Ukuqina kwephinikhodi yephinikhodi kagesi? 

Uma othile ebuza mayelana nokuqina kwephini lephinikhodi elenziwe nge-electro-galvanized, umuzwa wami wokuqala ukucacisa: ingabe sikhuluma ngempilo ye-coating noma ubuqotho bokusebenza kwephinikhodi ngaphansi kwalokho kunamathela? Ezikhathini eziningi, abantu babona i-zinc ecwebezelayo iqeda futhi bacabange ukuthi iyihawu elingangenwa izinhlamvu. Akunjalo. Kuyingqimba yomhlatshelo, futhi ukuthi ihlala isikhathi esingakanani kuncike ngokuphelele ekutheni unikela ngani.

Iqiniso le-Zinc Layer

Ake sicacise. I-electro-galvanized coating evamile ku-carbon steel pin shaft ingase ibe cishe ama-microns angu-5-8. Endaweni elawulwayo, eyomile yasendlini, engahlala iminyaka ngaphandle kwenkinga. Kodwa lapho wethula umswakama, usawoti, noma ukuhuzuka okungaguquki, iwashi liqala ukunyakaza ngokushesha. Ngike ngabona izikhonkwane emishinini yezolimo ezindaweni ezisogwini zikhombisa ukugqwala okumhlophe phakathi nezinyanga, hhayi ngenxa yokuthi ukufakwa kwamakethi bekukubi, kodwa ngenxa yokuthi indawo ezungezile ibinolaka kakhulu kunalokho obekushiwo. Umbuzo wokuqina awusizi ngaphandle komongo wendawo yesevisi.

Umgodi owodwa ojwayelekile uwukudida nokufaka i-hot-dip galvanizing. I-Electro-galvanizing incane, ibushelelezi, futhi inikeza ukumelana nokugqwala okuhle kakhulu kwesisindo sayo nezindleko, kodwa akusona isivikelo esisindayo esihlinzekwa yi-hot-dip. Ngikhumbula iphrojekthi lapho iklayenti lasebenzisa izikhonkwane ezenziwe ngogesi ucezu lwesisetshenziswa sokuqina sangaphandle, silindele impilo yeminyaka eyi-10. Baphoxekile ngesikhathi kuvela ukugqwala okubomvu ngemuva kweminyaka emithathu. Ukwehluleka bekungekho ezintweni zephinikhodi noma kunqubo yokumboza ngeseshini ngayinye, kodwa ekungafanini phakathi kokulindela uhlelo lokusebenza kanye nemikhawulo engokwemvelo yokumboza.

Ukunamathela kwe-zinc layer kubalulekile. I-shaft engasetshenziswanga kahle ngaphambili-igrisi, isikali sokugaya, noma ukugqwala okushiywe kuyo-kuzoholela ekugqokeni okuphuma ngaphansi kwengcindezi encane yemishini. Ngihlale ngigcizelela ukubaluleka kwezigaba zokuhlanza nokuqoqa ngaphambi kokugeza kwe-zinc. Iphinikhodi evela kumphakeli ohlonishwayo njengo I-Handan Zitai Fetesser Comment Co, Ltd. e-Yongnian, inhliziyo yesizinda sokukhiqiza sase-China, ngokuvamile izoba nale nqubo phansi. Indawo abakuyo ibanika ukufinyelela ku-ecosystem yemboni egxilile, okusho ukuthi imigqa yabo yokwelapha ngaphambilini ivamise ukusethelwa umthamo nokulingana, okuvame ukuhumushela ekulungiseleleni okungcono kwe-substrate.

Lapho Iphini Libalulekile

Ukuqina akukhona nje ukujula kwesikhumba. I-substrate steel grade yiyona yonke into. An shaft ye-electro-galvanized pin shaft eyenziwe ngensimbi enekhabhoni ephansi efana ne-Q235 (elingana ne-A36) izogoba noma igunde ngaphansi komthwalo isikhathi eside ngaphambi kokuba i-coating ihluleke. Ngamaphoyinti e-pivot anengcindezi ephezulu, udinga ukubheka izinsimbi zekhabhoni emaphakathi noma i-alloy, njengo-45 noma 40Cr, aphathwe ngokushisa abe lukhuni okulungile. Inqubo yokugaya ngokwayo, ehlanganisa ukuhlanzwa kwe-asidi kanye ne-electrolysis, ngezinye izikhathi ingaholela ekugxilweni kwe-hydrogen ezinsimbi zamandla aphezulu uma ingalawulwa kahle emva kokucwenga ngokwelashwa kokubhaka.

