Ukuqalisa
Endaweni yokwakha nokukhiqiza, ukuqina kwezinto ezibonakalayo ezivela ezimweni zezulu ezinokhahlo zibaluleke kakhulu. Izakhiwo zihlala zivezwa ezintweni ezinjengemvula, iqhwa, umswakama, kanye nokungcola okungahlehlisa ubuqotho babo ngokuhamba kwesikhathi. Indwangu eyodwa eye yasukuma isivivinyo sesikhathi sokumelana nale miphumela eyingozi yishidi lensimbi elishisayo elishisayo. Le ehlukile yensimbi inikezela ngesixazululo esiqinile sezimboni esifuna ukuthembeka emikhiqizweni yabo. Inqubo ye-galvanization ithuthukisa ikhono lensimbi lokumelana nezimo ezilonakalisayo, okwenza kube yisinqumo esihle se Amashidi ensimbi enziwe ngezicelo ezahlukahlukene.
Ukuqonda amashidi ensimbi acwebezelayo
Amashidi e-hot dippled galvanized yensimbi akhiqizwa ngensimbi ecwilisiwe ibe yi-zinten zinc, okuholele ekuhlolweni kwe-metallurgical phakathi kwe-zinc nensimbi. Le nqubo idala isakhiwo esinezingqimba ezintathu ezibandakanya umgogodla wensimbi, ungqimba oluphakathi nendawo, kanye ne-zinc coating yangaphandle. I-zinc isebenza njengesithiyo esivikelekile, ivimbela izinto ezilimazayo ekufinyeleleni i-substrate yensimbi. I-Metallurgical Bond iqinisekisa ukuthi ukuhlanganiswa kuhlala isikhathi eside futhi kumelana nomonakalo owenziwe ngomshini ngesikhathi sokuphatha kanye nenkonzo.
Inqubo ye-galvanization
Inqubo ye-Galvanization ifaka izinyathelo ezibucayi eziningana zokuqinisekisa ikhwalithi ephezulu yokuhlangana. Ekuqaleni, amashidi ensimbi afaka ukulungiswa okungaphezulu, okubandakanya ukuhlekisa, ukukha, kanye nokukhipha ukususa ukungcola kanye no-oxides. Lokhu kulungiswa kubalulekile ekufezekiseni umfaniswano kanye no-zinc ungqimba. Ngemuva kokulungiselela, amashidi aqothulwe kubhavu we-zingn zinc afudumele cishe ama-450 ° C (842 ° F). Lapho uhoxa, i-zinc iphendula ngensimbi ukwakha izingqimba ezivikelayo. Amashidi aphonswe futhi ahlolwe ukuqina nokuqina.
Izindlela zokugqwala kanye nesimo sezulu
I-Corrosion iyinqubo yemvelo eyenzeka lapho ama-Metals ephendula ngezinto zezemvelo, eholela ekunciphiseni ngokwenyama. Ezimweni zezulu ezinzima, izici ezinjengomswakama, umoya-mpilo, ukuhlukahluka kokushisa, kanye nokungcola kusheshisa amanani okugqwala. Isibonelo, ezindaweni ezisogwini, isifutho sikasawoti sabethula ama-chlorides awonaka kakhulu ngensimbi. Izifunda zezimboni kungenzeka zibe namazinga aphakanyisiwe we-sulphur dioxide, efaka isandla emvuleni ye-acid, okubuye kwandise ukugqwala. Ukuqonda lezi zinqubo kubalulekile ekukhetheni izinto ezingamelana nezimo ezinolaka ezinjalo.
Insimbi ye-galvanized imelana kanjani nokugqwala
Ukumelana okwenziwe ngensimbi okuhlukile kokugqwala kweziqu ezivela ezinhlakeni ezivikelayo ze-zinc coating. I-zinc isebenza njengesithiyo esingokomzimba, ukuvikela insimbi eyisisekelo kusuka kumswakama nangomoya-mpilo. Ngaphezu kwalokho, i-zinc inekhono eliphakeme le-electrochemical kunensimbi, elivumela ukuthi lisebenze. Uma ukuhlanganiswa kuklwebekile noma kulimele, i-zinc ithanda izimoto ezikhethekile, ukuvikela izindawo ezinsimbi eziveziwe, into ebizwa ngokuthi yiGalvanic noma iCathodic Protection.
