1. Cov kev tiv thaiv ceev ib ntus li cas?
Ntxuav cov chaw khawb
So cov cheeb tsam khawb thiab thaj tsam 5cm nyob ib puag ncig nrog cov ntaub ntub dej kom tshem tawm cov roj thiab plua plav (tsis txhob siv cov ntaub ntub dej!) {}
Thov cov neeg sawv cev passivation: Thov cov khoom siv zinc-raws li tus cwj mem (muaj chromate passivation tus neeg sawv cev) los ua yeeb yaj kiab ib ntus {}}
Los yog tshuaj tsuag ib txheej nyias nyias ntawm wd -40 rust inibitor (tsuas yog nyob rau hauv cov chaw qhuav hauv sab hauv).
2. Xaiv cov ntaub ntawv hloov kho tshiab?
Epoxy Zinc-nplua nuj Primer + Xim Txheej Topcoat: Cov tshuaj zoo tshaj plaws (rov kho cov qauv txheej thawj)
Ib feem ntawm cov xim zinc-muaj cov xim pleev xim: Yooj yim kho (zinc hmoov cov ntsiab lus siab dua lossis sib npaug rau 80%)
Ob-tivthaiv Polyurethane Elastic Xim: Muaj Kev Sib Koom Tes Loj (anti-deformation)
3. Qhov txheej txheem kev tsim kho cov txheej txheem rau kev kho kho tas li?
Kev kho deg: Siv P240 Sandpaper rau maj mam zom raws cov ntawv kos kom tshem tawm cov kab txuas nrog hluav taws xob kom tshem tawm cov kab txuas nrog rau kev sib tsoo (feathered etraps
Fawm kib (Epoxy Zinc-nplua nuj + Kev daws teeb meem Topcoat yog li cas: Cov yeeb yaj kiab ntub ntau dua los yog sib npaug ntawm thaj chaw zinc)
Topcoat txuam: Thov tus thawj daim phaj xim code rau customized txheej (xim txawv ΔE <1. 5).
Ntxiv dag zog ntawm ntug kev sib khi thiab siv cov polyurethane (dav 3mm) rau ntawm thaj chaw kho kom tiv thaiv kom tsis txhob muaj dej rau tom qab {}
4. Yuav ua li cas yog corrosion txuas ntxiv thaiv cov thev naus laus zis?
Electrochemical monitoring: Paste a corrosion indicator patch at the repair point (color change warning threshold: >5μa / cmo) .
Corrosion inhibitor injection: For deep scratches (>503μm), Txuag cov nyom corrosion inhibitor (VCI) nrog rab koob
5. Cov haujlwm txwv tsis pub muaj li cas?
Npog ncaj qha nrog cov xim zoo ib yam (rhuav tshem lub Cathalic tiv thaiv ntawm zinc)
Siv cov kua qaub huv huv (tshem tawm cov txheej passive)
Tsis quav ntsej sab nraub qaum kev soj ntsuam (cov dej ua hws yuav corrode los ntawm sab nraub qaum)
