Kub-dip galvanized steel yeeb nkab yog cov khoom siv hauv tsev uas muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, hnav tsis kam, thiab lub neej ntev. Yog li, yuav ua li cas yog kub-dip galvanized steel kav?

1. Raw khoom npaj: Lub ntsiab raw khoom ntawm kub-dip galvanized steel yeeb nkab yog zoo tib yam carbon steel yeeb nkab. Thaum lub sij hawm tsim cov txheej txheem, koj yuav tsum xub xaiv cov khoom siv hlau tsim nyog thiab xyuas kom meej tias nws cov khoom ua tau raws li cov qauv tsim nyog.

2. Cov yeeb nkab steel pretreatment: Ua ntej kub-dip galvanizing, cov yeeb nkab steel yuav tsum tau mus dhau ntawm cov txheej txheem pretreatment. Ua ntej, cov yeeb nkab steel yog pickled, thiab xeb raug tshem tawm kom tshem tawm oxides, roj, thiab lwm yam impurities ntawm qhov chaw. Tom qab ntawd, ntxuav cov yeeb nkab steel kom huv si. Qhov no yuav npaj koj rau cov txheej txheem galvanizing tom ntej.

3. Galvanizing txheej txheem: Kub-dip galvanizing yog txheej txheem uas cov kav hlau tau muab tso rau hauv cov kua zinc molten los tsim cov zinc txheej rau ntawm qhov chaw. Cov txheej txheem tshwj xeeb galvanizing suav nrog cov kauj ruam hauv qab no:
ib. Pickling: Cov yeeb nkab steel pretreated yog raus hauv cov kua qaub rau kev kho mob kom tshem tawm oxides thiab impurities ntawm qhov chaw. Cov kauj ruam no pab txhim kho qhov adhesion ntawm galvanized txheej rau saum npoo ntawm cov yeeb nkab steel.
b. Soaking: Raus dej cov yeeb nkab steel rau hauv preheated ammonium chloride tov. Cov kauj ruam no pab tshem tawm cov oxides los ntawm qhov chaw ntawm cov yeeb nkab steel thiab muab lub hauv paus zoo rau tom qab galvanizing.
c. Kev ziab: Tshem cov yeeb nkab uas ntub dej los ntawm kev daws thiab ziab kom tshem tawm cov dej noo ntawm qhov chaw.
d. Preheating: Xa cov yeeb nkab steel qhuav rau hauv qhov cub preheating rau preheating kev kho mob. Kev tswj ntawm preheating kub yog qhov tseem ceeb rau cov nyhuv galvanizing tom ntej.
e. Galvanizing: Dip cov yeeb nkab steel preheated rau hauv cov kua zinc molten. Hauv cov kua zinc, cov hlau ntawm cov yeeb nkab steel reacts nrog zinc los ua zinc-hlau alloy txheej. Cov kauj ruam no yuav tsum tau tswj lub sijhawm galvanizing thiab qhov kub thiab txias kom ntseeg tau tias qhov sib xws thiab qhov zoo ntawm cov txheej.
f. Txias: Cov yeeb nkab steel galvanized yog tshem tawm ntawm cov kua zinc thiab txias. Lub hom phiaj ntawm kev ua kom txias yog txhawm rau txhim kho cov txheej txheem thiab txhim kho nws cov adhesion.

4. Kev tshuaj xyuas thiab ntim khoom: Galvanized steel kav yuav tsum tau kuaj xyuas kom ntseeg tau tias lawv cov khoom ua tau raws li cov qauv tsim nyog. Cov ntsiab lus tshuaj xyuas suav nrog cov tsos zoo, txheej tuab, adhesion, thiab lwm yam. Cov kav hlau uas tsim nyog yuav raug ntim los tiv thaiv kev puas tsuaj thaum thauj thiab siv.

Kev tsim cov txheej txheem ntawm kub-dip galvanized steel kav yog qhov nyuaj thiab yuav tsum tau ua ntau yam txheej txheem. Txawm li cas los xij, cov txheej txheem no tuaj yeem muab cov kav hlau steel nrog cov khoom zoo tiv thaiv corrosion thiab zoo nkauj tsos, ua rau lawv siv dav hauv kev tsim kho, tsheb thauj mus los, petrochemicals, thiab lwm yam.

Txhawm rau ua kom tiav, cov txheej txheem tsim khoom kub-dip galvanized steel kav suav nrog kev npaj cov khoom siv raw, steel yeeb nkab pretreatment, txheej txheem galvanizing, tshuaj xyuas, thiab ntim khoom. Los ntawm cov txheej txheem no, kub-dip galvanized steel kav nrog txhim khu kev qha zoo tuaj yeem tsim ua kom tau raws li qhov xav tau ntawm ntau yam haujlwm engineering. Kub-dip galvanized steel yeeb nkab tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb hauv kev tsim kho vim nws cov khoom zoo heev los tiv thaiv corrosion thiab zoo nkauj tsos. Hauv kev txhim kho yav tom ntej, nrog rau kev tsim kho tshiab ntxiv thiab kev txhim kho cov txheej txheem thev naus laus zis, cov txheej txheem tsim khoom ntawm cov kav dej kub-dip galvanized steel kav kuj tseem yuav raug txhim kho txuas ntxiv los muab cov kev daws teeb meem zoo dua rau kev siv hauv ntau thaj chaw.
