ʻO ka Sodium Fluoride

ʻO ka sodium fluoride,He ʻano mea hoʻohui inorganic, ʻo NaF ka mea kemika, i hoʻohana nui ʻia i ka ʻoihana uhi e like me ka phosphating accelerator, ka lāʻau insecticide mahiʻai, nā mea hoʻopaʻa, preservatives a me nā māla ʻē aʻe.

Nā waiwai kino:ʻO 2.558 (41/4 ​​° C) ka mānoanoa pili, ʻo 993 ° C ka helu heheʻe, a ʻo 1695 ° C ka helu hoʻolapalapa [1]. (Maikaʻi pili 2.79, hehee wale 992 ° C, boiling point 1704 ° C [3]) Soluble i ka wai (15 ° C, 4.0g/100g; 25° C, 4.3g/100gchemicalbook), hiki ke hoʻoheheʻe ʻia i loko o ka hydrofluoric acid, a hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol. He alkaline ka hoʻonā wai (pH = 7.4). Toxic (hōʻino i ka ʻōnaehana nerve), LD50180mg/kg (iole, waha), 5-10 grams i ka make. Nā waiwai: ʻeleʻele a i ʻole keʻokeʻo keʻokeʻo pauka, a i ʻole nā ​​kristal cubic, nā kristal maikaʻi, me ka ʻala ʻole.

Nā waiwai kemika:ke aniani ʻālohilohi ʻole a i ʻole ka pauka keʻokeʻo, ʻōnaehana tetragonal, me nā kristal hexahedral mau a i ʻole octahedral mau. Hiki ke hoʻoheheʻe ʻia i ka waiʻona; Hiki ke hoʻoheheʻe ʻia i loko o ka wai, ʻakika ka hopena wai, hiki ke hoʻoheheʻe ʻia i ka waika hydrofluoric e hana ai i ka sodium hydrogen fluoride.

Noi:

1. Hiki ke hoʻohana 'ia e like me ke kila kiʻekiʻe -carbon, e like me ka ea -proof agent o ka paila kila, he alumini electrolytic a electrolytic hoʻoheheʻe 'ia mea hoʻoheheʻe 'ia, wai mālama 'ana o ka pepa, laau preservatives (me ka sodium fluoride a me ka nitrate a me ka diitol phenol No ka anti-corrosion o ka mea kumu), e hoʻohana i nā mea (wai inu, toothpaste, etc.), sterilides, etc.

2. Hoʻohana ʻia ia e pale i nā ʻili niho a me ka waha i ka nele o ka fluoride i ka wai i ka wai i ka wai;

3. Hoʻohana nui ʻia nā mea liʻiliʻi no ka osteoporosis a me ka maʻi iwi paget;

4. Hiki ke hoʻohana ʻia e like me ka mea maka a i ʻole fluoride absorbent o nā fluoride a i ʻole fluoride;

5. Hiki ke hoʻohana 'ia e like me ka UF3 adsorbent i ka malamalama metala fluorine paʻakai lapaʻau 'oihana, hooheheeia refiners, a me nukelea oihana;

6. Holoi holoi o ke kila a me nā metala ʻē aʻe, nā mea welded a me nā welds;

7. ʻO nā seramika, ke aniani a me ka enamel hehee a me nā mea pale, nā ʻili maka a me nā mea lapaʻau epidermal o ka ʻoihana leo;

8. E hana i nā mea hoʻolaha phosphate i ka mālama ʻana o ka metala ʻeleʻele e hoʻopaʻa i ka hopena phosphorurative a hoʻomaikaʻi i ka hana o ka membrane phosphorus;

9. Ma keʻano he mea hoʻohui i ka hanaʻana i nā mea hoʻopaʻa paʻa a me nā pad brake, hoʻokaniʻo ia i keʻano o ka hoʻonuiʻana i ke kū'ēʻana i ke kapa;

10. E like me nā mea hoʻohui i loko o ke kaʻa, e hoʻonui i ka pale ʻana i ka corrosion.

Nā mea e mālama ai:

1. E hoʻohana i ka sodium fluoride e hoʻomalu pono i ka nui o ka fluorine i kēlā me kēia lā e pale i ka hana ʻana o ka fluoride poisoning;

2. Pono e hoʻokomo ʻia ka solution sodium fluoride a i ʻole ka gel i loko o kahi pahu plastik;

3. ʻAʻole pāpā ʻia nā maʻi, nā wahine hāpai, nā wahine lactating, nā iwi palupalu a me ka hōʻole ʻole o ka renal ma nā wahi kiʻekiʻe-fluoride.

Hoʻopili a mālama

Keʻano hoʻopili:ʻeke ʻeke a i ʻole ʻeke pepa ʻili bipi ʻelua ʻāpana ʻāpana waho, barela plywood, barela papa pepa paʻa; nā ʻeke plastik (paʻa) ma waho o nā ʻeke plastik; nā pahu plastik (wai); ʻelua ʻāpana ʻeke ʻeke a i ʻole ʻeke ʻeke ʻeke hoʻokahi -layer waho ʻeke, ulana ʻilika ulana, ulana ʻilika ʻeke ʻeke, ʻeke latex; ʻeke ʻeke ʻeke i hoʻohui ʻia nā ʻeke i ulana ʻia (polypropylene ʻekolu-i-hoʻokahi ʻeke, polyethylene triple ʻeke, polypropylene ʻelua-i-hoʻokahi ʻeke, polyethylene ʻelua-i-hoʻokahi ʻeke); ʻeke ʻeke a i ʻole ʻeke pepa ʻili ʻelua ʻāpana ma waho o ka pahu lāʻau maʻamau; omole aniani milo, omole aniani uhi hao, omole plastik a i ole pahu metala (hiki) pahu laau ma'amau; ʻOmole aniani wiliwili, ʻōmole ʻilika a i ʻole pahu -plated thin steel plate barrel (can) Box, fiberboard box or plywood box.Product packaging: 25kg/bag.

ʻO ka mālama ʻana a me ka lawe ʻana:I ka wā o ke kaʻaahi kaʻaahi, pono e hoʻokomo ʻia ka papa ʻaina kaʻa pōʻino e like me ka Railway Ministry of Railways 'Dangerous Cargo Transportation Rules. Ma mua o ka lawe ʻana, e nānā inā paʻa a hoʻopaʻa ʻia ka pahu pahu. I ka wā o ka lawe ʻana, pono ia e hōʻoia ʻaʻole e kahe ka pahu, hāʻule, hāʻule, a pōʻino paha. Ua kapu loa ia e hui me ka waika, oxidant, meaʻai a me nā mea hoʻohui meaʻai. I ka wā o ka lawe ʻana, pono e hoʻolako ʻia nā kaʻa kaʻa me nā lako lapaʻau leakage. I ka wā o ka lawe ʻana, pono e ʻike ʻia ka lā a me ka ua e pale ai i ka wela kiʻekiʻe. E kūʻai i loko o kahi hale kūʻai maloʻo a maloʻo. ʻAʻole ʻoi aku ka mahana o ka waihona ma mua o 30 ° C, a ʻaʻole ʻoi aku ka haʻahaʻa haʻahaʻa ma mua o 80%. Hoʻopili a hoʻopaʻa ʻia. E kūʻai kaʻawale mai ka waika a me nā kemika hiki ke ʻai, e pale i ka hui ʻana. Pono e loaʻa i ka wahi mālama ka mea kūpono e loaʻa ai ka leakage. E hoʻokō pono i ka ʻōnaehana hoʻokele "ʻelima pālua" o nā mea ʻawaʻawa.
