1.What yog qhov yuav tsum tau ua rau coating tuab thiab kev sib xws?
Thickness Yuav Tsum Tau: Txawv txawv tsim raws li qhov chaw nyob ntawm cov chaw thiab kev tiv thaiv corrosion. Feem ntau:
Sab nraud lub cev Panels (xws li lub qhov rooj thiab hoods): 8-15μm (uas yuav tsum tau coj mus rau hauv tus account anti-corrosion thiab tsos tom qab pleev xim;
Sab hauv lub cev panels (xws li cov tsev thiab ncej): 5-10μm (tsom mus rau ntawm qhov yooj yim tiv thaiv corrosion;
Qhov chaw nyob rau hauv high-corrosion ib puag ncig high-corrosion)
Kev sib txawv: cov tuab tuab ntawm cov txheej ntawm tib lub phaj yuav tsum tsawg dua lossis sib npaug ntawm ntug thiab qhov chaw yuav tsum tsis pub dhau 3μm (kom tsis txhob muaj ntau dua 3μm (kom tsis txhob muaj kev sib zog ntawm thaj chaw hauv nroog).
2.Qhov dab tsi yog qhov yuav tsum tau ua rau cov kev sib raug zoo ntawm cov txheej rau electrogalvanized pob tsheb daim hlau?
Cov txheej yuav tsum tau nruj ua ke nrog lub substrate kom tsis txhob poob tawm thaum ua tiav lossis siv. Yuav tsum tau xeem:
Dabtsi yog khoov xeem: Raws li GB / T- T 22319 tus qauv, khoov lub phaj 180 (lub phaj mandrel inch yog 2 zaug lub phaj tuab), thiab txheej tsis muaj tev lossis tev;
Kev kuaj: Siv riam sib tsoo rau khawb ib qho chaw 1 hli
3.Qhov yog qhov yuav tsum tau rau kev ua kom corrosion tsis kam?
Neutral ntsev tsuag kev tshuaj ntsuam (NSS): Nyob ntawm qhov yuav tsum tau ua ntej 72-120 teev yam tsis muaj dhau 78-72 teev yam tsis muaj ib qho muaj xeb dawb; High corrosion resistance xeem (xws li zinc alloy txheej) yuav tsum dhau ntau tshaj 200 teev yam tsis muaj xeb liab (hauv paus corrosion).
Kev ya raws thiab kub ua kom tau: tom qab tau muab tso rau hauv ib puag ncig ntawm 40℃thiab 95% txheeb ze cov av noo rau 1000 teev tsis muaj bubbling los yog xeb.
4.What cov mob yuav tsum ua kom zoo sib ntsib?
Cov tsos mob: tsis muaj hauv qab qhov tshwm sim, pits, khawb, qhov tob dua lossis sib npaug ntawm cov phaj tsawg dua lossis sib npaug rau 5%);
Roughness (ra): sab nraud phaj yuav tsum tau tswj hwm ntawm 0.8-1.6μm (los xyuas kom meej cov zaj duab xis tha xim tom qab pleev xim rau tsawg dua 2.0μm;
Cov roj nyob: Cov roj av saum npoo tsawg dua los yog sib npaug nrog 5mg / m² (los ntawm kev sim so lossis kev siv sijhawm ua kom tsis txhob cuam tshuam cov nplaum ntawm cov txheej txheem).
5.Qhov yog tus txheej txheem tseem ceeb ntawm electrogalvanizing?
Cov Txheej Txheem Electroplating Cov Txheej Txheem: Cov ntsiab lus tau txais cov phiaj xwm kev plating thiab chloride zinc plating, thiab ceev tam sim no tuaj yeem tswj tau ntawm 10-30a / dm².
Ntxiv: Cov neeg sawv cev ua kom muaj zog thiab cov neeg sawv cev theem yuav tsum tau ntxiv kom ntseeg tau tias cov txheej ci thiab tiaj tus, thiab kom tsis txhob pinholes thiab burrs.
Kev tswj tam sim no thiab kub: Qhov ceev faj tam sim no yuav tsum tau hloov kho raws li lub phaj (piv txwv li, thaum muaj qhov tsis sib xws tau sib tw tam sim no 15-25A / dm²).
Plating daws qhov kub tau kub: chloride system yog tswj hwm ntawm 40-30 degree, thiab qhov sib txawv ntawm qhov sib txawv yog tsawg dua los yog sib npaug rau ± 2 qib (kom tsis txhob muaj qhov tsis xwm yeem).
