Q: Dab tsi ua ntej ua ntej ntawm kev ua raws li cov substrate yog qhov yuav tsum tau ua ntej galvanizing?
A: {{{{1.} Degreat thiab tu: Tshem tawm cov roj deg (alkaline tov);
2.} pickling thiab xeb nyob rau hauv hydrochloric acid los yog sulfuric acid los tshem tawm cov hlau oxide nplai;
3. Dej ntxuav thiab qhuav: zam cov kua qaub tsis sib thooj ntawm cov kua dej zinc;
4.} annealing (yeem): Annealing hauv kev txo cov cua kom tshem tawm cov txheej txheem kev ntxhov siab thiab txhim kho cov nplaum ntawm zinc txheej {}}
Q: Yuav ua li cas los xyuas kom qhov kev sib txuam ntawm cov txheej galvanized thaum lub txheej txheem tsim khoom?
A: Txhawm rau kom cov kev sib tw ntawm Galvanized txheej, cov kab ke tseem ceeb rau cov kab kev ruaj khov thiab kev kho kom haum rau cov pa xinc kom tsis txhob muaj qhov tsis xws luag xws li zinc nodules lossis streaks .
Q: Lub luag haujlwm ntawm annealing txheej txheem hauv galvanized chev ntau lawm?
A: {{1. Tshem tawm txoj haujlwm tawv:
Recrystallization annealing tuaj yeem tshem tawm sab hauv kev ntxhov siab ntawm cov khoom txias, thiab tsis txhob tawg lossis deformation thaum lub sij hawm galvanizing tom ntej.
2.} txhim kho cov nplaum ntawm zinc txheej:
Annaling hauv kev txo cov cua tshem tawm cov oxides, ua cov dej huv si kom ua tiav metallurgical sib txuas nrog lub substrate .
3.}}}}}}}}}}}}} Cov Khoom Siv Cov Khoom Siv Neeg Kho Mob:
Kev tswj qhov kub thiab txias thiab lub sijhawm tuaj yeem kho lub zog ntawm lub zog kom phim cov kev xav tau ntawm kev siv sib txawv .
Q: Dab tsi yog qhov sib txawv ntawm cov txheej txheem ntau lawm ntawm cov txheej txheem kub-dip galvanizing thiab electro-galvanizing?
A: {{1. txheej txheej tsim qauv
Kub-dip galvanizing: cov hlau yog raus rau hauv 450℃molten zinc kua rau ua tus metallurgically sib raug zoo txheej tuab txheej kub txheej.
Electrogalvanizing: Lub electrolyte yog hluav taws xob kom tso nyiaj zinc ions los ua ib qho tsis yog xim hlau tsis sib xws.
{{0 {}} Ntau lawm efficiency thiab tus nqi
Kub-dip galvanizing: ceev ceev, tus nqi qis, haum rau huab hwm coj ntau lawm .
Electrogalvanizing: qeeb ceev, muaj zog siv hluav taws xob, tab sis zoo dua precision .
3.} Cov Lus Cim Khoom
Kub-dip galvanizing: pom tseeb zinc paj, muaj zog corrosion tsis kam, haum rau sab nraum zoov cov qauv.
Electrogalvanizing: Uniform saum toj tsis muaj zinc paj, haum rau precision tsos qhov chaw (yuav tsum tau sib phim nrog kev pleev xim).
Qhov tseem ceeb sib txawv: kub-dip galvanizing kev cia siab rau kev kub nyhiab me me metallurgical, thiab electrochemical depies ntawm 66 2}}
Q: Dab tsi yog qhov cuam tshuam ntawm cov txheej txheem txias ntawm galvanized coils ntawm kev ua haujlwm ntawm cov khoom kawg?
A: Tus txheej txheem txias ntawm galvanized chev ncaj qha cuam tshuam rau peb qhov khoom loj ntawm cov khoom:
{{01. cov khoom siv tshuab: dej nrawm tuaj yeem txhim kho lub zog, thaum qeeb txias tuaj yeem txhim kho kev sib txawv;
2. zinc Txheej txheej txheem: tus nqi cua txias txiav txim siab cov tuab ntawm cov fe-zn alloy txheej;
3. npoo zoo: tsis sib luag tau yooj yim coj mus rau zinc paj ntawm cov sib txawv lossis sib txawv.
