Isingeniso
Emkhakheni wokwakha nokukhiqiza, ukuqina kwezinto ezibonakalayo ngokumelene nezimo zezulu ezinzima kubaluleke kakhulu. Izakhiwo zihlala zichayeka ezintweni ezifana nemvula, iqhwa, umswakama, nezinto ezingcolisayo ezingabeka engcupheni ubuqotho bazo ngokuhamba kwesikhathi. Okunye okuye kwamelana nesikhathi eside nokumelana nale miphumela elimazayo yishidi lensimbi elicwilisiwe elishisayo. Lokhu okuhlukile kwensimbi kunikeza isixazululo esiqinile sezimboni ezifuna ukuphila isikhathi eside nokuthembeka emikhiqizweni yazo. Inqubo yokufaka uthayela ithuthukisa ikhono lensimbi lokukwazi ukumelana nezindawo ezonakalisayo, ikwenze kube ukukhetha okuhle Amashidi Ensimbi Akhanyiswe asetshenziswa ezinhlelweni ezihlukahlukene.
Ukuqonda Amashidi Ensimbi Afakwe Ngamanzi Ashisayo
Amashidi ensimbi acwilisiwe ashisayo akhiqizwa ngokucwilisa insimbi ku-zinc encibilikisiwe, okuholela kusibopho sensimbi phakathi kwezinki nensimbi. Le nqubo idala isakhiwo esinezingqimba ezintathu esihlanganisa umgogodla wensimbi, ungqimba lwe-intermetallic, kanye ne-zinc yangaphandle enamathela. I-zinc isebenza njengesithiyo esivikelayo, esivimbela izinto ezibolayo ukuthi zingafinyeleli ku-substrate yensimbi. Ibhondi ye-metallurgical iqinisekisa ukuthi ukunamathela kuqinile futhi amelana nokulimala komshini ngesikhathi sokuphatha nesevisi.
Inqubo Ye-Galvanization
Inqubo ye-galvanization ihilela izinyathelo ezimbalwa ezibalulekile zokuqinisekisa ikhwalithi yokugqoka efanele. Ekuqaleni, amashidi ensimbi alungiselwa indawo engaphezulu, okuhlanganisa ukukhishwa, ukucosha, nokuguquguquka ukuze kukhishwe ukungcola nama-oxide. Lokhu kulungiselelwa kubalulekile ukuze kuzuzwe ungqimba lwezinc olufana nolunamathelayo. Ngemva kokulungiselela, amashidi acwiliswa kubhavu we-zinc encibilikisiwe eshisiswe cishe ku-450°C (842°F). Lapho ihoxiswa, i-zinc ihlangana nensimbi ukuze yakhe izendlalelo zokuzivikela. Amashidi abe esepholiswa futhi ahlolwe ukushuba nokuvumelana.
Izindlela Zokugqwala Nesimo Sezulu
Ukugqwala kuyinqubo engokwemvelo eyenzeka lapho izinsimbi zihlangana nezakhi zemvelo, okuholela ekulimaleni kwezinto ezibonakalayo. Ezimweni zesimo sezulu esibi, izinto ezinjengomswakama, umoya-mpilo, ukuhlukahluka kwezinga lokushisa, nezinto ezingcolisayo zisheshisa izinga lokugqwala. Ngokwesibonelo, ezindaweni ezisogwini, isifutho sikasawoti singenisa ama- chloride agqwala kakhulu ensimbi. Izifunda zezimboni kungenzeka zibe namazinga aphakeme e-sulphur dioxide, okunomthelela emvuleni ene-asidi, ebhebhethekisa ukugqwala. Ukuqonda lezi zindlela kubalulekile ekukhetheni izinto ezingamelana nezimo ezinolaka.
Indlela Insimbi Eyisithako Emelana Ngayo Nokugqwala
Ukumelana okuyingqayizivele kwensimbi engagqwali ukugqwala kubangelwa izici zokuvikela ze-zinc coating. I-zinc isebenza njengesithiyo esingokomzimba, ivikela insimbi engaphansi kumswakama nomoya-mpilo. Ngaphezu kwalokho, i-zinc inamandla aphezulu e-electrochemical kunensimbi, eyivumela ukuthi isebenze ngokuzidela. Uma i-coating iklwejwa noma yonakele, i-zinc ikhetha ukugqwala, ivikele izindawo zensimbi eziveziwe, into eyaziwa ngokuthi i-galvanic noma i-cathodic protection.