Ngikhumbula ngihlola inqwaba yezikhonkwane zohlelo lwesilinda esisebenza ngehydraulic. Zazifakwe uthayela omuhle, kodwa ngaphansi komthwalo oqinile, zazibonakala ziphuka kancane. Imbangela? Umkhiqizi weqe ukubhaka kwe-dehydrogenation ngemva kokucwenga ukuze wonge isikhathi nezindleko. I-zinc yayiphelele, kodwa umnyombo wawusengozini. Lena i-nuance ebalulekile: inqubo ye-electroplating ingathinta izakhiwo zensimbi eyisisekelo. Kufanele uthole kumenzi oqonda iketango eligcwele, hhayi ithangi lokucwenga kuphela.

Kuzinhlelo zokusebenza ezijwayelekile zezimboni, inhlanganisela yephinikhodi yensimbi engu-45, ecishiwe futhi eshibhile ibe lukhuni be-HRC 28-35, bese kuba i-electro-galvanized, iwumsebenzi omkhulu. Inikeza ibhalansi enhle yamandla, ukumelana nokuguga, nokuvikela ukugqwala kwama-assemblies ahlala emanzi noma ehubha. Ungathola le mininingwane njengeminikelo evamile evela kubakhiqizi abaningi abahlanganisiwe esifundeni sase-Yongnian, lapho izinkampani ezifana ne-Zitai Fastener zisebenza ngalolo lwazi oluma mpo olubalulekile.

Ukwehluleka kanye Nokubhekwa Kwenkundla

Ayikho into efundisa njengokwehluleka. Sake saba nesiqukathi sezikhonkwane siphethe amaphepha aphelele, kodwa lapho sihlanganiswa, izintambo (ezazinamekwe) zazivutha. Inkinga? Ugqinsi lwe-electro-galvanized coating emiculweni abuzange bulawuleke ngokwanele, bushintsha ukulingana futhi bubangele ukuphazamiseka. Kwakungekona ukwehluleka ukuqina ngomqondo wokugqwala, kodwa ukusebenza okubangelwa ukumbozwa. Kwadingeka sishintshele kumhlinzeki ohlinzeka ngokuvala imicu okhethekile noma ukuthepha kabusha kwangemva kokucwenga.

Enye i-classic i-corrosion ye-crevice. Ungaba nephinikhodi ebabazekayo, kodwa uma icindezelwe emgodini oyimpumputhe noma ihlanganiswe nensimbi ehlukile efana ne-aluminium ngaphandle kokuhlukaniswa okufanele, udala ugibe oluphelele lomswakama. I-zinc iyazidela, kodwa kuleso sikhala esivalekile, ayikwazi ukumisa ukuhlasela okusheshayo. Ngikhiphe izikhonkwane ebezibukeka zilungile ku-shank evuliwe kodwa ebegqwalile futhi ashaqwe amamilimitha ambalwa nje endlini. Siyini isifundo? Idizayini yesistimu iyingxenye yezibalo zokuqina kwephinikhodi.

Izindawo ezi-abrading ziyisivivinyo sangempela. Ezinhlelweni zokuxhumanisa ezinokuzungeza njalo, ungqimba lwezinc endaweni egugileyo luzoguga ngokushesha, lushiye insimbi engenalutho obala. Kulezi zimo, ukucacisa ukwelashwa kwendawo eqinile, njengokucwecwa kwe-chrome ezindaweni ezithwalayo, noma ukukhetha iphinikhodi eliqiniswe kakhulu nokwamukela ukuthi izogqwala lapho okugugile khona (okuvame ukwamukeleka uma amandla egcinwa), kuyindlela esebenza kakhulu kunokuncika ekuvutheleni uthayela kukodwa.

