Iibholiti ezimnyama ezifakwe kwi-zinc: ukusungula izinto ezintsha ezizinzileyo? 

Ubona 'i-zinc emnyama ifakwe' kunye 'nozinzo' kwisivakalisi esifanayo, kwaye ingcinga yakho yokuqala ingaba nokuthandabuza. Kulungile. Kwihlabathi elikhawulezayo, ukucwenga ngokwesiko bekumalunga nokuchasa ukubola kunye nobuhle, rhoqo ngeendleko zokusingqongileyo. Umbuzo wangempela awukho nje malunga nengubo ngokwayo, kodwa yonke i-lifecycle-ukusuka kwi-chemistry yokuhlamba i-zinc ukuya ekupheleni kobomi bebhoti kwisakhiwo. Ukubiza nayiphi na i-fastener edibeneyo 'ezinzileyo' ifuna ukujonga ngaphaya kweglosi yentengiso.

Umtsalane kunye neNyaniso yoMnyama uGqibe

Ingubo yokuguqula i-chromate emnyama phezu kwe-zinc ithandwa ngesizathu. Ibonelela ngesithintelo esifanelekileyo somhlwa-ngokuqhelekileyo malunga neeyure ezingama-96 ukuya kumhlwa omhlophe kuvavanyo lwesitshizi setyuwa, nangona ingumzobo welebhu, inyani ilukhuni-kwaye inciphisa ukubonakaliswa kokukhanya. Kwiindibano zombane zabathengi, izinto zangaphakathi zeemoto, okanye izixhobo ezithile zokwakha, lukhetho olusebenzayo. Kodwa nantsi into yokubamba: inkqubo yobumnyama. Iibhafu ezininzi eziqhelekileyo zechromate zinehexavalent chromium, icarcinogen eyaziwayo kunye neflegi ebomvu yokusingqongileyo. Ukuba umboneleli usasebenzisa loo nkqubo, naliphi na ibango lokuzinza liwa phantsi kwinqanaba lokuqala. Ukutshintshela kwi-trivalent chromium okanye nakwizitywini ezingezizo-chromate (ezifana nezisekwe kwi-silane) kulapho incoko iqala khona.

Ndikhumbula iprojekthi kwiminyaka eyadlulayo apho sasichaza iibholithi ezimnyama ze-zinc kwindawo ebiyelweyo yangaphandle. I-spec yayingacacanga, ibizwe nje ngokuba zinc emnyama nge-ASTM B633. Iibholiti zafika, zabonakala zigqibelele. Kwiinyanga ezintandathu ekuhanjisweni kwintsimi, saqala ukubona umhlwa obomvu ongaphambi kwexesha kwiingcambu zentambo. Ingxaki? Ipleyiti isebenzise i-chromate enexabiso eliphantsi, eshinyeneyo yokwambathisa ngombala, kodwa yayibuthuntu kwaye yaqhekeka phantsi koxinzelelo, iveza i-zinc engaphantsi. Umhlwa wakhawuleza ukusuka apho. Yayingekuko ukungaphumeleli kweplating nganye, kodwa a Ukuveliswa okuzinzileyo ekudibaneni kwesicelo. Ukuqina sisiseko sozinzo; inxalenye engaphumeleliyo kwangethuba yeyona nto ingenakukwazi ukuzinza.

Ngoko ke, ukugqitywa akukona nje umbala. Yinkqubo. Umgangatho wensimbi ye-substrate, ubukhulu be-zinc layer (sithetha nge-5-8μm kumabakala amaninzi orhwebo), uhlobo lwe-passivation, kunye ne-sealant yokugqibela. Inkqubo eyomeleleyo ye-zinc emnyama evela kumenzi ohloniphekileyo, njenge I-Sunnian Zitai Festener Fishaner Comment Com. esebenza ngaphandle kwe-hub enkulu yaseTshayina e-Yongnian, ihlala ibandakanya ukulawulwa, imigca yanamhlanje. Indawo yabo kufutshane neendlela ezinkulu zezothutho ezifana ne-Beijing-Guangzhou Railway ayizonkcukacha nje zezothutho; Ithetha ngamakhonkco okubonelela adibeneyo apho izinto eziluhlaza kunye nemveliso egqityiweyo ihamba ngokufanelekileyo, enokuthi inciphise i-carbon footprint ye-logistics-incinci encinci kodwa iyinyani yepuzzle yokuzinza.

Ingaba iBango eliZinzileyo Liwabambe phi Amanzi?

