Sulfuric asidhi uye kushandiswa kwayo

Sulfuric asidhi ndechimwe chezvinhu inozivikanwa uye zvakafanana makemikari. Chikonzero kuchikonzerwa ayo ehupfumi yakajeka. fomura Its - H2SO4. Izvi diacid ane rokumusoro oxidation mamiriro rwesarufa +6.

Under kwomuzvarirwo ezvinhu sulfuric asidhi imvura pasina zvakanaka uye ruvara, ane jikichira maitiro. Vakawanda kunyenga unyanzvi uye maindasitiri akasiyana-siyana.

Panguva iyoyo, fuma iyi ndeimwe anokosha uye Inonyanya makemikari uye nemakemikari zvigadzirwa. Zvakasikwa, chizvarwa sarufa deposits mhiri kudaro kakawanda sezvinoita mutemo, inowanikwa chete yeimwe nevamwe zvinhu. Zvinonzi kugadzira kugadzirwa siyana sarufa yeimwe, kusanganisira dzakasiyana-siyana maindasitiri kunouraya. Mune zvimwe zviitiko, magasi ferrous nesimbi zvinogona dzakashandisa kubereka sarufa siyana yeimwe mairi.

ehupfumi

Sulfuric asidhi kukanganisa chero makemikari akakura. Zvinotora mvura kwavari nokukurumidza, saka kuti chinokosha uye siyana yeimwe dzinotanga kwaIsakari. 100% asidhi mumwe akasimba, mukomboni hakuiti kuputa uye hachiparadzi ferrous simbi.

Sanganisa sulfuric asidhi ikasakendenga chero nesimbi kunze mutobvu. In kuramba fomu rwunotanga oxidize zhinji zvinhu.

Kushandiswa sulfuric asidhi

Kunyanya sulfuric asidhi rinoshandiswa makemikari indasitiri, apo zvakavakirwa zvibereko senitrogen uye phosphate fetiraiza, kusanganisira superphosphate, iyo pari vaiona chimwe chezvinhu zvakafanana fetiraiza. Gore negore kubudisa kumusoro mamiriyoni akawanda matani nefuma kuti.

In metallrugii H2SO4 rinoshandiswa kutarisa unhu zvigadzirwa. Kana rwuchipeterwa simbi Micro-makatsemuka zvingaitika kuti rione navo, chinhu anoiswa achitungamirira kugeza uye chinopinda 25% mhinduro kubva acid. Pashure paizvozvo, kunyange zviduku makatsemuka inogona kuonekwa chinoabatsira.

Asati kushandisa simbi ra zvakakodzera kare kugadzirira - kucheneswa uye degreased. Sezvo sulfuric asidhi ikasakendenga pamwe simbi, naro urwa dzakaonda layer uye naro anobvisa kutombosvibiswa zvisaririra. Mukuwedzera, simbi pamusoro inova ine ndiro nani akakodzera kuti kushanda nickel, chromium kana mhangura yakanamirwa pamifananidzo.

Sulfuric asidhi rinoshandiswa kubudiswa zvimwe ores, zviri zvakare inokosha mari yaidikanwa mumafuta indasitiri apo rinoshandiswa zvikurukuru wokunatswa zvinhu zvakasiyana-siyana. It rinowanzoshandiswa makemikari indasitiri, iyo nguva dzose Virtual. Somugumisiro, vakaona mamwe nezvaanogona uye mafomu. Izvi zvinhu zvinogona kushandiswa pakugadzira mutobvu-asidhi iyezvino zvinyorwa - siyana mabhatiri.

Kugadzirira sulfuric asidhi

Huru mbishi zvinhu hwokubereka sarufa acids kushumira yeimwe siyana anoritsanangura. Uyezve, sezvo kare ambotaurwa, zviri kuva kushandiswa maindasitiri matongo dzokugadzira nesarufa. Mugore oxidative roasting kuti sulfide ores chiutsi magasi ane SO2. Zvinonzi dzakashandisa kubereka sulfuric acid. Kunyange Russia anopfuurira yepasisa aitungamirira chinzvimbo pakuburitswa anotsanangura kubudiswa pyrite, iro inopiswa yamavira. Kana mhepo inopisa pamusoro pyrites vari aumba peya soro SO2. Kubvisa tsvina uye dzimwe vapor ngozi electrostatic kushandiswa. Zvino kugadzirwa nevakawanda akashandisa nzira dzakasiyana hwokubereka acid, uye vazhinji vavo vari ukama kupambadza utariri, kunyange yakakwirira inorwara zvetsika maindasitiri.
