Flexible Graphite Bulk Roll is made by high quality Graphite Powder. We use the well-advanced equipment, suppressing expansion the graphite powder in high temperature to get the low sulfur content Flexible Graphite Bulk Roll. Flexible Graphite Bulk Roll can be made to various types and sizes.
Main Specifications of Flexible Graphite Bulk Roll:
Thickness: 0.1mm --- 1.0mm length: 1m --- 500m
width :1000-1500mm Density :0.7 --- 1 .5g/cm3
The producing process of the flexible Graphite Sheet:
1. A brief introduction of the whole production line.
We use this production line(as the following photos present) to produce the flexible graphite sheet.This production line adopts international advanced technologies, making us produce high qualityflexible graphite sheet and having become a powerful tool for us to meet the different requirements of our customers.
2. The raw material-expandable graphite
The expandable graphite comes from good mine and mineral resources, making sure the superior quality of the expandable graphite and a good start of the production from the beginning.
3. The mixing process.
In this process, the expandable graphite is poured into the mixer to be well mixed. And after the mixing, they go into the hopper.
4. The expansion process.
After mixing, the expandable graphite goes into the expansion stove to be high temperature expanded. The S, chlorine and many other chemical elements are get rid of from the expandable graphite in the expansion stove.
5. The transportation of the having been Expanded Graphite.
In this process, the graphite is transported by the draught fan from the expansion stove to the material pool.
6. The preliminary roll-forming of the flexible graphite sheet.
After passing through the material pool, the flexible graphite sheet is preliminary formed.
7. The adjusting process of the density and thickness of the flexible graphite sheet.
There are many groups of rolls in the production line. Through these rolls, the adjusting of the density and thickness is fulfilled.
Then the flexible graphite sheet is produced.
