Kubunjineli obusebenzayo, kukho iindlela ezintathu eziphambili zokukhusela i-corrosion yensimbi.
1.Indlela yefilimu ekhuselayo
Ifilimu ekhuselayo isetyenziselwa ukuhlukanisa intsimbi ukusuka kwindawo ejikelezileyo, ukuphepha okanye ukunciphisa umphumo owonakalisayo we-corrosive medium kwintsimbi.Umzekelo, ukutshiza ipeyinti, i-enamel, iplastiki, njl njl kumphezulu wensimbi;okanye usebenzise iingubo zentsimbi njengefilimu ekhuselayo, njenge-zinc, i-tin, i-chromium, njl.
2.Indlela yokukhusela i-electrochemical
Isizathu esithile sokubola singahlulwa sibe yindlela yokukhusela engekhoyo kunye nendlela yokukhusela yangoku.
Indlela yokukhusela engekho yangoku ikwabizwa ngokuba yindlela ye-anode yedini.Kukudibanisa isinyithi esisebenza ngakumbi kunentsimbi, njenge-zinc kunye ne-magnesium, kwisakhiwo sensimbi.Ngenxa yokuba i-zinc kunye ne-magnesium inamandla angaphantsi kunentsimbi, i-zinc, kunye ne-magnesium iba yi-anode yebhetri yokubola.yonakele (i-anode yombingelelo), ngelixa isakhiwo sensimbi sikhuselekile.Le ndlela isoloko isetyenziselwa iindawo apho kungekho lula okanye kungenzekiyo ukugquma umaleko okhuselayo, njengezibiyeli zomphunga, imibhobho engaphantsi komhlaba yamaqokobhe enqanawa, izakhiwo zobunjineli bezibuko, izakhiwo zendlela kunye neebhulorho, njl.
Indlela yokhuseleko yangoku esetyenziswayo kukubeka ezinye iintsimbi ezilahliweyo okanye ezinye iintsimbi eziphikisayo kufutshane nesakhiwo sentsimbi, njengentsimbi ye-silicon ephezulu kunye ne-lead-silver, kunye nokudibanisa ipali engalunganga yonikezelo lwamandla lwe-DC lwangaphandle kwisakhiwo sentsimbi ekhuselweyo, kunye isibonda esihle sidityaniswe nesakhiwo sesinyithi esichasayo.Kwisinyithi, emva kokufakelwa kombane, isinyithi esichasayo siba yi-anode kwaye i-corrod, kwaye isakhiwo sensimbi siba yi-cathode kwaye ikhuselwe.
3.Taijin Chemical
Intsimbi yeCarbon yongezwa kunye nezinto ezinokuphucula ukuxhathisa ukubola, njenge-nickel, i-chromium, i-titanium, ithusi, njl., ukwenza iintsimbi ezahlukeneyo.
Ezi ndlela zingasentla zingasetyenziselwa ukuthintela ukubola kweentsimbi zentsimbi kwikhonkrithi eyomeleziweyo, kodwa eyona ndlela yoqoqosho kunye neyona ndlela isebenzayo kukuphucula ukuxinana kunye ne-alkalinity yekhonkrithi kunye nokuqinisekisa ukuba imivalo yentsimbi inomlinganiselo owaneleyo wokukhusela.
Kwimveliso ye-cement hydration, ngenxa ye-calcium hydroxide malunga ne-1/5, ixabiso le-pH lephakathi li malunga ne-13, kwaye ubukho be-calcium hydroxide bubangela ukuba ifilimu ye-passivation ebusweni bentsimbi yentsimbi ukwenza umaleko wokukhusela.Ngelo xesha, i-calcium hydroxide inokuthi isebenze kunye newotshi ye-atmospheric CQ ukunciphisa i-alkalinity yekhonkrithi, ifilimu ye-passivation inokutshatyalaliswa, kwaye umphezulu wensimbi ukwimo esebenzayo.Kwindawo enomswakama, i-electrochemical corrosion iqala ukwenzeka kumphezulu wentsimbi yentsimbi, okubangela ukuqhekeka kwekhonkrithi ecaleni kwebar.Ngoko ke, ukuchasana kwe-carbonization yekhonkrithi kufuneka kuphuculwe ngokuphucula ukudibanisa kwekhonkrithi.
Ukongeza, i-chloride ion inefuthe lokutshabalalisa ifilimu ye-passivation.Ngoko ke, xa ulungiselela ikhonkrithi eqinisiweyo, inani letyuwa yekloridi kufuneka lilinganiselwe.
