I-Sodium Fluoride

I-sodium fluoride,luhlobo lwekhompawundi engangcolisiyo, ifomula yekhemikhali yiNaF, esetyenziswa kakhulu kushishino lokugquma njenge-phosphating accelerator, i-insecticide yezolimo, izinto zokutywina, izithinteli kunye nezinye iinkalo.

Iimpawu Zomzimba:Uxinano oluhambelanayo yi-2.558 (41/4 ​​° C), iqondo lokunyibilika yi-993 ° C, kwaye iqondo lokubila yi-1695 ° C [1]. (Uxinano oluhambelanayo yi-2.79, iqondo lokunyibilika yi-992 ° C, iqondo lokubila yi-1704 ° C [3]) Inyibilika emanzini (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100g chemicalbook), iyanyibilika kwi-hydrofluoric acid, kwaye ayinyibiliki kwi-ethanol. Isisombululo samanzi yi-alkaline (pH = 7.4). Inetyhefu (inkqubo yemithambo-luvo eyonakalisayo), i-LD50180mg/kg (iimpuku, zomlomo), iigram ezi-5-10 ukuya ekufeni. Iimpawu: umgubo wekristale ongenanto okanye omhlophe, okanye iikristale zetyhubhu, iikristale ezintle, ezingenavumba.

Iimpawu zekhemikhali:Ikristale ekhazimlayo okanye umgubo omhlophe ongenambala, inkqubo ye-tetragonal, enekristale eziqhelekileyo ze-hexahedral okanye ze-octahedral. Inyibilika kancinci kwi-alcohol; Inyibilika emanzini, isisombululo samanzi sine-asidi, inyibilika kwi-hydrofluoric acid ukwenza i-sodium hydrogen fluoride.

Isicelo:

1. Ingasetyenziswa njengentsimbi enekhabhoni ephezulu, njengearhente engangeni moya yentsimbi ebilayo, iarhente yokunyibilikisa ecociweyo ye-aluminium electrolytic okanye electrolytic, unyango olungangeni manzi lwephepha, izigcini zomthi (ezine-sodium fluoride kunye ne-nitrate okanye i-diitol phenol. Ukuze kuthintelwe ukubola kwezinto ezisisiseko), sebenzisa izixhobo (amanzi okusela, i-toothpaste, njl.njl.), izibulali-ntsholongwane, izibulali-zinambuzane, izigcini, njl.njl.

2. Isetyenziselwa ukuthintela ukubola kwamazinyo kunye nokubola komlomo xa kungekho fluoride emanzini emanzini;

3. Iidosi ezincinci zisetyenziswa ikakhulu kwi-osteoporosis kunye nesifo samathambo se-paget;

4. Ingasetyenziswa njengezinto ezikrwada okanye njengesixhobo sokufunxa i-fluoride kwenye i-fluoride okanye i-fluoride;

5. Ingasetyenziswa njenge-UF3 adsorbent kwiiarhente zonyango lwetyuwa ye-fluorine yesinyithi esikhanyayo, kwizixhobo zokunyibilikisa ityuwa, nakwimizi-mveliso yenyukliya;

6. Isisombululo sokuhlamba esenziwe ngentsimbi nezinye izinyithi, iiarhente ezidityanisiweyo kunye nee-welds;

7. Iiseramikhi, iglasi kunye nee-enamel melts kunye nee-shading agents, ii-ejenti zonyango lwesikhumba esiluhlaza kunye ne-epidermal kwishishini le-tone;

8. Yenza izikhuthazi ze-phosphate ekunyangweni komphezulu wesinyithi esimnyama ukuze kuzinziswe isisombululo se-phosphorative kwaye kuphuculwe ukusebenza kwe-membrane ye-phosphorus;

9. Njengesongezelelo kwimveliso yezinto zokutywina kunye nee-brake pads, idlala indima ekunyuseni ukumelana nokuguguleka;

10. Njengezongezo kwikhonkrithi, yonyusa ukumelana nokugqwala kwekhonkrithi.

Ukulumkela:

