Effect of the ratio of graphene oxide(GO) and multi-walled carbon nanotubes(MWCNTs) on metal friction and wear during mixing

Internal mixer is an important mixing component in industrial applications. Studies show that when a mixer operates for a long time, wear may appear at the end face of the internal mixer. On the other hand, abrasion of the end face increases the gap between the mixing chamber and the end face. Then,...
