Cov ntawv thov ntawm sodium fluoride

Sodium fluoride; Naf; sf; Inorganic fluoride, nws yog tsis muaj muaj xim muaj xim, yog cov hmoov dawb, yog rau Tegragonal system, yog qhov zoo Hexahedral lossis Octahedral muaju. Nws yog me ntsis soluble hauv cawv, soluble hauv dej. Aqueous daws yog acidic. Nws yaj nyob rau hauv hydroflluoric acid los ua cov sodium hydrogen fluoride.
1. Sodium fluoride yog siv los ua inlaid steel rau cov neeg kho tshuab hniav thiab PLANER txhawm rau txhim kho Weld lub zog. Thib ob, nws yog siv los ua cov tshuaj txuag ntoo, fungicides hauv cov tshuaj tua brewing, yuav tsum muaj cov tshuaj tua kab mob, yuav tsum muaj cov tshuaj tua kab mob npaws (cov tshuaj flux, cov tshuaj fluorine rau cov dej haus. Kuj tseem siv rau kev tsim lwm cov tshuaj fluoride thiab cov ntaub nplaum mos, cov nplaum tshuaj fluoride, ua cov nplaum, kuj siv hauv cov ntawv thiab metallgical kev lag luam. Hauv kev tsim cov tshuaj fluorine, nws yog siv rau kev tshem tawm cov kab ntawm cov tshuaj fluoride hydrogen. Tsis tas li ntawd, nws tseem siv rau hauv Enamels thiab Tshuaj Ntsuam Kev Lag Luam.
2. So cov tshuaj fluoride yog siv los ua tshuaj tua kab mob, tshuaj tua kab, tshuaj tiv thaiv, kev tsim khoom, ua kom cov tshuaj fluoride thiab lwm yam.
3. Siv rau kev txiav txim siab ntawm scandium hauv microanalysis, siv los ua phos phos digetric, siv ua cov tshuaj pleev xim duab, cov tshuaj tiv thaiv hlau thiab cov hlau.
4. Raws li cov khoom noj khoom haus. Raws li cov cai lij choj suav rau ntsev, qhov siab tshaj plaws yog 0.1g / kg.
5. Nws yog siv los ua cov tshuaj txuag ntoo, tshuaj tua kab, cov khoom siv ua kom huv si, thiab siv rau hauv kev ua kom haus cov dej, thiab siv rau kev lag luam thiab tawv nqaij ua tanning kev lag luam, Rau smelting thiab refining ntawm lub teeb hlau, thiab kev tiv thaiv txheej, thiab kev tiv thaiv kab hlau, rau cov nplaum corrosion, thiab kev tsim cov hlau boiling.
6. Sodium fluoride yog siv los ua cov tshuaj ntsuas kom ruaj khov, ua kom zoo nkauj ua kom muaj kev lag luam hauv xov tooj phosphate, txhim kho cov kev ua tau zoo ntawm phosphote txheej. Aluminium thiab nws cov khoom siv phosphate tuaj yeem kaw cov catalytic al3 + ntawm kev phom sij zoo, thiab ua rau phosphatly. Nws yog siv los ua cov tshuaj txuag ntoo, cov tshuaj tua tsiaj, cov fungicides hauv fluin, alkaline zinc exteritives thiab enamel, ntawv thiab lwm daim ntawv.
