Siyinqanda njani irusi kwindawo eyandisiweyo yokugada umnatha wentsimbi zezi zilandelayo:
1. Guqula isakhiwo sangaphakathi sesinyithi
Umzekelo, ukwenza iialloyi ezahlukeneyo ezikwaziyo ukutyiwa, ezinjengokufaka ichromium, nickel, njl.njl. kwintsimbi eqhelekileyo ukwenza intsimbi engatyiwa.
2. Indlela yokukhusela
Ukugquma umphezulu wesinyithi kunye nomaleko okhuselayo ukwahlula imveliso yentsimbi kwindawo erhangqeyo ukuthintela ukubola.
(1). Gcoba umphezulu womnatha wentsimbi owandisiweyo nge-oyile ye-injini, i-petroleum jelly, uyipeyinte okanye uyigqume ngezinto ezikwaziyo ukumelana nentsimbi ezifana ne-enamel neplastiki.
(2). Sebenzisa i-electroplating, i-hot plating, i-spray plating kunye nezinye iindlela zokugquma umphezulu wepleyiti yentsimbi kunye nomaleko wesinyithi ongekho lula, njenge-zinc, i-tin, i-chromium, i-nickel, njl. Ezi zinyithi zihlala zenza ifilimu ye-oxide eshinyeneyo ngenxa ye-oxidation, ngaloo ndlela ikhusela amanzi kunye nomoya kwintsimbi ebolileyo.
(3). Sebenzisa iindlela zeekhemikhali ukwenza ifilimu ecocekileyo kunye nezinzileyo ye-oxide kwindawo yentsimbi. Ngokomzekelo, ifilimu ecocekileyo ye-ferric oxide yenziwa kumphezulu weplate yensimbi.
3. Indlela yokukhusela i-Electrochemical
Indlela yokukhusela i-electrochemical isebenzisa umgaqo weeseli ze-galvanic ukukhusela isinyithi kwaye izama ukuphelisa ukuphendula kweeseli ze-galvanic ezibangela ukubola kwe-galvanic. Iindlela zokukhusela i-electrochemical zihlukaniswe ngamacandelo amabini: ukukhuselwa kwe-anode kunye nokukhuselwa kwe-cathodic. Eyona ndlela isetyenziswa kakhulu kukukhusela i-cathodic.
4. Phatha imidiya eyonakalisayo
Ukuphelisa imidiya ephazamisayo, efana nokusula rhoqo izixhobo zetsimbi, ukubeka i-desiccants kwizixhobo ezichanekileyo, kunye nokongeza inani elincinci le-corrosion inhibitors elinokuthi licothise izinga le-corrosion kwi-corrosion media.
5. Ukukhuselwa kwe-Electrochemical
1. Indlela yokukhusela i-anode yombingelelo: Le ndlela idibanisa isinyithi esisebenzayo (njenge-zinc okanye i-zinc alloy) kwintsimbi ukuze ikhuselwe. Xa i-galvanic corrosion isenzeka, le ntsimbi esebenzayo isebenza njenge-electrode engalunganga ukuze ingene kwi-oxidation reaction, ngaloo ndlela inciphisa okanye ithintele i-Corrosion yentsimbi ekhuselweyo. Le ndlela isoloko isetyenziselwa ukukhusela iimfumba zentsimbi kunye neegobolondo zeenqanawa ezihamba elwandle emanzini, ezifana nokukhuselwa kwamasango ensimbi emanzini. Iziqwenga ezininzi ze-zinc zidla ngokudityaniswa ngaphantsi komgca wamanzi weqokobhe lenqanawe okanye kwiphini lokujika elikufutshane nepropeller ukuthintela i-hull, njl.njl. ukuhlwa.
2. Indlela yokukhusela yangoku echukumisekileyo: Xhuma isinyithi ukuze ukhuselwe kwisibonda esibi sonikezelo lwamandla, kwaye ukhethe esinye isiqwenga se-condutive inert material ukudibanisa kwisibonda esilungileyo sonikezelo lwamandla. Emva kokunika amandla, ukuqokelelwa kweentlawulo ezimbi (i-electron) kwenzeka kumphezulu wesinyithi, ngaloo ndlela kuthintela isinyithi ekulahlekeni kwee-electron kunye nokufezekisa injongo yokukhusela. Le ndlela isetyenziselwa ukuthintela ukubola kwezixhobo zetsimbi emhlabeni, emanzini olwandle kunye namanzi omlambo. Enye indlela yokukhusela i-electrochemical ibizwa ngokuba yi-anode yokukhusela, okuyinkqubo apho i-anode idluliswa phakathi koluhlu oluthile olunokwenzeka ngokusebenzisa i-voltage yangaphandle. Inokuthi ivimbele ngokufanelekileyo okanye ithintele izixhobo zetsimbi kwi-corroding kwi-acids, i-alkali kunye neetyuwa.
