Kub-dip galvanizingyog ib qho txheej txheem uas cov khoom siv hlau los yog ib feem nrog lub ntsej muag huv yog immersed nyob rau hauv molten zinc tov, thiab ib txheej ntawm zinc hlau yog tsim nyob rau saum npoo los ntawm lub cev thiab tshuaj tiv thaiv ntawm lub interface.Kub-dip galvanizing, tseem hu ua kub-dip galvanizing thiab kub-dip galvanizing, yog ib txoj kev zoo hlau los tiv thaiv corrosion, uas yog tsuas yog siv rau saum npoo los tiv thaiv corrosion ntawm hlau qauv, chaw thiab cov ntaub ntawv nyob rau hauv ntau yam industries.Yog li dab tsi yog cov yam ntxwv ntawmKub-dip galvanized seamless steel yeeb nkab?

1. Grey thaj ua rau thaj ntawm ntau qhov sib txawv ntawm qhov chaw ntawm galvanized seamless steel yeeb nkab yog cov xim sib txawv ntawm galvanizing, uas yog ib qho teeb meem nyuaj hauv kev lag luam galvanizing tam sim no, feem ntau cuam tshuam rau cov kab lus uas muaj nyob hauv cov yeeb nkab steel nws tus kheej thiab cov khoom hauv zinc da dej.Cov stain tsis cuam tshuam rau kev tiv thaiv corrosion ntawm cov yeeb nkab steel, tsuas yog qhov sib txawv ntawm qhov tsos.

2. Muaj cov cim maj mam tsa cov cim rau ntawm qhov chaw ntawm txhua qhov galvanized seamless steel yeeb nkab, uas yog tag nrho cov zinc, uas yog tsim los ntawm txias thiab solidification ntawm zinc kua ntws los ntawm cov yeeb nkab phab ntsa tom qab lub galvanized seamless steel yeeb nkab raug tshem tawm ntawm lub zinc lauj.

4. Qee cov neeg siv khoom yuav siv cov zawj txuas hauv cov txheej txheem ntawm kev siv galvanized seamless steel yeeb nkab los nias zawj.Vim lub tuab zinc txheej ntawm kub-dip galvanized seamless steel yeeb nkab, nyob rau hauv qhov kev txiav txim ntawm kev puas tsuaj sab nraud quab yuam, ib feem ntawm galvanized txheej yuav tawg thiab tev tawm, uas tsis muaj dab tsi ua rau qhov zoo ntawm galvanized seamless steel yeeb nkab nws tus kheej. .

5. Qee cov neeg siv khoom yuav hnov ​​​​qab tias muaj cov kua daj daj ntawm cov yeeb nkab galvanized seamless steel (cov kua no hu ua passivation kua), uas tuaj yeem cuam tshuam cov hlau nto.Feem ntau siv rau kev kho tom qab plating ntawm galvanized, cadmium thiab lwm yam txheej.Lub hom phiaj yog los tsim ib lub xeev saum npoo ntawm cov txheej txheej uas tuaj yeem tiv thaiv cov tshuaj tiv thaiv ib txwm ntawm cov hlau, txhim kho nws cov kev tiv thaiv corrosion, thiab ua kom zoo nkauj ntawm cov khoom.Nws tuaj yeem txhim kho corrosion kuj ntawm cov yeeb nkab steel thiab ua kom lub neej ua haujlwm ntev.

Cov nyhuv tiv thaiv ntawm kub-dip galvanized txheej ntawm seamless steel yeeb nkab yog zoo dua li cov xim los yog yas txheej.Nyob rau hauv tus txheej txheem ntawm kub-dip galvanizing, zinc diffuses nrog cov hlau los tsim ib tug zinc-hlau intermetallic compound txheej txheej, uas yog, ib tug alloy txheej.Cov txheej txheej hlau yog metallurgically sib raug zoo rau cov hlau thiab zinc, uas muaj zog dua li kev sib raug zoo ntawm cov xim thiab cov hlau.Cov txheej kub-dip galvanized yog raug rau qhov chaw atmospheric thiab tsis poob rau ntau xyoo kom txog rau thaum nws yog kiag li corroded lawm.

Kub-dip galvanizing technology ntawmseamless steel yeeb nkabFeem ntau tuaj yeem muab faib ua dip plating thiab tshuab plating:

1. Dip plating.Txias nrog dej ncaj qha tom qab soaking.Qhov nruab nrab tuab ntawm zinc txheej yog ntau dua 70 microns, yog li tus nqi ntawm galvanizing yog siab, thiab cov zinc yog loj.Nyob rau hauv ib puag ncig atmospheric ib puag ncig rau ntau tshaj 50 xyoo, muaj qhov pom tseeb ntawm cov zinc ntws, thiab qhov ntev tshaj plaws seamless steel yeeb nkab tuaj yeem plated rau 16m.

2. Tshuab plating.Tom qab galvanizing, sab nraud yog tshuab thiab sab hauv yog txias.Qhov nruab nrab tuab ntawm zinc txheej yog ntau dua 30 microns, tus nqi qis, thiab zinc noj me me.Tom qab ntau tshaj 20 xyoo ntawm kev siv nyob rau hauv ib txwm atmospheric ib puag ncig, yuav luag tsis muaj kab ntawm zinc kua yuav pom tau.General tshuab zinc ntau lawm kab 6-9m.
