Injongo ephambili ye uvavanyo lokutshiza ngetyuwa kunye nokumelana namanzi amdakaIpayipi ye-SMLIingubo ezikwi-EN877 kukuvavanya ukumelana kwexesha elide kwengubo kwi-chemical corrosion (ii-asidi, ii-alkalis, iityuwa), i-electrochemical corrosion, kunye ne-microbial corrosion ngokulinganisa iindawo ezirhabaxa nezirhabaxa zehlabathi lokwenyani (i-salinity ephezulu kunye namanzi amdaka antsonkothileyo eekhemikhali/ebhayoloji).Olu vavanyo luqinisekisa amandla okufakwa kwesinyithi ekukhuseleni ngempumelelo isiseko sesinyithi ekungcoleni kulo lonke ixesha loyilo lombhobho. Oku kuqinisekisa ukuba ukufakwa kwesinyithi kugcina ukuthembeka okufanelekileyo kunye nokunamathela emva kwenkonzo ende.
Ivavanya ngokungathanga ngqo amandla okugcina udonga lwangaphakathi lombhobho lugudileyo kwaye iqinisekise ukuba amanzi ahamba kakuhle. Olu vavanyo lusebenza njengesiseko esiphambili solawulo lomgangatho wemveliso kunye nokufumana isiqinisekiso esisemgangathweni.
Ukuchasana ne-spray yetyuwa
Uvavanyo kufuneka lwenziwe ngokuhambelana ne-EN IS0 9227 kwaye emva kwexesha lovavanyo elingaphantsi kweeyure ezingama-350, iisampulu mazihlanjwe ngamanzi angenazimbiwa ukuze kususwe iintsalela zetyuwa. Iingubo kufuneka zihlolwe ngoko nangoko ukuba azinazo na iimfene okanye zirhawuzelelwe.
Inkqubo yoVavanyo:Uvavanyo lwe-salt spray lusebenzisa i-neutral salt spray ye-Isisombululo se-NaCl se-5% iiyure ezingama-350Emva kokuba ixesha lovavanyo ligqityiwe, hlambulula ngamanzi angenatyuwa ukuze ususe ityuwa eseleyo, kwaye ngoko nangokohlola uqweqwe lwangaphakathi ukuba alunamhlwa na kwaye alunamingxumaInqanaba lemingxuma yepin ayidluli kwiKlasi yesi-3, njengoko kuchaziwe kwi-ISO 4628-2, kwaye inqanaba lomhlwa alidluli kwiKlasi yesi-2, njengoko kuchaziwe kwi-ISO 4628-3.
Isidanga semingxunya yesanti: Ibanga lesi-3 okanye ngaphezulu njengoko kuchaziwe kwi-ISO4628-2; Isidanga somhlwa: Ibanga lesi-2 okanye ngaphezulu njengoko kuchaziwe kwi-ISO4628-3
Ukuxhathisa amanzi amdaka
Iisampulu mazintywiliswe emanzini ukuze30d emanzini amdaka kubushushu obuyi (23 + 3)°Ckunye nokwakheka okunikiweyo kwiTheyibhile 8.
Inkqubo yoVavanyo:Ekupheleni kwexesha lokuntywiliselwa emanzini, iisampulu mazihlanjwe ngamanzi angenazimbiwa zize zomiswe. Ziya kuhlolwa ngoko nangoko ukuba azinazo na iimfene okanye umonakalo.Iiyure ezingama-24 kubushushu obuphakathi be (23±3)°Ciisampulu ziya kuhlolwa kwakhona.
Akuyi kwamkelwa ukulahleka kokunamathela kunye nokugqwala.
