Hordhac
Maadaama shuruudaha caalamiga ah ee saaxiibtinimoda deegaanka iyo badbaadada agabka ka hortagga dabka ay sii kordhayaan, warshadaha fiber-ka iyo dharka ayaa si degdeg ah ugu baahan inay sahamiyaan beddelaadaha ka hortagga dabka dhaqameed. Antimony trioxide (Sb₂O₃), oo ah isku-duwaha ugu muhiimsan ee nidaamyada ka hortagga dabka halogen, ayaa muddo dheer gacanta ku hayay suuqa. Si kastaba ha ahaatee, sunta suurtagalka ah, habaynta khataraha boodhka, iyo khilaafaadka deegaanka ayaa ku kallifay warshadaha inay raadiyaan xalal ka wanaagsan. Iyada oo la xakameynayo dhoofinta Shiinaha ee isku-dhafka antimony, antimony trioxide ayaa ku yar suuqa caalamiga ah, sodium antimonate (NaSbO₃) waxay soo jiidatay dareenka sababtoo ah sifooyinka kiimikada ee gaarka ah iyo shaqooyinka beddelka. Kooxda farsamada ee UrbanMines Tech. Ltd., oo ay weheliso khibradda isticmaalka dhabta ah iyo kiisaska beddelka sodium antimonate, waxay soo ururiyeen maqaalkan aragti farsamo, iyagoo ka wada hadlay dadka aqoonta u leh warshadaha suurtagalnimada sodium antimonate oo beddelaya Sb₂O₃, waxayna falanqeeyeen mabaadi'deeda faa'iidooyinka, iyo khasaarooyinka.

I. Isbarbardhigga farsamooyinka ka hortagga dabka: saamaynta isku-dhafka ah ee sodium antimonate iyo antimony trioxide
1. Habka dib u celinta ololka ee Sb2O2 dhaqameed
Sb2O2 waa inuu si isku mid ah ula shaqeeyaa waxyaabaha halogeenka ololka ka celiya (sida isku-dhafka bromine). Inta lagu jiro habka gubashada, labaduba waxay ka falceliyaan sameynta halides-ka antimony-ga ee kacsan (SbX2), kuwaas oo joojiya gubashada iyada oo loo marayo waddooyinka soo socda:
Dawada dabka ee wejiga gaaska: SbX₃ waxay qabataa xagjirrada xorta ah (·H, ·OH) waxayna joojisaa falcelinta silsiladda;
Dareeraha dabka ee wejiga isku dhafan: wuxuu kor u qaadaa sameynta lakabka kaarboon si loo kala saaro oksijiinta iyo kulaylka.
2. Sifooyinka ka hortagga ololka ee sodium antimonate
Qaab-dhismeedka kiimikada ee sodium antimonate (Na⁺ iyo SbO₃⁻) wuxuu siinayaa shaqo labanlaab ah:
Xasillooni heerkul sare: waxay burburisaa si ay u soo saarto Sb₂O₃ iyo Na₂O₃ heerkul ah 300–500°C, Sb₂O₃ oo la sii daayayna waxay sii waddaa inay la shaqeyso halogens-ka si loo yareeyo ololka;
Saamaynta xakamaynta alkaline: Na₂O waxay dhexdhexaadin kartaa gaasaska aashitada leh (sida HCl) ee uu soo saaro gubashada waxayna yareyn kartaa daxalka qiiqa.
Qodobbada farsamada muhiimka ah: Sodium antimony waxay sii deysaa noocyada antimony firfircoon iyagoo kala daadanaya, iyagoo gaaraya saameyn dab-celin ah oo u dhiganta Sb2O₃ iyadoo la dhimayo khatarta soo-gaadhista boodhka inta lagu jiro farsamaynta.

II. Falanqaynta faa'iidooyinka beddelka sodium antimonate
1. Deegaan iyo badbaado oo la hagaajiyay
Khatar Boodh Yar: Sodium antimonate wuxuu ku jiraa qaab-dhismeed dhagax ah ama microsferical ah, mana fududa in la soo saaro boodh la neefsan karo inta lagu jiro farsamaynta;
Muran yar oo sun ah: Marka la barbardhigo Sb2O2 (oo loo taxay inay tahay walax walaac leh oo ay leedahay EU REACH), sodium antimonate waxay leedahay xog sun ah oo deegaanka ah oo yar, weli si adag looma nidaamin.
2. Hagaajinta waxqabadka
Kala firdhis la xoojiyay: Aayooyinka soodhiyamku waxay kordhiyaan kala firdhisnaanta, taasoo sahlaysa in si siman loogu kala firdhiyo matrix-ka polymer-ka;
Iswaafajinta xasilloonida kulaylka: Heerkulka kala-baxa wuxuu la mid yahay heerkulka farsamaynta (200-300°C) ee fiilooyinka caadiga ah (sida polyester iyo nayloon) si looga fogaado in si degdeg ah loo joojiyo.
3. Isku-dubaridka shaqooyinka badan
Shaqada xakamaynta qiiqa: Na₂O waxay dhexdhexaadisaa gaasaska aashitada waxayna yareysaa sunta qiiqa (qiimaha LOI waxaa lagu kordhin karaa 2–3%);
Ka-hortagga daadinta: Marka lagu daro waxyaabaha aan dabiiciga ahayn (sida dhoobada nano), qaab-dhismeedka lakabka kaarboonku wuu cufan yahay.
III. Caqabadaha Suurtagalka ah ee ku saabsan Isticmaalka Sodium Antimonate
1. Isu dheelitirka kharashka iyo isticmaalka
Qiimaha sare ee alaabta ceeriin: Habka isku-darka ee sodium antimonate waa mid adag qiimuhuna waa qiyaastii 1.2–1.5 jeer ka Sb₂O₃;
Waxtarka lidka ku ah antimony-ga oo hooseeya: Heerka la mid ah kan dab-damiska, xaddiga ku darista waa in la kordhiyaa 20-30% (sababtoo ah curiyaha sodium-ku wuxuu yareeyaa heerka lidka ku ah antimony-ga). Si kastaba ha ahaatee, UrbanMines Tech. Ltd., oo leh faa'iidooyinkeeda cilmi-baarista iyo horumarinta gaarka ah, waxay hagaajin kartaa kharashka wax soo saarka ee sodium antimonate si uu uga hooseeyo antimony trioxide oo si dhakhso ah u qabsada qayb weyn oo ka mid ah saamiga suuqa adduunka nus sano gudahood.
2. Arrimaha iswaafajinta farsamada
Xasaasiyadda pH: Alkaline Na₂O waxay saameyn kartaa xasilloonida dhalaalka ee qaar ka mid ah resins-ka (sida PET);
Xakamaynta midabka: Hadhaaga soodhiyam ee heerkul sare wuxuu sababi karaa huruud yar oo faybarka ah, taasoo u baahan in lagu daro midabyo.
3. Isku halaynta muddada dheer waxay u baahan tahay in la xaqiijiyo
Kala duwanaanshaha iska caabbinta cimilada: Socdaalka ion-ka Sodium ee deegaannada kulul iyo qoyan waxay saameyn kartaa adkeysiga dib-u-dhaca ololka;
Caqabadaha Dib-u-warshadaynta: Habka dib-u-warshadaynta kiimikada ee fiilooyinka ka hortagga ololka ee ay ku jirto sodium ayaa loo baahan yahay in dib loo habeeyo.
