Painting ndondomeko ndondomeko ntchito
01
Dongosolo lopaka utoto wamba limatha kugawidwa molingana ndi zokutira, njira ziwiri zokutira (primer + top coat); Njira zitatu zokutira (zoyambira + zapakati + malaya apamwamba kapena utoto wachitsulo wonyezimira / chivundikiro cha varnish); makina opaka anayi (zoyambira + zapakati + chovala chapamwamba + chophimba cha varnish chowala, choyenera magalimoto apamwamba okhala ndi zofunikira zokutira zapamwamba).
Nthawi zambiri, zofala kwambiri ndi atatu ❖ kuyanika dongosolo, kukongoletsa zofunika thupi mkulu galimoto, basi ndi alendo galimoto thupi, galimoto kabati zambiri ntchito atatu ❖ kuyanika dongosolo.
Malinga ndi kuyanika, akhoza kugawidwa mu kuyanika dongosolo ndi kudziwumitsa dongosolo. Dongosolo lowumitsa ndi loyenera kupanga mzere wambiri wa msonkhano; makina owumitsa okha ndi oyenera kupanga gulu laling'ono la kujambula magalimoto ndi kujambula kwakukulu kwapagalimoto yapadera yamagalimoto.
Njira yokutira ya mabasi akulu ndi station wagon body ndi motere:
Kuchiza (kuchotsa mafuta, kuchotsa dzimbiri, kuyeretsa, kukonza tebulo) phosphating kuyeretsa koyambira kowuma kowuma (kupukuta, kupukuta, kupukuta) kupukuta bwino (kupukuta, kupukuta, kupukuta) mu zokutira (zowuma, kugaya, pukuta) kuvala (kuyanika msanga, kuuma, kupera, kupukuta) utoto wapamwamba (wouma kapena wophimba) kulekanitsa mtundu (kuyanika)
Front pamwamba mankhwala ndondomeko

Pofuna kupeza chophimba chapamwamba, kukonzedweratu kwa nsabwe za m'mimba musanayambe kujambula kumatchedwa mankhwala opangira utoto. Kuchiza kutsogolo pamwamba ndi maziko a ndondomeko yokutira, yomwe imakhudza kwambiri khalidwe la chophimba chonsecho, makamaka kuphatikizapo kuyeretsa pamwamba (kuchotsa mafuta, kuchotsa dzimbiri, kuchotsa fumbi, etc.) ndi chithandizo cha phosphating.
Pali njira zingapo zoyeretsera pamwamba:
(1) Tsukani ndi sopo wotentha ndikutsuka ndi zosungunulira za organic kuchotsa mafuta; kupukuta ndi 320-400 sandpaper pamwamba pa FRP, ndiyeno kuyeretsa ndi zosungunulira organic kuchotsa chochotsera filimu; dzimbiri lachikasu pamwamba pa thupi lagalimoto liyenera kutsukidwa ndi phosphoric acid kuonetsetsa kuti zokutira zili ndi kukana kwa dzimbiri komanso kumamatira bwino pamwamba pa zokutira.
(2) Mankhwala osiyanasiyana oyeretsedwa pamwamba pa zitsulo zokutidwa kuti apititse patsogolo kumamatira ndi kukana kwa dzimbiri kwa filimu ya utoto. Chithandizo chapadera chamankhwala chamagulu azitsulo kuti apititse patsogolo kuphatikiza kwa filimu ya utoto ndi gawo lapansi.
(3) Gwiritsani ntchito njira zamakina kuti muchotse zolakwika zamakina azinthu zokutira ndi kuuma kofunikira kuti mupange filimu yokutira. Chithandizo cha phosphate chimakhala ndi jekeseni wophatikizika komanso kumizidwa kofunikira. Woonda filimu zinki mchere mofulumira phospholation mankhwala, phospholated nembanemba misa ndi 1-3g / m, nembanemba ndi 1-2 μ m wandiweyani, galasi kukula 1-10 μ m, akhoza phospholated ndi otsika kutentha 25-35 ℃ kapena sing'anga kutentha 50 -70 ℃.

