Thickening silica
WebSurface modification of silica particles, synthesized using the Stöber method, was carried out using methyl trimethoxy silane (MTMS) and 3-aminopropyltriethoxy silane (APTES) to prepare silica particles with hydrophobic and hydrophilic surfaces, respectively. Shear thickening fluids (STFs) were prepared from unmodi WebHow to thicken an epoxy resin with fumed silica. It is interesting to note that the presence of a small concentration of polar molecules in a non-polar fluid can have a synergistic effect in the thickening behaviour; through a …

Cornstarch is a common thickening agent used in cooking. It is also a very good example of a shear-thickening system. When a force is applied to a 1:1.25 mixture of water and cornstarch, the mixture acts as a solid and resists the force. Silica nano-particles are dispersed in a solution of polyethylene glycol. The silica particles provide a high-strength material when flocculation occurs. This allows it to be used in applications such … WebA 57-year-old man with a history of exposure to silica for 32 years presented with pleural thickening of the lower lobe of the left lung and a chronic right-sided pleural effusion without any radiographic evidence of parenchymal nodules in either lung.

Websilica is subjected to flame hydrolysis together with a second volatile compound (of a metal). The thickening ability is a property of amorphous silicas which has important technical applications. The specific molecular structure of these substances makes them thixotropic, i.e. they have pseudoplastic and structurally viscous properties. 1.6 Uses
