Ukuhlaziywa kwezingubo zemoto nezendlalelo zopende
Okuqukethwe
Lapho uhambisa imoto emgwaqweni, abantu abaningi babheka ukwakheka kwayo nombala wayo. Bambalwa abantu abacabanga ukuthi kungani lo mbala ubukeka umuhle kangaka, ngoba kunezinye izingqimba zepende, ezinemisebenzi ethile ezovikela insimbi emiphumeleni yama-agent asemkhathini futhi izovimbela ukuthi upende ungadabuki.
Ngakho-ke, ngombono wokulungisa, kubalulekile ukwazi ukuthi iyiphi indima edlalwa upende, ukumboza noma ukuqeda, kodwa kubalulekile ngokulinganayo ukucacisa indima ethile edlalwa upende we-undercoat, ikakhulukazi lapho kudingeka ukulungiswa. Kodwa qala ufunde indlela ukususa umnyango wangaphambili Vaz-21099uma udinga ukushisela i-rack, kodwa awekho amathuluzi afanelekile esandleni.
Izendlalelo zokupenda zemoto
Ngaphambi kokufaka kuhlu izingqimba zokupenda ezisetshenziselwa imoto, kufanele kuqashelwe ukuthi kukhona umehluko phakathi kwengxenye yangaphandle yengubo naleyo esetshenziselwa ingaphakathi. Lokhu kwehlukaniswa kungenxa yenqubomgomo yokwehlisa izindleko futhi kwenziwa ngabakhiqizi bezimoto abafike kubo okuthi lolu hlobo lokuqeda alusetshenziswanga ukuqeda izinto ezithile zesakhiwo. Ngaphezu kwalokho, ngokuya ngesisekelo sendaba, izingqimba ezisetshenzisiwe noma ukumbozwa kopende nakho kuyahluka.
Ngokwalokhu kuguquka kokugcina, leli thebula elilandelayo likhombisa ukumbozwa okuvame kakhulu nezendlalelo zokupenda zento ngayinye kulezi:
Insimbi | Aluminium | Ipulasitiki |

Ukuhlaziywa kwezingqimba zokumboza nopende
Izingubo zokulwa nokugqwala
Njengoba igama layo likhombisa, kungumkhiqizo ohlinzeka ngezinga elisha lokuvikelwa engxenyeni yensimbi ephethwe ukuyivikela ekwakheni i-oxidation yamakhemikhali nokugqwala. Lokhu kuvikelwa kwenziwa ngqo ngumhlinzeki wensimbi.
Izindlela zokuvikela ezisetshenziswa embonini yezimoto:
- Idiphu Hot lashukumisa - insimbi efakwe kwisisombululo se-zinc ehlanzekile noma ama-alloys e-zinc ngensimbi (Zn-Fe), i-magnesium ne-aluminium (Zn-Mg-Al) noma i-aluminium kuphela (Zn-Al). Insimbi ibe isiphathwa ngokushisa kwe-slop ukuze insimbi isabele ne-zinc ukuze ithole ukunamathela kokugcina (Zn-Fe10). Lolu hlelo lusiza izendlalelo eziminyene futhi lumelane nomswakama.
- Plating zinc Electrolytic insimbi icwiliswa ethangini eligcwele isisombululo se-zinc esimsulwa, isixazululo sixhunywe kubaqhubi bakagesi, i-positive (anode) nensimbi ixhunywe kwesinye isigxobo (i-cathode). Lapho kuhlinzekwa ugesi futhi kuthintwa izintambo ezimbili ze-polarity ehlukene, kutholakala umphumela we-electrolytic, oholela ekubekeni i-zinc ngokungaguquguquki nangokufanayo phezu kobuso bensimbi, obuqeda isidingo sokufaka ukushisa ensimbi. Le ngubo ayikuvumeli ukuthola izingqimba zobukhulu obunjalo, futhi inokumelana okuncane ezindaweni ezonakalisayo.