Ukuvikelwa Kwezithiyo
Ungqimba lwangaphandle lwe-zinc lunikeza umgoqo ongangenisi ezintweni zemvelo. Lesi sivimbelo sivimbela izinto ezibolayo ukuthi zingathintani nendawo yensimbi. Ubuqotho balolu ungqimba bubalulekile ekuqineni kwesikhathi eside, njengoba kunciphisa kakhulu inqubo yokugqwala. Izakhiwo zokunamathela ze-zinc ziqinisekisa ukuthi zihlala ziqinile ngisho nangaphansi kwengcindezi yemishini.
Ukuvikelwa kweGalvanic
Ezimweni lapho ungqimba lwe-zinc lusengozini, ukuvikelwa kwe-galvanic kuyaqala. Ubudlelwano be-electrochemical phakathi kwe-zinc nensimbi bubangela ukuba i-zinc i-oxidize ngokukhethayo, ngaleyo ndlela ilondoloze insimbi. Lokhu kuziphatha kokuzidela kunweba isikhathi sokuphila sengxenye yensimbi, okwenza amashidi ensimbi acwiliswe ashisayo afanelekele ikakhulukazi izindawo ezinokhahlo.
Ukusebenza Ezimweni Ezinzima
Amashidi ensimbi afakwe uthayela ashisayo ahloliwe futhi afakazelwa ukuthi asebenza kahle kakhulu ezimeni ezihlukahlukene ezinzima. Ukuzivumelanisa nezimo kuzenza zibe izinto ezithandwayo emikhakheni eminingi.
Imvelo Yasogwini
Ezifundeni ezisogwini, ukuba khona komoya ogcwele usawoti kwandisa kakhulu ingozi yokugqwala. Amashidi ensimbi anama-galvanized anikeza ukuvikeleka okunwetshiwe ngenxa yokunamathela kwawo okuqinile kwe-zinc. Ucwaningo luye lwabonisa ukuthi ungqimba lwezinc lungamelana nemiphumela elimazayo yama-chloride, lunikeze isikhathi sokuphila esingafika eminyakeni engama-75 kwezinye izimo. Lokhu kuqina kuzenza zilungele ingqalasizinda yasolwandle, njengezikhumulo zemikhumbi, amabhuloho, nezakhiwo ezingasogwini.
Indawo Yezimboni
Izindawo zezimboni zivame ukuba nokugxilwa okuphezulu kokungcola okufana ne-sulphur dioxide nama-nitrogen oxides, okuholela emvuleni ene-asidi. Ukumelana nensimbi egayiwe ezimweni ezine-acidic kuqinisekisa ukuthi izingxenye zesakhiwo zigcina ubuqotho bazo ngokuhamba kwesikhathi. Ukusebenza okungaguquguquki emkhathini oshubile kangaka kwenza amashidi ensimbi abeluleka kakhulu ezimbonini nasekufakweni kwezimboni.
Izindawo Zasemakhaya
Ezindaweni zasemakhaya, amashidi ensimbi athathiwe achayeka ezimeni zesimo sezulu ezihlukene, okuhlanganisa umswakama ophezulu kanye nokushintshashintsha kwezinga lokushisa. I-zinc enamathelayo ivikela ngempumelelo ukugqwala nokugqwala, ikwenze ifaneleke izakhiwo zezolimo, uthango, nezinto zokusebenza. Ukuphila isikhathi eside kwensimbi yama-galvanized kulezi zilungiselelo kunciphisa isidingo sokushintshwa nokugcinwa njalo.
Ukuphila Isikhathi Eside Nokunakekela
Enye yezinzuzo ezibalulekile zamashidi ensimbi acwiliswe ashisayo impilo yawo ende yesevisi enokunakekelwa okuncane. Isendlalelo se-zinc esivikelayo singanikeza ukumelana nokugqwala amashumi eminyaka, kuye ngendawo ezungezile nokuqina kwento enamathelayo. Ukuhlola okuvamile ngokuvamile kwanele ukuqinisekisa ukuthi okokusebenza kuhlala kusesimweni esihle. Uma ukunakekelwa kuyadingeka, ngokuvamile kuqondile, okubandakanya ukuthintana kwe-zinc coating ukulungisa noma yiziphi izindawo ezilimele.
