1.What yog cov txheej txheem sib txawv ntawm ob?
Galvanized ntawv:
Substrate: Txias-rolled steel ntawv (hlau me).
Cov txheej: ib txheej ntawm zinc (lossis zinc alloy) yog kub-dip coated nyob rau ntawm "kev tiv thaiv me me" tiv thaiv kev ua haujlwm (zinc corrodes ua ntej hlau).
Hom Hom: Gi (kub-dip ntshiab zinc daim nyias nyias muaj ib qho me me ntawm txhuas, nrog ib qho zinc paj tsos.
GL (zinc-aluminium daim ntawv): zinc +: zinc +, magnesium - substrate coated chines (az
Cov txheej txheem: tshuaj hloov dua tshiab txheej (xws li kev kho cov chromium licomium: txhim kho cov nplaum ntawm substrate thiab txheej.
Primer: Epoxy cob, xeb-pov thawj, ntim substrate.
Topcoat: Cov txheej xim (polyester / silicon hloov polyester / fluorocarbon, thiab lwm yam) thiab huab cua tsis kam.
2.What yog qhov sib txawv hauv kev xeb tsis kam?
Galvanized Sheet: Lub zinc txheej tiv thaiv cov hlau hauv paus los ntawm kev txi anodes, tab sis cov steel puag yuav xeb tom qab lub zinc txheej tau noj. Qhov kev pabcuam lub neej yog luv luv nyob rau hauv cov av noo, acid los nag, thiab cov tshuaj ntsev thiab cov tshuaj ntsev.
Xim-txheej coils muab ob chav tiv thaiv:
Zinc Txheej txi ntshav los tiv thaiv corrosion (puag txheej)
Organic txheej lub cev cais cov xov xwm corrosive (txheej saum npoo av).
PVDF Topcoat tuaj yeem tiv thaiv cov ntsev tsuag tsuag rau ntau tshaj 1,000 lub neej, thiab nws lifespan yog 2-3 zaug ntev dua li cov ntawv galvanized.
3.Yog li cas yog qhov sib txawv ntawm ob qho ntawm kev ua tau zoo nkauj?
Galvanized Ntawv: Tsuas cov nyiaj txho, nrog zinc paj rau saum npoo (daim ntawv tsis muaj zinc yog smoother), tsis muaj xim xaiv, yooj yim tawm ntiv tes.
Xim Coated Chev: xim: tuaj yeem kho nrog ib tus lej Ral / pantone xim xim (xws li xim dawb, xiav, liab, imitation ntoo grain, thiab lwm yam). Nto: HEEV cov gloss / matte / kev ntxhib los mos (suede, embossed), zoo nkauj thiab hides khawb.
4.What yog qhov sib txawv ntawm cov huab cua tsis kam ntawm ob qho?
Galvanized Sheet: Cov txheej zinc txheej tig grey thiab tsaus nyob rau hauv Ultraviolet teeb, thiab oxidizes nrawm nrawm hauv kev kub siab.
Xim Coated Chev: Lub topcoat txiav txim siab qhov ua tau zoo.
PVDF: tsis tshua muaj zog rau ultraviolet teeb, 20-xyoo xim retention tus nqi> 90%, qhov kub tsis kam 120 degree.
HDP: Zoo UV Kuj, haum rau kev siv dav dav sab nraum zoov.
PE: Yooj yim rau hmoov thiab ploj mus, haum rau kev siv sab hauv.
5.Qhov dab tsi yog cov kev tsis to taub txog cov ntawv galvanized thiab galvanized coils?
Tsis muaj xim coils tsis xav tau galvanized substrates? "
Tsis ncaj ncees lawm! Cov xim xim-txheej coils yuav tsum cia siab rau galvanized (los yog galvanized) substrates tiv thaiv, txwv tsis pub cov steel puag yuav xeb sai sai tom qab txheej puas lawm.
"Muaj peev xwm galvanized ntawv hloov xim xim-txheej coils rau sab nrauv phab ntsa?"
Tsis pom zoo! Galvanized ntawv tsis muaj xim, nyhav yuav grey, thiab yog nquag rau "dawb xeb - tsis muaj kev tiv thaiv txheej.
"Xim-txheej coils yog yooj yim rau khawb dua li galvanized cov ntawv txheeb?"
→ ib nrab. PE txheej muaj qhov hnyav dua, tab sis PVDF / HDP txheej tuaj yeem ncav cuag lub hardness ntawm 2h (mem hluavtaws tawv), thiab nws cov hnav tsis kam yog daim ntawv galvanized.
