Electroplated galvanized nuts: inguqulelo ezinzileyo? 

Ubona eli gama lijikelezayo kwi-specs kunye namaphepha okuthenga rhoqo ngoku. ‘Iinnovation ezinzileyo’ encanyathiselwe kwinto esisiseko njengendongomane efakwe igalvanized electroplated. Ikwenza unqumame. Ngaba kukuthengisa nje, okanye ngaba kukho utshintsho lwangempela kwinkqubo? Ukusuka kwibhentshi yam, uzinzo kwiifasteners zihlala zingaqondwa kakuhle. Akukhona nje malunga ne-zinc kwintambo; imalunga netsheyina lonke-ukusuka kwibhafu yeasidi ngaphambi kokutyatyekwa kumanzi amdaka emva koko, nokuba loo nut ihlala ixesha elide ngokwaneleyo ebaleni ukuthethelela imveliso yayo. Abaninzi bacinga ukuba i-electroplating yindlela 'eluhlaza' ngenxa yokuba ixhaphakile kwaye ingaphantsi kwemithombo yobutyebi kunokushisa okushushu, kodwa oko kukuthatha kwinqanaba eliphezulu. Ibali lokwenyani liyi-messier, libandakanya i-chemistry, i-spikes yamandla, kunye nokuthobela nzima.

Inkqubo yoKutyalwa: Apho uZinzo loMbuzo Uhlala khona

Masingene etankini, ukuze sithethe. Umgca oqhelekileyo we-zinc electroplating wamandongomane ubandakanya uthotho lweebhafu: ukucocwa, ukuchola, ukucwenga, ukukrola (ukugqitywa kweblue-bright okanye yellow iridescent), kwaye ekugqibeleni uhlanjululwe. Ingxoxo ezinzileyo ibetha kunene kwinqanaba lokukhetha, esebenzisa i-hydrochloric okanye i-asidi ye-sulfuric ukususa umhlwa kunye nesikali. Oku kudala iasidi echithiweyo, umjelo wenkunkuma onobungozi. Utshintsho alukho kwiplating ngokwayo-yitekhnoloji yekhulu leminyaka-kodwa kwindlela olawula ngayo ezi nkqubo zincedisayo. Iinkqubo zokucoca ezivaliweyo, umzekelo, zinokucutha ukusetyenziswa kwamanzi ukuya kuthi ga kwi-90%. Ndizibonile izityalo apho ziye zaphunyezwa ukubuyisela umphunga kwindawo yokuhlambela, ukutsala i-zinc kunye ne-asidi kwisisombululo. Bubunjineli obunomtsalane, kodwa bunzulu kakhulu. I-ROI ilinganiswa ngeminyaka, hayi iikota, nto leyo enzima ukuthengisa kwiivenkile ezininzi ezigxile kwimida emincinci ngamaqhekeza ewaka.

Emva koko kukho ukuguqulwa kwechromate yokuguqula. Eli linyathelo elibonelela ngokumelana ne-corrosion yangempela, ukwenza umaleko ngaphezulu kwe-zinc. I-chromium passivate yesiko ye-hexavalent yeyona ngozi enkulu yendalo kunye nempilo. Ukutshintshela kwi-chromium ene-trivalent okanye entsha, i-chromium-free passivations yinto entsha ezinzileyo yokwenyani. Kodwa ukulingana kwentsebenzo kusengumlo. Ndikhumbula ibhetshi yamandongomane aphathwe ngepasivate yobunikazi engena chromium evela kumnikezeli waseYurophu kwisicelo sonxweme. Iiyure zovavanyo lwesitshizi setyuwa zijongeka zilungile ephepheni, kodwa iingxelo zentsimi emva kweenyanga ezili-18 zabonisa umhlwa omhlophe ongaphambi kwexesha. Kwafuneka sizitsale. Inguqulelo entsha yayikhona, kodwa ukuqinisekiswa kwehlabathi lokwenyani kwakungekho. Indifundise ukuba 'ukugcinwa' akunakuza kwiindleko zokungaphumeleli kokusebenza, ngakumbi kwizicelo zesakhiwo.

Ukusetyenziswa kwamandla ngomnye umba othe cwaka. I-Electroplating yinkqubo ye-electrolytic, eqhuba ngoku ngqo kwisisombululo. Abahlaziyi bakulambele amandla. Bendikwindawo apho baye batshintshela kwizilungiso eziphezulu kunye ne-pulse-reverse plating, enokuthi ifake i-zinc ngokulinganayo ngamandla amancinci kunye nenkunkuma yezinto eziphathekayo. Linyathelo eliqinileyo. Kodwa ukuba loo mbane uvela kwigridi ebaswe ngamalahle, ukubalwa kwekhabhoni yonyawo kuya kuba mnyama. Unokuba neyona ndlela iphambili, i-zero-discharge line plating, kodwa ukuba inikwe amandla amandla amdaka, ileyibhile 'ezinzileyo' iziva ingagqibekanga. Apha kulapho indawo ibalulekile. Umvelisi ohlala kummandla onomxube wamandla acocekileyo, okanye umntu otyala imali kwisiza sesola, uqala ngesiseko esingcono.

