Web24 Jan 2024 · Silica greases have excellent heat resistance. The upper operating temperature of silica grease is determined by the base oil with which it is combined. Silica inherently has poor water resistance, but when treated its water-resistant can be increased. Silica is also a very efficient thickener as it has a small particle size (micron level). 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
Web23 Mar 2024 · To determine the hydrodynamic and contact force contributions to the shear thickening process, Lin et al. investigated the shear thickening behavior in the interaction of micron-sized silica and latex particles. They found that as the suspension gets thickened, increasing the shear rate causes the contact contribution to growing while the … The effect of multiple shear rate scans on the shear-thickening behaviors of the silica fluids is shown in Fig. 4 with the viscosity as a function of shear rate for the 15% fluid with 15-nm particles. It can be noted from Fig. 4that the 15 nm silica fluid can still exhibit remarkable shear thickening behavior even after five … See more In this paper, we systematically studied the effects of particle size, including both the nanoparticles and microparticles, on the shear thickening behaviors of … See more The effect of temperature on the viscoelasticity of the silica fluids is given in Fig. 2.

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 … front range alf in fairfield mtWebA 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.
