I-iron nensimbi kuyizinsimbi ezimbili ezisetshenziswa kakhulu emhlabeni. Lezi zinto ezimbili zinezakhiwo ezikhethekile ezizihlukanise nabanye, futhi ubuchwepheshe kanye nezinqubo zanamuhla zithuthukise ama-subsets amasha - i-cast iron nensimbi yensimbi ne-galvanized. Lezi zinhlobonhlobo zokusetshenziswa ezimbonini eziningi, amakhaya, nezinhlelo zendle. Le ndatshana izochaza umehluko phakathi kwensimbi ye-Iron vs Galvanized, bese uxoxa ngokuthi lo mehluko uthinta kanjani ukusetshenziswa kwazo kumapayipi kanye nezinhloso zokupaka kwendle.
Ukwakheka
Ingxenye eyinhloko ye-cast iron ivela ku-iron ores. Lapho-ke, i-alloy eyenziwe ngensimbi, ikhabhoni, no -lilicon. Imvamisa yenziwa nge-2 kuye ku-4% yekhabhoni, kanye nezingxenye ezincane ze-silicon. Ukungcola okufana nabanganengane, isibabule, ne-phosphate kwesinye isikhathi kukhona e-cast aron. Lezi zinto ezengeziwe zivame ukuba zincanyana kakhulu ukuthi zithinte izakhiwo zensimbi.
Insimbi eyenziwe nge-carbon noma ngensimbi ecacile yekhabhoni, okuyi-alloys yensimbi. I-carbon yensimbi yenziwa ngezinto ezimbili: i-iron nekhabhoni. Ezinye izinsimbi ezingaba khona kuleli alloy zingama-manganese, silicon, nethusi. Imvamisa bahlanganisa imali engaphansi kwe-0,60% ye-alloy, okusho ukuthi imiphumela yabo kwizakhiwo ze-alloy ayinakwa.
Amalungiselelo
I-cast iron ilungiselelwe kusetshenziswa isithando somlilo futhi yenziwe nge-avoys ye-iron-carbon noma i-iron yengulube. Ngale nqubo, i-Iron ye-cast yakhiwa ngqo kusuka ku-molten Metal. Ukungcola okushiwo kungashiswa phakathi nalesi sigaba. Kodwa-ke, i-carbon nayo ingashisa ngendlela efanayo, okufanele ithathelwe indawo ngaphambi kokuthi kuqedwe ifomu lensimbi ye-Iron. I-Spot Iron izoba nephutha uma ingenawo amakhabhoni nezinto ze-silicon. Ngemuva kwesithando somlilo, i-cast iron ayidingi ukutholwa ngezando nezinye izinto. Umphumela uyinqubo encane yokucwengezayo kanye nomkhiqizo wokugcina oshibhile.
Insimbi eyenziwe nge-galvanized yenziwa ngensimbi yekhabhoni ehlanganiswe ne-zinc under evikelayo. Lokhu kwenziwa ngenqubo ebizwa nge-galvanization yazo kunezinhlobo eziningana ezahlukahlukene, njengokufafaza okushisayo, ukushisa okushisayo, i-electroplating, nokuningi. Ekushisweni okushisayo kwe-galvanization, i-carbon yensimbi icwilisa ku-zinc eshisayo ethambile ngamazinga okushisa aze afike ku-460 ° C. Ngemuva kokuba ihlanganiswe ngokuphelele, iphakanyiswa isipele futhi ivezwe emkhathini. Lokhu kuvezwa kuzokwenza i-zinc yasabela ku-oksijini, yakha i-zinc onide. Ngaphezu kwalokho, bese uphendula ngekhabhoni ekhona emoyeni ukuze akha i-zinc carbonate, eyakha ungqimba olumpunga ebusweni bensimbi. Noma ihlanganiswe kwenye into, i-Steel Ihlala ihlala ingenamkhawulo futhi isetshenziswe kalula eminye imishini yokukhiqiza insimbi.
Inkani
I-Cast Iron ngokuvamile imelana nokugqwala komkhathi. Banokumelana okuphezulu kunamanye ama-alloys ensimbi. I-Iron Iron nayo igqoke futhi ingavimba ukunyakaza. Kodwa-ke, i-cast irons ithambekele kakhulu emanzini olwandle futhi ihlushwa kalula futhi ifakwe lapho ifakwa ngaphansi kokuvezwa isikhathi eside ezindaweni ezinosawoti. I-cast iron nayo ingaba ngaphezudlwana kwezinye izinsimbi ezisetshenzisiwe.
