Electrostatic Properties Of Solid-liquid Mixing Process
Abstract: To resolve this issue in the process of solid-liquid mixing static problems, which is really good control static, static parameters including the potential need to master the electric field strength, the amount of charge, charge to mass ratio, current and electrostatic energy, etc.; simultaneously due to the presence of powder and liquid mixing the electrical parameters must be understood that the powder material and a liquid material include powder resistivity, resistivity, dielectric constant, capacitance, time constant and minimum ignition energy, etc., on the other hand, it needs to understand the electrostatic law, i.e. production ratio, the greater transmission speed mixing, the powder, the more intense mixing liquid surface friction, and therefore the greater the amount of static electricity generated, but also the greater static hazards. In this issue, the clever use of gravity to provide dynamic experiments, the use of battery ABCo provided strong powder filled in the laboratory to simulate the electrostatic properties of the solid-liquid mixture in the industry during transport. Meanwhile, the company's strong ABCo- powder chemical composition of confidentiality, but also to our research process has brought great difficulties.
