1. Qhov kev sim nqus roj yuav siv 10 g ntawm cov hmoov txhuas hydroxide uas zoo heev raws li cov qauv qhuav, muab tso rau hauv lub beaker, burette thiab castor roj, maj mam, nrog ib lub iav pas nrig nrog cov qauv roj castor sib xws infiltration briquetting duab xam rau txhua 100 g ntawm cov roj castor txhuas hydroxide adsorption, qhov nqus roj rau cov hmoov txhuas hydroxide zoo heev los ntawm kev hloov kho ntawm qhov chaw ntawm cov hmoov txhuas hydroxide, qhov nqus roj yuav tshwm sim qee qib ntawm kev hloov pauv xws li silane coupling agent hloov kho ultrafine txhuas hydroxide hmoov, qhov nqus roj yuav poob qis 10%.
2. Kev xeem SEM Ua ntej thiab tom qab kev hloov kho ntawm cov khoom siv kuaj morphology hmoov txhuas hydroxide ultrafine siv los ntawm kev ntsuas lub tshuab hluav taws xob thiab los ntawm electron microscopy (sem) tuaj yeem pom sab hauv kev sib kis ntawm cov hmoov hloov kho hauv matrix zoo dua li cov khoom tsis hloov kho
3. Qhov kev sim siv Fourier infrared spectrometer (FTIR) ntawm infrared spectrometry, kev tshuaj xyuas ntawm qhov chaw ntawm cov khoom lag luam xws li siv methyl vinyl silane ntub dej hloov kho ntawm txhuas hydroxide hmoov, infrared spectrum tuaj yeem txiav txim siab los ntawm
4 vinyl Vi thiab Si cov ntsiab lus kev txiav txim siab ntawm cov khoom ua tau zoo yuav raug hloov kho thiab unmodified ultrafine aluminium hydroxide hmoov ua cov khoom rau cable qhia xws li oxygen index5. Activation index sodium stearate titanate yog ntub hloov kho, hydrophobic silane qhuav hloov kho ultrafine aluminium hydroxide hmoov, qhov activation index tuaj yeem siv los ntsuas qhov hloov kho; Txawm li cas los xij, hydrophilic silane tau hloov kho los ntawm txoj kev qhuav, thiab ultrafine aluminium hydroxide hmoov hloov kho los ntawm silane ntub yuav tog hauv dej, yog li qhov hloov kho tsis tuaj yeem ntsuas los ntawm activation index, thiab txoj kev ntsuas qhov tseeb yog infrared spectroscopy.
