Ukuqina kwe-shaft yephinikhodi ye-zinc emnyama? 

Ake sinqamule i-marketing fluff. Uma othile ebuza ngokuqina kwephinikhodi emnyama ye-zinc-plated pin shaft, ngokuvamile ulindele ukudumala noma unethemba lesimangaliso. Akuwona u-yebo noma cha olula. Impendulo yangempela ihlala endaweni ebhekene nayo, ikhwalithi yensimbi eyisisekelo, futhi ngokungagwegwesi, ukuthi inqubo yokucwenga yayilawulwa kahle kangakanani. Ngizibonile lezi zikhonkwane zingaphumeleli ezinyangeni futhi zihlala iminyaka, futhi umehluko uvame ukuvela emininingwaneni eminingi yamashidi ayizibayo.

Ukungaqondi Okubalulekile: I-Black Zinc njenge-Finish

Iningi labantu lizwa i-zinc plating futhi licabanga ukuvikela ukugqwala. Abanephutha, kodwa ingxenye emnyama ishintsha umdlalo. Ukufakwa kwe-zinc okujwayelekile okucacile noma okuluhlaza okwesibhakabhaka kunikeza isivikelo somhlatshelo. Ukuqedwa okumnyama kuvame ukuhlanganisa i-chromate yokuguqula esetshenziswa phezu kwe-zinc. Lolu ngqimba olumnyama lwechromate lunikeza umbala kanye nokumelana nokugqwala okwengeziwe, ake sithi, i-chromate ephuzi, kodwa ngokuyisisekelo ijazi eliphezulu. Ukuqina kwayo kuyisihlangu, akusona isithiyo esizilaphayo. Lapho lolo ungqimba olumnyama oluncane seluklwetshiwe noma lugugile, usuke wehlela ku-zinc ngaphansi, bese uya ensimbi. Ngike ngaba namakhasimende akhononda ngamabala okugqwala ezikhonkwane ezintsha ze-zinc ezimnyama ngemva kokuhlanganiswa ngoba ungqimba lwe-chromate lonakaliswe ngokuphatha ngezandla ezingenalutho noma amathuluzi ngaphambi kokufakwa.

I-substrate ibaluleke kakhulu. Iphinikhodi elenziwe ngensimbi enekhabhoni ephansi liqhathaniswa nelilodwa elisuka ebangeni eliphakeme elifana no-1045 noma elingenabala lizoba nemiphumela ehluke kakhulu uma kuqala ukugqwala. I-zinc plating iyisikhumba nje. Uma ingqikithi ibuthakathaka noma ijwayele ukugqwala kwangaphakathi, ukwehluleka kwe-plating kumane kuyisiqalo senkinga. Awukwazi ukugxila phezu kwe-shaft yekhwalithi embi futhi ulindele ukuphila isikhathi eside.

Ukulawula inqubo yikho konke. Ngikhumbula ngithola izikhonkwane zedowel ezimnyama ze-M6 kumnikezeli wasendaweni ukuze ngizihlanganise ezindlini ezingabalulekile. Babebukeka kahle. Kodwa phakathi nezinyanga eziyisithupha endaweni yokugcina impahla enomswakama kancane, ukugqwala okumhlophe (i-zinc oxide) kwaqala ukuqhakaza ngale ndlela emnyama. Inkinga? Ukuhlanzeka okunganele noma ukuwasha ngaphambi kokucwenga, okushiya ukungcola okusheshisa ukugqwala kwefilimu engaphansi. Isiphetho esimnyama sifihle ukungalungiseki kahle kwaze kwaba sekwephuzile.

Ukusebenza Komhlaba Wangempela: Konke Kumayelana Nemvelo

Ezindaweni zasendlini, ezilawulwayo—cabanga ifenisha yasehhovisi, imihlangano yemishini yangaphakathi, izinhlelo zokugcina ezomile—isiphetho se-zinc esimnyama esifakwe kahle ngokuvamile sihlala isikhathi eside. Imelana nokungcoliswa kwezigxivizo zeminwe futhi inikeza ukubukeka okuhloniphekile, okufanayo. Ukumelana nokugqwala lapha kumayelana nokuvimbela ukonakala kunokulwa nezinto ezinolaka. Kulezi zimo, ukuqina kuphezulu.

