Q: Ingabe i-hydrophobic gas phase silica ingasetshenziswa ezindaweni zokuxhumana zokudla noma ezixhunywayo (isb. izixhunywa zokupakisha ukudla)? A: Yebo. Imikhiqizo yethu ihambisana ne-US FDA 21 CFR §177.2600 kanye ne-EU No 10/2011 standard yokuxhumana kokudla. Q: Ungakhetha kanjani indawo ethile efanele ye-hydrophobic gas phase silica ngokwezinga lesistimu? A: Ithimba lobuchwepheshe lizohlinzeka ngohlelo lokukhetha ngokuya ngezici zesistimu yakho kanye nokusebenza okuhlosiwe, futhi liqinisekise amapharamitha aphumelelayo ngokuhlola okuphakeme (uhlolo lwe-rheological, ukuhlola ukusebenza kokufaka). Q: Ingabe kudingeka imishini ethile yokuhlakulela noma izithasiselo uma umkhiqizo uhlinzekwa ohlelweni lwe-aqueous? A: Akudingi imishini ethile. Siphumelele ukuthuthukisa imodeli ekhethekile yohlelo lwe-aqueous, engahlala ihlukaniswe kahle emishinini yokuhlakulela ejwayelekile (isb. i-high-speed disperser kanye ne-sand mill) (2000r/min ukuxuba imizuzu engama-20), ngaphandle kokwengeza izithasiselo zokuhlakulela. Q: Uma kudingeka ulungise uhlobo lokuguqulwa ngemuva kokuhlola okuncane, ingabe isikhathi sokukhiqiza sizokwandiswa kakhulu? A: Cha. Sine-line yokukhiqiza yokuguqulwa kwesurface eyakhelwe ngokuqondile evumela ukushintsha ngokushesha kwezinhlobo ze-modifier (isb. kusuka ku-dimethyl dichlorosilane kuya ku-hexamethyl disilazane), nezikhathi zokwenza ngokwezifiso zithatha kuphela izinsuku eziyi-12-18 – eziphindwe kabili ezingama-80% ngaphansi kwalesi sikhathi esijwayelekile embonini. Lokhu kuvumela amaklayenti ukuthi aqinisekise izilungiselelo ngokushesha futhi anciphise izindleko ze-R&D.
