Onye nrụpụta ezigbo ọnụ ahịa sodium fluoride CAS: 7681-49-4

sodium fluoride; NAF; SF; Fluoride inorganic, ọ bụ kristal na-enweghị agba ma ọ bụ ntụ ntụ na-egbuke egbuke, bụ nke sistem tetragonal, bụ kristal hexahedral ma ọ bụ octahedral dị mma. Ọ bụ ntakịrị soluble na mmanya, soluble na mmiri. Aqueous ngwọta bụ acidic. Ọ na-agbaze na hydrofluoric acid iji mepụta sodium hydrogen fluoride.
1. Sodium fluoride bụ tumadi ji dị ka Inlaid ígwè maka n'ibu agụba na planer welie weld ike. Nke abuo, a na-eji ya dị ka ihe nchekwa osisi, fungicides na ụlọ ọrụ mmepụta ihe, ọgwụ pesticides na-arụ ọrụ ugbo (kwesịrị ibute na-acha anụnụ anụnụ), ihe nchekwa ahụike, ịgbado ọkụ ọkụ, onye na-ahụ maka fluorine maka mmiri ọṅụṅụ. A na-ejikwa ya maka imepụta fluoride ndị ọzọ na casein gluu, sodium fluoride ntacha eze, dị ka adhesives, nke a na-ejikwa na akwụkwọ na ụlọ ọrụ ọla. N'ime mmepụta nke elemental fluorine, a na-eji ya wepụ ihe nchịkọta nke hydrogen fluoride. Na mgbakwunye, a na-ejikwa ya na enamels na ụlọ ọrụ ọgwụ.
2. A na-eji sodium fluoride mee ihe dị ka ihe na-egbu egbu, ihe nchekwa, ọgwụ pesticides, na-ejikwa enamel, nchekwa osisi, ọgwụ, metallurgy, mmepụta nke fluorides na ihe ndị ọzọ.
3. A na-eji maka mkpebi siri ike nke scandium na microanalysis, mkpebi nke phosphorus na nyocha nke photoelectric colorimetric, nke a na-eji dị ka reagent, ndị na-ekpuchi ihe mkpuchi, ihe nchekwa nke ígwè na ígwè.
4. Dị ka ihe mgbakwunye nri. Dị ka iwu ndị China maka nnu si dị, ihe kacha eji eme ihe bụ 0.1g/kg.
5. Ọ na-eji dị ka osisi preservatives, pharmaceutical preservative, ịgbado ọkụ flux na-eji na akwụkwọ ụlọ ọrụ, nke a ụlọ ọrụ ngwaahịa bụ kpọmkwem larịị toothpastes, nwekwara ike-eji dị ka ọcha gị n'ụlọnga maka mmiri ọṅụṅụ, na-eji maka hides na akpụkpọ nhazi na tanning ụlọ ọrụ, n'ihi na agbaze na refining nke ìhè metal, na nchebe oyi akwa nke ìhè metal, n'ihi na adhesive corrosion ígwè.
6. A na-eji sodium fluoride mee ihe dị ka onye na-eme ngwa ngwa Phosphate na ụlọ ọrụ mkpuchi, na-eme ka ngwọta phosphating kwụsie ike, nhazi phosphate, na-eme ka ọrụ nke mkpuchi phosphate dịkwuo mma. Aluminom na alloys phosphate nwere ike mechie catalytic Al3 + nke nnukwu ihe egwu, ma mee ka phosphating were were were. A na-eji ya dị ka ihe nchekwa osisi, pesticides ugbo, fungicides na ụlọ ọrụ mmepụta ihe, ihe nchekwa ọgwụ, ịgbado ọkụ, ihe mgbakwunye zinc zincate zinc na enamel, akwụkwọ na ihe ndị ọzọ.
