1. DX5D + Z yog dab tsi?
DX57D: Qhov tsawg-} cov txheej txheem steel hlau, muaj nws cov txheej txheem sib sib zog nqus (xws li cov txheej txheem sib sib zog nqus thiab ncab).
+ Z: Qhia tias qhov saum npoo tau kub - dip galvanized (zinc txheej). Lub zinc txheej adheres rau cov hlau nto, muab kev tiv thaiv corrosion.
2. Cov yam ntxwv tseem ceeb
Cov khoom siv hauv paus:
Tsawg cov ntsiab lus carbon (C Tsawg dua li lossis sib npaug zos rau 0.12%), muaj zog ntau dua (feem ntau tsawg dua lossis sib npaug nrog 260 MPA).
Kev tsim kev sib nqus me ntsis kev ua tau zoo (elongation ntau dua los yog sib npaug rau 30%), ua rau nws haum rau cov ntu nyuaj.
Galvanized txheej:
Lub zinc txheej hnyav yog feem ntau 40 - 90 g / m² (ob-ib sab) thiab Z80
Cov kev kho deg yuav suav nrog kev them nyiaj passivation (chromate), roj, lossis tsis muaj kev kho kom tau raws li kev tiv thaiv xeb sib txawv.
3. Cov qauv siv
Cov Qauv Txheej Txheem:
JIS G 3302 (Japanese tus qauv, zoo ib yam li SGCC).
En 10346 (European txheem, coj mus rau DX57D + Z).
GB / T 2518 (Suav tus qauv, zoo ib yam li DC57d + Z).
Zinc txheej Codes: piv txwv, Z60 (60g / m² ntawm ob sab), z80 (80g / m² ntawm ob sab).
4. Cov ntawv thov raug
Automotive: Roj Tso Tsheb Hlau Luam, Chassis Qhov, thiab Kev Txiav Txim Siab Sab Hauv (Xav kom muaj kev muaj peev xwm).
Cov khoom siv hauv tsev: tshuab ntxhua khaub ncaws panels, tub yees tsev tub yees, thiab cua txias.
Kev Tsim Kho: Khaub Ncaws Steel qauv, ru tsev, thiab cov plab (xav tau corrosion tsis kam thiab cov duab ua txiab).
5. Piv nrog cov qhab nia zoo sib xws
Cov Qauv Qauv Txheej Txheem Sib Piv Cov Ntawv Siv
DX57D + Z EN 10346 High D-10346 High DRESSILITY, Nruab Nrab Nruab Nrab Sib Txawv Sib Txawv - teeb qhov chaw
DX54D + Z en 10346 me ntsis qis formability, tus nqi qis dua cov nqi tsheb loj
SGCC JIS G 3302 Zoo ib yam li DX57D, tab sis nrog cov qauv sib txawv Japanese / Kev Tsim Kho
6. Cov Lus Nug
Q1: Yuav DX57D + Z Hloov DX54D + Z?
Yog tias ib feem yuav tsum tau nce siab dua (xws li kev sib sib zog nqus duab), DX57D raug pom zoo; Rau kev tsim cov yooj yim, DX54D muaj kev lag luam ntau dua.
Q2: Yuav ua li cas yuav tsum zinc txheej thickness raug xaiv?
Rau sab nraum zoov lossis siab - av noo ib puag ncig (xws li cov tsev), z80 lossis siab dua yog qhov kev pom zoo; Rau cov khoom siv hauv tsev sab hauv tsev, Z60 yog pom zoo.
Q3: Qhov tsos ntawm zinc spranng rau ntawm sab saum npoo cuam tshuam kev ua tau?
Spangle yog cov qauv crystalline hauv zinc plating. Nws tsis cuam tshuam rau hauv corrosion tsis kam, tab sis tuaj yeem cuam tshuam cov tsos ntawm cov tshuaj tsuag txheej. Kev kho kom me me yuav tsum raug xaiv raws li qhov xav tau.
7. Kev ceev faj
Cia: Zam kom noo kom tiv thaiv zinc oxidation thiab dawb xeb.
Vuam: zinc txheej tso tawm zinc vapor ntawm qhov kub. Qhov cua nkag los yog kev siv cov kev siv vuam tshwj xeeb yog qhov yuav tsum tau ua.
Yog xav paub ntau ntxiv (xws li cov khoom siv rau cov neeg kho mob thiab kev ua kom tau zoo), nws raug nquahu kom xa mus rau cov ntaub ntawv tshwj xeeb lossis cov ntaub ntawv xa khoom.
