1.Hho li cas xaiv substrate?
Kub - dip galvanized coils (xws li sgccized coils feem ntau yog siv thickinges, nrog tuab ib txwm muaj txij li 0.15 rau 2.0 hli. Dav tau sib txawv raws nyob ntawm cov kab kab tshwj xeeb (feem ntau 1000 rau 1500 hli). Lub thickness thiab nto zoo ntawm zinc txheej (piv txwv li, tsis muaj kab tshaj cum los yog spy {{11} painted txheej. Piv txwv li, substrates nrog lub high zinc txheej yog qhov tsim nyog rau kev ua kom huv si corrosion.
2.How qhib phau ntawv thiab txuas?
Tus dov rau galvanized substrate yog unwound siv ib tug unwinder kom tshem tawm cov ntawv qhwv lossis tiv thaiv zaj duab xis lossis tiv thaiv zaj duab xis.
Yog tias muaj ntau cov yob tau tsim tawm tsis tu ncua, cov khoom siv vuam yuav tsum tau txuas qhov kawg ntawm cov yob yav dhau los mus rau kev ua haujlwm ntau lawm. (Lub cheeb tsam welded yuav tsum tau polished kom tsis txhob cuam tshuam rau kev sib txawv ntawm cov txheej txheem tom qab.)
3.Yog ua haujlwm ua haujlwm?
Ncab
Lub Hom Phiaj: Tshem tawm cov impurities xws li roj, plua plav, thiab dov tawm ntawm substrate nto kom tiv thaiv lawv los ntawm kev cuam tshuam nrog txheej nplaum.
Txoj Kev: Siv cov tshuaj ntxuav alkaline (xws li sodium hydroxide tov) lossis tsuag ntxuav, ua ke nrog kub siab (50-70 degree) los txhim kho degreiting. Yaug cov tshuaj alkaline alkaline nrog cov dej huv.
Cov Mob Chaw (Xaiv tau)
Ua kom cov passivation txheej ntawm galvanized substrates, xws li siv cov qauv acid (xws li phosphoric acid) los tsim cov tshuaj nplaum ntawm cov tshuaj hloov pauv hloov tshiab.
Kev Kho Mob Hloov Siab Txheem Hloov Ntshav
Lub Hom Phiaj: Ua cov yeeb yaj kiab hloov pauv kev hloov pauv nyias nyias (xws li chromium {{free passionion ntawm txheej thiab substrate thiab ntxiv txhim kho corrosion tsis kam.
Cov txheej txheem ntau yam:
Kev kho mob raws li kev kho mob, cov txheej txheem ib txwm muaj ua kom muaj kev tiv thaiv corrosion zoo, tab sis muaj maj mam hloov los ntawm chromium {}} cov txheej txheem pub dawb.
Chromium - Pub dawb passivation: kev kho mob xws li zirconate zoo ib yam li Chromate, ua rau lawv cov qauv tseem ceeb. Tom qab kev kho, nws yuav tsum tau qhuav thaum tsis tshua kub (60-80 degree) kom tshem tawm cov dej noo yam tsis muaj kev hloov pauv ntawm kev hloov ua zaj duab xis.
4.Qhov txheej txheem txheej txheem txheej txheem?
Primer daim ntawv thov (Yeem, thaum thov)
Rau cov khoom uas yuav tsum muaj siab ua kom zoo (xws li cov ntawv thov sab nraud), xws li Epoxy Primer) yuav tsum tau txhim kho adhesion thiab corrosion tsis zoo ntawm substrate thiab lub topcoat.
Daim ntawv thov cov qauv: cov menyuam daim ntawv thov (feem ntau siv, siv cov roj hmab uas tau hloov mus rau sab npoo av), txau, lossis cov duab tshwj xeeb).
Daim Ntawv Thov Popcoat
Xaiv hom txheej txheej (xws li PE, SMP, PVDF, thiab lwm yam) raws li cov khoom uas yuav tsum tau raws li cov qauv (xim thiab ci tuaj yeem yog customized).
Daim ntawv thov hom: Cov menyuam daim ntawv thov tseem yog thawj txoj kev, nrawm (feem ntau 10μm qhuav zaj duab xis tuab, tab sis 50μm lossis ntau dua yog li thaum thov).
Yog tias ob npaug {-} }ating} Cov txheej txheem txheej (Primer Team)
5.Qhov dab tsi ci thiab kho cov kauj ruam?
Pib kom qhuav (ua ntej - kho)
Cov coated substrate nkag mus rau qhov pib cub, qhov twg nto ya raws tau qhuav ntawm qhov tsawg (80} 12 1}} 120} 12}
High -} kev kho kub
Nkag mus rau qhov cub kho, qhov kub thiab sijhawm tswj tau raws li hom txheej txheej:
PE, SMP: Kho qhov kub thiab txias 180-220 degree, kho lub sijhawm 30-60 vib nas this.
HDP, PVDF: Kev kho tus kub 220 {}}}}}} 250 surch, kev kho lub sijhawm uas muaj fluorocarbon resin, txhim kho huab cua tiv kev zam).
Thaum lub sij hawm kho tus txheej txheem, cov hnyav nyob rau hauv txheej txheej armaporates, thiab resin undergoes nroj tshuag
Cua txias
Lub cured substrate nkag mus rau seem txias, uas txias los ntawm huab cua lossis dej ntws rau hauv lub npoo) kom tsis txhob muaj qhov tawg ntawm cov cua txuas ntxiv.
