Njira yowunikira yosinthira pamwamba pa ultrafine aluminiyamu hydroxide

1. Kuyesa kuchuluka kwa mafuta kudzachitika pogwiritsa ntchito ufa wa aluminiyamu hydroxide wopangidwa ndi ultrafine molingana ndi chitsanzo chouma cha 10 g, choyikidwa mu beaker, burette ndi mafuta a castor, mofatsa, ndi ndodo yagalasi yokhala ndi chitsanzo cha mafuta a castor, mawonekedwe ofanana a briquetting omwe amawerengedwa pa 100 g ya aluminiyamu hydroxide, kuchuluka kwa mafuta a castor, kuchuluka kwa mafuta a aluminiyamu hydroxide, kuchuluka kwa mafuta a aluminium hydroxide ufa wabwino kwambiri kudzera mu kusintha kwa pamwamba pa ufa wa aluminiyamu hydroxide, kuchuluka kwa mafuta kudzawoneka pamlingo winawake wa kusintha monga silane coupling agent modified ultrafine aluminiyamu hydroxide powder, kuchuluka kwa mafuta a hydroxide kudzachepa ndi 10%.

2. Mayeso a SEM Musanayambe komanso mutatha kusintha zida zoyesera za ufa wa aluminiyamu hydroxide zomwe zimagwiritsidwa ntchito ndi maikulosikopu yamagetsi komanso pogwiritsa ntchito maikulosikopu yamagetsi (sem) zimapezeka mkati mwa ufa wosinthidwa mu matrix ndi zabwino kuposa zinthu zosasinthidwa.

3. Mayesowa AGWIRITSA NTCHITO Fourier infrared spectrometer (FTIR) ya infrared spectrometry, kusanthula pamwamba pa mamolekyu azinthu monga kugwiritsa ntchito methyl vinyl silane wet surface modification ya aluminiyamu hydroxide powder, infrared spectrum ikhoza kudziwika kudzera mu

Kutsimikiza kwa kuchuluka kwa zinthu mu vinyl Vi ndi Si kudzasinthidwa ndipo zinthu zopangidwa ndi ufa wa aluminiyamu wa hydroxide wosasinthidwa wa ultrafine wosasinthidwa wa zizindikiro za chingwe monga index ya okosijeni5. Chizindikiro cha kuyambitsa sodium stearate titanate chinasinthidwa wet, ufa wa hydrophobic silane wouma wosinthidwa ultrafine aluminiyamu hydroxide, index ya kuyambitsa ingagwiritsidwe ntchito kuwunika momwe kusintha kumakhalira; Komabe, silane ya hydrophilic idasinthidwa ndi njira youma, ndipo ufa wa ultrafine aluminiyamu hydroxide wosinthidwa ndi njira yonyowa ya silane ungamire m'madzi, kotero kusintha sikungathe kuyesedwa ndi index ya kuyambitsa, ndipo njira yolondola yowunikira inali infrared spectroscopy.
