Mugadziri akanaka mutengo sodium fluoride cas: 7681-49-4

Sodium froride; Naf; SF; Inorganic fluoride, iyo isina mavara makristasi kana kuti inopenya chena poda, ndeyako tetragonal system, yakanaka hexahedral kana octahedral makristasi. Izvo zvinonyangadza zvishoma nedoro, zvinyoro-nyoro mumvura. Mhinduro yemvura ndeye acidic. Iyo inodonha mu hydrofluorgic acid kuti iite sodium hydrogen fluoride.
1. Sodium Fluoride inonyanya kushandiswa sechigaro chechigadzika chehuni uye planensi yekuwedzera kusimbisa kweWels Simba. Kechipiri, inoshandiswa sehuni dzinochengetedza, dzinofungidzira muBrewitives muindasitiri, dzinofanirwa kutapukirwa nebhuruu), zvekuchengetedza zvekuchengetedza, Welding flux, fluorine mumiririri wekunwa mvura. Zvakare zvinoshandiswa kugadzira imwe fluoride uye kesiin glue, sodium fluoride mazino, sekumaodzanyemba, zvakare inoshandiswa mupepa uye maindasitiri ezvesimbi. Mukugadzirwa kwelemental fluorine, inoshandiswa kubvisa trace huwandu hwe hydrogen fluoride. Mukuwedzera, inoshandiswawo mu enamels uye maindasitiri emishonga.

4. Sezvo chikafu chekudya. Sekureva kweChinese mirairo yemunyu, iyo yakanyanya kushandiswa ndeye 0.1g / kg.
5. Izvo zvinoshandiswa sehuni dzinochengetedza, mishonga yekuchengetedza uye inoshandiswa mune yepepa indasitiri, inogona zvakare kushandiswa seinenge ichinatsa mvura, uye inoshandiswa pakuvanda uye kugadzirira kweganda muindasitiri yekucheka, Zvekunyepa uye kunatsa kwechiedza simbi, uye chivimbo chesimbi yechiedza, chekunamatira kurongeka, uye kugadzira simbi yekubika.
6. Sodium Floride inoshandiswa se phosphate yekuwedzera muCoatingator Aluminium uye Alloys yayo phosphate inogona kuvhara zvisina kunaka catalytic al3 + yengozi huru, uye kuita kuti pfungwa ishe zvakanaka. Izvo zvinoshandiswa sehuni dzinochengetedza, marimba ekurima, fungides muBrewitive Indasitiri, mishonga yekuchengetedza, Welding flux, alkaline zincate zinc anowedzera uye enamel, pepa uye zvichingodaro.
