Mea Hana Kumukūʻai Maikaʻi Sodium fluoride CAS:7681-49-4

ʻO ka Sodium fluoride; NaF；SF; Inorganic Fluoride, he mau kristal kala ʻole a i ʻole ka pauka keʻokeʻo ʻālohilohi, no ka ʻōnaehana tetragonal, he mau kristal hexahedral maikaʻi a i ʻole octahedral. He mea hoʻoheheʻe iki ia i ka waiʻona, hiki ke hoʻoheheʻe ʻia i ka wai. He waikawa ka hopena wai. Hoʻoheheʻe ia i loko o ka waikawa hydrofluoric e hana i ka sodium hydrogen fluoride.
1. Hoʻohana nui ʻia ka sodium fluoride ma ke ʻano he kila Inlaid no ka pahi mechanical a me ka planer e hoʻoikaika i ka ikaika weld. ʻO ka lua, hoʻohana ʻia ia ma ke ʻano he mea mālama lāʻau, fungicides i ka ʻoihana hana pia, nā pesticides mahiʻai (pono e hoʻopili ʻia me ka uliuli), nā mea mālama lapaʻau, ka flux welding, ka mea fluorine no ka wai inu. Hoʻohana pū ʻia no ka hana ʻana i nā fluoride ʻē aʻe a me ka casein glue, sodium fluoride toothpaste, ma ke ʻano he mea hoʻopili, hoʻohana pū ʻia i nā ʻoihana pepa a me nā metallurgical. I ka hana ʻana o ka fluorine elemental, hoʻohana ʻia ia no ka wehe ʻana i nā nui o ka hydrogen fluoride. Eia kekahi, hoʻohana ʻia ia i nā enamels a me nā ʻoihana lāʻau lapaʻau.
2. Hoʻohana ʻia ka sodium fluoride ma ke ʻano he disinfectants, preservatives, pesticides, hoʻohana ʻia hoʻi i ka enamel, ka mālama ʻana i ka lāʻau, ka lāʻau lapaʻau, ka metallurgy, ka hana ʻana o nā fluorides a pēlā aku.
3. Hoʻohana ʻia no ka hoʻoholo ʻana o ka scandium i ka microanalysis, ka hoʻoholo ʻana o ka phosphorus i ka loiloi colorimetric photoelectric, hoʻohana ʻia e like me ka reagent, nā mea masking, nā mea mālama o ka hao a me ke kila.
4. Ma ke ʻano he mea hoʻohui meaʻai. Wahi a nā lula Kina no ka paʻakai, ʻo ka hoʻohana nui loa he 0.1g/kg.
5. Hoʻohana ʻia ia ma ke ʻano he mea mālama lāʻau, mea mālama lāʻau lapaʻau, hoʻoheheʻe ʻana i ka flux a hoʻohana ʻia i ka ʻoihana pepa, ʻo nā huahana a kēia hui he mau toothpaste pae kikoʻī, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe no ka wai inu, a hoʻohana ʻia no nā ʻili a me ka hana ʻili i ka ʻoihana tanning, no ka hoʻoheheʻe ʻana a me ka hoʻomaʻemaʻe ʻana i ka metala māmā, a me ka papa pale o ka metala māmā, no ka palaho pipili, a me ka hana ʻana i ke kila paila.
6. Hoʻohana ʻia ka sodium fluoride ma ke ʻano he mea hoʻolalelale Phosphate i ka ʻoihana uhi, e hana i ka paʻa o ka hopena phosphating, hoʻomaʻemaʻe phosphate, hoʻomaikaʻi i ka hana o ka uhi phosphate. Hiki i ka alumini a me kāna mau phosphate alloys ke pani i ka catalytic Al3 + maikaʻi ʻole o ka pōʻino nui, a hana i ka phosphating maʻalahi. Hoʻohana ʻia ia ma ke ʻano he mea mālama lāʻau, nā pesticides mahiʻai, nā fungicides i ka ʻoihana hana pia, nā mea mālama lāʻau lapaʻau, ka flux welding, nā mea hoʻohui zincate alkaline a me ka enamel, pepa a pēlā aku.