1. Sebenzisa i-sodium fluoride ukulawula ngokungqongqo ubungakanani be-fluorine imihla ngemihla ukuthintela ukuveliswa kwetyhefu ye-fluoride;

2. Isisombululo se-sodium fluoride okanye ijeli kufuneka ifakwe kwisikhongozeli seplastiki;

3. Izigulane, abafazi abakhulelweyo, abafazi abancancisayo, ukuthamba kwamathambo kunye nokungasebenzi kakuhle kwezintso kwiindawo ezine-fluoride eninzi akuvumelekanga.

Ukupakisha kunye nokugcina

Indlela yokupakisha:iingxowa zeplastiki okanye ingxowa yephepha enezikhumba ezimbini zeembombo iibharele zebhodi yefayibha yangaphandle, iibharele zeplywood, iibharele zebhodi yephepha eliqinileyo; iibharele zeplastiki (eziqinileyo) zangaphandle; iibharele zeplastiki (ezilulwelo); iileya ezimbini zeengxowa zeplastiki okanye ingxowa yeplastiki enezingqimba enye ngaphandle, ukuluka kweplastiki, ukuluka kweplastiki Iingxowa, iingxowa zelatex; ingxowa yeplastiki iingxowa zeplastiki ezidityanisiweyo ezilukiweyo (iingxowa zepolypropylene ezintathu-kwinye, iingxowa zepolyethylene ezintathu, iingxowa zepolypropylene ezimbini-kwinye, ingxowa yepolyethylene ezimbini-kwinye); iingxowa zeplastiki okanye iingxowa zephepha zesikhumba ezimbini-kwinye ngaphandle kwebhokisi yomthi eqhelekileyo; ibhotile yeglasi yentambo, ibhotile yeglasi yesiciko sesinyithi, ibhotile yeplastiki okanye ibharele yesinyithi (ithini) ibhokisi yomthi eqhelekileyo; ibhotile yeglasi yentambo, ibhotile yeplastiki okanye ithini egqunywe yipleyiti yesinyithi ebhityileyo (ithini) Ibhokisi, ibhokisi yefiberboard okanye ibhokisi yeplywood. Ukupakisha imveliso: 25kg/ibhegi.

Amanyathelo okhuseleko okugcina nokuthutha:Ngexesha lokuthuthwa koololiwe, itafile yokuhlanganisa imithwalo eyingozi kufuneka ifakwe ngokuhambelana neMithetho yoThutho lweMithwalo eyingozi yoMphathiswa wezoLoliwe. Ngaphambi kokuthuthwa, jonga ukuba isikhongozeli sokupakisha sigqityiwe kwaye sivaliwe na. Ngexesha lokuthuthwa, kufuneka siqinisekise ukuba isikhongozeli asifanele sivuze, sidilike, siwe, okanye sonakale. Akuvumelekanga ngokupheleleyo ukuxuba ne-asidi, i-oxidant, ukutya kunye nezongezo zokutya. Ngexesha lokuthuthwa, izithuthi zothutho kufuneka zixhotyiswe ngezixhobo zonyango olungxamisekileyo lokuvuza. Ngexesha lokuthuthwa, ukuvezwa lilanga kunye nemvula kufuneka kuvezwe ukuze kuthintelwe ubushushu obuphezulu. Gcina kwindawo yokugcina impahla epholileyo, eyomileyo, nengenamoya. Ubushushu bethala leencwadi abudluli kwi-30 ° C, kwaye ukufuma okufanelekileyo akudluli kwi-80%. Ukupakisha nokuvalela. Gcina ngokwahlukileyo kwiikhemikhali ze-asidi kunye nezityiwayo, kuphephe ukuxuba. Indawo yokugcina kufuneka ibe nezinto ezifanelekileyo zokulawula ukuvuza. Sebenzisa ngokungqongqo inkqubo yolawulo "lwe-five doubles" yezinto ezinobuthi.
