13. Features Item : Successful Use of Fumed Silica in Liquid Systems

- Successful Use of Fumed Silica in Liquid Systems .
- Hydrophilic and hydrophobic AEROSIL fumed silica grades are used in many liquid systems for viscosity control, anti-sag and anti-settling behavior, and for general rheological enhancement. To optimize efficiency and consistency of the behavior for all fumed silica grades, the following conditions are important for success. ...
- To maximize fumed silica efficiency and to ensure performance consistency, proper dispersion is required. Low shear dispersion with a propeller or stirring blade is insufficient shear for all AEROSIL grades and in general for all fumed silica. ... At these rates, minimal energy is used to wet the fumed silica. ... Other results of low shear rate are loss of efficiency, whereby more AEROSIL fumed silica needs to be added, poor grind behavior, settling, and poor storage stability.
- Higher surface area fumed silica grades usually require more energy intensive equipment for optimizing dispersion. ...
- Performance of all fumed silica grades normally improves with increasing shear forces.
- This is an environment where overdispersion of fumed silica may occur.
- Overdispersion results when fumed silica aggregates are broken down past an optimum aggregate size. ...
- When insufficient energy is put into systems, all changes in processing can drastically affect the efficiency of fumed silica and the consistency of the final product.
- Specific time should be allotted for wet-in of fumed silica packed in paper bags. Wet-in time is considered the time required for the fumed silica to be wetted by the vehicle. ... Once all the fumed silica is wetted (brought under the surface of the liquid), the mixing speed is increased and dispersion begins. Fumed silica should be wetted in as quickly as possible. ...

- mixing means for mixing said hydrogen peroxide solution with said fumed silica in said mixing chamber to produce a paste of said hydrogen peroxide solution and said fumed silica;.
- a cover releasably sealed to said tray, said cover being removable to expose said first compartment before said second compartment to allow the dental professional to retrieve said sealed container of hydrogen peroxide solution prior to exposing said body of fumed silica.
- a body of fumed silica in said second compartment;.
- mixing means for mixing said hydrogen peroxide into said fumed silica in said second compartment to form a paste comprising said fumed silica and said quantity of hydrogen peroxide, said paste being prepared immediately prior to being applied to the teeth and.
- The dental bleach system defined in claim 4 wherein said second compartment comprises a container for said fumed silica, said container holding a body of said fumed silica sufficient for a single patient application.
- The dental bleach system defined in claim 4 wherein said mixing means comprises a spatula means for blending said hydrogen peroxide with said fumed silica.
- obtaining a body of fumed silica;.
- releasably sealing said tray with a cover, said cover being selectively removable to expose said hydrogen peroxide prior to exposing said fumed silica;.
- forming a bleaching paste by mixing said solution of hydrogen peroxide with said fumed silica in said mixing chamber; and.
- The method defined in claim 9 wherein said obtaining step includes providing said body of fumed silica as a single patient quantity of fumed silica and sealingly enclosing said body of fumed silica in said mixing chamber.
