Intshayelelo
Kwimeko yemizi-mveliso yanamhlanje, imfuno yezinto ezidibanisa ukuqina kunye nokusebenza kakuhle kweendleko azizange zibe phezulu. Intsimbi, icandelo elisisiseko kulwakhiwo kunye nemveliso, ifuna ukhuseleko oluluqilima kumhlwa ukuze kuqinisekiswe ubomi obude kunye nentembeko yesakhiwo. Phakathi kweendlela ezahlukeneyo ezikhoyo, I-Hot Dipped Steel Coil iye yavela njengokhetho oluphezulu lweefektri, abathengisi betshaneli, kunye nabasasazi. Eli nqaku lijonga kwiingenelo eziphambili zokusebenzisa ikhoyili yentsimbi etshisiweyo etshisiweyo, iphonononga iingenelo zayo, usetyenziso, kunye nenzululwazi emva kokusebenza kwayo.
Inkqubo yeHot Dip Galvanization
Ukuxabisa ngokupheleleyo iingenelo zekhoyili yentsimbi editshiweyo eshushu, kubalulekile ukuqonda inkqubo yokwenziwa kwegalvanization ngokwayo. Ukuntywiliselwa kwentsimbi eshushu kubandakanya ukuntywiliselwa kwentsimbi kwibhafu enezinki enyibilikisiweyo efudunyezwe malunga nama-450°C (842°F). Le nkqubo ibangela ibhondi ye-metallurgical phakathi kwe-zinc kunye nentsimbi, eyenza uluhlu lwezinki-iron alloy layers. Umgangatho ongaphandle yi-zinc ecocekileyo, enika isiphelo esiqinileyo nesikhuselayo esixhathisa ukubola.
Isigaba sokulungiselela sibalulekile, sibandakanya ukucoca intsimbi ukususa konke ukungcola. Oku kuqinisekisa ukunamathela ngokufanelekileyo kwengubo ye-zinc. Intsimbi ihlanjululwa kuqala ukuphelisa ioyile kunye nokungcola, kulandele ukukha kwisisombululo esineasidi ukususa umhlwa kunye nesikali sokugaya. Isisombululo se-flux ke sisetyenziselwa ukuthintela i-oxidation ngaphambi kokuntywiliselwa kwi-zinc etyhidiweyo. Isiphumo yintsimbi yentsimbi ehlanganiswe ngokufanayo kunye neempawu zokukhusela eziphuculweyo.
IziNzuzo eziPhambili zokuSebenzisa iKhoyili yentsimbi eDitshweyo eDitshweyo
Ukuqina kwexesha elide
Enye yeenzuzo ezibalulekileyo kukuqina okukhethekileyo okubonelelwa yi-zinc coating.
