Simbi inoreva simbi ine simbi sechinhu chikuru, kabhoni yemukati kazhinji pazasi 2.0% uye zvimwe zvinhu.Musiyano uripo pakati payo nesimbi ndiyo carbon content.Inofanira kutaurwa kuti yakasimba uye yakasimba kudarika iron.Kunyange zvazvo isiri nyore kuita ngura, zvakaoma kuvimbisa kuti ichaitwa ngura.Kana ikaita ngura uye isina kurapwa nenguva, inova nyore kuita ngura.Rasa kushanda kwayaifanira kuva nayo.

Kana pombi yesimbi isina musono yaita ngura, ndedzipi nzira dzakajairika dzekurapa?Vamwe vanhu vachashandisa nzira yekuchenesa kuchenesa pombi yesimbi isina tsvina.Paunenge uchichenesa, pamusoro pesimbi inofanira kucheneswa ne solvent uye emulsion kutanga.Iyi nzira inoshandiswa chete senzira yekubatsira ye-anti-corrosion uye haigoni kunyatsobvisa pombi yesimbi isina tsvina.kuita ngura.Tinogonawo kushandisa mabhurashi esimbi, mabhora ewaya uye zvimwe midziyo kubvisa yakasununguka oxide sikero uye ngura pamusoro pepamusoro tisati tachenesa, asi kana isu tisati tatora matanho ekudzivirira, inoparadzwa zvakare.

Pickling zvakare imwe yenzira dzekubvisa ngura.Kazhinji, nzira mbiri dzemakemikari uye electrolysis dzinoshandiswa pakunhonga kurapa, uye chete kemikari pickling ndiyo inoshandiswa pombi inodzivirira kupisa.Kunyange zvazvo nzira iyi inogona kuwana imwe chiyero chehutsanana, zviri nyore kukonzera kusvibiswa kune zvakatipoteredza, saka hazvikurudzirwi kuishandisa.

Uchishandisa jet derusting, high-power motor inotyaira jet blades kuti itenderere nekumhanya zvakanyanya, zvekuti mabrasives akadai sesimbi grit, simbi kupfura, iron wire segment, uye zvicherwa zvinoiswa pamusoro pepombi yesimbi isina tsvina pasi pekuita kwe centrifugal force.Kwete chete inogona kuita ngura, oxides uye tsvina kubviswa zvachose, asi pombi yesimbi inogonawo kuwana inodiwa yunifomu roughness pasi pechiito chechisimba chechisimba uye kuputika kweabrasive.Kupfapfaidza ngura kubvisa inzira yakanaka yekubvisa ngura mupombi anticorrosion nzira.Pakati pazvo, dzidziso dzakawanda dzemuviri dzinoshandiswa, kusvibiswa kune zvakatipoteredza kuduku, uye kuchenesa kwakanyatsonaka.
