I-Colloidal antimony pentoxide yimveliso ethintela ilangatye le-antimony eyenziwe ngamazwe aphuhlileyo ngasekupheleni kweminyaka yoo-1970. Xa ithelekiswa ne-antimony trioxide flame retardant, ineempawu ezilandelayo zokusetyenziswa:
1. I-colloidal antimony pentoxide flame retardant inomsi omncinci. Ngokubanzi, idosi ebulalayo ye-LD50 ye-antimony trioxide kwiimpuku (umgodi wesisu) yi-3250 mg/kg, ngelixa i-LD50 ye-antimony pentoxide iyi-4000 mg/kg.
2. I-Colloidal antimony pentoxide ihambelana kakuhle nezinyibilikisi ezininzi ze-organic ezifana namanzi, i-methanol, i-ethylene glycol, i-acetic acid, i-dimethylacetamide kunye ne-amine formate. Xa kuthelekiswa ne-antimony trioxide, kulula ukuyixuba nezithinteli zomlilo ze-halogen ukuze kwenziwe iintlobo ezahlukeneyo zezithinteli zomlilo ezidityanisiweyo ezisebenzayo.
3. Ubungakanani be-particle ye-colloidal antimony pentoxide ngokubanzi bungaphantsi kwe-0.1mm, ngelixa i-antimony trioxide kunzima ukuyicoca ibe bubungakanani be-particle. I-Colloidal antimony pentoxide ifanelekile ngakumbi ukusetyenziswa kwi-fibers nakwiifilimu ngenxa yobukhulu bayo obuncinci be-particle. Ekuguqulweni kwesisombululo se-flame retardant chemical fiber spinning, ukongeza i-gelatinized antimony pentoxide kunokuthintela isiganeko sokuvala umngxuma ojikelezayo nokunciphisa amandla okujikeleza abangelwa kukongeza i-antimony trioxide. Xa i-antimony pentoxide yongezwa ekugqityweni kwe-flame retardant yelaphu, ukunamathela kwayo kumphezulu welaphu kunye nokuqina komsebenzi we-flame retardant kungcono kune-antimony trioxide.
4. Xa isiphumo sokurhoxisa ilangatye siyafana, ubungakanani be-colloidal antimony pentoxide esetyenziswa njengesithinteli ilangatye buncinci, ngokubanzi yi-30% kuphela ye-antimony trioxide. Ke ngoko, ukusetyenziswa kwe-colloidal antimony pentoxide njengesithinteli ilangatye kunokunciphisa ukusetyenziswa kwe-antimony kwaye kuphucule ngakumbi iipropati ezahlukeneyo zomzimba kunye noomatshini beemveliso zesithinteli ilangatye.
5. I-Antimony trioxide isetyenziselwa ii-substrates ze-resin zokwenziwa ezithintela ilangatye, eziya kuthi zityhefe i-Pd catalyst ngexesha lokufakelwa kwe-electroplating kwaye zitshabalalise ichibi le-plating elingafakwanga. I-Colloidal antimony pentoxide ayinalo olu buthathaka.
Ngenxa yokuba i-colloidal antimony pentoxide flame retardant ineempawu ezingentla, isetyenziswa kakhulu kwiimveliso ze-flame retardant ezifana neekhaphethi, ii-coating, ii-resins, irabha, amalaphu e-chemical fiber kumazwe aphuhlileyo. Iinjineli ezivela kwi-Technology R&D Center ofUrbanMines Tech. Limited zifumanise ukuba kukho iindlela ezininzi zokulungiselela i-colloidal antimony pentoxide. Okwangoku, i-hydrogen peroxide isetyenziswa kakhulu ekulungiseleleni. Kukwakho neentlobo ezininzi zeendlela ze-hydrogen peroxide. Ngoku masithathe umzekelo: yongeza iinxalenye ezili-146 ze-antimony trioxide kunye neenxalenye ezili-194 zamanzi kwi-reflux reactor, uvuselele ukwenza i-slurry esasazeke ngokulinganayo, kwaye wongeze kancinci iinxalenye ezili-114 ze-30% hydrogen peroxide emva kokufudumeza ukuya kwi-95℃, uyenze i-oxidize kwaye ibuyele kwi-reflux imizuzu engama-45, kwaye emva koko isisombululo se-colloidal antimony pentoxide esingama-35% singafunyanwa. Emva kokuba isisombululo se-colloidal sipholisiwe kancinci, hluza ukuze ususe izinto ezinganyibilikiyo, uze womise kwi-90℃, umgubo omhlophe omanzi we-antimony pentoxide ungafunyanwa. Ukongeza iinxalenye ezingama-37.5 ze-triethanolamine njengesiqinisi ngexesha lokuxuba, isisombululo se-colloidal antimony pentoxide esilungisiweyo sityheli kwaye siqinile, size some ukuze kufunyanwe umgubo we-antimony pentoxide otyheli.
Ukusebenzisa i-antimony trioxide njengezinto zokwenza imveliso ukulungiselela i-colloidal antimony pentoxide ngendlela ye-hydrogen peroxide, le ndlela ilula, inkqubo yetekhnoloji imfutshane, utyalo-mali lwezixhobo luphantsi, kwaye izixhobo ze-antimony zisetyenziswa ngokupheleleyo. Itoni enye ye-antimony trioxide eqhelekileyo inokuvelisa iitoni eziyi-1.35 ze-colloidal antimony pentoxide powder eyomileyo kunye neetoni eziyi-3.75 zesisombululo se-colloidal antimony pentoxide esingama-35%, esinokukhuthaza ukuveliswa kweemveliso ezithintela ilangatye kwaye sandise amathuba okusetyenziswa ngokubanzi kweemveliso ezithintela ilangatye.
