Ake sinqamule i-marketing fluff. Lapho othile ebuza ngokuqina kwepuleti elishumekwe elenziwe nge-electro-galvanized, bavame ukubuza ngempela: Ingabe le nto izogqwala kimina eminyakeni emihlanu, noma ngingayikhohlwa? Impendulo emfushane, engakhululekile ithi: kuncike ngokuphelele kulokho oshumeka kukho, futhi okubaluleke kakhulu, ukuthi uxhumani kuyo. Ngibone amapuleti abukeka emsulwa ngemuva kweminyaka eyishumi namanye aqala ukukhombisa amabala amhlophe okugqwala ngaphansi kwamabili. Iphutha elivamile ukuphatha i-zinc enamathela njengesihlangu somlingo, ungayinaki umshado we-electrochemical-noma impi-ungena uma usufakiwe.

Iqiniso Lomhlatshelo Wezinc

I-Electro-galvanizing iyinqubo enzima ngesizathu. Ishibhile uma kuqhathaniswa, ihlinzeka ngenalethi engaguquki, ebushelelezi, futhi inikeza ukuvikelwa kokugqwala okuhloniphekile kwepuleti ngokwalo ezindaweni eziningi. Ibinzana eliyisihluthulelo lingelepuleti ngokwalo. Lapho nje ushisela i-stud noma ubhilidi okuthile ngakho, uke wehlise ukugqoka ngaleso sikhathi. Umbuzo wokuqina ube ususuka kupuleti uye kusistimu yokubopha. Uma usebenzisa i-carbon steel bolt, udale umbhangqwana wakudala we-galvanic. I-zinc izovikela ngokuzidela leyo bhawodi, igqwale ngokushesha ezindaweni zokuxhuma. Ngikhumbula iphrojekthi yokubeka amashalofu lapho sasebenzisa khona amapuleti e-EG ajwayelekile anamahange ensimbi angenalutho. Amapuleti ayelungile, kodwa amakhanda okusetshenzwa kwehange ayeyingxubevange yokugqwala okubomvu phakathi neminyaka emithathu kuleyo ndawo emaphakathi enomswakama. Ukulungiswa kwakungewona ungqimba lwezinc olujiyile epuletini; ibishintshela kuma-hot-dip ama-galvanized noma amahange angenabala ukuze ifane kangcono namandla e-galvanic.

Ukuqina kwe-coating umugqa wakho wokuqala wokuzivikela, kodwa akuyona nje inombolo eshidini elicacisiwe. I-5-micron coating ingase yanele ukukhwezwa kwephaneli yokulawula eyomile, yasendlini. Zama lokho epuletini elibekwe onqenqemeni lukakhonkolo egalaji lokupaka lapho kusetshenziswa khona usawoti wokuqeda uqweqwe lukasawoti, futhi uzobe ubheka ukwehluleka ebusika abambalwa. Umthetho wesithupha? Kuzinhlelo zokusebenza zangaphandle, ezisezingeni eliphansi, ngiyangabaza ukucacisa noma yini engaphansi kwama-microns ayi-12. Noma kunjalo, akukhona nje ngokufana kokuqina. Imiphetho, izindawo ezisikiwe, nezindawo zokushisela yilapho kuqala khona ukwehluleka. Umphakeli omuhle uzoba nenqubo elawulwayo yokuhlanganisa kabusha noma ukuvala lezi zindawo ngemva kokwenziwa, kodwa lokho kuyisinyathelo esengeziwe futhi kubiza abaningi abazama ukweqa.

Bese kuba khona ukulungiswa kwesisekelo sensimbi. Yilapho uhlukanisa khona abahlinzeki abahloniphekile kulabo abanenkinga. Uma insimbi ingahlanzwa kahle futhi ifakwe emanzini ngaphambi kokugeza i-zinc, ukunamathela akubi kahle. Ngike ngabona ukumboza amabhamuza nokuxebuka kumashidi ngesikhathi sokuphatha, ingasaphathwa eyokusensimini. Ukwehluleka ongakwazi ukukubona kusenesikhathi uma wazi ukuthi yini okufanele uyibheke: ukubukeka okunamabalakasha noma ukunamathela okungekuhle emaphethelweni agundiwe. Inkampani efana I-Handan Zitai Fetesser Comment Co, Ltd., esekelwe kuhabhu enkulu yokubopha yase-China e-Yongnian, ngokuvamile inesikali nokulawulwa kwenqubo ukuze kulawuleke lokhu ngokungaguquki, yingakho kubalulekile ukuthola izinto ezisekelweni ezisunguliwe zokukhiqiza. Indawo yabo eduze kwemizila emikhulu yezokuthutha efana ne-Beijing-Guangzhou Railway isho ukuthi bahlelelwe inqwaba, ikhwalithi evamile, hhayi imisebenzi yezandla eyodwa.

