Izici ze-Zinc Alloys

Izakhiwo Eziyinhloko:

Ukuminyana okuphezulu.

Izakhiwo ezinhle zokubumba; ikwazi ukukhiqiza izingxenye eziyinkimbinkimbi, ezinodonga oluncane ezinezindawo ezibushelelezi.

Ifanele ukwelashwa kwendawo: ukufakelwa nge-electroplating, upende oluyimpuphu, kanye nokupenda.

Ayidonsi insimbi ngesikhathi sokuncibilika nokuphonswa ngodayi, ayigqwali idayisi, futhi ayinamatheli esikhumbeni.

Izakhiwo ezinhle kakhulu zemishini kanye nokumelana nokuguguleka ekamelweni lokushisa.

Indawo yokuncibilika ephansi (385°C), okwenza kube lula ukuyicwilisa.

Amaphuzu Okufanele Uwaqaphele Ngesikhathi Sokusebenzisa:

Ukumelana Okubi Kokugqwala

Uma izinto ezingcolile ezifana ne-lead, i-cadmium, ne-tin zidlula imikhawulo ejwayelekile ekwakhiweni kwe-alloy, kubangela ukuthi ukuthungwa kuguge futhi kuguquke, okubonakala njengokwanda kwevolumu kanye nokwehla okukhulu kwezakhiwo zemishini—ikakhulukazi i-plasticity—futhi kungaholela nasekuqhekekeni ngokuhamba kwesikhathi. I-lead, i-tin, ne-cadmium zinokuncibilika okuphansi kakhulu kuma-alloy e-zinc ngakho-ke kugxila emingceleni yokusanhlamvu, kusebenza njengama-cathode, kuyilapho isixazululo esiqinile esicebile nge-aluminium sisebenza njenge-anode. Lapho kukhona umhwamuko wamanzi (i-electrolyte), lokhu kukhuthaza ukugqwala kwe-electrochemical intergranular. Izingxenye ezithungwe nge-die ziyaguga ngenxa yokugqwala kwe-intergranular.

Imiphumela Yokuguga

Isakhiwo esincane sama-alloy e-zinc siqukethe ngokuyinhloko izixazululo eziqinile ezicebile nge-zinc eziqukethe i-Al ne-Cu, kanye nezixazululo eziqinile ezicebile nge-Al eziqukethe i-Zn. Ukuncibilika kwazo kwehla njengoba izinga lokushisa lehla. Kodwa-ke, ngenxa yesilinganiso sokuqina esisheshayo sezingxenye ezifakwe ngokufa, ukuncibilika kwalezi zixazululo eziqinile kugcwala kakhulu ngesikhathi ingxenye ifinyelela izinga lokushisa legumbi. Ngemva kwesikhathi esithile, lokhu kugcwala kuyanyamalala kancane kancane, okubangela izinguquko ezincane esimweni kanye nobukhulu bokugcwala.

Imikhawulo Yokushisa

Ama-die-castings e-zinc alloy akufanele asetshenziswe ezindaweni zokusebenza ezinokushisa okuphezulu noma okuphansi (ngaphansi kuka-0°C). Ama-zinc alloy abonisa izakhiwo ezinhle zomshini ekushiseni kwegumbi. Kodwa-ke, amandla okudonsa ancipha kakhulu emazingeni okushisa aphezulu, futhi amandla okushaya ancipha kakhulu emazingeni okushisa aphansi.

Izinhlobo ze-Zinc Alloys

Uhlobo lwe-alloy	Izici kanye nezicelo
I-Zamak 3	Ukugeleza okuhle kanye nezakhiwo zemishini. Isetshenziselwa ukuthunga okunezidingo eziphansi zamandla emishini, njengamathoyizi, izibani, izinto zokuhlobisa, kanye nezingxenye ezithile zikagesi.
I-Zamak 5	Ukugeleza okuhle kanye nezakhiwo ezinhle kakhulu zemishini. Isetshenziselwa ukuthunga ngezidingo zamandla omshini ezimaphakathi, njengezingxenye zezimoto, izingxenye ze-electromechanical, izingxenye zemishini, kanye nezingxenye zikagesi.
I-Zamak 2	Isetshenziselwa izingxenye zemishini ezinezidingo ezikhethekile zokusebenza kwemishini, izidingo zobulukhuni obuphezulu, kanye nezidingo zokunemba okujwayelekile.
I-ZA8	Ukugeleza okuhle kanye nokuzinza kobukhulu, kodwa ukugeleza okuncane. Kusetshenziselwa ukusika izinto zokusebenza ezincane ezinobukhulu obuphezulu kanye nezidingo zamandla omshini, njengezingxenye zikagesi.
I-Superloy	Ukugeleza okuhle kakhulu, okusetshenziselwa ukusika izinto zokusebenza ezinezindonga ezincane, ezinkulu, ezinembe kakhulu, nezinomumo oyinkimbinkimbi, njengezingxenye zikagesi kanye nezindawo zazo zokuvala.

Ama-alloy e-zinc ahlukene anezakhiwo ezihlukile zomzimba nezemishini, okunikeza ukuguquguquka ekwakhiweni kwezingxenye ezifakwe insimbi.

Ukukhethwa kwama-Zinc Alloys

Ukukhethwa kwe-zinc alloy kunqunywa kakhulu yizici ezintathu:

Ukusetshenziswa okuhlosiwe kwengxenye ehlanganisiwe kanye nemininingwane yokusebenza edingekayo.

(1) Izakhiwo Zemishini

Amandla okuthamba, okuwukumelana okuphezulu kwezinto ngaphambi kokuqhekeka; ukunwebeka, okulinganisa ibhalansi phakathi kokuqhekeka kanye nokuqina; kanye nobunzima, okuwukumelana kobuso bezinto nezinto ekuguqukeni kwepulasitiki okubangelwa ukugoba noma ukungqubuzana okuvela entweni eqinile.

(2) Izimo Zendawo Yokusebenza

Izinga lokushisa lokusebenza, umswakama, imidiya lapho umsebenzi uhlangana khona, kanye nezidingo zokungabi nomoya.

(3) Izidingo Zokunemba

Ukunemba okufinyelelekayo kanye nokuzinza okulinganiselwe.

Ukucutshungulwa Okuhle

(1) Inqubo yokukhipha

(2) Ukusebenziseka kalula

(3) Ukucutshungulwa kokwelashwa kwendawo

Ukuphila Okuhle Kwezomnotho

Izindleko zezinto ezingavuthiwe kanye nezidingo zemishini yokukhiqiza (kufaka phakathi imishini yokuncibilikisa, imishini yokukhipha udayi, isikhunta, njll.), kanye nezindleko zokukhiqiza.

Ukulawulwa Kokwakheka Kwe-Zinc Alloy
