1.How rau ua kom pom kev sib sib zog ua tau zoo tshaj plaws?
Tsawg tawm tswv yim lub zog (feem ntau tsawg dua lossis sib npaug rau 180 MPa) + cov khoom siv siab heev (ntau dua lossis sib npaug
Siab r - tus nqi (feem ntau ntau dua los yog sib npaug lossis sib npaug zos (tiv thaiv cov khoom siv tawv me me Cov khoom siv no yog tsim nyog tshwj xeeb rau kev tsim cov loj, tob- Cov txheej txheem} kev kos duab xws li lub qhov rooj thiab hoods.
Tsis tas li ntawd, DX54D cov txheej muaj cov nplaum muaj zog heev, tiv thaiv qhov kev xav tau ntawm kev siv lub cim thiab tawg,} plating thiab txo cov nqi ntau lawm.
2.Qhov kev cuam tshuam twg ua rau kev mob siab rau txoj kev pabcuam lub neej ntawm lub tsheb?
Thaum cov steel saum npoo yog khawb, zinc txheej corrodres ua ntej lub hauv paus steel (hlau), tiv thaiv cov hauv paus hlau los ntawm xeb.
Cov txheej txheej zinc kuj tseem tseem ua cov yeeb yaj kiab tuab (zno, zn) ₂), oxygen los ntawm cov hauv paus steel, txhim kho cov khoom tivthaiv cov xeb.
Cov ntaub ntawv qhia tau tias lub tsheb lub cev siv tau siv DX54D muaj qhov tsim nyog sab nraum zoov ntawm lub cev, tsis muaj kev phom sij (Uncalvanized
3.How hloov chaw vuam zoo thiab pleev xim rau lub tsheb loj rau tsheb ntau lawm?
Weldability: Thaum lub galvanized txheej yuav tsim zinc vapor thaum lub vuam, dx54d zinc txheej muaj cov thooj tuab thiab tuab sib haum. Thaum siv nrog cov chaw siv hluav taws xob feem ntau yog cov tshuab hluav taws xob (nruab nrab}
Paintability: DX54D nto tuaj yeem ua ntej-}}}}}}} - passivation dawb) thiab roj. Nws qhov chaw mos roughness (feem ntau ra tsawg dua lossis sib npaug rau 1.6μm) yog ib nrab xim, thiab tsis zoo rau qhov chaw tsis zoo, ua rau tsis ncaj ncees, ua rau thaj chaw tsis sib xws tom qab pleev xim. Qhov no ua kom muaj kev sib txawv thiab cov nplaum ntawm cov txheej txheem hluav taws xob txuas ntxiv thiab cov topcoats, txo cov xim tsis zoo xws li sags thiab pinholes.
4.What yog tus nqi ua haujlwm ntawm DX54D Galvanized steel?
Piv rau stainless hlau (uas raug nqi 3 {{- 4-3 zaug ntau dua thiab tsis muaj cov kab mob khaub ncaws tshwj xeeb (welding)
Piv rau qis dua - qib galvanized steel (ntawm 5% {{{{{{9 {9 {9 {9 {tus nqi muag khoom), Kev muab cov nqi ntev ntev ntev.
5.Qhov dab tsi tseem ceeb ntawm DX54D hauv cov tsheb tsim khoom hauv tsheb?
Lub ntsiab lus ntawm DX54D tau txais txiaj ntsig zoo nyob hauv nws cov "ua kom tau raws li cov kev xav tau ntawm cov teeb meem ntawm cov teeb meem corrosion" - Yog li ntawd, nws tau dhau los ua cov khoom siv "cov khoom uas nyiam tshaj plaws xws li cov hnab paj hluav taws xob hauv kev lag luam, thiab siv dav hlau rau hauv kev lag luam tsheb thiab SUVs.
