Vim li cas cov paj zinc txawv ntawm cov kav dej nyias-walled thiab tuab-walled nyob rau hauv tib txoj kev thiab kev ua haujlwm?

Raws li zoo tib yam kub-dip galvanizing thiab txias txias, zinc paj tau ntawm nyias-walled thiab tuab-walled kav tom qab kub-dip galvanizing tsis zoo ib yam. Cov paj zinc ntawm lub qub yog loj dua, thaum cov nyob tom kawg yog me dua. Peb nkag siab tias qhov txias txias ntawm cov zinc molten ntawm cov yeeb nkab steel nto yog cuam tshuam rau phab ntsa thickness ntawm cov yeeb nkab steel substrate. Thaum kub-dip galvanizing feem ntau ua tiav siv "flux method," qhov kub ntawm cov yeeb nkab steel (150-230 degree) nkag mus rau zinc molten qis dua qhov kub ntawm cov zinc molten (470-510 degree ) . Yog li ntawd, cov kav dej nyias nyias nqus cov cua sov tsawg dua, thaum cov kav dej tuab-walled nqus cua sov ntau dua. Txawm li cas los xij, nyob rau hauv cov txheej txheem tib yam, tom qab cov kav hlau hlau tau muab tso rau hauv cov zinc molten, thaum qhov kub ntawm cov yeeb nkab nyias phab ntsa tau mus txog qhov sib xws ntawm sab hauv thiab sab nrauv, qhov nruab nrab ntawm cov yeeb nkab tuab phab ntsa kuj tseem nyob hauv qab. galvanizing kub ntawm qhov chaw. Yog li ntawd, ib zaug tshem tawm ntawm cov zinc molten, cov zinc molten ntawm cov yeeb nkab nyias-walled tsuas yog maj mam solidification vim huab cua txias, whereas zinc molten rau ntawm cov yeeb nkab tuab-walled, sib nrug los ntawm cua txias, kuj yuav tsum tau dissipate tshav kub ntawm lub qis kub ntawm cov yeeb nkab qhov chaw, uas accelerates lub solidification ntawm molten zinc. Yog li ntawd, maj mam txias nyias-walled yeeb nkab tsim cov paj zinc loj, thaum cov yeeb nkab tuab-walled nrog cov cua txias sai ua cov paj me me zinc.
