Qhov sib txawv tseem ceeb ntawm galvanizing thiab tinning yog galvanizing yog daim ntawv thov ntawm lub tsho nyias nyias ntawm zinc rau ntawm qhov chaw, qhov tinning yog daim ntawv thov ntawm txheej nyias nyias ntawm ib qho chaw.
Galvanizing thiab tinning yog cov txheej txheem kev lag luam uas tseem ceeb hauv kev tiv thaiv xeb tsim ntawm cov hlau. Galvanizing yog txheej txheem kev lag luam ntawm kev siv cov zinc txheej ntawm cov hlau saum npoo rau kev tiv thaiv corrosion, thaum tinning yog txheej txheem ntawm kev siv cov txheej nyias ntawm cov tin rau ntawm cov hlau.
Dab tsi yog Galvanizing?
Galvanizing yog txheej txheem kev lag luam ntawm kev siv cov zinc txheej ntawm cov hlau nto rau kev tiv thaiv corrosion. Peb hu cov txheej txheem ntawm kev siv cov zinc txheej no "galvanization". Tshwj xeeb, daim ntawv thov no yog tsim los ntawm cov hlau lossis hlau.
Muaj ntau hom galvanization, xws li:
- 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
Ntawm tsib hom no, kub dip galvanization yog txoj kev siv ntau tshaj plaws. Nws yog txheej txheem txheej txheej zinc txheej ntawm cov hlau txhawm rau tiv thaiv cov hlau los ntawm corrosion. Peb tuaj yeem txhais nws li HDG. Cov txheej txheem no muaj peb kauj ruam loj: kev npaj nto, galvanizing, thiab tshuaj xyuas.
Thaum lub sijhawm npaj cov txheej txheem saum npoo av, peb yuav tsum tau dai cov khoom hlau uas siv cov xov hlau los yog muab tso rau hauv ib qho khoom 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.
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.
Tinning yog dab tsi?
Tinning yog txheej txheem ntawm kev thov txheej nyias ntawm tin rau ntawm cov hlau. Feem ntau, hom txheej no yog ua los ntawm wrought hlau los yog hlau. Cov khoom tshwm sim ntawm cov txheej txheem tinning yog hu ua tinplate. Tsis tas li ntawd, lo lus no tau siv dav rau txheej txheej txheej ntawm cov hlau nrog solder ua ntej soldering.
Feem ntau, cov txheej txheem no muaj txiaj ntsig zoo los tiv thaiv xeb tsim ntawm cov hlau nto. Txawm li cas los xij, nws kuj tseem siv tau rau qhov kawg ntawm cov xov hlau uas muaj txiaj ntsig zoo li cov hluav taws xob hluav taws xob los tiv thaiv oxidation thiab ua kom lawv tsis txhob tawg los yog unraveling thaum cov conductors siv ntau yam hlau txuas xws li twist-ons. Niaj hnub no, feem ntau siv tinplate yog los tsim cov kaus poom.
Qhov txawv ntawm Galvanizing thiab Tinning yog dab tsi?
Galvanizing thiab tinning yog cov txheej txheem kev lag luam uas tseem ceeb hauv kev tiv thaiv xeb tsim ntawm cov hlau. Qhov sib txawv tseem ceeb ntawm galvanizing thiab tinning yog tias galvanizing yog daim ntawv thov ntawm lub tsho nyias nyias ntawm zinc ntawm ib qho chaw, qhov tinning yog daim ntawv thov ntawm txheej nyias nyias ntawm ib qho chaw. Ntxiv mus, galvanization cuam tshuam nrog txheej hlau lossis hlau qhov chaw thaum tinning feem ntau suav nrog cov ntawv hlau lossis hlau.
Cov ntaub ntawv hauv qab no-daim duab tabulates ib sab ntawm qhov sib txawv ntawm galvanizing thiab tinning.
Summary – Galvanizing vs Tinning
Galvanizing thiab tinning yog cov txheej txheem kev lag luam uas tseem ceeb hauv kev tiv thaiv xeb tsim ntawm cov hlau. Qhov sib txawv tseem ceeb ntawm galvanizing thiab tinning yog tias galvanizing yog daim ntawv thov ntawm lub tsho nyias nyias ntawm zinc ntawm ib qho chaw, qhov tinning yog daim ntawv thov ntawm txheej nyias nyias ntawm ib qho chaw.
