I-Ferrous Sulphate Heptahydrate

Isingeniso esifushane：

I-ferrous sulfate heptahydrate, eyaziwa kakhulu ngokuthi i-green alum, iyinhlanganisela engaphili enefomula i-FeSO4·7H2O. Isetshenziswa kakhulu ekwenziweni kosawoti wensimbi, uyinki, i-magnetic iron oxide, i-ejenti yokuhlanza amanzi, isibulala-magciwane, i-catalyst yensimbi; Isetshenziswa njengodayi wamalahle, i-ejenti yokuthamba, i-ejenti yokumhlopheza, i-preservative yokhuni kanye ne-compound fertilizer additive, kanye nokucubungula i-ferrous sulfate monohydrate. Izakhiwo, ukusetshenziswa, ukulungiswa kanye nokuphepha kwe-ferrous sulfate heptahydrate kwethulwa kuleli phepha.

Imvelo

I-ferrous sulfate heptahydrate iyikristalu eluhlaza okwesibhakabhaka enesistimu yekristalu eshintshanayo enhle kanye nesakhiwo esijwayelekile esinama-hexagonal esihlanganisiwe.

I-ferrous sulfate heptahydrate kulula ukuyilahla emoyeni bese iba yi-anhydrous ferrous sulfate, enokuncishiswa okukhulu kanye nokubola.

Isixazululo sayo samanzi sine-asidi ngoba siyabola emanzini ukuze sikhiqize i-sulfuric acid kanye nama-ion e-ferrous.

I-ferrous sulfate heptahydrate inobuningi obungu-1.897g/cm3, iphuzu lokuncibilika elingu-64 ° C kanye nephuzu lokubila elingu-300 ° C.

Ukuqina kwayo ekushiseni akukuhle, futhi kulula ukubola emazingeni okushisa aphezulu ukuze kukhiqizwe amagesi ayingozi njenge-sulfur dioxide kanye ne-sulfur trioxide.

Isicelo

I-ferrous sulfate heptahydrate isetshenziswa kabanzi embonini.

Okokuqala, iwumthombo obalulekile wensimbi, ongasetshenziswa ukulungisa ezinye izinhlanganisela zensimbi, njenge-ferrous oxide, i-ferrous hydroxide, i-ferrous chloride, njll.

Okwesibili, ingasetshenziswa ukulungisa amakhemikhali afana namabhethri, amadayi, ama-catalyst, kanye nezibulala-zinambuzane.

Ngaphezu kwalokho, ingasetshenziswa nasekuphatheni amanzi amdaka, ekususeni i-sulfurization, ekulungiseleleni umanyolo we-phosphate nezinye izici.

Ukubaluleka kwe-ferrous sulfate heptahydrate kusobala, futhi kunezindlela eziningi zokusebenzisa ekukhiqizweni kwezimboni.

Indlela yokulungiselela

Kunezindlela eziningi zokulungiselela i-ferrous sulfate heptahydrate, futhi izindlela ezivamile yilezi ezilandelayo:

1. Ukulungiswa kwe-sulfuric acid kanye ne-ferrous powder.

2. Ukulungiswa kwe-sulfuric acid kanye nokusabela kwe-ingot yensimbi.

3. Ukulungiswa kwe-sulfuric acid kanye ne-ammonia yensimbi.

Kufanele kuqashelwe ukuthi izimo zokusabela kufanele zilawulwe ngokuqinile ngesikhathi senqubo yokulungiselela ukuze kugwenywe amagesi ayingozi kanye nokulahlekelwa okungadingekile.

Ukuphepha

I-ferrous sulfate heptahydrate inengozi ethile, kudingeka unake amaphuzu alandelayo:

1. I-ferrous sulfate heptahydrate iyinhlanganisela enobuthi futhi akufanele ithintwe ngqo. Ukuphefumula, ukugwinya kanye nokuxhumana nesikhumba namehlo kufanele kugwenywe.

2. Ekulungiseleleni nasekusebenziseni i-ferrous sulfate heptahydrate, kufanele kuqashelwe ukuvimbela amagesi ayingozi kanye nezingozi zomlilo nokuqhuma.

3. Ngesikhathi sokugcina nokuthuthwa, kufanele kuqashelwe ukugwema ukuthintana namakhemikhali anjenge-oxidants, ama-acids nama-alkali ukuze kugwenywe ukusabela kanye nezingozi.

Isifinyezo

Ngamafuphi, i-ferrous sulfate heptahydrate iyinhlanganisela ebalulekile ye-inorganic futhi inezinhlobo eziningi zokusetshenziswa.

Ezimbonini zokukhiqiza kanye nasezilabhorethri, kufanele kuqashelwe ingozi yayo, futhi kufanele kuthathwe izinyathelo ezifanele zokugcina, ukuthuthwa kanye nokusetshenziswa ukuqinisekisa ukuphepha komuntu siqu kanye nokuvikelwa kwemvelo.

Ngesikhathi esifanayo, kufanele kuqashelwe ukonga izinsiza enkambisweni yokusebenzisa ukuze kugwenywe imfucuza nokungcola.