I-Embedded Environment iyiNkosi

Awukwazi ukukhuluma ngokuqina kwepuleti ngaphandle kokukhuluma ngokhonkolo. Lokhu ukuguquguquka okukhulu kakhulu. Ukhonkolo ongcoliswe i-alumina ephezulu noma i-chloride yisigwebo sentambo sanoma iyiphi insimbi eshumekiwe, eyenziwe nge-electro-galvanized noma cha. Imvelo ene-alkali kakhonkolo wekhwalithi enhle isiza ngempela ukudlula i-zinc, yakhe ungqimba oluzinzile olubambezela ukugqwala. Kodwa ukhonkolo akuyona into eyodwa. Bengibambe iqhaza kuphrojekthi ye-marine pier lapho i-spec ibiza ukushumekwa kwe-electro-galvanized. Kwakuyinhlekelele elindele ukwenzeka. Ukuchayeka njalo kwe-chloride okuvela kwisifutho sikasawoti kanye nokungena kwendawo ye-splash kweqa umthamo womhlatshelo we-zinc ngokushesha. Bekufanele senze i-oda lokushintsha elimaphakathi nephrojekthi ku-rebar ene-epoxy-coated kanye nezinduku zokubopha ibala, amapuleti ashintshiwe ukuze afakwe i-hot-dip galvanized. Isifundo esibizayo ekuhloleni imvelo.

Ukulimala kokufakwa kungomunye umbulali othule. Izisebenzi ezijikijela amapuleti abe amafomu, ukuhamba phezu kwawo, noma ukuhudulwa amakheji ensimbi phezu kwawo kunganwaya ukunamathela kuze kube yinsimbi engenalutho. Uma sekushumekiwe, lokho kuklwebha kuba i-anode kuseli elincane le-galvanic, okusheshisa ukugqwala kwendawo. Manje ngigcizelela ezinyathelweni ezilula zokuvikela ezifana netheyiphu yesikhashana ezingxenyeni ezinentambo noma ngicacisa ukuthi amapuleti abekwe ngemuva kokusetha umata wokuqala we-rebar. Yengeza mhlawumbe u-5% esikhathini sabasebenzi kodwa ingaphinda kabili impilo yesevisi ephumelelayo.

Kuthiwani ngokuxhunywa kwezinye izinsimbi? Yilapho amashadi ochungechunge lwe-galvanic eba ukufunda ngaphambi kokulala. Ukuxhuma ipuleti elenziwe nge-electro-galvanized (insimbi evalwe nge-zinc) endaweni yokufaka yethusi noma ipayipi lethusi elingaphansi komhlaba kucela inkinga. I-zinc izogqwala ngamandla ukuze ivikele ithusi elihle kakhulu. Ngikubonile lokhu kuma-plumbing utility support. Isixazululo siwukuhlukanisa—ukusebenzisa amabhushi e-dielectric noma amawasha ukuphula indlela kagesi phakathi kwezinsimbi ezingafani. Kuyingxenye encane, eshibhile cishe njalo enganakwa kuma-specs okuqala.

Lapho Okuhle Kwanele Akukho

Kukhona isikhathi nendawo yokushumekwa kwe-electro-galvanized. Ingaphakathi, izindawo ezomile, izisekelo zemishini lapho ukuxhumana kubuye kuhlanganiswe ne-zinc? Kuwukukhetha okuzwakalayo ngokuphelele, okungabizi kakhulu. Izinkinga zivela lapho isetshenziswa njengokucaciswa okuzenzakalelayo ngaphandle kokuthi kungani. Ngibuyekeze inqwaba yemidwebo yesakhiwo lapho konke ukushumeka kuphawulwa ngokuthi i-EG ngenxa nje yokuthi bekusemininingwaneni yephrojekthi yokugcina.

Senze uvivinyo lokuqhathanisa eminyakeni embalwa edlule, sagqiba amasampula amapuleti avela ezinqubweni ezihlukene emgodini wokuhlola onenhlabathi enolaka, ethinteka usawoti. Amasampula enziwe nge-electro-galvanized abonise ukulahleka okukhulu kwe-zinc kanye nokugqwala kwensimbi eyisisekelo emaphethelweni phakathi nezinyanga eziyi-18. Amasampula ediphu ashisayo ayesanda kuqala ukubonisa i-zinc patina. Amasampula ensimbi engagqwali? Ngokubukeka okungashintshiwe. Isilinganiso sezindleko sasicishe sibe ngu-1:1.5:4. Isilinganiso sokuqina besingalingani; kwakufana no-1:3:20 kuleyo ndawo. Icala lebhizinisi lokusebenzisa imali ngaphambili libe sobala kakhulu kulolo hlelo lokusebenza oluthile.

Yilapho ingxoxo ye-supply chain iba ngokoqobo. Ngobuningi, amapuleti ashumekiwe ajwayelekile, umkhiqizi ofana neZitai Fastener (ungathola ububanzi bawo kokuthi https://www.zitaifasteners.com) kunengqondo. Bakhiqiza esikalini esiqinisekisa ukuhambisana kwenqubo yamabanga ajwayelekile kanye nezingubo. Kodwa endaweni ebucayi kakhulu noma ebolayo, kungase kudingeke udlulele ngale kwekhathalogi yabo evamile—ucacisa uqweqwe olushubile, ukwelashwa kwe-chromate passivation ngemva kokufakwa uthayela, noma ngisho nensimbi ehlukile ye-substrate. Umbuzo uwukuthi ingabe ulayini wabo wokukhiqiza uvumelana nezimo ngokwanele kulawo ma-oda wangokwezifiso, noma uma ungcono kunomkhiqizi okhethekile.

