I need to disperse silica aerosil in epoxy resin using a high shear mixer (Turrax T 25), but I dont have idea about the dipersion ideal conditions. Could someone give me some tips?
Depending on type of epoxy that you are using, and the silica aerosil ratio that you want to add in etc., you can choose the right parameter. T 25 ULTRA-TURRAX works with the volume 1 to 2000 ml (H2O) and maximum viscosity of the material is 5000 mPAS. Is it the one you are asking for? In some cases, temperature, solvent can aid to reduce the viscosity of the material. But keep in mind, the higher speed can generate the heat, the local heat sometime go high and can damage the plastic part of your ULTRA-TURRAX as well as your materials. You need to check the limit of your unit and your material. Also make sure there is no chemical reaction during mixing due to the heat. Attached is one research article using ULTRA-TURRAX for epoxy.
@TriDung(T.-D.) Ngo Thank you very much for your response and the attached material was very helpful!
