Sulphuric acid kunye nokusetyenziswa kwayo

Sulphuric acid yenye Imichiza kakhulu kakuhle awaziwayo eqhelekileyo. Isizathu ikakhulu iipropati zayo kakuhle echazwe. ifomula Its - H2SO4. Oku diacid ukuba i eliphezulu igcwala karhulumente ngayo sulphur +6.

Phantsi kweemeko eziqhelekileyo sulphuric acid yi ulwelo ngaphandle ivumba kunye nombala, nokuba iimpawu ezinamafutha. Yaziwa ngokubanzi isasazeka ubugcisa kunye namashishini ezahlukeneyo.

Okwangoku, le nto yenye zemichiza zibalulekileyo kunye eziqheleke kakhulu imveliso yemichiza. Kwindalo, iidiphozithi sulphur lweenkobe kuzo hayi ngokufuthi kangangoko umthetho, ifumaneka kuphela xa iikhompawundi kunye nezinye izinto. Iphuhlisa imveliso iikhompawundi ezahlukeneyo sulphur, kubandakanywa iindidi umphutha mveliso. Kwezinye iimeko, iigesi iintsimbi ayoni ingatshintshwa apha naphaya ukuze zivelise isalfure kunye nemixube ezahlukeneyo kulo.

izakhiwo

Sulphuric acid kakubi kuchaphazela nayiphi ulungelelwaniso. Kuthatha amanzi kubo ngokukhawuleza kakhulu, kangangokuba le laphu kunye khompawundi ezahlukeneyo iqale Isakare. 100% acid yenye kakhulu, umchiza akatshayi aze ungayonakalisi iintsimbi ayoni.

Ukuxuba sulphuric acid idityaniswe naziphi na iintsimbi ngaphandle bakhokele. Xa ifomu kanzulu kokuba iqale oxidize izinto ezininzi.

Ukusetyenziswa kwe-sulphuric acid

Ikakhulu sulphuric acid isetyenziswa lweshishini lemichiza, apho lisekelwe imveliso nitrogen kunye nezichumiso phosphate, kuquka superphosphate, nto leyo okwangoku ingqalelo enye izichumisi ixhaphakileyo. Ngonyaka ukuvelisa phezulu ukuya kwiitoni ezingama abaliqela kweziyobisi.

Xa metallrugii H2SO4 isetyenziselwa ukukhangela umgangatho mveliso. Xa steel liqengqiwe micro-iintanda kunokwenzeka ukuze zibonwe, le nto ibekwe ngokuhlamba abaphambili kunye kwagxila% nesisombululo 25 acid. Emva koko, nkqu iintanda zincinane kunokubonwa ngeliso lenyama.

Ngaphambi kokuba nokusebenzisa i intsimbi kukujonga ukuba kuyimfuneko ukulungiselela ngaphambili - ukuwuhlamba degreased. Ekubeni sulphuric acid idityaniswe nesinyithi, oko iyachithakala umaleko obhityileyo, kunye isusa naliphi na ikhethe azingcolise. Ukongeza, umphezulu metal uba erhabaxa, nto leyo kangcono ukuba isicelo se-nickel, chromium okanye nesingxobo ubhedu.

Sulphuric acid isetyenziswa ekusetyenzweni kwezinye sisimbiwa, oko kwakhona isixa esikhulu efunekayo kwishishini oyile apho isetyenziswa ikakhulu ngenxa kungengokwentlambululo yendawo iimveliso ezahlukeneyo. Idla esetyenziswa kwishishini kwemichiza le, nto leyo eguqukayo. Ngenxa yoko, bafumana izakhono ezongezelelweyo kunye izicelo. Le eziphathekayo kusetyenziselwa ukuvelisa lead-asidi imithombo zangoku - neebhetri ezahlukeneyo.

Ukulungiswa kwe-sulphuric acid

Owona ekrwada izinto ku tswala isalfure acids bakhonza khompawundi ezahlukeneyo ezisekelwe kuyo. Ngaphezu koko, njengoko sele kuchaziwe, oko ekuphuhliseni ukusetyenziswa ezingasafunekiyo mveliso ukuvelisa nesalfure. Xa kaJohn oxidative ekrwada emanzini iigesi exhaust ziqulathe SO2. Ku afunekayo ukuvelisa sulphuric acid. Nangona Russia iyaqhubeka ukuba kweso sikhundla ehamba phambili kweli processing imveliso esekelezwe pyrite, nto leyo utshiswe wakwaMowabhi. Xa umoya phezu pyrites akhiwa iperi SO2 ophezulu. Ukuze kuphume kunye nezinye mphunga uyingozi kusetyenziswa electrostatic. Ngoku ke imveliso iindlela ezisetyenziswa ngokubanzi ezahlukeneyo ku tswala acid, kwaye uninzi lwabo ezinxulumene nolawulo lwenkunkuma, nangona umlinganiselo ophezulu lwamashishini zemveli.
