Makhe sinqumle i-fluff yokuthengisa. Xa umntu ebuza malunga nokuqina kwe-zinc-plated pin shaft emnyama, bahlala bejonge ukuphoxeka okanye banethemba lommangaliso. Ayingo-ewe elula okanye hayi. Impendulo yokwenyani ihlala kwindawo ejongene nayo, umgangatho wesiseko sesinyithi, kwaye ngokungafihlisiyo, indlela inkqubo yokucwenga yayilawulwa kakuhle. Ndizibonile ezi zikhonkwane zisilela kwiinyanga kwaye zahlala iminyaka, kwaye umahluko uhlala uhla kwiinkcukacha uninzi lwamaphepha aluhoywayo.

Ukungaqondi kakuhle: I-Zinc emnyama njengeSigqibo

Uninzi lwabantu luva i-zinc plating kwaye bacinge ngokukhuselwa komhlwa. Ayilunganga, kodwa inxalenye emnyama itshintsha umdlalo. I-standard ecacileyo okanye eluhlaza okwesibhakabhaka i-zinc plating inikeza ukhuseleko lombingelelo. Ukugqitywa okumnyama ngokuqhelekileyo kukuguqulwa kwechromate yokuguqula ifakwe phezu kwe-zinc. Lo maleko umnyama wechromate ubonelela ngombala kunye nokumelana nomhlwa ngakumbi kunokuba, yithi, ichromate etyheli, kodwa ngokusisiseko yidyasi ephezulu. Ukomelela kwayo kulikhaka, kungekhona umqobo wokuziphilisa. Nje ukuba umaleko omnyama ukrwelwe okanye unxitywe, wehla uye kwi-zinc ngaphantsi, emva koko uye kwintsimbi. Ndiye ndaba nabathengi bakhalaza malunga namabala omhlwa kwizikhonkwane ezitsha ezimnyama ze-zinc emva kokuhlanganisana ngenxa yokuba umaleko wechromate waphazamiseka ngokuphatha ngezandla okanye izixhobo phambi kofakelo.

I-substrate ibaluleke kakhulu. Iphini yentsimbi eyenziwe ngentsimbi enekhabhoni ephantsi xa ithelekiswa nenye ukusuka kwibakala eliphakamileyo elifana ne-1045 okanye nokuba ingenasilaphu iya kuba neziphumo ezahlukileyo ngokugqithisileyo xa umhlwa uqalile. I-zinc plating lusu nje. Ukuba undoqo ubuthathaka okanye uthambekele kukonakala kwangaphakathi, ukungaphumeleli kweplating sisiqalo nje sengxaki. Awukwazi ukubeka phezu kwe-shaft esemgangathweni kwaye ulindele ubomi obude.

Ulawulo lwenkqubo yinto yonke. Ndikhumbula ndikhangela izikhonkwane zedoweli ezimnyama ezizinki eziM6 kumthengisi wasekhaya ukwenzela indibano engabalulekanga yangaphakathi. Babekhangeleka kakuhle. Kodwa kwisithuba nje seenyanga ezintandathu kwindawo yokugcina izinto efumileyo, umhlwa omhlophe (izinc oxide) waqalisa ukudubula kulo mhlaba umnyama. Ingxaki? Ukungacoceki ngokwaneleyo okanye ukuhlanjululwa phambi kokutyalwa, okushiya ungcoliseko olukhawulezisa ukubola kwefilimu engaphantsi. Ukugqiba okumnyama kwakufihla ukulungiswa kakubi kwade kwahlwa.

Ukusebenza kwehlabathi lokwenyani: Yonke imalunga nokusiNgqongileyo

Kwiindawo zangaphakathi, ezilawulwayo-cinga ifenitshala yeofisi, iindibano zangaphakathi zomatshini, iinkqubo zokugcina ezomileyo-ukugqiba ngokufanelekileyo kwe-zinc emnyama ihlala ihlala ngokugqibeleleyo. Ixhathisa ibala leminwe kwaye inika inkangeleko endilisekileyo, efanayo. Ukumelana nomhlwa kumalunga nokuthintela ukonakala kunokulwa nezinto ezinobundlobongela. Kwezi meko, ukuqina kuphezulu.

