Sisitemu yo gushushanya ikoreshwa
01
Sisitemu isanzwe yo gutwikira irashobora kugabanwa ukurikije igifuniko, sisitemu ebyiri zo gutwikira (primer + top coat); sisitemu eshatu zo gutwikira (primer + igiciriritse giciriritse + ikote ryo hejuru cyangwa icyuma cya flash irangi / gutwikira urumuri rworoshye); sisitemu enye yo gutwikira (primer + igiciriritse giciriritse + ikote ryo hejuru + itwikiriye varish yoroheje, ibereye imodoka nziza kandi zisabwa cyane).
Mubisanzwe, ibisanzwe ni sisitemu yo gutwikisha ibintu bitatu, ibisabwa byo gushushanya umubiri wimodoka ndende, bisi nu modoka yimodoka yubukerarugendo, cab yikamyo muri rusange ikoresha sisitemu yo gutwikira.
Ukurikije uko byumye, birashobora kugabanywa muri sisitemu yo kumisha hamwe na sisitemu yo kwumisha. Sisitemu yo kumisha irakwiriye kubyara umurongo rusange; sisitemu yo kwumisha ikwiranye nicyiciro gito cyo gusiga amarangi yimodoka hamwe no gushushanya umubiri munini udasanzwe.
Igikorwa rusange cyo gutwikira bisi nini na sitasiyo ya wagon umubiri niyi ikurikira:
Mbere yo kuvura (kuvanaho amavuta, gukuramo ingese, gusukura, guhinduranya ameza) fosifati yoza isuku yumye primer yumye putty coarse scraping (yumye, gusya, guhanagura) ibishishwa byiza (byumye, gusya, guhanagura) mubitambaro (byumye, gusya, guhanagura) kwambara (gukama vuba, gukama, gusya, guhanagura) irangi ryo hejuru (ryumye cyangwa igipfukisho) gutandukanya amabara (gukama)
Uburyo bwo kuvura imbere
02
Kugirango ubone igifuniko cyiza, kwitegura hejuru yubuso mbere yo gushushanya byitwa gusiga irangi. Kuvura imbere ni ishingiro ryibikorwa byo gutwikira, bigira ingaruka zikomeye kumiterere yububiko bwose, cyane cyane nko gusukura hejuru (gukuramo amavuta, gukuramo ingese, gukuramo ivumbi, nibindi) no kuvura fosifati.
Hariho uburyo bwinshi bwo gusukura hejuru:
. kogesha hamwe na 320-400 sandpaper hejuru ya FRP, hanyuma usukure hamwe na solge organic kugirango ukureho firime; ingese y'umuhondo hejuru yumubiri wimodoka igomba guhanagurwa na acide fosifori kugirango irebe ko igifuniko gifite imbaraga zo kurwanya ruswa kandi gifatanye neza hejuru yikibiriti.
. Ubuvuzi budasanzwe bwo kuvura ibice byicyuma kugirango tunoze imbaraga zo guhuza firime yamabara na substrate.
. Kuvura fosifate bifite inshinge zose hamwe no kwibiza. Ifu yoroheje ya zinc umunyu wihuse wo kuvura fosifora, misa ya fosifori ni 1-3g / m, membrane ifite uburebure bwa 1-2 μ m, ubunini bwa kirisiti ni 1-10 μ m, irashobora guterwa nubushyuhe buke 25-35 ℃ cyangwa ubushyuhe bwo hagati 50 -70 ℃.

1. Shira primer
Ipitingi ya primer niyo shingiro ryububiko bwose, kandi imbaraga zo guhuza hamwe no gukumira ruswa yo gutwikira ibinyabiziga nicyuma bigerwaho ahanini nayo. Primer igomba gutoranywa hamwe no kurwanya ingese zikomeye (spray yumunyu 500h), gufatana cyane na substrate (irashobora guhuza nibikoresho bitandukanye bya substrate icyarimwe), guhuza neza hamwe no gutwikisha hagati cyangwa ikote, ibikoresho byiza byo gutwika (ingaruka 50cm, gukomera 1mm, gukomera 0.5) gutwikira nka primer.
Ukoresheje uburyo bwo gutera akayaga (birashobora kandi guhitamo umuvuduko mwinshi utarinze gutera gaz) gutera priming, urashobora gukoresha uburyo butose bwo gukoraho ndetse no gutera imiyoboro ibiri, ubwubatsi bwubwubatsi 20-30s, buri intera ya 5-10min, nyuma yo gutera flash 5-10min mumatanura. , primer yumye firime yumubyimba 40-50 μ m.
2. Shushanya
Intego yo gusiba putty ni ugukuraho ibintu bidasanzwe byo gutwikira.
Puputty igomba gusibanganywa kumurongo wumye wa primer yumye, ubunini bwikibiriti muri rusange ntiburenga 0.5mm, hagomba gukoreshwa uburyo bushya bwo gusiba ahantu hashya. Ubu buryo bworoshye gukora ahantu hanini ho gushira, hashingiwe ku kutagira ingaruka ku musaruro, birasabwa ko buri kintu gisakara kigomba gukama no gusukwa neza, hanyuma ugasiba igikurikira gikurikira, ugashyiramo gusiba inshuro 2-3 nibyiza, ubanza gusibanganya umubyimba hanyuma hanyuma ugasiba neza, kugirango uzamure imbaraga zurwego rushyizweho kandi urusheho kunoza uburinganire.
