Khoom Description
Galvanizing yog hais txog cov txheej txheem kev kho saum npoo uas daim hlau txheej txheej zinc rau saum npoo ntawm cov hlau, alloys lossis lwm yam khoom siv los ua lub luag haujlwm hauv kev zoo nkauj thiab tiv thaiv xeb. Txoj kev tseem ceeb siv yog kub -dip galvanizing.
Zinc yog yooj yim soluble nyob rau hauv acids thiab kuj yuav soluble nyob rau hauv alkalis, yog li nws yog hu ua amphoteric hlau. Zinc tsis tshua hloov hauv huab cua qhuav. Nyob rau hauv cov huab cua ntub, ib tug tuab yooj yim zinc carbonate zaj duab xis yog tsim nyob rau saum npoo ntawm zinc. Nyob rau hauv sulfur dioxide, hydrogen sulfide thiab marine atmospheres, zinc corrosion kuj tsis zoo, tshwj xeeb tshaj yog nyob rau hauv kub thiab high humidity uas muaj cov organic acids, zinc txheej yog yooj yim rau corroded.
DX53D Steel yog dab tsi?
DX53D yog ib qho qis- carbon, txias- ua hlau, feem ntau yog hlau nrog me me carbon thiab alloying ntsiab. Lub "DX" qhia nws cov duab kos-qib steel, "53" qhia ntau dua formability, thiab qhov thib ob "D" txhais tau tias nws kub -dip galvanized rau xeb kuj. Paub txog kev kos duab sib sib zog nqus, DX53D haum rau cov duab nyuaj thiab cov ntu tuab uas xav tau cov duab tuav thiab yoog raws. Sib npaug rau EN FeP05G thiab suav nrog 1.0951 hauv EU cov qauv, nws tau siv hauv tsheb, kev tsim kho, thiab tshuab.

Vim li cas thiaj xaiv peb DX53D steel?
Titanium (txog 0.30%):Qhov sib ntxiv ntawm titanium txhim kho qhov tsim ntawm DX53D thiab tiv thaiv kev loj hlob ntawm cov qoob loo, ua rau nws tsim nyog rau kev tsim cov txheej txheem sib sib zog nqus thiab sib sib zog nqus nqus cov txheej txheem, tso cai rau koj los tsim cov khoom siv ntau dua, tsim kom muaj txiaj ntsig zoo, thiab txo cov khoom seem.
Cov ntsiab lus nitrogen tsawg (tsawg dua lossis sib npaug rau 0.012%):Cov ntsiab lus nitrogen tsawg txo qis kev ntxhov siab thaum lub sij hawm tsim, txhim kho cov khoom ruaj khov, thiab ua kom zoo ib yam thaum lub sij hawm ua, tshwj xeeb tshaj yog rau cov ntawv thov uas muaj cov kev xav tau siab.
Tsawg carbon tsim (tsawg dua lossis sib npaug li 0.12%):Cov ntsiab lus tsis tshua muaj carbon tsub kom lub zog ntawm DX53D thiab txo cov brittleness, muab kev cuam tshuam zoo txawm tias nyob rau hauv cov hlau tuab, ua kom cov khoom ruaj khov nyob rau hauv ib puag ncig hnyav.
