Sodium fluoride,he ʻano hui inorganic, ʻo ke ʻano kemika ʻo NaF, i hoʻohana nui ʻia i ka ʻoihana uhi e like me ka phosphating accelerator, insecticide mahiʻai, nā mea sila, nā mea mālama a me nā mahina ʻē aʻe.
Nā Waiwai Kino:ʻO ka nui o ka mea hoʻohuihui he 2.558 (41/4 ° C), ʻo ke kiko heheʻe he 993 ° C, a ʻo ke kiko paila he 1695 ° C [1]. (ʻO ka nui o ka mea hoʻohuihui he 2.79, ke kiko heheʻe 992 ° C, ke kiko paila 1704 ° C [3]) Hiki ke hoʻoheheʻe ʻia i ka wai (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100g kemika), hiki ke hoʻoheheʻe ʻia i ka waikawa hydrofluoric, a hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol. He alkaline ka hopena wai (pH = 7.4). ʻAihue (hōʻino i ka ʻōnaehana nerve), LD50180mg/kg (ʻiole, waha), 5-10 gram a make. Nā waiwai: pauka crystalline kala ʻole a keʻokeʻo paha, a i ʻole nā kristal cubic, nā kristal maikaʻi, me ka ʻala ʻole.
Nā waiwai kemika:kristal ʻālohilohi kala ʻole a pauka keʻokeʻo paha, ʻōnaehana tetragonal, me nā kristal hexahedral maʻamau a i ʻole octahedral. Hoʻoheheʻe iki ʻia i ka waiʻona; Hoʻoheheʻe ʻia i ka wai, he waikawa ka hopena wai, hoʻoheheʻe ʻia i ka waikawa hydrofluoric e hana i ka sodium hydrogen fluoride.
Noi:
1. Hiki ke hoʻohana ʻia e like me ke kila kalapona kiʻekiʻe, e like me ka mea pale ea o ke kila paila, kahi mea hoʻoheheʻe electrolytic alumini a i ʻole electrolytic i hoʻomaʻemaʻe ʻia, ka mālama ʻana i ka pepa me ka wai ʻole, nā mea mālama lāʻau (me ka sodium fluoride a me ka nitrate a i ʻole diitol phenol No ka pale ʻana i ka palaho o ke kumu), hoʻohana i nā mea (wai inu, toothpaste, a pēlā aku), nā sterilizers, nā insecticides, nā mea mālama, a pēlā aku.
2. Hoʻohana ʻia e pale aku i nā caries niho a me nā caries waha i ka nele o ka fluoride i loko o ka wai i loko o ka wai;
3. Hoʻohana nui ʻia nā mahele liʻiliʻi no ka osteoporosis a me ka maʻi iwi paget;
4. Hiki ke hoʻohana ʻia ma ke ʻano he mea maka a i ʻole ka mea hoʻomoʻa fluoride o nā fluoride a i ʻole fluoride ʻē aʻe;
5. Hiki ke hoʻohana ʻia ma ke ʻano he adsorbent UF3 i nā mea mālama paʻakai fluorine metala māmā, nā mea hoʻomaʻemaʻe hoʻoheheʻe, a me nā ʻoihana nukelea;
6. Hoʻoheheʻe holoi o ke kila a me nā metala ʻē aʻe, nā mea hoʻopili a me nā mea hoʻopili;
7. Nā keramika, aniani a me ka enamel heheʻe a me nā mea hoʻomalu malu, ka ʻili maka a me nā mea mālama epidermal o ka ʻoihana leo;
8. Hana i nā mea hoʻolaha phosphate i ka mālama ʻana i ka ʻili o ka metala ʻeleʻele e hoʻopaʻa i ka hopena phosphorurative a hoʻomaikaʻi i ka hana o ka membrane phosphorus;
9. Ma ke ʻano he mea hoʻohui i ka hana ʻana o nā mea sila a me nā pads brake, he kuleana kona i ka hoʻonui ʻana i ke kūpaʻa ʻana o ka ʻaʻahu;