1. Utsi woyambira
Kupaka koyambira ndiye maziko a zokutira zonse, ndipo kuphatikiza mphamvu ndi kupewa dzimbiri kwa zokutira zamagalimoto ndi zitsulo zimatheka ndi izi. Woyamba ayenera kusankhidwa ndi amphamvu dzimbiri kukana (mchere kutsitsi 500h), amphamvu adhesion ndi gawo lapansi (angathe atengere zosiyanasiyana gawo lapansi zipangizo pa nthawi yomweyo), kuphatikiza bwino ndi sing'anga ❖ kuyanika kapena topcoat, ❖ kuyanika zabwino makina katundu (zokhudza 50cm); kulimba 1mm, kuuma 0.5) zokutira ngati zoyambira.
Kugwiritsa ntchito mpweya kupopera njira (akhozanso kusankha kuthamanga kwambiri popanda kupopera mpweya) kupopera mbewu mankhwalawa priming, angagwiritse ntchito chonyowa kukhudza chonyowa njira ngakhale utsi njira ziwiri, kumanga mamasukidwe akayendedwe 20-30s, iliyonse imeneyi 5-10min, pambuyo kupopera mbewu mankhwalawa kung'anima 5-10min mu uvuni. , choyambira youma filimu makulidwe 40-50 μ m.
2. Scratch putty
Cholinga cha scraping putty ndi kuthetsa kusakhazikika kwa zinthu zokutira.
Puputty iyenera kukwapula pagawo lowuma loyambira, makulidwe a zokutira nthawi zambiri sapitilira 0.5mm, njira yatsopano yokololera ya putty iyenera kugwiritsidwa ntchito. Njirayi ndiyosavuta kupanga malo ambiri a putty, potengera kuti sizikhudza kupanga, akuti scraping putty iyenera kuwumitsidwa ndikupukutidwa, kenako ndikupukuta chotsatira, putty kuti scrape nthawi 2-3. Ndi yabwino, kukwapula koyamba kokhuthala kenako kukwapula kopyapyala, kuti muwonjezere mphamvu ya putty wosanjikiza ndikuwonjezera kusalala kwake.
Pogwiritsa ntchito makina akupera putty, sandpaper kusankha 180-240 mauna.
3. Ikani mu sprayer
Kugwiritsa ntchito malo amodzi kupopera mbewu mankhwalawa kapena mpweya kupopera njira, kupopera mbewu mankhwalawa mu ❖ kuyanika, akhoza kusintha mwala kukana ❖ kuyanika, kusintha adhesion ndi zoyambira, kusintha flatness ndi kusalala kwa pamwamba TACHIMATA, kusintha chidzalo ndi kusinkhasinkha mwatsopano wa utoto pamwamba. .
Sing'anga ❖ kuyanika ambiri chonyowa chonyowa mosalekeza kupopera mbewu mankhwalawa, kumanga mamasukidwe akayendedwe ndi 18-24s, aliyense imeneyi 5-10min, kung'anima 5-10min mu uvuni, makulidwe a sing'anga ❖ kuyanika youma filimu makulidwe ndi 40-50 μ m.
4. Utsi penti
Pogwiritsa ntchito kupopera mankhwala osasunthika kapena kupopera mpweya, kupopera mbewu mankhwalawa pamwamba pagalimoto, kumatha kupanga kukana kwanyengo, kuwunikira mwatsopano komanso kunyezimira kwa filimu yabwino kwambiri ya utoto.
Chifukwa cha mitundu yosiyanasiyana ya makina omanga, mawonekedwe, kulemera kwa makina onse, magawo akulu, omwe amagwiritsa ntchito kupopera mbewu mankhwalawa popenta.
