Funda malunga nokudityaniswa kwayo, ukusebenza kweekhemikhali, kunye nendima ebalulekileyo eyidlalayo kwiinkalo ezahlukeneyo. Ukuqonda intsimbi 2 sulfide ibalulekile kwiingcali kwikhemistri, kwisayensi yezixhobo, nakwiindawo ezinxulumeneyo.

IiPropati zePhysical and Chemical of Iron 2 Sulfidi

Imbonakalo kunye neSakhiwo

Iron 2 sulfide ngokwesiqhelo ibonakala njengengwevu emnyama ukuya kwikristale emnyama eqinileyo. Ubume bayo be-crystal buguquguqukayo, kuxhomekeke kwiimeko apho zenziwe khona. Iifom eziqhelekileyo ziquka i-troilite (ifom ye-mineral hexagonal) kunye ne-mackinawite (ifom ye-tetragonal mineral). Ulwakhiwo oluchanekileyo luchaphazela kakhulu ukusebenza kwakhona kunye nezicelo.

Iimpendulo zeMichiza

Iron 2 sulfide isabela ngokukhawuleza kunye neeasidi, ikhuphe ihydrogen sulfide (H₂S), irhasi enetyhefu kakhulu nenokutsha. Le ndlela yokusabela isetyenziswa rhoqo kwilabhoratri yokudityaniswa kwe-H₂S. Kwakhona kungena kwi-oxidation phambi kwe-oxygen, enokuthi yenze i-iron oxides kunye ne-sulfates. Le nkqubo ye-oxidation ibalulekile ekuqondeni ukuziphatha kwayo kwiimeko ezahlukeneyo zokusingqongileyo.

Usetyenziso lwe Iron 2 Sulfidi

Isinyithi

Kwishishini lesinyithi, intsimbi 2 sulfide idlala indima ebalulekileyo njengesandulela kwimveliso yentsimbi kunye nentsimbi. Ubukho bayo kwi-iron ores bunokuchaphazela inkqubo yokunyibilikisa kwaye ifuna ukuqwalaselwa ngenyameko ngexesha lentsimbi. Ukususwa kwesulfure kwintsimbi kuyinyathelo elibalulekileyo lokufikelela kwintsimbi ephezulu.

Ishishini lemichiza

Iron 2 sulfide isebenza njengomthombo wesulfure kwishishini lemichiza. Ingasetyenziselwa ukuveliswa kwezixhobo ezahlukeneyo ezinesulfure, kuquka i-asidi ye-sulfuric (ngenkqubo yeClaus). Ukusebenza kokutsalwa kwesulfure ukusuka intsimbi 2 sulfide ngumba ophambili kuqoqosho lwezi nkqubo.

Ukusetyenziswa kokusingqongileyo

Ukuphinda kusebenze kwe intsimbi 2 sulfide ngesinyithi esinzima senza ukuba ibe licandelo elinokubakho kwizicwangciso zokulungiswa kokusingqongileyo. Ingasetyenziselwa ukususa izinto ezingcolisa isinyithi esinzima kumanzi amdaka ngokusebenzisa i-adsorption okanye imvula. Uphando luyaqhubeka ukuhlola ukusebenza kweendlela ezahlukeneyo intsimbi 2 sulfide kwezi zicelo. Ukusebenza kakuhle kunye nokuphumelela kweendleko zizinto ezibalulekileyo ezibonisa ukwamkelwa kwayo ngokubanzi.

ImiGaqo yoKhuseleko xa Uphethe Iron 2 Sulfidi

Iron 2 sulfide iveza iingozi ezithile zokhuseleko, ikakhulu ngenxa yokusabela kwayo ngeeasidi kunye nokubanakho kwayo kwi-oxidation. Ukuqhagamshelana ngokuthe ngqo nama-acids kunokukhokelela ekukhululweni kwegesi enetyhefu kunye nenokutsha ye-hydrogen sulfide, efuna ukungena komoya okufanelekileyo kunye nezixhobo zokukhusela zomntu (PPE). Ngaphezu koko, ukuvezwa kwesohlwayo intsimbi 2 sulfide uthuli lunokubangela ukucaphuka kokuphefumula. Ngoko ke, iinkqubo ezifanelekileyo zokuphatha, kubandakanywa nokusetyenziswa kwe-respirators kunye neiglavu, ziyimfuneko.

Udibaniso lwe Iron 2 Sulfidi

Iron 2 sulfide inokwenziwa ngeendlela ezahlukeneyo, kubandakanywa ukuphendula ngokuthe ngqo kwentsimbi kunye nesulfure phantsi kweemeko ezilawulwayo. Ezinye iindlela zibandakanya ukusabela kweetyuwa zentsimbi kunye nemithombo yesulfide kwisinyibiliko. Ubunyulu kunye nesakhiwo se-crystalline sesiphumo intsimbi 2 sulfide inokwahluka kakhulu ngokuxhomekeke kwindlela ekhethiweyo kunye neeparamitha zokusabela. Indlela echanekileyo yokudibanisa isoloko ilungelelaniswe nesicelo esithile.

Ukuthelekiswa kweentlobo ezahlukeneyo ze-Iron Sulfidi

Kukho iindlela ezahlukeneyo ze-iron sulfide, ebonisa iipropati ezahlukeneyo kunye nokusetyenziswa. Le theyibhile ingezantsi inika uthelekiso olufutshane lwezinye iimpawu eziphambili.

Qaphela: Olu lwazi lulungiselelwe iinjongo zemfundo kuphela. Ngalo lonke ixesha ujongana namaphepha edatha yokhuseleko (SDS) kunye nemigaqo efanelekileyo ngaphambi kokuba uphathwe intsimbi 2 sulfide okanye ezinye iikhemikhali.
