Mabatiro atinoita ngura pane yakawedzerwa simbi mesh guardrail ndeaya anotevera:
1. Shandura chimiro chemukati chesimbi
Semuenzaniso, kugadzira akasiyana corrosion-resistant alloys, akadai sekuwedzera chromium, nickel, nezvimwewo kusimbi yakajairika kugadzira simbi isina tsvina.
2. Nzira yekudzivirira
Kuvhara pamusoro pesimbi nemudziyo wekudzivirira kunoparadzanisa chigadzirwa chesimbi kubva kune yakatenderedza corrosive medium kudzivirira ngura.
(1). Pfekedza pamusoro pesimbi yakawedzerwa mesh neoiri yeinjini, petroleum jelly, pendi kana kuivhara nezvinhu zvisingadzivirirwe nesimbi zvakaita seenamel nepurasitiki.
(2). Shandisa electroplating, kupisa kupisa, kupfapfaidza plating uye dzimwe nzira dzekupfekedza pamusoro pendiro yesimbi ine simbi isina kusvibiswa nyore, yakadai sezingi, tini, chromium, nickel, etc. Masimbi aya anowanzoita dense oxide film nekuda kweoxidation, nokudaro kudzivirira mvura nemhepo kubva kune simbi inoora.
(3). Shandisa nzira dzemakemikari kuumba firimu rakanaka uye rakagadzikana reoxide pane pamusoro pesimbi. Semuenzaniso, firimu rakanaka rakasviba ferric oxide rinoumbwa pamusoro pesimbi yesimbi.
3. Electrochemical protection method
Nzira yekudzivirira ye electrochemical inoshandisa musimboti we galvanic masero kuchengetedza simbi uye inoedza kubvisa galvanic cell reactions inokonzera galvanic corrosion. Electrochemical dziviriro nzira dzakakamurwa kuita mapoka maviri: anode kudzivirira uye cathodic kudzivirira. Iyo inonyanya kushandiswa nzira ndeye cathodic kudzivirira.
4. Bata corrosive media
Bvisa corrosion media, sekugara uchipukuta midziyo yesimbi, kuisa ma desiccants mumidziyo yakanyatsonaka, uye kuwedzera zvishoma zvecorrosion inhibitors izvo zvinogona kudzikisa kukora kune corrosion media.
5. Electrochemical protection
1. Chibayiro chekudzivirira anode nzira: Iyi nzira inobatanidza simbi inoshanda (yakadai se zinc kana zinc alloy) kune simbi inofanira kuchengetedzwa. Kana galvanic corrosion ikaitika, iyi simbi inoshanda inoita seyakaipa electrode kuti iite oxidation reaction, nokudaro kuderedza kana kudzivirira Corrosion yesimbi yakachengetedzwa. Iyi nzira inowanzoshandiswa kuchengetedza mirwi yesimbi uye mabhomba ezvikepe zvegungwa mumvura, zvakadai sekuchengetedzwa kwemasuo esimbi mumvura. Zvidimbu zvinoverengeka zvezingi zvinowanzoiswa pazasi pemutsetse wemvura wedeko rechikepe kana pachidzoreso pedyo nepropeller kudzivirira hull, nezvimwe.
2. Yakafadzwa ikozvino nzira yekudzivirira: Batanidza simbi kuti ichengetedzwe kune yakaipa danda remagetsi, uye sarudza imwe chidimbu che conductive inert zvinhu kuti ubatanidze kune yakanaka danda remagetsi. Mushure mekupa simba, kuunganidzwa kwemhosva dzisina kunaka (maerekitironi) kunoitika pamusoro pesimbi, nokudaro kuvharidzira simbi kubva pakurasikirwa nemaerekitironi uye kuzadzisa chinangwa chekudzivirira. Iyi nzira inonyanya kushandiswa kudzivirira kuora kwemidziyo yesimbi muvhu, mvura yegungwa uye mumvura yerwizi. Imwe nzira yekudzivirira kwe electrochemical inonzi anode protection, inova nzira iyo anode inopfuudzwa mukati meimwe nzira inogoneka nekushandisa kunze kwemagetsi. Inogona kuvhara kana kudzivirira midziyo yesimbi kubva mukuora muasidhi, alkali uye munyu.
