Muinjiniya inoshanda, kune nzira nhatu huru dzekudzivirira dzesimbi corrosion.
1.Nzira yekudzivirira yefirimu
Iyo firimu yekudzivirira inoshandiswa kuparadzanisa simbi kubva kune yakakomberedza, kudzivirira kana kunonoka kuparara kwekunze kwekunze kunopisa mukati mesimbi.Semuenzaniso, pfapfaidza pendi, enamel, plastiki, nezvimwewo pamusoro pesimbi;kana kushandisa simbi yekuputira sefirimu inodzivirira, senge zinc, tini, chromium, nezvimwe.
2.Electrochemical protection method
Icho chaicho chikonzero chekuora chinogona kukamurwa kuva kwete-ikozvino yekudzivirira nzira uye yakanakidzwa yazvino nzira yekudzivirira.
Iyo isina-ikozvino yekudzivirira nzira inonziwo chibayiro anode nzira.Iko kubatanidza simbi inoshanda kupfuura simbi, yakadai se zinc uye magnesium, kune chimiro chesimbi.Nekuti zingi nemagnesium zvine simba rakaderera pane simbi, zingi, uye magnesium inova anode yebhatiri rekuora.yakakuvadzwa (anode yechibairo), nepo chimiro chesimbi chinodzivirirwa.Iyi nzira inowanzo shandiswa kunzvimbo dzisiri nyore kana kusingagoneki kuvhara iyo yekudzivirira, senge mabhoilers emvura, mapaipi epasi pevhu emabhomba engarava, zvivakwa zveinjiniya, migwagwa uye zvivakwa zvebhiriji, nezvimwe.
Iyo inoshandiswa ikozvino nzira yekudzivirira ndeyekuisa imwe simbi yakarashika kana imwe simbi inomira padhuze nesimbi chimiro, senge yakakwira-silicon iron uye lead-silver, uye kubatanidza iyo yakaipa danda rekunze DC magetsi kune yakachengetedzwa simbi chimiro, uye iyo danda rakanaka rakabatana kune refractory simbi chimiro.Pamusoro pesimbi, mushure mekugadzira magetsi, simbi inopikisa inova anode uye yakasvibiswa, uye chimiro chesimbi chinova cathode uye chinodzivirirwa.
3.Nhoroondo ye Taijin Chemical
Simbi yekabhoni inowedzerwa nezvinhu zvinokwanisa kuvandudza corrosion resistance, senge nickel, chromium, titanium, mhangura, nezvimwewo, kugadzira simbi dzakasiyana.
Nzira dziri pamusoro apa dzinogona kushandiswa kudzivirira kukoromoka kwesimbi dzesimbi mukongiri yakasimbiswa, asi iyo inonyanya hupfumi uye inoshanda nzira ndeyekuvandudza density uye alkalinity yekongiri uye kuve nechokwadi chekuti simbi dzesimbi dzine zvakakwana zvekudzivirira layer ukobvu.
Mune simende hydration chigadzirwa, nekuda kwe calcium hydroxide inenge 1/5, pH kukosha kwepakati inenge 13, uye kuvapo kwe calcium hydroxide kunokonzera passivation firimu pamusoro pesimbi bar kuti iite chidziviriro chekudzivirira.Panguva imwecheteyo, calcium hydroxide inogonawo kuita neatmospheric clock CQ kuderedza alkalinity yekongiri, iyo passivation firimu inogona kuparadzwa, uye nzvimbo yesimbi iri mu activated state.Munzvimbo ine hunyoro, electrochemical corrosion inotanga kuitika pamusoro pesimbi yesimbi, zvichiita kuti kuputika kwekrete pamwe chete nebhari.Naizvozvo, iyo carbonization kuramba kwekongiri inofanirwa kuvandudzwa nekuvandudza compactness yekongiri.
Mukuwedzera, chloride ions ine mhedzisiro yekuparadza passivation firimu.Nokudaro, pakugadzirira kongiri yakasimbiswa, chiyero chekloridi munyu chinofanira kuderedzwa.
