What is the mechanical strength of electrode paste
The mechanical strength of electrode paste includes compressive strength, flexural strength and tensile strength
The height of the electrode paste refers to the height from the upper end of the electrode clamp to the top end of the electrode paste. If the electrode paste is too high, the coarse and fine particles in the electrode paste are prone to delamination, or the electrode cylinder is expanded due to too high paste column pressure. If the electrode paste column is too low, it is difficult to obtain a dense electrode due to too low paste column pressure and poor filling. The electrode paste is consumed too fast. Proper height of electrode paste column is beneficial to improve the quality of electrode baking and reduce consumption.
The mechanical strength of the electrode paste includes compressive strength, flexural strength and tensile strength. The mechanical strength of carbon products is anisotropic, that is, the composition of raw material particles of carbon products is different in the horizontal and vertical directions. Due to the production method of the electrode paste, we will not discuss the anisotropy of the mechanical strength of the electrode paste here. The raw material composition of the electrode paste, that is, different raw materials, the particle size and proportion of raw materials, the thickness and proportion of powder, and the content of coal tar pitch have an impact on the mechanical strength of the electrode paste. We will discuss it separately.
