Ka ihe achọrọ n'ụwa niile maka ịdị mma gburugburu ebe obibi na nchekwa nke ihe ndị na-egbochi ire ọkụ na-abawanye, ụlọ ọrụ eriri na ákwà chọrọ ngwa ngwa ịchọpụta ihe ndị ọzọ maka ihe ndị na-egbochi ire ọkụ ọdịnala. Antimony trioxide (Sb₂O₃), dịka onye na-arụkọ ọrụ nke sistemụ ihe na-egbochi ire ọkụ halogen, achịọla ahịa ogologo oge. Ka o sina dị, nsí ya nwere ike ime, nhazi uzuzu, na esemokwu gburugburu ebe obibi emeela ka ụlọ ọrụ ahụ chọọ ngwọta ka mma. Site na njikwa mbupụ China na ihe ndị na-egbochi antimony, antimony trioxide dị ụkọ n'ahịa mba ụwa, sodium antimonate (NaSbO₃) adọtawo uche n'ihi ihe onwunwe kemịkalụ pụrụ iche ya na ọrụ nnọchi.

I. Ntụnyere usoro mgbochi ire ọkụ: mmetụta synergistic nke sodium antimonate na antimony trioxide
1. Usoro ihe mgbochi ọkụ nke Sb2O2 ọdịnala
Sb2O2 ga-arụkọ ọrụ na ihe ndị na-egbochi ọkụ halogen (dịka ihe ndị na-eme ka bromine dị n'ime ya). N'oge usoro ọkụ ahụ, ha abụọ na-emeghachi omume iji mepụta halides antimony na-agbanwe agbanwe (SbX2), nke na-egbochi ọkụ site na ụzọ ndị a:
ihe na-egbochi ọkụ nke oge gas: SbX₃ na-ejide radicals free (·H, ·OH) ma na-egbochi mmeghachi omume agbụ ígwè;
Ihe na-egbochi ire ọkụ nke nwere usoro condensed phase: na-akwalite mmepụta nke oyi akwa carbon iji kewapụ oxygen na okpomọkụ.
2. Àgwà sodium antimonate nke na-egbochi ire ọkụ
Nhazi kemịkalụ nke sodium antimonate (Na⁺ na SbO₃⁻) na-enye ya ọrụ abụọ:
Nkwụsi ike dị elu nke okpomọkụ: na-agbaze iji mepụta Sb₂O₃ na Na₂O na 300–500°C, Sb₂O₃ ewepụtara na-aga n'ihu na-arụkọ ọrụ na halogens maka igbochi ire ọkụ;
Mmetụta nke iwu alkaline: Na₂O nwere ike iwepụ gas acidic (dịka HCl) nke ọkụ na-emepụta ma belata nsị nke anwụrụ ọkụ.
Isi ihe dị mkpa gbasara teknụzụ: Sodium antimony na-ewepụta ụdị antimony na-arụ ọrụ site na ire ere, na-enweta mmetụta na-egbochi ire ọkụ nke yiri Sb2O₃ ma na-ebelata ihe ize ndụ nke ikpughe uzuzu n'oge nhazi.

II. Nyocha nke uru nke nnọchi sodium antimonate
1. Ebe obibi na nchekwa ka mma
Ihe ize ndụ dị ala nke uzuzu: Sodium antimonate dị na nhazi granular ma ọ bụ microspherical, ọ dịghịkwa mfe imepụta uzuzu a na-ekuru ume mgbe a na-ahazi ya;
Esemokwu gbasara nsí dị obere: Ma e jiri ya tụnyere Sb2O2 (nke EU REACH depụtara dị ka ihe nwere ike ịkpata nsogbu), sodium antimonate enweghị data nsí gburugburu ebe obibi ma a kabeghị achịkwa ya nke ọma.
2. Nhazi nhazi arụmọrụ
Mgbasa nke ọma: Aịọn sodium na-eme ka polarity dịkwuo elu, na-eme ka ọ dịrị mfe ịgbasa nke ọma na matriks polymer;
Ndakọrịta nke okpomọọkụ kwụsiri ike: Okpomọkụ ire ere na-adaba na okpomọkụ nhazi (200–300°C) nke eriri nkịtị (dịka polyester na naịlọn) iji zere ịda mbà n'oge.
3. Mmekọrịta dị iche iche
Ọrụ igbochi anwụrụ ọkụ: Na₂O na-eme ka gas acidic ghara ịdị mma ma na-ebelata nsí anwụrụ ọkụ (uru LOI nwere ike ịbawanye site na 2–3%);
Mgbochi ntapụ: Mgbe ejiri ihe ndị na-eme ka ihe na-adịghị mma (dịka ụrọ nano) jikọta ya, nhazi oyi akwa carbon na-adị oke njọ.
III. Ihe ịma aka ndị nwere ike ime n'iji Sodium Antimonate eme ihe
1. Nhazi n'etiti ọnụ ahịa na ojiji
Ọnụ ego akụrụngwa dị elu: Usoro mmepụta nke sodium antimonate dị mgbagwoju anya, ọnụ ahịa ya dịkwa ihe dị ka ugboro 1.2–1.5 nke Sb₂O₃;
Ọdịnaya antimony dị obere: N'okpuru otu ọkwa ihe na-egbochi ire ọkụ, a ga-amụba ọnụọgụ mgbakwunye site na 20-30% (n'ihi na ihe sodium na-ebelata mkpokọta antimony). Agbanyeghị, UrbanMines Tech. Ltd., yana uru pụrụ iche ya na nyocha na nhazi, nwere ike ime ka ọnụ ahịa mmepụta nke sodium antimonate dị ala karịa antimony trioxide ma buru ngwa ngwa buru ibu nke òkè ahịa ụwa n'ime ọkara afọ.
2. Nsogbu ndakọrịta teknụzụ
Mmetụta pH: Alkaline Na₂O nwere ike imetụta nkwụsi ike nke ụfọdụ resins (dịka PET);
Njikwa agba: Ihe fọdụrụ na sodium n'oge okpomọkụ dị elu nwere ike ime ka eriri ahụ nwee obere odo odo, nke chọrọ ka e tinye ihe na-acha agba.
3. A chọrọ ka a chọpụta ntụkwasị obi ogologo oge
Ọdịiche dị na iguzogide ihu igwe: Mbugharị ion sodium na gburugburu ebe ọkụ na iru mmiri nwere ike imetụta ike ire ọkụ;
Ihe ịma aka imegharị ihe: Usoro imegharị ihe maka eriri ndị na-egbochi ọkụ nwere sodium kwesịrị ịgbanwe.

IV. Ndụmọdụ gbasara ọnọdụ ngwa
Sodium antimonateọ kacha mma maka ubi ndị a:
1. Ákwà ndị bara uru nke ukwuu: dịka uwe ndị na-agba ọkụ na ime ụlọ ụgbọelu, nke nwere ihe achọrọ siri ike maka igbochi anwụrụ ọkụ na obere nsí;
2. Sistemụ mkpuchi mmiri: iji ohere nke mgbasa ya dochie nkwụsịtụ Sb₂O₃ mee ihe;
3. Usoro ihe eji egbochi ire ọkụ: ejiri ihe na-egbochi ire ọkụ phosphorus-nitrogen mee ka ọ dị mfe iji belata ịdabere na halogen.
