Intshayelelo
Inkqubo yokwenziwa kwamashiti entsimbi yintsika kwishishini lentsimbi, ebonelela ngezinto eziyimfuneko kwizicelo ezininzi ukusuka kulwakhiwo ukuya kwimveliso yeemoto. Kwiifektri, abasasazi, kunye nabathengisi bevenkile, ukuqonda ukuntsonkotha kwale nkqubo kubalulekile ekuqinisekiseni umgangatho wemveliso kunye nokuhlangabezana neemfuno zeshishini. Olu hlalutyo lubanzi lujonge kwiindlela, izixhobo, kunye neetekhnoloji ezibandakanyekayo ekuveliseni umgangatho ophezulu. Amashiti esinyithi enziwe ngesinyithi , akhanyisa ukubaluleka kwawo kumhlaba wanamhlanje wezoshishino.
Iziseko zeGalavanization
I-galvanization yinkqubo ye-metallurgical ebandakanya ukugquma intsimbi okanye isinyithi kunye nomgca we-zinc ukukhusela ukubola kunye nokuhlwa. I-zinc layer isebenza njengesithintelo sokukhusela, ukukhusela isiseko sesinyithi kwizinto ezisingqongileyo ezifana nokufuma kunye ne-oksijini. Le nkqubo yandisa ixesha lokuphila kweemveliso zetsimbi kunye nokwandisa ukuqina kwazo, okwenza amashiti ensimbi enziwe ngentsimbi ibe yinto ekhethiweyo kumashishini ahlukeneyo.
Isishwankathelo sezeMbali
Ingcamango ye-galvanization ibuyele ekuqaleni kwekhulu le-19 xa uLuigi Galvani wafumanisa inkqubo ye-electrochemical ebizwa ngokuba yigama lakhe. Noko ke, akuzange kube ngowe-1830 apho kwavela khona izicelo zokuqala zokwenziwa kwegalvanization. Inkqubo iye yavela kakhulu ukususela ngoko, ibandakanya itekhnoloji ephezulu kunye neendlela zokuphucula ukusebenza kakuhle kunye nomgangatho wemveliso.
IMathiriyeli ekrwada kunye neeNkqubo zoNyango lwangaphambili
Ukuveliswa kweeshiti zetsimbi zentsimbi kuqala ngokukhetha izinto ezisemgangathweni ophezulu. Amacandelo aphambili ngamashiti ensimbi kunye ne-zinc, kunye nokucoceka kunye nokwakhiwa kwazo zombini iindima ezibalulekileyo ekusebenzeni kwemveliso yokugqibela.
Ukhetho Lwentsimbi
Ukukhetha ibakala elifanelekileyo lentsimbi kubalulekile ukuze kuphunyezwe iziphumo ezigqwesileyo zokugalela. Izinto ezifana nomxholo wekhabhoni, umgangatho womphezulu, kunye neempawu zomatshini kufuneka ziqwalaselwe. Intsimbi ephantsi kwekhabhoni isetyenziswa ngokuqhelekileyo ngenxa yobuchule bayo bokubumba obugqwesileyo kunye nokuhambelana nenkqubo yokugquma i-zinc.
Ukulungiswa komphezulu
Ngaphambi kokufakwa kwe-galvanization, amashiti entsimbi acocwa ngokungqongqo ukuze asuse izinto ezingcolisayo njengeoyile, ukungcola, kunye nesikali sokusila. Inkqubo yonyango lwangaphambili ibandakanya ukuthambisa, ukuchola kwizisombululo zeasidi, kunye nokuguquguquka. Oku kuqinisekisa ukuba umphezulu wentsimbi ucocekile ngokwekhemikhali, ukhuthaza ukunamathela okuqinileyo phakathi kwengubo ye-zinc kunye ne-substrate yensimbi.
Iindlela zokugalela
Kukho iindlela ezimbini eziphambili zokutshiza amashiti ensimbi: i-hot-dip galvanizing kunye ne-electrogalvanizing. Indlela nganye ibonelela ngeenzuzo ezahlukeneyo kwaye ifanelekile kwizicelo ezithile.
Hot-Dip Galvanizing
Ukuntywiliselwa kwidiphu eshushu kubandakanya ukuntywiliselwa kwamaphepha entsimbi alungisiweyo kwibhafu enezinki enyibilikisiweyo efudunyezwe malunga nama-450°C(842°F). Intsimbi iphendula kunye ne-zinc, yenza uluhlu lwezinki-intsimbi ye-alloy layers egqitywe ngoluhlu lwe-zinc ecocekileyo. Le ndlela iyasebenza kakhulu ekuboneleleni ukuxhathisa okuqinileyo kwaye isetyenziswa kakhulu ngenxa yeendleko zayo kunye neengubo ezityebileyo eziyivelisayo.
Ngokutsho kwe-American Galvanizers Association, i-hot-dip galvanizing inokufikelela kubukhulu be-coating ukusuka kwi-45 ukuya kwi-85 microns, kuxhomekeke kwizinto ezifana nexesha lokuntywiliselwa kunye nokwakhiwa kwentsimbi. Amaphepha enziwe ngesinyithi aphekiweyo afanelekile kwiindawo ezinzima apho kufuneka ukhuseleko oluphezulu.
Electrogalvanizing
I-Electrogalvanizing, okanye i-electroplating, ibeka i-zinc yokugqoka kwi-steel surface isebenzisa umbane okhoyo kwisisombululo se-electrolytic. Le ndlela ivumela ulawulo oluchanekileyo phezu kobunzima bokugquma, ngokuqhelekileyo ukuvelisa iileyile ezincinci ukusuka kwi-5 ukuya kwi-30 microns.
