Mashandisirwo eSodium fluoride

Sodium fluoride; NaF；SF; Inorganic Fluoride, Ikristaro isina ruvara kana upfu huchena hunopenya, ndeye tetragonal system, ine positive hexahedral kana octahedral crystals. Inonyungudika zvishoma mualcohol, inonyungudika mumvura. Mvura ine acidic. Inonyungudika mu hydrofluoric acid kugadzira sodium hydrogen fluoride.
1. Sodium fluoride inonyanya kushandiswa sesimbi inoiswa mukati mesimbi ye ...
2. Sodium fluoride inoshandiswa semishonga inouraya utachiona, mishonga yekuchengetedza, mishonga yezvipembenene, inoshandiswawo mu enamel, kuchengetedza huni, mishonga, simbi, kugadzira fluorides nezvimwewo.
3. Inoshandiswa pakuongorora scandium mukuongorora kwe microanalysis, kuona phosphorus mukuongorora kwe photoelectric colorimetric, inoshandiswa se reagent, masking agents, preservatives yesimbi nesimbi.
4. Sezvinowedzera zvekudya. Zvinoenderana nemutemo wekuChina wemunyu, kushandiswa kwakanyanya i0.1g/kg.
5. Inoshandiswa semishonga yekuchengetedza matanda, mishonga yekuchengetedza, welding flux uye inoshandiswa muindasitiri yemapepa, zvigadzirwa zvekambani iyi mishonga yemazino yakaenzana, inogona kushandiswawo senzira yekuchenesa mvura yekunwa, uye inoshandiswa pakuchenesa matehwe neganda muindasitiri yekuchenesa ganda, yekunyungudutsa nekunatsa simbi isina kujeka, uye yekudzivirira simbi isina kujeka, yekuora kwenamira, uye kugadzira simbi inopisa.
6. Sodium fluoride inoshandiswa sePhosphate accelerator muindasitiri yekupenda, inoita kuti phosphate irambe yakasimba, phosphate iwedzere kunaka, uye inovandudza mashandiro e phosphate coating. Aluminium ne alloys dzayo phosphate zvinogona kuvhara negative catalytic Al3+ yengozi huru, uye zvinoita kuti phosphate ibude zvakanaka. Inoshandiswa semiti inochengetedza, mishonga yekurima, fungicides muindasitiri yekubika, mishonga inochengetedza mishonga, welding flux, alkaline zincate zinc additives uye enamel, bepa nezvimwewo.
