Ukuvuthela umzimba kuyivikela kanjani imoto ekugqwaleni?

Imoto ikhona inqobo nje uma inomzimba. Wonke amanye amayunithi anamathiselwe esisekelweni sawo futhi angashintshwa ngamazinga ahlukahlukene ezindleko zempahla. Yebo, futhi inombolo ye-VIN yemoto itholakala ezingxenyeni eziqinile kakhulu ezishiselwe esakhiweni sonke. Ungakwazi ukucekela phansi umzimba engozini embi kakhulu noma umane uwushiye ngaphandle kokuvikela ukugqwala. Ngakho-ke, ukunakwa okukhethekile kukhokhwa ezindleleni zokulwa nalesi simo esiyingozi.

Yini i-galvanizing

Indlela ephumelelayo eyaziwa ngokujwayelekile yokubeka umgoqo wokugqwala kube ukusetshenziswa kwe-zinc, ngamanye amazwi, izingxenye zensimbi ezikhangayo.

Le ndlela yokuvikela iqukethe izici ezimbili ezibalulekile:

1. ukutholakala kwe-zinc enamathela ezingxenyeni zomzimba kuvikela isisekelo sensimbi ekufinyeleleni komoya-mpilo namanzi, okuyizitha eziyinhloko zensimbi, uma ingekho ngesimo se-alloy engagqwali;
2. i-zinc yakha umbhangqwana we-galvanic ngensimbi, lapho, lapho amanzi evela, i-zinc eqala ukudliwa, ngokungafani nezinye izinsimbi zokumboza, ngokuphambene nalokho, isheshisa ukubhujiswa kwesisekelo.

Ngesikhathi esifanayo, i-zinc ayibizi kakhulu, futhi izinqubo zokusetshenziswa kwayo zithuthukiswe kahle kwezobuchwepheshe.

Izinzuzo nezingozi nebubi

I-Zinc coating ibonwa umphakathi wezimoto njengesivikelo esingcono kakhulu sensimbi yomzimba ngentengo ethengekayo. Uma isetshenziswa kanye nomsebenzi wokupenda wekhwalithi ephezulu (LKP), le ndlela inezinzuzo ezinhle:

• ukunamathela okuhle kwesisekelo sensimbi, i-zinc ngokwayo ayikhiphi ngenxa yokuxhumana ezingeni le-athomu;
• ukutholakala kokuvikela okuphindwe kabili, kokubili ukufakwa uphawu kanye ne-galvanic;
• ukumelana ne-zinc ngokwayo ekugqokeni kwamakhemikhali, ngoba iyingxenye yensimbi ekwazi ukudala ifilimu ye-oxide engagxili phezulu, kuyilapho ingasebenzi njenge-catalyst yokugqwala okuqhubekayo;
• izinhlobonhlobo zokusetshenziswa kobuchwepheshe;
• ukushibhile okuhlobene kwensimbi evikelayo.

Kukhona futhi ukungalungi:

• nakuba kungenjalo kakhulu, intengo yomzimba isakhuphuka;
• ukugqoka akumelani nokulimala kwemishini, ikakhulukazi, kubhujiswa ngesikhathi sokulungisa umzimba;
• inqubo yezobuchwepheshe iyinkimbinkimbi maqondana nokuvikelwa kwemvelo, ama-zinc compounds anobuthi;
• cishe akunakwenzeka ngale ndlela ukunikeza ukuvikelwa okuthembekile kwama-welds namanye amalunga ezitho zomzimba.

I-galvanization yenziwa kokubili ngokugcwele nayingxenye yomzimba, kucatshangelwa izinsongo ezivela ekugqwaleni kwezingxenye ezithinteka kakhulu, ikakhulukazi engxenyeni engezansi yemoto.

Izinhlobo ze-galvanizing yomzimba wemoto

Isifiso sokunciphisa izindleko zezinqubo zobuchwepheshe siphoqa abakhiqizi bezimoto ukuthi basebenzise izindlela zokusebenzisa i-zinc ezihlukile ekusebenzeni kahle.

Ukumboza imoto nge-zinc ngokuphelele, futhi ngisho nangendlela enokwethenjelwa, izinkampani ezimbalwa zingakwazi ukukhokhela. Imoto enjalo izomelana nokugqwala, kodwa cishe ngeke ithengise kahle ngenxa yentengo ephezulu.

Kuyashisa

Indlela yokwemboza yekhwalithi ephezulu kakhulu. Phakathi nenqubo yokukhiqiza, ingxenye icwiliswa ngokuphelele ku-zinc encibilikisiwe, ngemva kwalokho ungqimba oluqinile luhlala phezulu, luboshwe ngokuthembekile ensimbi.

Ukuvikela okunjalo kuhlala isikhathi eside, kunokwethenjelwa, futhi ngenxa yenani elikhulu lokunyathela, kuthatha isikhathi eside futhi kukwazi ngisho nokuqinisa kancane umonakalo omncane wemishini.

I-coating ihlala iminyaka eyi-10 noma ngaphezulu, okuvumela umenzi ukuthi anikeze isiqinisekiso sesikhathi eside ngokumelene ngomonakalo.

I-Electroplating

I-Zinc isetshenziswa ezingxenyeni nge-electroplating endaweni yokugeza ekhethekile ye-electrochemical. Ama-athomu athuthwa insimu kagesi futhi abambelele ngokuqinile phezulu.