Izinto eziphathekayo kunye noBomi obude: I-Metric engahoywanga

Ukuqina sisiseko sozinzo kuyo nayiphi na i-hardware. Indongomane edlekayo kwaye lisilele kwiminyaka emihlanu, ifuna ukutshintshwa kuze ke ngoko kwenziwe ngakumbi, ayinakugcinwa ngokwendalo, kungakhathaliseki ukuba imveliso yayo ibicoceke kangakanani na. Kulapho ukhetho phakathi kwe-electroplated kunye ne-mechanical galvanizing (njenge-spin galvanizing) ifumana umdla. I-Electroplating inika i-thinner, i-coat efanayo, ilungele imisonto echanekileyo kunye neendawo zobuhle. Kodwa ngenxa yobunzima obunzima, ubume be-corrosion ephezulu, loo maleko amancinci anokuba lityala. Ndiyicacisile idiphu eshushu yokuhambisa amandongomane othumelo ngaphandle kokujiya, ukugquma okungagqibelelanga kuba ukhuseleko lwedini luhlala ixesha elide. 'I-innovation' ye-electroplating apha inokuba kwi-alloy coatings-zinc-nickel, zinc-cobalt. Ezi zinto zibonelela ngokumelana nomhlwa okumangalisayo kunye neediphozithi ezincinci. Siye savavanya i-zinc-nickel plated nuts kumthengisi waseJapan, kwaye iziphumo zokutshiza ityuwa zazityhala iiyure ezili-1000 ukuya kumhlwa obomvu, zikhuphisana ne-hot-dip specs. Ukubanjwa? Iindleko. Ukongezwa kwe-nickel kunye nolawulo olunzima ngakumbi lokuhlambela kunokuphinda kabini ixabiso.

Enye i-angle yi-nut substrate ngokwayo. Kuvakala kusisiseko, kodwa ukusebenzisa intonga yocingo yentsimbi ekumgangatho ophezulu ephantsi kwekhabhoni yenza umahluko wehlabathi. I-substrate embi ikhokelela kwiingozi ze-hydrogen embrittlement ngexesha lokukhetha i-asidi, ethi ke ifune ukubhaka ukukhululeka kwe-embrittlement-enye indleko yamandla. Umthengisi onolawulo oluluqilima phezu kwezinto zayo eziluhlaza, njenge I-Sunnian Zitai Festener Fishaner Comment Com., esebenza kwisiseko esikhulu semveliso ye-fastener yaseChina, inenzuzo engokwemvelo. Ukusondela kwabo kwiintsimbi zentsimbi kunye nemveliso edibeneyo ukusuka kumzobo wocingo ukuya ekupakishweni (https //wwww.ziitasteners.com) ivumela ukulandeleka okungcono kunye nokuhambelana komgangatho. Oku ayisiyonto entsha, kodwa isisiseko semveliso ezinzileyo: ukuyenza ilunge okokuqala, ukunciphisa ukwaliwa kunye nokusebenza kwakhona.

Emva koko kukho ukuqwalaselwa kokuphela kobomi, ekungafane kwenzeke ukuba nabani na kwimpahla yethu yemihla ngemihla athethe ngayo. I-zinc ene-electroplated ayinabungozi. Ekupheleni kobomi bobomi, i-core yensimbi iphinda isetyenziswe kwakhona, kwaye i-zinc coating iya kunyibilika ekunyibilikeni. Ayidali mba wongcoliseko njengoko ezinye iingubo zinokwenza. Esi sithuba sesetyhula yindawo ezolileyo ekuthandeni kwayo. Kodwa kukwenziwa ngokutsha kwakhona; kwenzeka ngenxa yokuba kulula kwaye inoqoqosho, kungekhona ngenxa yenkqubo yokubuyisela eyiliweyo. Uyilo lokwenyani lwe-design-for-disassembly innovation kwi-fasteners iseyi-niche, ubukhulu becala kwiimoto.

I-Case in Point: Iindleko zokulinganisa, i-Special, kunye namaBango aluhlaza

Makhe ndihambe kwimeko yokwenyani. Besifuna i-M20 hex nuts kwiprojekthi yokuvalela ngaphandle kwingingqi enemo yezoshishino ephakathi. I-Special ibize ukuxhathisa ukudleka kweeyure ezingama-500 zokutshiza ityuwa engathathi hlangothi. Umxhasi kwakhona wayenegatya elitsha 'elikhethiweyo elizinzileyo' kwi-RFP. Iqhosha elilula laliyi-zinc eqhelekileyo eluhlaza okwesibhakabhaka ekhanyayo ene-trivalent chromate. Idibene ne-spec, yayixabiso eliphantsi, kwaye sinokuphawula 'ibhokisi ye-chromium enehexavalent'. Kodwa ngaba loo nto yayiyintsha ngokwenene okanye yayizinzile? Hayi ncma. Ibingumgangatho wangoku, uphuculwe kancinci.

