The difference between galvanized bridge and hot-dip galvanized bridge

Galvanized choj ncej:

Galvanized choj, tseem hu ua hluav taws xob galvanized choj; Feem ntau to taub li galvanized choj uas yog kub-dip galvanized choj, qhov tseeb, nws yog tsis ncaj ncees lawm, zoo li galvanized yeeb nkab, galvanized choj muab faib ua ob hom, namely, txias galvanized (hluav taws xob galvanized) thiab kub-dip galvanized (kub-dip galvanized). );

Hlau thiab hlau xeb yooj yim hauv huab cua, dej lossis av, lossis txawm tias puas tag. Txhua xyoo steel poob los ntawm kev xeb nyiaj rau li 1/10 ntawm tag nrho cov khoom siv hlau. Ntawm qhov tod tes, txhawm rau ua kom cov khoom siv hlau thiab cov khoom muaj qhov tshwj xeeb ntawm qhov chaw, thiab muab nws lub ntsej muag zoo nkauj nyob rau tib lub sijhawm, yog li nws feem ntau raug kho nyob rau hauv txoj kev ntawm hluav taws xob galvanizing.

1.Txoj cai:

Vim tias zinc tsis yooj yim rau kev hloov pauv hauv huab cua qhuav, thiab hauv huab cua ntub, qhov chaw tuaj yeem tsim cov zinc carbonate zaj duab xis tuab heev, zaj duab xis no tuaj yeem tiv thaiv sab hauv los ntawm corrosion. Thiab thaum cov txheej txheem puas vim qee yam thiab lub hauv paus hlau tsis loj heev, zinc thiab steel matrix tsim ib lub microbattery, kom cov hlau matrix dhau los ua cathode thiab tiv thaiv.

2. Cov yam ntxwv ua tau zoo:

1) Cov zinc txheej yog tuab, crystallization yog zoo, tsis muaj pores, thiab corrosion kuj zoo;

2) zinc txheej tau los ntawm electroplating yog ntshiab thiab corrodes maj mam nyob rau hauv cov kua qaub thiab alkali pos, uas muaj peev xwm tiv thaiv cov hlau matrix;

3) Zinc txheej tsim los ntawm chromic acid passivation dawb, xim, tub rog ntsuab, zoo nkauj, muaj qee yam zoo nkauj;

4) Vim tias cov zinc txheej muaj cov ductility zoo, nws tuaj yeem ua kom txias txias, dov, khoov thiab lwm yam kev sib sau yam tsis muaj kev puas tsuaj rau txheej.

3. Daim ntawv thov Scope:

Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, kev lag luam electroplating koom nrog ntau thiab ntau thaj chaw. Tam sim no, daim ntawv thov ntawm galvanizing tau nyob thoob plaws hauv cov chaw tsim khoom thiab kev tshawb fawb ntawm lub teb chaws kev lag luam. Piv txwv li, kev tsim tshuab, khoom siv hluav taws xob, cov cuab yeej precision, tshuaj lom neeg kev lag luam, kev lag luam teeb, kev thauj mus los, riam phom, aerospace, atomic zog, thiab lwm yam, yog qhov tseem ceeb hauv kev lag luam hauv lub tebchaws.

Kub-dip galvanized choj(kub-dip zinc choj)

1, kub dip zinc piav qhia:

Kub dip zinc yog ib qho ntawm cov txheej txheem zoo tshaj plaws los tiv thaiv steel substrate. Nws yog nyob rau hauv cov kua hauv lub xeev ntawm zinc, tom qab heev complex lub cev thiab tshuaj ua, tsis tsuas yog nyob rau hauv lub steel plating thicker ntshiab zinc txheej, tab sis kuj tsim ib tug zinc - hlau alloy txheej. Txoj kev plating no tsis tsuas yog muaj cov yam ntxwv ntawm corrosion kuj ntawm galvanizing, tab sis kuj muaj zinc-hlau alloy txheej. Nws kuj muaj zog corrosion kuj uas tsis tuaj yeem muab piv nrog galvanizing. Yog li ntawd, txoj kev plating no tshwj xeeb tshaj yog haum rau txhua yam muaj zog acid, alkali pos thiab lwm yam muaj zog corrosion ib puag ncig.

