Method For Increasing The Bulk Density Of Graphite Products

1. The raised volume is closed to increase the deposition density
After graphitization, the weight loss of roasted products is about 2.6%. If you want to increase the density of microbial products in the graphitization process, you must increase the shrinkage of the volume.
2. Bulk density of roasted and roasted goods
The degree of impregnation is a standard quantity to consider the degree of impregnation, and it is first determined by the degree of impregnation. The calcined coke value is related to the adsorption filler. If the air permeability is not changed, the coke value can be effectively reduced by improving the permeability and area of the filler.
3. The method of one-time roasting process
To automatically control the final product density, it is necessary to accurately measure and control the density of raw products. It can be seen that the binder is too large, which is not good for the deposit density of the product, because 40% (by weight) of the binder will overflow during the firing process. Practice has also proved that if there is too little adhesive, a large number of different porosity will appear in the raw product, which will also reduce the bulk density and affect other system property analysis indicators.
In order to obtain a paste suitable for the profiling plate with the least amount of adhesive, a part of high-purity graphite can be added to the seasoning to reduce the frictional resistance of pressing out. The shrinkage of the raw product blank during the roasting process is related to many factors, and these factors Usually also affect each other.
