Sodium fluoride thiab kev kho hniav

Fluorine tebchaw yog feem ntau siv rau hauv cov tshuaj thiab lwm yam liaj teb. Nws tus kheej Fluoro - ib yam khoom uas yog nyob rau hauv lub gaseous lub xeev, yog li lub fluorine qhov chaw yog fluoride - fluorine tebchaw nrog rau ntau yam ntaub ntawv, nrog rau cov hlau. Ib txhia ntawm cov tebchaw, feem ntau siv - yog sodium tshuaj fluoride thiab txhuas.

Yuav luag tag nrho cov tshuaj fluoride - ib yam khoom uas yog heev tshuaj lom rau tib neeg lub cev. Tus nqi ntawm cov fluorine, uas yog muaj xwb nyob rau hauv ib tug raj tshuaj txhuam hniav, yuav txaus rau noj tam sim ntawd lub neej ntawm lub me ntsis ob xyoos. Nyob rau hauv dav dav, lub fluorine concentration nyob rau hauv tej ib puag ncig yog tsawg dua nyob rau hauv ib tug raj tshuaj txhuam hniav rau cov hniav.

Sodium Fluoride - ib tug crystalline, tsis muaj kob hmoov. Cov tshuaj yeeb dej caw yog ib tug sodium ntsev. Nws melting point sau raws nkaus Ii 997 degrees. Nws boils ntawm ib tug kub tshaj 1700 degrees Celsius. Sodium fluoride yog siv nyob rau hauv ntau lub teb, xws li pharmacology thiab tshuaj. - tshwj xeeb tshaj yog nyob rau hauv kev kho hniav.

Pharmacological nyhuv ntawm sodium tshuaj fluoride yeej muaj nyob rau hauv sau shortage ntawm fluorine nyob rau hauv tus neeg mob. Muaj tej zaum yuav hais cov neeg ua hauj thiab anticaries nyhuv fluorine-raws li compound. Ib txhia kws kho mob, nyob rau hauv thiaj li yuav tiv thaiv tau cov tsos ntawm caries, cov me nyuam, uas ntsuas nyob rau hauv lub hnub nyoog los ntawm peb mus rau rau lub xyoo, nws yog pom zoo kom ib hnub ib zaug yuav ua rau sodium tshuaj fluoride nyob rau hauv cov nqi ntawm cov mus 1.1 mg. Noj xws tshuaj xav tau tom qab noj mov ncauj nrog dej. Thaum xws li ib tug hluas uas muaj hnub nyoog zoo li tus tus hniav enamel, thiab, muab hais tias nws yog nyob rau ntawm no theem rau muaj xws li fluorine, cov hniav yuav muaj ntau yam Bole resistant rau microbes - pathogens ntawm kev kho hniav caries. Anticaries nyhuv ntawm fluoride, uas yog ib feem ntawm cov tshuaj txhuam hniav, yog hais tias ions ntawm tshuaj tau txais mus rau hauv lub kab mob cov kab mob - lub causative tus neeg saib xyuas ntawm kev kho hniav caries, thaiv cov hlab nws glucose ua muaj nuj nqi - uas yog, dab tsi ua rau cov kab mob nyob thiab ua multiply. Cov kab mob, tshuaj lom los ntawm fluorine, tuag, tsis tau ua piam thaj thiab yog li ua ib ke. Txawm li cas los, fluoride yog tshuaj lom kom nws raug kev txom nyem los ntawm tsis tsuas teeb meem kab mob, tab sis kuj lwm lub hlwb.

Cov tshuaj fluoride ions nyob rau hauv lub sodium tshuaj fluoride, calcium nyob ruaj hauv tus txheej txheem ntawm cov pob txha mineralization. Lawv yog cov tseem ceeb thaum txoj kev fabrics ntawm cov hniav thiab cov hniav enamel. Formulations raws li nyob rau kev siv ntawm fluoride nyob rau hauv cov kev kho mob ntawm kab mob. Formulations uas muaj xws li sodium tshuaj fluoride, absorbed tom qab qhov ncauj raug.

Nyob rau hauv tej rooj plaub, sodium tshuaj fluoride ntawm qhov haus, yuav ua rau ib txhia noj qab haus huv tej teeb meem - digestive mob los yog raug tshuaj lom. Yog li ntawd, nws tsis yog tsim nyog los txiav txim siab seb puas los yog tsis txhob coj tus yeeb tshuaj, thiab nws yog zoo dua rau sab laj ib tug kws kho mob. Cov neeg uas muaj mob loj heev raum lossis daim siab tus kab mob exacerbation duodenum los yog plab, noj txhob sodium tshuaj fluoride. siv no kuj txwv tsis pub nws thaum lub sij hawm cev xeeb tub, laus thiab cov me nyuam, uas nws muaj hnub nyoog tsis tshaj 3 xyoos, yuav tsum tsis txhob muab tshuaj muaj no substance.

Fluorides ntawm ntau yam co yuav muaj ntau zog. Piv txwv li, yog hais tias tus compound yog sodium tshuaj fluoride yog dav siv nyob rau hauv cov tshuaj thiab lub neej (cov tshuaj txhuam hniav, dej thiab fluorinated al.) Rau cov kev kho mob thiab kev tiv thaiv ntawm tej yam kab mob, lub txhuas fluoride yog xyaum tsis siv nyob rau hauv cov tshuaj. Nws yog siv nyob rau hauv qhuav - los ntawm lub txhuas electrolysis thiab zus tau tej cov ib co ntaub ntawv.

Aluminium fluoride - kuj yog tsis muaj kob siv lead ua. Thaum rhuab ignites sai sai, tsis muaj melting. Aluminium fluoride yog tsis zoo soluble, tsis zoo li sodium tshuaj fluoride. Nws siv thaum lub sij hawm cov kev npaj thiab purification ntawm txhuas hlau. Tsis tas li ntawd txhuas fluoride yog indispensable nyob rau hauv zus tau tej cov ib co ntaub ntawv - piv txwv li, enamels, fluxes thiab ceramics. Muaj nyob rau hauv lub coatings ntawm lub electrodes siv rau welding. Nws kuj yog siv raws li ib tug antiseptic nyob rau hauv lub fermentation txheej txheem.
