Kev Taw Qhia
Sodium monofluorophosphate (SMFP luv luv) yog cov hmoov dawb uas muaj qhov melting point ntawm li 626 ℃. Nws yooj yim soluble hauv dej thiab muaj zog nqus dej noo. Nws solubility hauv dej ntawm 25 ℃ yog 42%. Yog tsis muaj qhov cuam tshuam corrosion ntawm Chemicalbook, tus nqi pH ntawm 2% aqueous kua yog 6.5 ~ 8.0, thiab cov kua aqueous maj mam hydrolyzes thaum npau, uas tuaj yeem ua rau txo qis ntawm cov fluorine khi thiab nce ntawm cov fluorine dawb, yog li qhov huv si raug txo qis.

Kev Siv
Es tsis txhob siv sodium fluoride, nws tuaj yeem siv ua tus neeg sawv cev tiv thaiv kab mob caries, tus neeg ua kom cov hniav tsis hnov mob, tus neeg ntxuav cov hlau, tus neeg ua kua dej, thiab lub khob tshwj xeeb hauv cov tshuaj txhuam hniav.
Ua ib yam tshuaj tua kab mob thiab ua kom cov hniav tsis txhob lwj, feem ntau nws suav txog 0.7% ~ 0.76% ntawm cov tshuaj txhuam hniav. Tam sim no, sodium fluoride tau hloov pauv los ntawm txawv teb chaws, thiab nws tau txais txiaj ntsig zoo dua hauv kev sib tw nrog cov tshuaj fluoride uas muaj zog. Nws kuj siv rau kev ntxuav cov hlau thiab ua cov kua dej, thiab ua cov iav tshwj xeeb. Nws kuj siv ua tshuaj tua kab mob thiab tshuaj tua kab mob.
