Isingeniso ku-Zinc Borate

I-Zinc borate iyi-inorganic flame retardant esebenza kahle kakhulu, enobungani nemvelo ehlanganisa ukuvinjelwa komlilo, ukucindezela intuthu kanye nezakhiwo zokulwa nokuconsa. Ingxenye yayo eyinhloko yi-2ZnO·3B₂O₃·3.5H₂O, futhi ibonakala njengempuphu emhlophe noma ephuzi engavamile noma e-rhombic. Njengoba izinzile kakhulu ngamakhemikhali kanye nokuzivumelanisa nezimo kokucubungula, iyinto ekhethwayo yokuthuthukisa ukuphepha embonini yerabha nepulasitiki, yokumboza, yezintambo kanye neyekhebula.

Lo mkhiqizo uziqhenya ngokuqina kokushisa okuvelele, kancane kancane ulahlekelwa amanzi ekristalu ngaphezu kuka-320℃ kuphela. Awuboli noma uguquke kubuchwepheshe bokucubungula obusezingeni eliphezulu njengokukhipha, ukubumba ngemijovo kanye nokufutha, futhi ungagcina ukusebenza kahle okuzinzile okuvimbela ilangabi. Awuncibiliki ezinyibilikisini ezivamile zezinto eziphilayo ezifana namanzi, i-ethanol, i-benzene kanye ne-acetone, kodwa uncibilika kalula ku-hydrochloric acid, i-sulfuric acid kanye ne-dimethyl sulfoxide (DMSO). Njengoba uhlakazeka kahle kakhulu, uhambisana kahle nezingxenye ezahlukene ezifaka i-PVC, i-PE, i-PP, irabha kanye ne-resin, futhi awuthinti ukubukeka, amandla okusebenza noma ukusebenza okuguga kwemikhiqizo eqediwe ngemva kokufakwa.

Ngokuphathelene nendlela yokuvimbela ilangabi, i-zinc borate yehlisa izinga lokushisa ngokubola kwe-endothermic emazingeni okushisa aphezulu, ikhipha amanzi ekristalu ukuze inciphise amagesi avuthayo, futhi yakhe ungqimba oluqinile oluvikelayo olufana nengilazi ukuze luhlukanise umoya-mpilo, ngaleyo ndlela kufezwe imiphumela emithathu yokuvimbela ilangabi, ukucindezela intuthu kanye nokulwa nokuconsa. Ingasetshenziswa ngokubambisana ne-aluminium hydroxide, i-magnesium hydroxide kanye ne-organophosphorus flame retardants ukuthuthukisa kakhulu izinga lezinto ezivimbela ilangabi. Ingaphinde ithathe indawo yezinto ezivimbela ilangabi zendabuko njenge-antimony trioxide, inciphise ngempumelelo izindleko zefomula.

Lo mkhiqizo awunabo ubuthi, awunaphunga futhi awunangcolisi, uhambisana nokuvikelwa kwemvelo kwamazwe ngamazwe kanye nezindinganiso zokuvimbela umlilo. Usetshenziswa kabanzi emikhakheni efana nezintambo nezintambo, izembozo ezingashi, amapayipi epulasitiki, imikhiqizo yerabha kanye nama-resin e-polyester angagcwele. Kungakhathaliseki ukuthi kusetshenziselwa ukuguqulwa kwezinto ezisezingeni eliphezulu ekukhiqizweni kwezimboni noma izidingo zokuhambisana nokuphepha kwemikhiqizo yomphakathi, i-zinc borate inganikeza izixazululo ezithembekile zokuvimbela umlilo, isize amabhizinisi ukuthi afinyelele ukuthuthukiswa komkhiqizo kanye nokukhiqizwa okuhambisana nomthetho.
