Dimethicone etc..
The agitator is polytetrafluoroethylmaterial material, and rotating speed can be up to 900r/min, and material is realized by this agitator
Uniform mixing.
The utility model connects each interface using stainless steel tubing, can prepare the titanium of the doping such as Nb, Zr, Ag, Y, La, V
Sour lithium, can also prepare that carbon, CNT, graphene be single or the lithium titanate of compound coating.
The utility model can effectively prevent the reunion precipitation in CNT fill process, so as to solve product cut size
The problem of larger and uneven, experimental repeatability is poor；Charging rate can be controlled, easy to operate, automaticity is high, is produced into
This is low, available for large-scale mass production CNT and oxide composite；Technique is simple, environment-friendly, safe,
Energy consumption is low, and experimental repeatability is poor.
