1.What yog qhov pom zoo Zinc Txheej Thickness rau hauv thaj chaw muaj kuab paug qhuav / qis paug?
Pom zoo zinc coating tuab: 120 {}} 180g / ㎡ ntawm ob sab tuab ntawm li 17-25μm, txiav txim siab ib qho nruab nrab-hnyav zinc txheej).
Tub Ntxhais Logic:
Nyob rau hauv ib puag ncig zoo li no, qhov tsis muaj qhov tseem ceeb ntsev txau lossis kua qaub- rad tiv thaiv, tsuas yog qhov pib sab nraum zoov. Lub zinc txheej ntawm 120-180g / ㎡ tiv thaiv tiv thaiv nag thiab cov hmoov av muaj plua plav los ntawm nws qhov kev ua txhaum cai. Ua ke nrog cov txheej txheem sab nrauv phab ntsa ntawm cov fluorocarbon xim lossis polyester pleev xim), txheej muaj peev xwm ua tiav lub neej pabcuam ntawm 15-20 xyoo.
Tsis tas li ntawd, cov txheej dinc ntau (feem ntau yog cov haujlwm ruaj khov, xws li curved phab ntsa lauj kaub), thiab tsis tshua zoo nkauj rau cov nyom sab nrauv lossis tev thaum ua.
Cov Kev Siv Cov Ntawv Raug: Kab Hlau Ruav Cov Hlau thiab Sab Nraud Hniav Hnav (xws li ua ntej} Painted Fixed) rau cov vaj tse thiab chaw ua haujlwm hauv nroog.
2.What yog cov lus pom zoo uas tuab rau cov ntug dej hiav txwv / cov av noo?
Pom zoo Zinc Txheej Thickness: 200 {}}}}}}}}}} ㎡ ntawm ob sab tuab ntawm kwv yees li 28-38μm, suav hais tias muaj kev sib tw zinc hnyav).
Tub Ntxhais Logic:
Ntsev tshuaj tsuag (clj ions) hauv ntug hiav txwv ib puag ncig yog thawj corrosion rau galvanized steel. Ntsev txau Txau ceev cov tshuaj tua kab ntawm zinc txheej. Yog hais tias lub zinc txheej hnyav dhau (<200g/㎡), zinc depletion and substrate corrosion (manifested as bulging and paint peeling on the exterior wall panels) may occur within 3-5 years.
Ib qho hnyav {{{0} duty} Duty zinc txheej ntawm 200-275g / ㎡ tseem ceeb txuas rau zinc txheej kev ua voj voog. Txawm nyob rau hauv cov tshuaj tsuag ntsev, ua ke nrog cov txheej txheem tiv thaiv, qhov kev pabcuam lub neej tuaj yeem ncav cuag 20-25 xyoos.
NCO TSEG: Yog tias sab nrauv phab ntsa kev xav tau ntau zaus vuam (xws li spricing loj kab hlau sib ntaub), alloyed zinc txheej (ZF). (Nyob rau tib tuab, alloyed zinc txheej zoo nkauj nyob rau hauv ntug dej hiav txwv ntawm lub zos siab, sab nrauv phab ntsa nag dej ntws los pab los nag thaj chaw.
3.Qhov yog qhov pom zoo ZINC coating Thickness rau cov chaw lag luam muaj kuab paug?
Pom zoo Zinc Txheej Txheej: ntau dua lossis sib npaug ntawm ob sab (sib piv rau ib qho zinc (sib npaug
Tub Ntxhais Logic:
Acidic thiab alkaline mist (xws li ov thiab nox) hauv kev lag luam ncaj qha rau cov kua qaub huv si
Lub zinc tuab ntawm ntau dua los yog sib npaug rau 300g / ㎡ muab cov kev cawm kom txaus "rau qeeb corrosion. Nws yuav tsum tau ua ke nrog kev corrosion tshwj xeeb - Tsis muaj xim fluoride (xws li lub neej pabcuam tshaj 15 xyoos.
Ua cov kev ceev faj: tuab zinc Txheej txheej zinc Preheating (rau 60-80 degree) lossis xaiv ib qho "muag substrate" (txhawm rau txo cov txheej txheem hardness thiab txhim kho kev ua haujlwm tag nrho) yog pom zoo.
Cov Kev Siv Raug Cai: Sab nrauv phab ntsa Panels rau cov tsev nyob thiab sab nrauv sab nrauv studs rau cov tsev pej xeem rau cov nroj tsuag tshuaj lom neeg.
4.How yog zinc txheej qauv cuam tshuam rau lub sijhawm ntev-} lub sij hawm ruaj ruaj ntawm phab ntsa sab nrauv?
Cov ntawv sau nyiam suav nrog phab ntsa kom zoo nkauj (uas xav tau cov nyom nkhaus sib dhos (xws li snap - ntawm phab ntsa vaj huam). Ntshiab Zinc co co co coe
Cov kev xav tau suav nrog sab nrauv phab ntsa load - belded spreming (xws li sab nrauv phab ntsa txhawb ze cov yees txias). Alloyed Zinc Txheej txheem ua kom muaj zog ua rau lub substrate, tshem tawm zinc vuam thaum lub sijhawm kev co los ntawm kev co, tiv thaiv kom tsis txhob xeb, tiv thaiv kev xeb lossis kev sib xyaw ua ke.
5.Qhov twg yog cov laj thawj yog xaiv cov txheej zinc rau cold-} rolled steelized steel rau tsev sab nrauv phab ntsa?
Kawg zinc txheej tuab tuab tuab tuab i6}} Kev ua ib puag ncig corrosion (Core) + Tus Nqi Them Nqi (Nyiaj Txiag)
Thaj chaw qhuav dej qhuav: 120-180g / ㎡ (feem ntau (feem ntau cov ntshiab zinc txheej);
Nquag / siab {- Cov av noo noo: 200-275g / ㎡ (ntshiab Zinc Txheej, nrog alloying nyiam rau welded Cheebtsam);
Muaj cov thaj chaw muaj kuab paug: ntau dua lossis sib npaug nrog 300g / ㎡ (ntshiab zinc txheej yuav tsum tau preheating, lossis alloyed zinc txheej).
