Corrosion chimwe chezvinhu zvakakosha zvinokonzeresa kukuvara kwevharuvhu.Mukudzivirira kwevharuvhu, kudzivirirwa kwekuora kwevhavha inyaya yakakosha yekufunga nezvayo.Kune mavharuvhu esimbi, kurapwa kwepamusoro pekuvhara ndiyo nzira yakanakisa yekudzivirira inodhura.
1. Kudzivirira
Mushure mokunge nzvimbo yesimbi yakaputirwa nepende, simbi yesimbi inenge iri yoga kubva kune zvakatipoteredza.Izvi zvinodzivirira zvinogona kunzi shielding effect.Asi zvinofanirwa kutaurwa kuti pende yakaonda yepende haigone kuita mhedziso yekudzivirira.Nekuti iyo yakakwira polymer ine kumwe kupindira kwemhepo, kana iyo yekupfeka iri mutete kwazvo, ma pores ayo echimiro anobvumira mamorekuru emvura uye okisijeni kupfuura zvakasununguka.Mavharuvhu akapfava ane chisimbiso chakasimba pane ukobvu hweepoxy coating pamusoro.Zvinogona kuonekwa kuti kune akawanda machira kukosha kwakakura kudarika simbi isina kuvharwa.Kuti uvandudze kusapindirana kwechifukidziro, iyo anti-corrosion coating inofanira kushandisa firimu-inogadzira chinhu nemhepo yakaderera permeability uye yakasimba filler ine pfuma huru yekudzivirira, uye panguva imwe chete, nhamba yezvipfeko zvekuputira zvinofanira kuwedzerwa. kuitira kuti kuvhara kunogona kusvika kune imwe hupamhi uye kuva dense uye kwete-porous.
2. Corrosion inhibition
Nekuita zvikamu zvemukati zvekuputira nesimbi, simbi yesimbi inopfuudzwa kana chinhu chinodzivirira chinogadzirwa kuti chivandudze maitiro ekudzivirira ekuvhara.Mavharuvhu anoshandiswa kune zvakakosha anofanirwa kutarisisa kuumbwa kwepende kuti adzivise mhedzisiro yakaipa.Uye zvakare, iyo yakakandwa simbi vharafu inoshandiswa mupombi yemafuta, izvo zvinosvibisa zvigadzirwa zvinogadzirwa pasi pekuita kwemamwe mafuta uye kuomesa sipo yesimbi zvinogona zvakare kuita basa re organic corrosion inhibitors.
3. Electrochemical protection
Electrochemical corrosion pasi pefirimu inoitika apo dielectric permeable coating inosangana nesimbi.Shandisa simbi dzine chiitiko chepamusoro pane simbi semazadza mumachira, senge zinc.Ichaita basa rekudzivirira rezvibairo anode, uye zvigadzirwa zvekuora zvezingi ndeye zinc chloride uye zinc carbonate, iyo inozadza gaka re membrane uye kuita kuti membrane ive yakasimba, iyo inoderedza zvakanyanya kuora uye inowedzera hupenyu hwesevhisi. vharafu.
