Sodium fluoride kanye amazinyo

Fluorine compounds avame ukusetshenziswa kwezokwelapha nakweminye imikhakha. Wona fluoro - ikhemikhali lisasesimweni gaseous, ngakho umthombo sasekhaya kuyinto fluoride - sasekhaya compounds ngezinto ezihlukahlukene, kuhlanganise metal. Ezinye zalezi compounds, esetshenziswa kakhulu - sodium fluoride kanye ne-aluminium.

Cishe zonke-fluoride - into kuyinto ngempela enobuthi emzimbeni womuntu. Inani sasekhaya, okuyinto equkethwe kuphela ishubhu elilodwa wokuxubha, kungaba okwanele ukuze asuse impilo omncane oneminyaka emibili ubudala. Ngokuvamile, emakamu sasekhaya kunoma iyiphi imvelo lingaphansi kakhulu kunezinye ngamapayipi wokuxubha emazinyweni.

Sodium fluoride - a crystalline, powder kungekho nto enemibala emihle. Ingqikithi kuyinto usawoti sodium. ukuncibilika wayo iphuzu oluhambisana 997 degrees. It amathumba ezingeni lokushisa phezu 1700 degrees Celsius. Sodium fluoride isetshenziswa emikhakheni eminingi, kuhlanganise kwemithi imithi. - ikakhulukazi amazinyo.

umphumela kwemithi sodium fluoride ngokuyisisekelo liqukethe ukugcwalisa ukushoda sasekhaya esigulini. Kube ingashiwo amanxusa kanye anticaries umphumela kwakwakhe sasekhaya ezisekelwe. Abanye odokotela, ukuze kuvinjelwe ukubukeka caries, izingane, ngubani isukela kweminyaka emibili nengu kwemithathu kuya kweyisithupha, kunconywa kanye ngosuku ukwenza sodium fluoride imali engafika ku-1.1 mg. Ukuthatha imithi enjalo kudingeka emva kokudla ngomlomo ngamanzi. Esemncane enjalo ezimise koqweqwe lwawo ngezinyo, futhi, uma ukuthi kulesi sigaba ukufaka sasekhaya, amazinyo kuyoba Bole kakhulu ukumelana amagciwane - Amagciwane of caries kwamazinyo. Anticaries umphumela fluoride, oyingxenye wokuxubha, wukuthi ion lomcebo engene izilokazane ezincane amagciwane - agent causative of caries zamazinyo, ivimbela wakhe glucose ukucutshungulwa umsebenzi - okuwukuthi, lokho kwenza la magciwane siphile futhi ande. Igciwane, ubuthi sasekhaya, ezifayo, asikwazanga ukusebenza ne-glucose ngaleyo ndlela khona. Nokho, one-fluoride kuyinto anobuthi ukuze wahlushwa nezilwanyana ezincane hhayi kuphela eziyingozi, kodwa futhi kwamanye amangqamuzana.

Athomu fluoride kufakwe fluoride sodium, i-calcium sisimamiswe inqubo ithambo kwezinsalela namaminerali. Ziyakwazi esisemqoka uma ukwakha izindwangu amazinyo futhi izinyo koqweqwe lwawo. Ukwakhiwa ngokusekelwe ukusetshenziswa fluoride ekwelapheni kwamathambo. Ukwakhiwa ngazo zihlanganisa sodium fluoride, ugxile ngemva kokuzibeka elangeni ngomlomo.

Kwezinye izimo, i-sodium fluoride ngesikhathi ukungenisa njalo, kungabangela ezinye izinkinga zempilo - iziyaluyalu wokugaya ukudla noma ubuthi. Ngakho-ke, asikho isidingo ukuba unqume ukuthi kufanele yini ukuthatha izidakamizwa, futhi kungcono ukuthintana nodokotela. Abantu ne ezinzima kwezinso noma isifo sesibindi exacerbation duodenum noma esiswini, thatha contraindicated sodium-fluoride. ukusetshenziswa noma nqatshelwe ke ngesikhathi sokukhulelwa, ubuhlengikazi kanye nezingane, ogama yobudala ingeqi engu-3, akufanele inikezwe izidakamizwa equkethe lokhu izidakamizwa.

Fluorides ngezinto ezihlukahlukene angase abe izakhiwo ezahlukene. Ngokwesibonelo, uma lesi sithako sodium fluoride kabanzi lisetshenziswe imithi nokuphila (wokuxubha, amanzi kanye al fluorinated.) Ukuze ukwelashwa kanye nokuvinjelwa kwezifo ezithile, one-fluoride aluminium is cishe hhayi kusetshenziswa imithi. It is lisetshenziswe ukukhiqizwa - kusukela electrolysis aluminium kanye ukukhiqizwa ezinye izinto.

Aluminium fluoride - futhi kuyinto crystal kungekho nto enemibala emihle. Lapho ukufuthelana wokhela ngokushesha, ngaphandle ukuncibilika. Aluminium fluoride kuyinto kabi encibilikayo, ngokungafani sodium-fluoride. Ukusetshenziswa Its ngesikhathi ukulungiselela kanye ukuhlanzwa aluminiyamu metal. Futhi fluoride aluminium lubaluleke ekukhiqizeni kwezinye izinto - ngokwesibonelo, enamels, fluxes futhi izitsha zobumba. Afakwe ezinengilazi we electrode esetshenziselwa Welding. Iphinde isetshenziselwe njengenhlangano isinqandakuvunda enqubeni lwezithelo olubangela ukubila.