Yikhuphele ngaphandle okanye kwindawo efumileyo, kwaye ibali liyatshintsha. Nokuba ukufuma okuphakathi kunye nemijikelo yobushushu kunokuba yingxaki. Ndabandakanyeka kwiprojekthi yezibiyeli zemiqondiso yangaphandle. Sasebenzisa izikhonkwane ezimnyama ze-zinc kwiipivots. Babukeka bebahle ekuqaleni, behambelana nobuhle, kodwa kwisixeko esikufuphi nonxweme, umhlwa obomvu waqala ukuvela kwindawo zokunxibelelana phakathi kweenyanga ezili-18. Indibaniselwano yokufuma, isitshizi setyuwa ngamaxesha athile, kunye nokukhuhlana kunxitywa kwichromate kunye ne-zinc layers. Sifunde ukuba kuyo nayiphi na inkqubo eguqukayo okanye ukusetyenziswa kwangaphandle, i-zinc emnyama iyodwa kukuthomalalisa ukuqina.

Ubukho bezinye izinto eziphathekayo bubalulekile. Kwiindibano ezine-aluminiyam okanye isinyithi esingafaniyo, i-galvanic corrosion inokutya i-zinc plating ngokukhawuleza. Ndikhumbula ukusilela kwindawo ebiyelweyo yombane apho kwakusetyenziswa ipini yezinki emnyama ukukhusela ibhasbar yobhedu. Isibini esine-galvanic sanyusa i-corrosion, ekhokelela ekubanjweni kunye ne-nightmare ngexesha lokugcinwa. Ingubo emnyama yenza ukuba uhlolo lokuqala lubukeke lucocekile, lugquma impendulo eqhubekayo ngaphantsi de isikhonkwane sidityaniswe endaweni.

Ukuthelekisa nezinye iziphelo

Kutheni ungasebenzisi nje isinyithi esingenasici? Iindleko kunye nentlungu, rhoqo. Kodwa ngenxa yokuqina kwiimeko ezinzima, izikhonkwane ezingenastainless okanye ezishushu-dip zikwiligi eyahlukileyo. I-zinc emnyama yinto yobuhle kunye nokukhusela okuphakathi. Ngamanye amaxesha siyacacisa I-winc-idweliswe izikhonkwane ezivela kumvelisi ezifana I-Sunnian Zitai Festener Fishaner Comment Com. koomatshini bangaphakathi apho inkangeleko yeoksidi emnyama iyadingeka ukuze kubonakale ukukhanya okuphantsi ngokuchasene nezakhelo ezimnyama, kodwa siyaqinisekisa ukuba okusingqongileyo kutywiniwe kwaye kuthathiwe. Indawo yabo eYongnian, indawo yemveliso ekhawulezayo, ithetha ukuba babone zonke izicelo kunye nemowudi yokusilela, ehlala iguqulela kulwazi lwenkqubo yepragmatic.

Amanqaku Okusilela: Apho kwaye Isizathu Sokuba Ziguge

Ukukhuhlana lolona tshaba lukhulu. Nayiphi na i-pin shaft esebenza njengehenjisi, i-pivot, okanye ikhonkco iya kubona ukunxitywa. I-chromate emnyama kunye ne-zinc layers zi-microns ezinzima. Ngaphantsi kwemithwalo ye-radial okanye i-sliding, i-brade ngokukhawuleza. Nje ukuba uhambile, ufumana ukunxitywa kwentsimbi-kwintsimbi okanye ukubola okukhawulezileyo kumjelo ogugileyo. Ndiye ndaqhawuka iindlela apho umbindi we-pin shaft ubukhazimle, intsimbi ekhazimlisiweyo, ngelixa iziphelo zisenencasa emnyama engaguqukiyo. Ukuqina yayingeyiyo into, kodwa yesicelo.

Iziphelo ezinemisonto (ukuba ziyasebenza) yenye indawo ebuthathaka. Iplating kwimisonto inokuchaphazela ubudlelwane be-torque-tension kwaye ichetywe ngokulula ngexesha lofakelo. Imisonto yebholiti emnyama ye-zinc efakwe emagxeni ihlala igqwala kuqala kuba i-plating yonakaliswa xa ibotshelelwe endaweni. Yinkcukacha ehlala ingahoywa ngexesha lokuchazwa.

I-Hydrogen embrittlement ngumbulali othuleyo, ngakumbi kwiintsimbi ezinamandla kakhulu. Inyathelo lokucoca iasidi phambi kokuba i-zinc plating ingenise i-hydrogen kwintsimbi, ekhokelela ekulibazisekeni, ekuqhekekeni okunokonakala phantsi komthwalo. Lo ayisiyongxaki yokunxiba kodwa yintlekele yokungaphumeleli kokuqina. Abavelisi abathembekileyo, njengale e https //wwww.ziitasteners.com, iya kuba nenkqubo yokubhaka ukukhulula le hydrogen. Kodwa ayingabo bonke abakwenzayo, ngakumbi ngeebhetshi ezishibhile. Ngumbuzo ekufuneka uzibuze wona.

