He kupu whakataki poto：
Ko te ferrous sulfate heptahydrate, e mohiotia ana he kowau kaakaariki, he puhui pararopi me te tikanga FeSO4·7H2O.Te nuinga whakamahia i roto i te hanga o te tote rino, mangumangu, waikura rino autō, māngai pure wai, waipatu, whakakōkī rino;Ka whakamahia hei waikano waro, hei kaihoko tanning, hei kai whakapoipoi, hei whakamarumaru rakau me te taapiri tongi, me te tukatuka ferrous sulfate monohydrate. Ko nga taonga, nga tono, te whakarite me te haumaru o te heptahydrate ferrous sulfate kua whakauruhia ki tenei pepa.
Taiao
Ko te Ferrous sulfate heptahydrate he karaihe kikorangi me te punaha karaihe tauutuutu pai me te hanganga hexagonal angamaheni kati-Kikī.
Ko te heptahydrate ferrous sulfate he ngawari ki te ngaro i te wai karaihe i te rangi ka huri hei ferrous sulfate anhydrous, he kaha te whakaheke me te waikura.
He waikawa te wairewa wai na te mea ka pirau i roto i te wai hei whakaputa i te waikawa pungatara me nga katote ferrous.
Ko te ferrous sulfate heptahydrate he 1.897g/cm3 te kiato, he rewa te 64 ° C me te ira koropuha 300 ° C.
He kino te noho o te waiariki, he ngawari te pirau i te wera nui hei whakaputa i nga hau kino penei i te sulfur dioxide me te sulfur trioxide.
Taupānga
Ka whakamahia nuitia te heptahydrate ferrous sulfate i roto i te umanga.
Tuatahi, he puna nui o te rino, ka taea te whakamahi ki te whakarite i etahi atu puhui rino, penei i te ferrous oxide, ferrous hydroxide, ferrous chloride, etc.
Tuarua, ka taea te whakamahi ki te whakarite matū penei i te pākahiko, waikano, whakakōkī, me ngā patukīrea.
I tua atu, ka taea hoki te whakamahi i te maimoatanga wai para, te desulfurization, te whakarite tongi phosphate me etahi atu waahanga.
Ko te hiranga o te heptahydrate ferrous sulfate he tino kitea, a he maha nga tono mo te hanga ahumahi.
Tikanga whakarite
He maha nga tikanga mo te whakarite i te ferrous sulfate heptahydrate, a ko nga tikanga noa e whai ake nei:
1. Te whakarite i te waikawa sulfuric me te paura ferrous.
2. Te whakarite i te waikawa sulfuric me te tauhohenga ingot ferrous.
3. Te whakarite i te waikawa sulfuric me te haukini ferrous.
Me tohu ko nga tikanga tauhohenga me tino whakahaere i te wa o te mahi whakarite kia kore ai nga hau kino me nga mate koretake.
Haumarutanga
Ko te ferrous sulfate heptahydrate he tupono, me aro ki nga waahanga e whai ake nei:
1. Ko te heptahydrate ferrous sulfate he puhui paitini me kaua e pa tika.Me karohia te inhalation, te kai me te pa ki te kiri me nga kanohi.
2. I roto i te whakarite me te whakamahi i te heptahydrate ferrous sulfate, me tupato ki te karo i nga hau kino me nga kino o te ahi me te pahū.
3. I te wa o te rokiroki me te kawe, me aro nui ki te karo i te pa ki nga matū penei i te oxidants, waikawa me te kawakore ki te karo i nga tauhohenga me nga aitua.
Whakarāpopototanga
Hei whakarāpopototanga, he pūhui pararopi nui te ferrous sulfate heptahydrate me te whānuitanga o ngā whakamahinga.
I roto i nga mahi ahumahi me nga taiwhanga, me aro ki tona tupono, me mahi nga tikanga e tika ana mo te rokiroki, te kawe me te whakamahi hei whakarite i te haumaru whaiaro me te tiaki taiao.
I te wa ano, me aro nui ki te penapena rauemi i roto i te tukanga whakamahi hei karo i te ururua me te parahanga.
