Ngura papurazi

Akadana ngura simbi oxide. Ngura - chiratidzo chokuti simbi kuonana kana yakachena kana mvura. Pamusoro pemvura yakachena simbi iri kazhinji zvematongerwo nezvinhu zvakadaro, chete oxidised simbi dziine zvimwe marara -. Carbon, sarufa, phosphorus, etc. Uyewo oxidative kurwisa angava munhu sarufa oxide uye carbon dioxide, iri mvura.

Ngura ngozi iri chokwadi chokuti zvinoputsa zvishoma nezvishoma nyaya zvakagadzirwa simbi kana kukandira simbi, zvishoma nezvishoma kuchinja chimiro chayo uye vhoriyamu. simbi oxidation chinoita rinoparadza basa.

Muzviitiko zvakawanda, kudzivisa ngura chinhu zvemapuranga chaiwo unhani kunyanya ichi kushandiswa chromium oxide. Asi zvakadini kana chiwanikwa iron oxidation kwacho vakatotanga?

Muchiitiko chino, zvinogona kubatsira ngura convert. It kwete chete hakubvisi oxidation zvishoma nezvishoma akaipa simbi asiwo kuti pave simba inodzivirira firimu kubva oxidation zvigadzirwa. Kumboda ngura convert rinoshandiswa kuitira kudzivirira pamusoro ngura design, akagadzirwa kabhoni kana yakaderera chiwanikwa steels. In ichi simbi oxide rukoko hakufaniri anopfuura 100 micrometers. Ngura kakawanda yakagadzirwa phosphoric asidhi uye hydroxycarboxylic acid, tannin, uye kunyange simende. Inogona kutengwa muchimiro ane emulsion, mhinduro kana kumisa.

-siyana nevamiririri vanoita nenzira dzakasiyana. Conventionally, vari mapoka mapoka makuru akawanda: ngura convert muvhu pasi paintwork; stabilizers, ngura zvigadzirwa, izvo kutendeutsa simbi oxide hydrate mudanga zvikuru makemikari remubatanidzwa; converters ngura zvigadzirwa, Ngura ikachinja kuva zvishoma soluble munyu; chaiye kupinda nziyo kuti zvinoodza tsindirana ngura zvigadzirwa.

Pakusarudza nzira kuti kushandisa mari kuti simbi pamusoro chinoita runokosha basa rimwe viscosity mumiririri. Zvichienderana ayo kusachinja-chinja, ngura convert vakashandisa aibuda unhani, kutiva, bhurasho kana spraying. Pamberi simbi pamusoro kufukidza runoenzanirana chimiro, zvakafanira kugadzirira. Zvakakodzera kuchenesa kure dura ngura zvinhu uye hombe akaturikidzana kuti ngura.

Converters vari contraindicated kushandiswa mune nguva iwayo apo oxidation kwakakonzerwa ne mhepo ine yakawanda amoniya, rehydrogen sulphide kana nesurferi dioxide.

Kana ngura kwakafukidza chero chikamu motokari yako, zvakakodzera kushandisa mhando chaidzo ngura convert lähikuva. Kubvisa yekare rukoko ngura uye haapi fomu panhurikidzwa imwe itsva. Mutumwa angachinja noruvara pemvura zvichienderana nemhando ngura. Chokutanga, gadzirai chinhu - kubvisa tsvina uye girisi, kana ivo varipo pamusoro payo. Wire mumakwenzi, bvisai ngura zvigadzirwa. Zvadaro sukurudza pamwe kusvibiswa residues pemvura. Zunzai pamberi kushandiswa ngura convert. The sezvamunoita rinoshandisirwa yakagadzirirwa pamusoro.
