Innovation of Production Line for Producing of Nanofibers Using TRIZ

Original language description

An increase in the production of production lines for inorganic nanofibres is a very complicated and complex problem that depends on the intensity of the electrostatic field. This complex system may show, under given input and output conditions, variable and nearly chaotic behaviour that may consequently cause fluctuations in the electric field intensity manifested by reduced efficiency of the process. An increase in the intensity of the electrostatic field may be carried out by known methods, for example by increasing the electric potential, changing of the environmental conductivity between the electrodes through changing the relative humidity or by replacing the air with an inert gas. However, the higher total intensity of the electrostatic field may not lead to an increase in process efficiency or productivity. This is due to the fact that the main parameter is involved especially in the spatial intensity distribution of the electrostatic field. Other important parameters having an impact on the optimum process are the distance and the type of electrodes, the chemical structure and properties of the polymer solution, ambient temperature, intensity of vapour removal and others. Through TRIZ tools the influence of the polymer reservoir geometry on the electrostatic field distribution were studied. The structural geometry of the polymer reservoir carries a rotating electrode. It was found that the geometric design and the relative permittivity of the used construction materials have a significant effect on the final distribution and the maximum electric field intensity at a given electric potential. The resulting intensity of the electric field can be understood as a system that is described by a complexity. This system includes subsystems in the form of input parameters such as electrical potential, the polymer type, humidity and temperature of the environment, duration of spinning, as well as the structural design of the polymer reservoir geometry.
