Xa umntu ebuza malunga nokuqina kwe-electro-galvanized pin shaft, ithuku lam lokuqala kukucacisa: ngaba sithetha ngobomi bengubo okanye ingqibelelo yokusebenza kwephini phantsi kwaloo ngubo? Rhoqo, abantu babona i-zinc ecwebezelayo igqibezela kwaye bacinge ukuba likhaka elikhusela iimbumbulu. Ayiyo. Ngumaleko wombingelelo, kwaye ixesha elide lihlala lixhomekeke ngokupheleleyo kwinto oyibingelelayo kuyo.

Inyani yeZinc Layer

Makhe sicacise. I-electro-galvanized coating eqhelekileyo kwi-carbon steel pin shaft ingaba malunga ne-5-8 microns. Kwindawo elawulwayo, eyomileyo yangaphakathi, enokuhlala iminyaka ngaphandle kwengxaki. Kodwa okona uzisa ukufuma, iityuwa, okanye i-abrasion engaguqukiyo, iwotshi iqalisa ukuphawula ngokukhawuleza. Ndikhe ndabona izikhonkwane koomatshini bezolimo kwiindawo eziselunxwemeni zibonisa umhlwa omhlophe kwisithuba seenyanga, kungekhona ngenxa yokuba ukugalelwa kwezitshisi kwakubi, kodwa ngenxa yokuba imo engqongileyo yayinoburhalarhume ngaphezu kokuba kuchaziwe. Umbuzo wokuqina awunamsebenzi ngaphandle komxholo wendawo yenkonzo.

Omnye umngxunya oqhelekileyo kukubhidanisa nokugalela idiphu eshushu. I-Electro-galvanizing incinci, igudileyo, kwaye inika ukuxhathisa okugqwesileyo kubunzima bayo kunye neendleko, kodwa ayisiyiyo isikrweqe esinzima esibonelela ngediphu eshushu. Ndikhumbula iprojekthi apho umxhasi wayesebenzisa izikhonkwane ze-electro-galvanized kwiqhekeza lesixhobo sokuzilolonga ngaphandle, elindele ubomi beminyaka eyi-10. Baphoxekile xa kubonakala umhlwa obomvu emva kweminyaka emithathu. Ukungaphumeleli kwakungekho kwizinto zephini okanye inkqubo yokugquma ngesese nganye, kodwa kukungahambelani phakathi kolindelo lwesicelo kunye nemida yendalo yokwaleka.

Ukubambelela kwe-zinc layer kubalulekile. I-shaft engaphathwa kakuhle ngaphambili-igrisi, isikali sokusila, okanye umhlwa oshiywe kuyo-iya kubangela i-coating ephumayo phantsi koxinzelelo oluncinci lomatshini. Ndihlala ndigxininisa ukubaluleka kokucoca kunye nezigaba zokukhetha ngaphambi kokuhlamba i-zinc. I-pin evela kumthengisi ohloniphekileyo njenge I-Sunnian Zitai Festener Fishaner Comment Com. eYongnian, intliziyo yesiseko semveliso yaseTshayina, iya kuba nale nkqubo phantsi. Indawo yabo ibanika ukufikelela kwi-ecosystem yoshishino olugxininisiweyo, oku kuthetha ukuba imigca yabo yonyango lwangaphambili isoloko imiselwe umthamo kunye nokuhambelana, okuguqulela ngokubanzi ukulungiswa okungcono kwe-substrate.

Apho iPin Ibalulekile

Ukuqina abukho nje ubunzulu bolusu. Ibakala lensimbi ye-substrate yiyo yonke into. An I-encro-ye-pin ye-enctro-tift eyenziwe kwintsimbi ephantsi kwekhabhoni efana ne-Q235 (i-A36 elinganayo) iya kugoba okanye ichebe phantsi komthwalo ixesha elide ngaphambi kokuba i-coating ingaphumeleli. Ngamanqaku epivot yoxinzelelo oluphezulu, kufuneka ujonge i-medium-carbon okanye i-alloy steels, njenge-45 okanye i-40Cr, iphathwa ngobushushu ukuya kubulukhuni obufanelekileyo. Inkqubo yokwenza i-galvanizing ngokwayo, ebandakanya ukucocwa kwe-asidi kunye ne-electrolysis, ngamanye amaxesha inokukhokelela kwi-hydrogen embrittlement kwiintsimbi eziphezulu zamandla ukuba ayilawulwa ngokufanelekileyo i-post-plating kunye nonyango lokubhaka.

