Tsis tas li ntawd, kev puas tsuaj (s khawb, dents, chips) tuaj yeem tau los ntawm kev tawm hauv lub tsheb hauv qhov chaw nres tsheb.

Tsheb muaj lwm tus yeeb ncuab loj heev: lub sijhawm, uas tsis zam lub cev steel. Muab qhov txuas ntawm feem ntau ntawm peb cov tswv tsheb rau lawv lub tsheb, kev tshem tawm cov teebmeem ntawm corrosion yog ib qho ntawm cov haujlwm tseem ceeb ntawm kev kho lub cev.

Nws yog ib qho tsim nyog hais tam sim ntawd tias kev kho lub cev thaum tsis muaj kev txawj ntse thiab cov cuab yeej tshwj xeeb tuaj yeem ua tau tsuas yog nrog kev puas tsuaj me me uas tsis cuam tshuam rau cov khoom thauj khoom ntawm lub tsheb.

Kev tshem tawm xeb

Kev sib ntaus tawm tsam corrosion yog ib qho ntawm cov txheej txheem siv sijhawm ntau tshaj plaws, tab sis yog tias nws tsis saib xyuas, nyob rau lub sijhawm luv luv ntawm lub tsheb uas tseem tsis tau muaj kev sib tsoo yuav poob nws qhov kev pom zoo. Zoo, yog tias lub sijhawm tau ploj lawm, thiab xeb ua rau nws tus kheej hnov ​​nrog cov pob liab liab, nws yog ib qho tseem ceeb los ntsuas qhov chaw thiab tshem tawm foci ntawm corrosion.

Kev ntxuav lub cev los ntawm xeb cuam tshuam nrog ob theem ntawm nws qhov kev siv: kev tu txhua yam thiab kev kho mob nrog cov tshuaj tshwj xeeb. Rau thawj theem ntawm kev ua haujlwm, koj yuav xav tau

• hlau txhuam (phau ntawv los yog hauv daim ntawv ntawm cov khoom siv rau lub laum lossis grinder "),
• ib qho zoo ntawm cov ntawv xuab zeb nrog grit ntawm 60-80,
• cov nqaij mos

Muaj nyob rau hauv cov kua, gel thiab aerosol daim ntawv. Yog lawm, txhua tus hloov kho muaj lawv tus kheej tshwj xeeb muaj pes tsawg leeg, yog li ntawd, lawv yuav tsum tau ua kom paub meej txog cov cai rau lawv siv thiab ua raws li kev ntsuas kev nyab xeeb uas tau pom zoo.

• Ua ntej tshaj plaws, koj yuav tsum tau ntxuav lub tsheb kom huv si thiab txheeb xyuas cov hnab ris ntawm corrosion ntawm nws qhov chaw.

• Mechanically (nrog txhuam los yog cov ntawv xuab zeb), cov pob zeb xeb raug ntxuav kom zoo "hmoov" hlau. Tsis txhob siv cov tshuaj tiv thaiv corrosion tam sim ntawd; Nws yog ib qho nyuaj rau kwv yees qhov tob ntawm qhov lesion.

• Txawm hais tias koj sim ua nyuaj npaum li cas, cov hnab me me ntawm cov xeb yuav nyob hauv qhov hws lossis kab noj hniav uas tsis tuaj yeem nkag mus rau txhua yam. Nws yog nyob rau theem no uas lub tshuab hloov xeb yog tsim (raws li cov lus qhia rau nws siv), uas yuav tsum tsis tsuas yog yaj tag nrho nws, tab sis kuj npog thaj tsam cuam tshuam nrog ib hom primer haum rau ntxiv puttying. Cov lus qhia dav dav tsis tuaj yeem muab rau ntawm no: qee cov qauv yuav tsum tau yaug tom qab qee lub sijhawm tshuaj tiv thaiv, thaum lwm tus, ntawm qhov tsis sib xws, nyob twj ywm ntawm qhov chaw thov kom qhuav tag.

