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 raws li galvanized choj uas kub-dip galvanized, zoo li lub galvanized (hluav taws xob fribnized) thiab kub-dip galvanized (kub-dip galvanized);

Hlau thiab hlau xeb yooj yim hauv huab cua, dej lossis av, lossis txawm tias puas. Qhov pib txhua xyoo tshwm sim los ntawm corrosion account txog li 1/10 ntawm tag nrho cov hlau tso zis. Ntawm qhov tod tes, txhawm rau ua cov khoom lag luam steel thiab qhov chaw muaj tshwj xeeb ua kom zoo nkauj nyob rau tib lub sijhawm, yog li nws yog feem ntau kho nyob rau hauv txoj kev ntawm hluav taws xob galvanizing.

1.Priple:

Vim tias zinc tsis yooj yim hloov hauv cov huab cua qhuav, thiab hauv cov npoo av ntub, cov yeeb yaj kiab no tuaj yeem tiv thaiv sab hauv los ntawm corrosion. Thiab thaum cov txheej tau puas rau qee qhov laj thawj thiab cov hlau ua haujlwm tsis loj dhau, cov hlau matrix, kom cov hlau matrix ua tus Cathode thiab muaj kev tiv thaiv.

2. Kev ua txuj ci:

1) Zinc Txheej Tawv yog tuab, lub crystallization yog qhov zoo, hnav thiab tsis muaj qhov hws, thiab cov xeb tawm tsam yog qhov zoo;

2) Cov txheej zinc zinc tau los ntawm electroplating yog ntshiab thiab corrodes maj mam nyob rau hauv acid thiab alkali huab, uas tuaj yeem tiv thaiv cov hlau loj;

3) Zinc Txheej Tsim Tsim los ntawm Chromic acid passivation dawb, xim, tub rog ntsuab, zoo nkauj, muaj ib qho kev zoo nkauj;

4) Vim hais tias lub zinc txheej muaj qhov ua tau zoo, nws tuaj yeem txias, dov, khoov, khoov thiab lwm txoj kev ua kom muaj kev puas tsuaj.

3. Daim ntawv thov uas:

Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, electroplating kev lag luam cuam tshuam ntau thiab ntau cov teb. Tam sim no, daim ntawv thov ntawm galvanizing tau thoob plaws hauv kev tsim khoom thiab chaw tshawb fawb ntawm kev lag luam hauv tebchaws. Piv txwv, tshuab tsim, hluav taws xob kev tsim, tshuaj lom neeg kev lag luam, kev tsheb thauj khoom, affic zog, yog qhov tseem ceeb hauv kev lag luam hauv tebchaws.

Kub-DIP Galvanized Choj(kub-dip zinc choj)

1, Kub DIP Zinc Cov Lus Qhia:

Kub Dip Zinc yog ib qho ntawm cov txheej txheem zoo tshaj plaws rau kev tiv thaiv steel substrate. Nws yog nyob rau hauv lub xeev ua kua ntawm zinc, tom qab cov leeg ua rau lub cev thiab cov hlau ua kom huv si plinc txheej, tab sis kuj tseem tsim lub zinc - hlau alloy txheej. Txoj kev plating no tsis tsuas yog muaj cov yam ntxwv ntawm corrosion tsis kam ntawm galvanizing, tab sis kuj muaj zinc-lem txheej. Nws tseem muaj cov kev ua kom haum corrosion muaj zog uas tsis tuaj yeem piv nrog Galvanizing. Yog li ntawd, txoj kev plating no tshwj xeeb tshaj yog tsim nyog rau txhua hom acid, alkali huab thiab lwm yam muaj zog corrosion ib puag ncig.

2.Princ:

Kub DIP Zinc Txheej yog tsim nyob rau hauv peb kauj ruam hauv qab cov dej kub siab:

1) Cov hlau hlau hauv qab yog yaj los ntawm zinc daws kom tsim tau zinc-iron coey theem txheej;

2) Cov zinc ions hauv cov txheej alloy nyob rau hauv lub alloy txheej ntxiv diffuse rau lub matrix los ua ib qho zinc-hlau txheem;

3) Cov saum npoo ntawm alloy txheej qhia rau cov txheej zinc.

3. Kev ua txuj ci:

(1) nrog tuab tuab ntshiab zinc txheej npog cov npoo ntawm cov hlau, nws tuaj yeem zam cov hlau sib tiv thaiv, tiv thaiv cov hlau matrix ntawm corrosion. Nyob rau hauv cov huab cua dav dav, cov npoo ntawm zinc txheej ib qho nyias nyias thiab tuab rau yaj hauv dej, yog li nws ua lub luag haujlwm tiv thaiv ntawm cov hlau matrix. Yog zinc oxide thiab lwm yam kev sib xyaw ua ke hauv cov cua los ua cov ntsev tsis muaj ntsev, corrosion tiv thaiv yog qhov zoo tagnrho.

(2) Nws muaj hlau - zinc alloy txheej, hauv cov nkoj hiav txwv ntsev txau thiab muaj cua kev lag luam kev ua haujlwm txawv corrosion;

(3) Vim tias cov lag luam ua ke, Zinc-hlau sib txawv, nrog cov ris muaj zog tiv taus;

(4) Vim tias Zinc muaj cov txheej txheem zoo, nws cov txheej hlau alloy

(5.

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

(7) Cov txheej dawb huv zinc yog cov txheej yas tshaj plaws hauv galvanized txheej, nws cov khoom yog nyob ze rau cov ntshiab zinc, ductility, yog li nws hloov tau yooj yim.

4. Daim ntawv thov uas:

Daim ntawv thov ntawm kub dip galvanizing nthuav nrog kev txhim kho kev lag luam thiab kev ua liaj ua teb. Yog li ntawd, kub-dip galvanized cov khoom hauv kev lag luam (xws li kev siv tshuaj choment, cov hlau thiab roj av, tau siv dav dav, thiab lwm yam. ntawm lawv cov tsos zoo nkauj thiab kev ua kom zoo corrosion.

Ob, qhov sib txawv ntawmtsuag chojthiabGalvanized choj

Cov choj txau thiab cov choj Galvanized tsuas yog sib txawv hauv cov txheej txheem, cov kev qhia tshwj xeeb, qauv, qauv thiab qauv ntawm tus choj zoo tib yam.

Tus txheej txheem sib txawv ntawm cov kab tsuag thiab cov choj galvanized:

Ua ntej tshaj plaws,Galvanized chojThiab cov choj yas txau rau cov hlau cable choj, lub ntsej muag yooj yim yog tias muaj cov tshuaj txau yas, thiab tsis tas yuav tsum muaj cov tshuaj txau yas, thiab tsis tas yuav muaj cov tshuaj txau yas
