Plating
Txheej thickness yog qhov tseem ceeb tshaj plaws guarantee rau corrosion kuj.Qhov loj ntawm txheej txheej, qhov zoo dua qhov kev tiv thaiv corrosion, uas tau raug pov thawj los ntawm ntau qhov kev ntsuam xyuas nrawm thiab kev kuaj qhov ntswg.
Raws li qhia hauv qab no:

Rau cov xim hlau daim hlau raws li (aluminium) zinc plated daim hlau, cov txheej tuab feem ntau cuam tshuam rau qhov kev ua haujlwm zoo ntawm cov xim hlau phaj.Lub thinner lub substrate, lub thicker lub zinc txheej, thiab qhov zoo dua corrosion kuj ntawm kev txiav.Tam sim no tau lees paub thoob ntiaj teb tias zinc piv ≥ 100 yog kev tiv thaiv zoo tiv thaiv kev xeb ntawm cov xim coated steel daim hlau
Daim ntawv pov thawj.Noj 0.5 hli substrate ua piv txwv, cov ntsiab lus plating ib square meter ntawm ib sab yuav tsum ncav cuag tsawg kawg yog 50g.

Yuav ua li cas xaiv hom txheej
Lub luag haujlwm tseem ceeb ntawm cov txheej txheej yog cuam tshuam rau ob qho tib si pom kev thiab kev tiv thaiv kev ua haujlwm.Cov xim ntawm cov txheej tuaj yeem muab faib ua cov organic pigments thiab inorganic pigments, nrog cov xim ci thiab luster;Inorganic pigments feem ntau yog lub teeb xim, tab sis lawv cov khoom siv tshuaj lom neeg thiab UV tsis kam yog superior rau cov organic pigments.
Feem ntau siv topcoats rau xim hlau daim hlau muaj xws li polyester (PE), silicon hloov polyester (SMP), siab durability polyester (HDP), thiab polyvinylidene fluoride (PVDF).Txhua lub tsho tiv no haum rau cov xwm txheej sib txawv, thiab peb pom zoo kom siv HDP lossis PVDF cov khoom thaum kev lag luam tso cai.

Rau kev xaiv ntawm primer, epoxy resin yuav tsum tau xaiv yog hais tias adhesion thiab corrosion kuj tseem ceeb;Yog xav paub ntxiv txog kev hloov pauv thiab UV tsis kam, xaiv polyurethane primer.
Rau cov txheej txheem rov qab, yog tias cov xim coated steel phaj yog siv los ua ib lub phaj, xaiv ob txheej txheej txheej, uas yog, ib txheej ntawm cov primer rov qab thiab ib txheej ntawm rov qab tiav.Yog tias cov xim coated steel phaj yog siv los ua cov khoom sib xyaw lossis cov phaj sandwich, ib txheej ntawm epoxy resin yog siv rau sab nraub qaum.

Cov nyhuv ntawm txheej thickness ntawm kev pab cuam lub neej
Cov xim hlau phaj txheej tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv corrosion, siv cov zaj duab xis txheej los cais cov khoom corrosive sab nraud.Txawm li cas los xij, vim tias lub microscopic tsos ntawm cov txheej txheej nws tus kheej, tseem muaj qhov pores, thiab cov pa me me ntawm cov dej vapor hauv huab cua tseem yuav cuam tshuam rau txheej txheej, ua rau blistering ntawm txheej thiab tejzaum nws ua rau cov txheej txheem txheej.Rau steel phaj, plating
Cov txheej (zinc plated lossis aluminium zinc plated) muaj kev cuam tshuam ntau dua rau lub neej ntawm steel phaj.
Rau tib txheej txheej tuab, txheej txheej txheej thib ob yog denser dua li cov txheej txheem txheej txheem, nrog kev tiv thaiv corrosion zoo dua thiab ua haujlwm ntev dua.Rau txheej txheej thickness, raws li qhov cuam tshuam cov kev ntsuam xyuas corrosion, peb pom zoo tias cov txheej pem hauv ntej yog 20 um lossis ntau dua, raws li cov yeeb yaj kiab txaus tuaj yeem tiv thaiv corrosion hauv lub sijhawm siv tau.
Tiv thaiv qhov tshwm sim ntawm corrosion (PVDF yuav tsum muaj cov txheej tuab tuab vim yog kev ua haujlwm ntev, feem ntau 25 μ M lossis ntau dua).
