1.Qhov corrosion tsis kam ntawm cov xim coated steel coils manifest?
Tshuaj lom neeg tua neeg: Cov xim hlau npoo (xws li polyester thiab fluorocarbon) Tiv Thaiv Hlau los ntawm Kev Nyab Xeeb Kev Nyab Xeeb, Dej Nag, thiab Lwj, Tiv Thaiv Oxidation thiab xeb.
Acid thiab alkali ntsev txau tiv thaiv: nyob rau hauv high {{} cov av noo, txo qhov kev pheej hmoo ntawm cov xim puxing thiab substrate coling thiab substrate coling thiab substrate cuj. Haum rau kev siv hauv cov nroj tsuag tshuaj thiab cov xuab zeb xuab zeb, ntawm lwm qhov chaw.
2.How yog huab cua tsis kam ntawm cov xim coils?
UV-resistant: High-quality coatings (such as fluorocarbon coatings) contain UV-resistant additives, allowing them to withstand long-term exposure to direct sunlight without fading, chalking, or cracking, maintaining color stability and surface integrity.
Haum rau huab cua sov heev: nyob rau hauv ib puag ncig nrog kev hloov kho siab thiab tev muaj zog rau lub caij ntuj sov thiab tev muaj kev tsim nyog rau kev siv hluav taws xob (xws li lub tsev pheeb suab sab nraud (xws li rooto thiab phab ntsa).
3.Qhov yog dej noo thiab dej tsis kam ntawm cov xim coated coils?
Cov txheej muaj qhov ntom ntom ntom thiab tuaj yeem tiv thaiv kom noo los ntawm kev nkag mus rau hauv substrate. Txawm hais tias nyob rau hauv ib puag ncig noo thiab los nag ib puag ncig, nws tuaj yeem txo cov hlau corrosion los ntawm kev ua haujlwm noo thiab txuas ntxiv nws cov kev pabcuam lub neej.
4.What yog cov kab laij teb kev tiv thaiv kev tiv thaiv tshuab ntawm cov xim -} coated coils?
Thawj theem: Kev cais lub cev
Cov txheej ntom ntom muaj qhov porosity ntawm<0.1%, blocking H₂O/O₂/Cl⁻ permeation (water vapor transmission rate ≤1.0 g/m²/day).
Ob theem ntawm theem: Electrochemical tiv thaiv
Zinc muaj qhov qis dua electrode peev xwm (-0.76v) dua li hlau (-0.44v), ua yeeb yam raws li kev ua txhaum cai thiab corroding nyiam.
Qeb peb: Interfacial Tshuaj lom neeg
Lub Chromate Conversion Txheej (lossis chromium - beating bonds, txhim kho}
5.Qhov yog lub tswv yim rau kev cuam tshuam nrog ib puag ncig heev?
Siab UV Cheeb Tsam (Desells / Highlands)
Reflective txias: Siv qhov siab - refuces kom muaj ntau dua lossis sib npaug rau 0.82) txo cov laus sib luag ntawm 20 degree, qeeb polymer laus.
UV {{- tiv taus ntxiv: nano - Ti₂ / CEO₂ hais tawm cov duab UV los ntawm 40%.
High - noo noo noo chaw (PH <4.0 acid los nag)
Dual - Txheej Kev Tiv Thaiv:
Primer: Epoxy Resin (Acid Cuam Tshuam)
Poscoat: PVDF (corrosion resistant txheej)
Tsim qauv txheej txheem: txoj kab nqes ntau dua lossis sib npaug rau 10℃(acceler acid dej nag ntws).
Cov ntug dej hiav txwv ntawm cov dej hiav txwv Ntsej Muag (CLT> 100mg / m³)
Txheej Txheej Txiaj Ntsig: Zinc -} {}}} Magnesium (ZM) + txheej hnyav dua lossis sib npaug ntawm 120g / m².
Ntug Sealing: Siv zinc - chrome ci sealant (ntsev txau tiv taus cov chaw txiav.
