Ishidi eligoqwe ngensimbi kanye nensimbi eligoqwe ngensimbi kuyizinto eziyisisekelo ezindaweni eziningi zokwakha, ukukhiqiza, kanye nezimboni. Ukuqonda imibuzo evame ukubuzwa mayelana nokugoqwa ngensimbi, izincazelo ezifana ne-ASTM A653, kanye nezici zokusebenza kusiza amabhizinisi ukuthi akhethe izinto ezifanele kanye nomphakeli. Kulesi sihloko sikhuluma ngezinkinga ezivamile ezihlanganisa ukuvikelwa ekugqwaleni, izinhlobo zokugqoka, ukuqina, kanye nokuqhathaniswa kwezindleko ukuze sinikeze abaphathi bamaphrojekthi kanye namaqembu okuthenga ukucaca abakudingayo. Sizophinde sigqamise imininingwane efanele ngemikhiqizo mayelana namashidi ensimbi egoqwe ngensimbi asevele apendiwe kanye nezinketho ezinemibala, ezivame ukucaciswa ngezidingo zobuhle nokuvikela. Ekugcineni, abafundi bazothola izincomo eziwusizo zokukhetha abaphakeli njengeShandong Baiyi Steel kanye nezixhumanisi zezinsiza ezengeziwe zoku-oda kanye nokwesekwa kwezobuchwepheshe.

Yini i-galvanizing, futhi ivikela kanjani insimbi? I-galvanizing yinqubo ye-metallurgical, ngokuvamile i-hot-dip galvanizing, ehlanganisa insimbi ngesendlalelo se-zinc ukuhlinzeka ngokuvikelwa okuzidela ekugqwaleni. Abathengi bavame ukubuza ukuthi izendlalelo ze-galvanized ziqhathaniswa kanjani nezinye iziphetho ezihlukile, ukuthi uphahla lwensimbi olu-galvanized noma ishidi luzohlala isikhathi esingakanani, nokuthi yiziphi izindinganiso (njenge-ASTM A653) ezisebenza ezindaweni ezahlukene zomkhiqizo. Uhlobo lwezinto—ishidi eliyisicaba eliyi-galvanized, amakhoyili, noma amakhoyili ensimbi ye-galvanized eselipendwe kusengaphambili—kuthinta ukuphatha, ukukhiqiza, nokufaneleka kwezinhlelo ezithile. Eminye imibuzo ejwayelekile ihlanganisa umthelela wokupenda phezu kwezindawo ze-galvanized, ukugcinwa okulindelekile, nokuthi i-galvanizing yenza kanjani ezindaweni ezisogwini noma zezimboni.

Kunezindlela eziningana zokugalvanize ezisetshenziselwa ukukhiqiza amashidi agalvanize kanye nensimbi egcwalisiwe, lapho i-hot-dip galvanizing iyona esetshenziswa kakhulu emikhiqizweni yesakhiwo namashidi. I-hot-dip galvanizing idala ubudlelwano be-metallurgical phakathi kwe-zinc nensimbi, ikhiqize isembozo esiqinile esihlangabezana namazinga aziwayo njenge-ASTM A653 yamashidi ensimbi anesembozo. Abahlinzeki bangase futhi banikele ngezinye izindlela ezifana ne-electro-galvanized noma i-zinc-aluminum (Galvalume), ezinokubukeka okuhlukile kanye nezici zokusebenza. Amakhoyili ensimbi agcwalisiwe agcwalisiwe kanye nensimbi enemibala eyenziwe ngombala yengeza isembozo se-organic phezu kwesendlalelo se-zinc, ihlanganisa ukumelana nokugqwala nezinketho zobuhle ezinhlelweni zamaruli nezokwakheka. Ukuqonda isisindo sesembozo (isibonelo, i-G30, i-G60, i-G90 emagameni e-A653) kubalulekile ekucaciseni isikhathi sokuphila kanye nokuhlanganiswa kwewaranti kwensimbi egcwalisiwe yophahla noma amashidi esakhiwo.

