Yilwa ne-Underbody Corrosion nge-Sealant

Umzimba wemoto ungase ube muhle, kodwa okuphansi akunakunakwa. Ngisho noma imoto icwebezela ngopholishi, okungaphansi kusengalahleka ngokungenakulungiseka. Ukugqwala okuphansi kuwumbandela wokwehluleka wokuhlolwa kobuchwepheshe. Okuwukuphela kwento ehlinzeka ngokuvikeleka okuthembekile kwezembozo zamasondo, ama-sill kanye ne-underbody kusuka ekugqwaleni i-cavity coating kanye ne-sealant. Ngeshwa, azikho izinyathelo ezinikeza isisombululo esihlala njalo futhi ukuhlolwa ngezikhathi ezithile, ikakhulukazi ezimotweni ezindala, kuyadingeka. Lo mhlahlandlela umayelana nokuvala uphawu phansi (Am: primer) futhi uzokutshela konke okudingeka ukwazi mayelana nokuvala uphawu okuchwepheshile ukuze uvimbele ukugqwala.

Inhlanganisela engavumelekile

Izimoto zisakhiwe kakhulu ngamapaneli ensimbi. Azikho ezinye izinto ezinikeza ibhalansi ekahle yokumila okubandayo, amandla kanye nenani elifanele. Ukungalungi okuyinhloko kwamapaneli ensimbi yinsimbi yawo ephezulu. Lapho uthintana nomswakama - futhi esimweni esibi kakhulu - ngosawoti womgwaqo, insimbi iqala ukugqwala. Uma lokhu kungabonakali futhi kuqedwe ngesikhathi, ukugqwala kuzosakazeka kancane kancane.

I-Underseal iyasiza, kodwa hhayi kuze kube phakade

I-Underseal iyinamethi evikelayo, evame ukuqukatha itiyela, ekahle kakhulu ekuvaleni phansi. . Namuhla, ungqimba oluvikelayo lusetshenziswa ezimotweni ezintsha ngesikhathi sokwakhiwa, okuhlala iminyaka eminingana. I-underseal isetshenziswa kungqimba engu-½ mm. Into yerabha igcwalisa izimbobo zesihlabathi futhi ayiklwebhi. Ngokuhamba kwesikhathi, i-sealant ivame ukuma. Ngakho-ke, ngemva kweminyaka engaphezu kwengu-8, ungqimba oluvikelayo kufanele lubhekwe ngokucophelela. Uma kukhona ukuqhekeka noma ungqimba luyaxebuka, isinyathelo esisheshayo siyadingeka.

Ugibe olubizwa ngophawu oludala

Ngezinye izikhathi umswakama uzovala ijazi elidala le-primer. Uma amanzi anosawoti efika phakathi kwesendlalelo sokuzivikela kanye neshidi lensimbi, ngeke akwazi ukuphuma. Amanzi asele ensimbi abangela ukugqwala. Kulokhu, uphawu lwamafutha oludala lwenza okuphambene nenhloso yalo yasekuqaleni - esikhundleni sokuvikela ukugqwala, lukhuthaza ukwakheka kokugqwala.

Ukusetshenziswa nokuthuthukiswa kwesendlalelo esingezansi

Ngakho-ke, ukufafaza ungqimba lwe-dinitrol noma i-tektyl ​​kungqimba oludala lwe-sealant akusizi kakhulu. Ukuze kuvikelwe unomphela ingxenye engaphansi yemoto ekugqwaleni, ungqimba oludala lwe-sealant kufanele lukhishwe. Izindaba ezimbi ukuthi kunzima noma kuyabiza. Izindaba ezinhle ukuthi izindawo ezilimele kakhulu kuphela ezidinga ukwelashwa. Njengomthetho, lawa amaphethelo wemibundu noma ama-wheel arches. Ingaphezulu elivala ingxenye emaphakathi yomuntu ongaphansi ngokuvamile lihlala lifana kuyo yonke impilo yemoto.

Inqubo Yokususwa Kwesendlalelo Esingezansi

Kunezindlela ezintathu zokususa uphawu olungezansi:
1. Ukususwa mathupha nge-scraper nebhulashi lensimbi
2. Ukutubeka
3. Ukuqhunyiswa kwesihlabathi

Ukukhipha mathupha nge-scraper nebhulashi kunzima kakhulu futhi kulungele ikakhulukazi ukususa ukugqwala okuxekethile ezindaweni lapho izimbobo zibonakala khona. . Ukusetshenziswa kobuchwepheshe akusebenzi kangako lapha. Itiyela elibonakalayo lizovala amabhulashi ajikelezayo kanye ne-sandpaper ngokushesha okukhulu. Umsebenzi wezandla ozinzile iyona ndlela engcono kakhulu. Isibhamu sokushisa singenza umsebenzi ube lula kakhulu, ikakhulukazi ezindaweni okunzima ukufinyelela kuzo.

Ukutubeka kuwumkhuba wabafundi abazimisele ngokuzifundisa . Seluleka ngokuqinile ngokumelene nokudlala ngomlilo. Ngaphambi kokuthi wazi, ushise imoto yakho ngakho-ke igaraji lakho lonke.