Ukoresheje uburyo bwo gusya imashini gushira, guhitamo sandpaper ya 180-240 mesh.
3. Shira muri spray
Ukoresheje uburyo bwo gutera spatique cyangwa uburyo bwo gutera akayaga, gutera muri kote, birashobora kunoza amabuye yo kwifata, kunoza imiterere hamwe na primer, kunoza uburinganire nuburinganire bwubuso butwikiriwe, kugirango tunonosore ibyuzuye kandi bigaragaze neza irangi ryo hejuru. .
Hagati yo gutwikira muri rusange itose itose ikomeza gutera inshuro ebyiri, ubwubatsi bwubwubatsi ni 18-24s, buri ntera ya 5-10min, flash 5-10min mu ziko, ubunini bwikigereranyo cyo hagati ya firime yumye ni 40-50 μ m.
4. Shira irangi
Ukoresheje uburyo bwo gutera spatique cyangwa uburyo bwo gutera ikirere, gutera amarangi hejuru yimodoka, birashobora gutuma ikirere kirwanya ikirere, kugaragariza ibishashara no kurabagirana kwa firime nziza.
Bitewe nubwinshi bwimashini zubaka, ibisobanuro, uburemere bwimashini yose, ibice binini, muri rusange ukoresheje uburyo bwo gutera amarangi.
Ibikoresho byo gusasa birimo imbunda zo mu kirere, umuvuduko mwinshi utagira umuyaga utera imbunda, imbunda yo mu kirere ifasha imbunda n’imbunda ya static spray. Imbunda ya spray yo mu kirere ikora neza yimbunda yo mu kirere iracyari hasi (hafi 30%), imbunda yo mu kirere y’umuvuduko mwinshi itesha irangi, ibisanzwe biranga umwanda w’ibidukikije byombi birakomeye, ku buryo byahoze kandi bisimburwa na ikirere cyafashaga gutera imbunda nimbunda ya electrostatike.
Kurugero, uruganda rwa mbere rwimashini zubaka ku isi ——— Isosiyete ya Caterpillar yo muri Amerika ikoresha imbunda ya spray ifashwa n’umwuka mu gutera, kandi hood hamwe n’ibindi bikoresho bitwikiriye isahani ikoresha imbunda ya static spray. Ibikoresho byo gusiga imashini zubaka mubisanzwe bifata icyumba cyo gusiga amarangi cyamazi meza.
Ibice bito n'ibiciriritse birashobora kandi gukoresha icyumba cyo gusiga amarangi y'amazi cyangwa nta cyumba cyo gusiga amapompo, icyambere gifite imikorere yateye imbere, icya nyuma ni ubukungu, cyoroshye kandi gifatika. Bitewe nubushyuhe bunini bwimashini zose zububiko hamwe nibice, kumisha igipfundikizo cyacyo cyo kurwanya ingese muri rusange bifata uburyo bwo kumisha uburyo bwo guteka hamwe no guhumeka ikirere. Inkomoko yubushyuhe irashobora guhuzwa nuburyo bwaho, hitamo amavuta, amashanyarazi, amavuta ya mazutu yoroheje, gaze gasanzwe na gaze ya peteroli.
Uburyo bwo gutwika ibinyabiziga bufite imiterere yabyo kandi bushimangira ukurikije ubwoko bwimodoka:
. ibindi bice, nk'imodoka n'ikadiri, biri munsi ya kabine.
(2) Hariho itandukaniro rikomeye hagati yo gushushanya bisi namakamyo. Umubiri wa bisi urimo umukandara, skeleton, imbere yimodoka nubuso bwinyuma bwumubiri, muribwo hejuru yumubiri hejuru. Ubuso bwinyuma bwumubiri wimodoka ntibisaba gusa kurinda no gushushanya neza, ahubwo bufite ahantu hanini ho gutera, indege nyinshi, amabara arenze abiri, kandi rimwe na rimwe ikarito yimodoka. Kubwibyo, igihe cyubwubatsi ni kirekire kuruta ikamyo, ibisabwa byubwubatsi birarenze ikamyo, kandi inzira yo kubaka iragoye kuruta ikamyo.
. Igipfukisho cyacyo cyo hejuru ni urwego rwa mbere rwibishushanyo mbonera, bifite isura nziza, igaragara nk'indorerwamo cyangwa ubuso bworoshye, nta mwanda mwiza, gukuramo, kuvunika, iminkanyari, kubira ifuro n'inenge zigaragara, kandi bigomba kugira imbaraga zihagije zo gukanika.
Igipfundikizo cyo hasi ni urwego rwiza rwo kurinda, rugomba kugira ingese nziza kandi irwanya ruswa kandi ifatanye cyane; igice cyangwa byose byashyizwe hamwe no gufatana neza hamwe nimbaraga zo mumashini ntizishobora kubora cyangwa kugwa mumyaka myinshi.
