Amapuleti e-Corrosion Resistant Yoke ayizixhumi eziyisisekelo ekudluliselweni nasekusabalaliseni amandla, ezokuthutha ngololiwe, amandla amasha omoya, ingqalasizinda yasogwini, kanye nezimboni zamakhemikhali asindayo. Ngokuyinhloko zisetshenziselwa ukuxhumeka kwentambo yesivikelo, ukudluliswa kwe-conductor tension, kanye nokulungiswa kwenodi yesakhiwo sensimbi. Lawa mapuleti achayeka ezindaweni ezigqwalile ezihlukene, okuhlanganisa umoya wangaphandle, isifutho sikasawoti esisogwini, ama-acid ezimboni kanye nama-alkali, usawoti wenhlabathi, nezimo ezinomswakama nezishisayo. Ukumelana nokugqwala kwazo kunquma ngokuqondile impilo yesevisi yomkhiqizo, ukuphepha kokusebenza, kanye nezindleko zokunakekelwa kwephrojekthi zizonke.
I-substrate iyisisekelo sokuvikela ukugqwala Kwe-Corrosion Resistant Yoke Plate. -Ukugqwala kwekhwalithi ephezulu{2}}Ama-substrate amelana nokugqwala anokumelana nokugqwala okuhle kakhulu, ehlisa ngokuphawulekayo umthwalo wokwelashwa okulandelayo kanye nokuvikela ukugqwala okukabili ngokusebenzisa "i-substrate + surface layer." Ngesikhathi sokukhiqiza, okubalulekile kwe-substrate efanele kufanele kukhethwe ngokunembile ngokusekelwe endaweni yokusebenza yomkhiqizo,{5}}umthamo wokuthwala, nesabelomali sezindleko. Lokhu kusungula umugqa wokuqala oqinile wokuzivikela ekugqwaleni kusukela esigabeni sokungena sezinto ezingavuthiwe, okuyindlela eyisisekelo nehlala isikhathi eside{7}}yokuvikela ukugqwala.
Insimbi yesakhiwo sekhabhoni njengamanje iyisisekelo esisetshenziswa kakhulu ukukhiqiza amapuleti ejoka ajwayelekile angagqwali. Inikeza izindleko ezilawulekayo, izakhiwo ezinhle kakhulu zemishini, nokucubungula kalula. Ngokuthuthukisa izinga lezinto ezibonakalayo kanye nokwakheka kwangaphakathi, ukumelana nokugqwala kwesisekelo kungathuthukiswa, kuyenze ifanelekele izindawo ezivamile zangaphandle{2}}zezimboni ezingagqwali nezwe. Kusetshenziswa insimbi yesimo sezulu ye-Q355NHD ne-Q355NH, enamanani omkhondo wethusi, i-chromium, i-nickel, i-phosphorus, nezinye izakhi ze-alloying ezingeziwe, ifilimu elivikelayo eliminyene neliqhubekayo lingakhiwa phezu kwesisekelo sezinto. Lokhu kuvimbela ngokuphumelelayo ukungena kwemidiya ebolayo efana nomoya-mpilo, umswakama, ne-sulphur dioxide emoyeni, okuholela ekumelaneni nokugqwala komkhathi 2-okuphindwe izikhathi ezingu-3 kunensimbi evamile ye-Q235. Lokhu kuyenza ifanelekele ukukhiqizwa kwamapuleti ejoka ezindaweni ezimaphakathi nezwe kanye nezindawo zezimboni ezingcoliswe kancane. Izitifiketi zezinto ezibonakalayo kufanele zihlolwe lapho izinto zokusetshenziswa zingena efekthri, futhi okuqukethwe kwezakhi zengxubevange kufanele kuhlolwe nge-spectrometer ukuze kuqinisekiswe ukuthi izakhi ezimelana nokugqwala njengethusi, i-chromium, ne-phosphorus ziyahlangabezana namazinga. Kwenqatshelwe ngokuphelele ukusebenzisa insimbi engaphansi encibilikisiwe ensimbi egaywe kabusha ukuze kugwenywe ukungcola okudlulele kwangaphakathi kanye nezakhiwo ze-intergranular ezixekethile, ezisheshisa ukugqwala. Ukusika kwe-Plasma noma ukusika nge-laser kusetshenziselwa ukusika okungenalutho esikhundleni sokusika ilangabi lendabuko ukuze kuncishiswe ubukhulu besikali se-oxide endaweni esikiwe futhi kuncishiswe ubunzima bokususwa kokugqwala okulandelayo.
