Rubber Dewatering & Devolatilization

Twin screw Extruder Rubber De-water & Evaporation Production Lines


It is one of the most important application in polymerization post-process that dewater the rubber of both natural and synthetic by co-rotating twin screw extruder.


According to the features of different kinds of rubber, it may need to remove of the water, residual solvent, envocating agent, catalytic agent etc.  from the protomere surface or from its inside. 

Continuous metering feedstock, multiple extrusion, interface update, evaporation, flashing, vacuum exhaust, granulation and other process engineering can be done at the same time by the extruder. The content of the volatile component of the finished rubber can reach high technic index.

This extuder makes the conventional intermittent operation become continuous so that can save engery, space, manpower, improve operational environment and enhance products stability.


Advantages

• Continuous

• Efficient

• Energy-saving

• Environment-friendly


Typical Application

The twin screw extruder for rubber deep dewatering that Chuangbo produced can apply to lot's of rubbers: FPM (fluororubber),  IIR (buryl rubber),  CIIR (chlorinated buryl rubber),  BIIR (brominated buryl rubber),  SBR (styrene-butadiene rubber), IR (isoprene), CSM (chlorosulfonated polyethylene), AC M(acrylic), ECO (epichlorohydrin), etc.
