Electro-galvanized embedded plate durability? 

Makhe sinqumle i-fluff yokuthengisa. Xa umntu ebuza malunga nokuqina kwepleyiti ene-electro-galvanized embedded, bahlala bebuza ngokwenene: Ngaba le nto iya kuhlwa kum kwiminyaka emihlanu, okanye ndingayilibala ngayo? Impendulo emfutshane, engathandekiyo yile: ixhomekeke ngokupheleleyo kwinto oyifaka kuyo, kwaye ibaluleke kakhulu, into oyidibanisa nayo. Ndibone iipleyiti ezibonakala zicocekile emva kweminyaka elishumi kwaye ezinye ziqala ukubonisa amabala amhlophe amhlophe ngaphantsi kwesibini. Iphutha eliqhelekileyo liphatha i-zinc coating njengekhaka lomlingo, ukungawuhoyi umtshato we-electrochemical-okanye imfazwe-ingena xa ifakwe.

Inyani yeDini leZinc

I-Electro-galvanizing yinkqubo enzima ngenxa yesizathu. Ixabiso eliphantsi kakhulu, libonelela ngokungaguquguqukiyo, isambatho esigudileyo, kwaye ibonelela ngokhuseleko olufanelekileyo lokutya kwipleyiti ngokwayo kwiindawo ezininzi. Ibinzana eliphambili lelepleyiti ngokwayo. Lo mzuzu udibanisa i-stud okanye uvale into ngayo, uye wabeka esichengeni isambatho ngelo xesha. Umbuzo wokuqina emva koko uyatshintsha ukusuka kwipleyiti ukuya kwisixokelelwano se-fastener. Ukuba usebenzisa i-carbon steel bolt, udale isibini se-galvanic sakudala. I-zinc iya kukhusela ngokuzinikela loo bolt, i-corroding ngokukhawuleza kwiindawo zokuxhuma. Ndikhumbula iprojekthi yokubeka ishelufu apho sasisebenzisa iipleyiti ze-EG eziqhelekileyo ezineiankile zentsimbi engenanto. Amacwecwe ayelungile, kodwa iintloko ze-ankile zaziyingcongolo yomhlwa ebomvu kwiminyaka emithathu kulo mmandla wangaphakathi owawufumile. Ukulungiswa kwakungekho umaleko we-zinc onzima kwi-plate; ibitshintshela kwidiphu eshushu okanye iiankile ezingatyiwayo ukuze ingqinelane ngcono nesakhono segalvanic.

Ubukhulu bokwambathisa ngumgca wakho wokuqala wokuzikhusela, kodwa ayisiyonani nje kwiphepha elithile. I-5-micron yokwambathisa inokwanela ngokugqibeleleyo ukomisa, ukunyuswa kwepaneli yolawulo yangaphakathi. Zama ukuba kwiplate ebekwe kwi-concreb yekhonkrithi kwigaraji yokupaka apho kusetyenziswa i-de-icing salts, kwaye uya kujonga ukungaphumeleli kwiibusika ezimbalwa. Umgaqo wobhontsi? Kwinkonzo yangaphandle, ephakathi, ndiyathandabuza ukucacisa nantoni na engaphantsi kwe-12 microns. Nangona kunjalo, akukhona nje malunga nobukhulu obufanayo. Imiphetho, iziphelo ezisikiweyo, kunye neendawo zeweld kulapho ukusilela kuqala khona. Umboneleli olungileyo uya kuba nenkqubo elawulwayo yokwaleka kwakhona okanye ukutywina ezi ndawo emva kokwenziwa, kodwa elo linyathelo elongezelelweyo kunye neendleko ezininzi ezizama ukutsiba.

