1. Ukuhlolwa kwezinga lokumuncwa kwamafutha kuzothatha i-aluminium hydroxide powder e-ultrafine ngokusho kokuthatha isampula eyomile engu-10 g, efakwe ku-beaker, i-burette kanye ne-castor oil, ngobumnene, ngenduku yengilazi enesampula yamafutha e-castor, isimo esifanayo sokufakwa kwe-briquetting esibalwa nge-100 g yenani lokumuncwa kwe-aluminium hydroxide lamafutha e-castor, izinga lokumuncwa kwamafutha le-aluminium hydroxide powder enhle kakhulu ngokuguqulwa kobuso be-aluminium hydroxide powder, izinga lokumuncwa kwamafutha lizovela ngezinga elithile lokushintsha njenge-silane coupling agent modified ultrafine aluminium hydroxide powder, izinga lokumuncwa kwamafutha lizokwehla ngo-10%
2. Ukuhlolwa kwe-SEM Ngaphambi nangemva kokuguqulwa kwe-ultrafine aluminum hydroxide powder morphology imishini yokuhlola i-morphology esetshenziswa yi-electronic microscope scan kanye ne-electron microscopy (sem) ingatholakala ngaphakathi kokusabalala kwe-modified powder ku-matrix ingcono kunemikhiqizo engaguquliwe
3. Ukuhlolwa KUSEBENZISA i-Fourier infrared spectrometer (FTIR) ye-infrared spectrometry, ukuhlaziywa ebusweni bama-molecule womkhiqizo njengokusebenzisa ukuguqulwa kobuso obumanzi be-methyl vinyl silane ye-aluminium hydroxide powder, i-infrared spectrum ingatholakala ngokusebenzisa
Ukunqunywa kokuqukethwe kwe-vinyl Vi ne-Si okungu-4 kokusebenza kwemikhiqizo kuzoshintshwa futhi imikhiqizo eyenziwe nge-ultrafine aluminium hydroxide powder engashintshwanga yezinkomba zekhebula njenge-oxygen index5. I-Activation index sodium stearate titanate yashintshwa ngamanzi, i-hydrophobic silane dry modified ultrafine aluminium hydroxide powder, i-activation index ingasetshenziswa ukuhlola umphumela wokuguqulwa; Kodwa-ke, i-hydrophilic silane yashintshwa ngendlela eyomile, kanti i-ultrafine aluminium hydroxide powder eshintshwa ngendlela emanzi ye-silane yayizocwila emanzini, ngakho umphumela wokuguqulwa wawungeke uhlolwe nge-activation index, futhi indlela yokuhlola enembile yayiyi-infrared spectroscopy.
