Qhov sib txawv tseem ceeb ntawm potash thiab polyhalite yog tias lo lus potash yog hais txog cov ntxhia ntsev uas muaj cov poov tshuaj, thaum lub sij hawm polyhalite yog hais txog cov hydrated sulfate ntxhia muaj poov tshuaj, calcium thiab magnesium ions.
Potash thiab polyhalite yog cov ntxhia sib xyaw uas peb tuaj yeem pom hauv qhov xwm txheej. Ob qho no yog cov dej-soluble minerals thiab muaj txiaj ntsig zoo li chiv. Lawv muaj ntau txoj kev tsim khoom thiab cov qauv sib txawv thiab.
Puas yog dab tsi?
Potash yog cov dej-soluble ntxhia uas muaj cov poov tshuaj ions. Cov tshuaj no yog tsim nyob rau hauv lub ntiaj teb no nyob rau hauv loj heev npaum li cas los siv raws li ib tug fertilizer. Lub ntuj qhov chaw ntawm potash yog los ntawm ntuj evaporate deposits.
Daim duab 01: Pom ntawm Potash
Ntau zaus, cov ores no tau faus tob rau hauv lub ntiaj teb. Cov ores no yog nplua nuj nyob rau hauv potassium chloride (KCl), sodium chloride (NaCl) thiab lwm yam ntsev nrog rau av nplaum. Peb tuaj yeem tau txais cov pob zeb no los ntawm kev mining. Lwm txoj kev yog kom yaj cov ore ua ntej mining thiab evaporate. Hauv txoj kev evaporation no, peb tuaj yeem txhaj dej kub rau hauv potash, dissolving cov ntxhia. Tom qab ntawd peb tuaj yeem tso nws rau saum npoo. Tom qab ntawd, peb tuaj yeem mloog cov potash ntawm hnub ci evaporation.
Tom qab nitrogen thiab phosphorous, potassium yog qhov xav tau tshaj plaws rau cov qoob loo. Nws yog siv los ua av chiv. Potash tuaj yeem txhim kho cov dej khaws cia hauv av, tuaj yeem ua kom cov qoob loo nce ntxiv, thiab nce cov txiaj ntsig zoo, saj, siv, kev ntxhib los mos ntawm cov txiaj ntsig ntawm cov qoob loo. Tsis tas li ntawd, nws yog ib qho tseem ceeb ua ib qho khoom siv hauv txhuas rov ua dua tshiab, tsim cov poov tshuaj hydroxide, thiab hlau electroplating.
YPolyhalite yog dab tsi?
Polyhalite yog cov dej-soluble ntxhia muaj poov tshuaj, calcium thiab magnesium ions. Nws yog ib qho evaporite ntxhia uas muaj hydrated sulfates. Cov tshuaj formula rau cov ntxhia no tuaj yeem muab tau raws li K2Ca2Mg(SO4) 4·2H2O. Cov zaub mov no muaj cov qauv siv lead ua triclinic, tab sis cov qauv siv lead ua yog tsawg heev. Feem ntau, cov ntxhia no tuaj yeem pom nyob rau hauv loj heev rau daim ntawv fibrous. Feem ntau, nws tsis muaj xim, tab sis tuaj yeem muaj xim liab thiab. Thaum xav txog qhov tshwm sim, nws tshwm sim hauv sedimentary marine evaporates.
Daim duab 02: Pom ntawm Polyhalite
Muaj plaub yam khoom noj tseem ceeb uas peb tuaj yeem tau txais los ntawm cov pob zeb hauv polyhalite: sulfate, sulfate ntawm potash, magnesium sulfate thiab calcium sulfate. Nws yog ib tug nkig ntxhia uas muaj ib tug conchoidal puas. Tsis tas li ntawd, nws muaj vitreous, resinous luster. Cov ntxhia streak ntawm polyhalite yog dawb. Nws yog pob tshab pob zeb.
Qhov txawv ntawm Potash thiab Polyhalite yog dab tsi?
Ob leeg, potash thiab polyhalite, yog cov dej-soluble minerals uas muaj txiaj ntsig zoo li chiv. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm potash thiab polyhalite yog lub sij hawm potash hais txog cov ntxhia ntsev uas muaj cov poov tshuaj, thaum lub sij hawm polyhalite yog hais txog cov hydrated sulfate ntxhia muaj poov tshuaj, calcium thiab magnesium ions. Ntxiv mus, potash yog cov ntxhia uas muaj cov halides yooj yim ntawm cov poov tshuaj thiab sodium nrog cov kab ntsev thiab av nplaum thaum polyhalite yog cov ntxhia uas muaj sulfates ntawm potassium, calcium, thiab magnesium. Thaum xav txog cov txheej txheem ntau lawm, peb tuaj yeem tau txais potash los ntawm kev tsuas, kev sib cais lossis evaporation. Lub caij no, peb tuaj yeem tau txais polyhalite los ntawm mining sedimentary marine evaporates. Qhov pom qhov txawv ntawm potash thiab polyhalite yog lawv cov xim. Potash tshwm nyob rau hauv ib lub cib liab xim, whereas polyhalite tshwm tsis muaj xim nrog liab xim.
Summary – Potash vs Polyhalite
Potash thiab polyhalite yog cov dej-soluble minerals uas muaj txiaj ntsig zoo li chiv. Qhov sib txawv tseem ceeb ntawm potash thiab polyhalite yog tias lo lus potash yog hais txog cov ntxhia ntsev uas muaj cov poov tshuaj, thaum lub sij hawm polyhalite hais txog cov hydrated sulfate ntxhia uas muaj poov tshuaj, calcium thiab magnesium ions.
