Sodium Meta Hexaphosphate
Molecular Luj: 611.77
Cov tsos mob: Cov hmoov dawb crystalline, los yog tsis muaj xim, pob tshab, iav, flaky, los yog lumpy khoom; tsw tsw.
Solubility: Soluble nyob rau hauv dej heev (solubility ntawm 20℃yog kwv yees li 973 g / L), tab sis cov dissolution tus nqi kuj qeeb; insoluble hauv cov kuab tshuaj organic xws li ethanol thiab diethyl ether; Aqueous daws yog qaug zog acidic (pH 5.5-6.5).
Bitop Bihope Qingdao Mining Co., Ltd. yog ib qho ntawm feem txhim khu kev qha manufacturers thiab lwm tus neeg ntawm sodium meta hexaphosphate nyob rau hauv Suav teb, kuj txhawb kev pab customized nrog luv nqi. Yog hais tias koj yuav mus yuav siab heev sodium meta hexaphosphate ua nyob rau hauv Suav teb, txais tos kom tau txais pricelist thiab dawb qauv los ntawm peb lub hoobkas.
Sodium Hexametaphosphate
Molecular Formula:(NPO 3) 6
Molecular Luj: 611.77
Qhov tsos:Dawb crystalline hmoov, los yog tsis muaj xim, pob tshab, iav, flaky, los yog lumpy khoom; tsw tsw.
Solubility:Soluble nyob rau hauv dej heev (solubility ntawm 20℃yog kwv yees li 973 g / L), tab sis tus nqi dissolution kuj qeeb; insoluble hauv cov kuab tshuaj organic xws li ethanol thiab diethyl ether; Aqueous daws yog qaug zog acidic (pH 5.5-6.5).
Hygroscopicity thiab Stability: Exhibits extremely strong hygroscopicity; when exposed to air, it readily deliquesces and cakes, gradually transforming into a viscous, gel-like substance. Its chemical stability is moderate; it undergoes facile hydrolysis in the presence of warm water, acids, or bases, ultimately yielding orthophosphates. It decomposes at high temperatures (>600 degree).
Cov khoom tseem ceeb tshuaj
Strong Chelating Peev Xwm:Cov ntaub ntawv ruaj khov, dej-soluble complexes nrog hlau ions xws li calcium, magnesium, hlau, thiab manganese; ua hauj lwm zoo li dej softener thiab hlau ion sequestering tus neeg sawv cev.
Dispersing / Anti-Flocculating Peev Xwm:Inhibits lub crystallization thiab nag los ntawm calcium thiab magnesium ntsev, disperses cov khoom, thiab tiv thaiv agglomeration.
Buffering Peev Xwm:Stabilizes pH ntawm lub cev thiab txo cov kev hloov pauv hauv acidity thiab alkalinity.

Kev nyab xeeb, Cia, thiab thauj
Kev nyab xeeb:Tsawg toxicity (Qhov ncauj LD₅₀ hauv nas: kwv yees li . 4000 mg/kg); irritates daim tawv nqaij, qhov muag, thiab ua pa; tsis txhob nqus plua plav; Khoom noj khoom haus qib thiab qib Industrial khoom yuav tsum tau muab cais nruj me ntsis thiab tsis txhob sib xyaw.
Cia:Khaws rau hauv qhov chaw txias, qhuav; khaws cov thawv ntim kom nruj kom tsis txhob muaj dej nkag; tiv thaiv los ntawm lub teeb; kom deb ntawm cov kua qaub thiab qhov chaw ntub dej; siv kev ntsuas los tiv thaiv caking thiab hydrolysis-induced degradation.
Kev thauj mus los:Kev thauj mus los raws li kev siv tshuaj lom neeg; tiv thaiv los ntawm nag, ncaj qha tshav ntuj, thiab noo noo; co- thauj nrog cov kua qaub los yog muaj zog oxidizing cov neeg ua haujlwm raug txwv nruj heev.
Cia:Khaws rau hauv qhov chaw txias, qhuav, zoo- qhov cua; xyuas kom cov ntim tseem kaw kom tsis txhob raug huab cua thiab noo noo; niaj hnub tshuaj xyuas cov cim qhia ntawm degradation los yog paug.
