I-Sodium Fluoride

I-sodium fluoride,iwuhlobo lwenhlanganisela ye-inorganic, ifomula yamakhemikhali i-NaF, esetshenziswa kakhulu embonini yokumboza njenge-accelerator ye-phosphating, i-insecticide yezolimo, izinto zokuvala uphawu, izivimbelakuvunda nezinye izinkambu.

Izakhiwo Zomzimba:Ukuminyana okuhlobene ngu-2.558 (41/4 ​​° C), indawo yokuncibilika ngu-993 ° C, futhi iphoyinti lokubilisa ngu-1695 ° C [1]. (Ukuminyana okuhlobene 2.79, indawo encibilikayo 992 ° C, indawo yokubilisa 1704 ° C [3]) Incibilika emanzini (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100gchemicalbook), encibilika ku-hydrofluoric acid, futhi engancibiliki ku-ethanolic. Isixazululo esinamanzi sine-alkaline (pH = 7.4). Ubuthi (umonakalo ohlelweni lwezinzwa), LD50180mg/kg (amagundane, ngomlomo), 5-10 amagremu ukufa. Izakhiwo: i-crystalline powder engenambala noma emhlophe, noma amakristalu ayi-cubic, amakristalu amahle, angenaphunga.

Izakhiwo zamakhemikhali:ikristalu ecwebezelayo engenambala noma impushana emhlophe, uhlelo lwe-tetragonal, olunamakristalu avamile angama-hexahedral noma ama-octahedral. Incibilika kancane otshwaleni; Incibilika emanzini, isixazululo esinamanzi simuncu, sincibilika ku-hydrofluoric acid ukwenza i-sodium hydrogen fluoride.

Isicelo:

1. Ingasetshenziswa njengensimbi ephezulu ye-carbon, njenge-agent efaka umoya wensimbi ebilayo, i-aluminium electrolytic noma i-electrolytic refined agent, ukwelashwa okungangeni manzi kwephepha, izilondolozi zezinkuni (nge-sodium fluoride ne-nitrate noma i-diitol phenol Ukuze uthole i-anti-corrosion yezinto eziyisisekelo), sebenzisa izinto (amanzi okuphuza, imithi yokuxubha amazinyo, njll).

2. Isetshenziselwa ukuvimbela i-caries yamazinyo kanye ne-oral caries ngokuntuleka kwe-fluoride emanzini emanzini emanzini;

3. Imithamo emincane isetshenziselwa ikakhulukazi i-osteoporosis kanye nesifo se-paget bone;

4. Ingasetshenziswa njengezinto ezingavuthiwe noma umunci we-fluoride wenye i-fluoride noma i-fluoride;

5. Ingasetshenziswa njenge-adsorbent ye-UF3 kuma-ejenti okwelapha usawoti we-fluorine wensimbi elula, izicwengisisi zokuncibilikisa, nezimboni zenuzi;

6. Isixazululo sokuwasha sensimbi nezinye izinsimbi, ama-agent ashiselwe nama-welds;

7. I-Ceramics, ingilazi kanye ne-koqweqwe lwawo luyancibilika kanye nama-shading agents, isikhumba esiluhlaza kanye nama-ejenti okwelapha e-epidermal embonini yethoni;

8. Yenza abagqugquzeli be-phosphate ekwelapheni okungaphezulu kwensimbi emnyama ukuzinzisa isisombululo se-phosphorurative futhi kuthuthukiswe ukusebenza kwe-membrane ye-phosphorus;

9. Njengesengezo ekukhiqizeni izinto zokuvala kanye nama-brake pads, idlala indima ekwandeni kokumelana nokugqoka;

10. Njengezithako kukhonkolo, thuthukisa ukumelana nokugqwala kokhonkolo.

Izinyathelo zokuzivikela:

1. Sebenzisa i-sodium fluoride ukulawula ngokuqinile inani le-fluorine nsuku zonke ukuvimbela ukukhiqizwa kobuthi be-fluoride;

2. Isixazululo se-sodium fluoride noma ijeli kufanele ifakwe esitsheni sepulasitiki;

3. Iziguli, abesifazane abakhulelwe, abancelisayo, ukuthamba kwamathambo kanye nokwehluleka kwezinso ezindaweni ezine-fluoride ephezulu akuvunyelwe.

Ukupakisha nokugcina

Indlela yokupakisha:izikhwama zepulasitiki noma izikhwama ezimbili zesikhumba senkomo imiphongolo yangaphandle yebhodi, imiphongolo yeplywood, imiphongolo yebhodi eliqinile; imiphongolo yepulasitiki (eqinile) ngaphandle kwezikhwama zepulasitiki; imiphongolo yepulasitiki (uketshezi); izingqimba ezimbili zezikhwama zepulasitiki noma isikhwama esisodwa sepulasitiki esingaphandle kwamasaka, ukwelukwa kwepulasitiki, ukwelukwa kwepulasitiki Izikhwama, izikhwama ze-latex; isikhwama sepulasitiki esiyinhlanganisela izikhwama zepulasitiki nokwelukiweyo (polypropylene ezintathu-in -one izikhwama, polyethylene izikhwama triple, polypropylene izikhwama ezimbili -kukodwa, polyethylene ezimbili -in - eyodwa isikhwama); izikhwama zepulasitiki noma izikhwama ezimbili zesikhumba zesikhumba ngaphandle kwebhokisi lezinkuni elivamile; ibhodlela lengilazi elinentambo, ikhava yensimbi cindezela ibhodlela lengilazi, ibhodlela lepulasitiki noma umgqomo wensimbi (ithini) ibhokisi lokhuni elijwayelekile; ibhodlela lengilazi elinentambo, ibhodlela lepulasitiki noma umphongolo wensimbi ocwecwe (ikani) Ibhokisi, ibhokisi le-fiberboard noma ibhokisi le-plywood.Ukupakishwa komkhiqizo: 25kg/isikhwama.

Izinyathelo zokuphepha zokulondoloza nezokuthutha:Ngesikhathi sokuthutha ngololiwe, itafula lokuhlanganisa impahla eyingozi kufanele lifakwe ngokuvumelana nemithetho yoMnyango Wezitimela Wesitimela Eyingozi Yezokuthutha. Ngaphambi kokuthutha, hlola ukuthi isitsha sokupakisha siphelele futhi sivaliwe yini. Ngesikhathi sokuthutha, kufanele kuqinisekiswe ukuthi isitsha akufanele sivuze, sidilike, siwe, noma silimale. Kwenqatshelwe ngokuphelele ukuxuba ne-asidi, i-oxidant, ukudla kanye nezithasiselo zokudla. Ngesikhathi sokuthutha, izimoto zokuthutha kufanele zifakwe imishini yokwelapha izimo eziphuthumayo ezivuzayo. Ngesikhathi sokuthutha, ukukhanya kwelanga nemvula kufanele kuvezwe ukuvimbela izinga lokushisa eliphezulu. Gcina endaweni epholile, eyomile, nengena umoya. Izinga lokushisa emtatsheni wezincwadi aweqi ku-30 ​​° C, futhi umswakama ohlobene aweqi ama-80%. Ukupakisha nokuvala. Gcina ngokwehlukana ku-asidi namakhemikhali adliwayo, gwema ukuxutshwa. Indawo yokugcina izoba nezinto ezifanele zokuqukatha ukuvuza. Sebenzisa ngokuqinile uhlelo lokulawula "okuphindwe kabili" lwezinto ezinobuthi.
