Cov yam ntxwv uas cuam tshuam rau lub thickness ntawm zinc steel grating txheej yog tsuas yog: cov hlau muaj pes tsawg leeg ntawm cov hlau grating, nto roughness ntawm steel grating, cov ntsiab lus thiab kev faib ntawm active yam silicon thiab phosphorus nyob rau hauv lub steel grating, lub sab hauv kev nyuaj siab ntawm steel grating, geometric qhov ntev ntawm steel grating workpiece, thiab kub-dip galvanizing txheej txheem ntawm steel grating. Tam sim no thoob ntiaj teb thiab Suav kub-dip galvanizing qauv yog muab faib ua ntu raws li lub thickness ntawm lub phaj. Qhov nruab nrab tuab thiab hauv zos thickness ntawm zinc txheej yuav tsum ncav cuag cov tuab tuab los txiav txim siab qhov kev tiv thaiv corrosion ntawm zinc txheej. Lub sij hawm yuav tsum tau ua kom tiav thermal equilibrium thiab zinc-hlau pauv equilibrium rau steel grating workpieces ntawm txawv thicknesses txawv, thiab lub thickness ntawm txheej tsim kuj txawv. Qhov nruab nrab txheej txheej thickness nyob rau hauv tus txheej txheem yog ib tug muaj ntau lawm kev tsim nqi raws li saum toj no-hais galvanizing mechanism, thiab lub zos thickness yog ib qho kev paub tus nqi yuav tsum tau coj mus rau hauv tus account lub uneven tis ntawm zinc txheej thickness thiab cov yuav tsum tau rau corrosion kuj ntawm lub txheej. Yog li ntawd, tus qauv ISO, American ASTM tus qauv, Japanese JS tus qauv thiab Suav tus qauv muaj qhov sib txawv me ntsis rau cov tuab ntawm zinc txheej, uas zoo sib xws. Raws li cov kev cai ntawm tus qauv kub-dip galvanizing GB B 13912-2002 ntawm Tuam Tshoj cov neeg koom pheej ntawm Tuam Tshoj. Cov txheej txheem zinc txheej rau kub-dip galvanized steel grating cov khoom yog raws li nram no: Rau kub-dip galvanized steel gratings nrog ib tug thickness ntau dua los yog sib npaug zos rau 6 hli, qhov nruab nrab zinc txheej thickness ntawm kub-dip galvanized steel grating yuav tsum ntau tshaj 85 microns, thiab lub zos thickness yuav tsum ntau tshaj 70 microns. Rau kub-dip galvanized steel gratings nrog lub thickness tsawg dua 6 hli thiab ntau dua 3 hli, qhov nruab nrab zinc txheej thickness ntawm kub-dip galvanized steel grating yuav tsum ntau tshaj 70 microns, thiab lub zos thickness yuav tsum ntau tshaj 55 microns. Rau kub-dip galvanized steel gratings nrog lub thickness tsawg dua 3 hli thiab ntau dua 1.5 hli, qhov nruab nrab zinc txheej thickness ntawm kub-dip galvanized steel grating yuav tsum ntau tshaj 55 microns, thiab lub zos thickness yuav tsum ntau tshaj 45 microns.
Lub luag haujlwm thiab cuam tshuam ntawm kub-dip galvanizing txheej thickness
Lub thickness ntawm kub-dip galvanized txheej ntawm cov hlau grating txiav txim siab los tiv thaiv corrosion ntawm steel grating. Cov neeg siv tuaj yeem xaiv cov zinc txheej tuab uas siab dua lossis qis dua tus qauv. Nws yog qhov nyuaj kom tau txais cov txheej tuab dua hauv kev tsim cov hlau nyias nyias nrog cov npoo du tsawg dua 3 hli. Tsis tas li ntawd, zinc txheej thickness uas tsis yog proportional rau lub thickness ntawm steel grating phaj yuav cuam tshuam rau lub zog sib txuas ntawm cov txheej thiab substrate thiab cov tsos zoo ntawm txheej. Cov huab cua tuab heev yuav ua rau cov txheej txheej zoo li ntxhib thiab yooj yim rau tev tawm. Cov plated steel grating tsis tuaj yeem tiv thaiv kev sib tsoo thaum thauj thiab teeb tsa. Yog tias muaj cov khoom siv ntau dua silicon thiab phosphorus hauv cov khoom siv raw ntawm cov hlau grating, nws kuj yog qhov nyuaj heev kom tau txais cov txheej thinner hauv kev tsim khoom. Qhov no yog vim hais tias cov ntsiab lus ntawm silicon nyob rau hauv cov hlau cuam tshuam rau txoj kev loj hlob ntawm cov hlau txheej ntawm zinc thiab hlau, uas yuav ua rau lub (, theem zinc-hlau alloy txheej loj hlob sai heev thiab (mus rau saum npoo ntawm txheej, ua rau ib tug ntxhib thiab npub txheej nto, tsim ib tug grey txheej nrog tsis zoo adhesion. Yog li ntawd, raws li tau tham saum toj no, muaj uncertainty nyob rau hauv cov kev loj hlob ntawm cov galvanized txheej yog feem ntau uncertainty. ntawm txheej thickness nyob rau hauv qhov tseeb ntau lawm Lub thickness teev nyob rau hauv lub kub-dip galvanizing tus qauv rau steel grating yog ib tug empirical tus nqi generated tom qab ib tug loj tus naj npawb ntawm thwmsim, noj mus rau hauv tus account ntau yam thiab yuav tsum tau, thiab yog tsim nyog.