Ngesikhathi esifanayo, izingxenye zishisa kancane futhi isisekelo sensimbi asilahlekelwa izici zayo zemishini. Indlela idinga ukuba khona kwesigaba se-galvanic esiyingozi emvelweni futhi idla inani elikhulu likagesi.

Kuyabanda

I-powder ekhethekile ixubene ku-primer efakwe emzimbeni ngokufafaza i-zinc powder enhle ebanjwe phezulu nge-primer layer.

Ukusebenza kuyangabazeka, njengoba ipheya ye-galvanic yezinsimbi ezidingekayo ukuze kuvikelwe ngempumelelo cishe ayikakhiwa. Noma kunjalo, ukuvikela okunjalo kunikeza umphumela othile futhi kuyasetshenziswa ngenkuthalo. Ukunikeza okuningi komthelela wokukhangisa kunokuvikela kwangempela ekugqwaleni.

Zincrometal

Indlela ifana neyangaphambili, ukugqoka kuhlanganisa izingqimba ezimbili zokuvikela kusuka kuma-corrosion inhibitors, ama-oxides kanye ne-zinc powder. Ihluke ngokunwebeka okukhuthaza ukuqina ngesikhathi sokukhiqizwa kwemoto.

Izinga lokuvikela liphakeme kunalelo elibandayo, kodwa alifinyeleli ekusebenzeni kahle kwezindlela ezishisayo kanye ne-galvanic. Ubuchwepheshe bokukhiqiza insimbi ye-zinc bungahluka, ngezinye izikhathi ukushisa nokuncibilika kwezingxenye ezisetshenzisiwe kusetshenziswa.

Ithebula lezindikimba zezimoto ezifaka ama-galvanizing yazo zonke izinhlobo

Ukukhiqizwa kwemikhiqizo eminingi kanye namamodeli wezimoto akuvumeli ohlwini olulinganiselwe ukukhombisa izindlela ezithile zemizimba ekhiqiza ama-galvanizing kanye nephesenti lezingxenye ezivikelwe emotweni.

Kodwa abakhiqizi basebenzisa ubuchwepheshe ngokuhlelekile, okwenza kube lula ukulinganisa izinga lokuvikelwa kwemikhiqizo ngayinye ezikhathini zamuva.

Impilo yesevisi yezingubo zokugqoka inganqunywa kuphela ngokwemibandela, ngoba incike kakhulu ezimweni zokusebenza.

Ekuhlolweni kohlobo, umonakalo olinganisiwe usetshenziswa emsebenzini womzimba, ngemva kwalokho ukusakazwa kokugqwala kuhlolwa emakamelweni okufuthwa ngosawoti, okuyizimo ezimbi kakhulu zensimbi yomzimba.

Ungahlola kanjani ukuthi umzimba wemoto unama-galvanized noma cha

Kungenzeka ukwenza lokhu ngendlela yocwaningo, kodwa kuyabiza, kudinga imishini ekhethekile kanye nokubhujiswa okuyingxenye kwezingubo. Ngakho-ke, indlela engcono kakhulu kungaba ukubhekisela kumadokhumenti embonini ukuze uthole imodeli ethile nolwazi lokusebenza oluvela ezibuyekezweni ze-inthanethi.

Kunezinsiza ze-inthanethi lapho kumodeli ngayinye ungathola khona ulwazi oluphelele.

Iwaranti yasefekthri yokungabikho komonakalo ingasho okuningi. Imvamisa, isikhathi esingaba yiminyaka eyi-12 sibonisa ikhwalithi ephezulu ye-zinc enamathela.

Ezimotweni esezike zasetshenziswa, ulwazi oluningi luphethe ukuphepha kwensimbi ezindaweni lapho umsebenzi wokupenda usuxetshuliwe. Ikhwalithi ephezulu ye-galvanizing ayivumeli ukugqwala ukuba kukhule ngisho nalapho kungekho i-varnish, upende kanye ne-primer.

Ungawenza kanjani amandla umzimba ngebhethri

Amabhethri asekhaya ajwayelekile angase abe nenkomishi ye-zinc, edlala indima yeyodwa yama-electrode. Umumo wale ngxenye ulungele ngokwanele ukudala into elula yokufaka ama-galvanizing. Ibhethri lemoto lisetshenziswa njengomthombo wamanje.

I-tampon yendwangu yenziwa eduze kwengilazi ye-zinc, efakwe i-phosphoric acid. Ungakwazi ukuncibilikisa ngaphambili i-zinc shavings encane elungiselelwe kusukela kubhethri efanayo kuwo. I-plus yebhethri ixhunywe ku-zinc, futhi i-minus isala emzimbeni wemoto.

Indawo okumele icutshungulwe kumele ihlanzwe ngokucophelela ngomshini kusukela emithonjeni emincane yokugqwala. Ngemuva kwalokho, i-swab ene-zinc icindezelwa ebusweni futhi ukusabela kuqala ukudlulisa i-zinc ensimbi yomzimba.

Inqubo yokwakheka kwe-coating ingabonwa ngokubonakalayo. Isendlalelo esiwumphumela ngeke sibe sibi kakhulu kunalokho esidalwe ekugezeni kwe-galvanic kwesitshalo.

I-galvanization yemoto ngebhethri.

Ekupheleni kwenqubo, izinsalela ze-asidi kufanele zisuswe ngesisombululo se-soda, ubuso kufanele bugezwe, bomiswe futhi bumbozwe ngezendlalelo zobuchwepheshe ze-primer, upende kanye ne-varnish.