- Ukukhanya: lokhu kungukuvikelwa kwensimbi yensimbi ne-boron, equkethe ukucwilisa le nsimbi kubhavu oshisayo oqukethe i-90% aluminium ne-10% silicon. Le nqubo ifaneleka ngokukhethekile kulezo zinsimbi ezinyathelisiwe ezishisayo.
Phosphating futhi galvanizing
Ukwenza i-phosphating, umzimba ucwiliswa endaweni eshisayo (engaba ngu-50 ° C), equkethe i-zinc phosphate, i-phosphoric acid kanye ne-additive, i-catalyst ephendula ngobuso bensimbi ukudala ungqimba olunezinsika oluncane olukhuthaza ukunamathela kwalezi zingqimba ezilandelayo. Ngokwengeziwe inikeza ukuvikelwa ekugqolweni nasekugqolweni.
Ukugcoba kwenziwa ngenxa yesidingo se-passivation ukugcwalisa ama-pores akhiwe futhi kuncishiswe ukukhahlamezeka kwendawo. Ngale njongo, kusetshenziswa isixazululo se-aqueous esine-trivalent chromium.
ICataphoresis Primer
Lokhu kungenye yengubo ye-epoxy anti-corrosion esetshenziswa ngemuva kwe-phosphating kanye ne-passivation. Kuqukethe ukufaka lolu ungqimba ngenqubo kubhavu osika ugesi onesisombululo samanzi akhethiwe, i-zinc, i-resin nezingulube. Ukunikezwa kwamandla kagesi kusiza i-zinc nezingulube ukuthi zihehwe insimbi, zinikeze ukunamathela okuhle kakhulu kunoma iyiphi ingxenye yemoto.
Izendlalelo zopende zokugqwala ezichazwe kuze kube manje ziyizinqubo ezihlukile zokukhiqiza, yize kukhona okufana nama-electro-primer noma okunye okufaka esikhundleni njengama-phosphating primers, resin epoxy noma "wash-primers" avumela ukusetshenziswa kwezingubo zokulwa nokugqwala.
Oku-Anodized
Le yinqubo ye-electrolytic ebhekiswe ezingxenyeni ze-aluminium, okuholela kungqimba lokufakelwa nokusebenza okungcono. Ukugcizelela ingxenye ethile, kufanele kuxhunywe amandla kagesi ngemuva kokufakwa kwesixazululo kwisisombululo samanzi ne-sulfuric acid ezingeni lokushisa (phakathi kuka-0 no-20 ° C).
I-Adhesive primer
Lo mkhiqizo, ihlose ukwenza ngcono ukunamathela kwezendlalelo ezingezansi, okunzima ukunamathela kupulasitiki ne-aluminium. Ukusetshenziswa kwabo ekulungiseni ukulungisa kubalulekile ukufeza le nhloso nokuqinisekisa ukuqina kwengubo esetshenzisiwe.
Ukuqiniswa
Ukuqinisa kabusha i-primer esetshenziswa kuwo womabili amafektri nomsebenzi wokulungisa, owenza le misebenzi elandelayo:
- Kuvikela i-cataphoresis.
- Kuyisisekelo esihle sokuqeda izinto.
- Igcwalisa futhi ifake ama-pores amancane kanye nokungapheleli okusele ngemuva kokufaka isihlabathi ku-putty.
Izimpawu
Lolu hlobo lokumboza lusetshenziswa kuphela kulezo zingxenye zemoto ezinomthungo noma uphawu. Umsebenzi wama-sealant ukuqinisekisa ukuqina endaweni yomhlangano, ukuvimbela ukuqongelela umswakama kanye nokungcola emajoyini, nokukhawulela ukungena komsindo ngaphakathi kwekhabethe. Ngaphezu kwalokho, zithuthukisa ukubukeka kwejoyinti, zisiza ekutholeni umphumela wobuhle obengeziwe, futhi zinezinto zokulwa nokugqwala namandla okumunca amandla uma kwenzeka kushayisana.
Ububanzi bama-sealants buhlukahlukene futhi kufanele bufanele isicelo.
