Sodium fluoride, the atomic blueprint NaBF4, white or achromatic cellophane right-angle prism, the edgeless tip. Adhesive finishing abettor for bolt press and dyeing, non-ferrous metals ( abnormally aluminum ) metal atom admeasurement abridgement abettor and adorning flux, aluminum and magnesium admixture casting beach agent. Fluoride boric acerbic sodium carbonate adjustment aboriginal in the acknowledgment kettle by boric acerbic and hydrofluoric acerbic was able by the acknowledgment of fluorine boric acid, and afresh accord the abatement tank, active and cooling down, boring abacus sodium carbonate, ascendancy of the acknowledgment temperature of not added than 35 DEG c.. Pay assimilation to adept the agriculture speed, to anticipate the aqueous from gas escape bulk is too ample and the overflow tank. And to the aqueous was Ph3～ 4, 0.5h again. Afresh by evaporating, cooling crystallization, centrifugal separation, washing, drying, able sodium fluoride products. The 2HBF4+Na2CO3→ 2NaBF4 +CO2↑+H2O; aswell by boric acerbic fluoride and sodium fluoride or sodium hydroxide able with reaction; aswell accessible three boron fluoride and sodium fluoride able by absolute reaction.
Sodium fluoride adhesive finishing abettor for bolt press and dyeing, non-ferrous metals ( abnormally aluminum ) metal atom admeasurement abridgement abettor and adorning flux, aluminum and magnesium admixture casting beach agent. As the continued cilia bolt with 2D ( dimethylol two hydroxy ethylene urea adhesive finishing agitator ); aswell acclimated as reagents for actinic analysis, electrochemical antioxidant, non-ferrous metals, such as ablution flux. This artefact is nonflammable, with able bane resistance, able irritation, causing burns to animal body. Inhalation, articulate or derma assimilation of adverse to the body. To the eyes, skin, close membranes and respiratory amplitude accept a able aesthetic effect. Inhalation can could cause throat and bronchial spasm, edema, inflammation, actinic pneumonia, pulmonary edema and death. Toxic appearance has afire feeling, cough, wheezing, conciseness of breath, laryngitis, headache, abhorrence and vomiting. Stored in a cool, blast of the treasury. Away from fire, calefaction source. Keep alembic deeply closed. With the bases stored separately, abstain bond reservoir. Storage areas should be able with emergency analysis accessories for arising and acceptable apartment materials.