Insimbi ye-Galvanized imelana kakhulu nokuphikisana kakhulu uma kuqhathaniswa nezinye izinsimbi eziningi. Inezindlela ezimbili zokuncishiswa kokugqwala, okuvela kwinqubo ye-galvanization. I-zinten i-zinc ibopha ingaphezulu lensimbi yekhabhoni njengezinhlungu, futhi yakha isendlalelo esihle kakhulu se-oxide. Inikeza ne-anode ye-zinc ukuthola ukubhucuka esikhundleni sensimbi.
Uma ngabe i-zinc coating ilinyazwe noma iklanywe, i-zinc anode isengavikela insimbi ezungezile. I-zinc esele esele nayo ingaphinda inikeze ukuhlanganiswa kwayo okuvikelayo kwe-zinc onide. Ifana ne-aluminium, i-zinc isebenza kakhulu ku-oksijini futhi ngenxa yalokho idonsa kakhulu umoya-mpilo ohlangana nawo. Lokhu kuvimbela insimbi ngaphansi kokugoqwa kusuka ku-oxidation ezinye.
Sebenzisa
I-Cast Iron iyinto eqinile futhi emelana nensimbi emelana ne-metal, okwenza ilungele izinhloso ezahlukahlukene. I-Iron ye-Cast ingasetshenziswa ukwenza amagiya ezimoto, izakhi namapayipi wezimoto. Ingasetjenziswa ekutholeni insimbi yokufa kwensimbi kanye nezingxenye zemishini zokukhiqiza. I-Cast Iron nayo itholakala kakhulu ekhishini njengoba ilungele izinhloso zokushisa, kanye nendlela evame kakhulu yemishini yokupheka ye-Iron Coom ithonya amapani. Kodwa-ke, ungathola futhi izitsha zensimbi, isikhunta sokubhaka, nokupheka amapani. Baphinde batholwe ku-Plumbing, yize kungenzeki kabanzi futhi ngokuvamile abanconyelwanga amakhaya amasha.
Insimbi ye-galvanized ithandeka ukusetshenziswa kwayo okuhlala isikhathi eside kanye nezakhiwo ezingamelana nazo. Isibonelo esisodwa sokusetshenziswa kwaso singamapayipi anamapayipi. Ungqimba lwayo oluvikelayo lwe-zinc luvikela kalula ekugqwabeni - uhlobo lokugqwala. Insimbi ye-Galvanized nayo isetshenziswa kumafreyimu wensimbi ekwakhiweni kwendlu. Ingasetshenziswa futhi ukwenza izitho zomzimba nezimoto eziningi zemoto kanye namakheji. Le nsimbi nayo ingatholakala kumagiya egiya lokuvikela kanye nezimpawu zomgwaqo omkhulu endleleni.
Izinzuzo
Zombili lezi zinsimbi zinezindawo ezinde kakhulu eziqhathaniswa nezinye izinhlobo zensimbi, ezinomthelela ekubukeni kwazo futhi zigqoke ukumelana. Inzuzo ye-Iron Iron ngaphezulu kwamanga ensimbi emandleni ayo okugcina ukushisa isikhathi eside kunezinhlobo eziningi zensimbi. Lokhu kwenza ukuthi ilungele izinhlelo zokusebenza ezidinga amazinga okushisa aqinile futhi angaguquki, njengokupheka. Kodwa-ke, njengoba kungukumelana nokugqwala okuncane nokulimala, kungafanelekile ukuthi izinhlelo zokusebenza ezikuveze ku-ketshezi kanye nengcindezi ephezulu, njengokuphambanisa amapayipi.
I-Steel ye-Galvanized inazo zonke izinzuzo ongazitholela ngensimbi, kanye nokuphikiswa okuthuthukile ezindaweni eziningi. Insimbi eyenziwe nge-galvanized nayo ingenakuqhathaniswa ne-iron yensimbi, okusho ukuthi amapayipi ensimbi egayiwe kanye namashubhu akhiqizwa kalula futhi ahlelwe ngokwengeziwe ngezinhloso zawo ezihlosiwe. Insimbi ye-Galvanized inenzuzo eyengeziwe yokumelana nezikhathi ezimanzi nezikhathi ezomile, ezizogqwala ezinye izinsimbi eziningi. Lokhu kwenza kube kuphelele ukwenza izingxenye zamapayipi.
