Dab tsi yog Coated Sawb Steel?

Dab tsi yogCoated Steel Sawb?

Coated steel sawb hais txog cov khoom siv sib xyaw nrog ib lossis ntau txheej ntawm cov organic, inorganic lossis hlau txheej siv rau saum npoo ntawm cov hlau steel sawb (feem ntau yog txias- dov los yog kub- dov qis- carbon steel) los txhim kho nws cov corrosion kuj, hnav tsis kam, cov khoom zoo nkauj lossis kev ua haujlwm tshwj xeeb (xws li conductivity, rwb thaiv tsev kub). Nws yog dav siv hauv kev tsim kho, khoom siv hauv tsev, tsheb, ntim khoom thiab lwm yam lag luam

Raws li cov txheej txheem sib txawv, nws tuaj yeem muab faib ua pawg hauv qab no:

Organic coated steel sawb
Cov ntaub ntawv txheej: polyester (PE), polyvinylidene fluoride (PVDF), epoxy resin (Epoxy), acrylic (Acrylic), thiab lwm yam.
Nta: cov xim nplua nuj, huab cua zoo, kev ntxhib los mos (xws li ntoo grain, pob zeb lis).
Tej kev siv:
Xim-coated panels (xim steel vuas, tsev ntaub thaiv phab ntsa)
Cov khoom siv hauv tsev (cov tub yees, tshuab ntxhua khaub ncaws)
Billboards, kho kom zoo nkauj sab hauv

Hlau coated steel sawb
Cov ntaub ntawv txheej: zinc (galvanized), aluminium (aluminized), zinc -aluminium alloy (Galvalume®), tin (tinned), thiab lwm yam.
Nta: corrosion kuj, zoo conductivity, ib nrab weldable.
Tej kev siv:
Galvanized steel sawb: cable armor, automotive qhov chaw
Aluminized steel sawb: tso cov kav dej, qhov kub thiab txias tiv taus qhov chaw
Tinned steel strip: ntim khoom noj (cov kaus poom, cov kaus poom)

Inorganic coated steel sawb
Cov ntaub ntawv txheej: porcelain enamel, ceramic txheej, thiab lwm yam.
Nta: kub tsis kam, tshuaj corrosion kuj, siab hardness.
Tej kev siv:
Qhov cub liner (enamel steel strip)
Cov khoom siv tshuaj tiv thaiv -corrosion hauv ob sab phlu
Kub kub chimney

Composite coated steel sawb
Txheej txheej: ntau- txheej txheej (xws li "galvanized + organic txheej" lossis "txhuas-zinc alloy + ntiv tes- tiv taus txheej").
Nta: zoo zuag qhia tag nrho kev ua tau zoo, xws li corrosion kuj + zoo nkauj tsos.
Tej kev siv:
High-paj vaj huam sib luag (PVDF coated aluminium-zinc panels)
Tsheb lub cev panels (galvanized + electrophoretic xim)