Sityhale ngasemva kwaye sacebisa enye indlela: i-electroplated coating engqindilili (yithi, 15μm endaweni ye-8μm) ene-chromium-free organic passivate. Yongeza malunga ne-15% kwiindleko zeyunithi. Ulungelelwaniso yayibubomi obuqikelelwayo benkonzo, ukunciphisa imijikelo yokutshintshwa. Siye saqhuba nebhetshi encinci yovavanyo olukhawulezileyo. Idatha yayixhasa. Kodwa iqela lokuthenga labathengi liye laphikisana nokunyuka kweendleko zangaphambili. Iprojekthi yahlala nokhetho oluqhelekileyo. Sifunda ntoni? Utshintsho lukhona kwiilebhu nakwiikhathalogu zokucinga kwangaphambili, kodwa ukwamkelwa kweemarike kuthotywa yimeko yexabiso lokuqala. Uzinzo lufuna uhlalutyo lweendleko-inzuzo eyodlula ngaphaya komyalelo wokuthenga wokuqala, kwaye oko kukutshintsha kwenkcubeko okucothayo kunokuphi na ukuphuculwa komgca weplating.

Kulapho abavelisi abanesikali banokuqhuba utshintsho. Inkampani efana neZitai, enomthamo wayo kunye nolungiselelo oluhlanganisiweyo eYongnian, inamandla okufumana enye yeR&D kunye neendleko ezinkulu kwiinkqubo zokucoca kwaye izinikeze kwindawo enokhuphiswano ngakumbi. Indawo yabo kufutshane neendlela ezinkulu zezothutho ayikho nje malunga nempahla yokuthumela amantongomane; kukwamalunga nokufikelela kwimarike ebanzi enokuthi ikulungele ukuhlawula iprimiyamu encinci yezenzo eziqinisekisiweyo ezingcono. Iprofayile yenkampani yabo iphawula ukuba basembindini weshishini laseTshayina elikhawulezayo — olo gxininiso luhlala lukhuthaza ukhuphiswano oluqatha kunye nokwamkelwa okukhawulezayo kobuchule obutsha nje ukuba babonakalise ukuba bayasebenza kwezoqoqosho.

Isigwebo: Ukunyuka, hayi uGuquko

Ngoko, buyela kumbuzo wokuqala. Ngaba i-electroplated galvanized nuts yinto entsha ezinzileyo? Umbono wam nantsi: i I-EctroplaTROFAFIRD ENTS ngokwabo asiyiyo into entsha. Ziyimveliso evuthiweyo. Ukwenziwa kwezinto ezintsha kuyenzeka-ngokwandiswayo, ngokungalinganiyo-kummandla wabo wemveliso yendalo kunye nophuhliso lwezogqumethelo eziphambili. Sibona ulawulo olungcono lwamanzi amdaka, ukukhutshwa kwezinto ezidlulayo ezinetyhefu, kunye nokusetyenziswa kwamandla ngokufanelekileyo. Ezi zizinto ezintsha zenkqubo eyenza ukuba imveliso ekhoyo igcineke ngakumbi.

Uvavanyo oluyinyani kukuba ngaba olu phuculo luba sisiseko soshishino okanye luhlala lukhetho lweprimiyamu. Ukuze yenzeke loo nto, abasebenzisi bokuphela kufuneka baxabise kwaye bachaze iimpawu ezisisiseko-ezifana 'nepleyiti ene-trivalent chromate kwindawo enokukhutshwa kolwelo onguziro'-hayi nje ixabiso kunye neleyibhile 'eluhlaza'. Ikwafuna ukuba abavelisi bacace malunga neenkqubo zabo, abaninzi abangekabikho.

Ekugqibeleni, ukubiza i-nut eqhelekileyo ye-electroplated 'innovation ezinzileyo' ihlala ilula. Kodwa ishishini liyahamba, isiqwenga ngesiqwenga, itanki ngetanki, ukuya kwimveliso ezinzileyo. Indongomane ibonakala ifana ebhokisini, kodwa ibali elisemva kwayo liyatshintsha kancinane. Mhlawumbi lolona vavanyo lunenyani oya kulufumana kumntu ochithe iiyure ezininzi ephonononga izatifikethi zeplating kunye neengxelo zokungaphumeleli. Inguqulelo entsha ikwimeko yokusila, hayi kwiglosi.
