1.How yog txheej txheej tuab cuam tshuam rau corrosion tsis kam?
Lub luag haujlwm tseem ceeb ntawm cov txheej yog ua kom lub cev cais tawm ntawm cov ntawv me me (xws li cov pa yas, thiab cov pa roj av, noo noo, cov ntsev, cov kuab paug, thiab lwm yam). Tsis pub dhau qee qhov ntau, raws li txheej txheej txheej coating nce, thiab txoj kev mus rau kev tawm tsam ntev dua, yog li ncua sij hawm nws yuav siv sij hawm rau lub substrate.
2.How ua txheej txheej tuab cuam tshuam rau corrosion tsis kam?
Lub zog ntawm kev thaiv lub cev
Lub thicker txheej txheej, qhov ntau ua tiav lub cev lub cev nws cov ntaub ntawv, thiab ua tau zoo dua nws yog nyob rau hauv kev thaiv kev nkag ntawm ya raws, oxygen, thiab ions. Piv txwv li, hauv cov av noo hiav txwv ntug dej ib puag ncig, ib txheej tuab tuaj yeem qeeb tus nqi ntawm cov tshuaj txheej dhau ntawm cov ntug ntawm substrate.
"Zam Txim" ntawm cov txheej tsis xws luag
Cov tsis muaj peev xwm me me yog qhov tsis muaj peev xwm ua cov txheej txheem me me, txawm tias muaj qhov tsis xws luag Thaum tsis xws luag nyob rau hauv nyias txheej txheej yog feem ntau yuav ncaj qha rau substrate, ua rau corrosion hauv zos kom kis tau sai.
Tus txheej txheej tus kheej cov laus tiv taus
Thaum siv, txheej yuav muaj hnub nyoog (xws li hmoov thiab tawg) kev hloov kho tshiab, tuaj yeem tswj hwm cov txheej txheem kev ntseeg siab, tuaj yeem tswj hwm cov nyhuv tiv thaiv ntev dua ntawm cov substrate; Thinings nyias yuav poob lawv txoj kev tiv thaiv vim kev laus hauv lub sijhawm luv luv.
3.Nws tuab dua txheej txheej, qhov zoo dua?
Txo kev khwv nyiaj txiag
Nce cov txheej txheej txheej coating yuav ua kom cov khoom siv raw thiab ua tiav, thiab tom qab kev txhim kho hauv corrosion tsis kam yuav maj mam qeeb.
Qhov cuam tshuam tsis zoo ntawm txheej ua haujlwm
Dhau ib txheej yuav ua rau:
Txo cov adhesion: kev sib raug zoo ntawm cov txheej thiab cov txheej txheem lossis cov primcoat yuav tsis muaj zog vim yog cov tuab tuab si tev thiab ua kom muaj xeb ntau dhau;
Cov txheej txheem kho kom huv, thaum lub sij hawm kho tuab yuav ua npuas los yog pinholes vim tias ua tsis tiav kev hloov kho sab hauv los, txo cov tshuaj tiv thaiv corrosion.
Deteriorated yooj: tuab cov txheej txheem tuab yog nquag mus tawg thaum lub substrate yog deformed, tsim cov charosion corrosion tshiab.
4.What yog qhov sib txawv ntawm cov thuv thickness yuav tsum muaj rau cov xwm txheej sib txawv?
Ib puag ncig sab hauv DUA: Kev tiv thaiv yooj yim, tswj tus nqi tswj hwm
Sab nraum zoov muaj huab cua: sib npaug corrosion tsis kam thiab kev lag luam
Ntug dej hiav txwv / siab av noo ib puag ncig: ntxiv dag zog teeb meem, tiv thaiv cov ntsev nkag
Tshuaj lom neeg cov tshuaj lom neeg: Tshaj dhau kev cais tawm, txuas ntxiv kev pabcuam lub neej
5.Yog txheej tuab ib qho tseem ceeb cuam tshuam rau cov corrosion tsis kam ntawm cov xim coated coils?
Tsis pub dhau cov muaj nuj nqis tsim nyog (saum toj no tus nqi tseem ceeb thiab nyob rau hauv Optimal tuab), nce cov thickness tuaj yeem txhim kho cov corrosion tsis kam; Txawm li cas los xij, qhov muag dig muag yuav tsum tau zam, thiab cov qauv tsim yuav tsum tau ua ke nrog ib puag ncig, ua tiav) kom ua tiav qhov sib npaug zoo tshaj plaws ntawm kev tiv thaiv effection thiab kev lag luam. Nyob rau tib lub sijhawm, cov yam ntxwv xws li txheej txheej sib xyaw ua ke yog cov khoom ua kom zoo dua (xws li cov tshuaj pleev roj polyester) kuj tseem muaj cov tshuaj tiv thaiv fluorocar) kuj tseem ua kom haum rau cov tshuaj corrosion.
