Qhov sib txawv tseem ceeb ntawm galvanized thiab kub dip galvanized yog tias cov khoom siv galvanized feem ntau muaj qhov sib luag thiab ntse, qhov kub dipped galvanized cov qauv muaj qhov ntxhib tiav.
Galvanization yog txheej txheem ntawm kev tiv thaiv cov hlau nto ntawm corrosion. Tom qab ua tiav ntawm galvanization, peb hais tias qhov saum npoo yog "galvanized" yog tias nws ua tiav ntawm cov txheej txheem ib txwm ua. Txawm li cas los xij, yog tias peb siv txoj kev kub dipped, peb hu nws "kub dip galvanized nto".
Dab tsi yog Galvanized?
A galvanized nto yog hlau nto uas muaj zinc txheej rau kev tiv thaiv corrosion. Peb hu cov txheej txheem ntawm kev siv cov zinc txheej no "galvanization". Ntxiv mus, daim ntawv thov no ua tiav ntawm cov hlau lossis hlau.
Daim duab 01: Daim duab kos ntawm cov txheej txheem electroplating
Muaj ntau hom galvanization, suav nrog:
- Kub dip galvanization - immersion ntawm cov khoom hauv molten zinc
- Nruam galvanizing - ib daim ntawv ntawm kub dip galvanization, tab sis txoj kev no tsim ib txheej txheej zinc; Yog li, qhov kev tiv thaiv corrosion yog sib piv tsawg dua
- Cov tshuaj tsuag cua sov - txau ib nrab molten zinc rau ntawm cov khoom
- Electroplating - siv cov khoom thiab zinc hlau ua electrodes hauv electrochemical cell
- Mechanical plating - txoj kev tsis muaj hluav taws xob los tso cov txheej txheem siv hluav taws xob thiab cua sov
Kub Dip Galvanized yog dab tsi?
Kub dip galvanization yog txheej txheem ntawm txheej txheej zinc ntawm cov hlau txhawm rau tiv thaiv cov hlau ntawm corrosion. Peb tuaj yeem txhais nws li HDG. Cov txheej txheem no muaj peb kauj ruam loj, raws li hauv qab no:
- kev npaj nto
- Galvanizing
- Kev tshuaj xyuas
Nyob rau hauv cov kauj ruam npaj saum npoo, peb yuav tsum tau dai cov khoom hlau uas siv cov xov hlau los yog muab tso rau hauv ib lub khib nyiab. Tom qab ntawd, cov hlau mus los ntawm peb kauj ruam tu: degreasing, pickling thiab fluxing. Cov kauj ruam degreasing tshem tawm cov av ntawm cov hlau nto. Pickling kauj ruam tshem tawm zeb nplai thiab hlau oxide. Tom qab hauv cov kauj ruam fluxing, nws tshem tawm lwm cov oxides uas muaj nyob rau ntawm cov hlau nto thiab tsim cov txheej txheem tiv thaiv uas tuaj yeem zam tsis tau cov oxide ntxiv.
Daim duab 02: Txheej Txheem Kub Dip Galvanizing
Thaum lub sijhawm txheej txheem galvanizing, peb yuav tsum tau muab cov hlau tso rau hauv ib da dej ntawm zinc, uas muaj tsawg kawg yog 98% zinc. Ntawm no, cov hlau nyob rau hauv steel nto yuav tsim ib tug series ntawm zinc-hlau intermetallic txheej thiab ib txheej txheej ntawm ntshiab zinc. Hauv kauj ruam ntawm kev tshuaj xyuas, peb yuav tsum tau tshuaj xyuas cov txheej txheem. Ntxiv mus, peb yuav tsum txiav txim siab qhov zoo ntawm zinc txheej txheej.
Qhov txawv ntawm Galvanized thiab Kub Dip Galvanized yog dab tsi?
Kub dip galvanizing yog hom galvanizing. Qhov sib txawv tseem ceeb ntawm galvanized thiab kub dip galvanized yog tias cov khoom siv galvanized muaj qhov sib luag thiab ntse, qhov kub sip galvanized cov qauv muaj qhov ntxhib tiav. Tsis tas li ntawd, cov txheej txheem ntawm galvanizing suav nrog kev tsim cov zinc txheej rau kev tiv thaiv cov hlau los ntawm corrosion thaum kub dip galvanization suav nrog kev tsim cov zinc txheej ntshiab ntawm cov hlau los ntawm kev npaj nto, galvanizing thiab tshuaj xyuas.
Summary – Galvanized vs Kub Dip Galvanized
Hauv luv luv, kub dip galvanizing yog hom galvanizing. Qhov sib txawv tseem ceeb ntawm galvanized thiab kub dip galvanized yog cov khoom siv galvanized muaj qhov sib luag thiab ntse, qhov kub dipped galvanized qauv muaj qhov ntxhib tiav.