Iqhaza Lomhlinzeki kanye Nokuthola Okusebenzayo

Lokhu kungiletha ekutholeni umthombo. Lapho udinga onokwethenjelwa shaft ye-electro-galvanized pin shaft, awugcini nje ngokuthenga umkhiqizo; uthenga isilawuli senqubo yomkhiqizi. Umongo wendawo kanye nezimboni zenkampani ubalulekile. I-Handan Zitai Fetesser Comment Co, Ltd., esitholakala Esifundeni sase-Yongnian nengqalasizinda yaso yesibambiso esiminyene, sizuza kumaketanga atholakala endaweni wezinduku zocingo, amakhemikhali ocwecwe, nezinsizakalo zokwelapha ukushisa. Lokhu ngokuvamile kusho ukulawula izindleko okungcono kanye noshintsho olusheshayo lwezinto ezijwayelekile. Ukuba seduze kwabo emizileni emikhulu yezokuthutha efana neBeijing-Guangzhou Railway kanye ne-G4 Expressway, njengoba kuphawulwe kuwebhusayithi yabo. https://www.zitaifasteners.com, akuyona nje ibhonasi yezokuthutha; iphakamisa ukuthi zifakwe emakethe enevolumu ephezulu, enokuncintisana efuna ukusebenza kahle.

Lapho ngihlola umphakeli, angiceli nje ishidi elicacisiwe. Ngibuza ngokwelashwa kwabo kwangemva kokucwecwa kwe-hydrogen. Ngicela umbiko wokuhlolwa kwesifutho sikasawoti esiqondene ngqo nenqwaba, okuhloswe ngaso okungenani amahora angama-96 ukugqwala okumhlophe ezindaweni ezijwayelekile. Ngingase ngicele ngisho nesampula ukuze ngihlole ukunamathela okulula—ukushaya ibhande ngommese ngigcobe itheyiphu ukuze ngibone ukuthi liyaphakama yini. Lawa amasheke asebenzayo ahlukanisa umdayisi wekhathalogi nozakwethu onolwazi.

Ngezinhlelo zokusebenza ezijwayelekile noma ezibucayi, ukuxhumana okuqondile kubalulekile. Ukuchaza indawo yokusebenza okuyiyonayona—ukulayisha umjikelezo, ukuchayeka kwamakhemikhali okungaba khona, amazinga okushisa—kuvumela imboni yobuchwepheshe efana neZitai ukuthi income ukulungiswa. Mhlawumbe i-zinc ejiyile kancane, ukwelashwa kwe-passivation chromate okuhlukile (okuluhlaza okwesibhakabhaka, okuphuzi, noma okumnyama) amahora engeziwe okumelana nokugqwala, noma ukuguqulwa kwesisekelo. Indima yabo njengochwepheshe bokukhiqiza ukuhumusha izidingo zakho zokuqina zibe yimingcele yenqubo.

Imicabango yokuphetha - Luhlelo

Ngakho-ke, buyela embuzweni wokuqala: Kuyimpendulo enemibandela. I-coating inikeza ukuvikelwa okuhle kakhulu, okungabizi kakhulu kwezinhlelo eziningi zokusebenza, kodwa akusona isisombululo sendawo yonke. Ubude bayo bempilo buwumsebenzi wokujiya kokumboza, ukulungiswa kwe-substrate, ukuqina kwemvelo, nokugqokwa kwemishini.

Iphinikhodi eqinile kakhulu yileyo ecaciswe kahle ngomsebenzi wayo. Kwesinye isikhathi, lokho kusho ukwamukela ukuthi i-electro-galvanizing iyisivikelo sezimonyo noma esilula, futhi ezimweni eziqinile, udinga ukukhuphukela ekudiphini okushisayo, ukucwenga ngomshini, noma ezinye izinto ezifana nensimbi engagqwali. Okubalulekile wukweqa umcabango wokuthi i-galvanized iyisigaba esisodwa, esisebenza kahle kakhulu.

Ekugcineni, kufika ekuhlolweni okuthembekile kanye nokuxhumana okucacile phakathi komklami nomkhiqizi. Ukusebenzisa ubuchwepheshe babakhiqizi abakhethekile kumahabhu afana ne-Yongnian kungavala lelo gebe, kuguqule into elula yempahla ibe ingxenye ethembekile, ehlala isikhathi eside. Ungathola okuningi ngamakhono abo esizeni sabo, zitasteners.com, kodwa khumbula, i-spec yokugcina kufanele kube ingxoxo, hhayi nje ukuchofoza.
