Nhanganyaya
Sezvo zvinodiwa pasi rose zvekuchengetedza nharaunda uye kuchengetedzeka kwezvinhu zvinodzivirira moto zvichiwedzera, indasitiri yefaibha nemachira inofanira kutsvaga dzimwe nzira dzekushandisa zvinodzora moto zvechinyakare. Antimony trioxide (Sb₂O₃), semubatsiri mukuru wehurongwa hwe halogen fire retardant, yagara ichitonga musika. Kunyange zvakadaro, chepfu yayo inogona kuitika, njodzi dzekugadzirisa guruva, uye gakava rezvakatipoteredza zvakaita kuti indasitiri iyi itsvage mhinduro dziri nani. Nekudzora kweChina kunze kwenyika pamakemikari e antimony, antimony trioxide haiwanikwe mumusika wepasi rose, uye sodium antimonate (NaSbO₃) yakakwezva kutariswa nekuda kwehunhu hwayo hwemakemikari akasiyana uye mabasa ekutsiva. Chikwata chehunyanzvi cheUrbanMines Tech. Ltd., pamwe chete neruzivo rwekushandisa chaiko uye nyaya dzekutsiva sodium antimonate, chakaunganidza chinyorwa ichi kubva pamaonero ehunyanzvi, chakakurukura nevanhu vane ruzivo muindasitiri iyi nezvekugona kwe sodium antimonate kutsiva Sb₂O₃, uye chakaongorora misimboti yayo zvakanakira, uye zvayakaipira.

I. Kuenzanisa kwenzira dzinodzora moto: mhedzisiro yekubatana kwe sodium antimonate uye antimony trioxide
1. Muchina unodzora moto weSb2O2 yechinyakare
Sb2O2 inofanira kushanda pamwe chete ne halogen flame retardants (senge bromine compounds). Munguva yekupiswa, zviviri izvi zvinogadzira volatile antimony halides (SbX2), iyo inodzivisa kupisa kuburikidza nenzira dzinotevera:
Chinodzora moto wechikamu chegasi: SbX₃ inobata mafree radicals (·H, ·OH) uye inomisa maitiro echain;
Murazvo unodzorwa nechikamu chemukoto: unokurudzira kuumbwa kwechikamu chekabhoni kuti uparadzanise okisijeni nekupisa.
2. Hunhu hwe sodium antimonate hunodzora moto
Maumbirwo emakemikari e sodium antimonate (Na⁺ neSbO₃⁻) anoita kuti ive nemabasa maviri:
Kugadzikana kwekupisa kwakanyanya: inoora kuti igadzire Sb₂O₃ naNa₂O pa300–500°C, uye Sb₂O₃ inoburitswa inoramba ichishanda pamwe chete nema halogens ekudzivirira moto;
Kudzora kweAlkaline: Na₂O inogona kudzima magasi ane acidic (akadai seHCl) anogadzirwa nekutsva uye kuderedza kukora kweutsi.
Pfungwa huru dzehunyanzvi: Sodium antimony inoburitsa mhando dzeantimony dzinoshanda nekuora, zvichiita kuti pave nemhedzisiro inodzivisa moto yakaenzana neSb2O₃ uku ichideredza njodzi yekusangana neguruva panguva yekugadzirisa.

