I-Colloidal antimony pentoxide yimveliso ye-antimony flame retardant eyaphuhliswa ngamazwe ahambele phambili kwezoshishino ekupheleni kweminyaka yee-1970.Xa kuthelekiswa ne-antimony trioxide flame retardant, inezi mpawu zilandelayo:
1. I-colloidal antimony pentoxide flame retardant inomsi omncinci womsi.Ngokuqhelekileyo, idosi ebulalayo i-LD50 ye-antimony trioxide kwiigundane (i-cavity yesisu) yi-3250 mg / kg, ngelixa i-LD50 ye-antimony pentoxide yi-4000 mg / kg.
2. I-colloidal antimony pentoxide inokuhambelana kakuhle kunye ne-solvents ezininzi zezinto eziphilayo ezifana namanzi, i-methanol, i-ethylene glycol, i-acetic acid, i-dimethylacetamide kunye ne-amine formate.Xa kuthelekiswa ne-antimony trioxide, kulula ukuxuba kunye ne-halogen flame retardants ukwenza iintlobo ezahlukeneyo ze-high-effective composite flame retardants.
3. Ubungakanani be-particle ye-colloidal antimony pentoxide ngokuqhelekileyo ingaphantsi kwe-0.1mm, ngelixa i-antimony trioxide inzima ukuyicokisa kule nxalenye yesayizi.I-Colloidal antimony pentoxide ifaneleke ngakumbi ukusetyenziswa kwiifibers kunye neefilimu ngenxa yobukhulu bayo obuncinci.Ekuguqulweni kwesisombululo se-flame retardant i-fiber fiber spinning, ukongeza i-gelatinized i-antimony pentoxide inokuphepha into yokuthintela umngxuma ojikelezayo kunye nokunciphisa amandla okujikeleza okubangelwa ukongeza i-antimony trioxide.Xa i-antimony pentoxide yongezwa kwi-flame retardant ekugqityweni kwelaphu, ukunamathela kwayo phezu kwelaphu kunye nokuqina komsebenzi we-flame retardant kungcono kunezo ze-antimony trioxide.
4. Xa i-flame retardant effect ifana, inani le-colloidal antimony pentoxide esetyenziswa njenge-flame retardant lincinci, ngokubanzi kuphela i-30% ye-antimony trioxide.Ke ngoko, ukusetyenziswa kwe-colloidal antimony pentoxide njenge-flame retardant kunokunciphisa ukusetyenziswa kwe-antimony kwaye kuphuculwe ngakumbi iipropathi ezahlukeneyo zomzimba kunye nomatshini weemveliso ezibuyiswa ngamadangatye.
5. I-Antimony trioxide isetyenziselwa i-flame-retardant synthetic resin substrates, eya kuthi ityhefu i-Pd catalyst ngexesha le-electroplating kwaye itshabalalise i-plating pool engaxutywanga.I-antimony pentoxide ye-Colloidal ayinayo le ntsilelo.
Ngenxa yokuba i-colloidal antimony pentoxide flame retardant ineempawu ezingentla, isetyenziswe ngokubanzi kwiimveliso ezibuyiswa ngumlilo ezifana neekhaphethi, iingubo, iirasi, irabha, amalaphu ekhemikhali ifayibha kumazwe aphuhlileyo.Iinjineli ezisuka kwiZiko leTekhnoloji yeR&D yeUrbanMines Tech.Limited ifumanise ukuba zininzi iindlela zokulungiselela icolloidal antimony pentoxide.Okwangoku, i-hydrogen peroxide isetyenziswa kakhulu ekulungiseleleni.Kukho neentlobo ezininzi zeendlela zehydrogen peroxide.Ngoku makhe sithathe umzekelo: yongeza izahlulo ezili-146 ze-antimony trioxide kunye ne-194 yezahlulo zamanzi kwi-reflux reactor, uvuselele ukwenza i-slurry ehlakazeke ngokufanayo, kwaye ngokucotha ukongeza i-114 izahlulo ze-30% ye-hydrogen peroxide emva kokufudumeza kwi-95 ℃, yenze i-oxidize kwaye reflux imizuzu engama-45, kwaye ke 35% ubunyulu colloidal antimony pentoxide isisombululo inokufumaneka.Emva kokuba isisombululo se-colloidal sipholile kancinane, isihluzo sokususa into engaxutywanga, kwaye yomile kwi-90 ℃, i-powder emhlophe ye-hydrated ye-antimony pentoxide ingafumaneka.Ukongeza iinxalenye ze-37.5 ze-triethanolamine njenge-stabilizer ngexesha lokucoca, isisombululo se-colloidal antimony pentoxide silungiswa. tyheli kunye ne-viscous, kwaye emva koko yome ukufumana i-yellow antimony pentoxide powder.
Ukusebenzisa i-antimony trioxide njengento ekrwada ukulungiselela i-colloidal antimony pentoxide ngendlela ye-hydrogen peroxide, indlela ilula, inkqubo yezobuchwepheshe imfutshane, utyalo-mali lwezixhobo luphantsi, kwaye izixhobo ze-antimony zisetyenziswa ngokupheleleyo.Itoni enye ye-antimony trioxide eqhelekileyo inokuvelisa i-1.35 yeetoni ze-colloidal antimony pentoxide eyomileyo yomgubo kunye ne-3.75 yeetoni ze-35% yesisombululo se-antimony pentoxide ye-colloidal, enokukhuthaza ukuveliswa kweemveliso ze-flame retardant kunye nokwandisa amathuba okusetyenziswa kwe-flame retardant.