• Nws feem ntau tshwm sim tias corrosion noj hlau mus rau hauv nyias "mesh" lossis txawm tias dhau los. Los ntawm lub qhov tuaj yeem raug kaw nrog fiberglass siv cov tshuaj epoxy, tab sis tseem yog qhov kev daws teeb meem zoo tshaj plaws yuav yog tin cheeb tsam thiab solder ib thaj hlau. Qhov chaw tinned yuav tsis corrode ntxiv thiab thaj ua rau thaj tuaj yeem yooj yim pierced los siv cov txheej nyias nyias ntawm putty rau saum.
• Peb yuav tsum tsis txhob hnov ​​​​qab tias qhov chaw ntxuav yuav tsum tau kho tam sim nrog cov tshuaj tiv thaiv corrosion. Nyob rau theem nruab nrab ntawm kev ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau cais tawm txawm tias me ntsis ntawm kev sib tsoo ntawm cov dej.

Sib ntaus tawm tsam khawb

Kev khawb ntawm lub cev tsheb yog ib qho mob taub hau. Muaj ntau qhov laj thawj rau nws qhov tsos, txawm tias koj tsis suav qhov kev huam yuaj: pob zeb thiab cov khoom txawv teb chaws ya tawm hauv qab lub log, cov ceg ntoo thiab cov ntoo tsis raug txiav, cov menyuam yaus ua si tes lossis lwm tus neeg lub siab phem.

Raws li txoj cai, hauv lub teeb pom kev zoo, qhov no tuaj yeem pom nrog lub qhov muag liab qab, yog tias xav tau, koj tuaj yeem siv lub iav tsom iav.

Rau kev puas tsuaj sab nraud, thaum tsuas yog ib txheej ntawm cov kua roj vanish raug khawb, cov polishes tshwj xeeb (kua lossis muab tshuaj txhuam) lossis polishing sticks, piv txwv li, pom zoo los ntawm ntau tus tswv tsheb Kho nws Pro lossis Scratch Free, tuaj yeem siv los tshem tawm cov teeb khawb. Lub hauv paus ntsiab lus ntawm nws daim ntawv thov yog yooj yim:

1. Qhov saum npoo yog huv si ntxuav los ntawm av thiab hmoov av nrog detergent thiab qhuav.
2. Polish yog siv rau qhov chaw puas thiab rubbed rau hauv qhov chaw nrog ib daim ntaub huv, qhuav paj rwb hauv ib ncig.
3. Tom qab cov muaj pes tsawg leeg tau qhuav tag (raws li cov lus qhia txuas nrog rau cov khoom), qhov kawg polishing yog nqa tawm.

Yog tias khawb tob dua, yuav muaj teeb meem ntau ntxiv. Koj yuav xav tau ib tug cwj mem rov qab (piv txwv li TSHIAB TON) lossis xim me me; lub sij hawm nyuaj nyob rau hauv ob qho tib si yog qhov raug xaiv ntawm qhov xav tau ntxoov ntxoo.

1. Qhov saum npoo yog ntxuav kom huv si nrog tshuaj zawv plaub hau, qhuav thiab degreased. Txhawm rau tiv thaiv cov xim los ntawm kev nkag mus rau qhov chaw tsis muaj kev puas tsuaj, nws yog qhov zoo tshaj plaws los npog thaj tsam ntawm qhov khawb nrog daim kab xev npog.
2. Nrog kev pab los ntawm ib tug cwj mem, ib qho xim muaj pes tsawg leeg yog siv. Yog tias tsis muaj, ces khawb yog ua tib zoo sau cov xim nrog cov tshuaj txhuam hniav zoo tib yam, tab sis tsis yog rau saum npoo, tab sis kom muaj chaw rau kev siv cov polishing muaj pes tsawg leeg.
3. Tom qab cov xim tau qhuav tag, polishing yog ua raws li tau piav qhia saum toj no.

