{{0 {}} Dab tsi yog qhov tseem ceeb rau kev cuam tshuam tsis zoo?
Zinc muaj qhov cub npau npau tsawg (907 degree) ◦ zinc vaporizes sai ntawm high vuam (> 1000 degree), ua rau:
Tau muab pov tseg ntxiv: Zinc Vapor zom los ntawm cov hlau molten, ua cov spark spark;
→ Porosity Disfab tshwm sim: Vapor yog cuab nyob rau hauv Weld los ua pores (tshwj xeeb liner vuam);
→ Tsis khov Vuam: ARC / Kuj Vuam cov txheej txheem compressuting .
Qhov sib txawv hauv cov txheej zinc uas cuam tshuam ures kev tawm tsam yog qis dua li ntawd ntawm cov hlau substrate {{0} Tam sim no yog qhov yuav tsum tau ua ib qho zoo nugget.
Electrode electrode ◦ zinc reacts nrog daim ntawv tooj liab tooj liab los ua tooj dag alloy (zn-cu), ua rau:
→ Electrode Adhesion: Lub Zinc Txheej Adheres rau cov chaw hluav taws xob;
→ Hais kom luv hluav taws xob lub neej: Lub neej ntawm cov electrodes ib txwm yog txo rau 1/3 ~ 1/5 ntawm qhov uas ntawm zinc-dawb {}}
2. Kuv tuaj yeem xaiv hom galvanizing los ua kom zoo rau wardability?
Ua ntej electrogalvanizing (piv txwv): nyias zinc txheej (5 ~ 10μμm) poob zoo li qub kab ke .
Cov ntawv thov raug: Sab Nrauv npog xws li lub qhov rooj thiab hoods .
Galvanizing (GA) Puas yog qhov kev xaiv sib npaug
Cov ntawv thov raug: ntu xws li lub cev ntas thiab cov plag tsev uas xav tau ob leeg ua kom tsis kam thiab vuam .
Zam kev tuab-dip galvanizing (HDG) rau precision vuam
Nws tsuas yog pom zoo rau qhov tsis pom zoo (xws li chassis seem), thiab nruj kev tswj cov txheej txheem yog xav tau thaum vuam .
3. Dab tsi yog "txoj kev ruam" rau kev txhim kho galvanized ntawv vuam?
Kev xaiv cov khoom thiab sib txuam thiab txuam: piv txwv li rau cov khoom pom / qhov chaw pom vuam, GA rau cov txheej txheem kev siv HDG hauv thaj chaw siab-precision vuam thaj chaw;
Cov cuab yeej hloov kho tshiab: Zinc-resistant electrode + Dynamic Parameter tswj system;
Cov txheej txheem kev yoog raws: nce siab / tam sim no, ob chav pulte pulding, khaws cia tso pa;
Kev Kho Mob Hauv Zos: Laser ntxuav ntawm vuam chaw (tus nqi ntau dua tab sis tseem ceeb nyhuv).
4. Txoj kev sib tw thiab kev tawm tsam tshwj xeeb li cas rau cov tsheb loj?
Roj teeb ntim VUAM:
Qhov Teeb Meem: DaJimilar Hlau Vuam ntawm Galvanized Steel thiab Aluminium Plhaub (nquag los tsim cov xeeb Zn-Al Alloy); Kev daws: Siv kev sib txhuam vuam (FSW) lossis ultrasonic high}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} .
5. Cov kev lag luam kev lag luam zoo tshaj plaws thiab kev daws teeb meem tshiab?
Tshuab hluav taws xob ua haujlwm tshiab: Dispersion-Tshab-txhawb tooj liab electrode (xws li Cu-ZR): Lub neej yog 3 zaug ntev dua li cov tshuaj electrodes ib txwm; Composite coating electrode: pluas plating nrog molybdenum (mo) lossis npib tsib) los tiv thaiv zinc diffusion {}}
Kev hloov kho ntse ntawm vuam qhov tsis haum: cov kev hloov kho ntawm lub sijhawm tam sim no los xyuas cov nyiaj tau los ntawm cov nyhuv shunt ntawm zinc txheej; Kev yoog tau siab tswj: Rynamic kev nce ntawm electrode siab raws li cov txheej tuab raws li cov txheej zinc (xws li piv txwv li HDG: 400kgf).
Cov khoom siv pretreatment ◦ laser tu: ib nrab ntawm cov txheej zinc ua ntej vuam (qhov tseeb ± 0}} 5 hli); Ua cov txheej txheej: tshuaj txau muab tshuaj txhuam rau ntawm cov cam cov cheeb tsam kom txo rau shunt.
