Influence of formula design on molding process and final product performance index

It is generally believed that the design of process technology formula will directly affect the shaping effect and structure of carbon and graphite raw products, which is a mistake in practice; the design of process technology formula has fully considered the performance of raw materials, particle size composition, paste plasticity, and has no significant impact on the structure of raw products without violating the major principles. But the advantages and disadvantages of the formula design, the bulk density of the raw products and the after effect of extrusion elasticity will have a certain reflection.

 

Whether the technological formula is reasonable or not is mainly reflected in the thermal stability, strength and bulk density of roasting and graphitization, whether there is shrinkage crack or crack expansion; at the same time, the volume density, compressive bending resistance, modulus of elasticity and other indicators of the final product will have obvious changes, which are mainly manifested in poor thermal shock resistance and oxidation resistance, low mechanical strength and low mechanical strength.

 

For different manufacturers, their technological formulas are different.
