Unyango oluqhelekileyo lomphezulu kwiiBolts

Ukwaleka: ukufaka isambatho kumphezulu webholi ukwenza ifilim efanayo ephucula ukuxhathisa ukubola kunye nenkangeleko.. Inzuzo kukuba ibonakala ilungile, kodwa into engalunganga kukuba ayihlali kwaye ikrweleka ngokulula.
I-Hot-dip galvanizing: ukuntywilisela ibholithi kwi-zinc etyhidiweyo ukuphucula ukuxhathisa kwayo ekudlekeni. I-advanteji yeyokuba inamandla okuthintela ukubola kwaye akukho lula ukuwa, kodwa into embi kukuba umphezulu awumhle ngokwaneleyo.
Electroplating: ukuntywiliselwa ibholithi kwi-electrolyte kunye nokubeka umaleko wesinyithi kumphezulu webholithi nge-electrolysis ukuphucula ukuxhathisa ukubola kunye nenkangeleko.. Inzuzo kukuba umphezulu ugudile kwaye umhle, kodwa into engeloncedo kukuba ithande ukuba ne-hydrogen embrittlement.
Dacro: ukuntywilisela iibholiti kwisisombululo se-zinc-aluminiyam, ukuqinisekisa ukuba i-bolt idibene ngokupheleleyo nesisombululo ngaphambi kokugungqa isisombululo esingaphezulu kunye nokusomisa. Phinda le nkqubo ingentla 2-4 amaxesha ukwenza ifilimu eshinyeneyo kumphezulu webholithi, ukufezekisa umphumo we-anticorrosion. Inzuzo yale nkqubo kukuba umphezulu mhle kwaye akulula ukuwa, kodwa into engalunganga kukuba ayihlali kwaye ikrweleka ngokulula. Ngoku kukho i-hexavalent chromium-free formula, ehambelana nokusingqongileyo.