Ihambise ngaphandle noma endaweni eswakeme, bese indaba iyashintsha. Ngisho nomswakama ophansi onemijikelezo yezinga lokushisa kungaba yinkinga. Ngaba nengxenye kuphrojekthi yabakaki bezimpawu zangaphandle. Sisebenzise izikhonkwane ezimnyama ezifakwe u-zinc kuma-pivots. Ayebukeka emuhle ekuqaleni, ehambisana nobuhle, kodwa edolobheni eliseduze nogu, ukugqwala okubomvu kwaqala ukuvela ezindaweni zokuxhumana phakathi nezinyanga eziyi-18. Inhlanganisela yomswakama, isifutho sikasawoti ngezikhathi ezithile, kanye nokungqubuzana kwakugqokwa ngezingqimba zechromate ne-zinc. Sifunde ukuthi kunoma yiluphi uhlelo lokusebenza oluguqukayo noma ukusetshenziswa kwangaphandle, i-zinc emnyama iyodwa iwukuyekethisa ukuqina.

Ukuba khona kwezinye izinto ezibalulekile. Ezingxenyeni ezine-aluminium noma izinsimbi ezingafani, ukugqwala kwegalvanic kungadla i-zinc plating ngokushesha. Ngikhumbula ukwehluleka endaweni ebiyelwe kagesi lapho kwasetshenziswa khona iphinikhodi ye-zinc emnyama ukuze kuvikeleke ibha yebhasi yethusi. Umbhangqwana we-galvanic washeshisa ukugqwala, okuholela ekubanjweni kanye nephupho elibi ngesikhathi sokulungiswa. I-coating emnyama yenza ukuhlola kokuqala kubukeke kuhlanzekile, kwavala ukusabela okuqhubekayo ngaphansi kuze kube yilapho iphinikhodi selishiselwe endaweni.

Ukuqhathanisa nezinye iziqephu

Kungani ungavele usebenzise insimbi engagqwali? Izindleko kanye ne-galling, ngokuvamile. Kodwa ukuze kuhlale isikhathi eside ezimeni ezinzima, izikhonkwane ezingenabala noma zediphu ezishisayo zikuligi ehlukile. I-zinc emnyama iyinketho yobuhle nokuvikela okulingene. Kwesinye isikhathi siyacacisa I-zinc-plated emnyama izikhonkwane ezivela kumkhiqizi njenge I-Handan Zitai Fetesser Comment Co, Ltd. emishini yasendlini lapho ukubukeka kwe-oxide emnyama kuyadingeka ukuze kubonakale ukukhanya okuphansi ngokumelene namafreyimu amnyama, kodwa siqinisekisa ukuthi indawo ezungezile ivaliwe futhi igcotshiwe. Indawo yabo e-Yongnian, ihabhu lokukhiqiza eliyisigxivizo, kusho ukuthi babone zonke izinhlelo zokusebenza nemodi yokwehluleka, evamise ukuhumushela kulwazi lwenqubo olusebenzayo.

Amaphuzu Okwehluleka: Kuphi Futhi Kungani Aguga

I-Friction isitha esikhulu kunazo zonke. Noma iyiphi iphinikhodi esebenza njengehinge, i-pivot, noma isixhumanisi izobona ukuguga. Izingqimba ze-chromate emnyama nezinc ziwugqinsi wama-microns. Ngaphansi kwemithwalo ye-radial noma eshelelayo, aphuka ngokushesha. Uma usuhambile, uthola ukugqwala kwensimbi phezu kwensimbi noma ukugqwala okusheshisiwe endaweni egugile. Ngiqhaqhe izindlela lapho isikhungo sephinikhodi bekuyinsimbi ekhanyayo, ephucuziwe, kuyilapho iziphetho zisenoqweqwe olumnyama olungaguquki. Ukuqina kwakungekona okokusebenza, kodwa okokusebenza.

Iziphetho ezinezintambo (uma zikhona) zingenye indawo ebuthaka. Ukucwenga emicu kungathinta ubudlelwano be-torque-tension futhi kugundwe kalula ngesikhathi sokufakwa. Imicu yebhawodi yehlombe emnyama enezinki ivamise ukugqwala kuqala ngoba ukucwenga kuyalimala uma kuklinywa endaweni. Kuyimininingwane evame ukunganakwa ngesikhathi sokucaciswa.

I-hydrogen embrittlement ingumbulali othule, ikakhulukazi wezinsimbi ezinamandla kakhulu. Isinyathelo sokuhlanza i-asidi ngaphambi kokuba i-zinc plating yethule i-hydrogen ensimbi, okuholela ekulibazisekeni, nokuphuka okuphukayo ngaphansi komthwalo. Lokhu akuyona inkinga yokuguga kodwa ukwehluleka kokuqina okuyinhlekelele. Abakhiqizi abahloniphekile, njengaleyo e- https://www.zitaifasteners.com, izoba nenqubo yokubhaka ukuze ikhulule le hydrogen. Kodwa akubona bonke abakwenzayo, ikakhulukazi ngamaqoqo ashibhile. Kungumbuzo okufanele uzibuze wona.