Amapuleti ejoka amelana nokugqwala adala ingcindezi enkulu yangaphakathi ngesikhathi sokuphonsa, ukubumba, ukushisela, kanye nezinqubo zomshini zokungenalutho. Lokhu kucindezeleka kwangaphakathi kungaholela ekushintshashintsheni komkhiqizo futhi, ezindaweni ezonakalisayo, ukucindezeleka kokubola{1}}ingozi yokugqwala enganakwa kalula ekukhiqizeni. Kusetshenziswa i-hot forging, okulawula izinga lokushisa eliphakathi kuka-850-}1100℃ukuze kuqinisekiswe isisekelo esiminyene esingenasici esifana ne-porosity, ukushwabana kwezimbotshana, nokuqhekeka. Ukupholisa kancane ngemva kokufoja kugwema ukupholisa ngokushesha kanye nokukhiqizwa kwengcindezi yangaphakathi. I-microstructure eminyene ivimba ngempumelelo ukungena kwemidiya ebolayo, inciphisa izindlela zokugqwala ezingeni elingenalutho. Ukufakwa kwesihlabathi okunembayo kusetshenziswa ngesikhathi sokusakazwa kwensimbi eyi-ductile, ukulawula izinga lokushisa elithelayo kanye nezinga lokupholisa ukuze kuncishiswe i-porosity yokuphonsa, izimbobo zesihlabathi, nokufakwa kwe-slag. Ukudubula kwenziwa ngemva kokuphonswa ukuze kukhishwe isikali se-oxide esingaphezulu nesihlabathi esinamathelayo, ukubeka isisekelo esiqinile sokwelashwa okulandelayo kokuqeda ukugqwala.
Ukumayinisa kuyisinyathelo esibalulekile ekwakhiweni kwamapuleti ejoka Amelana nokuCorrosion. Ubulukhuni, ubushelelezi, ama-burrs, kanye nokuklwebheka kwendawo esebenza ngomshini kuthinta ngokuqondile ukunamathela nobuqotho bongqimba olulandela{1}}lokugqwala. Ingaphezulu elimahhadlahhadla lingaholela ekujimeni okungalingani kanye nokuxebuka kwendawo kwesendlalelo esimelene{3}nokugqwala, kuyilapho imidiya ebolayo inganqwabelana kalula ezikhaleni nakuma-burrs, okubangele ukugqwala nokugqwala kwemifantu. Ngakho-ke, umnyombo wokuvimbela ukugqwala enqubweni yokwenza imishini ukulawula ngokuqinile ikhwalithi yendawo bese udala isisekelo sokusebenza esiyisicaba, esibushelelezi, nesinesici{5}samahhala. Ngemva komshini, ukugaywa kwe-pneumatic, ukuhlanzwa nge-ultrasonic, kanye{7}}nokugeza amanzi anomfutho ophezulu kusetshenziselwa ukuhlanza ngokuphelele indawo yokusebenza yamafayili ensimbi, uwoyela, uketshezi lokusika, nama-burrs. Amaphethelo namakhona ayindingilizi futhi ane-chamfer ukugwema imiphetho ecijile engabangela ukunqwabelana okungalingani{9}kwesendlalelo sokugqwala nokuphuma kalula ngenxa yemithelela. Uketshezi olusele lokusika endaweni yokusebenza aluvunyelwe ngokuphelele, njengoba izingxenye zamakhemikhali oketshezini lokusika zingagqwala i-substrate; Ngakho-ke, ukwelashwa kwe-degreasing kwenziwa ngokushesha ngemva komshini.
