1. Increasing Volume Contraction to Enhance Bulk Density
The weight loss of calcined products during graphitization is about 2.6%. To increase the bulk density of bio-products in the graphitization process, it is essential to enhance volume contraction.
2. Bulk Density of Calcined and Calcined Products
Impregnation degree is a standard measure of the level of impregnation, primarily determined by the degree of impregnation displayed. The coking value from calcination is related to the adsorbent filler. If the permeability is not changed, improving the permeability and area of the filler can effectively reduce the coking value.
3. Method of the First Calcination Process
To control the final bulk density of the product, it is necessary to measure and control the bulk density of the green product. It can be seen that a high binder content is detrimental to the bulk density of the product since 40% (by weight) of the binder will exude during the calcination process. Practical experience has also shown that too little binder results in many different pores in the green product, reducing bulk density and affecting other system performance analysis indicators.
To achieve a suitable paste for pressed plates with the minimum amount of binder, some high-purity graphite can be added to the mix to reduce the extrusion resistance. The shrinkage of the green product during calcination is related to many factors, and these factors often interact with each other.
