Ndezvipi Zvikamu ZveMagetsi Ekuchenesa Mvura?

Mishonga yekuchenesa mvura inoreva makemikari anowedzerwa panguva yekuchenesa mvura kuti abvise zvinhu zvinokuvadza zvakawanda mumvura (senge zvinhu zvinoparadza, maion simbi, tsvina uye tupukanana, nezvimwewo) uye kuwana mvura yevagari kana yeindasitiri inoenderana nezvinodiwa. Mvura yekurapa mishonga iboka rakakosha rezvigadzirwa zvemakemikari zvakanaka uye zvine hunyanzvi hwakasimba. Zvishandiso zvakasiyana-siyana zvekurapa mvura zvinodiwa kune zvinangwa zvakasiyana uye zvinhu zvekurapa.

Nhanganyaya:

Mushandi wekuchenesa mvura ishoko rakajairwa remakemikari anoshandiswa pakuchenesa mvura, ayo anoshandiswa zvakanyanya muzvikamu zveindasitiri senge peturu, indasitiri yemakemikari, simbi, zvekufambisa, indasitiri yemwenje, uye machira. Mishonga yekuchenesa mvura inosanganisira corrosion inhibitors, scale inhibitors, bactericides, flocculants, purifiers, cleaner agents, pre-filming agents, nezvimwewo. Mukushandiswa kunoshanda, mishonga yekuchenesa mvura ine mafomu emukomboni inowanzoshandiswa, kana mishonga yakasiyana-siyana yekuchenesa mvura inoshandiswa pamwe chete. Naizvozvo, zvinodikanwa kuti titarise kupokana kuri pakati pezvikamu nekuda kwekusanganisa kusingakodzeri, izvo zvinoderedza kana kurasikirwa nemhedzisiro, uye kushandisa zvizere synergistic athari (iyo synergistic effect inogadzirwa kana akawanda maajenti aripo) kuwedzera mhedzisiro. Pamusoro pezvo, masisitimu mazhinji ekurapa emvura ndiwo masisitimu akavhurika ane humwe huwandu hwekubuda. Paunenge uchiashandisa, kukanganisa kweakasiyana-siyana ekuchenesa mvura pane zvakatipoteredza kunofanirwa kutariswa. Zvishandiso zvakajairika zvekurapa mvura zvinosanganisira: flocculants, ferrous sulfate heptahydrate, polyferric munyu, calcium hydroxide, ferric chloride hexahydrate, bactericides uye algaecides, chlorine dioxide, scale inhibitors uye corrosion inhibitors, polyacrylamide (cationic, anionic, non-ilumionic chlorinic), ferric chloride, ferrous sulfate, nezvimwewo.

 

Corrosion inhibitors
Kirasi yemakemikari anogona kudzivirira kana kudzikamisa kukora kwezvinhu zvesimbi kana midziyo nemvura mushure mekuwedzera kumvura muhuwandu hwakakodzera uye mafomu. Ivo vane hunhu hwekuita kwakanaka, kuderera dosi, uye nyore kushandisa. Kune marudzi akawanda uye marudzi e corrosion inhibitors. Zvinoenderana nerudzi rwemakomponi avo, anogona kukamurwa kuita inorganic corrosion inhibitors uye organic corrosion inhibitors. Zvinoenderana nekuti maitiro avanodzivisa ndeye anodic reaction, cathodic reaction, kana ese ari maviri, anogona kukamurwa kuita anodic corrosion inhibitors, cathodic corrosion inhibitors, kana yakasanganiswa corrosion inhibitors. Corrosion inhibitors inogona zvakare kukamurwa kuita passivation film type, precipitation film type, uye adsorption film type zvinoenderana nemagadzirirwo ekugadzira firimu rinodzivirira pane simbi. Inowanzoshandiswa passivation film type corrosion inhibitors mukurapa kwemvura inosanganisira chromates, nitrites, molybdates, nezvimwewo; inowanzoshandiswa kunaya kwefirimu mhando corrosion inhibitors inosanganisira polyphosphates, zinc munyu, nezvimwewo; inowanzoshandiswa adsorption film type corrosion inhibitors inosanganisira organic amines, nezvimwe.
Dispersant
Chekutanga scale inhibitor dispersant yaive polyacrylic asidhi (sodium), ine chiyero chakanaka chekudzivisa kuita kurwisa calcium carbonate scale, asi ine yakanyanya kuderera inhibitory mhedzisiro pacalcium phosphate deposition.
