1.How los xaiv zinc txheej rau cov chaw siv sib txawv?
Cov me nyuam muaj chaw muaj zog: xaiv 80 - 120g / m² (ib leeg (ib leeg-ib leeg-sided zinc coating tuab ntawm kwv yees li 5.6-8.4μm).
Muaj feem xyuam nrog cov xwm txheej: Cov khoom siv hauv tsev sab hauv tsev, cov rooj tog zaum hauv chaw tsim khoom), thiab cov chaw ua haujlwm hauv chaw ua haujlwm (xws li chaw ua haujlwm partitions (xws li chaw ua haujlwm partitions (xws li chaw ua haujlwm partitions (xws li chaw ua haujlwm plotitions (xws li chaw ua haujlwm plotitions (xws li cov chaw ua haujlwm plug (qab nthab).
Vim li cas: cov chaw ib puag ncig muaj cov noo noo thiab cov plua plav ntau ntau thiab zoo rau kev tshaj xov xwm corrosive. Zinc txheej tsuas yog yuav tsum muaj kev tiv thaiv yooj yim; Cov txheej tuab tuab yuav nce nqi ntxiv.
Moderately corrosive environments: Choose 120-180g/m² (single-sided zinc coating thickness of approximately 8.4-12.6μm).
Muaj feem xyuam nrog cov chaw nyob sab nraum zoov (xws li lub tsev phab ntsa thiab ru tsev nyob rau hauv tsis yog} cov khoom siv hauv chav ua noj), thiab thaj chaw qias neeg (xws li thaj chaw sab nrauv)).
Vim li cas: cov chaw ib puag ncig no yuav ntsib ib qho me me ntawm nag thiab av noo, raws li qee zaus plua plav. Ib nrab zinc coating sib npaug tiv thaiv thiab tus nqi, tiv thaiv zinc txheej los ntawm kev ua tiav tiav hauv lub sijhawm luv luv. Rau cov neeg muaj mob loj: Xaiv 180-275G / m² (kwv yees li 12.6-19.2μm zinc txheej ntawm ib sab), lossis siab dua.
Siv cov ntawv thov: zoo heev thiab thaj chaw ua haujlwm nyob ze ntawm cov nroj tsuag tshuaj lom neeg (xws li cov chaw nyob sab nraud (xws li cov chaw nyob sab nraud (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov (xws li cov thawv sab nraum zoov thiab cov thawv xa khoom).
Vim li cas: Hauv cov chaw ib puag ncig, tshuaj tsuag ntsev thiab acidic media tuaj yeem nrawm nrooj tab sis zinc txheej. Daim tuab zinc tuab tuab tuaj yeem txuas ntxiv rau "kev tiv thaiv kev tua tsiaj". Piv txwv li, hauv ntug hiav txwv ib puag ncig, 180g / m² zinc txheej tuaj yeem txuas nws lub neej tuaj yeem txuas nws lub neej los ntawm ntau dua 30% piv rau 120g / m² txheej.
2. Nws yuav tsum tsis txhob ua kom muaj kev ua kom zoo tshaj plaws ntawm zinc tuab thaum lub sijhawm ua tiav?
Rau cov txheej txheem ua (piv txwv li, kev sib sib zog nqus duab, ntau yam dabtsi yog khoov, lossis kev xaiv cov khoom siv zinc zoo li 120-180g / m² thiab zam 200g / m². Ntau dhau zinc txheej tuaj yeem ua rau brittle fracture thaum ua, tsis zoo cuam tshuam cov khoom lag luam zoo.
Rau kev ua tiav yooj yim (piv txwv li, shearing thiab dov, xws li corrugated sheet (txawm tias yog qhov siv tau, raws li kev ua haujlwm muaj tsawg kawg ntawm cov txheej xim zinc).
3. Nqi them tus nqi "nqi thiab lifespan", yuav ua li cas xaiv txoj cai zinc txheej?
Yog tias cov khoom lag luam yog npaj rau ntev - siv lub tsev muaj 20 xyoo lossis ntau dua}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}. Qhov no zam kev hloov chaw ntxov vim muaj xeb thiab yog tus nqi ntau dua.
Yog tias cov khoom lag luam yog npaj rau luv luv - tsis siv (piv txwv li, txawm tias siv sijhawm nyob sab nraud, ib qho 120-150g / m² txheej yog tau. Tsis muaj yuav tsum tau mus nrhiav kev ua zinc ntau dhau lawm; Tus nqi tswj yog qhov tseem ceeb dua.
4.Qhov kom sai li sai txiav txiav txim siab qhov tuab ntawm zinc txheej?
Ua ntej, txiav txim rau ib puag ncig: Puas yog ib puag ncig sab hauv (lub teeb corrosion), ib puag ncig corrosion (nruab nrab ntawm ntug dej), lossis ib puag ncig kev lag luam (hnyav corrosion)?
Tom ntej no, xav txog kev ua lag luam ua tiav: Yooj yim shearing lossis cov stample nyuaj?
Thaum kawg, txiav txim siab cov kavtiam: ntsuas "Zinc Txheej Thickness {{}} tus nqi,"}, 120-275g / m²).
5.Cov tuab ntawm cov txheej zinc zinc ntawm cov xim -}}} coated coil cuam tshuam nws lub neej?
Lub thickness ntawm zinc txheej ntawm cov xim -}}}} co coated balvanized chev ncaj qha cuam tshuam nws lub neej kev pabcuam. Qhov ob feem ntau yog "zoo correlated" {- Txoj Kev Tiv Thaiv Ib puag ncig Steel Substrate thiab lub sijhawm ntev dua lub neej ntawm cov khoom lag luam.
