Amaphutha main lapho galvanizing umzimba imoto uwedwa
I-galvanizing umzimba wemoto ubuchwepheshe obuphumelela kakhulu bokulwa nokugqwala, okwenza kube nokwenzeka ukusebenzisa imoto ezimweni ezimbi kakhulu ngaphandle kwemiphumela. Yiqiniso, kubiza kakhulu. Ngakho-ke, akumangazi ukuthi abanikazi bezimoto ezisetshenzisiwe, ikakhulukazi lezo esezivele "ziqhakazile", bakhetha ukwenza le nqubo bebodwa. Kodwa ngokuvamile ngaphandle kwempumelelo enkulu. Kungani, futhi indlela yokufaka kahle imoto ekhaya, ingosi ye-AvtoVzglyad yatholakala.
Ngokuzilungisa umzimba, umshayeli onakekelayo ukhetha ukumboza insimbi engenalutho ngokuthile ngaphambi kokudweba. Futhi ukukhetha, njengomthetho, kuwela "entweni ene-zinc." Kodwa-ke, bambalwa abantu abaziyo ukuthi zimbalwa kakhulu izingoma ezikhethekile ze-galvanizing yangempela emakethe namuhla. Ezitolo, umnikazi wemoto uvame ukudayiswa ama-primers okuthiwa yi-zinc, kanye neziguquli zokugqwala ezimangalisayo zibe zinc. Konke lokhu akuhlangene kangako nokufaka amagalaji kwangempela.
AMAGAMA AKUHLE...
Ngakho-ke, kuvele "isiphazamisi" sokugqwala emotweni yakho. Ezimweni zezimoto ezisetshenzisiwe, isimo sivame kakhulu, ikakhulukazi endaweni yama-threshold nama-wheel arches. Imvamisa lezi zindawo zivele zihlanzwe ngokugqwala okuxekethile, kufakwe uhlobo oluthile lwesiguquli, i-primer nopende. Okwesikhashana konke kuhamba kahle, bese kuphuma ukugqwala futhi. Kanjani? Phela, ekulungiseleleni basebenzisa i-rust-to-zinc converter! Okungenani yilokho elikushoyo kulebula.
Eqinisweni, wonke amalungiselelo anjalo enziwa ngesisekelo se-orthophosphoric acid futhi umkhawulo ongenziwa ukubunjwa okunjalo yi-phosphate ebusweni, futhi lokhu kuzoba i-porous phosphating, eyogqwala esikhathini esizayo. Ifilimu ewumphumela ayikwazi ukusetshenziswa njengesivikelo esizimele - kuphela ukudweba. Ngakho-ke, uma upende usezingeni eliphansi, noma uvele uhlanjululwe, lolu ungqimba ngeke luvikele ekugqwaleni.
YINI ONGAYIKHETHA?
Emashalofini ezitolo zethu kukhona nezingoma zangempela zokuzikhandla, futhi kunezinhlobo ezimbili - zokugcoba okubandayo (le nqubo ibizwa nangokuthi i-galvanizing) kanye ne-galvanic galvanizing (imvamisa iza nakho kokubili i-electrolyte ne-anode), kodwa zibiza i-oda lobukhulu elibiza kakhulu kuneziguquli. Asazi ukuthatha galvanizing abandayo ku-akhawunti, ekuqaleni yasungulwa for enamathela izakhiwo metal, kuba engazinzile ukuze kuncibilika organic kanye umonakalo mechanical. Sinesithakazelo endleleni ye-galvanic yokusebenzisa i-zinc, kuyilapho konke okudingekayo kule nqubo kungenziwa ekhaya. Ngakho-ke, ingabe izodingeka ukuze kuqhume indawo yomzimba?
Ngaphambi kokuqhubeka, kufanele ukhumbule ukugcina izinyathelo zokuphepha lapho usebenza nama-reagents: sebenzisa imaski yokuphefumula, amagilavu enjoloba, izibuko, futhi wenze konke ukukhohlisa ngaphandle noma endaweni enomoya omuhle.
