txheej (al₂o₃) uas tiv thaiv kev sib cuag ncaj qha nrog zaub mov.
Cov kev ceev faj:
Cov khoom noj acidic: Zam kev sib chwv rau cov khoom xyaw high acid (5 mg / kg zaub mov).
Cov kev kho deg: yog tias cov alloy yog anodized lossis coated, xyuas kom cov txheej yog cov xim tsev-qib (e}
Hnav thiab khawb: Cov chaw khawb yuav nthuav tawm ntau cov chaw, tab sis li qub (ntxuav, kev puas tsuaj me me) tsis zoo li yuav tsum muaj kev pheej hmoo .
Kev cai tau txais kev cai:
3004 Aluminium yog pom zoo rau cov zaub mov sib chwv los ntawm orgaNizations zoo li Asmeskas FDA thiab European Union (EC 1935/2004).