Emva koko kukho ukulungiswa kwesiseko sesinyithi. Apha kulapho wahlula khona ababoneleli abafanelekileyo kwabanengxaki. Ukuba intsimbi ayicocwanga kakuhle kwaye ihlanjululwe ngaphambi kokuhlamba i-zinc, ukunamathela kumbi. Ndikhe ndayibona i-coating igqabhuka kwaye ixobuka kumaphepha ngexesha lokuphatha, ndiyeke ukuya enkonzweni. Lukusilela onokuthi ulubone kwangoko ukuba uyayazi into omawuyijonge: inkangeleko enamachokoza kancinane okanye ukuncamathela okulambathayo kwincam echetyiweyo. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., esekwe kwi-hub enkulu ye-fastener yase-China e-Yongnian, ngokuqhelekileyo inomlinganiselo kunye nolawulo lwenkqubo yokulawula oku ngokungaguqukiyo, yiyo loo nto ukufunwa kwezinto ezivela kwiziseko zemveliso ezisekiweyo kubalulekile. Indawo yabo kufutshane neendlela ezinkulu zezothutho ezinje ngeBeijing-Guangzhou Railway ithetha ukuba bamiselwe isambuku, umgangatho osemgangathweni, hayi imisebenzi yamagcisa.

Ubume obuHlangeneyo nguKumkani

Awukwazi ukuthetha ukuqina kwepleyiti ngaphandle kokuthetha ngekhonkrithi. Lo ngowona mahluko mkhulu. I-alumina ephezulu okanye i-chloride-contaminated contaminated isigwebo sokufa kuyo nayiphi na intsimbi edibeneyo, i-electro-galvanized okanye ayikho. Imekobume yealkaline yeconcrete esemgangathweni inceda ngokwenene ukudlula i-zinc, yenze umaleko ozinzileyo ocothisa ukubola. Kodwa ikhonkrithi ayiyonto enye. Ndithathe inxaxheba kwiprojekthi ye-marine pier apho i-spec yabiza ii-electro-galvanized embeds. Yayiyintlekele eyayilindele ukwenzeka. Ukubonakaliswa kwekloridi rhoqo ukusuka kwisitshizi setyuwa kunye nokungena kwendawo ye-splash kuyoyisa amandla okubingelela e-zinc ngokukhawuleza. Kwafuneka senze uhlengahlengiso oluphakathi kweprojekthi kwi-epoxy-coated rebar kunye neentonga zeqhina ezingenastainless, kunye neepleyiti zitshintshelwe kwi-galvanized dip eshushu. Isifundo esinexabiso elikhulu kuvavanyo lokusingqongileyo.

Ufakelo umonakalo omnye umbulali cwaka. Abasebenzi bejula iipleyiti zibe ziifom, ukuhamba kuzo, okanye ukurhuqelwa iikheji zokuphinda zirhuqe phezu kwazo banokukrwela i-coat ukuya kwintsimbi engenanto. Nje ukuba ifakwe, loo mkrwelo uba yi-anode kwiseli ye-micro-galvanic, ikhawulezisa ukubola kwendawo. Ngoku ndigxininisa kumanyathelo alula okukhusela njengeteyiphu yethutyana kumacandelo afakwe imisonto okanye ndichaza ukuba iipleyiti zibekwe emva kokuba iseti yokuqala ye-rebar mat. Yongeza mhlawumbi i-5% kwixesha labasebenzi kodwa inokuphinda kabini ubomi benkonzo obusebenzayo.

Kuthekani ngokudityaniswa kwezinye iintsimbi? Apha kulapho iitshathi ze-galvanic series ziba kukufunda ngexesha lokulala. Ukudibanisa ipleyiti ye-electro-galvanized (i-zinc-coated steel) kwintsimbi yobhedu okanye umbhobho wobhedu ophantsi komhlaba ucela ingxaki. I-zinc iya kugqwala ngokukhawuleza ukukhusela ubhedu oluhloniphekileyo. Ndiyibonile le nto kwiinkxaso zoncedo lwemibhobho. Isisombululo sisodwa-ukusebenzisa i-dielectric bushings okanye i-washers ukuphula indlela yombane phakathi kweentsimbi ezingafaniyo. Lincinci, icandelo eliphantsi, elihlala lingahoywa kwiimpawu zokuqala.

