Ukhetho lonyango lomphezulu yingxaki yokuba wonke umyili ajongene nayo. Zininzi iindlela zokhetho lonyango olukhoyo, kwaye umyili ophezulu akufuneki uqwalasele uqoqosho kunye nokusetyenziswa koyilo, kodwa kukuthathela ingqalelo inkqubo yendibano kunye neemfuno zokusingqongileyo. Apha ngezantsi kukho intshayelelo emfutshane kwezinye iingubo eziqhelekileyo ezisetyenziselwa iingubo ezisetyenziswayo ezisekwe kule migaqo ingentla, ukubhekiswa ngabasebenzi abasebenza nge-hartener.
I-1. I-Electrogalvaning
I-Zinc yeyona isetyenziselwa ukuthantamisa kwendlela yokuthengisa. Ixabiso lixabiso eliphantsi, kwaye imbonakalo ilungile. Imibala eqhelekileyo ibandakanya umnyama noluhlaza. Nangona kunjalo, intsebenzo yayo yokulwa i-corrosion iphakathi, kwaye intsebenzo yayo ye-corrosion yeyona nto iphantsi phakathi kwe-zinc plates (i-cailing). Ngokubanzi, uvavanyo lokutshintshwa kwetyuwa elingathathi ntweni lwenziwe ngaphakathi kweeyure ezingama-72, kwaye iiarhente ezikhethekileyo zokutywina zisetyenziselwa ukuqinisekisa ukuba uvavanyo lokutshiza lungathathi cala luhlala ngaphezu kweeyure ezingama-200. Nangona kunjalo, ixabiso libiza kakhulu, elingamaxesha angama-5-8 lensimbi ye-gavanidited.
Inkqubo ye-electrogalvaning ithathelwa ingqalelo kwi-Hydrogen emfutshane, ngoko i-bolts ngaphezulu kweBanga le-10.9 ayizange iphathwe nge-GAGVAning. Nangona i-hydrogen ingasuswa isebenzisa i-oveni emva kokubekwa, ifilimu yokudluliselwa iya konakala kubushushu ngaphezulu kwe-60 ℃, ukususwa kwe-hydrogen kufuneka kwenziwe emva kokufakwa i-electroplast kwaye ngaphambi kokuba idlule. Oku kunento engasebenzi kakuhle kunye neendleko eziphezulu zokulungisa. Ngokwenyani, izityalo zemveliso ngokubanzi aziyisusi ngenyameko i-hydrogen ngaphandle kokuba igunyaziswe ngabathengi abathile.
Ukungqinelana phakathi kweTorque kunye namandla aqinileyo okuqinisa i-etywameni kuhlwempuzekile kwaye kungazinzisi, kwaye ngokubanzi akusetyenziswanga ukunxibelelana namacandelo abalulekileyo. Ukwenzela ukuphucula ukungaguquguquki komthwalo weTorque, indlela yokuthintela ukucoca i-toings emva kokuba ikwazi ukutshintsha kunye nokuphucula ukuguqulelwa komthwalo weTorque.
I-2. Phospheting
Umgaqo esisiseko kukuba i-josproting ihamba ngexabiso eliphantsi kune-gavaning, kodwa ukumelana nokunganyangeki kubi ngakumbi kune-gavaning. Emva kwe mpum, ioyile kufuneka isetyenziswe, kwaye ukuxhathisa i-corosions yayo kunxulumene ngokusondeleyo nokusebenza kweoyile esetyenzisiweyo. Umzekelo, emva kokusebenzisa phophant, ukusebenzisa ioyile echasene ne-anti jikelele kwaye kuqhuba uvavanyo lokutshiza i-verat kwiiyure ezili-10 ukuya kwezi-20. Ukusebenzisa ioyile yenqanaba eliphezulu le-Antic rist Light kunokuthatha iiyure ezingama-72-96. Kodwa ixabiso layo ngamaxesha angama-2-3 ayo yeoyile eguqukayo.
Zimbini iintlobo ezisetyenziswayo zePispfting yeTransteriners, ze-phosphoting phosphoting kunye ne-manganese. I-josprong esekwe kwi-jospheting inentsebenzo engcono ye-phosprose esekwe kwi-manganese phosphoting, kunye nePophant phosphothi esekwe kwi-manganesh inobuchasi obungcono kunye nokunganyangeki kune-zinc plates. Ingasetyenziswa kumaqondo obushushu asusela kwi-225 ukuya kwi-400 degrees fahrenheit (107-204 ℃). Ngakumbi ukunxibelelana nezinye izinto ezibalulekileyo. Njengokudibanisa iibhloko ze-rod kunye namandongomane eenjini, intloko ye-cylinde, ethengisa i-browwheel, ivili levili, amantshontsho, njl.
Amandla aphezulu e-bolts asebenzisa phosproting, enokuphepha imiba yokuyigcina i-hydrogen. Ke ngoko, i-bolts ngaphezulu kweBanga le-10.9 kwicandelo lemizi-mveliso lisebenzisa phosproveting yonyango.
