I-Colloidal antimony pentoxide iwumkhiqizo ovimbela ilangabi we-antimony owasungulwa amazwe athuthukile ngasekupheleni kwawo-1970. Uma iqhathaniswa ne-antimony trioxide flame retardant, inezici ezilandelayo zokusetshenziswa:
1. I-colloidal antimony pentoxide flame retardant inomusi omncane. Ngokuvamile, umthamo obulalayo we-LD50 we-antimony trioxide kumagundane (umgodi wesisu) ngu-3250 mg/kg, kanti i-LD50 ye-antimony pentoxide ingu-4000 mg/kg.
2. I-Colloidal antimony pentoxide ihambisana kahle nezinyibilikisi eziningi eziphilayo ezifana namanzi, i-methanol, i-ethylene glycol, i-acetic acid, i-dimethylacetamide kanye ne-amine formate. Uma kuqhathaniswa ne-antimony trioxide, kulula ukuxuba nezilawuli zomlilo ze-halogen ukuze kwakhiwe izinhlobo ezahlukene zezilawuli zomlilo ezihlanganisiwe ezisebenza kahle kakhulu.
3. Usayizi wezinhlayiya ze-colloidal antimony pentoxide ngokuvamile ungaphansi kuka-0.1mm, kuyilapho i-antimony trioxide kunzima ukuyilungisa ibe yinhlayiya. I-Colloidal antimony pentoxide ifaneleka kakhulu ukusetshenziswa kumafayibha namafilimu ngenxa yobukhulu bayo obuncane bezinhlayiya. Ekuguqulweni kwesisombululo sokuphotha i-fiber yamakhemikhali esigcina ilangabi, ukwengeza i-gelatinized antimony pentoxide kungagwema isimo sokuvimba imbobo yokuphotha nokunciphisa amandla okuphotha okubangelwa ukwengeza i-antimony trioxide. Lapho i-antimony pentoxide ingezwa ekuqedeni kwendwangu okugcina ilangabi, ukunamathela kwayo ebusweni bendwangu kanye nokuqina komsebenzi wokuphotha ilangabi kungcono kunokwe-antimony trioxide.
4. Uma umphumela wokuvimbela ilangabi ufana, inani le-colloidal antimony pentoxide esetshenziswa njengesibambi somlilo lincane, ngokuvamile liyi-30% kuphela ye-antimony trioxide. Ngakho-ke, ukusetshenziswa kwe-colloidal antimony pentoxide njengesibambi somlilo kunganciphisa ukusetshenziswa kwe-antimony futhi kuthuthukise kakhulu izakhiwo ezahlukahlukene zomzimba nezomshini wemikhiqizo yesibambi somlilo.
5. I-antimony trioxide isetshenziselwa ama-substrate e-resin okwenziwa agcina ilangabi, azofaka ubuthi ku-catalyst ye-Pd ngesikhathi sokufaka i-electroplating futhi abhubhise ichibi lokufaka i-unplated. I-Colloidal antimony pentoxide ayinalo leli phutha.
Ngenxa yokuthi i-colloidal antimony pentoxide flame retardant inezici ezingenhla, isetshenziswe kabanzi emikhiqizweni evimbela umlilo efana namakhaphethi, izembozo, ama-resins, irabha, izindwangu ze-fiber zamakhemikhali emazweni athuthukile. Onjiniyela abavela e-Technology R&D Center ofUrbanMines Tech. Limited bathole ukuthi kunezindlela eziningi zokulungiselela i-colloidal antimony pentoxide. Njengamanje, i-hydrogen peroxide isetshenziswa kakhulu ekulungiseleleni. Kunezinhlobo eziningi zezindlela ze-hydrogen peroxide. Manje ake sithathe isibonelo: engeza izingxenye ezingu-146 ze-antimony trioxide kanye nezingxenye ezingu-194 zamanzi ku-reflux reactor, uvuselele ukuze wenze i-slurry ehlakazekile ngokulinganayo, bese ufaka kancane kancane izingxenye ezingu-114 ze-30% hydrogen peroxide ngemva kokushisa ku-95℃, yenze i-oxidize futhi ivuselele imizuzu engu-45, bese kuthi isixazululo se-colloidal antimony pentoxide esingu-35% sobumsulwa singatholakala. Ngemva kokuba isixazululo se-colloidal sesipholile kancane, hlunga ukuze ususe izinto ezinganyibiliki, bese womisa ku-90℃, kungatholakala i-powder emhlophe enamanzi ye-antimony pentoxide. Uma ungeza izingxenye ezingu-37.5 ze-triethanolamine njengesiqinisi ngesikhathi sokugaya, isixazululo se-colloidal antimony pentoxide esilungisiwe siphuzi futhi siqinile, bese somile ukuze kutholakale i-powder ye-antimony pentoxide ephuzi.
Ukusebenzisa i-antimony trioxide njengezinto zokusetshenziswa ukulungisa i-colloidal antimony pentoxide ngendlela ye-hydrogen peroxide, le ndlela ilula, inqubo yezobuchwepheshe imfushane, ukutshalwa kwezimali kwemishini kuphansi, futhi izinsiza ze-antimony zisetshenziswa ngokugcwele. Ithani elilodwa le-antimony trioxide evamile lingakhiqiza amathani ayi-1.35 e-colloidal antimony pentoxide impuphu eyomile kanye namathani angu-3.75 esisombululo se-colloidal antimony pentoxide esingu-35%, okungakhuthaza ukukhiqizwa kwemikhiqizo evimbela ilangabi futhi kwandise amathuba okusetshenziswa kabanzi kwemikhiqizo evimbela ilangabi.
