The viscosity change of coal pitch in the anode has an important influence on its action. Viscosity is a physical property of coal pitch that reflects the degree of fluidity and adhesion to it. In anode production and use, viscosity has a positive impact on:
Bonding effect: The viscosity of coal pitch determines its bonding performance. If the viscosity is too high, the bitumen may become too dense to flow easily, resulting in insufficient penetration and bonding to the aggregate. Too low can lead to uneven distribution or premature loss of asphalt, which also affects the bonding effect. The right viscosity ensures an effective combination of bitumen and aggregate and improves the overall performance of the anode.
Pouring and processability:
During the production process, the viscosity of coal pitch has a significant impact on the pouring and processing properties. High-viscosity bitumen can better maintain the stability of the paste, making it less likely to separate or settle. At the same time, the high viscosity also helps to maintain the fluidity of the asphalt during pouring, so that it can smoothly fill the mold and wear a uniform structure.
Anti-corrosion structure: The viscosity of coal pitch also affects the use effect as an anti-corrosion coating. The coating should have good adhesion and sealing properties to effectively isolate the metal surface from contact with external corrosive media. Higher viscosity bitumen results in denser coatings, reducing porosity and cracks, and improving corrosion protection.
Electrical conductivity: The viscosity of coal pitch also affects its conductivity to a certain extent. High viscosity bitumen may lead to reduced electrical conductivity because high viscosity may hinder the transfer of electrons. Low-viscosity bitumen may improve electrical conductivity and facilitate the conduction of electric current.
Summary. Changes in the viscosity of coal pitch in the anode can affect its performance as a binder, anticorrosive material, pouring material, and conductive medium. Therefore, for the use of coal pitch in the anode manufacturing process, the appropriate viscosity should be maintained to obtain the best performance and effect.
