Whether the electrode paste is toxic or not, we should start with the composition of the electrode paste.
The main cost of electrode paste is electric forged anthracite, followed by residual poles. Pitch and coal tar account for a small proportion, and coke powder and graphite powder are present in a small amount.
In such a ratio, the electric forging coal residue is non-toxic and harmless. Pitch and coal tar have a certain irritation and should be protected during operation.
