Zinc Sulfate Heptahydrate inonziwo Zinc Vitriol uye Alum Vitriol. Yayo morecular misa ndeye 287.56. Kutaridzika kwayo kuchena machena kana hupfu. Iyo ndeyako yeOrthorhombic Crystal system uye dens yaro yakaenzana ndeye 1.97. Iyo zvishoma nezvishoma inopisa mumhepo yakaoma. Nzira huru yekugadzira inosanganisira sulfutic acid nzira uye Smithsonite nzira.
Iyo Sulfac Actic nzira inoshandiswa kugadzira zinc sulfate hepthydrate, izvo zvinoshandiswa neslfunding zvinhu zvakashata, zvakaremara zinc oxder, zvakasara zveZinc oxder ferrous metallurgical indasitiri, uye zinc slag uye zinc minizi, etc.
Zvigadzirwa zveZinc zvinopwanywa nebhora chigayo uye chisina kuderedzwa ne 18% kusvika 25% sulfutic acid. Kupararira kunoitwa mune yekuita keteti yakamanikidzwa nezvinhu zvakashata-zvinodzivirira, zvakadai sekutungamira, uye zvakashongedzerwa nemukurumbira. Iyo nzira yekugadzirisa ndeye inotevera:
ZN + H2SO4 → ZNSO4 + H2 ↑ Zno + H2So4 → ZNSO4 + H2O
Iyo maitiro ndeye Exothermic uye tembiricha inosimuka pamusoro 80 ° C. Kana zvinyorwa zvacho zvine huwandu hwakawanda hwe simbi zinc, huwandu hukuru hwe hydrogen uchagadzirwa. Naizvozvo, iyo yekugadzirisa inofanirwa kuve yakagadzirirwa neisimba rakasimba rekupedza simba. Kuti ubate mwero wekutsanangura mune imwe nhanho inotevera yekuita, yakawandisa zinc-ine zvinhu zvinogona kuwedzerwa. Iyo pH kukosha pakupera kwekuita kunodzorwa kutenderera ne5.1, uye slurry inojekeswa uye yakasviba. Zvirimo zveZinc mune yefaira yakasara inofanirwa kunge iri pasi pe5%. Pamusoro peZinc Sulfate, iyo filtrate ine zvakare Sulfate inoenderana neyesimbi yakasvibiswa mune zvigadzirwa zvemidziyo. Kubvisa tsvina kunogona kuitwa mumatanho maviri. Kutanga, mhangura, nickel, nezvimwewo zvinobviswa, uye simbi yabviswa. Iyo filtrate inopisa kusvika 80 ° C mune yeZinc Powder inowedzerwa, uye musanganiswa unomutswa nesimba kwemaawa mana kusvika matanhatu kusvika matanhatu. Sezvo zinc ine yakaderera yekudzora mukana kupfuura mhangura, Nickel, uye Cadmium, aya masimbi anogona kudzingwa kubva kumhinduro. Iyo nzira yekugadzirisa ndeye inotevera:
Zn + Cuwa4 → ZNSO4 + Cuzn + Niso4 → ZNSO4 + Nizn + CDSO4 → ZNSO4 + CD
Iyo mhinduro yakatsaurwa inoshandurwa nekumanikidzwa kubvisa yakanaka madhaka simbi slag. Iyo filtrate inotumirwa kune ye oxidation ndiro, inopisa kusvika 80 ca, uye sodium hypochlorite, potassium permonganate, manganese dioxide, etc. inowedzerwa kune oxidhi iyo yakakwirira-yakaenzana nesimbi. Mushure me oxidation, huwandu hwakakodzera hwe lime rakawedzerwa. Mukaka wekuperekedza iyo yakakwira-Valent Iron Hydroxide wobva wobva waenda. Paunenge uchishandisa kusarura Poda, bika iyo mhinduro mushure mekunyepedzera kuparadza iyo yakasara yakasanganiswa poda. Paunenge uchishandisa potassium permananate, zinc oxide inogona kuwedzerwa kugadzirisa iyo ph kukosha kwemhinduro kune 5.1 nekuda kwekunyepedzera kweasodhi yemahara. Iyo filtrate inozotariswa nekupakwa, yakatonhorera kusvika pazasi 25 ° C, uye zinc sulfate heptahydrate zngecho4 · 4h2o makristuru anopindirana, iyo inogona kudzvanywa uye yakaoma.