I-3. I-oxidation (imnyama)
I-Blackeling + I-Oliiling yindlela ethandwayo yokuthandwa kwezamashishini ukuba ihamba kancinci kwaye ijongeka ilungile ngaphambi kokuselwa kweoyile. Ngenxa yokubeleka kwayo, iphantse ibekho nokubakho kokuthintela ukuthintela, kuya kuba njalo ngaphandle kweoyile. Nokuba ubukho beoyile, uvavanyo lokutshiza lwetyuwa lungahlala iiyure ezingama-3-5.
I-4. I-elektroplating
Ukubethwa kweCadmium kunengxaki yokunyanzelwa okungakumbi, ngakumbi kwiindawo zomoya wemomostic zaselwandle, xa kuthelekiswa nolunye unyango lomphezulu. Ixabiso lokunyanga inkcitho kwi-unyango lwenkqubo yenkqubo ye-electroplaium iphezulu, kwaye ixabiso layo limalunga ne-15 ukuya kwi-20 le-incroplay. Ke ayisetyenziswanga kumashishini ngokubanzi, kuphela kwiimeko ezithile. Abantu abakhethayo abasetyenziselwa iqonga lokuntywila kweoyile kunye ne-HNA.
I-5. I-Chromium
I-Chromium Ceating iZinzile kakhulu emoyeni, akukho lula ukutshintsha umbala kwaye ilahlekelwe luster, kwaye inobuqili obukhulu kunye nokunganyangeki okuhle nokunganyangeki kakuhle. Ukusetyenziswa kwe-chromium ukubekwa kwiindawo ezihlala kuzo zisetyenziselwa ukulungiselela iinjongo zokuhombisa. Kunqabile ukuba isetyenziswe kwimimandla yemizi-mveliso enemishini yokunyangeka ephakamileyo, njengoko i-chrome elungileyo ityholo ixabisa ngokulinganayo njengentsimbi engenasiseko. Kuphela kuxa amandla entsimbi engenasimo akonelanga, i-chrome idrotheners isetyenziswa endaweni yoko.
Ukuthintela ukuvela, ubhedu kunye ne-nickel kufuneka ifakwe kuqala ngaphambi kokubetha kwe-chrome. I-chromium cast inokumelana namaqondo obushushu aphezulu angama-1200 degrees Fahrede (650 ℃). Kodwa kukho nengxaki yokuthuka i-hydrogen, efanayo nakumbane.
I-6. I-Nickel Plate
Ikakhulu isetyenziswa kwiindawo ezifuna ukuntywila nokuntywila kunye nokuziphatha okuhle. Umzekelo, i-terminals ephumayo yeebhetri zemoto.
I-7. I-datvaning eshushu
I-dabvaning ye-DIP eshushu yi-thermal yokuthathwa kwe-zinc ifudumele i-wale. Ubungqingqwa bokuthinta phakathi kwe-15 ne-100 μ m. Kwaye akukho lula ukulawula, kodwa inesifo sokunganyangeka kakuhle kwaye ihlala isetyenziswa kubunjineli. Ngexesha lenkqubo ye-DIP eshushu, kukho ungcoliseko olukhulu, kubandakanya inkunkuma ye-zini kunye ne-zinc vapor.
Ngenxa yokukhathazeka okukhulu, kubangele ubunzima ekukhuliseni kwimigca yangaphakathi nangaphandle kwibala. Ngenxa yobushushu be-daip ye-dip-dip ye-dip, ayinakusetyenziselwa ukhangelo ngaphezulu kweBanga le-10.9 (340 ~ 500 ℃).
I-8. I-Zinc yokungenisa
Ukungeniswa kwe-zinc yindawo eqinileyo ye-metmelgalication ye-themil ye-thermal ye-chinc powder. Ukufana kwayo kulungile, kwaye umaleko ofanayo unokufumaneka kwimisonto kunye nemingxunya engaboniyo. Ubungqingqwa bokuthintela i-10-110 μ m. Kwaye impazamo inokulawulwa nge-10%. Intsebenzo yayo yokuxhuzula kunye nokulwa i-anti-corsion kunye neyona ndlela ilungileyo kwi-chinc iingubo (ezinjenge-electrogalvaning, i-DAP-DIP-dip ye-DACROMET). Inkqubo yayo yokuqhubela phambili yingcoliseko-ayinasona simahla.
I-9. Dacromet
Akukho nto yokufumana i-hydrogen emfutshane, kwaye i-trugrence yokulayisha i-Torttenction Intsebenzo ilungile. Ngaphandle kokuqwalaselwa kweChromium kunye nemicimbi yendalo esingqongileyo, iDacromet yeyona nto ilungele ukomelela okuphezulu kunye neemfuno eziphezulu ze-anti-corrosion.
IXESHA LOKUQALA: I-19 ukuya kwi-1923