Ndikhumbula ndivavanya ibhetshi yezikhonkwane kwisicelo se-hydraulic cylinder. Zazifakwe iigalvans ezintle, kodwa phantsi komthwalo onzima, zabonisa ukuphuka okuncinci. Oyena nobangela? Umenzi weqa ukubhaka kwe-dehydrogenation emva kokutyalwa ukuze wonge ixesha kunye neendleko. I-zinc yayigqibelele, kodwa i-core yayiphazamisekile. Le yi-nuance ebalulekileyo: inkqubo ye-electroplating inokuchaphazela iipropati zesiseko sesinyithi. Kuya kufuneka ufumane kumenzi oqonda ikhonkco elipheleleyo, hayi nje itanki yokucwenga.

Ukusetyenziswa kwezoshishino eziqhelekileyo, udibaniso lwepini yensimbi engama-45, ecinywe kwaye igxininiswe kubunzima be-HRC 28-35, kwaye emva koko i-electro-galvanized, i-workhorse. Inika ibhalansi elungileyo yamandla, ukumelana nokunxiba, kunye nokukhuselwa kokugqwala kweendibano ezingahlali zimanzi okanye zirhabaxa. Unokufumana ezi nkcazo njengezinto ezisemgangathweni ezivela kubavelisi abaninzi abadibeneyo kwisithili saseYongnian, apho iinkampani ezifana neZitai Fastener zisebenza ngolwazi oluthe nkqo.

Iintsilelo kunye nokuqwalaselwa kweNdawo

Akukho nto ifundisa njengokungaphumeleli. Sakha safumana isingxobo sezikhonkwane siphethe amaphepha afanelekileyo, kodwa xa sidityaniswa, imisonto (eyayigqunywe) yayirhabaxa. Ingxaki? I-electro-galvanized coating thickness on the threads ayizange ilawulwe ngokuchanekileyo ngokwaneleyo, ukuguqula ukulungelelanisa kunye nokubangela ukuphazamiseka. Yayingekuko ukungaphumeleli kokuqina kwindlela yokubola, kodwa yinto esebenzayo ebangelwa kukugquma. Kwafuneka sitshintshele kumthengisi obonelela ngokukhetha ukugquma imisonto okanye ukucofa kwakhona emva kokucofa.

Enye i-classic yi-corrosion ye-crevice. Unokuba nephini elimangalisayo, kodwa ukuba licinezelwe kumngxunya oyimfama okanye lidityaniswe ngentsimbi eyahlukileyo njenge-aluminiyam ngaphandle kokwahlukaniswa ngokufanelekileyo, wenza umgibe ogqibeleleyo wokufuma. I-zinc iyazincama, kodwa kuloo ndawo ivaliweyo, ayikwazi ukumisa uhlaselo olukhawulezayo. Ndiye ndakhupha izikhonkwane ezibonakala zilungile kwi-shank evuliweyo kodwa zonakaliswe kakhulu kwaye zabanjwa nje iimilimitha ezimbalwa ngaphakathi kwindlu. Sifunda ntoni? Uyilo lwenkqubo luyinxalenye yenxaki yokuqina kwephini.

Imiphezulu ye-abrading luvavanyo lokwenyani. Kwiinkqubo zokudibanisa kunye nokujikeleza rhoqo, i-zinc layer kwindawo yokunxiba iya kuguga ngokukhawuleza, ishiye intsimbi engenanto. Kule meko, ukucacisa unyango olunzima ngakumbi, njengokufakwa kwe-chrome kwiindawo zokuthwala, okanye ukukhetha i-pin-hardened pin kunye nokwamkela ukuba iya kugqwala kwindawo yokunxiba (ehlala iyamkeleka ukuba amandla agcinwe), yindlela esebenzayo ngakumbi kunokuxhomekeka kwi-galvanizing yodwa.

