He kupu whakataki poto：
Ko te ferrous sulfate heptahydrate, e mōhiotia whānuitia ana ko te green alum, he matū kore-waro me te tātai FeSO4·7H2O. E whakamahia ana i roto i te hanga tote rino, waituhi, waikura rino aukume, kaihoko horoi wai, kaiwhakamate huakita, whakakorikori rino; E whakamahia ana hei tae waro, kaihoko tanning, kaihoko whakama, tiaki rakau me te tāpiri tongi matū, me te tukatuka ferrous sulfate monohydrate. Ka whakaurua ngā āhuatanga, ngā tono, te whakarite me te haumaru o te ferrous sulfate heptahydrate ki roto i tēnei pepa.
Taiao
He tioata kikorangi te konukōhate heptahydrate me te pūnaha tioata tauutuutu pai, me te hanganga tapaono-piripiri noa.
He ngāwari te ngaro o te wai karaihe i te rangi i roto i te heptahydrate ferrous sulfate, ka huri hei ferrous sulfate anhydrous, he kaha te whakaiti me te waikura.
He waikawa tōna wairewa nā te mea ka pirau i roto i te wai ka puta he waikawa whanariki me ngā katote ferrous.
Ko te mātotoru o te konupūmā ferrous heptahydrate he 1.897g/cm3, ko te ira rewa he 64°C, ā, ko te ira koropupū he 300°C.
He ngoikore tōna pumau wera, ā, he ngāwari te pirau i ngā pāmahana tiketike ka puta he hau kino pērā i te hauhā whanariki me te hauhā whanariki toru.
Tono
E whakamahia whānuitia ana te ferrous sulfate heptahydrate i roto i ngā ahumahi.
Tuatahi, he puna nui tēnei mō te rino, ka taea te whakamahi hei hanga i ētahi atu matū rino, pērā i te waikura ferrous, te hauwaiwai ferrous, te pūhaumāota ferrous, me ētahi atu.
Tuarua, ka taea te whakamahi hei hanga matū pēnei i ngā pākahiko, ngā tae, ngā whakakorikori, me ngā patupatu.
Hei tāpiri, ka taea hoki te whakamahi i roto i te maimoatanga wai para, te tango i te whanariki, te whakarite tongi phosphate me ētahi atu āhuatanga.
He mea mārama te hiranga o te ferrous sulfate heptahydrate, ā, he whānuitia hoki ōna whakamahinga i roto i te hanga ahumahi.
Tikanga whakarite
He maha ngā tikanga mō te whakarite i te ferrous sulfate heptahydrate, ā, ko ngā tikanga noa e whai ake nei:
1. Te whakarite i te waikawa whanariki me te paura rino.
2. Te whakarite i te waikawa whanariki me te tauhohenga o te ingota ferrous.
3. Te whakarite i te waikawa whanariki me te haukini rino.
Me mōhio kia tino whakahaerehia ngā āhuatanga o te tauhohenga i te wā o te tukanga whakarite kia kore ai e puta he hau kino me ngā ngaronga koretake.
Haumarutanga
He mōrearea te heptahydrate konukōre ferrous, me aro ki ngā āhuatanga e whai ake nei:
1. He matū paitini te ferrous sulfate heptahydrate, ā, kaua e pā tika atu. Me karo te manawa, te horomitanga me te pa ki te kiri me ngā kanohi.
2. I te wā e whakarite ana, e whakamahi ana hoki i te ferrous sulfate heptahydrate, me tūpato kia kore ai e pā mai ngā hau kino me ngā tūponotanga ahi me te pahūtanga.
3. I te wā e rongoa ana, e kawe ana hoki, me tūpato kia kaua e pā ki ngā matū pēnei i ngā waikura, ngā waikawa me ngā kawakore hei karo i ngā tauhohenga me ngā aituā.
Whakarāpopototanga
Hei whakarāpopototanga, he matū kore-waro nui te ferrous sulfate heptahydrate, ā, he whānuitia ōna whakamahinga.
I roto i ngā mahi whakaputa ahumahi me ngā taiwhanga, me aro ki tōna mōrearea, ā, me mahi i ngā mahi tika mō te rokiroki, te kawe me te whakamahinga 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 whakamahinga kia kore ai e moumou me te poke.