Ukwenza Kuhlale Kunjalo: Ukucaciswa Okusebenzayo Nokuphatha

Ungacacisi i-zinc emnyama ngokuhlala isikhathi eside. Yicacise ngokubukeka ngohlangothi lokumelana nokugqwala, bese uyiklama ukuze uyivikele. Yisebenzise ezinhlelweni ezimile, ezomile, noma ezigcotshiwe. Uma iphinikhodi izozungeza noma ishelele, hlela isihlahla noma uqinisekise ukuthi igcotshwa njalo. Ifilimu kawoyela yengeza ungqimba lokuvikela i-plating entula.

Hlola isiphetho ngemuva kokuthola. I-zinc plating enhle emnyama kufanele ifane, ibambelele, futhi ingabi namabala noma izinsalela eziyimpuphu. Yigcobe ngokuqinile ngendwangu emhlophe eyomile. Uma izinsalela ezimnyama ziphuma, i-chromate coating ayizange ivalwe kahle futhi izonikeza ukuvikeleka okuncane. Nginqabile ukuthunyelwa kwalokhu kuhlolwa okulula.

Cabangela ukwelashwa kwangemva kokucwenga. Ngezinhlelo zokusebenza ezidinga kakhulu, i-wax noma idiphu kawoyela ngemva kokucwecwa ingakhuphula kakhulu ukumelana nokugqwala ngokuvala izimbotshana ezincane kungqimba lwechromate. Isinyathelo esilula, esinezindleko eziphansi esinikezwa abahlinzeki abaningi kodwa asihlali sizenzakalelayo.

Ngokuthengwa kwevolumu kusuka kusisekelo esikhulu sokukhiqiza, ukucaca ku-oda lokuthenga kubalulekile. Esikhundleni se-zinc emnyama nje, cacisa izinga (isb., ASTM B633, Fe/Zn 5) kanye namahora okuhlola isifutho sikasawoti esidingekayo (isb., amahora angama-96 ukuya kokugqwala okumhlophe). Lokhu kuphoqa ingxoxo yekhwalithi. Inkampani efana I-Handan Zitai Fastener, esendaweni eyisizinda sengxenye enkulu kunazo zonke e-China, ihloselwe lezi zicelo ezinembile. Ukuba seduze kwabo emizileni emikhulu yezokuthutha kusho ukuthi bajwayele ukuthutha ezindaweni ezihlukahlukene zezulu, okudinga ngokusobala ukulawulwa kwenqubo okuqinile.

Isinqumo Sokugcina: Isivumelwano Esibaliwe

Ngakho-ke, ingabe iphinikhodi emnyama ye-zinc-plated iqinile? Kungaba, kodwa hhayi jikelele. Ukuqina kwayo kunemibandela futhi ngokuvamile kungaphansi kwethemba elingakaqalwa. Iwukuqedela ohweba ukuvikela ukugqwala okuphezulu kobuhle obuthile, obucwebezelayo obuphansi. kwesokudla, indawo evikelekile, izodlula umshini. Kuhlelo olungalungile, oluveziwe, noma oluguqukayo, kuzoba umbhalo waphansi wokulungisa.

Ukuthatha kochwepheshe wukubona njengengxenye yesistimu. Ukuqina kwephinikhodi akukhona nje ukucwecwa; kumayelana nezindlu, umthwalo, umkhathi, kanye nesimiso sokunakekela. Ngiyekile ukuyiphatha njengesiphetho esilula esimelana nokugqwala futhi ngaqala ukuyiphatha njengesendlalelo sezimonyo esinezinzuzo zokuvikela ezimaphakathi. Lokho kushintsha kwesimo sengqondo kuholela kumiklamo ethembeke kakhudlwana kanye nokushayelwa emuva okumbalwa.

Uma udinga lokho kubukeka okumnyama-matte, kusebenzise. Kepha unjiniyela azungeze ukulinganiselwa kwawo. Kwesinye isikhathi, isixazululo esiqine kakhulu ukucacisa iphinikhodi yensimbi engagqwali futhi ibe ne-black-oxided, noma ukusebenzisa iphinikhodi yensimbi ye-carbon steel enogqinsi oluqinile njengejazi lempushana ezingxenyeni eziveziwe. I shaft emnyama ye-zinc-plated inendawo yayo—indawo eqondile, eqondwayo, nekhethwe ngokucophelela. Ukuqina kwayo kwangempela akunqunywanga efekthri, kodwa ebhodini lakho lokudweba nasendaweni yayo yokugcina yokusebenza.
