1. Yuav ua li cas tswj hwm qhov zoo ntawm galvanized nto kev kho mob?
Degreasing: Siv Alkaline Tu Tus Neeg Sawv Cev (pH 10-12) los xyuas kom tshem tawm cov roj zinc
Tsis txhob siv cov kua qaub muaj zog thiab alkalis kom tsis txhob ua kom tsis txhob muaj kev puas tsuaj zinc txheej {}} Nws pom zoo kom siv tus neeg saib xyuas tshwj xeeb tu zinc {}}
Kev Kho Mob Deg Do Dotrness: Siv Anglasting: Siv Angular xuab zeb, kev ntxhib} μm, thiab lub ncha rau ntau dua los yog sib npaug nrog 25μm.
Kev daws teeb meem Lwm yam: Yog tias tsis tuaj yeem ua tau, kev sib tsoo tshuab hluav taws xob muaj peev xwm siv tau, tab sis nws yog ib qho tsim nyog los xyuas kom meej tias tsis muaj zinc ntsev..
Zinc Txheej Teeb Kho: Cov Khoom Siv Ib Zaug uas yuav tsum tau txau nrog zinc muaj ntau dua lossis sib npaug ntawm 38μm, lossis zinc alloy kho tus neeg sawv cev.
2. Dab tsi yog qhov chaw huv si ntawm galvanized txheej?
Kev Ntsuam Xyuas Pom: Qhov dawb ntawm cov roj, xeb, zinc ntsev (hmoov daj, mus txog {{}}}}} (ze rau theem dawb).
Ntsev kuab paug kom pom tau: so dej nrog dej deionized, thiab sim qhov kev coj ua tsawg dua lossis sib luag rau 50μs / cm.
3. Yuav Ua Li Cas Thiaj Tswj Raw Khoom Raw?
Primer (Epoxy Zinc-nplua nuj): Kev Cia Khoom Kub {}}}} degree, av qeeg 6 lub hlis (tsis tuaj yeem siv).
Zinc hmoov cov ntsiab lus yuav tsum muaj ntau dua lossis sib npaug rau 80% (qhov hnyav piv), thiab cov zinc tsawg dua lossis sib npaug li 5% ua ntej siv .
Topcoat (Fluorocarbon / PVDF): ◦ Muab tus neeg sawv cev ntawm 5,}}}}} khob {} khob {}
4. Cov ntsiab lus tseem ceeb ntawm cov txheej txheem sib xyaw yog dab tsi?
Kho lub sijhawm: Epoxy Primer xav tau kho rau 30 feeb tom qab kev sib xyaw ua ntej tom qab dhau lub sijhawm muaj (feem ntau 4 teev).
Kev yuav tsum tau pom: Siv 120- mesh lim rau lim kom tshem tawm impurities thiab zam nozzle thaiv ua rau uneven txheej {}}
5. Cov kauj ruam tseem ceeb hauv ob lub tsho loj thiab ob-bake siv li cas?
Primer daim ntawv thov (thawj lub tsho tiv no)
Txau tsis: Cua siab 0.4-0.6 mpa mpa ci, txau} Ncaws pob ceev {} cm / s .
Qhuav zaj duab xis tuab tswj 80-100 {{{{{{{1 {1 {1 {{{{{{}
Ci kho: kev nplij siab cua sov: 80-100}} 2 feeb (cua sov epoxy
Daim ntawv thov Popcoat (thib ob lub tsho tiv no)
Cov kev kho deg: Tom qab tus thawj coj tau kho tau, maj mam zom nrog 320
Txau tsis muaj cov tshuaj lom zem: FluorocarBon Sab saum toj yuav tsum tau txau nrog cov tshuaj txau siab (siab tshaj}} {{.
Ci thiab kho ntshav: Theem cua sov: 12 feeb × 15 feeb →