I-sheet ye-galvanized isetshenziswa ezinhlelweni ezahlukahlukene ezihlanganisa uphahla, ukugqoka izindonga, imibhobho ye-HVAC, amaphaneli angaphakathi ezimoto, nemishini yezolimo. Ezintweni zangaphandle ezifana nophahla lwensimbi olu-galvanized, kufanele kucatshangelwe kokubili isigaba sokugqoka i-zinc (ASTM A653) nanoma yiluphi uhlelo lokudweba olufakwe phezu kwayo ukuze kuqinisekiswe ukusebenza kwesikhathi eside ezimweni zemvelo zasendaweni. Amakhoyili ensimbi ye-galvanized adwebelwe ngaphambili athandwa kakhulu uphahla nasezindongweni zezakhiwo ngoba enza lula ukuqedwa endaweni futhi asheshise ukufakwa ngenkathi ehlinzeka ngokungaguquguquki kombala. Abakhiqizi abafana neShandong Baiyi Steel bakhiqiza imikhiqizo ehlukahlukene ye-galvanized ne-pre-painted eyenzelwe lezi zinhlelo, banikeza ngokwenza ngokwezifiso ubukhulu, isisindo sokugqoka, nezinhlelo zemibala ukuze kuhlangatshezwane nezidingo ezithile zephrojekthi. Ukukhetha i-substrate efanele, ukugqoka, nokwelashwa okulandelayo kuzokwehlisa izindleko zesikhathi sokuphila futhi kuqinisekise ukuthi umhlangano oqediwe uhlangabezana nezidingo zobuhle nemithetho.

Impilo yesevisi yamashidi agalelwe i-zinc ne-metal yensimbi agalelwe i-zinc incike ekujiyeni kwe-coating (izigaba ze-ASTM A653), ukuchayeka emvelweni, nezinqubo zokugcinwa. Ezindaweni zasemakhaya noma ezimnene, i-zinc coating ecaciswe kahle ihlanganiswe nokuqedwa okupendwe kungahlala iminyaka eminingi; ezindaweni ezisogwini noma ezinezimboni zamakhemikhali, kunconywa izisindo eziphakeme ze-coating nezigaba ezikhethekile zopende. Ukuhlola njalo, ukulungiswa okusheshayo kwemihuzuko, nemininingwane efanele yomklamo (ukudonsa amanzi, ukuhlukaniswa nezinsimbi ezihlukile) kuzokwandisa impilo yesevisi kakhulu. Lapho kusetshenziswa amashalofu ensimbi agalelwe i-zinc apendwe kusengaphambili, i-organic coating ihlinzeka ngokuvikelwa okwengeziwe kwe-barrier nokumelana ne-UV, okwandisa kakhulu impilo lapho icaciswe kahle. Abakhiqizi bavame ukuhlinzeka ngemibono yempilo elindelekile nolwazi lwe-warranty olususelwa ezinhlelweni ze-coating ezihlolwe nezigaba zokuchayeka zasendaweni.

Uku-galvanize kunikeza ukuvikelwa okuzidela: i-zinc iyabola phambili kunesisekelo sensimbi, ivikela imiphetho eyimboziwe nezindawo ezilimele kancane. Kuyasebenza kakhulu ngokumelene nokubola okufanayo kodwa akusebenzi kangako ngokumelene nokubola okuthile ezindaweni ezinomswakama obanjisiwe noma ama-chloride anolaka atholakala ezindaweni zasolwandle, ngaphandle kokuthi kusetshenziswe izisindo eziphakeme zokugqoka noma izigqoko ezengeziwe. Kwizicelo ezidinga ukuvikelwa okuthuthukisiwe, abaklami bavame ukucacisa i-galvanized kanye upende (ishidi le-galvanized elipendwe ngaphambili) noma izigqoko ze-zinc-aluminum ukuze kuthuthukiswe ukumelana nezinto ezithile ezibola. Ukuqonda ubungozi obuqondile bokubola esizeni sakho nendima yemigomo yokuklama kubalulekile ekukhetheni umkhiqizo we-galvanized ofanele kanye nohlelo lokugcinwa.

Izindleko zokuqala zensimbi yensimbi ye-galvanized ngokuvamile ziyancintisana uma kuqhathaniswa ne-stainless steel nezinye izinto zokugqoka ezikhethekile, ngenkathi zinikeza izinzuzo ezibalulekile zokusebenza isikhathi eside uma kuqhathaniswa nensimbi engagqokwanga ngenxa yokuncipha kokugcinwa kanye nokuphila isikhathi eside. Amakhoyili ensimbi ye-galvanized agcwaliswe ngaphambili engeza izindleko zokuqala zesistimu yopende kodwa anganciphisa isikhathi sokufaka nokuvuselela kabusha, anciphise izindleko zokuba nazo sezizonke zamarrufu nezingxenye zangaphandle. Izinketho zokucaciswa ezifana nesisindo sokugqoka nge-ASTM A653 nohlobo lwesistimu yopende zizodala umehluko wentengo, futhi abathengi kufanele bacabangele izindleko zokuphila konke kunokuba intengo yokuthenga impahla kuphela. Ukusebenza nabaphakeli abanolwazi njengeShandong Baiyi Steel kungasiza ekulinganiseni izindleko nokusebenza ngokukhethwa kwezinto ezifanele nokwenza ngokwezifiso.

