Sodium fluoride,imhando yeinorganic compound, iyo kemikari formula ndeyeNaF, inonyanya kushandiswa muindasitiri yekubikira se phosphating accelerator, zvipembenene zvekurima, zvekuisa chisimbiso, zvinochengetedza uye mimwe minda.
Zvinhu Zvenyama:Relative density i2.558 (41/4 ° C), panonyungudika i993 ° C, uye panofashaira i1695 ° C [1].(Relative density 2.79, melting point 992 ° C, boiling point 1704 ° C [3]) Inonyungudika mumvura (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100gchemicalbook), inonyungudika muhydrofluoric acid, uye isingagadzirike mune ethanol.Mushonga wemvura ine alkaline (pH = 7.4).Toxic (kukuvadza kwetsinga system), LD50180mg / kg (mbeva, nemuromo), 5-10 magiramu kusvika pakufa.Zvivakwa: isina ruvara kana kunyange chena crystalline poda, kana cubic crystals, makristasi akanaka, asina kunhuwa.
Chemical properties:isina ruvara inopenya crystal kana chena poda, tetragonal system, ine yakajairwa hexahedral kana octahedral makristasi.Kunyungudika zvishoma mudoro;Soluble mumvura, aqueous solution is acidic, soluble in hydrofluoric acid kuumba sodium hydrogen fluoride.
Application:
1. Inogona kushandiswa seyakakwirira-carbon simbi, yakadai semhepo-proof agent yesimbi inopisa, aluminium electrolytic kana electrolytic yakanatswa yakanyunguduka, kushandiswa kwemvura kwepepa, matanda ekuchengetedza (ine sodium fluoride uye nitrate kana diitol phenol For anti. -kuora kwezvinhu zvepasi), shandisa zvinhu (mvura yekunwa, mazino, etc.), sterilizers, insecticides, preservatives, nezvimwewo.
2. Inoshandiswa kudzivirira dental caries uye oral caries mukushayikwa kwefluoride mumvura mumvura mumvura;
3. Mishonga miduku inonyanya kushandiswa kune osteoporosis uye paget bone chirwere;
4. Inogona kushandiswa seyakabikwa kana fluoride inonyudza yeimwe fluoride kana fluoride;
5. Inogona kushandiswa seUF3 adsorbent muchiedza chesimbi fluorine salt treatment agents, smelting refiners, uye maindasitiri enyukireya;
6. Washing solution yesimbi nedzimwe simbi, welded agents uye welds;
7. Ceramics, girazi uye enamel inonyunguduka uye shading agents, ganda rakasviba uye epidermal treatment agents of the toni industry;
8. Ita phosphate vanokurudzira muhutano hwepamusoro hwesimbi yakasviba kuti ugadzikane phosphorurative solution uye uvandudze kushanda kwe phosphorus membrane;
9. Sekuwedzera mukugadzirwa kwezvinhu zvekuisa chisimbiso uye brake pads, inobata basa mukuwedzera kupfeka kusagadzikana;
10. Sezvinowedzera mukongiri, simbisa kupikisa kwekongiri.
Zvekungwaririra:
1. Shandisa sodium fluoride kunyatso kudzora huwandu hwefluorine zuva nezuva kudzivirira kugadzirwa kwefluoride chepfu;
2. Sodium fluoride solution kana gel inofanira kuiswa mumudziyo wepurasitiki;
3. Varwere, vakadzi vane pamuviri, vakadzi vanoyamwisa, kupfava kwepfupa uye kukanganisa kwerenal munzvimbo dzakakwirira-fluoride zvinorambidzwa.
