I-sodium fluoride,uhlobo lwenhlanganisela engaphili, ifomula yamakhemikhali yi-NaF, esetshenziswa kakhulu embonini yokumboza njenge-phosphating accelerator, i-insecticide yezolimo, izinto zokuvala, izilondolozi kanye neminye imikhakha.
Izakhiwo Ezibonakalayo:Ubuningi obuhlobene bungu-2.558 (41/4 ° C), iphuzu lokuncibilika lingu-993 ° C, kanti iphuzu lokubila lingu-1695 ° C [1]. (Ubuningi obuhlobene 2.79, iphuzu lokuncibilika 992 ° C, iphuzu lokubila 1704 ° C [3]) Incibilika emanzini (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100g chemicalbook), incibilika ku-hydrofluoric acid, futhi ayincibiliki ku-ethanol. Isixazululo samanzi siyi-alkaline (pH = 7.4). Inobuthi (isistimu yezinzwa elimazayo), i-LD50180mg/kg (amagundane, ngomlomo), amagremu angu-5-10 aze afe. Izakhiwo: impuphu yekristalu engenambala noma ngisho emhlophe, noma amakristalu e-cubic, amakristalu amahle, angenaphunga.
Izakhiwo zamakhemikhali:Ikristalu ecwebezelayo noma impuphu emhlophe engenambala, uhlelo lwe-tetragonal, olunezikristalu ezijwayelekile ze-hexahedral noma ze-octahedral. Incibilika kancane otshwaleni; Incibilika emanzini, isixazululo samanzi sinobuthi, sincibilika ku-hydrofluoric acid ukuze sakhe i-sodium hydrogen fluoride.
Isicelo:
1. Ingasetshenziswa njengensimbi enekhabhoni ephezulu, njenge-ejenti engangenisi umoya yensimbi ebilayo, i-ejenti yokuncibilikisa ecwengisisiwe ye-aluminium noma ye-electrolytic, ukwelashwa kwephepha okungangeni manzi, izithasiselo zokhuni (ezine-sodium fluoride ne-nitrate noma i-diitol phenol. Ukuze kuvinjelwe ukugqwala kwezinto eziyisisekelo), sebenzisa izinto (amanzi okuphuza, umuthi wokuxubha amazinyo, njll.), izibulali zinambuzane, izithasiselo zokubulala izinambuzane, izithasiselo zokuvikela, njll.
2. Isetshenziselwa ukuvimbela ukubola kwamazinyo kanye nokubola komlomo lapho kungekho i-fluoride emanzini emanzini;
3. Imithamo emincane isetshenziswa kakhulu ekwelapheni i-osteoporosis kanye nesifo samathambo se-paget;
4. Ingasetshenziswa njengezinto zokusetshenziswa noma njenge-fluoride emunca enye i-fluoride noma i-fluoride;
5. Ingasetshenziswa njenge-adsorbent ye-UF3 kuma-ejenti okwelapha usawoti we-fluorine wensimbi ekhanyayo, kuma-refiner okuncibilikisa, kanye nasezimbonini zenuzi;
6. Isixazululo sokuwasha sensimbi nezinye izinsimbi, ama-ejenti ahlanganisiwe kanye nama-weld;
7. Izinto zobumba, ingilazi kanye nezinto zokuncibilikisa i-enamel kanye nezinto zokufiphaza, izinto zokwelapha isikhumba esiluhlaza kanye ne-epidermal embonini ye-tone;
8. Yenza abagqugquzeli be-phosphate ekwelapheni insimbi emnyama ebusweni ukuze kuqiniswe isisombululo se-phosphorus futhi kuthuthukiswe ukusebenza kwe-membrane ye-phosphorus;
9. Njengesengezo ekukhiqizweni kwezinto zokuvala kanye nama-brake pad, idlala indima ekwandiseni ukumelana nokuguguleka;
10. Njengezithasiselo kukhonkolo, thuthukisa ukumelana kokugqwala kukhonkolo.
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 kufakwe esitsheni sepulasitiki;
3. Iziguli, abesifazane abakhulelwe, abesifazane abancelisayo, ukuthamba kwamathambo kanye nokwehluleka kwezinso ezindaweni ezine-fluoride ephezulu akuvunyelwe.
Ukupakisha nokugcina
Indlela yokupakisha:izikhwama zepulasitiki noma isikhwama sephepha esinezingqimba ezimbili zesikhumba senkomo imiphongolo yebhodi le-fiber yangaphandle, imiphongolo ye-plywood, imiphongolo yebhodi lephepha eliqinile; imiphongolo yepulasitiki (eqinile) izikhwama zepulasitiki zangaphandle; imiphongolo yepulasitiki (uketshezi); izendlalelo ezimbili zezikhwama zepulasitiki noma isikhwama sepulasitiki esinezingqimba eyodwa izikhwama zangaphandle, ukuluka kwepulasitiki, ukuluka kwepulasitiki Izikhwama, izikhwama ze-latex; isikhwama sepulasitiki izikhwama ezihlanganisiwe zepulasitiki ezilukiwe (izikhwama ze-polypropylene ezintathu-in-one, izikhwama ze-polyethylene ezintathu-in-one, izikhwama ze-polyethylene ezimbili-in-one, isikhwama se-polyethylene ezimbili-in-one); izikhwama zepulasitiki noma izikhwama zephepha lesikhumba ezimbili-in-one ngaphandle kwebhokisi lezinkuni elijwayelekile; ibhodlela lengilazi yochungechunge, ibhodlela lengilazi yokucindezela yensimbi, ibhodlela lepulasitiki noma ibhodlela lensimbi (ithini) ibhokisi lezinkuni elivamile; ibhodlela lengilazi yochungechunge, ibhodlela lepulasitiki noma ithini elifakwe ipuleti lensimbi elincane (ithini) Ibhokisi, ibhokisi le-fiberboard noma ibhokisi le-plywood. Ukupakishwa komkhiqizo: 25kg/isikhwama.
Izinyathelo zokuphepha zokugcina nokuthutha:Ngesikhathi sokuthuthwa kwesitimela, itafula lokuhlanganisa imithwalo eyingozi kufanele lifakwe ngokuhambisana neMithetho Yokuthutha Imithwalo Eyingozi YoMnyango Wezitimela Wezitimela. Ngaphambi kokuthutha, hlola ukuthi isitsha sokupakisha siphelele futhi sivaliwe. Ngesikhathi sokuthutha, kufanele siqinisekise ukuthi isitsha akufanele sivuze, sibhidlike, siwe, noma sonakale. Akuvunyelwe ngokuphelele ukuxuba ne-asidi, i-oxidant, ukudla kanye nezithasiselo zokudla. Ngesikhathi sokuthutha, izimoto zokuthutha kufanele zifakwe imishini yokwelapha ephuthumayo yokuvuza. Ngesikhathi sokuthutha, ukuchayeka elangeni kanye nemvula kufanele kuvezwe ukuze kuvinjelwe izinga lokushisa eliphezulu. Gcina endaweni yokugcina impahla epholile, eyomile, nengenawo umoya. Izinga lokushisa lomtapo wolwazi alidluli ku-30 ° C, kanti umswakama ohlobene awudluli ku-80%. Ukupakisha nokuvala. Gcina ngokuhlukile kumakhemikhali e-asidi nalawo adliwayo, gwema ukuxuba. Indawo yokugcina kufanele ibe nezinto ezifanele zokuvimba ukuvuza. Sebenzisa ngokuqinile uhlelo lokuphatha "oluphindwe kahlanu" lwezinto ezinobuthi.