Amamodi Okwehluleka nokuthi Yini Ongayibheka

Ukwehluleka ukuqina akuvamile ukuthi ipuleti lihlukane kabili. Ukulahlekelwa umsebenzi. Imodi evame kakhulu ukubanjwa kwentambo. I-zinc igqwala emiculweni yezikhonkwane ezishiselwe, inwebeka futhi ikhiye inadi. Ngichithe amahora osizi endaweni nginama-wrenches namathoshi ngizama ukukhulula amantongomane ekushumekiweyo okwakuneminyaka eyisithupha kuphela ubudala. Ukusebenzisa i-pitch yochungechunge oluqinile noma ukufaka i-zinc ephezulu evimbela ukubamba ngesikhathi sokufakwa kulula, ukunciphisa okushibhile okucishe kungabi ku-speci esijwayelekile.

Okunye ukunciphisa amandla okukhipha. Njengoba ipuleti nezikhonkwane zalo zigqwala, i-cross-section ephumelelayo iyancipha. Lokhu kubalulekile kumahange abaluleke kakhulu kwezokuphepha njengamasistimu okuvikela ukuwa noma i-seismic bracing. Asinazo izindlela ezinhle ezingezona ezonakalisi zokuhlola lokhu uma sekushunyekiwe, yingakho ukucaciswa kokuqala nokubuyekezwa kwemvelo kubaluleke kakhulu. Uma uhlola isakhiwo esikhona, bheka ukugqwala okukhalayo okuvela kukhonkolo ezungeze ukushumeka. Lokho kuwuphawu lwenganekwane lokugqwala okusebenzayo. Ngesikhathi ubona lokho, ukulahlekelwa kwesigaba sekuvele kubalulekile.

Ngezinye izikhathi ukwehluleka kuwubuhle. Ukugqwala okumhlophe (i-zinc oxide) kungcola ezindaweni zikakhonkolo eziqediwe. Akukona ukuyekethisa ngokwesakhiwo kusenesikhathi, kodwa kubukeka kabi ku-facade. Lokhu kuvame ukwenzeka lapho amapuleti egcinwe esimweni esiswakeme ngaphambi kokushumeka, okubangela ibala lokugcina elimanzi. Kuyinkinga yokulawula ikhwalithi kumnikezeli noma indawo yokugcina impahla. Umphakeli omuhle uyomisa kahle futhi apakishe amapuleti ukuvimbela lokhu. Uma uthola amapuleti asevele ekhombisa indawo emhlophe, eyimpuphu eqondile ukusuka kukhreyithi, wenqabe. Leyo ngubo evikelayo isivele idliwe kancane ngaphambi kokuthi yenze nomsebenzi wayo.

Isinqumo: Ukukhetha Okubaliwe

Ngakho-ke, ingabe ipuleti elishumekwe elenziwe nge-electro-galvanized lihlala isikhathi eside? Kungaba njalo, kodwa ukuqina kwayo akuyona impahla engaphakathi. Kuyimpahla yesistimu. Uthenga ingxenye enesendlalelo somhlatshelo. Ubude bayo bempilo buncike ekuhlaseleni kwendawo ezungezile, ikhwalithi yohlelo lokumboza, izinsimbi ezithintayo, nokunakekelwa ngesikhathi sokufakwa. Akuyona isethi futhi ukhohlwe isixazululo ezimweni ezinzima.

Ezindaweni ezingabalulekile, zangaphakathi, noma ezilawulwayo, ukukhetha okuhle kakhulu kwezomnotho. Cacisa ubuncane bokujiya obucacile (ngingamela ama-microns angu-12+ nganoma yini engomi ngamathambo), funa isitifiketi kumkhiqizi, futhi uqinisekise ukuthi zonke izinto zokubopha ezixhunyiwe zinento ehambisanayo. Ezindaweni ezingaphandle, ezimanzi, noma ezichayeke nge-chloride, cishe ungcono kakhulu uma ukhuphuka ijika eliqinile uye endaweni eshisayo yokucwilisa amagalani noma imishini ukuze uthole ukujiya, okuqine kakhulu. Ezinhlelweni ezibucayi kakhulu noma ezigqwalile, izindleko eziphakeme zokuqala zokushumeka kwensimbi engagqwali ukuphela kokukhetha okuhlakaniphile.

Ekugcineni, kufika kulokhu: chaza indawo yesevisi kanye nempilo yesevisi edingekayo kuqala. Bese ubheka emuva ipuleti nokuxhumana kwalo. Ungagcini ngokuzenzakalelayo ku-electro-galvanized ngoba yinto yomugqa wonke umuntu ayaziyo. Lokho kucabanga okuzenzakalelayo yikho okuholela ekuhlulekeni ngaphambi kwesikhathi, ukushayelwa ucingo emuva, nokulungiswa okumba eqolo. Ukuqina kukhona, kodwa kuphela uma ukuklama.
