Sib ntaus Underbody Corrosion nrog Sealant
Txheem
Lub cev ntawm lub tsheb yuav zoo nkauj, tab sis hauv qab tsis tuaj yeem tsis quav ntsej. Txawm hais tias lub tsheb ci nrog polish, hauv qab tseem tuaj yeem ua rau poob tsis tau. Hauv qab corrosion yog qhov tsis ua haujlwm rau kev tshuaj ntsuam xyuas. Qhov tsuas yog qhov uas muab kev tiv thaiv kev ruaj ntseg ntawm lub log npog, sills thiab underbody los ntawm corrosion yog kab noj hniav txheej thiab sealant. Hmoov tsis zoo, tsis muaj ib qho ntawm cov kev ntsuas muab kev daws teeb meem mus tas li thiab kev kuaj xyuas ib ntus, tshwj xeeb tshaj yog nyob rau hauv cov tsheb qub, yog qhov tsim nyog. Cov lus qhia no yog txhua yam hais txog kev sib khi hauv qab (Am: primer) thiab yuav qhia koj txhua yam koj xav paub txog kev sealing kev tshaj lij los tiv thaiv corrosion.
Kev sib xyaw ua ke tsis raug
Cov tsheb tseem ua los ntawm cov hlau feem ntau. Tsis muaj lwm yam khoom muaj xws li qhov nyiaj tshuav ntawm qhov txias formability, lub zog thiab tus nqi tsim nyog. Lub ntsiab tsis zoo ntawm steel panels yog lawv cov ntsiab lus hlau siab. Nyob rau hauv kev sib cuag nrog noo noo - thiab nyob rau hauv qhov phem tshaj - nrog txoj kev ntsev, hlau pib xeb. Yog tias qhov no tsis pom thiab tshem tawm hauv lub sijhawm, xeb yuav maj mam kis.
Underseal pab, tab sis tsis tas mus li
Underseal yog cov tshuaj tiv thaiv, feem ntau muaj bitumen, zoo heev rau hauv qab sealing. . Niaj hnub no, txheej txheej tiv thaiv yog siv rau cov tsheb tshiab thaum lub sij hawm tsim kho, uas kav ntau xyoo. Underseal yog siv rau hauv ib txheej ½ mm. Cov khoom siv roj hmab sau cov xuab zeb qhov thiab tsis khawb. Nyob rau tib lub sijhawm, lub sealant nyiam qhuav tawm. Yog li ntawd, tom qab tsis pub dhau 8 xyoo, cov txheej txheem tiv thaiv yuav tsum tau ua tib zoo xyuas. Yog tias muaj cov kab nrib pleb lossis txheej txheej tawm, yuav tsum tau ua tam sim.
Trap hu ua qub foob
Qee lub sij hawm noo noo yuav muab khi rau hauv lub tsho qub primer. Yog tias cov dej ntsev tau los ntawm cov txheej tiv thaiv thiab cov ntawv hlau, nws yuav tsis tuaj yeem tawm. Cov dej seem ntawm cov hlau ua rau corrosion. Nyob rau hauv cov ntaub ntawv no, lub qub roj foob ua qhov opposite ntawm nws thawj lub hom phiaj - es tsis txhob tiv thaiv corrosion, nws nkoos lub tsim ntawm xeb.
Daim ntawv thov thiab txhim kho cov txheej hauv qab
Yog li ntawd, txau ib txheej ntawm dinitrol los yog tektyl ntawm cov txheej qub ntawm sealant tsis pab ntau. Txhawm rau tiv thaiv lub hauv qab ntawm lub tsheb mus tas li los ntawm kev xeb, cov txheej txheem qub yuav tsum tau muab tshem tawm. Cov xov xwm phem yog tias nws nyuaj los yog kim. Qhov xwm zoo yog tias tsuas yog thaj chaw puas tsuaj loj heev yuav tsum tau kho. Raws li txoj cai, cov no yog cov npoo ntawm qhov chaw pib lossis lub log arches. Qhov saum npoo uas kaw qhov nruab nrab ntawm lub cev hauv qab feem ntau tseem zoo ib yam thoob plaws lub neej ntawm lub tsheb.
