BATTERY PASTE MANUFACTURE

3.5% carbomer (Carbopol®)* powder dispersed into potassium hydroxide solution.

PROBLEM:

Carbomer mixture in water and potassium hydroxide becomes extremely viscous almost immediately since the KOH is basic and that activates the carbomer gel.  It is virtually impossible to avoid lumping.

RESULTS:

Carbomer powders are feed directly into the rotor/stator mixer from the bottom of the mixing vessel utilizing vacuum. Anchor/scraper mixer cleans off viscous material from side walls.  Auxiliary mixer provides blending of additional active ingredients prior to Deaeration step.

AB MIXER:

Model MXM-1000 ARDE MAXIMIXER system.

Air free gel prevents any voids in the battery for longer battery life and reduced rejects.
