Sodium Fluoride

Sodium fluoride,ndi mtundu wa pawiri, mankhwala chilinganizo ndi NaF, makamaka ntchito ❖ kuyanika makampani monga phosphating accelerator, mankhwala ophera tizilombo, kusindikiza zipangizo, zotetezera ndi zina.

Katundu Wathupi:Kachulukidwe wachibale ndi 2.558 (41/4 ​​° C), malo osungunuka ndi 993 ° C, ndipo malo otentha ndi 1695 ° C [1].(Kachulukidwe kachulukidwe 2.79, malo osungunuka 992 ° C, malo otentha 1704 ° C [3]) Amasungunuka m'madzi (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100gchemicalbook), sungunuka mu hydrofluoric acid, ndi osasungunuka mu ethanol.Njira yamadzimadzi ndi yamchere (pH = 7.4).Poizoni (kuwonongeka kwa dongosolo lamanjenje), LD50180mg/kg (mbewa, pakamwa), 5-10 magalamu mpaka kufa.Katundu: wopanda mtundu kapena woyera crystalline ufa, kapena kiyubiki makhiristo, makhiristo zabwino, popanda fungo.

Chemical katundu:kristalo wonyezimira wopanda mtundu kapena ufa woyera, tetragonal system, wokhala ndi makhiristo okhazikika a hexahedral kapena octahedral.Kusungunuka pang'ono mu mowa;Kusungunuka m'madzi, njira yamadzimadzi ndi acidic, sungunuka mu hydrofluoric acid kupanga sodium hydrogen fluoride.

Ntchito:

1. Ikhoza kugwiritsidwa ntchito ngati chitsulo cha carbon-high-carbon, monga air-proof agent wa zitsulo zowira, aluminiyamu electrolytic kapena electrolytic refined melting agent, madzi opangira mapepala, zosungira matabwa (ndi sodium fluoride ndi nitrate kapena diitol phenol For anti -kuwonongeka kwa zinthu zoyambira), gwiritsani ntchito zida (madzi akumwa, mankhwala otsukira mano, etc.), zowumitsa, mankhwala ophera tizilombo, zotetezera, etc.

2. Amagwiritsidwa ntchito pofuna kuteteza mano a mano ndi oral caries chifukwa cha kusowa kwa fluoride m'madzi m'madzi m'madzi;

3. Mankhwala ang'onoang'ono amagwiritsidwa ntchito makamaka kwa osteoporosis ndi matenda a paget bone;

4. Angagwiritsidwe ntchito ngati zopangira kapena fluoride kuyamwa fluoride ena kapena fluoride;

5. Angagwiritsidwe ntchito ngati UF3 adsorbent mu kuwala zitsulo fluorine mankhwala mchere wothandizira, smelting refiners, ndi mafakitale nyukiliya;

6. Kuchapira njira yachitsulo ndi zitsulo zina, welded wothandizira ndi welds;

7. Ceramics, magalasi ndi enamel amasungunuka ndi shading agents, khungu laiwisi ndi epidermal treatment agents of the toni industry;

8. Pangani olimbikitsa phosphate pamankhwala apamwamba achitsulo chakuda kuti akhazikitse njira ya phosphorurative ndikuwongolera magwiridwe antchito a phosphorous;

9. Monga chowonjezera pakupanga zida zosindikizira ndi ma brake pads, zimathandizira pakuwonjezera kukana kuvala;

10. Monga zowonjezera mu konkire, onjezerani kukana kwa dzimbiri kwa konkire.

Kusamalitsa:

1. Gwiritsani ntchito sodium fluoride mosamalitsa kuwongolera kuchuluka kwa fluorine tsiku lililonse kuteteza kupanga poizoni wa fluoride;

2. Madzi a sodium fluoride kapena gel osakaniza ayenera kuikidwa mu chidebe chapulasitiki;

3. Odwala, amayi apakati, amayi oyamwitsa, kufewa kwa fupa ndi kulephera kwaimpso m'madera ambiri a fluoride ndizoletsedwa.