Cov txheej txheem tshem tawm hauv qab
Muaj peb txoj hauv kev los tshem tawm cov foob hauv qab:
1. Kev ceev tshem tawm nrog scraper thiab steel txhuam
2. Kev kub ntxhov
3. Sandblasting
 Kev tshem tawm ntawm phau ntawv nrog lub scraper thiab txhuam yog cumbersome heev thiab yog tshwj xeeb tshaj yog tsim nyog rau tshem tawm xoob xeb nyob rau hauv qhov chaw uas muaj qhov pom. . Kev siv thev naus laus zis yog siv tsawg ntawm no. Nqus bitumen yuav clog rotating txhuam thiab sandpaper sai heev. Kev ruaj ntseg phau ntawv ua haujlwm yog qhov kev xaiv zoo tshaj plaws. Ib rab phom cua sov tuaj yeem ua haujlwm yooj yim dua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw nyuaj. |
| Burnout yog tus cwj pwm ntawm avid tus kheej qhia tus tswv . Peb qhia tawm tsam kev ua si nrog hluav taws. Ua ntej koj paub, koj tau hlawv koj lub tsheb thiab yog li koj lub chaw nres tsheb tag nrho. |
| Thaum kawg, sandblasting yog ib txoj hauv kev nrov rau tshem tawm cov foob hauv qab. . Muaj ob txoj hauv kev sib txawv: abrasive и tsis-abrasive . Thaum abrasive blasting cov khoom granular yog pub rau hauv qab ntawm lub tsheb siv compressed cua. Qhov zoo tshaj plaws-paub txoj kev yog sandblasting, txawm hais tias muaj ob peb lwm yam ua tau abrasives: ci dej qab zib, iav, yas granules, nutshells thiab ntau ntxiv. Qhov zoo ntawm abrasive blasting yog guaranteed kev vam meej. Cov txheej tiv thaiv raug tshem tawm hauv qab sai sai thiab zoo, thiab pheej yig heev. Nws qhov tsis zoo yog tus nqi pov tseg uas nws tsim. Tsis tas li ntawd, vim muaj kev kub siab dhau los yog qhov tsis zoo abrasive, cov kab hauv qab noj qab haus huv tuaj yeem raug puas tsuaj. Ib qho kev xaiv zoo yog cov cov txheej txheem tsis-abrasive blasting : Hloov cov tawv abrasive, cov dej khov qhuav qhuav siv cov pa roj carbon dioxide khov kho uas tawg thaum lawv tsoo cov txheej tiv thaiv, tshem tawm tau yooj yim. Nrog rau kev zam ntawm cov txheej txheem tiv thaiv qub, kev ua dej khov qhuav yog tsis muaj pov tseg thiab muaj kev nyab xeeb kiag li rau hauv qab. Lwm txoj hauv kev yog kev tu dej siab. qhov tsis zoo ntawm no lwm txoj kev zoo heev yog lawv cov nqi. Cov dej khov qhuav blaster nqi xauj tsev approx. € 100-300 (£ 175-265) ib hnub. Yog li ntawd, txoj kev no yog tshwj xeeb tshaj yog haum rau high-end tsheb xws li cov khoom kim heev kev ua si tsheb los yog vintage tsheb. Qhuav dej khov blasting los ntawm ib tug kws muab kev pab cuam yuav raug nqi koj € 500-1000. |
Kev tshem tawm xeb
Ua ntej siv lub sealant tshiab, qee qhov kev npaj ua haujlwm yog qhov tsim nyog, feem ntau yog tshem tawm cov xeb ntxiv. Cov hniav txhuam hniav thiab txhuam hniav zoo tshaj plaws, txawm hais tias lawv tsuas yog tshem tawm cov xeb xeb. Lub kaum sab xis grinder tso cai rau koj ua haujlwm ntawm qhov tob, tab sis tib lub sijhawm koj pheej hmoo sib tsoo cov khoom noj qab haus huv. Yog li ntawd, peb pom zoo kom siv ib tug xeb converter. Cov tshuaj yog siv nrog ib tug txhuam hniav thiab yuav tsum tau tso cai rau tsau rau hauv. Thaum cov xeb liab tau hloov mus rau hauv cov xim dub, nws tuaj yeem raug tshem tawm nrog cov ntaub qhwv. Thaj, xeb qhov vuam yuav tsum tau tso tseg rau cov kws tshaj lij kev pabcuam.
Tseem ceeb heev: degrease thiab daim kab xev
Txheej yuav tsum zoo ib yam li painting hlau: pre-degrease qhov chaw . Silicone ntxuav ua pov thawj tias yog qhov tsim nyog tshaj plaws. Siv cov txheej tiv thaiv thiab tshem tawm tom qab nws tau ua haujlwm. Tom qab ntawd, lub cev yuav tsum tsis txhob kov lwm yam khoom. Txau tsis pub Wd-40 los yog nkag mus rau roj. Txwv tsis pub, koj tuaj yeem pib cov txheej txheem degreasing dua.
Tag nrho cov khoom txav mus los thiab kub yuav tsum tsis txhob raug kho nrog sealant. Yog li ntawd, nws raug nquahu kom npog lub kauj iav thiab tso pa tawm nrog cov ntawv xov xwm. Sealant tuaj yeem cuam tshuam kev txav mus los. Thaum tso tawm, cov khoom ua rau muaj hluav taws kub. Yog li xyuas kom tsis muaj dab tsi tshwm sim ntawm no! Daim kab xev sab nraum lub qhov rais sill nyob rau hauv ib nrab. Thaj chaw no kuj yuav tsum tau muab kaw.
Tshiab foob
Tom qab sandblasting los yog sanding lub hauv qab mus rau liab qab panels, tshuaj tsuag primer yog pom zoo. Qhov no yuav cia lub sealant ua raws li kev cai. Tsuas yog tsuag rau ntawm primer thiab cia nws qhuav.
Underseal tam sim no muaj nyob rau hauv cov kaus poom aerosol thiab yuav tsum tau txau rau hauv cov hlau txheej 0,5 mm . Hauv qhov no, nws tsis pom zoo kom siv ntau dhau. Ib txheej tiv thaiv tuab txhais tau tias tsis muaj dab tsi ntau tshaj li cov khoom pov tseg. Cov txheej tiv thaiv tshiab yuav tsum tau tso cai kom qhuav rau 4 teev. Tom qab ntawd, daim kab xev tuaj yeem raug tshem tawm. Cov tsos ntawm qhov pib tam sim no tuaj yeem pleev xim rau hauv cov xim ntawm lub tsheb. Tom qab hardening, primer tuaj yeem pleev xim rau.
