American txheem h - Beachs xav tau cov kev kho kom tiv thaiv kev tiv thaiv corrosion los tiv thaiv corrosion, kev puas tsuaj ib puag ncig, txuas ntxiv lawv txoj kev pabcuam lub neej hauv ntau yam kev siv. Kev xaiv ntawm kev kho yog nyob ntawm ib puag ncig (nyob sab nraud (sab nraud)
Kub - dip galvanizing yog qhov kev kho mob tshaj plaws rau sab nraum zoov lossis siab {1} noo noo noo noo. Cov txheej txheem cuam tshuam nrog h {{3} Tsov ci zinc (sib haum metallurgical sib khi ntawm zinc thiab hlau. The resulting coating, typically 85-120 microns thick, consists of zinc-iron alloys that act as a sacrificial barrier-zinc corrodes preferentially, protecting the underlying steel.
Cov Ntawv Thov: Cov choj, kev tiv thaiv txoj kev loj, cov qauv vajtria (piers, docks). Piv txwv li, San Francisco - Alakland Bay Tus choj sib tw siv galvanized w27 × 178 kab teeb meem, nrog zinc cov tshuaj tsuag thiab huab.
LIFPANAN: {{50+ xyoo nyob hauv cov chaw nyob deb nroog, 20-30 xyoos hauv cov ntug hiav txwv lossis thaj chaw ntsev kom nrawm dua corrosion).
Advantages: Low maintenance (no repainting needed), uniform coverage even in complex areas (flange edges, web-flange junctions).
Cov tshuab tha xim tha xim tau dav rau cov ntawv thov vaj tse tsim vaj tse thiab sab hauv tsev, muab kev tiv thaiv ob qho tib si thiab kev tswj hwm kev zoo nkauj. Lawv feem ntau muaj ntawm peb txheej:
Primer: Zinc - rich nplua nuj epoxy (85-95% zinc cov ntsiab lus) rau kev tiv thaiv Cathodic, thov ntawm 4-6 mils (100-150 microns).
Nruab nrab tsho tiv no: epoxy lossis polyurethane los tsim cov thickness (6-10 mils), txhim kho tshuaj lom neeg tiv thaiv.
Topcoat: Acrylic lossis fluoropolymer (2-4 lab) rau UV tsis kam thiab xim khaws cia.
Daim Ntawv Thov: Lub tsev lag luam lag luam, chaw ntau pob, cov chaw lag luam. Lub Mercedes - benz chaw ua si hauv Atlanta siv cov xim sib tw, nrog kev cai nyiaj Topcoat sib txuam nrog pab pawg.
LIFPANGAN: 15 {-} 20 xyoo nyob sab hauv tsev, 10-15 xyoo sab nraum zoov (nrog rau kev sib tw ua si sab nraud).
Cov txiaj ntsig: Customizable cov xim, tau tshaj nrog cov kws kos duab kos duab, thiab kho kom yooj yim ntawm thaj chaw uas puas.
Weathering hlau (tus kheej - Presing) yog kev kho tshwj xeeb rau sab nraum zoov, qis {1} {} kev siv txij nkawm. Cov qib nyiam Astm A588 tsim cov txheej tuab, ua rau muaj xeb txheej ("patina") thaum raug cov dej noo thiab oxygen. No patina (muaj ntawm cov hlau oxides thiab alloying xws li tooj liab thiab chromium) block ntxiv oxygen ntxiv, nres corrosion.
Cov Kev Siv: Txuas hniav, duab puab, cov qauv sab nraum zoov. Lub Tuam Txhab Nyab Laj Vietton, DC, siv A588 w {4 4}} duab, nrog nws lub ntuj muaj xeb ua ib feem ntawm kev tsim qauv.
LIFPANAN: {75+} xyoo tsis muaj txheej, raws li patina tus kheej - kho cov khawb me me.
Cov txiaj ntsig zoo: tshem tawm cov xim pleev xim, tsim ib qho tshwj xeeb zoo nkauj, zoo tagnrho rau cov chaw nyob deb nroog lossis qis} Cov chaw ua paug.
Hmoov txheej yog ib qho txheej txheem ua tiav yooj yim haum rau sab hauv tsev lossis chaw nyob sab nraum zoov daim ntawv thov sab nraum zoov. Cov hmoov polymer yog electrostatically thov rau h {l}} nqaj (56-392℃(356
Cov ntawv thov: Retail fluctures, Warehouse Shelving, Hniav ntsiab. Ikea faib cov chaw siv hmoov -}}} Beams rau racking, nrog xiav topcoat tsis kam khawb ntawm pallet jacks.
LIFPANK: 10-100 xyoo nyob sab hauv tsev, 5-8 xyoos sab nraum zoov (yog tias tiv thaiv).
Cov txiaj ntsig zoo: Muaj Zog Durability, tsis muaj volatile organic compounds (vocs), ntau yam xim ntau.
Epoxy Txheej ci yog siv hauv ib puag ncig lossis kev tiv thaiv qhov tsis kam rau acids, cov kuab tshuaj, lossis roj yog qhov tseem ceeb. Lawv tau thov raws li ib txheej ib txheej (10-20 mils) lossis hauv kev sib xyaw nrog tus thawj pib, tsim cov kev txwv tsis zoo.
Cov Kev Siv: Cov khoom siv khib nyiab pov tseg, cov khoom lag luam chemical. Houston refinery siv epoxy - coated w12 × cov duab sab, nrog 30% sulfuric acid raug.
LIFPANK: 15-20 xyoos nyob rau hauv cov tswj ib puag ncig.
Cov txiaj ntsig zoo: Cov tshuaj zoo heev, daim ntawv cog lus zoo rau cov hlau, tuaj yeem thov hauv txheej tuab.
Zinc - Nickel plating yog qhov siab {{- nqaj hlau). A 5 {{{}}}}}}}}}}}}}}}}}}}}} 15 micron txheej ntawm alloy (10-15% npib tsis kam, feem ntau siv hauv kev siv tsheb lossis cov ntawv thov marine.
Cov ntawv thov: h {- nqaj nkhaus hauv cov nkoj nkoj hauv cov neeg caij nkoj mus rau cov neeg ntug dej hiav txwv.
LIFPANAN: {30+} xyoo hauv qab dej ib puag ncig thaum kaw nrog rau sab topcoat.
Cov kev xaiv ntawm cov nyiaj sib pab kho cov nqi kho mob, lifespan, thiab kev ua tau zoo. Piv txwv li, tus choj nyob hauv nroog yuav siv A588 huab cua dav hlau kom tsis txhob pleev xim, thaum ntug hiav txwv loj ntawm- dip galvanizing kom tiv taus cov tshuaj ntsev. Hauv cov tsev lag luam ua lag luam muaj ob qho kev tiv thaiv no thiab tsim qauv, ua kom muaj kev ua haujlwm Asmeskas nyob twj ywm ua haujlwm thiab pom kev zoo ib yam rau kaum xyoo.