Indima yoMboneleli kunye nokuFumana okuSebenzayo

Oku kundizisa ekufuneni. Xa ufuna ethembekileyo I-encro-ye-pin ye-enctro-tift, awuthengi nje imveliso; uthenga inkqubo yolawulo lomenzi. Umongo wejografi kunye neshishini lenkampani ubalulekile. I-Sunnian Zitai Festener Fishaner Comment Com., emi kwiSithili saseYongnian kunye neziseko zayo ezishinyeneyo zokuqhoboshela, iingenelo kumakhonkco obonelelo asekuhlaleni entonga yocingo, iikhemikhali zokucola, kunye neenkonzo zokunyanga ubushushu. Oku kudla ngokuthetha ulawulo olungcono lweendleko kunye nokuguqulwa ngokukhawuleza kwezinto eziqhelekileyo. Ukusondela kwabo kwiindlela ezinkulu zothutho ezifana neBeijing-Guangzhou Railway kunye neG4 Expressway, njengoko kuphawuliwe kwiwebhusayithi yabo. https //wwww.ziitasteners.com, ayisiyiyo ibhonasi yolungiselelo; icebisa ukuba zifakwe kwixabiso eliphezulu, imarike yokhuphiswano efuna ukusebenza kakuhle.

Xa ndivavanya umthengisi, andiceli nje iphepha elithile. Ndiyabuza malunga nonyango lwabo lwasemva kokufakwa kwe-hydrogen. Ndicela ingxelo yovavanyo lwesitshizi setyuwa ngokuthe ngqo kwibhetshi, ejonge ubuncinci beeyure ezingama-96 ukuya kumhlwa omhlophe kwindawo eqhelekileyo. Ndisenokude ndicele isampulu zokwenza uvavanyo olulula lokuncamathela—ndikore isambatho ngemela ndize ndiqabe iteyiphu ukuze ndibone ukuba iyanyuswa na. Ezi zitshekhi ezisebenzayo ezahlula umthengisi wekhathalogu kwiqabane elinolwazi.

Kwizicelo zesiko okanye ezibalulekileyo, unxibelelwano oluthe ngqo lungundoqo. Ukuchaza indawo echanekileyo yokusebenza-ukulayishwa kwe-cyclic, ukuvezwa kweekhemikhali ezinokuthi, iqondo lokushisa-ivumela i-factory yobugcisa efana neZitai ukucebisa uhlengahlengiso. Mhlawumbi yi-coating ye-zinc engqindilili kancinci, unyango olwahlukileyo lwe-chromate ye-passivation (eluhlaza okwesibhakabhaka, etyheli, okanye emnyama) kwiiyure ezongezelelweyo zokuxhathisa ukubola, okanye utshintsho kwisiseko sezinto. Indima yabo njengengcali yokuvelisa kukuguqulela iimfuno zakho zokuqina kwiiparamitha zenkqubo.

Iingcamango zokuqukumbela - yiNkqubo

Ke, buyela kumbuzo wokuqala: Yimpendulo enemiqathango. Ukugquma kunika ukhuseleko olugqwesileyo, olungabizi kakhulu kuluhlu olubanzi lwezicelo, kodwa akusiyo isisombululo sendalo yonke. Ubomi bayo bungumsebenzi wobunzima bokugquma, ukulungiswa kwe-substrate, ubunzima bokusingqongileyo, kunye nokunxitywa koomatshini.

Esona phini sibambekayo seso sichazwe ngokuchanekileyo kumsebenzi waso. Ngamanye amaxesha, oko kuthetha ukwamkela ukuba i-electro-galvanizing iyisithambiso okanye isiphelo sokhuseleko olulula, kwaye kwiimeko ezinzima, kufuneka unyuke ukuya ku-hot-dip, i-mechanical plating, okanye ezinye izinto ezifana nensimbi engenasici. Into ephambili kukuhamba ngaphaya kwentelekelelo yokuba igalvanized yinqanaba elinye, elisebenza kakhulu.

Ekugqibeleni, kuhla kuvavanyo olunyanisekileyo kunye nonxibelelwano olucacileyo phakathi komyili kunye nomenzi. Ukusebenzisa ubuchule babavelisi abakhethekileyo kwiihabhu ezifana neYongnian kunokuvala eso sikhewu, siguqule into elula yorhwebo ibe yinto ethembekileyo, ehlala ixesha elide. Ungafumana ngakumbi kubuchule babo kwindawo yabo, I-Zitafasteners.com, kodwa khumbula, i-spec yokugqibela kufuneka ibe yincoko, hayi nje ukucofa.
