1.Increasing the volume shrinkage to increase the bulk density of the deposit.
After graphitization, the weight loss of the calcined product is about 2.6%. If you want to increase the bulk density of the microbial product during the graphitization process, the fundamental way is to expand the volume shrinkage.
2.The bulk density of calcined and calcined products
The degree of impregnation is a standard amount that first determines the level of impregnation. The calcination value of the carbonized value is related to the adsorption filler. For example, if the porosity is not changed, the carbonization value can be effectively reduced by improving the permeability and surface area of the filler.
3.Method of primary calcination process
To control the final product’s bulk density, it must be measured and controlled in the production of green products. It can be seen that the larger the binder, the worse it is for the bulk density of the product, because the binder will overflow during the calcination process. Practice has also proved that too little binder will result in many different porosities in the green products, which will also reduce the bulk density and have an impact on other system performance indicators.
In order to obtain a suitable paste for pressing with a minimum amount of binder, a portion of high-purity graphite can be added to the slurry to reduce the pressure resistance during extrusion. Many factors are related to the shrinkage of green products during the calcination process, and these factors often interact with each other.
