Qib ntawm Galvanized Steel
Feb 26, 2024
Tso lus
Cov qib ntawm galvanized steel ntawv yog DX51D + Z, DX52D + Z, DC51D + Z, DC52D + Z, S350GD + Z, thiab lwm yam.galvanized steel ntawvlos yog steel phaj qib yog tsim los ntawm tsib ntu: cov khoom siv code, steel qib code, steel hom yam ntxwv, kub-dip galvanized code (D), +, thiab dav txheej txheej.
Piv txwv ntawm cov qib: DX51D Z (los yog ZF AZ), DC51D Z (los yog ZF AZ), DD52D Z (los yog ZF AZ) DX: Thawj tsab ntawv D txhais tau hais tias ca steel rau txias sib sau, thiab tsab ntawv thib ob yog X, Indicating tias lub xeev dov ntawm lub substrate tsis tau teev tseg; yog tias tsab ntawv thib ob yog C, lub substrate tau teev tseg raws li lub caij txias-kub substrate; yog tias tsab ntawv thib ob yog D, nws txhais tau hais tias lub substrate yog teev raws li ib tug kub dov substrate; 51 ~ 57: ob tug lej Qhia cov qib steel serial tooj; a D tom qab ob tus lej yog tus lej rau kub-dip galvanizing; Z qhia tias cov txheej yog zinc ntshiab, ZF qhia galvanized hlau alloy, thiab AZ qhia txog txhuas-zinc plating. Yog li ntawd:DX51D Zqhia tau hais tias cov khoom siv rau kev sib sau txias, tiaj tus hlau, lub xeev substrate tsis tau teev tseg, steel qib serial tooj yog 51, ntshiab zinc txheej, cov khoom kub-plated.
2. Piv txwv ntawm cov npe ntawm lwm cov qib galvanized
S350GD Z: S qhia cov qauv hlau, 350 qhia txog Min. yield zog yog 350Mpa, G qhia tias cov yam ntxwv steel tsis tau teev tseg, D qhia tias kub-dip galvanizing, thiab Z qhia tias txheej yog zinc.
HX340LAD ZF: qhia tau hais tias cov khoom siv rau txias sib sau high-strength ca steel, tsis tau qhia meej lub xeev ntawm substrate, Min. yield zog yog 340Mpa, steel hom yog high-strength low-alloy steel, zinc-hlau alloy txheej, kub-plated khoom.
HC340 / 590DPD Z: qhia tau hais tias cov khoom siv rau kev sib sau txias, siab zog ca steel, lub substrate yog teev raws li ib tug txias-dov substrate, Min. yield zog yog teev raws li 340Mpa, Min. tensile lub zog yog teev raws li 590Mpa, hom steel yog dual-theem steel, ntshiab kub-dip khoom nrog zinc txheej.
Code rau nto zoo
Ordinary nto: FA
Qib siab saum npoo: FB
Advanced Surface: FC
Txheej txheej kho
(1) Chromic acid passivation (C) thiab chromate-free passivation (C5): Qhov kev kho saum npoo no tuaj yeem txo cov xim dawb ntawm cov khoom thaum thauj thiab khaws cia. Thaum chromium-dawb passivation kev kho mob, tib neeg kev noj qab haus huv ntawm passive zaj duab xis squadron yuav tsum txwv tsis pub muaj teeb meem hexavalent chromium Cheebtsam;
(2) Chromic acid passivation Oil (CO) thiab chromium-free passivation Oil (CO5): Qhov kev kho saum npoo no tuaj yeem txo cov xeb dawb ntawm cov khoom siv thaum lub sijhawm thauj mus los thiab khaws cia.
(3) Phosphating (P) thiab phosphating Roj (PO): Qhov kev kho saum npoo no tuaj yeem txo cov xeb dawb ntawm cov khoom thaum lub sij hawm thauj mus los thiab khaws cia, thiab tuaj yeem txhim kho cov qauv ntawm cov hlau phaj.
(4) Fingerprint-resistant film (AF) thiab chrome-free fingerprint-resistant film (AF5): Kev kho saum npoo tuaj yeem txo cov xeb dawb ntawm cov khoom thaum thauj thiab khaws cia. Thaum tsis muaj chromium-dawb passivation kev kho mob, passivation zaj duab xis squadron yuav tsum txwv Hexavalent chromium muaj pes tsawg leeg.
(5) Kev kho roj txheej (O): txo cov cim ntawm xeb dawb thaum khaws cia thiab kev thauj mus los. Cov roj siv los tiv thaiv xeb feem ntau tsis yog siv los ua cov roj dov thiab stamping lubricant rau kev ua haujlwm tom ntej.
(6) Tsis muaj kev kho mob (U): Nyob rau hauv rooj plaub no, qhov saum npoo ntawm cov hlau phaj thiab steel siv yog qhov ua rau cov xeb dawb thiab cov pob dub thaum lub sij hawm thauj mus los thiab khaws cia thiab kev thauj mus los, thiab cov neeg siv yuav tsum tau ceev faj thaum xaiv.
