Ukusetyenziswa kweSodium fluoride

Isodium fluoride;I-NaF;I-Inorganic Fluoride, Yikristale engenambala okanye umgubo omhlophe omenyezelayo, ungowenkqubo ye-tetragonal, i-hexahedral entle okanye i-octahedral crystals.Iyanyibilika kancinci etywaleni, inyibilika emanzini.Isisombululo esinamanzi sineasidi.Inyibilika kwi-hydrofluoric acid ukwenza i-sodium hydrogen fluoride.
1. Isodium fluoride isetyenziswa kakhulu njengentsimbi eYayiweyo yeblade yoomatshini kunye neplani yokwandisa ukomelela kweweld.Okwesibini, isetyenziswa njengezithinteli zokhuni, i-fungicides kwishishini lotywala, i-pesticides yezolimo (kufuneka yosuleleke ngeblue), izigcini zonyango, i-welding flux, i-agent ye-fluorine yamanzi okusela.Ikwasetyenziselwa ukuvelisa enye i-fluoride kunye ne-casein glue, intlama yamazinyo ye-sodium fluoride, njengezinto zokuncamathelisa, ikwasetyenziswa kumashishini ephepha kunye nesinyithi.Kwimveliso yefluorine esisiseko, isetyenziselwa ukususa amanani omkhondo wehydrogen fluoride.Ukongeza, ikwasetyenziswa kwi-enamels kunye namashishini amayeza.
2. I-sodium fluoride isetyenziswa njengezibulali-ntsholongwane, izigcina- ntsholongwane, izitshabalalisi, izitshabalalisi, ikwasetyenziswa kwi-enamel, ukugcinwa kweenkuni, amayeza, isinyithi, ukwenziwa kweefluoride njalo njalo.
3. Isetyenziselwa ukuzimisela kwe-scandium kwi-microanalysis, ukuzimisela kwe-phosphorus kwi-photoelectric colorimetric analysis, esetyenziswe njenge-reagent, i-mask agents, i-preservatives yentsimbi kunye nentsimbi.
4. Njengezongezo zokutya.Ngokwemigaqo yaseTshayina yetyuwa, ukusetyenziswa okuphezulu ngu-0.1g / kg.
5. Isetyenziswa njengezinto zokukhusela iinkuni, i-pharmaceutical preservative, i-welding flux kwaye isetyenziswe kumashishini ephepha, iimveliso zale nkampani zinezinga elithile lokuxutywa kwamazinyo, zinokusetyenziswa njenge-arhente yokucoca kumanzi okusela, kwaye isetyenziselwa izikhumba kunye nokucutshungulwa kwesikhumba kwishishini le-tanning; ukunyibilikiswa kunye nokusulungekiswa kwesinyithi esikhanyayo, kunye nokhuselo lwesinyithi esikhanyayo, ukuhlwa okuncamathelayo, kunye nokwenza intsimbi ebilayo.
6. I-sodium fluoride isetyenziswe njenge-accelerator ye-Phosphate kwi-coating industry, yenza i-phosphating isisombululo sozinzo, ukulungiswa kwe-phosphate, iphucula ukusebenza kwe-phosphate coating.I-aluminiyam kunye ne-alloys yayo ye-phosphate inokuvala i-al3 engalunganga ye-catalytic yengozi enkulu, kwaye yenze i-phosphating kakuhle.Isetyenziswe njengezithinteli zokhuni, izitshabalalisi zezolimo, imichiza yokungunda kwishishini lotywala, i-pharmaceutical preservative, i-welding flux, i-alkaline zincate izongezo ze-zinc kunye ne-enamel, iphepha njalo njalo.
