Ferrous Sulphate Heptahydrate

Chiyambi chachidule：

Ferrous sulfate heptahydrate, yomwe imadziwika kuti green alum, ndi chinthu chosapangidwa ndi zinthu zachilengedwe chomwe chili ndi fomula ya FeSO4·7H2O. Amagwiritsidwa ntchito kwambiri popanga mchere wachitsulo, inki, magnetic iron oxide, choyeretsera madzi, chophera tizilombo toyambitsa matenda, chothandizira chitsulo; Amagwiritsidwa ntchito ngati utoto wa malasha, choyeretsera khungu, choyeretsera bleach, chosungira matabwa ndi chowonjezera cha feteleza, komanso kukonza ferrous sulfate monohydrate. Katundu, ntchito, kukonzekera ndi chitetezo cha ferrous sulfate heptahydrate zafotokozedwa mu pepalali.

Chilengedwe

Ferrous sulfate heptahydrate ndi kristalo wabuluu wokhala ndi dongosolo labwino la makristalo osinthasintha komanso kapangidwe kabwino ka hexagonal komwe kamakhala kozungulira.

Ferrous sulfate heptahydrate ndi madzi a kristalo omwe amatayidwa mosavuta mumlengalenga ndikukhala anhydrous ferrous sulfate, yomwe imatha kuchepetsedwa kwambiri komanso kusungunuka.

Madzi ake ndi acidic chifukwa amawola m'madzi kuti apange sulfuric acid ndi ferrous ions.

Ferrous sulfate heptahydrate ili ndi kuchuluka kwa 1.897g/cm3, kutentha kosungunuka kwa 64 ° C ndi kutentha kowira kwa 300 ° C.

Kukhazikika kwake pa kutentha n’kochepa, ndipo n’kosavuta kuwola kutentha kwambiri kuti apange mpweya woipa monga sulfur dioxide ndi sulfur trioxide.

Kugwiritsa ntchito

Ferrous sulfate heptahydrate imagwiritsidwa ntchito kwambiri m'makampani.

Choyamba, ndi gwero lofunika la chitsulo, lomwe lingagwiritsidwe ntchito pokonzekera mankhwala ena achitsulo, monga ferrous oxide, ferrous hydroxide, ferrous chloride, ndi zina zotero.

Kachiwiri, ingagwiritsidwe ntchito pokonza mankhwala monga mabatire, utoto, zinthu zoyambitsa matenda, ndi mankhwala ophera tizilombo.

Kuphatikiza apo, ingagwiritsidwenso ntchito pochiza madzi otayidwa, kuchotsa sulfurization, kukonzekera feteleza wa phosphate ndi zina.

Kufunika kwa ferrous sulfate heptahydrate n'kodziwikiratu, ndipo kuli ndi ntchito zosiyanasiyana popanga mafakitale.

Njira yokonzekera

Pali njira zambiri zopangira ferrous sulfate heptahydrate, ndipo njira zodziwika bwino ndi izi:

1. Kukonzekera kwa sulfuric acid ndi ufa wa ferrous.

2. Kukonzekera kwa sulfuric acid ndi ferrous ingot reaction.

3. Kukonzekera kwa sulfuric acid ndi ammonia yachitsulo.

Tiyenera kudziwa kuti momwe zinthu zimachitikira ziyenera kuyendetsedwa mosamala panthawi yokonzekera kuti tipewe mpweya woipa komanso kutayika kosafunikira.

Chitetezo

Ferrous sulfate heptahydrate ili ndi chiopsezo china, choncho muyenera kulabadira mfundo zotsatirazi:

1. Ferrous sulfate heptahydrate ndi mankhwala oopsa ndipo sayenera kukhudzidwa mwachindunji. Kupuma, kumeza, komanso kukhudza khungu ndi maso kuyenera kupewedwa.

2. Pokonzekera ndi kugwiritsa ntchito heptahydrate ya ferrous sulfate, muyenera kusamala kuti mupewe mpweya woopsa komanso zoopsa za moto ndi kuphulika.

3. Posungira ndi kunyamula, muyenera kusamala kuti mupewe kukhudzana ndi mankhwala monga ma oxidants, ma acids ndi ma alkali kuti mupewe kukhudzana ndi zinthu zina komanso ngozi.

Chidule

Mwachidule, ferrous sulfate heptahydrate ndi chinthu chofunikira kwambiri cha inorganic ndipo chimagwiritsidwa ntchito m'njira zosiyanasiyana.

Mu mafakitale opanga ndi ma laboratories, chisamaliro chiyenera kuperekedwa ku zoopsa zake, ndipo njira zoyenera ziyenera kutengedwa posungira, kunyamula ndi kugwiritsa ntchito kuti zitsimikizire chitetezo cha munthu payekha komanso kuteteza chilengedwe.

Nthawi yomweyo, chisamaliro chiyenera kuperekedwa pakusunga chuma panthawi yogwiritsa ntchito kuti tipewe zinyalala ndi kuipitsa.