Okokugcina, i-sandblasting iyindlela ethandwayo yokukhipha uphawu olungezansi. . Kunezindlela ezimbili ezihlukene ngokuyisisekelo: -lumayo и engathuvi . Lapho kuqhuma abrasive i-granular material idliswa phansi kwemoto kusetshenziswa umoya ocindezelweyo. Indlela eyaziwa kakhulu i-sandblasting, nakuba kunezinye iziqhumane ezimbalwa ezingenzeka: i-baking soda, ingilazi, ama-plastic granules, ama-nutshells nokuningi okuningi. Inzuzo yokuqhuma kwe-abrasive impumelelo eqinisekisiwe. Ungqimba oluvikelayo lususwa phansi ngokushesha nangempumelelo, futhi lushibhile kakhulu. Ububi bakhe inani lemfucuza elikhiqizayo. Ngaphezu kwalokho, ngenxa yokucindezela okukhulu kakhulu noma ukuhuzuka okungalungile, umugqa ophansi onempilo ungonakala. Enye indlela ephumelelayo kukhona izindlela zokuqhumisa ezingalimazi : Esikhundleni se-abrasive eqinile, ukuqhuma kweqhwa elomile kusebenzisa ama-granules e-carbon dioxide afriziwe agqabuka lapho eshaya ungqimba oluyisivikelo, alususe ngokuthembekile. Ngaphandle kwesendlalelo esidala sokuvikela, ukucutshungulwa kweqhwa elomile akumoshi futhi kuphephe ngokuphelele phansi. Enye indlela ukuhlanza amanzi anengcindezi ephezulu. Ukungafanele kulezi zindlela eziphumelela kakhulu yintengo yazo. Ukuqashwa kwe-ice blaster eyomile kubiza cishe. €100-300 (£175-265) ngosuku. Ngakho-ke, le ndlela ifaneleka ngokukhethekile ezimotweni ezisezingeni eliphezulu njengezimoto zezemidlalo zikanokusho noma izimoto zakudala. Ukuqhuma kweqhwa okomile okwenziwa ngumhlinzeki wesevisi ochwepheshe kungakubiza u-€500-1000.

Ukususwa kokugqwala

Ngaphambi kokufaka i-sealant entsha, umsebenzi othile wokulungiselela uyadingeka, ikakhulukazi ukususwa okuphelele kokugqwala okusele. I-scraper blade kanye nebhulashi zisebenza kakhulu, nakuba zisusa kuphela ukugqwala kwendawo evulekile. I-engeli grinder ikuvumela ukuthi usebenze ngokujula, kodwa ngesikhathi esifanayo uzibeka engcupheni yokugaya izinto ezinempilo. Ngakho-ke, sincoma ukusebenzisa isiguquli sokugqwala. Into isetshenziswa ngebhulashi lokupenda futhi kufanele ivunyelwe ukuthi ingene ngaphakathi. Lapho ukugqwala okubomvu sekuphenduke inqwaba yamafutha amnyama, kungamane kususwe nge-rag. Ngokusobala, i-rust hole welding kufanele ihlale ishiywe kubahlinzeki besevisi abangochwepheshe.

Okubaluleke kakhulu: degrease kanye tape

Ukumboza kudinga okufanayo nokupenda insimbi: pre-degrease ebusweni . Isihlanzi se-Silicone ibonakale ifaneleka kakhulu. Faka ungqimba oluvikelayo bese ulususa ngemva kokuthi lusebenzile. Ngemuva kwalokho, umzimba akufanele uhlangane nezinye izinto. Ukufutha akuvunyelwe I-Wd-40 noma amafutha angena. Uma kungenjalo, ungaqala inqubo yokwehlisa futhi.

Zonke izingxenye ezihambayo nezishisayo AKUMELE ziphathwe nge-sealant. Ngakho-ke, kunconywa ukumboza igiya lokuqondisa futhi ukhiphe ngephephandaba. I-Sealant ingase ivimbele ukunyakaza kwesiteringi. Uma ikhishwa, into idala ingozi yomlilo. Ngakho qiniseka ukuthi akukho okwenzekayo lapha! Tape ngaphandle kwefasitela phakathi. Le ndawo nayo idinga ukuvalwa.

Uphawu olusha

Ngemuva kokuqhunyiswa kwesihlabathi noma ukujikijela indawo engaphansi ibe ngamaphaneli angenalutho, kunconywa i-primer yokufafaza. Lokhu kuzovumela i-sealant ukuthi ibambelele kahle. Vele ufafaze ku-primer bese uvumela ukuthi yome.

I-Underseal okwamanje itholakala emathinini e-aerosol futhi kufanele ifuthwe ensimbi ungqimba 0,5 mm . Kulesi simo, akunconywa ukusebenzisa kakhulu. Ungqimba oluqinile oluvikelayo alusho lutho ngaphandle kokumosha izinto. Ungqimba olusha lokuvikela kufanele luvunyelwe ukuba lome amahora ama-4. Ngemuva kwalokho, i-tape ingasuswa. Ukubukeka kombundu manje kungapendwa ngombala wemoto. Ngemuva kokuqina, i-primer ingapendwa ngaphezulu.