Makhe sisebenzise. Uzinzo kwiifasteners zokuvelisa ezifana I-winc i-winc itshixiwe ixhomekeke kumanqaku ambalwa abambekayo. Okokuqala, ukusebenza kakuhle kwezibonelelo. Iintambo zokucwenga ezikwinqanaba eliphezulu ngoku zisebenzisa iindlela ezilawulwayo, ezivaliweyo zokucoca ezinqumla kakhulu ukusetyenziswa kwamanzi kunye nokubuyisela i-zinc kumanzi amdaka. Xa ndityelele umzi-mveliso ophumeze oku, umahluko wokucaca kwamanzi amdaka wawuqaqambile xa kuthelekiswa neenkqubo ezindala zokulahla inkunkuma. Okwesibini, into yokuphila ixesha elide. Ibholithi ye-zinc emnyama ecutshungulwe ngokufanelekileyo, ene-lubricant eyomileyo yefilimu okanye itywina lewax, inokugqithisa kakhulu inxalenye yezinc eblue-passivated kwindawo ephakathi. Oku kulibazisa imijikelo yokutshintshwa, ukunciphisa inkunkuma yezinto ngokuhamba kwexesha.

Emva koko kukho into yebholithi yokutshixa ngokwayo-isiqwenga senayiloni okanye intambo egqwethekileyo. Oku kuthintela ukukhulula kwi-vibration. Cinga ngentsingiselo yozinzo apho: ikhonkco elihlala liqinile ligcina imfezeko yesakhiwo, lithintela ukusilela okuyintlekele okukhokelela ekubeni iindibano zonke zichithwe. Licandelo elincinci elenza ukuthembeka kwenkqubo enkulu. Ndikhe ndabona iimeko kwizakhelo ezisezantsi zemoto apho ukutshintshela kwisiqhoboshi sokutshixa esicacisiweyo ngokufanelekileyo kwasusa amabango ewaranti anxulumene nokurhabaxa kunye nokukhulula, nto leyo ethetha ukuba iindawo ezimbalwa zenziwe ngokutsha kwaye zatshintshwa.

Kodwa ayingawo onke amabali empumelelo. Siye sazama ukutyhala i-zinc emnyama ‘eluhlaza’—ikhromati e-trivalent, ucingo lwentsimbi oluhlaziyiweyo—kwikhontrakthi yempahla yabathengi exabisa ixabiso. Ukusebenza kwakwanele, kodwa ixabiso lalimalunga ne-15% ngaphezulu. Umxhasi akazange avume. Sifunda ntoni? Inguqulelo ezinzileyo uhlala ekhubeka kumqobo worhwebo ngaphandle kokuba imimiselo okanye imfuno yomthengi wokugqibela iyayiyalela. Indlela yobugcisa ikhona, kodwa imarike ayisoloko izimisele ukuhlawulela ukongiwa kweendleko zokusingqongileyo.

Ikhonkco Lokubonelela kunye neNyaniso yezinto eziphathekayo

Awukwazi ukuvavanya ukuzinza kwi-bolt egqityiweyo yodwa. Kufuneka ujonge phezulu. Ivela phi intonga yentsimbi? Ngaba isuka kwimill eneziko zombane ze-arc zisebenzisa intsimbi ebalulekileyo ye-scrap? Nguwuphi umxube wamandla welo sila kunye nendawo yokucola? Iinkampani ezidityaniswe kwiziseko zemveliso ezifana neSithili saseYongnian zihlala zidibanisa ukufikelela kwimizobo yocingo, unyango lobushushu, kunye neplating, enokunciphisa uthutho oluphakathi. Umvelisi onje ngeZitai Fasteners, ekule nkqubo yokuphilisana kwezidalwa, ekusenokwenzeka ukuba uvelisa iingcingo ekuhlaleni, ezinciphisa ukukhutshwa kwezothutho xa kuthelekiswa nesixokelelwano sobonelelo esahluliweyo samazwekazi.

I-zinc ngokwayo yenye inqaku. I-Zinc plating yinkqubo ye-electrolytic. Ukuqina kwamandla kuphezulu. Ezinye izityalo ezicinga phambili zenza utyalo-mali kwilanga okanye ukwandisa ukufudumeza itanki ukusika ukusetyenziswa kwegesi yendalo. andikayiboni into yokuthathwa kwabantwana ngoku, kodwa amandla akhona. Okwenyani Ukuveliswa okuzinzileyo inokuba kwezinye izinto zokwaleka xa zizonke-njengezinc-flake iinkqubo ezinikezela ngokuxhathisa okugqwesileyo kokutya kunye nokusetyenziswa kwesinyithi esinzima kakhulu. Kodwa kuninzi lwezicelo apho i-zinc emnyama icacisiwe, imalunga nokuphucula okongeziweyo kwinkqubo ekhoyo.