Izinzuzo Zezomnotho Nezingokoqobo
Ngokombono wezomnotho, amashidi ensimbi anezinsimbi anikeza ukonga izindleko esikhathini eside. Ukutshalwa kwezimali kokuqala kunxeshezelwa izindleko zokulungisa ezincishisiwe kanye nempilo yesevisi eyandisiwe. Lokhu kubenza babe yisixazululo esingabizi kakhulu kubakhiqizi, abasabalalisi, kanye nabasebenzisi bokugcina. Ukuguquguquka kwamashidi ensimbi anama-galvanized kuvumela ukuthi asetshenziswe ezinhlobonhlobo zezicelo, kusukela ezingxenyeni zezimoto kuya ezingxenyeni zesakhiwo ezakhiweni.
Izicelo Kuzo zonke Izimboni
Ukusetshenziswa kwamashidi ensimbi athathiwe kuhlanganisa izimboni eziningi. Ekwakhiweni, zibalulekile ekufuleleni, ekuhlanganisweni, nasekufakeni amafreyimu ngenxa yamandla azo kanye nokumelana nesimo sezulu. Imboni yezimoto iwasebenzisela amaphaneli omzimba kanye nezingxenye zenqola yangaphansi, ehlomula ngokuqina kwawo kanye nezakhiwo ezingasindi. Ukwengeza, umkhakha wamandla usebenzisa insimbi enama-galvanized emibhoshongweni yokudlulisela kanye nezinjini zomoya, lapho ukumelana nezimo zemvelo kubalulekile.
Emerging Technologies in Galvanization
Ukuthuthuka kobuchwepheshe bokwenza uthayela kuyaqhubeka nokuthuthukisa ukusebenza kwamashidi ensimbi. Amasu amasha anjengokusebenzisa i-zinc nezinye izinsimbi njenge-aluminium ne-magnesium aholele ekumelaneni nokugqwala okuthuthukisiwe. Lezi zinhlobonhlobo zesizukulwane esilandelayo zinikeza ukuvikeleka okuphezulu ezindaweni ezinolaka nakakhulu, okunweba ukusetshenziswa okungase kube khona kwezinsimbi.
Ukucatshangelwa Kwemvelo
Ukuzinza kuyisici esibaluleke kakhulu ekukhetheni izinto ezibonakalayo. Insimbi engaphekiwe ingaphinda igaywe kabusha ngo-100%, futhi inqubo yokufaka uthayela isishintshile ukuze ivumelane nemvelo. Izitshalo zesimanje zisebenzisa izinyathelo zokunciphisa ukukhishwa kwekhabhoni futhi zisebenzise kabusha i-zinc neminye imikhiqizo ekhiqizwayo. Lokhu kuzibophezela ekunakekeleni imvelo kwenza amashidi ensimbi acwiliswe ashisayo abe yisinqumo esinesibopho samaphrojekthi aqaphela imvelo.
Isiphetho
Ukuqina kwamashidi ensimbi acwiliswe ashisayo esimweni sezulu esibi kuwubufakazi bobunjiniyela babo nesayensi yezinto ezibonakalayo. Ukuhlanganiswa kwesithiyo kanye nokuvikelwa kwe-galvanic okuhlinzekwa yi-zinc coating kuqinisekisa ukuqina nokuthembeka kwesikhathi eside. Emafekthri, abasabalalisi, kanye nezimboni ezifuna izinto ezihlinzeka ngokusebenza okuphezulu ngokulungiswa okuncane, amashidi ensimbi agqamile amele ukukhetha okuhle. Irekhodi labo eliqinisekisiwe, elihambisana nentuthuko kwezobuchwepheshe, liyaqhubeka nokubenza bafaneleke ezindaweni zanamuhla ezinzima. Ukwamukela Amashidi Ensimbi Ethathiwe ekwakheni nasekukhiqizeni akugcini nje ngokubhekana nezinkinga ezikhona ngokushesha kodwa futhi kunomthelela emikhubeni eqhubekayo neyonga imali.