Izendlalelo ezifakwe i-galvanized zigcina ukuvikelwa kwesakhiwo ezingeni lokushisa eliphakathi eliphakeme, kodwa ezingeni lokushisa eliphezulu kakhulu i-zinc ingahlupheka ngokudifuzwa, ukugqwala, nokuziphatha okubuthakathaka. Ezinhlelweni ezijwayele ukuba ngaphezu kuka-200°C, izendlalelo ezifakwe i-galvanized zingase zingafaneleki futhi izendlalelo ezisezingeni lokushisa eliphezulu noma insimbi engagqwali zingacaciswa. Ezinhlelweni eziningi zokwakha, izindlu, nezimboni ezijwayelekile, ishidi elifakwe i-galvanized lisebenza kahle ezingeni lokushisa elilindelekile, ikakhulukazi uma lihambisana nezendlalelo zopende ezifanele ukuze kuvikelwe ukushisa ne-UV. Ukuchayeka ekushiseni okuthile kwephrojekthi kufanele kubuyekezwe nabachwepheshe bezinto zokwakha nabathengisi ukuze kuqinisekiswe ukusebenza kwesikhathi eside nokuhambisana nezidingo zokuphepha.

Ukukhetha umphakeli onokwethenjelwa wamashidi agalvanized namakoyili ensimbi agalvanized agalelwe umbala kubalulekile ukuze kufezekiswe ukusebenza okucacisiwe nokulethwa ngesikhathi. Hlolani abaphakeli ngokusekelwe emandleni okukhiqiza, ukulawula ikhwalithi (isibonelo, ukuhlolwa kwesisindo sokugqoka), ukuthobela izindinganiso ezifana ne-ASTM A653, kanye nekhono lokunikeza ngokwezifiso njengokusika, izinsizakalo zokusika-ubude, nemibala yomdwebo yangokwezifiso. I-Shandong Baiyi Steel iyisibonelo somkhiqizi ohlangene ovundlile onikeza uhla lwezixazululo ezi-galvanized, i-aluminum-zinc, nezi-color-coated, futhi banikeza ukwesekwa kwezobuchwepheshe, ukwenza ngokwezifiso, kanye nenkonzo yangemva kokuthengisa kumakhasimende omhlaba wonke. Cela izitifiketi zomshini, amaphaneli wesampula, namashidi enemininingwane yezobuchwepheshe ukuze uqinisekise izinhlelo zokugqoka kanye nezakhiwo zezinto ngaphambi kokuphaka ama-oda amakhulu. Ukuqhathanisa izikhathi zokuholela, amandla ezokuthutha, nemibandela yewaranti kuzosiza ukunciphisa ubungozi bephrojekthi futhi kuqinisekise ukuhlinzekwa okungaguquki.

Ukuklama nokufakwa okufanele kwandisa impilo yesevisi yezinhlelo zophahla lwensimbi olugcotshwe nge-zinc nezinye izicelo zamashidi agcotshwe nge-zinc. Klama ukuze kube nokuconsa, gwema izindawo lapho amanzi angakwazi ukuhlala khona, futhi uhlukanise insimbi egcotshwe nge-zinc nezinto ezingahambisani ezibangela ukugqwala kwe-galvanic. Ngesikhathi sokufakwa, nciphisa umonakalo womshini ongqimbeni ye-zinc bese uthinta ngokushesha noma yimiphi imihuzuko ngezinto ezifanele zokulungisa ezinothile nge-zinc. Ukuhlola njalo ukuze kususwe imfucumfucu, kuhlanzwe imisele, futhi kuxazululwe izindawo ezilimele kuzogcina insimbi egcotshwe nge-zinc isebenza njengoba ihloselwe. Uma usebenzisa amakhoyili agcotshwe nge-zinc asevele apendiwe, landela imihlahlandlela yomkhiqizi yokubamba nokubumba ukuze uvimbele upende ukuthi ungahlukaniseki futhi ugcine ubuqotho bokugqoka; ukusebenza nabafaki nabathengisi abanolwazi kunciphisa izinkinga zasensimini futhi kuthuthukisa ukubukeka kokugcina.

I-sheet negalvanized steel metal kuhlale kuyizinketho ezisebenzayo, ezingabizi kakhulu kumaphrojekthi amaningi lapho kucaciswe futhi kufakwe kahle. Izinto ezibalulekile zihlanganisa ukukhetha inqubo efanele yokugalvanize kanye nesisindo sokugqoka (amabanga e-ASTM A653), ukunquma ukuthi ama-coils egcwaliswe ngopende wangaphambili anenzuzo yini esicelweni sakho, nokubambisana nomphakeli ohlinzeka ngekhwalithi eqinisekile nokusekelwa kwezobuchwepheshe.
