China Silicon Nanopowder Manufacturers, Suppliers, Factory

The 17th International Surface Treatment, Electroplating and Coating Exhibition will be held from May 15th to 17th at the Poly World Trade Center Expo in Guangzhou in 2024. The exhibition has always been in line with the development needs of the industry, leading the innovation of surface treatment technology and industrial upgrades.

The integration of science and technology has brought mankind a stunning innovation, Precious Metal Nanoparticle Iridium Powder, which is one of the most used valuable elements in industrial and non-industrial sectors. This stunning product is not only precious, but it can also provide outstanding applications in different technology-related fields.

​The difference in cohesive force between different powders is due to the type and strength of interparticle forces (van der Waals forces, capillary forces, electrostatic forces, etc.), and its core influencing factors include particle size, surface roughness, moisture content, and material properties, resulting in cohesive force that can span multiple orders of magnitude (from 10 ⁻⁶ N to 10 ⁻¹ N). This difference can be quantitatively described through the aggregation feature index, surface tension, and roughness correction model.

Silicon dioxide SiO2 often has a decisive impact on the performance of systems, whether it is silicone rubber, thin films, or electronic packaging materials.

Copper is different from metals such as aluminum and nickel in that it is difficult to form a dense and stable intrinsic passivation layer on its surface. Therefore, the exposed copper surface will be continuously oxidized and corroded by oxygen and water vapor in the air. The smaller the particle size and larger the specific surface area of copper powder, the easier it is to rapidly oxidize to produce products such as cuprous oxide (Cu2O) and copper oxide (CuO). This oxide insulation layer significantly reduces the conductivity of copper powder and hinders particle sintering connection, resulting in degradation of the performance of the conductive paste.

When making certain products, such as paints, coatings and electronics, it is necessary to use nanopowders. However, these powders can be difficult to disperse and can clump together, causing issues with product quality. To combat this problem, dispersants are used to effectively separate and disperse these powders. In this article, we will discuss the use and benefits of dispersants for the dispersion of nanopowders.
