Q: Ingabe i-hydrophobic gas phase silica ingasetshenziswa ezindaweni zokuxhumana zokudla noma ezixhunywe (isb. izixhunywe zokupakisha ukudla)? A: Yebo. Imikhiqizo yethu ihambisana ne-US FDA 21 CFR §177.2600 kanye ne-EU No 10/2011 izinga lokuxhumana kokudla. Q: Ungakhetha kanjani indawo ethile efanele ye-hydrophobic gas phase silica ngokwehlobo lesistimu? A: Ithimba lobuchwepheshe lizohlinzeka ngohlelo lokukhetha ngokwezakhiwo zesistimu yakho kanye nokusebenza okuhlosiwe, futhi liqinisekise amapharamitha aphumelela kakhulu ngokuhlola okuphakanyisiwe (uhlolo lwe-rheological, ukuhlolwa kokusebenza kokufaka). Q: Ingabe kudingeka imishini ethile yokuhlanza noma izithasiselo uma umkhiqizo uhlinzekwa ohlelweni lwe-aqueous? A: Akudingi imishini ethile. Siphumelele ukuthuthukisa imodeli ekhethekile ye-aqueous system, engahlala ihlukaniswe kahle emishinini yokuhlanza ejwayelekile (njengokuhlanza okusheshayo kanye ne-sand mill) (2000r/min ukuhamba kwemizuzu engama-20), ngaphandle kokwengeza izithasiselo zokuhlanza. Q: Uma kudingeka ulungise uhlobo lokuguqulwa ngemuva kokuhlola okuncane, ingabe isikhathi sokukhiqiza sizokwandiswa kakhulu? A: Cha. Sine-line yokukhiqiza yokuguqulwa kwe-surface eyakhelwe, evumela ukushintsha ngokushesha kwezinhlobo zokuguqula (isb. ukusuka ku-dimethyl dichlorosilane kuya ku-hexamethyl disilazane), nezikhathi zokwenza ngokwezifiso zithatha kuphela izinsuku eziyi-12-18 – okuphansi ngo-79% uma kuqhathaniswa nezinga lesimboni. Lokhu kuvumela amaklayenti ukuba aqinisekise izilungiselelo ngokushesha futhi anciphise izindleko ze-R&D.
