1.What yog galvanized coil z275?
Z: Sawv rau kub-dip ntshiab zinc (galvanized).
275: Sawv rau tag nrho cov hnyav ntawm ob sab npoo ob sab ntawm 275 grams ib square Meter (G \/ M²). Qhov no yog ib qho nruab nrab-tuab zinc txheej specification uas tuaj yeem muab cov tshuaj tiv thaiv zoo, tab sis nws lub neej tseem tsuas yog txwv tsis pub dhau xws li muaj kuab paug loj thiab seaside.
2.Yog peb yuav tsum ua "ob qho ci ci thiab ob qho ci" ntawm z275 galvanized coils?
Kev Tiv Thaiv Kev Tiv Thaiv Txhim Kho: Txhawm rau txhim kho nws cov tshuaj tiv thaiv corrosion, xws li muaj kuab paug nyob rau hauv qhov chaw phem, muaj ntsev ntau ultraviolet rays).
Muab cov xim thiab muaj nuj nqi: Muab cov xim ntau ntau yam xim, xws li ntxuav tus kheej (antibacterial, huab cua siab, thiab lwm yam).
Txuas Kev Pab Cuam Lub Neej: Tus Txheej Txheem Txheej Txheem Tsim los ntawm "ob qho ci ci thiab ob qho ci" tuaj yeem muab kev tiv thaiv deb dhau ntawm lub galvanized txheej.
3.Yog li cas yog "ob lub tsho muaj plaub thiab ob qho ci" txheej txheem?
Thawj lub tsho tiv no (primer txheej): thov txheej txheej ntawm primer rau cov khoom ua ntej ua ntej galvanized nto.
Primer Function: Cov nplaum nplaum: Muab kev ua kom muaj zog tshaj plaws nrog lub galvanized substrate.
Yooj yim corrosion tiv thaiv: txhim khu cov kev tiv thaiv corrosion (tshwj xeeb tshaj yog kev tiv thaiv kev txiav thiab npoo).
Kev rho tawm barrier: Tiv thaiv cov hlau ions ntawm substrate los ntawm kev tsiv teb tsaws los cuam tshuam rau sab topcoat.
Cathodic kev tiv thaiv: qee qhov primers (xws li epoxy primers-inhibing-inhibiting phooj ywg chromium-dawb ib qho kev tiv thaiv yog siv) kom muab cov tshuaj tiv thaiv ntxig ntxiv.
Thawj CILING (Primer Kho): ◦ Tau dhau qhov pib kub ci (feem ntau yog nyob rau ntawm qhov kub txog li 200 degree {2} {2}} degree).
Lub hom phiaj yog tso cai rau cov cob qhia hauv phau pib hla kev sib txuas ntawm cov tshuaj tiv thaiv kev sib txuas, thiab tsim cov duab tawv, ntom xim tawv.
Lub tsho ntev thib ob (topcoat txheej): Siv lub topcoat ntawm cov txheej txheem cured txheej.
Topcoat Muaj nuj nqi: Qhov kawg tiv thaiv: muab cov txheej txheem sab nraud tiv thaiv (kev tawm tsam UV
Daim ntawv kho kom zoo nkauj zoo nkauj: muab ntau yam xim, cilars (zoo siab, matte, matte, thiab lwm yam) thiab kev ntxhib los mos.
Cov haujlwm tshwj xeeb: tuaj yeem muaj kev ntxuav qia, tshuaj tiv thaiv, tshuaj tua kab mob, rwb thaiv tsev kom sov thiab cov khoom txias)).
Thib ob ci (Topcoat Kho): lub phaj steel nrog to topcoat yog dhau los ntawm kev kub siab dua (qhov ntsuas kub zoo ib yam li lossis qis dua li qhov pib ua ntej). Lub topcoat yog kiag li kho tau los ua cov txheej txheem tiv thaiv kawg thiab hniav.
4.Qhov dab tsi yog qhov zoo ntawm lub tsho "Ob-lub tsho tiv no, ob-ci" txheej txheem?
Zoo dua txhua yam kev ua tau zoo: Primer thiab Topcoat txhua tus muaj lawv tus kheej cov haujlwm thiab kev faib tawm ntawm kev ua haujlwm, thiab lawv ua ib qho kev tiv thaiv kom tiav ntau dua. Prover ua kom muaj adsures thiab yooj yim tiv thaiv corrosion, thiab topcoat muab cov huab cua zoo tshaj plaws thiab kev zoo nkauj.
Muaj zog corrosion resistance: ob-txheej teeb meem txuas ntxiv qhov kev pabcuam lub neej ntawm ib puag ncig ntawm qhov chaw hnyav, tshwj xeeb tshaj yog qhov uas presters tuaj yeem muab kev tiv thaiv ntxiv.
Cov huab cua zoo dua tsis kam thiab cov xim ua kom muaj xim thiab huab cua zoo tshaj plaws (HDP huab cua zoo dua - ua rau muaj kev zoo nkauj, thiab ua kom muaj kev zoo nkauj ntev. Cov ntaub ntawv thov dav dav hloov tau: nws tuaj yeem ua tau raws li cov tsev xav tau ntau dua (xws li cov khoom siv hluav taws xob siab, tshav dav hlau, chaw ua haujlwm hauv tsev, thiab lwm yam.
5.How ua "ob-lub tsho tiv no thiab ob-ci" xim-coated phaj ntawm z275 substrate ua thaum siv nyob rau hauv ib puag ncig corrosive heev?
Galvanized Txheej (Z275): Kev Txom Nyem Kev Tiv Thaiv Anode (tshwj xeeb tshaj yog rau kev txiav thiab khawb).
Primer txheej: Txhim kho Adhesion, qhov yooj yim tiv thaiv corrosion, cov nyhuv sealing.
Topcoat txheej: huab cua zoo tsis kam, kho hniav, ntxiv kev tiv thaiv kev tiv thaiv ntxiv.
Cov qauv no ua rau nws txoj kev ua tau zoo nyob deb tshaj plaws rau cov pa roj av uas muaj kuab lom (Z275)