KANYE AMANZI ABILEYO
Isiteji sokuqala. Ukulungiswa kwensimbi. Indawo yensimbi akumele ingabi nokugqwala nopende. I-Zinc ayiwi phezu kokugqwala, futhi ngisho nangaphezulu ngopende. Sisebenzisa i-sandpaper noma imibhobho ekhethekile ku-drill. Kulula kakhulu ukubilisa ingxenye encane ku-10% (amagremu angu-100 e-asidi ku-900 ml wamanzi) isisombululo se-citric acid kuze kube yilapho ukugqwala kubhujiswa ngokuphelele. Bese ususa amafutha.
Isiteji sesibili. Ukulungiswa kwe-electrolyte ne-anode. Inqubo ye-galvanic galvanizing imi kanje. Kusixazululo se-electrolyte (i-electrolyte isebenza njengomqhubi wento), i-zinc anode (okungukuthi, plus) idlulisela i-zinc ku-cathode (okungukuthi, ukususa). Ziningi izindlela zokupheka ze-electrolyte ezintanta kuwebhu. Okulula kakhulu ukusebenzisa i-hydrochloric acid, lapho i-zinc ichitheka khona.
I-Acid ingathengwa esitolo se-chemical reagent, noma esitolo se-hardware. I-Zinc - esitolo esifanayo samakhemikhali, noma uthenge amabhethri ajwayelekile kasawoti bese ususa icala kuwo - lenziwe nge-zinc. I-Zinc kufanele incibilike kuze kube yilapho iyeka ukusabela. Kulokhu, igesi ikhishwa, ngakho-ke konke ukukhwabanisa, siphinda, kufanele kwenziwe emgwaqweni noma endaweni enomoya omuhle.
I-electrolyte yenziwa ibe nzima kakhulu ngale ndlela - ngamamililitha angama-62 amanzi sincibilikisa amagremu ayi-12 we-zinc chloride, amagremu angama-23 we-potassium chloride nama-3 amagremu we-boric acid. Uma kudingeka i-electrolyte eyengeziwe, izithako kufanele zengezwe ngokulinganayo. Kulula ukuthola ama-reagents anjalo esitolo esikhethekile.
KAHLE FUTHI UDABUKILE
Isiteji sesithathu. Sinendawo elungiselelwe ngokugcwele - insimbi ehlanzekile neyohlisiwe, i-anode esesimweni sekesi le-zinc elivela ebhethrini, i-electrolyte. Sigoqa i-anode nge-cotton pad, noma uboya bekotini, noma i-gauze egoqwe ngezingqimba eziningana. Xhuma i-anode ekuhlanganisweni kwebhethri lemoto ngentambo yobude obufanelekile, kanye nokukhipha emzimbeni wemoto. Gcoba uboya bekotini ku-anode ku-electrolyte ukuze igcwale. Manje, ngokuhamba kancane, siqala ukushayela phezu kwensimbi engenalutho. Kufanele ibe nesiphetho esimpunga kuyo.
LIPHI IPHUTHA?
Uma i-coating imnyama (ngakho-ke i-brittle futhi i-porous), khona-ke noma ushayela i-anode kancane, noma ukuminyana kwamanje kuphezulu kakhulu (kulokhu, susa i-minus ebhethri), noma i-electrolyte yomile uboya bekotini. Ingubo empunga efanayo akufanele isulwe ngozipho. Ubukhulu be-coating kuzodingeka bulungiswe ngeso. Ngale ndlela, kungafakwa izembatho ezingafika ku-15-20 µm. Izinga lokubhujiswa kwalo cishe lingama-microns angu-6 ngonyaka lapho lithinta imvelo yangaphandle.
Endabeni yengxenye, idinga ukulungisa ukugeza (ipulasitiki noma ingilazi) nge-electrolyte. Inqubo iyafana - kanye ne-anode ye-zinc, susa ingxenye eyisipele. I-anode kanye nengxenye eyisipele kufanele kufakwe ku-electrolyte ukuze bangathinti. Bese ubheka nje imvula ye-zinc.
Ngemuva kokufaka i-zinc, kuyadingeka ukugeza indawo yokufaka kahle ngamanzi ukuze ususe wonke ama-electrolyte. Ngeke kube yinto engadingekile ukususa amafutha futhi ngaphambi kokudweba. Ngale ndlela, izingxenye noma umsebenzi womzimba unganwetshwa impilo. Ngisho nokucekelwa phansi koqweqwe lwangaphandle lwepende kanye ne-primer, i-zinc ngeke isheshe igqwale insimbi ephathwayo.
