Sodium Fluoride

Sodium fluoride,waa nooc ka mid ah xarunta aan organic ahayn, qaacidada kiimikada waa NaF, inta badan loo isticmaalo warshadaha daahan sida dardar fosfat, cayayaanka beeraha, shaabadayn alaabta, preservatives iyo beeraha kale.

Qalabka Jirka:Cufnaanta qaraabada ah waa 2.558 (41/4 ​​° C), barta dhalaalidu waa 993 ° C, barta karkarinta waa 1695 ° C [1].(cufnaanta qaraabada 2.79, barta dhalaalka 992 ° C, barta karkarinta 1704 ° C [3]) Biyo ku milmay (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100g kiimikaad), ku milma acid hydrofluoric, iyo aan milmi karin. ethanol.Xalka aqueous waa alkaline (pH = 7.4).Sun (waxyeello habdhiska dareenka), LD50180mg/kg (jiirarka, afka), 5-10 garaam dhimasho.Guryaha: aan midab lahayn ama xitaa budada crystalline cad, ama kiristaalo cubic, kiristaalo fiican, oo aan lahayn ur.

Waxyaabaha kiimikaad:crystal dhalaalaya midab lahayn ama budo cad, habka tetragonal, leh kiristaalo hexahedral ama octahedral caadiga ah.Waxoogaa ku milma khamriga;Ku milmay biyaha, xal aqueous waa acidic, milmay ee hydrofluoric acid si ay u sameeyaan sodium hydrogen fluoride.

Codsiga:

1. Waxaa loo isticmaali karaa sida birta karbon sare leh, sida wakiilka hawo-celiya ee birta karkaraya, aluminium elektrolytic ah ama wakiilka dhalaaliyaha la safeeyey ee elektrolytka, daawaynta biyuhu ee warqadda, ilaalinta alwaax (oo leh sodium fluoride iyo nitrate ama diitol phenol -daxalka alaabta salka ah), isticmaalka alaabta (biyo cabbitaanka, daawada cadayga, iwm), jeermis dilaha, cayayaanka, ilaalinta, iwm.

2. Waxaa loo isticmaalaa si looga hortago suulista ilkaha iyo suulka afka ee la'aanta fluoride ee biyaha ku jira biyaha ku jira biyaha;

3. Qiyaaso yaryar ayaa inta badan loo isticmaalaa lafo-jileeca iyo cudurrada lafaha bogsashada;

4. Waxaa loo isticmaali karaa sida walxaha ceeriin ama fluoride nuuga ee fluoride kale;

5. Waxa loo isticmaali karaa sidii UF3 adsorbent ah ee birta khafiifka ah ee fluorine daawaynta milixda, dhalaalidda dhalaalaysa, iyo warshadaha nukliyeerka;

6. Xalka lagu dhaqo birta iyo biraha kale, walxaha alxanka leh iyo alxanka;

7. Ceramics, galaas iyo dhaldhalaalka dhalaala iyo wakiilada hadhka, maqaarka cayriin iyo wakiilada daawaynta epidermal ee warshadaha codka;

8. Samee dhiirrigeliyeyaasha fosfooraska ee daaweynta dusha sare ee birta madow si loo dejiyo xalka fosfooraska iyo hagaajinta waxqabadka xuubka fosfooraska;

9. Maaddaama wax lagu daro soo saarista alaabta lagu xidho iyo suufka biriiga, waxay door ka ciyaartaa caabbinta xirashada oo kordhay;

10. Sida waxyaabaha lagu daro shubka, xooji caabbinta daxalka ee shubka.

Ka taxadaritaan:

1. Isticmaal sodiyam fluoride si aad si adag u xakamayso qadarka fluorine maalin kasta si aad uga hortagto soo saarista sunta fluoride;

2. Sodium fluoride ama jel waa in lagu ridaa weel caag ah;

3. Bukaanka, haweenka uurka leh, haweenka nuujinaya, jilicsanaanta lafaha iyo kelyaha oo hawlgabka ah ee meelaha fluoride-ku ku badan yahay waa mamnuuc.
