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. Isetyenziswe njengezinto zokukhusela iinkuni, i-pharmaceutical preservative, i-welding flux kwaye isetyenziswe kumashishini ephepha, iimveliso zale nkampani zinezinga elithile le-toothpastes, ingasetyenziselwa njenge-arhente yokucoca amanzi okusela, kwaye isetyenziselwa izikhumba kunye nokulungiswa kwesikhumba kwi-industry ye-tanning, ukunyibilikisa kunye nokucokisa isinyithi esikhanyayo, kunye nokukhusela i-metal corrosion, i-adhesive steel, i-adhesive steel, i-adhesive steel, i-adhesive steel, kunye ne-adhesive steel, i-adhesive steel, i-adhesive steel, i-adhesive steel, i-adhesive steel corrosion, i-adhesive adhesive adhesive-search agents.
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.