Xa Ukulunga Kwanele Akukho

Kukho ixesha kunye nendawo yokufaka i-electro-galvanized embeds. Ngaphakathi, iindawo ezomileyo, iziseko zezixhobo zoomatshini apho udibaniso lukwafakwe ne-zinc? Lukhetho oluvakalayo, olunendleko. Iingxaki zivela xa isetyenziswa njengengcaciso engagqibekanga ngaphandle kokuba kutheni. Ndikhe ndaphonononga uninzi lwemizobo yolwakhiwo apho zonke izinto ezizinzisiweyo ziphawulwa ngokuba yi-EG ngenxa yokuba ibikwiinkcukacha zeprojekthi yokugqibela.

Siye saqhuba uvavanyo lokuthelekisa kwiminyaka embalwa edlulileyo, singcwaba iipleyiti zesampulu ezivela kwiinkqubo ezahlukeneyo kumgodi wovavanyo onobundlongondlongo, umhlaba ochatshazelwe yityuwa. Iisampulu ze-electro-galvanized zibonise ukulahleka okukhulu kwe-zinc kunye nesiseko sentsimbi ye-corrosion emaphethelweni kwiinyanga ezili-18. Iisampulu ezishushu zediphu zaziqala ukubonisa ipatina yezinki. Iisampulu zentsimbi? Ayitshintshanga ngokubonakalayo. Umlinganiselo weendleko wawumalunga ne-1:1.5:4. Umlinganiselo wokuqina awuzange ube mgca; kwakufana no-1:3:20 kuloo ndawo. Ityala leshishini lokuchitha ngaphezulu kwangaphambili licace gca kweso sicelo sithile.

Apha kulapho incoko yekhonkco lonikezelo iba yinyani. Ngobuninzi, iipleyiti zokuzinzisa eziqhelekileyo, umenzi onje ngeZitai Fastener (unokufumana uluhlu lwazo apha https //wwww.ziitasteners.com) iyavakala. Bavelisa kwisikali esiqinisekisa ukuhambelana kwenkqubo kumabakala asemgangathweni kunye neengubo. Kodwa kwindawo ebaluleke kakhulu okanye eyonakalisayo, kunokufuneka uhambe ngaphaya kwekhathalogu esemgangathweni-uchaza i-coating ebanzi, unyango lwe-chromate passivation emva kwe-galvanizing, okanye i-substrate yensimbi eyahlukileyo. Umbuzo ngowokuba ngaba umgca wabo wemveliso ubhetyebhetye ngokwaneleyo kwezo miyalelo yesiko, okanye ukuba ungcono kunomenzi okhethekileyo.

Iindlela zokusilela kunye nento omawuyijonge

Ukungaphumeleli kokuqina akufane kwenzeke ukuba ipleyiti iqhawuke kubini. Kukulahlekelwa ngumsebenzi. Eyona ndlela ixhaphakileyo kukuhlutha intambo. I-zinc corrodes kwimicu ye-welded studs, ukwandisa kunye nokutshixa i-nut. Ndichithe iiyure ezilusizi kwindawo enezitshixo zempembelelo kunye neetotshi ndizama ukukhulula amandongomane kwizigxina ezineminyaka emithandathu kuphela ubudala. Ukusebenzisa intlama yomsonto orhabaxa okanye ukufaka intlama ye-zinc ephezulu yokuchasana nokubamba ngexesha lofakelo kulula, ukuthomalalisa ngexabiso eliphantsi eliphantse lingabikho kwi-spec eqhelekileyo.

