Dab tsi Qhov txawv Txawv Kub Dip Galvanized Yeeb Nkab Thiab Yeeb Txias Txias-galvanizing?

Kub-dip galvanized yeeb nkabthiab cov yeeb nkab galvanized muaj qhov sib txawv zoo hauv galvanizing. Qhov ntau npaum li cas ntawm qhov kub ntawm qhov kub galvanizing tsis tuaj yeem dhau me, thiab qhov tsawg kawg yog 50-60 g / m2 ntawm ob sab thiab mus txog 600 g / m2. Galvanized txheej ntawm cov yeeb nkab electrogalvanized tuaj yeem yog nyias heev, txog li 15g / m2, tab sis yog tias cov txheej ua tuab dua, cov kab ntau lawm nrawm qeeb heev, thiab nws tsis haum rau cov txheej txheem cov yam ntxwv ntawm chav tsev niaj hnub, thiab qhov siab tshaj plaws yog hais txog lO0g / m2. Vim tias qhov no, kev tsim cov kav hlau electrogalvanized muaj kev txwv ntau.

Kub-dip galvanized yeeb nkabthiab tshuab raj electro-galvanized yog qhov sib txawv hauv microstructure ntawm txheej. Muaj txheej txheej ntawm cov tshuaj txhuam me ntsis ntawm cov ntshiab zinc txheej ntawm covkub-dip galvanized kavthiab lub hauv paus ntawm txoj hlua steel. Thaum cov ntshiab zinc txheej tsim crystallized, feem ntau ntawm cov zinc tsim, thiab cov txheej yog xim thiab tsis ntxeem tau. Cov zinc atom ntawm txheej electroplated zinc txheej tsuas yog tso rau saum npoo ntawm txoj hlua steel, thiab txuas nrog rau saum npoo ntawm cov hlua steel los ntawm kev ua lub cev. Muaj ntau ntau cov qhov ziab kom qhuav, uas yooj yim ua rau pitting vim yog qhov nruab nrab corrosive, yog li cov ntawv kub-dip galvanized yog ntau dua li cov ntawv electro-galvanized. Ntau tiv taus corrosion.

Cov txheej txheem kho cua sov ntawm kub-dip galvanizing thiab electro-galvanized yeeb nkab kuj tseem muaj qhov sib txawv. Cov yeeb nkab kub-dip galvanized feem ntau yog ua los ntawm pawg thawj coj ua raws li cov khoom siv raw, thiab txuas ntxiv txuas ntxiv thiab kub-dip galvanized rau ntawm kab galvanizing, thiab cov hlau tsis xeb tau txias tom qab tau rhaub rau lub sijhawm luv. Yog li ntawd, lub zog thiab plasticity raug cuam tshuam rau qee yam, thiab qhov kev ntaus nrig yog qhov phem dua li ntawm tib lub txias txias-phaj tom qab ua kom tsis zoo thiab ua kom tsis haum ntawm cov kab ntau lawm. Lub tshuab hluav taws xob electrogalvanized yog ua los ntawm cov ntawv txias-txias, uas yog lub hauv paus tau lees tias cov kev ua tiav tib yam ntawm cov ntawv txias, tab sis nws cov txheej txheem nyuaj kuj nce tus nqi ntau lawm. Hauv qhov luv luv, kub-dip galvanized yeeb nkab muaj qis tus nqi tsim khoom thiab cov ntawv thov dav dua, thiab tau dhau los ua cov hom loj hauv cov yeeb nkab galvanized.

Kub-dip galvanizing corrosion tsis kam yog ntau dua li txias txias galvanizing (tseem hu ua electro-galvanizing). Kub-dip galvanizing tsis xeb hauv ob peb xyoos, thiab txias-galvanizing yuav xeb hauv peb lub hlis.

Cov txheej txheem txias galvanizing yog siv los tiv thaiv cov hlau los ntawm kev xeb. Rau lub hom phiaj no, ib txheej xim ntawm zinc muab tub lim, uas yog thov rau qhov chaw tiv thaiv los ntawm txhua txheej txheej txheej thiab ziab kom dhau los ua cov zinc filler txheej hauv txheej txheej kom qhuav. Muaj cov ntsiab lus ntawm zinc (txog 95%). Cov hlau galvanized nyob rau saum npoo nyob rau hauv qhov chaw txias txias, thaum kub-dip galvanizing yog galvanization ntawm cov nplaim ntawm cov yeeb nkab steel nyob rau hauv kub dip tej yam kev mob. Nws txoj kev nplaum no muaj zog heev thiab nws tsis yooj yim kom poob tawm. Txawm hais tias cov yeeb yaj kiab kub-dip galvanized kuj tseem xeb, Txawm li cas los xij, nyob rau lub sijhawm ntev, cov cuab yeej kev kho thiab kev nyiam huv tuaj yeem tau txais.

Qhov sib txawv ntawm cov khoom lag luam galvanized:
1) Ob qhov chaw sab hauv thiab sab nrauv ntawm lubkub-dip galvanized steel yeeb nkabyog galvanized, thaum lub txias-galvanized steel yeeb nkab tsuas yog galvanized rau sab nrauv phab ntsa.
2) Lub plating txias txheej yog yam thiab qhov tuab yog nyias heev; cov kub plating txheej yog tuab thiab lub thickness tsis zoo tib yam.
3) Cov tsos ntawm plating txias yog ci thiab xim ntawm kub plating yog tsaus.
4) Vim tias cov plating txias txheej yog nyias, cov tshuaj tiv thaiv corrosion tsis zoo; cov kub plating txheej yog ntau zaus lub sij hawm tuab dua li cov txias txias, thiab cov txheej txheem infiltrated yog tsim nrog lub hauv paus hlau, thiab kev txhim kho qhov corrosion yog qhov zoo.
5) Cov yeeb nkab txias-galvanized steel zoo li ua rau ci thiab smoother; qhov kub-dip galvanized steel nto tsis txias txias thiab ci, thiab saum npoo ntawm kub-dip galvanized steel yeeb nkab zoo li qee qhov tsis sib txig, thiab saum npoo tsis ci, tsis cuam tshuam.