Ukwelashwa kwendawo kuyindlela ebaluleke kakhulu futhi eqondile emelene-nokugqwala ekukhiqizweni kwama-Corrosion Resistant Yoke Plates. Ngokuvala indawo engaphansi ngesendlalelo esiminyene, esinamathelayo kakhulu, kanye nokugqwala{2}}okungavikeleki, sihlukanisa ngokuphelele i-substrate kusuka kumidiya ebolayo. Izinqubo ezihlukene zokwelashwa kwendawo zisetshenziswa ngesikhathi sokukhiqiza, kuye ngokusetshenziswa komkhiqizo, izidingo zezindleko, nempilo yokuvikela ukugqwala. Lezi zinqubo zihlukaniswa ngezinhlobo ezintathu eziyinhloko: i-anti{5}}corrosion evamile, i-reinforced anti-corrosion, kanye ne-anti{7}}corrosion ekhethekile. Inqubo ngayinye inezincazelo eziqinile zokusebenza kokukhiqiza.
Okushisayo-i-dip galvanizing anti{1}}i-corrosion: Lena okwamanje inqubo evame ukusetshenziswa kakhulu evimbela ukugqwala kwendawo ukuze kukhiqizwe amapuleti ejoka angagqwali ngaphakathi nangaphandle. Ifanele i-carbon steel kanye ne-low-alloy steel substrates, enikeza{6}}ukusebenza okuhle kokubola, izindleko ezimaphakathi, nempilo ende yesevisi. Isetshenziswa kakhulu ezindaweni ezimaphakathi nezwe nezinobukhazikhazi obuncane.
Okushisayo-i-dip galvanizing + sealing coating anti{2}}corrosion: Iqondise ezindaweni ezigqwalile ezifana nezindawo ezisogwini, eduze{3}}nezindawo ezisogwini, ukungcoliswa kwezimboni okumaphakathi, nezimo eziswakeme nezinemvula, le ndlela yengeza ukuvala ungqimba olushisayo{4}lwesendlalelo se-dip, i-dip, i-complete ye-dip ungqimba lokuvalwa kwe-organic." Lokhu kwandisa kakhulu ubude besikhathi sokuvikela ukugqwala futhi kuyisixazululo esivame ukusetshenziswa esiqinisayo sokulwa{7}}sokugqwala kwamapuleti ejoka okuthekelisa.
I-Zinc-i-aluminium coating yokuvikela ukugqwala: Ifanele amapuleti ejoka enziwe ngensimbi{1}}eqinile kanye nezakhiwo ezishiselwe. Igwema ukuqhekeka kwe-hydrogen embrittlement okubangelwa ukucwiliswa, futhi ukumelana kwayo nokugqwala kukudlula kude lokho okuvamile okushisayo-ku-dip galvanizing. Ihlangabezana nezindinganiso zemvelo ze-EU futhi ifanele ukuthunyelwa eYurophu, eMelika, eJapane, eNingizimu Korea, nakwezinye izifunda ezinezidingo eziqinile zemvelo.
Insimbi engagqwali pickling kanye nokuvikela ukugqwala passivation: Okwamapuleti ejoka angagqwali enziwe nge-304, 316, ne-2205 stainless steel, pickling kanye ne-passivation yinqubo yokuvikela ukugqwala komhlaba. Akukho enamathela eyengeziwe edingekayo; ukuvikela ukugqwala kufinyelelwa ngokubuyisela nokuqinisa ifilimu yensimbi engagqwali ye-passivation film. Lesi yisisombululo{6}}esihlala njalo, nesilungisayo{7}}samahhala sokuvikela ukugqwala.
