Cov ntawv thov ntawm Sodium fluoride

Sodium fluoride; NaF; SF; Inorganic Fluoride, Nws yog cov siv lead ua tsis muaj xim lossis hmoov dawb ci, koom nrog tetragonal system, yog cov siv lead ua hexahedral lossis octahedral zoo. Nws yaj me ntsis hauv cawv, yaj hauv dej. Cov kua dej yog acidic. Nws yaj hauv hydrofluoric acid los ua sodium hydrogen fluoride.
1. Sodium fluoride feem ntau yog siv los ua cov hlau Inlaid rau cov hniav thiab planer kom txhim kho lub zog vuam. Qhov thib ob, nws yog siv los ua cov tshuaj tiv thaiv ntoo, fungicides hauv kev lag luam brewing, tshuaj tua kab ua liaj ua teb (yuav tsum tau kis kab mob xiav), tshuaj tiv thaiv kev kho mob, vuam flux, fluorine tus neeg sawv cev rau dej haus. Kuj tseem siv rau kev tsim lwm yam fluoride thiab casein kua nplaum, sodium fluoride tshuaj txhuam hniav, ua cov nplaum, kuj siv rau hauv kev lag luam ntawv thiab hlau. Hauv kev tsim cov elemental fluorine, nws yog siv los tshem tawm cov hydrogen fluoride me me. Tsis tas li ntawd, nws kuj tseem siv rau hauv kev lag luam enamels thiab tshuaj.
2. Sodium fluoride yog siv los ua cov tshuaj tua kab mob, cov tshuaj preservatives, cov tshuaj tua kab, kuj siv rau hauv enamel, kev khaws cia ntoo, tshuaj, metallurgy, kev tsim cov fluorides thiab lwm yam.
3. Siv rau kev txiav txim siab ntawm scandium hauv microanalysis, kev txiav txim siab ntawm phosphorus hauv photoelectric colorimetric tsom xam, siv ua reagent, cov neeg sawv cev masking, preservatives ntawm hlau thiab hlau.
4. Ua cov khoom noj khoom haus ntxiv. Raws li cov cai lij choj Suav rau ntsev, qhov siab tshaj plaws siv yog 0.1g / kg.
5. Nws yog siv ua cov tshuaj tiv thaiv ntoo, tshuaj tiv thaiv tshuaj, cov kua nplaum vuam thiab siv rau hauv kev lag luam ntawv, cov khoom lag luam ntawm lub tuam txhab no yog cov tshuaj txhuam hniav qib tshwj xeeb, kuj tseem siv tau ua tus neeg sawv cev ntxuav dej haus, thiab siv rau kev ua tawv nqaij thiab tawv nqaij hauv kev lag luam tanning, rau kev smelting thiab refining ntawm cov hlau sib dua, thiab txheej tiv thaiv ntawm cov hlau sib dua, rau kev xeb nplaum, thiab tsim cov hlau npau.
6. Sodium fluoride siv ua phosphate accelerator hauv kev lag luam txheej, ua rau phosphating kua ruaj khov, phosphate refinement, txhim kho kev ua haujlwm ntawm phosphate txheej. Aluminium thiab nws cov alloys phosphate tuaj yeem kaw cov catalytic tsis zoo Al3 + uas muaj kev phom sij loj, thiab ua rau phosphating du. Nws yog siv ua cov ntoo preservatives, cov tshuaj tua kab ua liaj ua teb, fungicides hauv kev lag luam brewing, tshuaj preservatives, welding flux, alkaline zincate zinc additives thiab enamel, ntawv thiab lwm yam.
