1.Vim li cas lub lightfastness cuam tshuam tom qab kov-up?
Tsis tiav txheej system:
Thawj txheej: substrate → chemical conversion txheej (xws li phosphate txheej) → primer (feem ntau yog epoxy, muaj zog adhesion thiab anti{0}} xeb) → topcoat (polyester, silicon- hloov polyester, PVDF, thiab lwm yam., muab xim thiab huab cua tsis kam). Qhov no yog ua tiav, txheej - los ntawm - txheej txheej tiv thaiv txheej txheem.
Ntawm -site kov-up: feem ntau tsuas yog 1-2 txheej ntawm topcoat lossis universal touch-up xim tuaj yeem siv ncaj qha tom qab ntxuav cov khawb. Cov txheej txheem tshuaj lom neeg hloov pauv tseem ceeb thiab cov primer nplooj siab ploj lawm, ua rau lub hauv paus tsis muaj zog adhesion.
Kev tsim kho tej yam kev mob sib txawv:
Cov txheej txheem tseem ceeb ntawm lub Hoobkas: ua ntej- kev kho mob hauv chav ua haujlwm huv, tom qab ntawd pleev xim rau cov menyuam txheej sib npaug, thiab sai sai ci thiab khov kho ntawm qhov kub thiab txias (PMT txog 200-}240 degree) los ua ib qho tuab, tag nrho cov xim sib txuas sib txuas.
Ntawm -qhov chaw kov-thaum pleev xim: phau ntawv txhuam los yog tshuaj tsuag, qhov kub thiab txias los yog ntuj kho. Lub leveling, thickness uniformity thiab curing℃ntawm cov xim zaj duab xis yog nyob deb inferior rau cov thawj manufacturers. Ib daim duab xim uas kho tsis txaus yuav ua rau muaj huab cua tsis zoo.
2.Dab tsi yog qhov cuam tshuam ntawm cov khoom sib tw?
Nws yog ib qho nyuaj rau nrhiav refinish xim uas yog raws nraim tib yam tshuaj muaj pes tsawg leeg thiab huab cua tsis kam qib raws li raw khoom. Txawm hais tias cov xim nyob ze, cov txheej txheem resin (xws li siv cov xim alkyd zoo tib yam los kov PVDF topcoat) yuav tsis sib xws, ua rau muaj kev sib raug zoo tsis zoo thiab ua rau muaj kev laus sai.
Cov ntsiab lus thiab kev ua tau zoo ntawm UV absorbers, stabilizers thiab lwm yam additives tsis tuaj yeem muab piv nrog cov khoom qub.
3.Qhov chaw kho li cas?
Ntxuav: Siv cov kuab tshuaj (xws li cov nyias nyias) kom tshem tawm cov roj thiab plua plav hauv thiab ib ncig ntawm qhov chaw khawb.
Sanding: Siv cov ntawv xuab zeb zoo (xws li 400 # lossis siab dua) txhawm rau txhuam thaj chaw khawb rau hauv qhov chaw zoo nkauj (feathered ntug), thiab nthuav cov xuab zeb kom ntxiv adhesion. Ua tib zoo tshem cov xuab zeb plua plav.
Anti- xeb: Yog tias cov hlau raug, nco ntsoov siv cov tshuaj tiv thaiv tshwj xeeb - xeb xim lossis epoxy zinc- nplua nuj primer kom npog tag nrho thaj chaw hlau.
4.Yuav ua li cas xaiv cov khoom siv?
Nws yog qhov zoo tshaj yog hu rau cov chaw tsim khoom lossis cov chaw muag khoom xim -coated coils los yuav cov xim kho tshwj xeeb uas muab los ntawm cov chaw tsim khoom qub.
Kev xaiv thib ob: Siv zoo-paub cov npe ntawm sab nraum zoov acrylic polyurethane xim thiab fluorocarbon xim kho cov neeg ua haujlwm, uas muaj cov huab cua tsis zoo. Ib txwm paub meej tias compatibility nrog lub substrate thiab thawj txheej.
5.Ib qho lus qhia rau patching?
Rau qhov tsis yog - qhov tseem ceeb, tsis yog - ib puag ncig corrosive hnyav, thiab me me - thaj chaw khawb: kho raws li cov lus saum toj no - cov txheej txheem nruj tuaj yeem siv los ua tus txheej txheem tu kom ncua tag nrho cov kev pab cuam lub neej, tab sis koj yuav tsum lees txais cov xim sib txawv thiab qhov tseeb tias nws tuaj yeem ua ib nrab rov ua dua yav tom ntej {{4}.
Rau qhov tseem ceeb, ib puag ncig corrosive heev (xws li kev lag luam tshuaj lom neeg, thaj chaw ntug hiav txwv, thaj chaw UV siab) lossis loj - kev puas tsuaj loj: kev kho tsis yog qhov kev daws teeb meem ntev -. Txoj kev nyab xeeb tshaj plaws yog los hloov tag nrho cov xim -coated phaj los xyuas kom meej lub sealing thiab durability ntawm tag nrho cov khoom.
Cov lus ceeb toom tseem ceeb: Yog tias cov xim no-coated coil yog siv rau hauv cov tshuaj khib nyiab kho qhov chaw uas tau hais hauv koj cov lus nug dhau los, tom qab ntawd kev kho tsuas yog kev ntsuas kub ntxhov ib ntus xwb, vim tias cov tshuaj corrosion yuav nkag mus sai sai ntawm thaj chaw kho, thiab hloov nrog cov corrosion ntau dua - cov ntaub ntawv tiv taus (xws li FRP, stainless hlau, thiab lwm yam) yuav tsum tau npaj kom sai li sai tau.
