Sodiyumu Fluoride

Sodiyumu fluoride,ni ubwoko bw'ibinyabutabire bitagira umwimerere, formula y'ibinyabutabire ni NaF, ikoreshwa cyane cyane mu nganda zikora irangi nk'umuvuduko wa fosfati, imiti yica udukoko mu buhinzi, ibikoresho byo gufunga, imiti irinda ubushyuhe n'ibindi.

Imiterere ifatika:Ubucucike bungana na 2.558 (41/4 ​​° C), aho gushonga ni 993 ° C, naho aho kubira ni 1695 ° C [1]. (Ubucucike bungana na 2.79, aho gushonga ni 992 ° C, aho kubira ni 1704 ° C [3]) Ishonga mu mazi (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100g chemicalbook), ishonga muri aside hydrofluoric, kandi ntishonga muri ethanol. Umuti w'amazi ni alkaline (pH = 7.4). Uburozi (bwangiza uturemangingo tw'imitsi), LD50180mg/kg (imbeba, inyobwa), garama 5-10 kugeza ku rupfu. Imiterere: ifu idafite ibara cyangwa yera ya crystalline, cyangwa crystals cube, crystals nziza, nta mpumuro.

Imiterere y'ibinyabutabire:Ifu y'umweru cyangwa iy'umweru idafite ibara, ifite ubwoko bwa tetragonal, ifite kristu zisanzwe za hexahedral cyangwa octahedral. Ishonga gato muri alcool; Ishonga mu mazi, ifite aside, ishonga muri aside hydrofluoric kugira ngo ikore sodium hydrogen fluoride.

Porogaramu:

1. Ishobora gukoreshwa nk'icyuma gifite karubone nyinshi, nk'icyuma kidahumeka mu byuma bishyuha, icyuma gishongesha cya aluminiyumu cyangwa electrolytic, uburyo bwo kuvura impapuro zidapfa amazi, imiti irinda kwangirika mu biti (irimo sodium fluoride na nitrate cyangwa diitol phenol). Kugira ngo urwanye kwangirika kw'ibikoresho by'ibanze, koresha ibikoresho (amazi yo kunywa, amenyo y'amenyo, nibindi), imiti igabanya ubukana, imiti yica udukoko, imiti irinda kwangirika, nibindi.

2. Ikoreshwa mu gukumira kurwara amenyo no kurwara mu kanwa mu gihe nta fluoride irimo mu mazi ari mu mazi;

3. Dose nto zikoreshwa cyane cyane mu kuvura indwara ya osteoporosis na paget bone disease;

4. Ishobora gukoreshwa nk'ibikoresho fatizo cyangwa nk'ikintu gikurura fluoride cy'indi fluoride cyangwa fluoride;

5. Ishobora gukoreshwa nk'umuyoboro wa UF3 mu bikoresho byo gutunganya umunyu wa fluorine mu byuma byoroheje, mu byuma bitunganya umunyu, no mu nganda za kirimbuzi;

6. Isukari yo gusukura ibyuma n'ibindi byuma, ibikoresho byo gusudira n'ibyo gusudira;

7. Ibumba, ikirahure n'ibintu bishonga kandi bigasiga uruhu, ibikoresho byo kuvura uruhu rudasaza n'iby'uruhu byo mu nganda zikora amabara atandukanye;

8. Gukora ibikoresho bitera fosfeti mu gutunganya hejuru y'icyuma cy'umukara kugira ngo bihamye umuti wa fosfeti kandi binoze imikorere ya fosfeti;

9. Nk'inyongera mu gukora ibikoresho byo gufunga no gufunga feri, bigira uruhare mu kongera ubushobozi bwo kwangirika;

10. Nk'inyongera muri sima, ongera imbaraga zo kurwanya ingese za sima.

Amabwiriza yo kwirinda:

1. Koresha sodium fluoride kugira ngo ugenzure neza ingano ya fluoride buri munsi kugira ngo wirinde ko fluoride yandura;

2. Umuti wa sodium fluoride cyangwa gel bigomba gushyirwa mu gikoresho cya pulasitiki;

3. Abarwayi, abagore batwite, abagore bonsa, koroha kw'amagufwa no kunanirwa kw'impyiko mu bice bifite fluoride nyinshi birabujijwe.

Gupakira no kubika

Uburyo bwo gupakira:imifuka ya pulasitiki cyangwa imifuka ibiri y'impapuro ifite uruhu rw'inka, imifuka ya fibre yo hanze, imifuka ya plywood, imifuka y'impapuro zikomeye; imifuka ya pulasitiki (ikomeye) hanze; imifuka ya pulasitiki (amazi); imifuka ibiri y'impapuro za pulasitiki cyangwa imifuka imwe y'impapuro zo hanze, imifuka ya pulasitiki, imifuka yo kuboha pulasitiki. Imifuka, imifuka ya latex; imifuka ya pulasitiki ifite imiterere ivanze (imifuka ya polipropylene itatu muri umwe, imifuka itatu ya polyethylene, imifuka ibiri muri umwe, polyethylene ibiri muri umwe); imifuka ya pulasitiki cyangwa imifuka ibiri y'impapuro z'uruhu hanze y'agasanduku k'imbaho ​​gasanzwe; icupa ry'ikirahure cy'ubudodo, icupa ry'ikirahure cy'icyuma, icupa rya pulasitiki cyangwa umufuka w'icyuma (agasanduku) agasanduku gasanzwe k'imbaho; icupa ry'ikirahure cy'ubudodo, icupa rya pulasitiki cyangwa icyuma gipfundikiye umufuka w'icyuma (agasanduku) Agasanduku, agasanduku k'ifibre cyangwa agasanduku ka plywood. Gupfunyika ibicuruzwa: 25kg/agasanduku.

Amabwiriza yo kwirinda mu kubika no gutwara:Mu gihe cyo gutwara abantu muri gari ya moshi, ameza yo guteranya imizigo iteje akaga agomba gushyirwaho hakurikijwe amabwiriza ya Minisiteri y’Imari ya Moshi agenga gutwara imizigo iteje akaga. Mbere yo gutwara abantu, reba niba agasanduku ko gupakira kuzuye kandi gafunze. Mu gihe cyo gutwara abantu, kagomba kugenzura ko agasanduku kadacika, katagwa, katagwa cyangwa ngo kangirike. Birabujijwe kuvanga na aside, okiside, ibiryo n’inyongeramusaruro. Mu gihe cyo gutwara abantu, imodoka zitwara abantu zigomba kuba zifite ibikoresho byo kuvura byihutirwa. Mu gihe cyo gutwara abantu, izuba n’imvura bigomba gushyirwa ahantu hakonje kandi hahumeka kugira ngo hirindwe ubushyuhe bwinshi. Bika ahantu hakonje, humutse kandi hahumeka umwuka. Ubushyuhe bw’isomero ntiburenze 30°C, kandi ubushuhe ntiburenze 80%. Bika ahantu hatandukanye n’aside n’imiti iribwa, wirinde kuvanga. Ahantu ho kubika hagomba kuba hari ibikoresho bikwiye kugira ngo habeho gufunga amazi. Shyira mu bikorwa gahunda yo gucunga ibintu by’uburozi ya "eshanu ebyiri".