Kwiwebhusayithi yabo, https //wwww.ziitasteners.com, unokubona uluhlu lwezibophelelo abazinikezelayo. Akunjalo nje ngokuthengisa imveliso; imalunga nokubonelela ngedatha yobunjineli-ubukhulu bokugquma, iziphumo zovavanyo lwesitshizi setyuwa, ukusebenza kwe-torque-tension kwiibholiti zokutshixa. Oko kungafihlwa yinto efunekayo kulo naluphi na uvavanyo olunozinzo olunzima. Umthengi akakwazi ukwenza ukhetho olunolwazi ngaphandle kwaloo datha.

Imeko kwindawo: Indawo ebiyelweyo yaNgaphandle iphinde yatyelelwa

Makhe sibuyele kuloo projekthi yokuvala engaphumelelanga. Ukuhlolwa kwesidumbu kwasikhokelela kumboneleli owahlukileyo kunye nenkcazo ehlaziyiweyo. Safudukela kwibholiti emnyama ye-zinc ene-trivalent chromate passivation kunye ne-topcoat ebhityileyo yendalo. Ukusebenza kwesitshizi setyuwa kuye kwaxhuma kwiiyure ezingama-200 ukuya kutsho kumhlwa obomvu. Ixabiso laliphezulu, kodwa ixabiso lilonke lobunini, kubandakanywa ukutshintshwa kwentsimi okuphetshiweyo kunye nomonakalo wegama, wawuphantsi. Leyo yinxaki ezinzileyo: utyalo-mali lokuqala oluphezulu kubomi obude benkonzo kunye nokunciphisa inkunkuma ebangelwa kukungaphumeleli.

Ngaba yayisisisombululo esigqibeleleyo? Hayi. I-topcoat yezinto eziphilayo inokunxiba ngexesha lokufakela ukuba izixhobo aziqapheli. Kwafuneka siqeqeshe abasebenzi bendibano. Uzinzo lusoloko luzisa izinto ezintsonkothileyo ezintsha kumgangatho wevenkile. Ayisiyonto nje yokutshintsha izinto zomlingo.

Apha kulapho uphawu lokutshixa luba lubaluleke kakhulu. Kwezi zivalo, ukungcangcazela kwaba ngumba. Ukusebenzisa a I-zinc ye-winc itshixiwe ngesiqwenga esifakwe ngaphambili siqinisekise ukuba ijoyinti ihleli, ikhusela ukuthembeka kwetywina kunye ne-elektroniki ngaphakathi. I-synergy phakathi kwengubo ehlala ixesha elide kunye nesixhobo sokutshixa esithembekileyo yinto eyenza imveliso eyomeleleyo, yobomi obude. Omnye ngaphandle komnye ubeka esichengeni inkqubo yonke.

Ke, Ngaba Lutshintsho oluZinzileyo?

Kunokuba njalo, kodwa kunemiqathango. I-bolt emnyama ye-zinc efakwe kwi-lock eveliswe ngeenkqubo ezilawulwayo, eziphantsi kwempembelelo, eyenzelwe ixesha elide, kwaye isetyenziswe kwimeko efanelekileyo imele inyathelo eliya kwi-hardware ezinzileyo. Ayilonguquko, kodwa yindaleko. I-innovation ihlala kwiinkcukacha zokuvelisa-unyango lwenkunkuma, ukubuyiswa kwamandla, ukulawulwa kweekhemikhali-ukuba umsebenzisi wokugqibela akaze abone.

Ishishini, kubandakanywa iziseko eziphambili zemveliso kwiindawo ezifana ne-Handan, zihamba kancinci kweli cala, ziqhutywa ziimfuno zekhonkco lokubonelela ngehlabathi kunye nemimiselo yokusingqongileyo. Iteknoloji ikhona. Owona mceli mngeni mkhulu ngowoqoqosho kunye nemfundo: ukukholisa abathengi ukuba bajonge ngaphaya kwexabiso leyunithi kunye nokukhuthaza ukuqonda okunzulu malunga nento engena kwisibophelelo esithembekileyo nesenziwe ngokuthembekileyo.

Ekugqibeleni, musa ukuthatha ileyibhile ezinzileyo kwixabiso lobuso. Gcoba kumaphepha edatha, buza malunga nohlobo lwechromate, inkqubo yokucoca amanzi, ubomi benkonzo obulindelekileyo. Impendulo yokuba ngaba Ukuveliswa okuzinzileyo ilele kwezo nkcukacha, hayi kumnyama oshwabeneyo ohleli ebhokisini.
