Folasaga puupuu：
Ferrous sulfate heptahydrate, e masani ona taʻua o le alum lanumeamata, o se mea faʻapitoa faʻatasi ma le fua FeSO4 · 7H2O. E masani ona faʻaaogaina i le gaosiga o le masima uʻamea, vaitusi, maneta uʻamea oxide, vai faʻamamaina sui, faʻamaʻi, faʻamaʻi uʻamea; E faʻaaogaina e pei o le koale vali, faʻamaʻi paʻu, vailaʻau faʻamaʻi, faʻasao laupapa ma faʻapipiʻi faʻapipiʻi faʻapipiʻi, ma le gaosiga o le sulfate monohydrate.
natura
Ferrous sulfate heptahydrate o se tioata lanumoana faʻatasi ai ma se faʻaogaina tioata lelei ma se fausaga faʻapipiʻi faʻapipiʻi masani.
Ferrous sulfate heptahydrate e faigofie ona leiloa vai tioata i le ea ma avea anhydrous ferrous sulfate, lea e malosi reducibility ma oxidation.
O lona vaifofo vai e fa'asa'o ona e pala i le vai e maua ai le sulfuric acid ma ion ferrous.
Ferrous sulfate heptahydrate o loʻo i ai le mamafa o le 1.897g/cm3, o le liusuavai o le 64 ° C ma le vevela o le 300 ° C.
E leaga le mautu o le vevela, ma e faigofie ona pala i le vevela maualuga e maua ai kasa leaga e pei ole sulfur dioxide ma le sulfur trioxide.
Fa'aaogāga
Ferrous sulfate heptahydrate e masani ona faʻaaogaina i alamanuia.
Muamua, o se puna taua o le uʻamea, lea e mafai ona faʻaaogaina e saunia ai isi uʻamea uʻamea, e pei o le oxide ferrous, ferrous hydroxide, ferrous chloride, ma isi.
Lona lua, e mafai ona faʻaaogaina e saunia ai vailaʻau e pei o maʻa, vali, faʻamalosi, ma vailaau faʻasaina.
E le gata i lea, e mafai foi ona faʻaaogaina i le vai otaota, desulfurization, phosphate fertilizer preparation ma isi vaega.
O le taua o le ferrous sulfate heptahydrate o loʻo faʻaalia e ia lava, ma o loʻo i ai le tele o faʻaoga i le gaosiga o pisinisi.
Auala sauniuni
E tele auala mo le saunia o le ferrous sulfate heptahydrate, ma o auala masani e faʻapea:
1. Sauniuniga ole sulfuric acid ma ferrous powder.
2. Sauniuniga o le sulfuric acid ma le ferrous ingot reaction.
3. Sauniuniga ole sulfuric acid ma ferrous ammonia.
E tatau ona maitauina o tulaga faʻaalia e tatau ona matua faʻatonutonuina i le taimi o sauniuniga e aloese ai mai kasa faʻaleagaina ma gau le manaʻomia.
Saogalemu
Ferrous sulfate heptahydrate ei ai se tulaga lamatia, e tatau ona gauai atu i vaega nei:
1. Ferrous sulfate heptahydrate ose mea oona ma e le tatau ona pa'i sa'o. O le inhalation, ingestion ma le faʻafesoʻotaʻi ma le paʻu ma mata e tatau ona aloese mai ai.
2. I le sauniuniga ma le fa'aogaina o le ferrous sulfate heptahydrate, e tatau ona fa'aeteete e puipuia ai kasa leaga ma afi ma fa'alavelave fa'alavelave.
3. I le taimi o le teuina ma le felauaiga, e tatau ona gauai atu e aloese mai le faʻafesoʻotaʻi ma vailaʻau e pei ole oxidants, acids ma alkalis e aloese ai mai faʻalavelave ma faʻalavelave.
Aotelega
I se aotelega, o le ferrous sulfate heptahydrate o se mea faʻapipiʻi faʻapitoa ma e tele mea faʻaoga.
I fale gaosi oloa ma fale suesue, e tatau ona gauai atu i lona tulaga lamatia, ma e tatau ona faia ni faiga talafeagai mo le teuina, felauaiga ma le faʻaogaina e faʻamautinoa ai le saogalemu o le tagata lava ia ma le puipuiga o le siosiomaga.
I le taimi lava e tasi, e tatau ona gauai atu i le faasaoina o punaoa i le faagasologa o le faaaogaina e aloese ai mai otaota ma le filogia.
