Qhov sib txawv tseem ceeb ntawm sodium hexametaphosphate thiab sodium polyphosphate yog tias sodium hexametaphosphate yog ib txoj hlua ntev rau ntawm sodium metaphosphate, whereas sodium polyphosphate yog lub kaus siv lub npe tag nrho cov sodium phosphate units nrog plaub los yog ntau tshaj phosphate. units.
Cov ntsiab lus sodium hexametaphosphate thiab sodium polyphosphate yog hais txog cov tshuaj tau los ntawm sodium phosphate ntsev. Cov no feem ntau yog cov molecules loj nrog cov qauv tshuaj nyuaj.
Sodium Hexametaphosphate yog dab tsi?
Sodium hexametaphosphate yog ib qho ntsev inorganic uas muaj cov tshuaj formula Na6[(PO3) 6]. Kev lag luam, nws feem ntau tshwm sim raws li kev sib xyaw ntawm metaphosphates muaj daim ntawv hexamer. Ntau qhov tseeb, hom kev sib xyaw no tuaj yeem hu ua sodium polymetaphosphate. Cov khoom no tshwm sim raws li cov khoom dawb uas yaj hauv dej.
Daim duab 01: Cov Qauv Tshuaj ntawm Sodium Hexametaphosphate
Lwm lub npe uas peb tuaj yeem siv los sau cov tshuaj no suav nrog Calgon S, glassy sodium, Graham's ntsev, metaphosphoric acid, thiab lwm yam. Cov molar loj ntawm cov tshuaj no yog 611.77 g / mol. Nws zoo nkaus li dawb crystals, thiab nws tsis muaj ntxhiab tsw. Txawm hais tias nws yog dej-soluble, insoluble hauv organic solvents.
Muaj ntau yam kev siv sodium hexametaphosphate, uas suav nrog kev siv nws ua ib qho sequestrant, ua cov khoom noj ntxiv hauv kev lag luam khoom noj, ua dej muag muag, thiab ua tshuaj ntxuav tes. Lwm qhov tseem ceeb ntawm kev siv cov tshuaj no yog siv nws ua ib qho deflocculant hauv kev tsim cov av nplaum-raws li ceramic hais. Ntxiv mus, peb tuaj yeem siv nws ua tus neeg sawv cev rau kev tawg ntawm av nplaum thiab lwm hom av hauv kev ntsuas kev ntxhib los mos.
Cov tshuaj no tuaj yeem npaj tau los ntawm cua sov monosodium orthophosphate rau kev tsim ntawm sodium acid pyrophosphate, uas yog tom qab cua sov kom tau txais cov sodium hexametaphosphate.
Sodium Polyphosphate yog dab tsi?
Sodium polyphosphate yog ib hom sodium phosphate thiab ntsev ntawm sodium ion thiab phosphate. Cov ntsev no yog tsim los ntawm cov cua kub sib tov ntawm NaH2PO4 thiab Na2HPO4. Qhov no induces ib tug condensation cov tshuaj tiv thaiv. Tom qab ntawd, qhov tshwj xeeb polyphosphate yog tsim nyob ntawm cov ntsiab lus ntawm cov cua sov thiab kev sib tsoo.
Ib qho piv txwv ntawm sodium polyphosphates yog Glassy Graham ntsev. Nws yog cov tshuaj polyphosphate linear uas muaj cov tshuaj formula NaO(NaPO3)Na2 Muaj qee cov crystalline siab molecular hnyav polyphosphates, suav nrog Kurrol cov ntsev thiab Maddrell's ntsev.
Qhov txawv ntawm Sodium Hexametaphosphate thiab Sodium Polyphosphate yog dab tsi?
Sodium hexametaphosphate thiab sodium polyphosphate yog cov khoom tau los ntawm sodium phosphate ntsev. Cov no feem ntau yog cov molecules loj nrog cov qauv tshuaj nyuaj. Qhov sib txawv tseem ceeb ntawm sodium hexametaphosphate thiab sodium polyphosphate yog tias sodium hexametaphosphate yog ib txoj hlua ntev rau ntawm sodium metaphosphate, hos sodium polyphosphate yog lub kaus siv lub npe tag nrho cov sodium phosphate units nrog plaub lossis ntau dua phosphate units.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm sodium hexametaphosphate thiab sodium polyphosphate hauv daim ntawv tabular rau ib sab sib piv.
Summary – Sodium Hexametaphosphate vs Sodium Polyphosphate
Sodium hexametaphosphate yog ib qho ntsev inorganic uas muaj cov tshuaj formula Na6[(PO3) 6]. Sodium polyphosphate yog ib hom sodium phosphate thiab ntsev ntawm sodium ion thiab phosphate. Qhov sib txawv tseem ceeb ntawm sodium hexametaphosphate thiab sodium polyphosphate yog tias sodium hexametaphosphate yog ib txoj hlua ntev rau ntawm sodium metaphosphate, hos sodium polyphosphate yog lub kaus siv lub npe tag nrho cov sodium phosphate units nrog plaub lossis ntau dua phosphate units.