Ukuvikelwa kwesithiyo
Ungqimba lwangaphandle lwe-zinc lunikeza ngesithiyo esingenakufinyeleleka ezintweni zezemvelo. Lesi sivimbelo sivimbela izinto ezilimazayo ekuxhumaneni nensimbi engaphezulu. Ubuqotho balesi singqimba bubaluleke kakhulu ekulweni isikhathi eside, ngoba buyehlisa kakhulu inqubo yokugqwala. Izakhiwo ezinama-adhesing ze-zinc coating ziqinisekisa ukuthi zihlala ziqinile ngisho nangaphansi kwezingcindezi zemishini.
Ukuvikelwa kwe-galvanic
Ezimweni lapho uZinc ungqimba ubekekiswe khona, ukuvikelwa kweGalvanic kuyaqala ukuzodlalwa. Ubudlelwano be-electrochemical phakathi kwe-zinc nensimbi bubangela i-zinc ku-oxidize ngokukhethekile, ngaleyo ndlela ulondoloze insimbi. Lokhu kuziphatha okuzihlazisayo kunwebeka isikhathi sokuphila kwengxenye yensimbi, okwenza amashidi wensimbi eshisayo acwebezelwe alungele ikakhulukazi izimo ezinokhahlo.
Ukusebenza ezindaweni ezinokhahlo
Amashidi wensimbi eshisayo afakiwe ahlolwe futhi afakazelwe ukuthi asebenze kahle ezimweni ezahlukahlukene ezinzima. Ukuguquguquka kwabo kubenza babe yinto ethandwayo emikhakheni eminingi.
Izimo Ezisogwini
Ezifundeni ezisogwini, ukuba khona komoya osawoti-laden kukhulisa kakhulu ubungozi bokugqwala. Amashidi ensimbi enziwe nge-galvanized anikezela ukuvikelwa okunwetshiwe ngenxa yokuhlanganisa i-zinc coating yabo. Ucwaningo lukhombisile ukuthi i-zinc under ingamelana nemiphumela elonakalisayo yama-chlorides, ihlinzeka isikhathi sokuphila esifinyelela eminyakeni engama-75 kwezinye izimo. Lokhu kuqina kubenza balungele ingqalasizinda yasolwandle, njengama-docks, amabhuloho, kanye nezakhiwo zasogwini.
Izindawo Zezimboni
Izindawo zezimboni zivame ukuba nokugxila okuphezulu kokungcola okufana ne-sulphur dioxide kanye ne-nitrogen oxide, okuholela emvuleni ye-acid. Ukumelana kwensimbi kwe-galvanized ezimweni ze-acid kuqinisekisa ukuthi izakhi zezinhlelo zigcina ubuqotho bazo ngokuhamba kwesikhathi. Ukusebenza okungaguquki kulezo zimo zakwa-Adrossheres anolaka kwenza amashidi ensimbi ahleliwe abhekabheka amafektri kanye nokufakwa kwezimboni.
Izindawo zasemakhaya
Ezimweni zasemakhaya, amashidi ensimbi enziwe nge-galvanized avezwa emaphethini wesimo sezulu ahlukahlukene, kufaka phakathi ukuguquguquka komswakama ophezulu nokushintshashintsha kwezinga lokushisa. I-zinc coating ivikela ngempumelelo ukugqwala nokugqwala, okwenza ilungele izakhiwo zezolimo, uthango kanye nemishini. Ukuphila isikhathi eside kwensimbi ye-galvanized kulezi zilungiselelo kunciphisa isidingo sokufakwa kabusha kanye nokulungiswa.
Isikhathi eside nokulungiswa
Enye yezinzuzo ezibalulekile zamashidi wensimbi eshisayo e-galvanized galvanized impilo yabo ende yokuphila ngokulungiswa okuncane. Isendlalelo se-zinc evikelayo singanikeza ukumelana nokugqwala kwamashumi eminyaka, kuya ngemvelo nobukhulu be-coating. Ukuhlola okujwayelekile kuvame ukwanele ukuqinisekisa ukuthi okuqukethwe kuhlala kusesimweni esihle. Lapho ukulungiswa kudingeka, kuvame ukuqondile, okubandakanya ukuthinta kwe-zinc coating ukulungisa noma yiziphi izindawo ezilimele.
