Ijolise kakhulu kwimibhobho yensimbi, ejongene nokuphendula kwe-corrosion, kwaye kukho ingozi ethile efihliweyo kumonakalo wezixhobo emva kokubola.Emva kokususa zonke iintlobo zeoli, i-rust, isikali, amabala e-welding kunye nolunye ukungcola, kunokuphucula kakhulu ukuxhathisa ukubola kwentsimbi.

Ukuba kukho ukungcola phezu komhlabaumbhobho wensimbi engenasici, kufuneka icocwe ngoomatshini ize ke icocwe.Ubukho begrisi phezu komhlaba buya kuchaphazela umgangatho wokukhetha kunye nokugqithisa.Ngenxa yesi sizathu, ukukhutshwa kwegrisi akunakushiywa.Ungasebenzisa i-lye, i-emulsifiers, i-solvents eziphilayo kunye nomphunga.

I-Passivation yinkqubo yokugqibela yokucocwa kweekhemikhali kwaye linyathelo eliphambili.Injongo yalo kukuthintela ukubola kwezinto.Ngokomzekelo, emva kokuba ibhoyila ivutshiwe, ihlanjwe ngamanzi, kwaye ihlanjululwe, indawo yesinyithi icocekile kakhulu, isebenze kakhulu, kwaye ixhomekeke kwi-corrosion, ngoko ke kufuneka igqitywe ngokukhawuleza ukwenza ifilimu ekhuselayo kwindawo yentsimbi ecociweyo ukunciphisa. umhlwa.