3M Scratch thiab Swirl Remover txoj kev tshem tawm cov khawb tau txais kev tshuaj xyuas zoo heev, uas tsis tas yuav xaiv cov xim tsim nyog. Qhov tseem ceeb, qhov sib xyaw no me ntsis dissolves cov xim nyob ib ncig ntawm kos thiab sau rau hauv. Tom qab polishing, qhov kev puas tsuaj yuav luag tsis pom.

Yog tias cov hniav tsis tau tsim cov hlau quav ("pob"), koj tuaj yeem sim maj mam nyem nws tawm ntawm sab hauv. Ua li no, siv levers lossis hooks yog tias muaj qhov chaw nres tsheb hauv lub cev los siv lub zog. Qee lub sij hawm me ntsis kev siv zog los yog ob peb lub teeb kais dej nrog lub mallet (rubber mallet) yog txaus kom ncaj cov hniav.)

Qee tus kws tsim khoom siv lub tsheb chambers (pob chambers) txhawm rau txhawm rau "kicker". Cov txheej txheem yog qub, tab sis feem ntau zoo heev. Lub koob yees duab yog muab tso rau hauv ib lub dent, them nrog cardboard los yog plywood pads kom tsis txhob tawg, los yog muab tso rau ntawm ib tug canvas cover. Thaum pumped nrog huab cua, nws tuaj yeem, los ntawm kev nce hauv ntim, ncaj cov hlau rau hauv qhov chaw.

Nws raug nquahu kom sim ua kom sov cov hniav nyob ib ncig ntawm lub voj voog nrog lub tshuab ziab plaub hau, thiab tom qab ntawd txias nws nrog cov kua roj carbon dioxide liquefied (hauv qhov xwm txheej hnyav, tsuas yog nrog daim ntaub ntub dej). Qee zaum qhov no ua rau muaj txiaj ntsig zoo heev.

Yog tias koj muaj lub tshuab nqus tsev nqus los yog lub tshuab nqus tsev ntawm koj qhov chaw pov tseg, ces qhov teeb meem tseem yooj yim dua los daws.

• Nws kuj pib nrog qhov siab tshaj plaws kos ntawm qhov yuav tsum tau kho. Yog tias ib qho ntawm cov stiffeners (struts lossis tav) puas lawm, koj yuav tsum pib nrog lawv.

• Smoothing thaj chaw wrinkled pib los ntawm cov npoo, maj mam txav mus rau qhov chaw. Tom qab nyem tawm cov dents loj, koj tuaj yeem mus rau qhov kev kho kom zoo ntawm cov geometry ntawm ib feem uas siv rauj thiab anvils rau straightening. Tej zaum koj yuav tau ua kom sov qhov chaw nyob ib ncig ntawm lub cheeb tsam raug ncaj; qhov no tuaj yeem ua tiav nrog lub tsev plaub hau tshuab.

• Qhov zoo ntawm anti-aliasing yog tas li tshawb xyuas thaum lub sijhawm ua haujlwm.

Tam sim ntawd ua ntej thov txheej txheej, qhov saum npoo yog degreased nrog ib qho hnyav.

Rau thawj txheej, coarse-grained putty nrog hardener yog siv. Thov sib npaug nrog roj hmab spatula. Tsis txhob sim tso saib ib feem geometry tam sim ntawd; ib txheej tuab tuaj yeem tawg thaum shrinkage. Nws yog ib qho tsim nyog yuav tsum tso cai rau cov txheej txheem kom qhuav thiab tom qab ntawd siv cov txheej txheem tom ntej. Qhov siab tshaj plaws ntawm cov ntawv thov putty, raws li txoj cai, yuav tsum tsis pub tshaj 1-2 hli.

Tom qab daim ntawv thov coarse-grained putty tau qhuav, qhov saum npoo ntawm ib feem yog ua tib zoo hauv av thiab sanded kom txog thaum qhov chaw puas tau txais cov duab uas xav tau. Tsuas yog tom qab kev sib tsoo ntawm qhov chaw thiab ua kom huv si los ntawm cov plua plav tawm tuaj yeem siv cov txheej txheej txheej txheej txheej txheej, uas yuav tsum npog tag nrho cov kev pheej hmoo me me thiab khawb.