Izinzuzo Ezingokomnotho Nezosizo
Ngokombono wezomnotho, amashidi ensimbi enziwe nge-galvanized anikela ngokonga izindleko esikhathini eside. Ukutshalwa kwezimali kokuqala kususwe izindleko ezincishisiwe zokugcina kanye nempilo yenkonzo eyengeziwe. Lokhu kubenza kube yisixazululo esisebenzayo sabakhiqizi, abasabalalisi kanye nabasebenzisi bokugcina. Ukuguquguquka kwama-shithilethi ensimbi enziwe nge-galvanized kuvumela ukuthi zisetshenziswe ezinhlobonhlobo zezicelo, ezivela ezingothweni zezimoto ezintweni ezakhiwe ngezakhiwo.
Izicelo kuyo yonke imboni
Ukusetshenziswa kwamashidi ensimbi egayiselelwe achithe izimboni eziningi. Ekwakheni, babalulekile ophahleni, ekuqondeni, kanye nokufakelwa ngenxa yamandla abo nokumelana nesimo sezulu. Imboni yezimoto isebenzisa amaphaneli omzimba nezinto ezingaphansi, ukuzuza ekubekezeleni kwazo kanye nezindawo ezilula. Ngokwengeziwe, umkhakha wamandla usebenzisa insimbi eyenziwe ngotshani emibhoshongweni yokudlulisela kanye nama-turbines womoya, lapho ukumelana nezici zezemvelo kubalulekile.
Ubuchwepheshe obusafufusa eGalvanization
Intuthuko kubuchwepheshe be-galvanization iyaqhubeka nokuthuthukisa ukusebenza kwamashidi ensimbi. Amasu amasha anjenge-bacting zinc anezinye izinsimbi ezinjenge-aluminium ne-magnesium ziholele ekuphikisweni kokugqwala okuthuthukile. Lezi zimbozo zesizukulwane esilandelayo zinikeza ukuvikela okuphakeme ezindaweni ezinolaka ngokwengeziwe, kwandisa ukusetshenziswa okungenzeka kwensimbi ye-galvanized.
Ukucatshangelwa Kwezemvelo
Ukusimama kuyinto ebaluleke kakhulu ekukhetheni kwezinto ezibonakalayo. Insimbi ye-Galvanized yi-100% esebenza kabusha, futhi inqubo ye-galvanization ivele yaba nobungane ngokwemvelo. Izitshalo zanamuhla zisebenzisa izindlela zokunciphisa ukuphuma nokuvuselela i-banc neminye imikhiqizo. Lokhu kuzibophezela ebuphathi bezemvelo kwenza amashidi e-hot dippled steel galvanizer
Ukugcina
Ukuqina kwamashidi ashisayo acwebezelayo ngezimo zezulu ezinokhahlo kuwukuvuselela ubunjiniyela babo kanye nesayensi yezinto ezibonakalayo Excellence. Ukuhlanganiswa kokuvikelwa kwesithiyo nokuvikelwa kwe-galvanic okunikezwe yi-zinc coating kuqinisekisa ukuqina nokuthembeka kwesikhathi eside. Ukuze uthole amafektri, abasabalalisi kanye nezimboni ezifuna izinto ezinikela ngokusebenza okuphezulu ngokulungiswa okuncane, amashidi ensimbi enziwe nge-galvanized amelela ukukhetha okuhle. Irekhodi labo elifakazelwe, elihambisana nentuthuko kwezobuchwepheshe, iyaqhubeka nokubenza basebenze ezindaweni ezifunwa namuhla. Emukela amashidi ensimbi enziwe ngokwakha futhi ekwakhiweni akugcini nje ngokukhathazeka okuxakekile ngokushesha kodwa futhi kube nomthelela ezenzweni ezizinzileyo nezingabizi.