2. Txoj Cai:

Kub dip zinc txheej yog tsim nyob rau hauv peb kauj ruam nyob rau hauv kub kub kua:

1) Cov hlau puag saum npoo yog yaj los ntawm zinc tov los tsim cov zinc-hlau alloy theem txheej;

2) zinc ions nyob rau hauv cov hlau alloy ntxiv diffuse mus rau lub matrix los ua ib tug zinc-hlau miscible txheej;

3) Qhov saum npoo ntawm txheej txheej txheej txheej txheej zinc.

3. Cov yam ntxwv ua haujlwm:

(1) Nrog cov tuab tuab tuab ntshiab zinc txheej npog lub npoo ntawm cov hlau, nws tuaj yeem zam cov hlau matrix thiab kev tiv thaiv corrosion, tiv thaiv cov hlau matrix los ntawm corrosion. Nyob rau hauv cov huab cua dav dav, qhov saum npoo ntawm zinc txheej tsim ib txheej nyias thiab ntom zinc oxide txheej, nws nyuaj rau yaj hauv dej, yog li nws ua lub luag haujlwm tiv thaiv ntawm cov hlau matrix. Yog hais tias zinc oxide thiab lwm yam khoom nyob rau hauv cov huab cua tsim insoluble zinc ntsev, kev tiv thaiv corrosion yog zoo tagnrho.

(2) Muaj cov hlau - zinc alloy txheej, compact, nyob rau hauv Marine ntsev tsuag cua thiab muaj huab cua kev ua tau zoo corrosion kuj;

(3) Vim muaj kev sib txuam ruaj khov, zinc-hlau miscible, nrog kev hnav tsis kam;

(4) Vim tias zinc muaj qhov zoo ductility, nws cov txheej txheej alloy thiab steel puag ruaj khov, yog li cov khoom kub plating tuaj yeem ua rau txias stamping, dov, kos duab, khoov thiab lwm yam ntaub ntawv yam tsis muaj kev puas tsuaj rau txheej;

(5) Tom qab kub-dip galvanizing ntawm steel qauv qhov chaw, nws yog sib npaug rau ib qho kev kho annealing, uas tuaj yeem txhim kho cov khoom zoo ntawm cov hlau matrix, tshem tawm cov kev ntxhov siab thaum tsim thiab vuam ntawm cov hlau, thiab yog qhov zoo rau kev tig. ntawm steel structural qhov chaw.

(6) Qhov saum npoo ntawm cov khoom siv tom qab kub dip galvanizing yog ci thiab zoo nkauj.

(7) Ntshiab zinc txheej yog txheej yas feem ntau ntawm kub dip galvanized txheej, nws cov khoom yog nyob ze rau cov zinc ntshiab, ductility, yog li nws hloov tau.

4. Daim ntawv thov Scope:

Daim ntawv thov kub dip galvanizing nthuav dav nrog kev txhim kho kev lag luam thiab kev ua liaj ua teb. Yog li ntawd, cov khoom kub-dip galvanized hauv kev lag luam (xws li cov cuab yeej siv tshuaj, kev ua roj av, kev tshawb nrhiav Marine, cov qauv hlau, kev xa hluav taws xob, kev tsim nkoj, thiab lwm yam), kev ua liaj ua teb (xws li: irrigation, tsev cog khoom), kev tsim kho (xws li: dej thiab roj kis tau tus mob, hlau casing, scaffolding, vaj tse, txuas hniav, tsheb thauj mus los, thiab lwm yam, tau dav siv nyob rau hauv xyoo tas los no, kub-dip galvanized khoom yog ntau thiab ntau lug siv vim lawv zoo nkauj tsos thiab zoo corrosion kuj.

Ob, qhov sib txawv ntawmtshuaj tsuag chojthiabgalvanized choj

Txau choj thiab galvanized choj tsuas yog sib txawv hauv cov txheej txheem, cov kev qhia tshwj xeeb, qauv, cov duab thiab cov qauv ntawm tus choj yog tib yam.

Cov txheej txheem sib txawv ntawm cov tshuaj tsuag choj thiab galvanized choj:

Ua ntej tshaj plaws,galvanized chojthiab yas txau choj yog rau hlau cable choj, galvanized choj yog ua los ntawm galvanized steel phaj, galvanized phaj kuv ntseeg hais tias tsis muaj yuav tsum tau piav ntau dhau lawm, thiab cov yas txau choj yog siv los ua txheej txheem ntawm electrostatic txau txheej rau saum npoo. ntawm galvanized choj, yog li nws yog hu ua yas txau choj, yooj yim to taub yog hais tias cov yas txau choj yog lub upgrade version ntawm galvanized choj, corrosion kuj muaj zog.