II. Kuongororwa kwezvakanaka zvekutsiva sodium antimonate
1. Nzvimbo yakavandudzwa uye kuchengetedzeka
Njodzi shoma yeguruva: Sodium antimonate iri muchimiro chegranular kana microspherical, uye hazvisi nyore kugadzira guruva rinofemereka panguva yekugadzirisa;
Kusawirirana kwechepfu: Kana tichienzanisa neSb2O2 (yakanyorwa sechinhu chinogona kukonzera kuzvidya mwoyo neEU REACH), sodium antimonate haina data rechepfu hwezvakatipoteredza uye haisati yatongwa zvakasimba.
2. Kugadzirisa mashandiro ekugadzirisa
Kupararira kwakawedzerwa: Maion eSodium anowedzera polarity, zvichiita kuti zvive nyore kupararira zvakaenzana mupolymer matrix;
Kuenzanisa kugadzikana kwekupisa: Kupisa kwekuora kunoenderana nekupisa kwekugadzirisa (200–300°C) kwemafiber akajairika (akadai sepolyester nenylon) kudzivirira kutadza kushanda zvakanaka nguva isati yakwana.
3. Kubatana kwemabasa akawanda
Basa rekudzora utsi: Na₂O inobvisa magasi ane acid uye inoderedza chepfu yeutsi (kukosha kweLOI kunogona kuwedzerwa ne2–3%);
Kudzivirira kudonha kwemvura: Kana zvikabatanidzwa nezvinhu zvisina kugadzirwa (zvakaita sevhu re nano), chimiro chekabhoni chinova chakaoma.
III. Matambudziko Angangoitika Pakushandiswa kweSodium Antimonate
1. Kuenzana pakati pemutengo nekushandiswa
Mutengo wepamusoro wezvinhu zvakabikwa: Maitiro ekugadzira sodium antimonate akaoma uye mutengo wacho wakapetwa ka1.2–1.5 kupfuura weSb₂O₃;
Kuwanda kweantimony kusingashande zvakanaka: Pasi pehuwandu hwakafanana hwemurazvo unodzivirira moto, huwandu hwekuwedzera hunofanirwa kuwedzerwa ne20-30% (nekuti sodium element inoderedza huwandu hweantimony). Zvisinei, UrbanMines Tech. Ltd., ine zvayakanakira zvakasiyana nezveR&D, inogona kuwedzera mutengo wekugadzira sodium antimonate kuti ive yakaderera pane antimony trioxide uye nekukurumidza kutora chikamu chikuru chemusika wepasi rose mukati mehafu yegore.
2. Matambudziko ekushanda kwehunyanzvi
Kunzwa kwepH: Alkaline Na₂O inogona kukanganisa kugadzikana kwekunyunguduka kwemamwe maresini (akadai sePET);
Kudzora Hue: Zvisaririra zveSodium pakupisa kwakanyanya zvinogona kukonzera yero diki yefiber, zvichida kuwedzerwa madhayi.
3. Kuvimbika kwenguva refu kunofanirwa kusimbiswa
Musiyano mukuramba kwemamiriro ekunze: Kufamba kweSodium ion munzvimbo dzinopisa uye dzine hunyoro kunogona kukanganisa kugara kwenguva refu kwemoto;
Matambudziko ekugadzirisazve: Maitiro ekugadzirisazve makemikari emafiber ane sodium anodzivirira moto anofanira kugadziriswazve.

IV. Mazano ekushandisa
Sodium antimonateyakakodzera minda inotevera:
1. Machira ane kukosha kwakanyanya: akadai semayunifomu ekudzimisa moto nemidziyo yendege, ane zvinodiwa zvakasimba pakuderedza utsi uye chepfu shoma;
2. Sisitimu yekuputira inobva mumvura: kushandisa mukana wekupararira kwayo kutsiva kusungirirwa kweSb₂O₃;
3. Fomura inosanganisa murazvo: inosanganiswa ne phosphorus-nitrogen murazvo zvinoderedza kutsamira kwe halogen.

V. Mirayiridzo Yekutsvagisa Yeramangwana
1. Kugadziriswa kweNano: Kuvandudza kushanda kwemurazvo unodzora moto nekudzora saizi yezvikamu (<100 nm);
2. Musanganiswa wekutakura zvinhu unobva kuBio-based: wakasanganiswa ne cellulose kana chitosan kugadzira fibers dzegirini dzinodzivirira moto;
3. Kuongorora Kutenderera Kwehupenyu (LCA): Kuyera mabhenefiti ezvakatipoteredza echikamu chose cheindasitiri.

Mhedziso
Senzira inogona kutsiva antimony trioxide, sodium antimonate inoratidza kukosha kwakasiyana maererano nekuchengetedza nharaunda uye kushanda kwayo, asi mutengo wayo uye kugona kwayo kushanduka-shanduka kuchiri kuda kuvandudzwa. Nemitemo yakaoma uye kugadzirisa maitiro, sodium antimonate inotarisirwa kuva sarudzo yakakosha kuchizvarwa chinotevera chefiber flame retardants, zvichiita kuti indasitiri ishandukire kuenda pakushanda zvakanyanya uye kuderera kwechepfu.
