I-aluminium hydroxide powder ene-flame retardant, ukuqedwa komusi, ukugcwalisa kanye neminye imisebenzi eminingi, kungaveza umphumela we-synergistic flame retardant nge-phosphorus nezinye izinto, izinhlobonhlobo zemikhiqizo yamakhemikhali, isibe yi-electronic, amakhemikhali, ikhebula, amapulasitiki, irabha kanye nezinye izimboni endaweni ebalulekile yokuvikela ilangabi lomlilo. I-Aluminium hydroxide njenge-filler inorganic flame retardant, ukuze kuzuzwe umphumela ongcono we-flame retardant, inani lokugcwalisa lidinga u-40%, kuze kufike ku-60%, kodwa inani eliphezulu lokugcwalisa alithinti nje kuphela izakhiwo zemishini yemikhiqizo, futhi izakhiwo ze-extrusion nokucubungula ziba zimbi kakhulu. Ngakho-ke, ukuguqulwa kwendawo kuyadingeka.
Khetha izilungisi ezihlukene zendawo kanye namanani ahlukene ezilungisi zokushintsha indawo emanzii-aluminium hydroxide. Ngokusebenzisa inani lokumuncwa kwamafutha e-aluminium hydroxide powder ngaphambi nangemva kokuguqulwa, izakhiwo ezingaphezulu ze-aluminium hydroxide powder eziguquliwe zishintshile ngokusobala, i-hydrophilicity kanye nenani lokumunca uwoyela lehle kakhulu, futhi ukuhlakazeka kwesigaba sezinto eziphilayo kwanda ngokusobala. Ukuguqulwa kwendawo nakho kuba nomthelela ezintweni ze-aluminium hydroxide composite system. Ukuvinjelwa kwelangabi kanye nendlela yokuthuthukisa ye-aluminiyamu hydroxide eyenziwe yasebenza kahle kakhulu kwahlaziywa ngokuhlaziywa kwe-thermogravimetric nokuskena i-electron microscopy. Ukuguqulwa kwendawo kungathuthukisa kakhulu izakhiwo ezibanzi zohlelo lwe-PVC olugcwele i-aluminium hydroxide. Kukhethwe izinhlanganisela eziningana zezinto eziphilayo ukuze kulungiswe ingaphezulu le-alumina hydroxide powder. Ngokuhlaziywa kwenani lokumuncwa kukawoyela, i-activation degree kanye nosayizi wezinhlayiyana zempushana eguquliwe, ukuguqulwa kwezinto eziphilayo kwenza usayizi wezinhlayiyana ze-alumina hydroxide powder waba mncane. Indlela yokuhlanganisa amakhemikhali esikhundleni sendlela yendabuko yokuhlanganisa ngokomzimba ingathuthukisa ukuzinza kokuhlakazeka nokuhambisana kwe-nano-hydroxide flame retardant kuma-polymer ephilayo.
Kungakhathaliseki indlela yokuguqulwa kwe-aluminium hydroxide, ungasebenzisa umshini wokuguqula i-powder surface ukugaya izinyosi, inqubo yokuguqulwa koju lwezinyosi kuwuhlobo lwesistimu yokushanela umoya, impahla ngokusebenzisa ukugeleza komoya ohlelweni ukuze ushintshe izici, umthamo wokuphatha omncane wamathani angu-0.05 / ihora, umkhawulo wamathani angu-15 ngehora.
