I-Colloidal antimony pentoxide iwumkhiqizo we-antimony flame retardant owakhiwa amazwe anezimboni ngasekupheleni kwawo-1970. Uma iqhathaniswa ne-antimony trioxide flame retardant, inezici zohlelo lokusebenza ezilandelayo:
1. I-colloidal antimony pentoxide flame retardant inentuthu encane. Ngokuvamile, umthamo obulalayo we-LD50 we-antimony trioxide kumagundane (umgodi wesisu) ungu-3250 mg/kg, kuyilapho i-LD50 ye-antimony pentoxide ingu-4000 mg/kg.
2. I-Colloidal antimony pentoxide inokuhambisana okuhle nezinyibilikizi eziningi eziphilayo ezifana namanzi, i-methanol, i-ethylene glycol, i-acetic acid, i-dimethylacetamide ne-amine formate. Uma kuqhathaniswa ne-antimony trioxide, kulula ukuxutshwa nama-halogen flame retardants ukuze kwakheke inhlanganisela esebenza kahle kakhulu eyinhlanganisela ye-flame retardants.
3. Usayizi wezinhlayiyana ze-colloidal antimony pentoxide ngokuvamile ungaphansi kuka-0.1mm, kuyilapho i-antimony trioxide kunzima ukuyicwenga kulo sayizi wezinhlayiyana. I-Colloidal antimony pentoxide ifaneleka kakhulu ukusetshenziswa kumafayibha namafilimu ngenxa yobukhulu bayo bezinhlayiyana. Ekulungisweni kwesisombululo se-fiber spinning samakhemikhali e-flame retardant, ukwengeza i-gelatinized antimony pentoxide kungagwema ukwenzeka kokuvimba imbobo yokuphotha kanye nokunciphisa amandla okuphotha okubangelwa ukwengeza i-antimony trioxide. Lapho i-antimony pentoxide yengezwa ekuqedeni kwe-flame retardant kwendwangu, ukunamathela kwayo ebusweni bendwangu kanye nokuqina komsebenzi wokubuyisela ilangabi kungcono kune-antimony trioxide.
4. Uma umphumela we-flame retardant ufana, inani le-colloidal antimony pentoxide elisetshenziswa njenge-flame retardant lincane, ngokuvamile kuphela ama-30% e-antimony trioxide. Ngakho-ke, ukusetshenziswa kwe-colloidal antimony pentoxide njenge-flame retardant kunganciphisa ukusetshenziswa kwe-antimony futhi kuthuthukise izici ezihlukahlukene zomzimba kanye nemishini yemikhiqizo ye-flame retardant.
5. I-Antimony trioxide isetshenziselwa ama-synthetic resin substrates e-retardant-retardant, okuzokwenza ushevu ku-Pd catalyst ngesikhathi se-electroplating futhi ibhubhise ichibi le-plating elingahlanganisiwe. I-antimony pentoxide ye-Colloidal ayinalo leli phutha.
Ngenxa yokuthi i-colloidal antimony pentoxide flame retardant inezici ezingenhla, isetshenziswe kakhulu emikhiqizweni evimbela ilangabi njengokhaphethi, okokunamathela, ama-resin, irabha, izindwangu zamakhemikhali e-fiber emazweni athuthukile. Onjiniyela abavela ku-Technology R&D Center ye-UrbanMines Tech. I- Limited ithole ukuthi ziningi izindlela 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, ugovuze ukuze wenze udaka oluhlakazeke ngokufanayo, bese wengeza kancane kancane izingxenye ezingu-114 ze-hydrogen peroxide engu-30% ngemva kokushisisa ku-95℃, yenze i-oxidize futhi i-reflux imizuzu engu-45, bese kutholakala isisombululo se-colloidal antimony pentoxide esingu-35%. Ngemuva kokuthi isixazululo se-colloidal sipholile kancane, isihlungi ukuze sisuse izinto ezingancibiliki, bese somile ku-90 ℃, i-powder emhlophe ye-hydrated ye-antimony pentoxide ingatholakala.Ukwengeza izingxenye ezingu-37.5 ze-triethanolamine njenge-stabilizer ngesikhathi se-pulping, isisombululo esilungisiwe se-colloidal antimony pentoxide ophuzi kanye ne-viscous, bese omile ukuze uthole impushana ye-antimony pentoxide ephuzi.
Ukusebenzisa i-antimony trioxide njengempahla eluhlaza ukulungisa i-colloidal antimony pentoxide ngendlela ye-hydrogen peroxide, indlela ilula, inqubo yezobuchwepheshe ifushane, ukutshalwa kwezimali kwemishini kuphansi, futhi izinsiza ze-antimoni zisetshenziswa ngokugcwele. Ithani elilodwa le-antimony trioxide evamile lingakhiqiza amathani angu-1.35 wempushana eyomisiwe ye-colloidal antimony pentoxide kanye namathani angu-3.75 esixazululo esingu-35% se-colloidal antimony pentoxide, esingakhuthaza ukukhiqizwa kwemikhiqizo evimbela ilangabi futhi andise amathemba okusetshenziswa okubanzi kwemikhiqizo ekhiqizwe amalangabi.
