Chiyambi chachidule:
Ferrous sulfate heptahydrate, yomwe imadziwika kuti green alum, ndi inorganic pawiri ndi chilinganizo FeSO4 · 7H2O.Amagwiritsidwa ntchito makamaka popanga chitsulo mchere, inki, maginito chitsulo okusayidi, madzi kuyeretsa wothandizira, tizilombo toyambitsa matenda, chitsulo chothandizira;Amagwiritsidwa ntchito ngati utoto wa malasha, pofufuta, bleaching wothandizila, zosungira nkhuni ndi zowonjezera zowonjezera feteleza, ndi kukonza ferrous sulfate monohydrate.The katundu, ntchito, kukonzekera ndi chitetezo cha ferrous sulfate heptahydrate akuyambitsidwa mu pepalali.
Chilengedwe
Ferrous sulfate heptahydrate ndi galasi labuluu lomwe lili ndi mawonekedwe osinthika a kristalo komanso mawonekedwe odzaza ndi hexagonal.
Ferrous sulfate heptahydrate ndikosavuta kutaya madzi a kristalo mumlengalenga ndikukhala anhydrous ferrous sulfate, omwe ali ndi kuchepetsedwa amphamvu komanso makutidwe ndi okosijeni.
Madzi ake amadzimadzi amakhala acidic chifukwa amawola m'madzi kupanga sulfuric acid ndi ayoni achitsulo.
Ferrous sulfate heptahydrate ili ndi kachulukidwe ka 1.897g/cm3, malo osungunuka ndi 64 ° C ndi kuwira kwa 300 ° C.
Kukhazikika kwake chifukwa cha kutentha kumakhala koipa, ndipo n’kosavuta kuwola pa kutentha kwambiri kutulutsa mpweya woipa monga sulfure dioxide ndi sulphur trioxide.
Kugwiritsa ntchito
Ferrous sulfate heptahydrate imagwiritsidwa ntchito kwambiri m'makampani.
Choyamba, ndi gwero lofunika lachitsulo, lomwe lingagwiritsidwe ntchito pokonzekera mankhwala ena achitsulo, monga ferrous oxide, ferrous hydroxide, ferrous chloride, etc.
Kachiwiri, itha kugwiritsidwa ntchito popanga mankhwala monga mabatire, utoto, zopangira, ndi mankhwala ophera tizilombo.
Kuphatikiza apo, itha kugwiritsidwanso ntchito pochiza madzi oyipa, desulfurization, kukonzekera feteleza wa phosphate ndi zina.
Kufunika kwa ferrous sulfate heptahydrate kumawonekera, ndipo kumakhala ndi ntchito zambiri pakupanga mafakitale.
Njira yokonzekera
Pali njira zambiri zopangira ferrous sulfate heptahydrate, ndipo njira zodziwika bwino ndi izi:
1. Kukonzekera kwa sulfuric acid ndi ferrous ufa.
2. Kukonzekera kwa sulfuric acid ndi ferrous ingot reaction.
3. Kukonzekera kwa sulfuric acid ndi ferrous ammonia.
Kuyenera kudziŵika kuti anachita zinthu ayenera mosamalitsa ankalamulira pa kukonzekera ndondomeko kupewa zoipa mpweya ndi zosafunika zomvetsa.
Chitetezo
Ferrous sulfate heptahydrate ali ndi chiopsezo china, ayenera kulabadira mfundo zotsatirazi:
1. Ferrous sulfate heptahydrate ndi mankhwala oopsa ndipo sayenera kukhudza mwachindunji.Kukoka mpweya, kumeza ndi kukhudzana ndi khungu ndi maso kuyenera kupewedwa.
2. Pokonzekera ndi kugwiritsa ntchito ferrous sulfate heptahydrate, chisamaliro chiyenera kutengedwa kuti tipewe mpweya woipa ndi zoopsa zamoto ndi kuphulika.
3. Pakusungirako ndi kunyamula, chisamaliro chiyenera kuperekedwa kuti tipewe kukhudzana ndi mankhwala monga okosijeni, ma acid ndi alkalis kuti apewe zochitika ndi ngozi.
Chidule
Mwachidule, ferrous sulfate heptahydrate ndi yofunika inorganic pawiri ndipo ali osiyanasiyana ntchito.
Pakupanga mafakitale ndi ma labotale, chidwi chiyenera kulipidwa pachiwopsezo chake, ndipo njira zoyenera ziyenera kuchitidwa kuti zisungidwe, zoyendetsa ndikugwiritsa ntchito kuti zitsimikizire chitetezo chamunthu komanso kuteteza chilengedwe.
Panthawi imodzimodziyo, chidwi chiyenera kuperekedwa pakupulumutsa chuma pakugwiritsa ntchito kuti tipewe kuwononga ndi kuipitsa.