Zida zopopera zili ndi mfuti yopopera mpweya, mfuti yopopera yopanda mpweya, mfuti yopopera mpweya komanso mfuti yopopera yosasunthika. Mpweya wopopera mfuti wa mpweya wopopera mpweya ndi wotsika (pafupifupi 30%), mfuti yopopera mpweya wopopera mpweya imawononga utoto, mawonekedwe odziwika bwino a kuipitsidwa kwachilengedweku ndi koopsa kwambiri, motero zakhala zikuchitika ndipo zikusinthidwa. mfuti yothandizira mpweya ndi mfuti yonyamula ma electrostatic jakisoni.
Mwachitsanzo, kampani yoyamba padziko lonse yopanga makina omanga ——— Kampani ya Caterpillar American imagwiritsa ntchito mfuti yopopera mothandizidwa ndi mpweya popopera mbewu mankhwalawa, ndipo chivundikiro ndi mbali zina zotchingira mbale zopyapyala zikugwiritsa ntchito mfuti yopopera yosasunthika. Zida zopenta zamakina omangira nthawi zambiri zimatenga chipinda chopenta chamadzi chopopera chapamwamba kwambiri.
Zigawo zing'onozing'ono ndi zapakati zingagwiritsenso ntchito chipinda chojambulira chinsalu chamadzi kapena chipinda chopanda chopopera, choyambiriracho chili ndi ntchito zapamwamba, zomalizazi ndizochepa, zosavuta komanso zothandiza. Chifukwa cha kutentha kwakukulu kwa makina onse a uinjiniya ndi magawo ake, kuyanika kwa zokutira zake zotsutsana ndi dzimbiri kumatengera njira yowumitsa yophika yunifolomu ndi kutulutsa mpweya wotentha. Gwero la kutentha likhoza kusinthidwa malinga ndi momwe zinthu zilili, sankhani nthunzi, magetsi, mafuta a dizilo, gasi wachilengedwe ndi gasi wamafuta amafuta.
Njira yokutira yamagalimoto ili ndi mawonekedwe ake komanso kutsindika malinga ndi mitundu yosiyanasiyana yamagalimoto:
(1) Mbali yayikulu yophimba ya galimotoyo ndi kabati yakutsogolo yokhala ndi zofunika kwambiri zokutira; mbali zina, monga chonyamulira ndi chimango, ndizotsika kuposa kabati.
(2) Pali kusiyana kwakukulu pakati pa kujambula kwa basi ndi galimoto. Thupi la basi limaphatikizapo girder, mafupa, mkati mwa galimoto ndi kunja kwa thupi, komwe kunja kwa thupi kumakhala kokwezeka. Kunja kwa thupi la galimoto sikumangofuna chitetezo chabwino ndi kukongoletsa, komanso kumakhala ndi malo akuluakulu opopera mankhwala, ndege zambiri, mitundu yoposa iwiri, ndipo nthawi zina riboni yagalimoto. Choncho, nthawi yomangayi ndi yaitali kuposa galimoto, zofunikira zomanga zimakhala zapamwamba kuposa galimotoyo, ndipo ntchito yomangayi imakhala yovuta kwambiri kuposa galimotoyo.
(3) Magalimoto ndi ngolo zing'onozing'ono, kaya zokongoletsa pamwamba kapena pansi pachitetezo ndizokwera kuposa mabasi akuluakulu ndi zofunikira zamagalimoto. Kupaka kwake pamwamba ndi kwa msinkhu woyamba wa kukongola kokongola, ndi maonekedwe okongola, owala ngati galasi kapena yosalala pamwamba, opanda zonyansa zabwino, abrasions, ming'alu, makwinya, thovu ndi zowoneka bwino, ndipo ayenera kukhala ndi mphamvu zokwanira zamakina.
Kupaka pansi ndi chitetezo chabwino kwambiri, chomwe chiyenera kukhala ndi dzimbiri komanso kukana kwa dzimbiri komanso kumamatira mwamphamvu; tsankho kapena putty zonse ndi adhesion wabwino ndi mkulu mawotchi mphamvu sadzachita dzimbiri kapena kugwa kwa zaka zingapo.
