Graphite electrode rod before adding aluminum dihydrogen phosphate.
Graphite electrode rod after adding aluminum dihydrogen phosphate
It can be clearly seen from the figure that the difference between the two graphite electrode rods is that the density of the graphite electrode rods to which aluminum dihydrogen phosphate is not added is very low, because the raw materials cannot be tightly bonded together, and such graphite electrode rods have not only a short service life. And still can’t play a good role in the product.
After adding aluminum dihydrogen phosphate, the product has obvious quality improvement, not only can the raw materials be closely combined, but also can play the role of anti-oxidation, anti-corrosion, wear resistance and high temperature resistance.
