Ts'enyeho Tšireletso

lihlahisoa Metal ka mor'a nako butle-butle koahetsoeng ka patina Rusty. Kaho timetsoa hoo e ka bang fetoha lerōle. Ho qoba diphetho joalo malimabe, o lokela ho tseba seo ha e ts'enyeho ea tšepe le kamoo ho ka sireletsa khahlanong le eona. Metal e tlas'a tlontlollong ka lebaka la ho pepesehela tikoloho ka ntle, e leng electrochemically kapa lik'hemik'hale. Lik'hemik'hale ts'enyeho bonahala mecheng ea litaba ha li khona ho khanna e morao-rao ea motlakase (oli, khase, alcohols). O ile a pepesa ho feletseng tsohle tšepe. Motlakase ya ts'enyeho le hlaha ka lebaka la ho ketsahalo ea filimi electrolytic tšepe e loketseng ho litšusumetso tikoloho. Ka ho khetheha, sephetho-botekgeniki ntlo ea letsoai sebelisoa ka litsela tse mariha, 'me maqhubu a itaola. Litsela Tsa le mekhoa eo ho eona e entseng ho tloha ts'enyeho, ho na le tse ngata.

Ka ho fetisisa ratoa le atile ho sebelisa coatings. Ba tla ka tšepe le matsoai bao e seng metallic. Greater bohlokwa ba tsamaiso fana coatings thehiloeng bōpa leshano polymers maiketsetso. Inorganic bao e seng metallic barbotage e sa tšoaneng haholo. Tsena li akarelletsa pente (oli, alkyd le enamel) le lipolisheng (lehong sekontiri, a maiketsetso a sekontiri se thata). Ha o etsa kopo joalo tšireletso ts'enyeho baka e tšesaane filimi ea kenyelletsa tšepe ho tloha mongobo le phello e tikoloho. Pente le lipolisheng ke ho bonolo ho e sebelisa, ka theko e tlaase. Qalong ea mosebetsi oa e ho hlokahala hore ho ka tieo latela theknoloji ea kopo tsa bona. Sekoahelo sa holim'a tšepe hlokahala ka le dikarolo a 'maloa ho molemo sireletsa dibopeho tšusumetsong sepakapakeng.

Metallic coatings inhibitors khetholla mefuta e 'meli. Pele sehlabelo barbotage kenyeletsa cadmium, zinki, aluminium. Ea bobeli - ts'enyeho manganga barbotage tsa koporo, silevera, loto, nikele le chromium.

Ho itšetlehile ka hore na mochine ketso e ts'enyeho tšireletso, e bitsoa e cathode kapa anode. Ho na le tšepe coatings, inhibitors le electronegativity moholo, 'me coatings ho ba le electropositive phahameng. Anode coatings e matleng a hae ho mofuta pele, cathode - ho ea bobeli ea. Tshebediso ya aluminium le zinki, e le cathode ka anode coatings - nikele, koporo, thini.

mekhoa e sa tšoaneng ea ho sireletsa tšepe khahlanong ts'enyeho le akarelletsa embodiments maloa barbotage. Ka mohlala, bakeng sa tshebediso ya inhibitors lik'hemik'hale e sebediswa mokhoa bakeng sa ho bitiela metallic dibopeho lirafshoa tse ling: aluminium, zinki.

Ha mohaho o tšepe e corroded, joale thusa fokotsa ho timetsoa ha passivating additives le inhibitors. Kenya letsoho hore ho thibelo ya dithulaganyo ts'enyeho ka alkaline le libakeng nke lehlakore oxidants joalo matla joaloka alkaline lefatše le lirafshoa a alkali. Ho sireletsa matlafatso ho matlafatsoa ka konkreiti, sebediswa k'halsiamo nitrate-nitrite.

Ha u hloka tšireletso ts'enyeho, etsahala tlas'a tšusumetso ea tikoloho Link le pula sepakapakeng, sebelisa inhibitors hloka botsitso, e leng thepa eo adsorb holim'a holim tšepe ho tloha moeeng kapa le le khutsufalitsoeng hodima yona ho theha mokato mosesaane.