10. Ma ke ʻano he mau mea hoʻohui i loko o ka sima, hoʻoikaika i ke kūpale ʻana i ka pala o ka sima.
Nā Mālama:
1. E hoʻohana i ka sodium fluoride e kāohi pono i ka nui o ka fluorine i kēlā me kēia lā e pale ai i ka hana ʻana o ka lāʻau make fluoride;
2. Pono e waiho ʻia ka wai sodium fluoride a i ʻole ka gel i loko o kahi pahu plastik;
3. Ua pāpā ʻia nā maʻi, nā wahine hāpai, nā wahine hānai, ka palupalu o ka iwi a me ka hāʻule ʻana o ka puʻupaʻa ma nā wahi kiʻekiʻe -fluoride.
Hoʻopili a me ka mālama ʻana
ʻAno hoʻopili:ʻeke palaki a i ʻole ʻeke pepa ʻili bipi ʻelua papa nā barela papa fiber waho, nā barela plywood, nā barela papa pepa paʻakikī; nā barela palaki (paʻa) ma waho o nā ʻeke palaki; nā barela palaki (wai); ʻelua papa o nā ʻeke palaki a i ʻole ʻeke palaki hoʻokahi papa ma waho o nā ʻeke, ulana palaki ulana, ulana palaki ulana ʻeke, ʻeke latex; ʻeke palaki nā ʻeke ulana palaki hui (ʻeke polypropylene ʻekolu-i-hoʻokahi, ʻeke polyethylene ʻekolu, ʻeke polypropylene ʻelua-i-hoʻokahi, ʻeke polyethylene ʻelua-i-hoʻokahi); nā ʻeke palaki a i ʻole ʻeke pepa ʻili ʻelua-papa ma waho Pahu lāʻau maʻamau; ʻōmole aniani kaula, ʻōmole aniani paʻi uhi hao, ʻōmole palaki a i ʻole pahu metala (kini) pahu lāʻau maʻamau; ʻōmole aniani kaula, ʻōmole palaki a i ʻole pahu kila lahilahi i uhi ʻia me ka tini (kini) Pahu, pahu fiberboard a i ʻole pahu plywood. Hoʻopili huahana: 25kg/ʻeke.
Nā ʻōlelo aʻoaʻo no ka mālama ʻana a me ka lawe ʻana:I ka wā o ka halihali kaʻaahi, pono e hoʻokomo ʻia ka papa ʻaha ukana weliweli e like me nā Rula Hoʻoili Ukana Pōʻino o ke Kuhina Kaʻaahi o nā Kaʻaahi. Ma mua o ka halihali ʻana, e nānā inā ua piha a paʻa ka pahu hoʻopili. I ka wā o ka halihali ʻana, pono e hōʻoia ʻaʻole e liki, hiolo, hāʻule, a hōʻino paha ka pahu. Kapu loa ke kāwili ʻana me ka waikawa, ka mea hoʻoheheʻe, ka meaʻai a me nā mea hoʻohui meaʻai. I ka wā o ka halihali ʻana, pono e hoʻolako ʻia nā kaʻa halihali me nā lako hana lapaʻau ulia pōpilikia liki. I ka wā o ka halihali ʻana, pono e hōʻike ʻia ka lā a me ka ua e pale aku i ke kiʻekiʻe o ka mahana. E mālama i loko o kahi hale waihona meaʻai anuanu, maloʻo, a me ka ea. ʻAʻole ʻoi aku ka mahana o ka hale waihona puke ma mua o 30 ° C, a ʻaʻole ʻoi aku ka haʻahaʻa ma mua o 80%. Hoʻopili a paʻa. E mālama kaʻawale mai nā kemika waikawa a me nā mea ʻai, e pale i ka kāwili ʻana. Pono ka wahi mālama i nā mea kūpono e paʻa ai ka liki. E hoʻokō pono i ka ʻōnaehana hoʻokele "ʻelima pālua" o nā mea ʻawahia.
