1. Uvavanyo lwezinga lokufunxwa kweoyile luya kuba yi-ultrafine aluminium hydroxide powder ngokwemiqathango yokuthathwa kwe-10 g yesampulu eyomileyo, ebekwe kwi-beaker, i-burette kunye ne-castor oil, ngobunono, ngentonga yeglasi enesampulu yeoyile ye-castor isampuli yokungena ngokulinganayo kwi-briquetting shape ebalwe kwi-100 g ye-aluminium hydroxide adsorption ubungakanani be-castor oil, izinga lokufunxwa kweoyile kwi-super-fine aluminium hydroxide powder ngokuguqulwa komphezulu we-aluminium hydroxide powder, izinga lokufunxwa kweoyile liya kubonakala kwinqanaba elithile lotshintsho olufana ne-silane coupling agent modified ultrafine aluminium hydroxide powder, izinga lokufunxwa kweoyile liya kuncipha nge-10%
2. Uvavanyo lwe-SEM Ngaphambi nasemva kokuguqulwa kwezixhobo zovavanyo lwe-aluminium hydroxide powder morphology ezisetyenziswa yi-electronic microscope scan kunye ne-electron microscopy (sem) zinokufunyanwa ngaphakathi kokusasazwa kwe-modified powder kwi-matrix ingcono kuneemveliso ezingatshintshwanga.
3. Uvavanyo lusebenzisa i-Fourier infrared spectrometer (FTIR) ye-infrared spectrometry, uhlalutyo kumphezulu weemolekyuli zemveliso ezifana nokusebenzisa i-methyl vinyl silane wet surface modification ye-aluminium hydroxide powder, i-infrared spectrum inokufunyanwa ngokusebenzisa
Ukugqitywa komxholo we-vinyl Vi kunye ne-Si yemveliso kuya kuguqulwa kwaye iimveliso ezenziwe nge-aluminium hydroxide powder engaguqukiyo zezalathisi zekhebula ezifana ne-oxygen index5. I-Activation index sodium stearate titanate yaguqulwa ngamanzi, i-hydrophobic silane dry modified ultrafine aluminum hydroxide powder, i-activation index ingasetyenziselwa ukuvavanya isiphumo sokuguqulwa; Nangona kunjalo, i-hydrophilic silane yaguqulwa ngendlela eyomileyo, kwaye i-ultrafine aluminum hydroxide powder eguqulwe ngendlela emanzi ye-silane yayiza kutshona emanzini, ngoko ke isiphumo sokuguqulwa asinakuvavanywa nge-activation index, kwaye indlela echanekileyo yokuvavanya yayiyi-infrared spectroscopy.
