1. Kev npaj khoom siv
Cov khoom siv raw ntawm galvanized steel coils yog cov hlau zoo tib yam, uas yog txiav, hauv av, leveled thiab longitudinally sheared kom tau cov nplooj ntawv tiaj tus ntawm qhov xav tau loj. Nyob rau hauv cov kauj ruam no, nws yog undoubtedly tseem ceeb heev los xyuas kom meej qhov seem ntawm cov hlau kauj thiab smoothness ntawm sheared npoo.
2. Kev kho deg
Ua ntej galvanizing, steel coils yuav tsum tau kho saum npoo. Ua ntej, nws yog acid-ntxuav nrog hydrochloric los yog sulfuric acid kom tshem tawm cov xeb thiab av. Tom qab ntawd, nws yog huv si yaug nrog dej thiab qhuav nrog compressed cua. Qhov no yog ua los xyuas kom meej tias cov galvanized txheej adheres ze rau ntawm steel nto, yog li txhim khu nws corrosion kuj.
3. Kub-dip galvanizing
Kub-dip galvanizing yog txheej txheem tseem ceeb hauv kev tsim cov galvanized steel coils. Cov txheej txheem steel kauj yog immersed nyob rau hauv ib tug galvanizing da dej qhov twg zinc molten npog rau saum npoo los tsim ib zinc alloy. Cov txheej txheem yog nqa tawm ntawm qhov kub thiab txias, feem ntau tswj ntawm 450 thiab 500 degree. Tsis tas li ntawd, lub thickness ntawm zinc txheej yuav tsum tau kho kom ua tau zoo corrosion kuj.
4. Cua txias thiab passivation
Tom qab kub-dip galvanizing, steel coils yog txias thiab passivated. Kev ua kom txias, uas tuaj yeem ua tiav los ntawm dej lossis cua txias, yog txhawm rau txo qhov kub ntawm lub kauj kom sai kom tsis txhob muaj kev cuam tshuam ntawm cov txheej txheem lossis kev ua haujlwm ntawm zinc txheej. Passivation, ntawm qhov tod tes, yog tsom rau kev txhim kho corrosion kuj ntawm zinc txheej thiab feem ntau yog siv rau saum npoo nrog chromium-based passivator.
Galvanized coilsfeem ntau yog siv rau hauv kev lag luam hauv qab no.
Ib tug loj tus naj npawb ntawm nyias galvanized coils yog siv nyob rau hauv automotive manufacturing, refrigerated ntim, kev tsim kho, qhov cua thiab cua sov chaw thiab cov rooj tog tsim. Galvanizing tau dhau los ua ib txoj hauv kev tseem ceeb ntawm kev tiv thaiv corrosion rau hlau thiab hlau, tsis yog vim zinc tsim cov txheej tiv thaiv ntom ntom ntawm cov hlau, tab sis kuj vim nws cov nyhuv cathodic, uas tiv thaiv corrosion ntawm cov khoom siv ferrous los ntawm kev tiv thaiv cathodic thaum galvanized txheej yog tawg.
Kev tsim kho kev lag luam: ru tsev, ru tsev Cheebtsam, sam thiaj yob, rooj, kiosks, warehouses, roller shutters, heaters, rainwater kav thiab hais txog.
Cov khoom siv hauv tsev: tub yees, tshuab ntxhua khaub ncaws, hloov pauv, cua txias, microwave ncu, toasters, tshuab luam ntawv, vending machine, hluav taws xob kiv cua, lub tshuab nqus tsev vacuum thiab lwm yam.
Kev lag luam rooj tog: teeb pom kev zoo, txee dai khaub ncaws, txee, txee, txee, kos npe, khoom siv kho mob thiab lwm yam.
Kev lag luam kev thauj mus los: nws pib dej hiav txwv qab nthab yob, tsheb plhaub compartment yob, tsheb laij teb, tsheb ciav hlau, ntim, phab ntsa loj, nkoj bulkhead yob, thiab lwm yam.
Lwm yam: cov khoom siv suab paj nruag plhaub pov tseg, daim ntawv tshaj tawm, moos thiab saib, cov khoom siv yees duab, meters, thiab lwm yam. Xim coated steel coil yog kub-dip galvanized coil, kub-aluminium-zinc plated coil, electro-galvanized kauj, thiab lwm yam. coil, tom qab qhov chaw ua ntej kev kho mob.