Enye iyancipha amandla okutsala. Njengoko ipleyiti kunye ne-studs yayo i-corrode, i-cross-section esebenzayo iyancipha. Oku kubalulekile kwii-ankile ezibaluleke kakhulu kukhuseleko ezifana neenkqubo zokukhusela ekwindla okanye ukuqinisa inyikima. Asinazo iindlela ezilungileyo ezingonakalisi zokujonga oku xa sele ifakiwe, yiyo loo nto inkcazo yokuqala kunye nophononongo lokusingqongileyo kubaluleke kakhulu. Ukuba uhlola isakhiwo esele sikhona, khangela i-rust staining elila ukusuka kwikhonkrithi ejikeleze i-embed. Olo luphawu olubaliswayo lomhlwa osebenzayo. Ngethuba ubona oko, ukulahlekelwa kwecandelo sele kubalulekile.

Ngamanye amaxesha ukusilela kubuhle. Umhlwa omhlophe (i-zinc oxide) ibala kwimiphezulu yekhonkrithi egqityiweyo. Ayisiyiyo ilahleko ekuqaleni, kodwa ikhangeleka yoyikeka kwi-facade. Oku kwenzeka rhoqo xa iipleyiti zigcinwe kwiimeko ezifumileyo ngaphambi kokuba zifakwe, zibangele ibala lokugcina elimanzi. Ingumba wokulawula umgangatho kumthengisi okanye kwindawo yokugcina impahla. Umthengisi olungileyo uya kumisa ngokufanelekileyo kwaye apakishe iipleyiti ukunqanda oku. Ukuba ufumana iipleyiti esele ebonisa indawo emhlophe, engumgubo ngokuthe ngqo ukusuka kwikhreyithi, yale. Loo nto yokukhusela sele idliwe ngokuyinxenye ngaphambi kokuba yenze umsebenzi wayo.

Isigwebo: Ukhetho olubaliweyo

Ke, ngaba ipleyiti ene-electro-galvanized embedded iqinile? Inokuba njalo, kodwa ukuqina kwayo ayisiyopropathi yangaphakathi. Yipropathi yenkqubo. Uthenga icandelo elinomgangatho wombingelelo. Ubomi bayo buxhomekeke kubundlobongela bendalo, umgangatho wesicelo sokugquma, isinyithi esichukumisayo, kunye nokunyamekela ngexesha lofakelo. Akusiyo isethi kwaye ulibale isisombululo seemeko ezinzima.

Kwiindawo ezingabalulekanga, zangaphakathi, okanye ezilawulwayo, lukhetho oluhle kakhulu lwezoqoqosho. Cacisa ubuncinci obucacileyo bokutyeba (ndingabonisana nge-12+ microns ngayo nantoni na engomiyo ngamathambo), funa isatifikethi esivela kumenzi, kwaye uqinisekise ukuba zonke izibophelelo ezidityanisiweyo zineengubo ezihambelanayo. Kwindawo engaphandle, emanzi, okanye evezwe yikloridi, kusenokwenzeka ukuba ungcono xa unyusa igophe lokuqina ukuya eshushu-diphu iigalvanized okanye ngomatshini ukugalela i-galvanizing engqindilili, eyomeleleyo ngakumbi. Kwezona zicelo zibaluleke kakhulu okanye ezonakalisayo, ixabiso eliphezulu lokuqala lokuzinzisa insimbi engenasici lukhetho olunobulumko kuphela.

Ekugqibeleni, kuhla oku: chaza indawo yenkonzo kunye nobomi obufunekayo benkonzo kuqala. Emva koko jonga kwakhona ipleyiti kunye nokudibanisa kwayo. Musa nje ukungagqibeki kwi-electro-galvanized kuba yinto yomgca wonke umntu owaziyo. Oko kucinga okungagqibekanga kuko okukhokelela ekungaphumelelini kwangaphambi kwexesha, ukufowunelwa, kunye nolungiso olubizayo. Ukuqina kukho, kodwa kuphela ukuba uyiyile.
