Sodium Fluoride

Sodium fluoride,ndi mtundu wa mankhwala osapangidwa, njira ya mankhwala ndi NaF, yomwe imagwiritsidwa ntchito makamaka mumakampani opaka utoto monga phosphoring accelerator, tizilombo taulimi, zida zotsekera, zosungira ndi zina.

Katundu Wachilengedwe:Kuchuluka kwa zinthu ndi 2.558 (41/4 ​​° C), kutentha kwa zinthu ndi 993 ° C, ndipo kutentha kwa zinthu ndi 1695 ° C [1]. (Kuchuluka kwa zinthu 2.79, kutentha kwa zinthu 992 ° C, kutentha kwa zinthu 1704 ° C [3]) Kusungunuka m'madzi (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100g chemicalbook), kusungunuka mu hydrofluoric acid, komanso kusasungunuka mu ethanol. Yankho lamadzi ndi alkaline (pH = 7.4). Poizoni (kuwononga mitsempha), LD50180mg/kg (mbewa, pakamwa), 5-10 magalamu mpaka kufa. Katundu: ufa wopanda utoto kapena woyera wa kristalo, kapena makhiristo a cubic, makhiristo abwino, opanda fungo.

Kapangidwe ka mankhwala:Krustalo wonyezimira kapena ufa woyera wopanda mtundu, dongosolo la tetragonal, wokhala ndi makristalo wamba a hexahedral kapena octahedral. Amasungunuka pang'ono mu mowa; Amasungunuka m'madzi, yankho lamadzi ndi acidic, amasungunuka mu hydrofluoric acid kuti apange sodium hydrogen fluoride.

Ntchito:

1. Ingagwiritsidwe ntchito ngati chitsulo chokhala ndi mpweya wambiri, monga choletsa mpweya ku chitsulo chowira, chosungunula cha aluminiyamu kapena choyeretsedwa cha electrolytic, chotsukira mapepala osalowa madzi, zosungira zamatabwa (zokhala ndi sodium fluoride ndi nitrate kapena diitol phenol. Kuti muchepetse dzimbiri pa zinthu zoyambira), gwiritsani ntchito zipangizo (madzi akumwa, mankhwala otsukira mano, ndi zina zotero), zoyeretsera, mankhwala ophera tizilombo, zosungira, ndi zina zotero.

2. Amagwiritsidwa ntchito poletsa kuonda kwa mano ndi kuonda kwa mkamwa chifukwa cha kusowa kwa fluoride m'madzi omwe ali m'madzi;

3. Mlingo wochepa umagwiritsidwa ntchito makamaka pa matenda a osteoporosis ndi matenda a mafupa a Paget;

4. Itha kugwiritsidwa ntchito ngati zinthu zopangira kapena zoyamwitsa fluoride ya fluoride kapena fluoride ina;

5. Itha kugwiritsidwa ntchito ngati chokometsera cha UF3 mu mankhwala ochepetsa mchere wa fluorine, makina oyeretsera, ndi mafakitale a nyukiliya;

6. Kutsuka kwachitsulo ndi zitsulo zina, zinthu zosungunula ndi zosungunula;

7. Zida zadothi, magalasi ndi enamel melts ndi shading, zochizira khungu losaphika ndi epidermal zamakampani opanga ma toni;

8. Pangani zolimbikitsira phosphate pochiza pamwamba pa chitsulo chakuda kuti mukhazikitse yankho la phosphorous ndikuwonjezera magwiridwe antchito a nembanemba ya phosphorous;

9. Monga chowonjezera pakupanga zinthu zotsekera ndi mabuleki, chimagwira ntchito yowonjezera kukana kuvala;

10. Monga zowonjezera mu konkire, onjezerani kukana dzimbiri kwa konkire.

Kusamalitsa:

1. Gwiritsani ntchito sodium fluoride kuti muwongolere kuchuluka kwa fluoride tsiku lililonse kuti mupewe poizoni wa fluoride;

2. Sodium fluoride solution kapena gel ziyenera kuyikidwa mu chidebe cha pulasitiki;

3. Odwala, amayi apakati, amayi oyamwitsa, kufewa kwa mafupa ndi kulephera kwa impso m'malo okhala ndi fluoride yambiri ndi oletsedwa.

Kulongedza ndi kusunga

Njira yopangira zinthu:Matumba apulasitiki kapena thumba la pepala la chikopa cha ng'ombe la magawo awiri, mabotolo akunja a ulusi, mabotolo a plywood, mabotolo a pepala lolimba; mabotolo apulasitiki (olimba) akunja; mabotolo apulasitiki (amadzimadzi); zigawo ziwiri za matumba apulasitiki kapena thumba la pulasitiki la gawo limodzi, kuluka kwa pulasitiki, kulukira kwa pulasitiki Matumba, matumba a latex; thumba la pulasitiki matumba opangidwa ndi pulasitiki (matumba atatu mu imodzi, matumba atatu a polyethylene, matumba awiri mu imodzi, thumba la polyethylene awiri mu imodzi); matumba apulasitiki kapena matumba a pepala lachikopa awiri mu zigawo ziwiri kunja kwa bokosi lamatabwa wamba; botolo lagalasi la ulusi, botolo lagalasi losindikizira lachitsulo, botolo la pulasitiki kapena mbiya yachitsulo (chitini) bokosi lamatabwa wamba; botolo lagalasi la ulusi, botolo la pulasitiki kapena tini -yokutidwa ndi mbale yachitsulo yopyapyala (chitini) Bokosi, bokosi la fiberboard kapena bokosi la plywood. Kupaka kwazinthu: 25kg/thumba.

Malangizo Osungira ndi Kunyamula:Pa nthawi yoyendera sitima, tebulo loyika katundu woopsa liyenera kukhazikitsidwa motsatira Malamulo a Unduna wa Njanji a Kuyendera Katundu Woopsa. Musanayendetse, yang'anani ngati chidebe chonyamula katundu chatha ndipo chatsekedwa. Pa nthawi yoyendera, chiyenera kuonetsetsa kuti chidebecho sichikutuluka madzi, kugwa, kugwa, kapena kuwonongeka. N'koletsedwa kusakaniza ndi asidi, okosijeni, chakudya ndi zowonjezera zakudya. Pa nthawi yoyendera, magalimoto oyendera ayenera kukhala ndi zida zochizira zadzidzidzi zotayikira. Pa nthawi yoyendera, kutentha kwa dzuwa ndi mvula ziyenera kuyikidwa pa malo osungiramo zinthu kuti zisatenthe kwambiri. Sungani m'nyumba yosungiramo zinthu yozizira, youma, komanso yopuma mpweya. Kutentha kwa laibulale sikuyenera kupitirira 30 ° C, ndipo chinyezi sichiyenera kupitirira 80%. Kuyika ndi kutseka. Sungani padera ndi mankhwala ophera asidi ndi zakudya, pewani kusakaniza. Malo osungiramo zinthu ayenera kukhala ndi zinthu zoyenera kuti zisunge kutayikira. Gwiritsani ntchito mosamala njira yoyang'anira zinthu zapoizoni ya "five doubles".