Ukuyenza Igqibelele: Ukucaciswa okuSebenzayo kunye nokuphatha

Musa ukucacisa i-zinc emnyama ngokuhlala yedwa. Yicacise ngenkangeleko enecala lokungatyaleki, kwaye uyilo ukuyikhusela. Yisebenzise kwi-static, eyomileyo, okanye kwi-lubricated applications. Ukuba ipini iya kujikeleza okanye isilayidi, cwangcisa i-bushing okanye uqinisekise ukuba ithambisa rhoqo. Ifilimu yeoli yongeza umaleko wokukhusela i-plating ayinayo.

Jonga ukugqiba xa uyifumene. Ukufakwa kakuhle kwe-zinc emnyama kufuneka kube yinto efanayo, ibambelele, kwaye ngaphandle kwamabala okanye intsalela engumgubo. Gcoba ngokuqinileyo ngelaphu elomileyo elimhlophe. Ukuba intsalela emnyama iphuma, i-chromate coating ayizange itywinwe ngokufanelekileyo kwaye iya kunika ukhuseleko oluncinci. Ndiye ndala ukuthunyelwa kolu vavanyo lulula.

Qwalasela unyango emva kokubekwa. Kwizicelo ezifuna kancinci ngakumbi, iwax okanye idiphu yeoyile emva kokutyalwa inokonyusa kakhulu ukuxhathisa umhlwa ngokutywina iipores ezincinci kumaleko wechromate. Linyathelo elilula, elinexabiso eliphantsi elinikezelwa ngababoneleli abaninzi kodwa alisoloko lisilela.

Ukuthengwa kwevolumu kwisiseko esikhulu sokuvelisa, ukucaca kwi-oda lokuthenga kubalulekile. Esikhundleni se-zinc emnyama nje, cacisa umgangatho (umzekelo, i-ASTM B633, i-Fe / Zn 5) kunye neeyure ezifunekayo zokuvavanya ityuwa yokutshiza (umzekelo, iiyure ezingama-96 ukuya kwi-corrosion emhlophe). Oku kunyanzelisa incoko esemgangathweni. Inkampani efana Handan Zitai Fastener, emi kweyona ndawo inkulu yaseTshayina, ilungiselelwe ezi zicelo zichanekileyo. Ukusondela kwabo kwiindlela eziphambili zothutho kuthetha ukuba baqhele ukuhambisa kwiimozulu ezahlukeneyo, nto leyo efuna ngokungqongqo inkqubo yolawulo oluluqilima.

IsiGqeba sokuGqibela: I-Compromise eBaliweyo

Ke, ngaba i-zinc-plated pin shaft emnyama iyahlala ixesha elide? Inokuba njalo, kodwa hayi jikelele. Ukomelela kwayo kuxhomekeke kwiimeko kwaye ngokufuthi kungaphantsi kwethemba elingaziwayo. Kukugqitywa okurhweba ukhuseleko lokugqwala oluphezulu kwi-aesthetic ethile, i-low-glare aesthetic. Ekunene, indawo ekhuselekileyo, iya kudlula umatshini. Kwisicelo esingalunganga, esiveziweyo, okanye esiguqukayo, iya kuba ngumbhalo osemazantsi wolondolozo.

Ukuthatha kobuchwephesha kukubona njengenxalenye kwinkqubo. Ukuqina kwephini akukho malunga nokucwenga; imalunga nendlu, umthwalo, umoya, kunye neshedyuli yokulondolozwa. Ndiyekile ukuyiphatha njengesiphelo esilula sokumelana nomhlwa kwaye ndaqala ukuyiphatha njengomaleko wokuthambisa onezibonelelo zokhuselo eziphakathi. Olo tshintsho lwengqondo lukhokelela kuyilo oluthembekileyo ngakumbi kunye nee-callback ezimbalwa.

Xa ufuna loo matte-black look, yisebenzise. Kodwa injineli malunga nemida yayo. Ngamanye amaxesha, esona sisombululo sisisigxina kukucacisa ipini yensimbi engenastainless kwaye ibe ne-black-oxided, okanye ukusebenzisa i-carbon steel pin ene-coat engqingqwa, eyomeleleyo njengengubo yomgubo kumacandelo atyhidiweyo. I I-pin emnyama ye-pinc inendawo yayo—indawo ethile, eqondwayo nekhethwe ngenyameko. Ukuqina kwayo okwenyani akumiselwanga kumzi-mveliso, kodwa kwibhodi yakho yomzobo nakwindawo yayo yokugqibela yokusebenza.
