Fluorine - 9F: uses
The following uses for fluorine are gathered from a number of sources as well as from anecdotal comments. I would be delighted to receive corrections as well as additional referenced uses.
- fluorine and its compounds are used in producing isotopically fractionated uranium (from UF6)
- commercial fluorochemicals, including many well known high-temperature plastics
- hydrofluoric acid is extensively used for etching the glass of light bulbs, etc.
- fluorochloro hydrocarbons are used extensively in air conditioning and refrigeration
- in small amounts, fluorides in water sources prevent tooth decay. A constituent of toothpaste for the same reason. Soluble fluoride in drinking water (2 ppm) may cause mottled enamel in teeth of children acquiring permanent teeth.
Fluorine - 9F: matumizi Matumizi ya fluorine yafuatayo yamekusanywa kutoka vyanzo kadhaa na pia kutoka kwa maoni ya anecdotal. Ningependa kupokea marekebisho pamoja na matumizi ya ziada yaliyotajwa. Fluorine na misombo yake hutumiwa katika utengenezaji wa uranium ya isotopically fractionated (kutoka UF6) - kemikali za kibiashara za fluorine, ikiwa ni pamoja na plastiki nyingi za joto la juu - asidi ya hydrofluoric hutumiwa sana kwa kuchoma kioo cha taa, nk. Fluorochlorine hydrocarbons ni kutumika sana katika hali ya hewa na baridi. fluorides katika maji ya maji kuzuia kuoza meno. Ni sehemu ya dawa ya meno kwa sababu hiyohiyo. Fluoride inayoweza kuyeyuka katika maji ya kunywa (2 ppm) inaweza kusababisha enamel ya madoa katika meno ya watoto wanaopata meno ya kudumu.