Ukumbozwa kwama-anti-gravel
Lawa ngamapende afakwa ngaphansi kwemoto ukuze avikeleke ezimweni ezinzima zemvelo ezivezwa kuzo kulezi zindawo (ukuchayeka ukungcola, usawoti, imvula, isihlabathi, njll.). Lona umkhiqizo wokunamathisela owenziwe ngesisekelo se-synthetic resins kanye nama-rubber, abonakala ngokushuba okuthile kanye nokuqina angasetshenziswa ekulungiseni ngezibhamu ezikhethekile noma emaphaketheni e-aerosol.
Imvamisa, le ngubo ikhona esitezi semoto, imengamo yamasondo, izigaxa zodaka nezihlalo zezinyawo ngaphansi komnyango, nasezimbanjeni.
Iyaqeda
Opende bokugcina bawumkhiqizo wokugcina wayo yonke inqubo yokumboza nokuvikela, ikakhulukazi ekusikeni komzimba. Banikeza ukubukeka kwemoto, futhi ngaphezu kwalokho benza umsebenzi wokuvikela. Ngokuvamile zihlukaniswa kanje:
- Ama-Paints noma ama-monolayer systems: lawa amapende ahlanganisa yonke into endaweni eyodwa. Lolu uhlelo, indlela yesisebenzi sasefekthri evamile lapho kutholakala khona imibala eqinile kuphela. Umkhawulo ekukhishweni kwezinhlanganisela eziphilayo eziguquguqukayo, kanye nobunzima bokuthola imibala yensimbi, kanye nokudaya ngombala owodwa kuyibubi balezi zinhlobo zamapende.
- Izinhlelo zokupenda noma zokukhokha: kulokhu, imikhiqizo emibili iyadingeka ukuthola umphumela ofanayo nowohlelo lwe-monolayer. Ngakolunye uhlangothi, ngesisekelo se-bilayer, ungqimba lokuqala lunikeza umthunzi othile engxenyeni, futhi, ngakolunye uhlangothi, kukhona i-varnish enikeza ubuso bukhanye futhi ivikele isisekelo se-bilayer ezimweni zezulu. Uhlelo lwe-bilayer njengamanje luvame kakhulu ngoba luyasetshenziswa efektri ukukhiqiza imibala enemiphumela yensimbi neye-pearlescent.
Kulokhu, kufanele kuqashelwe ukuthi kungenzeka ukuthola isiphetho esihle esisuselwa emanzini, esenza sikwazi ukuhambisana ngokuphelele nomthetho okuQUKETHWE okuphansi wezinto eziyingozi eziyingozi, kanye nokusebenzisa izingulube ezahlukahlukene ukuthola noma imiphi imibala noma imiphumela ethile (imibala enemibala, insimbi, iparelecenti, umphumela unwidi, njll.).
Ngokufana ne-hairspray, lo mkhiqizo uhlinzeka ngamandla, ubulukhuni nokuqina okuphezulu kunezinhlelo ze-monolayer ezinganikeza. Isisekelo saso samakhemikhali singaba solvent noma aqueous futhi sivumele umbala okhanyayo weparele womphumela omuhle nokujula okukhulu kombala we-metallic-mother-of-pearl.
Iziphetho zokugcina
Izingxenye ezahlukahlukene zemoto zifakwe izendlalelo ezahlukahlukene eziyisisekelo nezokuqeda ukuvikela iziqhekeza nokukhuthaza ukunamathela phakathi kopende. Ngakho-ke, ulwazi lwezingqimba ezahlukahlukene zokumboza nopende ezihlanganisa ingxenye ethile yomzimba kuyisisekelo sokubuyiselwa kwawo futhi kufinyelelwe ukulungiswa kwekhwalithi ephezulu nokumbozwa okuqinile okuphinda izinqubo ezisetshenziswe efektri. Ngaphezu kwalokho, ukusetshenziswa kwemikhiqizo esezingeni eliphakeme nakho kunomthelela kulo mgomo.
