Zinc paj sawv cev rau saum npoo morphology yam ntxwv ntawm kub-dip ntshiab zinc-coated kauj. Thaum steel sawb hla lub lauj kaub zinc, nws nto yog coated nrog molten zinc. Thaum lub sij hawm ntuj solidification ntawm zinc txheej no, nucleation thiab kev loj hlob ntawm zinc crystals tshwm sim nyob rau hauv tsim ntawm zinc paj.
Lo lus "zinc Bloom" pib los ntawm cov zinc ua tiav uas nthuav tawm cov paj zoo li cov paj ntoo. Qhov zoo tshaj plaws zinc siv lead ua qauv zoo ib yam li cov snowflake lossis hexagonal hnub qub. Yog li ntawd, zinc crystals tsim los ntawm solidification ntawm lub strip nto thaum lub sij hawm kub-dip galvanizing yog feem ntau yuav txais ib tug snowflake los yog hexagonal hnub qub qauv.
Galvanized steel kauj yog hais txog cov ntawv hlau kho los ntawm cov txheej txheem kub-dip galvanizing lossis electrogalvanizing txheej txheem, feem ntau muab rau hauv daim ntawv coil. Cov txheej txheem galvanizing cuam tshuam nrog kev sib koom ua ke molten zinc rau cov hlau kauj los txhim kho nws cov kev tiv thaiv corrosion thiab txuas ntxiv nws lub neej kev pab cuam. Cov khoom no pom kev siv dav hauv kev tsim kho, khoom siv hauv tsev, tsheb, tshuab, thiab lwm yam haujlwm. Nws zoo heev corrosion kuj, lub zog, thiab workability ua rau nws tshwj xeeb tshaj yog haum rau sab nraum zoov los yog ib puag ncig ntub.
Cov yam ntxwv tseem ceeb ntawmgalvanized steel kaujsuav nrog:
1. Corrosion Resistance: zinc txheej tiv thaiv cov hlau hauv qab ntawm oxidation thiab corrosion.
2. Kev ua haujlwm: tuaj yeem txiav, khoov, welded, thiab ua tiav.
3. Lub zog: Lub zog siab thiab lub zog ua kom nws tuaj yeem tiv taus qee yam kev ntxhov siab thiab kev thauj khoom.
4. Nto tiav: Smooth nto haum rau tha xim thiab txau.
Flowered galvanizing yog hais txog lub ntuj tsim ntawm zinc paj nyob rau saum npoo thaum zinc condensation raws li tus qauv. Flowerless galvanizing, txawm li cas los xij, yuav tsum tau tswj cov qib txhuas nyob rau hauv cov kev txwv tshwj xeeb lossis siv cov kev kho mob tshwj xeeb tom qab nws tawm hauv lub lauj kaub zinc kom ua tiav paj tsis tiav. Thaum ntxov kub-dip galvanized khoom inevitably featured zinc paj vim impurities nyob rau hauv zinc da dej. Yog li ntawd, zinc paj tau ib txwm txuam nrog kub-dip galvanizing. Nrog rau kev nce qib ntawm kev lag luam tsheb, zinc paj tau teeb meem rau cov txheej txheem ntawm cov ntawv kub-dip galvanized automotive. Tom qab ntawd, los ntawm kev txo cov ntsiab lus txhuas hauv zinc ingots thiab molten zinc mus rau qib kaum ntawm ppm (ib feem ntawm lab), peb ua tiav cov khoom lag luam uas tsis muaj lossis tsawg kawg zinc paj.
