Inorganic Fillers

At the end of 19th century, the modification of silica has brought revolution in the field of nanocomposites and gained the attention of researchers again by the development of the mesoporous silica class. Silica when used with elastomers provides distinctive characteristics merging the superior properties of inorganic fillers, such as hardness, increased thermal strength, and mechanical stability along with the processability, elasticity, and plasticity of the organic polymers. When carbon black is treated with elastomers instead of silica, it provides greater level of reinforcement because the surface of silica is polar and hydrophilic, but it has greater tendency to adsorb moisture, which affects the ionization of silanol groups. The reason behind switching to silica is adverse effects of carbon black on environment. When silica is added in greater amount, it increases the viscosity of rubbers significantly. The high viscosity causes the processing extra difficult by generating excessive wear and tear over the processing equipment. The increase in viscosity is associated with the strong interaction among the silica particles. It has also been reviewed that the use of silica as filler in elastomers was hindered as far as bifunctional organosilanes were discovered. These are referred to as surface-modifying materials and are initiators for treating silica surfaces to make the filler compatible and friendly to elastomers.

The Cost

The mechanical properties of porcelain are strongly influenced by the generated thermal stress during processing. When quartz particle size is reduced its influence on the technical properties of ceramic products such as tiles and porcelains are changed. In this work, the properties of triaxial ceramics materials were evaluated using quartz of different particle size distribution. It was reported strong variations in mechanical strength and thermal shock strength. Although the cost of milling is increased to reduce quartz particle size, it can be compensated by its implicit advantages. The experimental results were very interesting showing the way that quartz particle size influences the analyzed properties. A significant improving in porcelain strength and thermal strength was obtained.

Set Up

As a kind of new renewable energy, biogas is receiving more and more attentions. However, its combustion duration is longer than diesel, which causes the bigger thermal load of engine. A geometry model of a biogas engine’s piston is set up in Proe 4.0. The temperature fields, thermal stress and thermal deformation of the piston are calculated using ANSYS 10.0. The result shows that the thermal load of biogas engine is still within the thermal strength of the material, thus provides supporting evidence for the popularity of biogas.
