Iron oxide uye kugadzirira ayo chicherwa mbishi zvinhu

Mumwe munhu wokubasa mu basa mhuri dzavo pamwechete chinonakidza kuti ngura. Anoziva kuti ichi ndicho mugumisiro oxidation resimbi.

Sezvo ngura aumbwa?

Chero simbi chigadzirwa ine imwe mari dzesimbi chaikosha :. Steel ligature etc. It paChikoro rwokugadzirwa dzakawanda dzinotsanagura simbi dzakasiyana. Iron zvinowanikwa muvhu nechepasi. simbi iyi yakawedzerwa panguva kugadzirwa siyana zvakawanda, uye zvachose kubvisa zvinenge zvinopera naye, uye mune zvimwe zviitiko izvi hazvisi zvakakodzera. chaikosha ichi, kana ndiripo ari esimbi nyaya, pakupedzisira oxidized nendege, mwando, mvura, uye zvichiguma aumba pasi pemvura simbi oxide ndiyo 3. Chokwadi, zvigadzirwa zvemapuranga ane runodzivirira, asi zviri nyore kumedura kuburikidza pasi chero hwokugadzira kukanganisa kubva kurutivi.

Key ehupfumi

Iron oxide - sirivha simbi iri ductile chaizvo. It anongokurukurwa zvakanaka mhando dzakawanda machine: nokuchengetedza, rinopfungaira. Kukwanisa kwaro kukurumidza zhinji zvinhu zvikuru kushandiswa pakugadzira alloys zhinji. Active makemikari chaikosha interacts pamwe anenge zvose sanganisa acids yokuumba remubatanidzwa runoenzanirana Valencia. Asi achiita chaizvo tinyerere mune pfungwa yokushanda acids. simbi yakachena rakagadzirirwa nokuda hwokugadzira kubudiswa zvicherwa, iri aripo chaizvoizvo ane oxide nesimbi.

kubatana

Iron yeimwe vanoumba misara miviri: remubatanidzwa 2-valent uye 3-valent. Mumwe nomumwe wavo kunoratidzwa kwayo oxide. Kuvakwa simbi remubatanidzwa nokuda kuparadzwa muna acids. munyu simbi hydrolyze 3 zvakasimba, saka vane yeyero mashava ruvara, kunyange zvazvo chinhu chiri Hauoneki. Iron yeimwe vari zvinowanzoshandiswa simbi somunhu kuderedza mumiriri, muna National upfumi iri kudzorwa tupukanana vari Whitehead Textile indasitiri, etc. Anhydrous simbi oxide 2 yakagadzirirwa kubvira 3 ne rutapudzo oxide somunhu upfu dema, nepo kugadzirira resimbi oxide 3 kunoitika kuburikidza calcining simbi hydroxide 3. Oxides zvinokonzera kuwana munyu simbi. Pachine anozivikanwa zvishoma sezvo iine acid mukomboni uye mukomboni ane Valence pamusoro +6. Kana fused oxide 3 vakaumba ferrites uye ferrates, itsva, isati kwazvo kudzidza akakura.

Kuwanda zvakasikwa

The zvinorondedzerwa chaikosha uye ayo yeimwe vari rinoparadzirwa zvakasikwa. Muchimiro tsvuku, limonite simbi oxide 3 kumbowanikwa muchimiro magnetite - Fe3O4. Nokuti kugadzirwa sulfuric iine acid simbi pyrites (sulphide) rinoshandiswa. Oxides ndivo kwainyanya resimbi uye simbi. Steel nesimbi vane ndezvomuzana chete nziyo, musiyano chete ndiye kabhoni kugutsikana. Iron alloys ane asingasviki 2.14% kabhoni, steels dzinonzi, uye vanopfuura 2.14% - simbi. nokuparadzirwa uku hakusi akakodzera kunzwisisa steels akadai chiwanikwa, nokuti vane zvakawanda kunzwisisa chivakwa uye vanoonekwa nokuvapo zvimwe zvinhu.
