Khoom Taw Qhia
Lub nkev qes dej yog nyob hauv ib lub xuab zeb zinc da dej kom ua raws li lub zinc-plated hlau ntawv mus rau qhov chaw. Tam sim no, nws tsuas yog tsim los ntawm kev sib nrauj galvanizing txheej txheem, uas yog, coiled steel sheet yog tujtaws raus hauv lub zinc-plated plating tank tsim ib daim ntawv lo galvanized steel; ib qho ntawv hlau alloyed galvanized. Cov ntawv hlau no yog tsim los ntawm kub dip, tab sis tam sim ntawd tom qab muab tawm, nws kub txog li 500 ° C los tsim ib qho kev xuab zeb txheej zinc thiab hlau. Qhov no cov yob galvanized tau zoo adhesion thiab weldability ntawm lub txheej.
Cov teeb meem thiab teeb meem
Qhov tseem ceeb: kev zas, khawb ua, cov zinc particle, cov npoo pos huab, cov cua riam phom, cov pa riam phom, cov khoom tawg, cov khoom siv puas tsuaj, kev lag luam tsis zoo, cov ntug dej, buckling, qhov sib txawv ntawm qhov txawv, Embossing, zinc layer thickness , yob ntawv luam, thiab lwm yam.
Lub ntsiab ua rau zinc layer detachment yog: oxidation, silicon compound, txias emulsified emulsion yog dhau lo av, NOF oxidizing cua thiab tiv thaiv roj nplej taw siab heev, cua-roj piv tsis tsim nyog, hydrogen ndlwg tsawg, cua sov aerobic infiltration , sawb hlau Qhov kub ntawm lub khob dej kub npau npau yog qhov tsawg, qhov siab ntawm RWP seem tsawg, qhov nqus ntawm qhov cub tawg yog tsawg, qhov kub ntawm NOF seem yog tsawg, cov roj tsis yog evaporated, aluminium ntsiab lus ntawm zinc kaub yog qhov tsawg, qhov ceev ntawm lub tsev yog ceev dhau, qhov txo qhov tsis txaus, thiab cov zinc kua qis. Lub sij hawm luv heev thiab lub plating yog tuab heev.
Dawb xeb thiab dub me ntsis yog tshwm sim los ntawm qhov tseeb tias tsaus nti raug tsim los ntawm oxidation ntawm dawb xeb.
Lub ntsiab ua rau dawb xeb yog:
(1) Txwv tsis pub tus kheej, tsis txaus lossis tsis tuaj yeem lim huam cov tuab tuab tuab;
(2) Lub nplaum tsis tau roj los yog cov seem nyob ntawm qhov chaw txawb;
(3) Cov nplaim ntawm cov seev cev muaj dej noo thaum coiling;
(4) Kev Tiv Thaiv Kev Xyaum Ua Tsis Taus Tag Nrho;
(5) txais ntub lossis los nag rau thaum caij tsheb thauj lossis ntim;
(6) Lub sijhawm khoom tiav sijhawm ntev dhau lawm;
(7) Daim ntawv xuas tes yog sib txuas nrog lossis muab khaws cia ua ke nrog lwm yam kev tawm dag zog xws li kua qaub thiab alkali.
Cov khoom tiav yog tso cai cia mus txog rau peb lub hlis hauv lub tsev qiv ntawv kom tsis txhob muaj oxidation ntev dua.
Cim npe nrov: galvanized hlau coil txias dov khoom rau vov, ua hauv Suav teb, manufacturers, lwm tus neeg
